The results of the crossing of the Kalmyk cows with the Galloway bulls are presented. The indicators of growth and development in crossbred bulls in comparison with purebred from birth to 8 months of age were studied. It has been proven that the crossing of Kalmyk cows with Galloway bulls in the conditions of the Saratov Trans-Volga region is an effective breeding method for increasing the efficiency of the beef cattle industry. Half-blooded bulls of Galloway breed compared to the pure-bred Kalmyk at 8 months of age had a large live weight of 36.9 kg or 17.4%. And also characterized by the best development of articles physique. In terms of the depth of the chest, the excess was 5.95 cm or 12%, the width of the chest behind the shoulder blades was 6.03 cm or 20%, and the oblique length of the body was 5.9 cm or 5%. In general, the crossbred animals possessed the best meat forms and ratios of physique articles.

Full textAbstract:
Our study was conducted to determine the effect of production factors (breed, sex) and aging time on the textural properties of beef using instrumental measurement of tenderness. Meat was obtained from Galloway, Simmental, Charolais, Czech Fleckvieh breeds and their crossbreeds. Meat was either unaged or aged for 14, 28 or 42 days. The tenderness was characterized by Warner-Bratzler test and compression test using Tira-test device. The cooking loss of meat juice was also evaluated. Analysis of variance at 5% significance level showed that tenderness was influenced by all tested factors (breed, sex, aging time). The shear force decreased with aging of meat. The correlation between shear force and compression test was 0.257 (p ≤ 0.001). The differences in tenderness were found among breeds. The highest initial shear force was measured in Simmental (151.98 N). Compression test showed better tenderness in Czech Fleckvieh and Galloway than in Simmental, Charolais and crossbreeds. Meat from bulls was significantly (p ≤ 0.001) less tender than from heifers. There was a significant (p ≤ 0.001) increase of cooking loss of meat juice during aging from 25.3% after slaughter to 34.0% after aging period. The research results could be useful for determination whether specific cattle breeds can produce tender meat with good aging patterns. According to findings of the current study it is especially necessary to emphasize that factor of aging time exceeded the influence of breed and sex on tenderness. The study also suggests extending of aging period to 6 week to assure tenderness of beef.

The objective of the present study was to compare the quality of the carcass and beef of bulls genotyped for leptin (TT and CT) of the Czech Fleckvieh cattle with Galloway and Charolais bulls. Analysed were 232 bulls. The quality of the carcass body was significantly (p < 0.05) the highest in Charolais bulls (78.1% beef, 1.66% fat) as compared with bulls of the Czech Fleckvieh cattle (77.06% beef, 2.52% fat). The percentage of bones in the weight of the carcass body was the same in all breeds (20.49%; 20.28%; 20.24%, respectively). Indicators of the nutritional quality apart from the energetic value of meat of the Galloway and Charolais breeds were not significantly (p > 0.05) affected by the breed. In terms of fatty acids significant (p < 0.01) differences were discovered in the intramuscular fat of the MLT between the Czech Fleckvieh cattle and both beef breeds in the levels of C16:0; C20:0; C14:1; C16:1; C20:1; C20:2 and rate of the C14index. A significant (p < 0.05) difference in the level of oleic acid was detected between the meat of the Czech Fleckvieh cattle (37.77 g.100g −1) and Charolais (41.23 g.100g−1). From the viewpoint of human health the most favourable rates of fatty acids (C14index = 22.07; C16index = 13.63; C18index = 64.19; AI = 0.67) were seen in the meat of the Czech Fleckvieh cattle. The smallest diameter of muscle fibres (35.61 µm) was detected in the Czech Fleckvieh cattle as compared to the Galloway (37.60 µm) and Charolais (38.01 µm) breeds.

Представлена система содержания, кормления, производственного использования и селекционная работа с мясным скотом галловейской породы в стаде племрепродуктора, в климатических и кормовых условиях Костромской области. Исследовано влияние паратипических и генетических факторов на эффективность разведения мясного скота в Нечернозёмной зоне Российской Федерации. Ресурсосберегающая технология производства мяса при чистопородном разведении галловейского скота, применяемая на предприятии, позволяет получать высокие показатели воспроизводительной способности животных и интенсивности роста молодняка: выход телят на 100 коров – 85–88%, среднесуточные приросты живой массы молодняка в период выращивания – 852 г. Это свидетельствует о хорошей реализации генетического потенциала животных галловейской породы, при одновременном соответствующем научном обеспечении селекционной работы с племядром стада. Успешная адаптация мясного скота галловейской породы является предпосылкой для перспективного его разведения и повышения эффективности отрасли мясного скотоводства. The system of management, feeding, industrial use and breeding with beef cattle of the Galloway breed in herd of pedigree breeding unit, in climatic and fodder conditions of the Kostroma region is presented. The influence of paratypic and genetic factors on the efficiency of breeding beef cattle in the non-black-earth zone of the Russian Federation was investigated. The resource-saving technology of meat production in purebred breeding of the Galloway cattle used at the enterprise allows to obtain high indicators of animal reproductive ability and growth intensity of young animals: calf yield per 100 cows – 85–88%, daily live weight gain of young animals during the rearing period – 852 g. This indicates a good realization of the genetic potential of the Galloway animals breed, while ensuring appropriate scientific support for breeding work with the herd nuclear stock. Successful adaptation of the Galloway beef cattle is a prerequisite for its promising breeding and improving the efficiency of the beef cattle breeding industry.

Full textAbstract:
Genodermatosis such as hair disorders mostly follow a monogenic mode of inheritance. Congenital hypotrichosis (HY) belong to this group of disorders and is characterized by abnormally reduced hair since birth. The purpose of this study was to characterize the clinical phenotype of a breed-specific non-syndromic form of HY in Belted Galloway cattle and to identify the causative genetic variant for this recessive disorder. An affected calf born in Switzerland presented with multiple small to large areas of alopecia on the limbs and on the dorsal part of the head, neck, and back. A genome-wide association study using Swiss and US Belted Galloway cattle encompassing 12 cases and 61 controls revealed an association signal on chromosome 29. Homozygosity mapping in a subset of cases refined the HY locus to a 1.5 Mb critical interval and subsequent Sanger sequencing of protein-coding exons of positional candidate genes revealed a stop gain variant in the HEPHL1 gene that encodes a multi-copper ferroxidase protein so-called hephaestin like 1 (c.1684A>T; p.Lys562*). A perfect concordance between the homozygous presence of this most likely pathogenic loss-of-function variant and the HY phenotype was found. Genotyping of more than 700 purebred Swiss and US Belted Galloway cattle showed the global spread of the mutation. This study provides a molecular test that will permit the avoidance of risk matings by systematic genotyping of relevant breeding animals. This rare recessive HEPHL1-related form of hypotrichosis provides a novel large animal model for similar human conditions. The results have been incorporated in the Online Mendelian Inheritance in Animals (OMIA) database (OMIA 002230-9913).

Изучен породный состав и численность племенного скота мясного направления продуктивности в Российской Федерации. На долю мясных пород в мире приходится 40% от всего поголовья крупного рогатого скота. В России специализированное мясное скотоводство как самостоятельную отрасль животноводства начали создавать в начале 30-х годов прошлого века. На современном этапе в нашей стране разводят 12 пород крупного рогатого скота мясного направления продуктивности. К наиболее многочисленным относят абердин ангусскую, калмыцкую, герефордскую и казахскую белоголовую. Относительная численность животных этих пород составляет около 97% от всего поголовья скота мясного направления продуктивности. Лимузинская, галловейская, обрак, шаролезская, салерс имеют небольшой удельный вес, и совсем незначительный — у таких пород, как симментальская мясная, русская комолая и бланк-блю бельж. Территориальные и климатические особенности России позволяют в настоящее время заниматься мясным скотоводством в 59 регионах во всех федеральных округах. В 2000 году разводили 9 пород в 7 округах с численностью племенных животных около 82 тыс. голов. В 2019 году поголовье племенного мясного скота составило более 359 тыс., принадлежащих 12 породам, что в 4,4 раза больше по сравнению с 2000 годом. The article discusses the breed composition and number of breeding cattle for meat production in the Russian Federation. There are thousands of different breeds in the world, but only a few dozen are classified as meat. The share of beef cattle in the world accounts for 40% of the livestock, respectively 60% are dairy cattle. In Russia, specialized beef cattle breeding as an independent branch of animal husbandry began to be created in the early 30s of the last century. At the present stage, 12 breeds are bred in the beef cattle breeding of our country. Numerous breeds include Aberdeen Angus, Kalmyk, Hereford and Kazakh white-headed. The relative number of these breeds is about 97% of animals in the meat production direction. The rest of the breeds (Limousine, Galloway, Obrak, Charolais and Salers) have a lower specific weight. It is necessary to distinguish breeds with an insignificant specific gravity - these are Simmental meat, Russian hornless and blank-blue belge. The territorial and climatic features of Russia currently allow for beef cattle breeding in 59 regions in all federal districts. In 2000, 9 breeds were bred in 7 districts with about 82 thousand breeding animals. In 2019, the number of pedigree beef cattle amounted to more than 359 thousand heads belonging to 12 breeds, which is 4.4 times more than in 2000.

Full textAbstract:
Ten clinically healthy bulls equal in weight were chosen from eight meat cattle breeds maintained in the same geographical conditions using the extensive grazing method. After slaughtering, muscle tissue samples were taken from the musculus longissimus and pars thoracis, and dry matter, nitrogenous substances, fat, and the levels of essential (EAAs) and non-essential (NEAAs) amino acids were determined. Significant differences were found between the monitored genotypes in the contents of dry matter, nitrogenous substances, fat, EAAs, and NEAAs (P ≤ 0.05). The highest concentrations of nitrogenous substances in muscle tissue were detected in the Limousine breed and the lowest in the Aberdeen Angus breed; the highest fat content was found in Aberdeen Angus and the lowest in Galloway. Out of the total sum of EAAs, the highest percentage in the dry matter of muscle tissue in all genotypes was found for Lys (8.8–10.4%), the lowest percentage was found for Met (2.4–2.9%). The value of Thr was approximately 4.6, Val 5.1, Ile 4.8, Leu 8.2, Phe 4.1, His 4.2, and Arg 8.0%. Significant differences (P ≤ 0.05) between the monitored breeds were found in all EAAs, except for Val and Leu. Regarding NEAAs, out of the total protein, the highest percentage was found for Glu (13.9–15.1%). Conversely, the lowest values were detected for Ser (3.8–4.1%) and Tyr (3.8–4.4%). The values of other NEAAs were approximately 9.3 for Asp, 4.0 for Ser, 5.3 for Pro, 5.5 for Gly, and 6.1% for Ala. Significant differences (P ≤ 0.05) were found between the monitored genotypes in all NEAAs except for Pro and Ala. In the dry matter of muscle tissue, out of the total protein, the sum of EAAs ranged from 50.6 (Meat Simmental) to 52.0% (Limousine), and NEAAs ranged from 48.0 (Limousine) to 49.4% (Meat Simmental). Apart from its effect on the biological value of meat, representation of individual amino acids is important to enhance its taste or smell.

Full textAbstract:
The objective of this study was to estimate genetic parameters for the results of classifying of carcass traits by the SEUROP method in beef cattle in the Czech Republic using linear and linear-threshold models. Genetic parameters were calculated and evaluated in a set of 4276 animals of eleven beef breeds and crosses with dairy and dual-purpose breeds (Aberdeen Angus – 1376, Hereford – 994, Simmental – 651, Charolais – 524, Piemontese – 185, Galloway – 162, Blonde d’Aquitaine – 147, Limousine – 106, Highland – 53, Gasconne – 44, Belgian Blue – 34) in 2005–2008. Aberdeen Angus, Hereford, Charolais and beef Simmental were the most numerous breeds. Fixed effect of a classifier, fixed regression on age at slaughter by means of Legendre polynomial of the second degree separately for the each breed and sex and fixed regression on heterosis coefficient were included in a model equation. Genetic parameters were estimated by a multi-trait animal model using a linear model and a linear-threshold model in which carcass weight (CW) was considered as the linear trait and carcass conformation (CC) and carcass fatness (CF) grading as threshold traits. The heritability coefficient for CW differed only moderately according to the method of the genetic parameter estimation (0.295 in linear model and 0.306 in linear-threshold model). The heritability coefficient for CC was 0.187 in linear model and 0.237 in linear-threshold model. The heritability coefficient for CF grading was 0.089 in linear model and 0.146 in linear-threshold model. Genetic correlation between CW and CC was high (0.823 in linear model and 0.959 in linear-threshold model), the correlation between CW and CF was intermediate (0.332 and 0.328, respectively) and it was low between CF and CC (0.071 and 0.053). If CW was included in the model equation as fixed regression using Legendre polynomial, lower heritability coefficients for CC (0.077 and 0.078) and CF (0.086 and 0.123) were calculated and the correlation between CC and CF was negative (–0.430 and –0.429).

Abstract. Title of the paper: Milk ingestion and growth performance of suckler calves (cross breeds Galloway x F1 Galloway x Holstein Friesian) from a cow-calf operation. Effects of sex and of life age of calf and of the age of dam On cross breeds (Galloway x F1 Galloway x Holstein Friesian; 12 calves from first pregnancy, 13 calves from second pregnancy; 10 male and 15 female) in a cow-calf operation measurements of body weight were done repeatedly during growth after separating the calves from the dams for 150 min and than again after the calves had contacted the dams for 60 min. Measurements took place always at the same daytime. Milk ingestion of calves was assessed by way of body weight difference method. Acute body weight difference varied markedly between calves and increased with age. The fraction of positive weight difference of all measurements was between 57,1 % and 91,8 % in calves from first pregnancy and between 54,8 % and 90,5 % in calves from second pregnancy the means of which were not significantly different. Mean acute positive body weight changes developed with life age and body growth with different degree in male and female calves. Greatest acute positive body weight changes of calves could be measured at 40 to 70 days of age (70 kg to 100 kg body weight). Growth rate of calves showed greater inter- and intraindividual variation within the first 10 days of life age. Differences in growth rate between male and female calves were more profound in calves from first then in those from second pregnancy.

Full textAbstract:
Mannosidosis was diagnosed in four stillborn Galloway calves and an autolyzed full-term fetus from experimental matings of carrier animals. Gross lesions were moderate internal hydrocephalus, and pallor and enlargement of the liver and kidneys and arthrogryposis. Histologic changes in the central nervous system of each calf were marked foamy vacuolation of the cytoplasm of neurones in the cerebral cortex, thalamus and brainstem, and vacuolation of the Purkinje cells of the cerebellum. Spheroids were common throughout the brain and there was also consistent severe foamy cytoplasmic vacuolation of renal tubular epithelial cells and hepatocytes. The activities of α-mannosidase, the lysosomal enzyme whose activity is deficient in mannosidosis, and activities of five other lysosomal enzymes were compared in brain, liver, and kidney tissues of three mannosidosis-affected calves and normal calf tissues. Tissues from the affected calves had a marked deficiency of α-mannosidase activity compared with the normal tissues; the greatest deficiency was in the liver (99%) and brain (98%). Activities of the other lysosomal enzymes were elevated in the affected tissues compared with normal. Mannosidosis is a lysosomal storage disease that results from a defect in glycoprotein metabolism and affects man,18 Angus and Angus-related breeds of cattle, such as Murray greys,12,21 and the cat.4 The congenital disease is caused by an inherited deficiency of the lysosomal enzyme α-mannosidase,14 and is inherited in an autosomal recessive manner. Mannosidosis was recently reported in a number of aborted and stillborn Australian Galloway calves3 from an experimental breeding trial. This is more detailed account of the histological and biochemical results obtained during the trial.

The aim of this work was to evaluate growth potential of Blue‑Grey cattle in Czech conditions as the compare its growth traits to initial population. Suitability of specific conditions was evaluated based on growth ability and daily weight gains (DWG). Tested breeds included Shorthorn, Galloway and their crossbred variation called Blue‑Grey cattle. A total of 428 animals were evaluated over a period from 2010 until 2016. Birth weight, live weight at 120, 210 and 365 days of age was monitored for each animal. Also, DWG at 120, 210 and 365 days of age was part of the evaluation. Mixed model (SAS 9.3) was used for statistical evaluation. The influence of sex on growth ability was significantly (P < 0.05) in favour of bulls throughout the evaluated period. Purebred Shorthorns achieved highest weights (from + 2.5 for birth weight to +82.65 kg in weight at 365 days of age) (P < 0.05) and DWG (from + 147.26 g to + 300.37 g (P < 0.05) compare to purebred Galloway throughout the evaluated period. Weight and DWG of Blue‑Greys were significantly better in comparison with Galloway and were more comparable with Shorthorns. Therefore, growth ability was improved mainly by addition of Shorthorn blood. Good growth ability of Blue‑Greys combined with better environmental endurance from Galloway blood makes them well suited for use in organic farming conditions of Czechia.

Full textAbstract:
The Moghani is the main fat-tailed type of sheep in north-west of Iran and north-east of Turkey, where it is raised for meat, milk and carpet wool. In sheep, a wide range in litter size has been observed among different breeds and within breeds. Several genes have been recently identified that affect female fecundity in domesticated sheep such as BMP15 gene which encodes bone morphogenic protein 15 (Davis 2005 and Hanrahan et al,. 2004) and is a member of the transforming growth factor b (TGFb) super family (Galloway et al, 2000). The identification of the BMP15 mutation is important for the sheep industry and those involved in the study of mammalian fertility. In this study we investigated mutation of BMP15 gene in Moghani sheep in Iran.

The objective of the study was to compare the chemical composition and fatty acid profile in ten clinically healthy bulls of similar weight from eight meat cattle breeds. The animals were raised by extensive grazing under the same geographical conditions. Significant differences were observed between the monitored genotypes in terms of the dry matter content, nitrogenous matter and fats (P ≤ 0.05) in the musculus longissimus thoracis. The concentration of fats ranged from 68.5 ± 18.81 g (Galloway cattle) to 171.6 ± 43.3 g (Aberdeen Angus) per kg of dry matter. The total content of unsaturated fatty acids ranged from 20.0 ± 2.25 g (Aberdeen Angus) to 42.4 ± 7.87 g (Gascon); the total sum of monounsaurated fatty acids ranged from 17.0 ± 2.26 g (Aberdeen Angus) to 33.8 ± 3.61 g (Gascon); and the total sum of polyunsaturated fatty acids ranged from 3.0 ± 1.42 g (Aberdeen Angus) to 5.1 ± 3.99 g (Limousin) per 100 g of fat. The total content of n-6 fatty acids ranged from 2.4 ± 1.28 g (Aberdeen Angus) to 4.2 ± 3.59 g (Limousin) and the total content of n-3 fatty acids from 0.5 ± 0.16 g (Salers) to 1.1 ± 0.04 g (Gascon) per 100 g of fat. The properties we studied may predict the biological, dietetic, and culinary value of the meat.

Abstract. The objectives of this study were to describe ruminal fermentation, mean retention time (MRT) ofthe particulate digesta in the whole gastrointestinal tract and the apparent digestibility of nutrients in growing cattle of the genotypes Black-White Dairy Cattle (B), Galloway (G), and Highland (H). Two experiments were carried out in bulls aged 11–12 months (mean weight 260 kg) or 9–10 months (mean weight 210 kg) at the beginning and fed diets varying in the nutrient composition and nutrition level. B bulls had a higher rumenoreticular volume, a higher MRT when fed a low nutrition level, a higher ruminal pH and a lower acetate/propionate ratio in the rumen than G bulls (P<0.05). In comparison with H bulls, rumen pH and MRT were higher (P<0.05) and the acetate/propionate proportion, NH,sub>3 level, and the protozoa number in the rumen were smaller in B bulls. The differences between genotypes in apparent digestibility of organic matter (OM) and crude cellulose were small. In some cases digestibility was significantly (P<0.05) higher in B bulls as compared to G and H bulls. In B bulls, the digestibility of OM at 30 °C environmental temperature was 2 units lower than at 3 °C or 18 °C (P<0.05). The results show that B bulls implement a more efficient ruminal digestive process than do G or H bulls.

The aim of this study was to evaluate the muscle fibre diameter of bulls (n = 136), heifers (n = 38) and steers (n = 18). The influence of age at slaughter, weight at slaughter, net daily weight gain, SEUROP meatiness and SEUROP fatness on the muscle fibre diameter was observed. The group of animals included Czech Red Pied and its crossbreeds (F1) with the specialized meat breeds (Charolais and Galloway), further crossbreeds of hybrid bulls. Bulls were slaughtered at an average age of 587 days and average weight of 610 kg. The average age of heifers was 644 days and average weight at slaughter was 550 kg. The highest average age was that of steers (689 days) and they were fattened to the average weight of 610 kg. The sample of musculus longissimus lumborum et thoracis (m.l.th.) was used for the analyses. The results showed that the muscle fibres were stronger in diameter in the negatively selected (culled) heifers (p > 0.01) as compared to the category of bulls and steers. Apart from sex we also analysed the effect of age at slaughter of the individual animal categories on the fibre diameter. We discovered that the diameter of the fibre increased with age. The fibre diameter of bulls of up to 530 days of age was 37.86 µm and at the age of more than 601 days it was 39.81 µm. The diameter of the muscle fibres was also affected by the pre-slaughter weight. At lower weights the fibres of all categories of cattle were finer. Of growth factors affecting the fibre diameter we selected the net weight gain which is the general indicator of the life-long growth intensity and carcass yield. The fibre diameter in bulls and steers increased insignificantly (p > 0.05) with increasing net weight gains. We also analysed the effect of the SEUROP classification of cattle carcasses and discovered a stronger correlation between the diameter of muscle fibres and meatiness compared to the classification of fatness of the carcasses.

Представлен краткий анализ состояния племенных ресурсов мясного скотоводства России, проведена сравнительная оценка основных пород по комплексу признаков, характеризующих молочность коров, сохранность и интенсивность роста молодняка. Численность поголовья основных пород рассчитана на основе данных Ежегодников по племенной работе в мясном скотоводстве в хозяйствах Российской Федерации за 2015 и 2018 года по породной структуре и размещению пробонитированного скота по регионам. Племенной скот характеризуется более высоким продуктивным потенциалом по всему комплексу хозяйственно полезных признаков. Доля племенного скота в сельскохозяйственных организациях и К(Ф)Х сократилась с 18,9 до 17,4 %. Среди пород племенного поголовья скота высокой молочностью (220 кг и более) отличаются шаролезская, лимузинская, обрак и абердин-ангусская. Самым высоким выходом телят на 100 коров к отъему характеризуются калмыцкая (86 голов), казахская белоголовая (82 головы), галловейская (79 голов) и абердин-ангусская (71 голова) породы. По интенсивности роста молодняка лучшими показателями обладает скот пород обрак, симментальская мясная, лимузинская, шаролезкая и герефордская. Эти показатели пород имеют существенное различие по регионам, поэтому породное разнообразие является безусловным конкурентным преимуществом мясного скотоводства России. This article presents the analysis of breeding resources for Russian meat cattle industry and comparative assessment of main breeds by a set of characteristics that characterize the milk production of cows, the safety and growth rate of young animals. Based on data of breeds’ structure and breeding cattle’s placement by region, the number of main breeds’ livestock at the Russian Federation was calculated. To assess the number of main breeds’ livestock, we used the data from Yearbook of breeding work at dairy and meat cattle breeding in the Russian Federation for 2015 and 2018. Breeding livestock is characterized by higher productive potential for the entire range of economically useful features. The share of breeding livestock at agricultural organizations decreased from 18.9 % in 2015 to 17.4 % in 2018. The Charolaise breed, Limousine, Aubrac and Aberdeen Angus are characterized by high milk yield (220 kg or more). The highest yield of calves for weaning per 100 cows have Kalmyk breed (86 heads), Kazakh White-headed (82 heads), Galloway (79 heads) and Aberdeen Angus (71 heads). According to the intensity of young animals’ growth, the best indicators have Aubrac breed, Simmental meat, Charolaise, Limousine and Hereford. These indicators of breeds have a significant difference by region, so the breed diversity is the absolute competitive advantage of meat cattle breeding at Russian Federation.
