Abstract:
Factors which affect the carcass composition of beef cattle include breed type, plane of nutrition and slaughter weight. With increasing weight, the relative proportions of the carcass joints and tissues change and if these changes were known or could be predicted then cattle could be slaughtered at the desired carcass composition. Dairy bred calves for beef production can be classified into three breed categories -straightbred Friesians, early maturing beef breed x Friesians and late maturing beef breed x Friesians. The objectives of the present study were to compare the changes in carcass composition associated with changes in slaughter weight in Friesian (FF), Hereford x Friesian (HF) and Charolais x Friesian (CF) steers and to determine the effects of dietary metabolisable energy (ME) content.

Abstract:
Informativeness of eleven microsatellite markers suggested for parentage control in cattle by the International Society for Animal Genetics (ISAG) was studied in Finnish Ayrshire and Holstein-Friesian populations. Calculations were based on a sample of 100 non-sib artificial insemination bulls. Assuming one known parent the nine loci suggested for routine testing exhibited exclusion probabilities of 99.84% in the Ayrshires and 99.91% in the Holstein-Friesians. The addition of markers INRA23 and TGLA53, recommended for further investigations, increased the attained values to 99.94% in Ayrshires and to 99.98% in Holstein-Friesians. The recommended core set of six microsatellites provided a combined exclusion probability of 98.25% in Ayrshires and 99.32% in Holstein-Friesians. Although the combined values were high in general, a relatively low level of polymorphism was detected in some instances.;

Abstract:
ABSTRACTTwenty Friesian (group 1) and 20 buffalo (group 2) calves and 14 of each of lactating Friesians (group 3) and lactating buffaloes (group 4) were maintained in middle of winter conditions of Egypt for 2 months. The calves (groups 1 and 2) were of similar age (6 to 7 months) and average body weight (120 kg). The lactating animals were in the fifth season of lactation, non-pregnant, in mid lactation and yielded 12 to 14 kg milk on average daily. Similar groups of animals of the same types (groups 5, 6, 7 and 8, respectively), numbers, live body weights and physiological status were maintained under hot summer conditions for 2 months. The effect of hyperthermia during summer season on Friesians and buffaloes compared with winter was also studied.The results showed that buffaloes were more tolerant than Friesians to the environmental conditions of Egypt. In winter, buffalo calves had poorer (P < 0·05) food efficiencies (kg gain per MJ net energy), higher dry matter intakes (DMI, P < 0·05) and total lipids in the plasma (P < 0·01) than Friesians, while the contrary occurred in total proteins, albumin, phospholipids and cholesterol (P < 0·05). In summer, growth rate and the concentrations of total lipids, phospholipids and cholesterol in the plasma were higher (P < 0·01), and total proteins and albumin were lower (P< 0·01) in buffalo than in Friesian calves. In summer, in Friesians, both DMI and growth rate decreased (P < 0·05) and food efficiency as kg weight gain per MJ net energy was poorer (P < 0·05). In the plasma total proteins and albumin increased (P < 0·01) but haematocrit %, phospholipids and cholesterol decreased (P < 0·05). In buffalo calves, only total proteins and albumin increased (P < 0·01) due to heat stress.In lactating buffaloes, food efficiency was poorer (P < 0·01) and DMI and plasma haematocrit % were significantly higher, while the concentrations of total proteins, globulin, phospholipids and cholesterol in the plasma, and milk yield were significantly lower than in lactating Friesians in the winter season. Lactating buffaloes were poorer (P < 0·01) in food efficiency and had lower concentrations of total proteins, globulin and cholesterol than lactating Friesians in the summer (P < 0·01).

Abstract:
The objective was to measure teat canal length and diameter, teat diameter and teat wall thickness by ultrasonographic scanning in order to determine the differences in bovine breeds, and to study the influence of teat canal length and diameter on the occurrence of mastitis. A total of 269 lactating dairy cows of four different breeds (Brown Swiss, Simmental, Simmental crossbred with Red Pied, and Holstein-Friesians) from seven Upper Austrian dairy farms were examined. Average teat canal length of Brown Swiss animals was shortest (15·7 mm) followed by Holstein-Friesians (17·2 mm) and Simmental (18·3 mm). These differences in teat canal length were highly significant (P[les ]0·001). There was no significant difference in teat canal length between pure-bred and crossbred Simmentals. Differences of teat canal diameter between breeds were significant (P[les ]0·05). Brown Swiss animals had the largest diameters (2·0 mm) and Holstein-Friesians the smallest (1·7 mm). Differences in teat diameter between Brown Swiss, Holstein-Friesian and Simmental were also significant. No differences were found between the pure-bred and crossbred Simmental cows. The narrowest teats were in Holstein-Friesians and the widest in Simmental. Holstein-Friesians also exhibited the thinnest teat walls while the Simmental had the thickest ones. Teat canal length and diameter were correlated with udder health. Teat canals of healthy udders tended to be longer (17·4 mm) and narrower (1·8 mm) than teat canals of infected udders (15·8 mm, 2·1 mm; P[les ]0·001). A logistic regression model showed significant effects of teat canal length, teat canal diameter and lactation number on udder health.

Abstract:
Feed additives are widely used in beef production systems. Two trials were made to measure the effect of feed additives on the daily gain and feed efficiency of fattening beef cattle. In the first trial 48 Friesians and 48 weaned suckled calves weighing about 390 kg were fed individually on grass silage ad libitum together with 4 kg (Friesians) and 3 kg (weaned calves) bruised barley daily. The treatments were control (C), no additive; Avotan 150 mg/d (A); Flavomycin 45 mg/d (F) and Romensin 200 mg/d (R). Minerals and vitamins were given daily on the silage. In the second trial there were 240 Friesian and Exotic x Friesian bulls. They were housed on slats in groups of 15 and offered a mixture of bruised barley and soya bean meal ad libitum. The treatments were control, no additive; Flavomycin 50 mg/d, Romensin 210 mg/d and Salinomycin 150 mg/d. In trial 1 the steers were implanted with Ralgro and the heifers with Finaplix. No implants were used in the second trial. All the animals were weighed regularly and feed intake was recorded continuously. They were slaughtered when they achieved the required conformation and fat cover.

Dairy bulls have been genotyped for K-casein and P-lactoglobulin from semen samples by methodology based on a polymerase chain reaction (PCR), In this study, a previously described method for κ-casein A and B variants was extended to cover also the detection of the E variant. For β-lactoglobulin the variants A and B were genotyped by another PCR-based method. The frequencies of the κ-casein and β-lactoglobulin alleles were determined from 308 and 291 Finnish Ayrshire and 42 and 44 Finnish Friesian bulls, respectively. The bulls had been born between 1973 and 1988. There was no noticeable trend in the differences between allele frequencies over the years, the overall frequencies of κ-casein A, B and E being 0.62, 0.09 and 0.29 in the Finnish Ayrshires and 0.85, 0.14 and 0.01 in Finnish Friesians. The overall frequencies of β-lactoglobulin A and B alleles were 0.25 and 0.75 in Ayrshires and 0.56 and 0.44 in Friesians

Abstract:
ABSTRACTDutch Friesian purebred and Holstein Friesian-Dutch Friesian crossbred veal calves were used to study effects of genotype and feeding level on carcass composition. Carcass analyses were carried out on a total of 56 calves of two genotypes. Calves were reared for 22 weeks and given food dependent on age. From 1 to 16 weeks calves were given the same amount of milk replacer. At week 16, calves were assigned to either a high or low feeding level. Total energy intakes for the two groups were 5062 MJ metabolizable energy (ME) and 5408 MJ ME, respectively. Carcass weight and carcass composition traits showed no significant interaction between genotype and feeding level. Dutch Friesians had higher lean: bone ratios than Holstein Friesian crossbreds (3·85 v. 3·67). Differences between the two genotypes for fat and lean proportions in the carcass were not significant. Average proportions for lean and fat were 653 and 134 g/kg.Differences between the two feeding levels for carcass composition were significant. Calves on the low feeding level had 655 g lean and 131 g fat per kg, while calves on the high level had 645 g lean and 143 g fat per kg.The influence of the dissection technique on the differences in lean and muscle proportion between groups was studied on 18 carcasses using a standardized butcher's method (the Institute of Animal Husbandry (IVO) standard method) and the European Economic Community (EEC) reference method for beef. Average proportion of lean was 640 g/kg by the IVO method and of muscle was 557 g/kg by the EEC method. The difference between the two genotypes for lean proportion was smaller by the' EEC method due to the more complete separation between muscle and fatty tissue. Dutch Friesians had more intermuscular fat than Holstein Friesian crossbreds. Results of the EEC reference method indicate differences between the two feeding levels for fat as well as for protein deposition.

Abstract:
SummaryMilk samples from 250 Jersey and Friesian cows were collected and used to investigate the pattern of interrelationships between milk constituents and to test the effects of breed, sire, parity, stage of lactation, season of calving and milking time on them. Breed and sire effects were significant for all constituents. Overall Jersey cows produced significantly higher milk constituent concentrations except lactose, but the test-day yields in Friesians were significantly higher. Milk constituents had varying responses to parity, days in milk and season of calving. Correlation between different constituents and their regression on each other suggested antagonistic relationships. The pattern of association between constituent concentrations in Friesian cows was similar to that between test-day yields, indicating an equilibrium between volume and content of milk.

Memoria para optar al Título Profesional de Médico Veterinario
Esta memoria tuvo por objeto evaluar el resultado del cruzamiento bovinos de la raza Belga Azul, de gran conformación y rendimiento carnicero, con la raza lechera Holstein. En este manejo genético, muy común en la Unión Europea, se utilizan vacas adultas con menores índices productivos, de las cuales no es conveniente obtener reemplazos para el rebaño lechero. En lecherías cercanas a Los Ángeles, VIII Región, Chile, se inseminaron vacas Holstein con semen de toros Belga Azul, importado desde Bélgica. Los terneros machos fueron criados, castrados y engordados en las mismas lecherías hasta que se enviaron a una planta faenadora (Carnes Ñuble, Chillán, Chile), junto a los novillos Holstein controles. A un grupo de novillos Holstein puros (controles) se les aplicó un implante hormonal, normalmente utilizado en la engorda de novillos lecheros. Se evaluó el rendimiento a la vara, al desposte y las características de la canal de los novillos híbridos Belga Azul x Holstein y de los novillos Holstein Friesian puros, engordados en las mismas lecherías, con y sin implante hormonal. Se produjo un aumento estadísticamente significativo (p ≤ 0,05) para los híbridos Belga Azul x Holstein sobre ambos grupos de novillos Holstein con y sin implante hormonal, en las siguientes características: Peso de la canal (20 Kg. y 63 Kg. respectivamente), rendimiento en vara (casi 13% en ambos), rendimiento al desposte (7,55% y 6,59% respectivamente), siendo de mayor magnitud en los cortes mas valorados comercialmente, que a su vez son los de mayor demanda para exportación. En cuanto a las características cualitativas de la canal, se observó un aumento significativo (p ≤ 0,05) a favor del híbrido para el área del ojo del lomo de 38%, buen indicador de carnosidad de la canal

Abstract:
Azidotische Belastungen des Pansens gelten bei Milchkühen besonders in der Frühlaktation als weit verbreitet. Sie werden als subakute Pansenazidosen (SARA) für die häufigen Produktionskrankheiten verantwortlich gemacht. Ziele : dieser Untersuchungen waren a) die Kontrolle des Säure-Basen-Haushalt (SBH) bei HF- Hochleistungskühen im peripartalen Zeitraum zum Vorkommen von SARA, b) die Prüfung bewährter sowie neuer Methoden zur Pansensaftanalyse, c) die Analyse von SBH-Harnparametern sowie d) die Prüfung möglicher Beziehungen von Stoffwechselparametern im Blut zu SBH-Parametern im Pansensaft. Versuchsanordnung : In 10 Betrieben Niedersachsens wurden an je 10 Kühen Verlaufsuntersuchungen mit vier Proben/Tier durchgeführt: 1. Trockenstehperiode/Färsen -30 Tage ante partum (d a.p.) bis zur Kalbung; 2. 2 bis 7 Tage post partum (d p.p.); 3. in der Frühlaktation 8 bis 30 d p.p. und 4. in der Mittellaktation 80 bis 150 d p.p. Pansensaft vormittags mit Geishauser- Sonde gewonnen, Blut aus der V. jugularis externa sowie Harn per Blasenkathederisierung. Analysiert wurden im Pansensaft der pH-Wert, die Pufferkapazität als Titrationsbilanz über die Titrationsazidität und - alkalität, die Methylenblauprobe sowie die Sedimentaktivitätszeit (SAT), im Harn der pH-Wert, die Netto-Säure-Basen-Ausscheidung (NSBA) sowie der Basen-Säure-Quotient (BSQ) und im Blutserum Glukose, freie Fettsäuren (FFS), Betahydroxybutyrat (BHB), L-Laktat, Cholesterol, Protein, Albumin, Bilirubin, Harnstoff, Kreatinin, Na, K, Cl, Ca, P, Mg, ALP, ASAT, GLDH sowie die CK. Ergebnisse: Zwischen Kühen und Färsen wurden bei den gemessenen Parametern keine gesicherten Unterschiede festgestellt. Es gab auch keine Unterschiede zwischen den Betrieben. Die Pansen-pH-Werte bewegten sich von x= 6,8 (6,43/7,0;1./3. Quartil) zu Beginn des Trockenstehens über minimal x = 6,3 (5,9/6,7) 30 bis 60 d p.p. bis x = 6,6 (6,2/6,8) in der Mittellaktation. Sie lagen alle im physiologischen Bereich. 20 Kühe hatten Pansen-pH-Werte von < 5,8, 6 Kühe von < 5,5 und 21 Kühe von > 7,2. Damit kamen die Kühe der SARA-Definition, bezogen auf das einmalige Auftreten von pH-Werten < 5,8 bei einer Kuh, nahe; bezogen auf alle gemessenen Pansen-pH-Werte betrug der Anteil < 5,8 aber nur 9,8 %. Die Titrationsbilanz war in der Trockensteherperiode ausgeglichen; bei allen drei Kontrollen p.p. bestand ein Basendefizit. Die Pufferkapazität war in der 1. Woche p.p. und in der Frühlaktation vermindert. Panse-pH-Werte und Titrationsbilanz korrelierten sehr eng (r=0,98,p<0,001). Die Methylenblauprobe war a.p. mit x = 3:37 (2:22/4:59) Minuten am längsten, in der Mittellaktation mit 3:01 (2:25/4:30) Minuten am kürzesten und ingesamt physiologisch. Es gab keine signifikanten Unterschiede zwischen den einzelnen Kontollzeiträumen. Die SAT war physiologisch und schwankte zwischen zwei und fünf Minuten ohne signifikante Unterschiede zwischen den Entnahmezeiträumen. Im Harn lagen die NSBA mit x = 70 mmol/l (20/122 = 1./3.Quartil) und der BSQ mit x = 2,2 (1,6/2,8) nur bei den Frischmelkern unter den unteren Grenzwerten und deuteten die Gefahr von SARA an. Der Harn-pH-Wert war mit x = 7,98 (7,7/8,2) physiologisch. Von der Gesamtheit alle NSBA-Werte waren 37% < 83 mmol/l sowie 28,9% < 25 mmol/l; beim BSQ waren es 52,6% < 2,5 sowie 27,4% < 1,5. Die für die NSBA, den BSQ und den Harn-pH-Wert berechneten Sensivitäten und Spezifitäten für einen Pansen-pH-Wert < 5,8 liegen mit 44,8% und 64,5% (NSBA), 55,8% und 47,9% (BSQ) sowie 2,3% und 97% (Harn-pH-Wert) unter den diagnostischen Erfordernissen.Sie können somit keine sicheren Rückschlüsse auf den Pansenzustand geben. Bei den Blutbefunden wurden Kühe mit Pansen-pH-Werten < 5,8 (SARA) und >5,8 gegenüber gestellt. Die Korrelationskoeffizienten, die Sensitivität und die mittels Receiver-Operating-Characteristics Analysen ermittelten Flächen unter der Kurve zwischen Pansen-pH-Wert und den Blutparametern waren niedrig ( p> 0,05). Schlussfolgerung: Hochleistende HF-Kühe haben peripartal nicht zwangsläufig eine SARA. Die Titrationsbilanz ergänzt den Pansensaft-pH-Wert, ist routinemäßig aber nicht nötig. Im Harn liegen die NSBA und BSQ häufiger unter den Grenzwerten und korrelieren nicht gesichert mit dem Pansen-pH-Wert. Auch Blutparameter erlauben keine sichere Aussage über den Pansenzustand. Die Diagnose von SARA muss mit direkter Messung des Pansen-pH-Wertes gestellt werden.

Abstract:
The effect of stage of lactation on milk yield, somatic cell counts, mineral and fatty acid profiles in pasture-based Friesian, Jersey and Friesian × Jersey cows was investigated. Twenty Friesian, twenty Jersey and twenty Friesian × Jersey cows were randomly selected from a dairy herd. A total of 202 milk samples were collected and analysed in three stages of lactation. Genotypic differences were observed in milk yield and fat content. Friesian cows produced the highest yield and lowest fat content whereas the opposite was true for Jersey cows (P<0.01). No significant differences were observed in SCC in the different genotypes, but SCC levels were higher in mid and late lactation (P<0.001). There was no effect (P<0.005) of genotype and stage of lactation interaction on Ca, P, Mg, Na, Mn and Bo concentration. Jersey cows had the least concentration of Fe and Cu in all stages of lactation. Strong positive correlations were observed among Ca and P, Mg and Zn. Aluminium had a strong positive relationship with Bo, Fe, Mn and Zn (P<0.001). Generally, SCC had a weak positive relationship with macro elements but a significant negative relationship with microelements. Yield levels were negatively correlated with Mg, Na, Al, Mn and SCC. Pasture ALA, SFA, n-3, n-6/n-3 and PUFA/MUFA concentration did not differ across the study period. Linoleic acid was highest in the second phase which coincides with mid lactation in cows (P<0.001). Highest moisture content coincided with the least fat free dry matter content in early lactation (P<0.001). Significantly high fat content was observed in late lactation than in early lactation. Highest butyric, caproic, linoleic, n-6 and PUFA were observed for Friesian cows. All other fatty acids ratios were not significantly different among different genotypes. Highest CLA, ALA, LA, SFA, PUFA, n-6, and n-3 and atherogenicity index were observed in early lactation whereas desaturase activity indices were highest in late lactation. Strong positive correlations were observed among milk vaccenic, ALA, LA and CLA concentrations. Inverse relationships were observed between SFA and long chain fatty acids. It can be concluded, it may be of advantage to consume milk from early stage of lactation poses a lower risk to coronary diseases and are much safer to consume.

Abstract:
The objective of this study was to evaluate the variability of growth curves of dairy heifers and estimate genetic parameters. 15066 records taken from birth until 26 months (808 days) on 2754 heifers of Quebec were considered. The pedigree file comprised 10123 animals. The Mixed procedure of SAS with ordinary polynomials was used for simple phenotypic analyses, fitting fixed linear, quadratic and cubic regressions of body weight (in kilograms) on age (in months) as well as random intercept, and random linear and quadratic regressions for each animal. The Wombat program (Meyer, 2007), with Legendre polynomials was used to estimate the genetic parameters by fitting fixed herd-year-season of birth and quartic regression of body weight on age in days, as well as random regressions for quadratic additive genetic and cubic permanent environmental effects. Heritability estimates of body weight ranged from 0.22 at around 70 days to 0.45 at around 210 days. Heritabilities of body weight at birth and 808 days were 0.35 and 0.32, respectively. The additive genetic correlations between body weights at different ages ranged from -0.37 to 1.00. In general, the genetic correlations were higher than the permanent environmental and phenotypic correlations.

Abstract:
The research was performed on 461 first-calf Holstein-Friesian breeds in the area of Vojvodina. The aim of this study was to calculate the basic values and variability of the type using the linear method of cow evaluation. In this research is analyzed 18 linear properties of the type, for which are calculated basic variation-statistical parameters such as: arithmetic mean, standard deviation, coefficients of variation and interval of variation. The average values of linear estimates of the first calf, obtained using statistical parameters, for the characteristics of the carcass ranged from 5.68 to 6.46, for the milk character 6.65, for the foundation from 4.73 to 6.34 and for the udder from 4.07 to 6.17.
