Abstract:

This paper describes a genetic analysis of 20000 weighings from 1980-1988 on the progeny of more than 210 sires from three straightbred Brahman and one crossbred herd (Brahman or SahiwalxBritish breeds) in the Australian tropics. 200 day weight averaged 192 kg, very slightly less than 200 day weight in temperate Australia with similar phenotypic variance of 520 kg2. Mean 550, 700, and 900 day weights of 310, 350 and 450 kg and phenotypic variances of 800, 800 and 1485 kg2 were lower than in temperate regions at the same ages.

Abstract:

Saleable beef yields from the carcasses of 38 Brahman crossbred bullocks, 42 Brahman crossbred females, 75 Hereford bullocks and 35 Hereford females were recorded in the boning room of an export abattoir. Regressions of saleable beef yield on 12th rib fat thickness and on rump P8 fat thickness were examined for breed and sex effects. Linear regression analysis showed that rump P8 fat thickness and 12th rib fat thickness predicted percentage yield of saleable beef with prediction errors at the mean (of the predictor variables) of 2.3 and 2.1 respectively.

Abstract:

The increasing need for effective analytical tools to evaluate beef quality has prompted the development of new procedures to improve the animal sector’s performance.

The findings demonstrated that TN beef was lighter and tougher than other beef. Beef odor was stronger in BT. In addition, CB beef was the most tender and had the highest intramuscular fat content.

Abstract Horn flies are the most common summer pests of cattle, leading to substantial economic losses due to impaired production and decreased animal welfare. Genetic and non-genetic factors have been reported to influence cattle susceptibility to horn flies. However, the wide range of heritability estimates, and few identified genomic regions associated with cattle resistance to horn fly may be due to subjective assessment in collecting the fly load phenotype and the small size of the population assessed.

Abstract:

Sinh sản và sản xuất thịt là những tính trạng kinh tế quan trọng trong sản xuất chăn nuôi. Để cải thiện di truyền những tính trạng này, chỉ thị phân tử đã được ứng dụng rộng rãi ở nhiều nước có hệ thống chăn nuôi phát triển. Những nghiên cứu gần đây cho rằng gen RNF212 và NCAPG liên quan đến khả năng sinh sản và sức sản xuất thịt ở động vật có vú. Trong đó, đột biến thay thế nucleotide đơn C>T trên gen RNF212 được biết làm gia tăng tỷ lệ tái tổ hợp giảm phân ở bò. Hơn nữa, tỷ lệ tái tổ hợp giảm phân tương quan thuận với hiệu quả sinh sản nên đột biến này có thể là chỉ thị quan trọng liên qu

Abstract Thermoregulation is important for beef cattle but tends to be negatively correlated with production traits. The objective of this study was to determine the variation in core body temperature and to estimate genetic parameters of skin traits in Angus, Brahman, and different levels of crossbred heifers (n = 337) reared in hot and humid conditions. Core body temperature was recorded as vaginal temperature every 15 minutes for 5 consecutive days.

Reduced tolerance to chilling and cryotolerance of oocytes and embryos has been associated with greater cytoplasmic lipids. Previous studies in the cow have demonstrated nutrition-induced modification of follicular components. trans-10, cis-12 conjugated linoleic acid (CLA) was identified as a potent inhibitor of milk fat synthesis in lactating cows, and inclusion of CLA in bovine embryo culture medium reduced embryo lipid content and improved post-thaw embryo survival. Dietary supplementation of cows with CLA could alter oocyte fatty acid metabolism, oocyte lipid composition, and embryo cryot
