Production Traits

Crossbreeding of Holstein cattle with bulls of other breeds has garnered increasing interest with respect to efforts to improve performance traits and to decrease problems with fertility and health. Therefore, the objective of this study was to compare the effects of the fatty acid synthase (FASN) gene on milk production traits and fatty acid composition of Simmental and first-generation Holstein × Simmental crossbred cows. A total of 105 cows (72 Simmental and 33 crossbred Holstein) were genotyped using the PCR-RFLP method and their fatty acid profiles were analysed. The crossbred Holstein cows with diplotype TW/AR had significantly higher fat content and yield compared to the purebred Simmental cows of the same diplotype. The Holstein × Simmental cows with the diplotype AR/AR were also characterised by significantly lower content of C16:0 and saturated fatty acids, but higher C18:1n9, monounsaturated fatty acid and monounsaturated fatty acid/saturated fatty acid content compared to the same diplotype of the Simmental cattle. These results indicate that with accurate breeding plans, crossbreeding Holstein cows with Simmental bulls could be directed towards a more desirable fatty acid composition of milk and dairy products.

Abstract Background:Cobb broilers (COBB) have been heavily selected for their production performance in the past several decades, while the Athens Canadian Random Bred (ACRB) chickens, a meat-type breed, has been kept as a non-selected control strain. The purpose of this study was to compare these two lines of chickens at late-embryonic development and identify the molecular markers and fatty acid profiles underlining their differences in growth performance due to selection. Results: COBB had higher egg weight, embryo weight, and breast and fat ratio. The gene expression in the liver showed an interaction between age and breed on FASN (fatty acid synthase) expression with the highest level in COBB at E18. ACRB had higher Apo-B (apolipoprotein B) and MTTP (microsomal triglyceride transfer protein) expression, but lower SREBP-1(regulatory element-binding protein 1) expression compared to COBB. No difference was found in myogenesis gene expression in the muscle between two breeds. For the fatty acid composition, muscle was largely affected by both breed and age. Yolk and liver were affected mainly by breed and age, respectively. Constant interaction effects in docosahexaenoic acid (DHA), indicating the highest level in all the tested tissues of ACRB at E14 and the constant main effects with higher myristic, palmitic and gondoic, but lower linolenic acid in the liver and yolk of COBB compared to in those of ACRB. At last, fat accumulation in the liver had no obvious difference between the breeds but was higher when embryo was older. Conclusions: Broiler breed affects egg, embryo and tissue weight, as well as FA composition in initial egg yolk and throughout the embryonic development. The highest docosahexaenoic percentage was observed in ACRB, indicating that genetic selection may result in fatty acid profile changes in chicken tissues and eggs.
