Economic evaluation of genomic breeding programs.
The objective of this study was to compare a conventional dairy cattle breeding program characterized by a progeny testing scheme with different scenarios of genomic breeding programs. The ultimate economic evaluation criterion was discounted profit reflecting discounted returns minus discounted costs per cow in a balanced breeding goal of production and functionality. A deterministic approach ...

متن کاملApplication of myostatin in sheep breeding programs: A review
Myostatin or growth and differentiation factor 8 (GDF8), has been known as the factor causing double muscling phenotypes in which a series of mutations make the myostatin protein inactive, hence disabling it to regulate the deposition of muscle fibre. This phenotype happens with high frequency in a breed of sheep known as the Texel. Quantitative trait loci (QTL) studies show that a portion of t...
متن کاملBreeding and Genetics: Dairy Genetic Evaluation
Due to the lower DMI, the IH200 heifers had lighter final weight and lower ADG on a live basis (P<.01) than the IHFH heifers, but these differences were reduced on a carcass-adjusted basis. The IH200 heifers had significantly improved feed conversion compared to FH and R200 (P = 0.01) and tended to have better feed conversion than IHFH (P = 0.14) on a carcass-adjusted basis. The IH200 heifers h...
متن کاملSpatial Characterization of Smallholder Zones in Uganda
The critical first step for the regionalization analysis was to use the description of the Kenya smallholder dairy environments and extrapolate those conditions over Uganda and Tanzania. This kind of evaluation of other countries would not have been possible using the traditional Jaetzold and Schmidt agro-ecological zone map as their zonation scheme was designed specifically for Kenya and was n...
