Breeding and Genetics: Dairy Cattle Breeding I
Humans obtain a number of products from animals. These include food, clothing, medical materials, companionship and research knowledge to name a few. A valued ethic contends that it is inappropriate for one to treat another as a means to an end. In short, it is wrong to treat another as simply a product. Historically, non-human beings have not been included as “others” and thus their treatment ...
متن کاملBreeding and Genetics: Dairy Cattle
Protein-damaging stresses, including heat shock, cold, altered pH and oxygen deprivation induce the expression of a subgroup of molecular chaperones, called heat shock proteins (Hsp), which consist of several protein families designated by their molecular weight, such as the Hsp90, Hsp70, Hsp60, and the small Hsp (sHsp) families. Small heat shock proteins (sHsp) with a molecular mass of 15–30 k...

last rib backfat thickness, broken vertebrae, or scores for stomach ulcers (P > 0.21). Also, deletions of VTM premixes did not affect these same measurements (P > 0.22). However, RAC decreased (P < 0.01) backfat thickness by 8% and tended to decrease scores for stomach ulcers (P < 0.06). In conclusion, there were no interactions to suggest that the effects of RAC on growth performance and carca...
متن کاملBreeding and Genetics: Dairy Crossbreeding and Breeding Objectives
First-parity Holstein (H), Normande-Holstein (NxH) crossbred, Montbeliarde-Holstein (MxH) crossbred and Scandinavian-Holstein (SxH) crossbred cows calving from June 2001 to December 2003 were compared for dystocia and stillbirths from seven California herds. Dystocia scores ranging from 1 (no assistance) to 5 (hard pull) and stillbirths (1 for alive and 0 for dead) were recorded for 1695 Holste...
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...
