Graduate Theses and Dissertations
Lactate dehydrogenase (LDH) catalyzes the conversion of the pyruvate to lactate (forward) or lactate to pyruvate (reverse) in the last step of glycolysis. Objectives were to document the effects of LDH haplotypes and its SNPs, found in the promoter and coding sequence site, and body condition on beef cow production. Four single nucleotide polymorphisms (SNP) of LDH-B and Five single nucleotide polymorphisms of LDH-A were detected. Eight haplotypes of LDH-B were assigned with the same order of SNPs: G-348A, A-261G, N-222D, and C541A and four haplotypes of LDH-A were assigned with the same order of SNPs: T-327G, D-263C, G390A, A406G, …

Increased BCS at calving due to nutritional manipulation during the prepartum period resulted in greater mobilization of body fat after calving, regardless of plane of nutrition during the last 60 d of gestation. Although fatter cows were shown to have greater mobilization of reserves during the postpartum period, they maintained greater BCS at all points from calving to weaning compared to cows calving with fewer reserves at calving. A unique finding of this experiment was that the variation in BCS at calving was positively associated with BCS loss for cows fed to accrete BC during the prepartum period but was …
