Twinning Beef Cows
gestibility or protein quality of SBM, the urease assay is good for detecting underprocessing and the KOH protein solubility assay is good for detecting overprocessing. A combination of the latter two assays is needed to ensure that SBM has neither been underheated nor overheated. The protein dispersibility index (PDI) assay may be superior to the urease and KOH assays as an indicator of minimu...
متن کاملThe effect of undernutrition of beef cows on blood hormone and metabolite concentrations post partum.
Twelve Hereford Friesian cows were allocated to either a high plane (HP) or a low plane of nutrition (LP) post-partum. HP animals received rations supplying sufficient energy and protein for maintenance plus 10 kg/day milk yield. LP cows were offered approximately 70% of their maintenance needs for 63 days post-partum. Thereafter they received the same ration as the HP animals. A mineral vitami...
متن کاملInfluence of body condition at calving and postpartum nutrition on endocrine function and reproductive performance of primiparous beef cows.
The influences of body condition score (BCS) at calving and postpartum nutrition on endocrine and ovarian functions, and reproductive performance, were determined by randomly allocating thin (mean BCS = 4.4 +/- 0.1) or moderate condition (mean BCS = 5.1 +/- 0.1) Angus x Hereford primiparous cows to receive one of two nutritional treatments after calving. Cows were fed to gain either 0.45 kg/d (...
متن کاملInfluence of source and amount of dietary protein on performance, blood metabolites, and reproductive function of primiparous beef cows.
Forty Angus x Hereford 2-yr-old primiparous cows (358 kg) were used to determine the effects of source and amount of CP on performance, reproductive function, and metabolic status of suckled primiparous cows. A 2 x 2 factorial treatment arrangement was used; cows received either 100 or 150% of NRC recommendations for CP in diets that contained either soybean meal (low escape = L) or corn gluten...
متن کاملOptimising reproductive performance of beef cows and replacement heifers.
A reproductively efficient beef cow herd is fundamental to meeting the protein and specifically, red meat demand of an ever increasing global population. However, attaining a high level of reproductive efficiency is underpinned by producers being cognisant of and achieving many key targets throughout the production cycle and requires significant technical competency. The lifetime productivity o...
