Tremendous metabolic and endocrine adjustments must be made as dairy cows move from late gestation to early lactation. Requirements for glucose metabolizable energy increase two- threefold 21 d before after parturition. The liver adapt quickly provide the increased needed support high milk production, process flood of nonesterified fatty acids taken up extensive mobilization adipose triglycerides. While end results these adaptations are well known, much less is known about cellular molecular...
New laboratory and animal sampling methods data have been generated over the last 10 yr that had potential to improve predictions for energy, protein, AA supply requirements in Cornell Net Carbohydrate Protein System (CNCPS). The objectives of this study were describe updates CNCPS evaluate model performance against both literature on-farm data. changes feed library significant are reported a separate manuscript. Degradation rates protein carbohydrate fractions adjusted according new...
The authors have developed a method to induce chronic cerebral vasospasm after subarachnoid hemorrhage (SAH) in monkeys. With microsurgical techniques, 33 monkeys had frontotemporal craniectomy and unilateral opening of the cisterns. Cerebrospinal fluid was drained fresh hematoma, obtained from an average 7 ml autologous blood, carefully placed against major arteries anterior circulation on one side. 30 studied for 14 days SAH were allocated randomly two treatment groups 15: group received...
The transition period is defined as the 6–8 weeks encompassing late pregnancy and early lactation, involving coordinated changes across multiple tissues an enormous increase in nutrient requirements. Failure to successfully can result reduced DM intake, milk production, delayed oestrus, failure conceive increased incidence of metabolic infectious diseases, many which are inter-related. Modern technologies have enabled measurement transcriptional genes involved biochemical pathways period,...
Forty-eight multiparous Holstein cows were fed treatments consisting of either 0, 45, 60, or 75 g/d a rumen-protected choline (RPC) source in completely randomized design from 21 d before expected calving to 63 postpartum determine whether supplementation the diet would affect hepatic fatty acid and glucose metabolism, key metabolites plasma, cow performance. Dry matter intake (DMI), milk yield, body condition score, weights (BW) similar for receiving four treatments. Feeding RPC tended...
Short-term studies (< 5 d) involving abomasal infusion of a mixture CLA isomers or pure trans-10, cis-12 have demonstrated that supplements conjugated linoleic acids (CLA) reduce milk fat synthesis during established lactation in dairy cows. Our objective was to assess longer term effects supplementation using dietary supplement rumen-protected CLA. Thirty Holstein cows were blocked by parity and received either Ca-salts palm oil fatty (control) plus (CLA treatment). Supplements provided...
✓ Chronic cerebral vasospasm was induced in monkeys by placement of an autologous blood clot after the basal cisterns had been opened over arteries circle Willis on one side. The experimental protocol detailed Part 1 this paper. Twenty 30 studied from both groups (one receiving placebo and other nimodipine) underwent fixation (Day 14) at controlled pressure intra-arterial perfusion. base brain were light microscopy scanning (SEM) transmission electron (TEM). Cerebral angiography Day 7 showed...
Trace minerals have critical roles in the key interrelated systems of immune function, oxidative metabolism, and energy metabolism ruminants. To date, primary trace elements interest diets for dairy cattle included Zn, Cu, Mn, Se although data also support potentially important Cr, Co, Fe diets. such as are essential with classically defined components antioxidant enzymes proteins. Available evidence indicates that these can modulate aspects function cattle, particularly during transition...
