TL;DR: The energy and protein requirements of non-descript breed hair lambs reared under Brazilian semiarid conditions were determined and the NEg increased and the NPg decreased with the increase in body weight of NDB lambs.
Journal ArticleDOI
Influence of feeding pattern on the biological efficiency of high-yielding dairy cows
TL;DR: Calculated efficiencies of utilization of metabolizable energy for milk production (Klo) were variable throughout lactation and lower than the currently accepted standards.

Walking Stress Influence on Livestock Production
TL;DR: The significant changes in physiological responses, adrenal and thyroid hormone concentrations after subjecting the livestock species to walking stress shows that they are capable to adapt to long-distance walking and adrenaland thyroid gland hormones play a significant role in such adaptation.
Journal ArticleDOI
Estimating ruminal nitrogen-to-energy balance with in situ disappearance data.
TL;DR: The ruminally degraded N:ruminally degraded OM ratio seems to be a useful tool for predicting apparent ruminal N digestion and managing the nutrition of forage-fed cattle.
Journal ArticleDOI
A survey of the phosphorus content of pastures and the serum inorganic phosphorus content of dairy cows.
TL;DR: Serum inorganic phosphorus concentration of 20 cows in each of ten factory supply dairy herds was assessed at monthly or two-monthly intervals during the 198243 lactation and the possibility of increasing dairy production with P supplementation in spring is discussed.
