A ESTRA (" T Hrotein is an expensive ingredient of dairy cattle feeds. Overfeeding of protein
contributes to environmental pollution and higher feed costs. Although, high dietary protein …

Reproduction in dairy cattle is negatively affected by a negative energy balance (NEB), a
combination of the deposition or mobilisation of fat and protein. The mode of action of NEB …

The objective of this observational study was to identify factors associated with estrous
duration (DU) and intensity measured as the peak of activity (PA) change and subsequent …

Urine and fecal excretions from cattle contribute to global nitrogen (N) emissions. The milk
urea nitrogen (MUN) concentration in dairy cows is positively correlated with urinary urea N …

The considerable increase in the production capacity of individual cows owing to both
selective breeding and innovations in the dairy sector has posed challenges to management …

The main objectives of this study were to estimate genetic parameters for milk urea nitrogen
(MUN) in Holstein cattle and to conduct a single-step (ss) GWAS to identify candidate genes …

The reader is encouraged to refer to articles that deal with nutrition and reproduction and
ovulation in postpartum cows [1–9]. Nutrition influences reproduction in mammals via …

Three experiments were conducted to investigate the effects of polyurethane coated urea on
in vitro ruminal fermentation, ammonia release dynamics and lactating performance of …

Milk urea content is receiving growing interest from science and industry as a tool to infer the
protein adequacy of dairy cows' diets, nitrogen excretion and its environmental impact, and …

Nutrition markedly affects sheep milk composition and can be used to improve its suitability
as food for humans. The effect of nutrition on sheep milk fat quality has been covered by …
