自由采食乳替代品饲喂的犊牛在断奶过渡期(第3周和第6周)的血浆胆酸动态变化规律
M H Ghaffari,A Stoschus,L E Diesing et al.
M H Ghaffari et al.
Elevated milk replacer (MR) feeding supports early-life growth in dairy calves but may increase the biological complexity of weaning by shifting calves from milk-derived intestinal nutrient absorption to solid-feed-dependent gastrointestina...
Impact of colostrum processing on metabolic and endocrine parameters during early postnatal life in calves [0.03%]
乳头处理对犊牛出生后早期代谢和内分泌参数的影响
I Weber,M A E von Riedheim,H Erkinger et al.
I Weber et al.
Colostrum feeding is essential for calf immunity, nutrition, and neonatal survival. To ensure availability when maternal supply is insufficient, various storage and preservation methods have been adopted in dairy management. The objective o...
