Research to date has suggested that access to forage before weaning can limit rumen
development in calves, but no research has yet addressed the role of forage for calves fed …

This study aimed to evaluate whether probiotics, phytobiotics or their combination as feed
additives, given during the preweaning period to neonatal calves, can enhance calf health …

Ruminal parameters, rumen development, nutrient digestibilities, and N utilization were
estimated in Holstein calves fed starch from different sources. Ground corn, ground barley …

The objective of the study was to determine the effect of different liquid feeds on calf small
intestine and rumen development. Twenty-one bull calves (5±1 d old) were randomly …

In the artificial rearing of dairy calves, the same feeding plan is applied to all animals during
the milk-feeding period, with individual differences attributable to development or health …

The determination of the ruminal degradability rate of feeds, mainly starch and crude protein,
is one of the most common methods to evaluate the nutritional value of ruminant feed. The …

The objective of this study was to investigate the effects of grain sources and forage
