Comparative Analysis of Maternal Colostrum and Colostrum Replacer Effects on Immunity, Growth, and Health of Japanese Black Calves.

Maternal colostrum (MC) is an important source of nutrients and immune factors for newborn calves. However, when colostrum is unavailable or of poor quality, a colostrum replacer (CR) may be a suitable alternative to MC. As stock-raising farmers must make informed decisions about colostrum feeding management, this study was conducted to determine the effect of feeding MC versus CR on the promotion of immunological status, growth, and health in pre-weaned Japanese black (JB) calves.

Different doses of tannin reflect a double-edged impact on broiler chicken immunity.

Tannin is one of the most common phytochemical secondary phenolic metabolites, which is widely distributed in various plant production systems. Dietary intake of tannin can exert different actions on the immune system. The aim of this study was to evaluate the influence of different concentrations on broiler chicken immunity.
