Effects of palm fat powder and coated folic acid on growth performance, ruminal fermentation, nutrient digestibility and hepatic fat accumulation of Holstein dairy bulls

This study evaluated the effects of palm fat powder (PFP) and coated folic acid (CFA) on growth performance, ruminal fermentation, nutrient digestibility, microbial enzyme activity, microflora, hepatic lipid content and gene expression in dairy bulls. Forty-eight Chinese Holstein bulls ((362±12.4) days of age and (483±27.1) kg of body weight (BW)) were assigned to four groups in a completely randomized design with a 2×2 factorial arrangements. …
