dc.descriptionThis study investigated the effects of different by products used as feedstuffs to replace ground corn for supplementing Holstein dairy cows rotationally grazing intensively managed elephant grass. Five experiments were conducted to evaluate various levels of pelleted citrus pulp (PCP), corn gluten feed (CGF), whole cottonseed (WCS), wheat middlings (WHM), and soybean hulls (SBH) as alternatives to ground corn in iso proteic and iso energetic supplements. The experiments followed a Latin square design and assessed blood and performance parameters such as milk yield (MY) and milk composition. Blood parameters were not affected (p > 0.05) by any by products. The inclusion of PCP, CGF and SBH up to 75 %, and WHM up to 50 % in place of corn did not affect (p > 0.05) either MY or milk composition. However, replacing the inclusion of ground corn at the level of 75 % of WCS resulted in a significant reduction (p < 0.05) in yields of milk, 3.5 % fat corrected milk, protein, and milk solids, along with an increase (p < 0.05) in milk urea nitrogen. Results obtained suggest that the replacement of ground corn by PCP, CGF and SBH up to 75 % and WHM and WCS up to 50 % in the supplement have no adverse short term effects on MY and composition in Holstein cows grazing intensively managed elephant grass.
