Summary:An abstract of the study by Reis et al evaluating the effects of either nutritional restriction or intake of concentrate feedstuffs before beginning the adaptation period on rumen morphometrics and rumenitis of Nellore cattle conducted at Sao Paulo State University feedlot, Dracena campus, Brazil, is discussed. The experiment was designed as a completely randomized block, replicated 8 times (4 animals/pen), in which ninety-six 22-mo-old yearling Nellore bulls were fed in 24 pens according to the treatments. The results of the study suggest that cattle should be submitted to nutritional restriction prior to a period of feeding high-concentrate diets because it led to greater rumen epithelium development.
