| There is a paucity of information in the literature on body composition changes in Nellore cattle and its crosses, mainly on heifers and intact males. Ultrasound is a useful, low cost tool to easily obtain this information, with minimal animal stress. Effects of sex and days on feed on live weight (LW) and ultrasound Longissimus muscle area (ULMA) and subcutaneous fat thickness (UFAT) measurements were evaluated in F1 Piedmont <FONT FACE=Symbol>´</FONT> Nelore, 27 heifers (HF) and 27 intact males (IM). HF and IM had an initial LW of 256 ± 5.6 and 265 ± 5.6 kg, respectively, and were fed a diet containing 77% TDN for 131 days. LW, ULMA, and UFAT were evaluated at 28-d intervals. Interactions between sex and days on feed were found for all traits... |
