| ABSTRACT Cottonseed coproducts contain gossypol which can have specific effects upon the male reproductive system. We evaluated the reproductive development of male lambs close to puberty fed on three cotton coproducts. Twenty-four 5-month old male lambs received four diets: 20 % of dry matter intake of whole cottonseed (WCS), high oil cottonseed meal (CSC), cottonseed meal (CSM), and a control group (CTL) without any cottonseed coproducts. Free gossypol intake was 16.32, 6.98, 5.47 and 0 mg kg−1 BW−1 d−1 for WCS, CSC, CSM and CTL, respectively. Every 15 days, the animals were weighted and serum and semen samples were collected. After 95 days, testis samples were collected for analysis under light and transmission electron microscopes. The CTL group had... |

| ABSTRACT: Gossypol easily pairs with lysine side chains and enzymes involved in the cellular growth process. The effect of gossypol (a compound present in cotton co-products) in ruminant metabolism and meat quality is not yet clear. This study was undertaken in order to evaluate the effects of cotton co-products in lamb muscle proteome. Twenty-four Santa Inês ram lambs, 5-months old (20.6 ± 1.9 kg), were randomly assigned to four treatments: control (without cottonseed), whole cottonseed, cottonseed meal and high oil cottonseed meal. At 95 days into the experiment, lambs were slaughtered and samples from Longissimus dorsi were collected. Proteins were extracted and analyzed by 2-D electrophoresis. Spots showing a significant effect from the treatment (the... |
