The effect of feed intake containing whole cottonseed on blood parameters of Nellore bulls

Abstract

The aim of this study was to evaluate the effect of diets containing whole cottonseed (WC) on blood biochemical parameters of bulls. Thirty bulls with 30±6 months and 382.7±28.4kg were kept in feedlot (85 days) and fed the following WC levels: 0, 2. 22, 4.44, 6.66, 8.88

Development and Evaluation of an Extruded Balanced Food for Sheep Based on Cottonseed Meal (Gossypium hirsutum)

“…It has been reported that the moisture content during extrusion helps the destruction of some aflatoxins, in addition to a high moisture concentration in the extruded product increases the loss of toxic factors [6]. According to Gomes et al [4], cotton flour contains 0.1-0.4% free gossypol. The processing of cotton flour, especially at high temperatures, favors the reduction of gossypol and it has been suggested that diets containing up to 200 mg of free gossypol are safe for ruminants, while 400 mg is the limit for considering it toxic, and, at levels greater than 800 mg, causes death [4].…”

“…In addition to animal toxicity, it has been reported to have anticancer, antiviral, and male infertility effects [2]. Ruminants can digest gossypol better than monogastric animals, so cottonseed meal is only used up to 23% in ruminant feed, due to the presence of gossypol, resulting in limited use [4]. Preventive procedures to limit the toxicity of gossypol involve the treatment of the cottonseed product to reduce the concentration of free gossypol with the most common treatment: thermal processing.…”
