The objective of this study was to evaluate the effect of three levels of crude cottonseed oil on performance, organ weights, and blood parameters of growing broilers. Carcass and cut yields after 33 and 42 days of age and the economic viability of the diets were also evaluated. Male broilers of the Ross line were distributed in a completely randomized design, in a 4 × 2 factorial arrangement (0, 2, 4, and 6% inclusion of cottonseed oil, with and without […]

This work was carried out with the objective to evaluate the effects of different levels (0.0 20.0, 30.0 and 40.0%) of whole cottonseed (Gossypium hirsutum L.) of the diet (% DM) on carcass characteristics, cut yields and carcass muscularity of feedlot Santa Inez sheep. Twenty-four sheep with average initial and final body weight of 19.0 and 32,2kg, respectively, and allotted to a completely randomized design, with four diets and six replications. No effect was observed for the inclusion of whole […]

This work was carried out with the objective to evaluate the effects of different levels (0.0 20.0, 30.0 and 40.0%) of whole cottonseed (Gossypium hirsutum L.) of the diet (% DM) on performance and nutrient digestibilities of feedlot Santa Inez sheep. Twenty-four sheep with average initial and final body weight of 19.0 and 32.2 kg, respectively, and allotted to a completely randomized design, with four diets and six replications. The dry matter intake in kg/day, %BW and g/kg0.75 was not […]

A trial was carried out to evaluate the effects of increasing levels (0, 8 and 12%) of cottonseed meal 36% (CM36) and three inclusion levels (0, 20, and 40 g/100 kg) of ferrous sulfate – FeSO4 (12% of CM diets) on the performance, plasma urea nitrogen (PUN) and hematological values of starting pigs (15-30 kg). Eighty pigs, barrows and females, averaging initial body weight of 14.81 ± 1.72 kg were allotted to a complete randomized block design with five treatments […]

This experiment was conducted to evaluate the effect of cottonseed meal and cotton seed flour on the reproductive behavior and on the testis activity of Nile tilapia broodstock. Twenty-five fishes were fed diets containing 0, 2, 4 and 6% ground cottonseed flour and 24% cottonseed meal (CSM). The reproductive behavior of the fishes was daily observed and the nest construction, courtship and spawning were evaluated. At 90 days, the males gonads were microscopically evaluated. The control group (soybean meal) showed […]
