the aims of the present study was to evaluate the level of aflatoxin b1 (afb1) in feedstuffs (corn silage, corn, dried alfalfa, cottonseed meal, cottonseed, soybean meal, canola meal, barley, wheat bran, concentrate, sugar beet pulp and wheat straw) that collected from dairy herds in khorasan razavi province that classified according to milk yield in very high (>10000 kg/day), high (5000-10000 ...

Coagulation is an important unit process in water treatment to decrease suspended and dissolved contaminants cottonseed meal derived proteins can be effective biocoagulants.

For many years, commercial-grade hexane has been the preferred solvent for extracting oil from cottonseed. Recent environmental and health concerns about hexane may limit the use of this solvent; therefore, the need for a replacement solvent has become an important issue. Heptane is similar to hexane, but does not have the environmental and health concerns associated with the latter. On a labor...

In experiment 1, 24 midlactation, multiparous Holstein cows were used in six 4 x 4 Latin squares to evaluate extruded-expelled cottonseed (EEC) as a source of ruminally undegradable protein (RUP). Diets were formulated to contain: 16% crude protein (CP), 35% RUP (SBM16); 18% CP, 35% RUP (SBM18); 16% CP, 40% RUP using EEC (EC16); and 16% CP, 40% RUP using a fishmeal-blood meal blend (FBM16). Mil...

Cotten, Bradley M. M.S., Purdue University, May 2015. Investigating the amino acid digestibility of alternative protein sources and determining the impact of dietary fiber on energy, nitrogen, and amino acid digestibility in growing pigs. Major Professor: Olayiwola Adeola. Three experiments were designed to quantify the nitrogen (N) and amino acid (AA) digestibility of various protein sources f...

Aflatoxins are potent mycotoxins produced by fungi in Aspergillus section flavi. The toxic effect of aflatoxins on humans and other animals is well known (7); thus, many countries regulate the quantity of aflatoxins allowed in foods and feeds (17). Aspergillus flavus Link:Fr. infects many oilseed crops and is frequently, as with cottonseed, the primary cause of aflatoxin contamination (13). Whe...

Fifteen different vegetable protein sources found in Pakistan were evaluated for ruminal degradability characteristics through in situ procedure using rumen fistulated Nili-Ravi buffalo steer. Samples of soybean meal, corn gluten meal 60%, maize gluten feed, guar meal, sunflower meal, rapeseed meal, rapeseed cake, canola meal, cottonseed cake, cottonseed meal, coconut cake, coconut meal, palm k...

Despite the potential for gossypol toxicosis (particularly in pre-ruminants) and risk factors associated with impaired fertility in bulls, cottonseed products offer a safe alternative feed for cattle producers when fed at recommended levels. Beef producers seeking to lower production costs should consider using cotton byproducts in their feeding programs. If carefully incorporated, cotton bypro...
