Reproductive effects of feeding gossypol and vitamin E to bulls.
An experiment was conducted to determine the effects of long-term feeding of cottonseed meal on the reproductive traits of Holstein bulls. Holstein bulls approximately 6 mo of age were placed on the following treatments: 1) soybean meal + corn (CON); 2) cottonseed meal + corn (GOS); and 3) cottonseed meal + 4,000 IU vitamin E x bull(-1) x d(-1) (G+4E). The GOS and G+4E diets were formulated to ...
متن کاملTissue distribution of gossypol enantiomers in broilers fed various cottonseed meals.
Plasma and tissue concentrations of total, (+)- and (-)-gossypol were determined in broilers fed cottonseed meals (CSM) from eight oil mills (five expander solvent, two expeller, and one direct solvent). Free gossypol in the meals ranged from 0.033 to 0.180%, and total gossypol ranged from 0.974 to 1.459%. The (+)-enantiomer of gossypol varied from 53.8 to 61.3% of total gossypol. Eight CSM die...

متن کاملEffect of bound gossypol and amino acid supplementation of glandless cottonseed meal on the growth of weanling rats.
After a feeding study comparing the growth response of rats fed a 10% protein diet of glandless cottonseed meal with the same meal to which gossypol had been bound showed the latter produced significantly lower weight gains, two experiments were conducted in which the diets were supplemented with single amino acids. The amino acids were either L-lysine, L-isoleucine, L-valine or L-threonine and...

In order to investigating the effect of exogenous enzymes on growth performance, blood and rumen parametes,18 Brown Swiss male bulls were used in an balanced completely randomized design. The experimental diets were: 1) basal diet (control), 2) basal diet containing 0.50 g enzymatic mixture /kg DM of diet and 3) basal diet containing 0.75g enzymatic mixture /kg DM of diet. The bulls were fed to...
