Performance and carcass quality of steers supplemented with zinc oxide or zinc methionine.
Forty-five Angus steers (avg initial wt 330 kg) were individually fed for 112 d to assess the value of supplemental Zn and source on performance and carcass quality. Steers had ad libitum access to a control diet (81 ppm Zn) of 33% whole corn, 33% ground milo, 15% cottonseed hulls and 13% cottonseed meal, or this control diet with 360 mg Zn/d added from either zinc methionine or zinc oxide. Ste...
متن کاملInfluence of Inorganic and Organic Selenium Sources on Broiler Performance and Meat Quality
An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...

Carcass and commercial cuts yield in broilers of different ages fed diets supplemented with probiotics
In this study, the carcass and commercial cuts weights and yields in broilers of different ages fed diets supplemented with probiotics were determined. A total of 336 male broiler chicks (Ross-308) were randomly allocated into three treatment groups (P0, P1 and P2). A basal diet (P0), basal diet plus 0.01% (P1) and 0.02% (P2) probiotic (Saccharomyces cerevisiae, 4x10 8 cfu g -1 ) were offered t...
