Previous research indicates cribbing behavior in horses increases when horses were fed concentrate meals. This study used 10 mature cribbing geldings to investigate effects of ad libitum concentrate feeding on cribbing ...
Effect of Diet Complexity and Dietary Fish Peptide Supplementation on Weanling Pigs
(2020-07-08)
Young pigs are subjected to various stressors at weaning, and providing a highly palatable and digestible diet is, obviously, important in preventing or alleviating growth check soon after weaning and also optimizing growth ...
Effect of Diet Complexity, Multi-enzyme Complexes, Essential Oils, and Benzoic Acid on Weanling Pigs
(2016-05-05)
The objective of this study was to investigate the effect of supplementing a simple corn-soybean meal (SBM) diet with multi-enzyme complexes, essential oils, and benzoic acid on growth performance, serum metabolite profile, ...
Effect of Dietary Fish Peptide and Enzyme Supplementation on Weanling Pigs
(2021-04-21)
A corn-soy diet is the gold standard for feeding pigs, however, such a diet may not be appropriate for weanling pigs. Weanling pigs are subjected to various stressors at weaning, and their digestive system is immature or ...
The Effect of Early Dietary Amino Acid Restrictions on Serum Metabolites in Pigs Selected for Lean Growth Efficiency
(2005-12-15)
Thirty-two select line and 32 control line pigs (average, 20 kg) were used in each of the two experiments to assess the effect of dietary amino acid restrictions during the grower phase on serum metabolites. In Exp. 1, 16 ...
The Effect of Pharmacological and Dietary Modulators of Lipid Metabolism on Gene Expresion in a Porcine Model
(2006-12-15)
Modifying the size and/or carcass distribution of adipose tissue in meat producing animals by nutritional and pharmacological means has long been of interest to animal scientists. In pigs, as in other meat animals, a more ...
Effect of the Degree and Duration of Early Dietary Amino Acid Restrictions on Growth Performance, Carcass Traits, and Serum Metabolites of Pigs, and Physical and Sensory Characteristics of Pork
(2008-12-15)
The objective of this study was to investigate the effect of the degree and duration of early dietary amino acid restrictions on growth performance, serum metabolites, internal organ weights, and carcass traits of pigs, ...
Effects of Acetic Acid on Dark Cutting Beef
(2017-01-11)
An experiment was conducted to evaluate the effects of an acetic acid product e(Lm)inate ® V distributed by Hawkins, Inc. on meat quality attributes of dark cutting beef strip loins. Three treatment application groups: ...
Effects of Animal Fat, Flaxseed Oil, and Vitamin E on Growth Performance and Metabolic Profile of Finisher Pigs, Physical and Organoleptic Characteristics of Pork, and Gene Expression in Adipose and Muscle Tissues of Finisher Pigs
(2017-12-01)
Producing high-quality pork is an integral part of successful and sustainable pig production. Lipid content and composition is central to the nutritional value and eating quality of pork. The objective of this project was ...
The Effects of Days on Feed and Ractopamine HCL Administration on Growth and Carcass Traits of Yearling Heifers
(2011-08-04)
Heifers comprise 30% of the total beef animals slaughtered in the United States yearly.
However, heifers are less efficient and have lighter HCW than steers which affects the profitability of heifers. Beta adrenergic ...
