Effect of a combination of diethylstilbestrol and methyltestosterone, sex and dietary protein level on performance and carcass characteristics of finishing swine.
N U T R I T I O N can markedly affect carcass leanness. There is evidence, recently reviewed by Wallace et al. (1966), that dietary restriction of either energy or total diet will bring about increased carcass leanness. Several workers have also reported improvement in carcass desirability with increasing levels of dietary protein or lysine (Ashton et al., 1955; Cahilly et al., 1963; Wagner et ...
متن کاملEffects of Dietary Conjugated Linoleic Acid and n-3 Fatty Acids on the Performance, Carcass Traits and Small Intestinal Morphology of Broiler Chickens
An experiment was conducted on broiler chickens to study the effects of conjugated linoleic acid (CLA), fish oil, both at 7% of the diet, or their mixtures at 3.5% of the diet, on the performance, carcass traits and intestinal morphology of broiler chickens. The chicks fed with 7% fish oil or 7% CLA diets, were found to have an inferior weight gain in grower and finisher phases, respectively. A...
متن کاملEffects of Chicory Powder and Butyric Acid Combination on Performance, Carcass Traits and some Blood Parameters in Broiler Chickens
The objective of this study was to determine the effect of different levels of chicory root and stem powder (CRSP) and butyric acid (BA) combination on the performance, carcass traits, relative weight of internal organs and some blood parameters in broiler chickens. Two hundred and forty one-day-old broilers (Ross 308) were used in a completely randomized design with four treatments with six re...
متن کاملEffect of Different Levels of Germinated Barley on Live Performance and Carcass Traits in Broiler Chickens
An experiment was conducted to evaluate the effect of different levels of germinated barley (GB) on live performance and carcass traits in broiler chickens. The experiment lasted for 5 weeks starting from 7 days of age and ending at 42 days of age. Chicks (Ross 308) were fed six dietary treatments including a corn–soy diet (corn diet), a barley–soy diet (barley diet), a barley diet plus enzymes...
متن کاملEffect of Various Levels of Protein in Diet Based on Total and Digestible Amino Acids on Performance of Cobb Strain Broilers
In order to study the effects of various levels of protein in diet based on total and digestible amino acids on performance and carcass traits of broilers, an experiment was conducted as a completely randomized design with 288 broiler chicks from Cobb 500 strain in 6 treatments, each treatment consist of 3 replicates with 16 chicks per replicate. Treatments were the diets as follow: 1) diet for...
