Conjugated linoleic acids (CLA) have been demonstrated to be a potent inhibitor of milk fat synthesis in ruminants, but effects on carcass composition and organ weight are unknown. Our objectives in this experiment were to determine the dose response of ruminally protected CLA on the performance, organ weight, and fatty acid (FA) composition of early lactation dairy ewes. Twenty-four multiparou...

The study involved 110 hybrid grower-finisher pigs from Polish Large White × Polish Landrace sows sired by Pietrain breed boars and their crossbreds with the 990 line and Duroc. The aim of the study was to determine an association of the polymorphism of RYR1, myogenin (MYOG) genes and carcass meatiness level with carcass slaughter value and meat quality traits in hybrid pigs. Better meat qualit...

• Body fluid and electrolyte composition in congestive heart failure has been studied by the metabolic balance technique," by analysis of skeletal muscle and other tissues' ~ and by the administration of tracer substances," but not by whole body analysis. As part of another study evaluating the effects of digitalis-like compounds on myocardial composition, we thought it appropriate to analyze c...

The increased inclusion of unsaturated fats in pig diets has raised issues related to pork carcass fat quality. The objective of this experiment was to more precisely measure how differing levels of daily fatty acid intake alters the fatty acid composition in 3 different fat depots. A total of 42 gilts and 21 barrows (PIC 337×C22/29) with an average initial weight of 77.80±0.38 kg were allotted...

Objectives were to investigate the effects of prolonged gestational and/or postnatal heat stress on performance and carcass composition of market weight pigs. Pregnant gilts were exposed to gestational heat stress (GHS, 28°C to 34°C, diurnal) or thermal neutral (18°C to 22°C, diurnal) conditions during the entire gestation or during the first or second half of gestation. At 14 wk of age (58 ± 5...

The contributions of replacing rye-grass (Lolium spp.) hay with banana (Musa acuminata) by-products on carcass and tissue characteristics, pH color, in the Canary hair sheep breed were studied. Twenty-two lambs an initial live weight 14.8 ± 2.5 kg individually housed fed two different diets for 58 days: first group (experimental diet) received as forage a mixture fresh composed by leaves pseudo...
