The frequency of Sarcocystis spp. and its effect on winter carcass composition of mottled ducks.
Macrocysts of the protozoan parasite Sarcocystis spp. occurred in 34 of 241 (14%) adult and 6 of 70 (8.6%) immature mottled ducks (Anas fulvigula) that were collected in southwestern Louisiana from 1987 to 1989. The prevalence of Sarcocystis spp. among immature ducks was higher than previously reported, possibly because of a longer exposure period. No differences in carcass composition variable...
متن کاملEffects of L-carnitine administration on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks.
Effects of L-carnitine administration via drinking water on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks was examined. One hundred day-old Turkish native duck chicks were divided into two groups, each with five replicates and given the same diets with 0 and 200 mg/l carnitine chlorhydrate via drinking water. The study lasted 8 weeks, w...
متن کاملPork carcass composition: II. Use of indicator cuts for predicting carcass composition.
Right sides of 30 pork carcasses were fabricated into indicator cuts (Boston butt, picnic, anterior belly, posterior belly, anterior loin, posterior loin, and ham) and used to determine carcass composition by physical dissection and chemical analysis of soft tissue. Linear measures and chemical composition of whole-side grind were collected from left sides. Dissection of indicator cuts to predi...
متن کاملUsing Total Body Electrical Conductivity (TOBEC) and Optical Fat Probes for Estimating Carcass Composition
Current methods of pricing live animals do not adequately recognize differences in carcass composition and therefore do not adequately relate consumer demands to producers. Pricing systems based on carcass merit will be necessary before this relationship can exist. In order for carcass merit pricing systems to be accepted, methods to estimate carcass composition must be both accurate and object...
متن کاملManipulation of porcine carcass composition by ractopamine.
The effect of dietary ractopamine and protein level on growth performance, individual muscle weight and carcass composition of finishing pigs were evaluated in two experiments. Twelve barrows and 12 gilts (Exp. 1) and 32 barrows (Exp. 2) with an average initial weight of 64 kg were penned individually and offered ractopamine at 0 or 20 ppm in diets containing 13 or 17% CP in 2 x 2 factorial exp...
