Received: 29/04/2013 Revised: 17/09/2013 Accepted: 23/09/2013 Abstract Accurate prediction of carcass evaluation in live animals may allow more efficient genetic improvement of meat quality. Effective value-based marketing programs require precise techniques for assessing composition, palatability and other factors associated with consumer acceptance of meat products. The ultimate test for a ca...

Live animal and carcass data were collected from market barrows and gilts (n = 120) slaughtered at a regional commercial slaughter facility to develop and test prediction equations to estimate carcass composition from live animal and carcass ultrasonic measurements. Data from 60 animals were used to develop these equations. Best results were obtained in predicting weight and percentage of bonel...

The objective of this study was to compare methods for estimative of body composition of goats based on tritiated water space technique (TOH), specific gravity (SG) of carcass and 9-11 ribs. Ten Toggenburg x Alpine intact male goat kids, from 5.3±0.4 to 25.9±1.3 kg of body weight (BW), were used to estimate body composition by: 1) direct method, 2) TOH method, 3) SG of the carcass and 4) SG of ...

Real-time ultrasonography (RTU) was used to measure the longissimus dorsi muscle (LM) volume in vivo and to predict the carcass composition of rabbits. For this, 63 New Zealand White × Californian rabbits with 2093±63 g live weight were used. Animals were scanned between the 6th and 7th lumbar vertebrae using an RTU equipment with a 7.5 MHz probe. Measurements of LM volume were obtianed both in...

Twenty-one Simmental crossbred bulls (311 -+ 11 kg, 9 mo of age) were used to determine the effect of feeding 10, 12 or 14% CP on concentrations of hormones in blood and the relationship of these hormones to composition of gain. Six bulls were slaughtered on d 0 to provide an estimate of initial carcass composition (9-11 rib section). Remaining bulls were assigned to dietary treatments. Blood s...

this experiment was conducted to study the effect of dietary n-3 to n-6 ratio on performance, immune response, blood parameters and fatty acids profile of broiler chickens. a total number of 192 one day old broiler chicks were randomly alloctted into 6 groups. chicks of groups 1, 2, 3, 4, 5 and 6 were fed balanced corn-soybean diets containing n-3 to n-6 ratios of 1:1, 1:3, 1:5, 1:7, 1:9 and 1:...

Because economic value of carcasses is dependent primarily on carcass weight and carcass quality, feedlot managers have an interest in factors associated with maximizing these two variables. The NRC (1996) proposes that body composition (fat and protein) and carcass characteristics of beef cattle at a specified percentage of mature body weight (BW) are fixed, which indicates that maturity, rath...

OBJECTIVE This experiment was conducted to investigate the effects of fungal treated oil palm fronds (FTOPF) on performance, carcass traits, meat quality, and muscle chemical composition. METHODS Eighteen growing crossbred male goats (Thai Native×Anglo Nubian) with 18.7±2.0 kg of initial body weight (BW) were stratified and blocked by BW in a randomized complete block design. Three diets cont...
