The pork industry is constantly seeking economical methods which will increase production efficiency and carcass quality. Three nutritional management “tools” at pork producer’s disposal that have been demonstrated to improve growth performance and carcass characteristics are: 1) adding rendered animal fats to diets; 2) adding the recently approved feed additive ractopamine to finishing diets; ...
Foraging in stopover areas influences nutritional condition of birds during spring migration. Our purpose was to determine if body mass, percent carcass water, and serum biochemistry would predict energy reserves (carcass fat and protein) in northern pintails (Anas acuta) at a spring staging area, Lake St. Pierre in Québec, Canada (46 degrees 11 'N, 73 degrees 08 'W). Northern pintails were col...
This experiment was conducted to study the effects of using cotton-seed meal on the performance and carcass yield of broiler chickens at different ages. The experiment was performed in a completely randomized design with four treatments and five replicates for each treatment. The experimental treatments included the levels of 0, 3.5, 7, and 10.5% of cotton-seed meal in diets fed to chickens at ...

Live animal and carcass data were collected from market barrows and gilts (n = 119) to determine the accuracy and precision of using a single longitudinal scan, parallel to midline, in estimating body and carcass composition. Data from test pigs (n = 96) were used to develop prediction equations. Best results were obtained in predicting weight of boneless cuts (ham, loin, and shoulder), weight ...
Real-time ultrasound is a useful technology for measuring carcass composition in live animals and to select future seedstock for carcass merit. Therefore, the objective of this study was to evaluate the use of ultrasound to predict the amount of fat and muscle in Iberian pigs. A total of 163 Iberian pigs were ultrasonically scanned one day before slaughter, and carcass composition was also dete...
In the present contribution we compared the entomological succession pattern of a burned carcass with that of an unburned one. For that, we used domestic pig carcasses and focused on Calliphoridae, Muscidae and Sarcophagidae flies, because they are the ones most commonly used in Postmortem Interval estimates. Adult and immature flies were collected daily. A total of 27 species and 2,498 specime...
A study was conducted in 2 phases to evaluate the effectiveness of 1) the VIAscan Beef Carcass System (BCSys; hot carcass system) and the CVS BeefCam (chilled carcass system), used independently or in combination, to predict Uruguayan beef carcass fabrication yields; and 2) the CVS BeefCam to segregate Uruguayan beef carcasses into groups that differ in the Warner-Bratzler shear force (WBSF) va...
Twenty-four cull beef cows from the University of Florida beef ranches were selected in order to examine the effects of short-term feeding and postmortem aging on cull cow carcass characteristics and palatability attributes from selected muscles. Cull cows were randomly assigned to a treatment of 0, 42, or 84 d (n=8 each) on a limit fed concentrate ration of 25 lb/d prior to harvesting. Upon co...
The effects of contrasting photoperiods (16L:8D vs 8L:16D) and ambient temperatures (5 C vs 18 C vs 31 C) on performance traits of ewe lambs have been evaluated. Seventy-two lambs were paired and allotted to one of six treatment groups in a 2 x 3 factorial experiment. The lambs were fed a pelleted diet ad libitum. throughout the 14-wk study (i.e., as lambs progressed from 12 to 26 wk of age). A...
