Carcass/body

Growth Performance Response. The consistent net effect of anaboHc steroid implant use in growing mminants appears to be increased rate of protein and Hve weight gain, and increased Hve weight at which carcass or empty body fat concentration equals that in nonimplanted cattie thus increasing their potential mature size. Increased feed intake is frequentiy observed. 

Selenium. Selenium, thought to be widely distributed throughout body tissues, is present mostly as selenocysteine in selenoproteins or as selenomethionine (113,114). Animal experiments suggest that greater concentrations are in the kidney, Hver, and pancreas and lesser amounts are in the lungs, heart, spleen, skin, brain, and carcass (115). 

The carcass or body ply of the tire is made up of fabric yams, typically of steel, nylon, rayon, or polyester, twisted into parallel weft-less cord layers known as plies. These plies are loaded with NR-based compound loaded with adhesion promoters to generate a bond between the cord surface and other tire components. 

Table IV records a study of tissues in which the nitrosating agent occurred. Two mice were exposed to NO j killed with C02> and dissected to give the skin, liver, lungs, and remainder of the body ("carcass") Corresponding tissues of the 2 mice were combined and frozen in liquid N The entire tissue, or 5 g of the carcasses (total weight, 41 g) was homogenized, 10 mg...

Postmortem findings include dark-tarry blood discharge from body orifices, absence of rigor mortis, hemorrhage of the mucous membranes, bloating, and rapid decomposition of the carcass. 

Postmortem findings include small hemorrhages present in the internal organs, carcasses may be jaundiced, fluid in body cavities that frequently is blood-stained, intestinal inflammation, edematous and hemorrhagic gall bladder, and the liver may be necrotic. 

Yellow-crowned night-heron, Nycticorax violaceus, Louisiana 1978-79, whole body, total chlordanes Osprey, Pandion haliaetus Eastern U.S., 1975-82, dead or moribund, carcass (less skin, feet, and beak) ND 10... 

Fed diet containing 424 ng2,3,7,8-TCDD/kg ration for 13 weeks, then fed clean diet for another 13 weeks No overt signs of toxicity. After 13 weeks, 78% of the total 2,3,7,8-TCDD was in carcass and visceral fat, and the rest in liver (9%), gill (5%), skin (3%), muscle (2%), and Gl tract, pyloric caeca, kidney, spleen, and heart. At least 96% of the 2,3,7,8-TCDD was not metabolized however, gall bladder bile had 4 TCDD metabolites. The half-time persistence for 2,3,7,8-TCDD in whole body was 18 weeks, and for individual organs 6-19 weeks 18... 

Adult females and weaned juveniles of both sexes held in outdoor flight enclosures roost boxes treated with 69,300 mg PCP/kg and wood shavings contained 65,000 mg/kg FW All dead within 24 h (90% survival in controls after 32 days). Carcasses of dead bats had 13.1 mg PCP/kg FW. Total PCP burden, in pg, ranged from 17-152 in whole body and 29-181 in fur. Maximum tissue concentrations, in pg/kg FW, were 99 in fat, 65 in liver, 25 in kidney, and 30 in remainder (Shore et al. 1991)... 

The effect of concentration on the fate of [14C] -hexane after inhalation exposure has been studied in Fischer 344 rats (Bus et al. 1982). The disposition of radioactivity was dose-dependent, with 12, 24, 38, and 62% of the acquired body burden excreted as -hexane by the lung with increasing exposure concentration (500, 1,000, 3,000, and 10,000 ppm, respectively). In contrast, 38, 31, 27, and 18% of the body burden of radioactivity was recovered as expired C02 and 35, 40, 31, and 18% was recovered in the urine with increasing -hexane concentration (expired air and urine were collected for 72 hours after exposure). Radioactivity remaining in the tissues and carcass 72 hours after exposure represented 6.1, 8.8, 7.4, and 5.4% of the body burden for the respective exposures. The dose-dependent elimination of radioactivity was apparently due in part to an inhibition of -hexane metabolism reflected by a decrease in total 14C02 and urinary 14C excretion after 10,000 ppm exposure compared to the 3,000 ppm exposure. Half-lives for excretion were estimated from the data. Urinary half-time for excretion of radioactivity was 12.7 hours at 500 ppm. 

Metabolic Balance Methods. Theoretically, the amount of mineral retained in the body should be determinable by balance methods. Heroux and Peter (50) attempted to do this for calcium and magnesium in rats fed three diets. For rats fed their stock diet, they predicted from balance data that the carcasses would contain 23.8 g calcium and 605 mg magnesium. By analysis, the carcasses contained 4.45 g calcium and 152 mg magnesium. However, the relationship between calcium balance data (X) and carcass data (Y) were closely related (Y = 1.05X -. 03, r = 0.99 for group mean data) in the rat data of Whittemore et al. (51). 

Oleic acid is a normal constituent of animal fat, including ant fat. When an ant dies and its body begins to decompose, its fat breaks down and releases odoriferous fatty acids. If the ant dies within its nest, the odor of oleic acid serves as a posthumous chemical signal to its surviving nestmates. On detecting oleic acid, an ant worker s response is to pick up the source (the dead ant) and carry it a short distance toward the nest entrance before setting it down. Eventually, after several workers have moved it, the carcass reaches the entrance, where it is finally ejected from the nest. 

Under special conditions, such as hot weather followed by a freeze and drought, cyanogenic compounds can accumulate in cherry leaves. Caterpillars such as the Eastern tent czterpi hr,Malacosoma americanum, concentrate the toxic substances further in their bodies. Finally livestock inadvertently ingest their feces and carcasses on pastures or from water tanks. In 2001, this resulted in over...
