Comparative performance of five genotypes of Indonesian large ruminants. 3. Growth and development of carcass tissues

Abstract

The chemical constituents of carcasses from 105 serially slaughtered bulls comprising Madura, Ongole, Bali, Grati (Friesian cross) and swamp buffalo were determined from ground rib joints from all animals and ground carcass sides from 48 bulls. Other carcass quality attributes were also assessed on each carcass. The bulls had previously been fed diets containing 85 or 30% concentrate for up to 280 days. Huxley's allometric equation was used in its logarithmic form as the basis for covariance analyses of the data. Rates of fattening on the 85% concentrate.diet, in decreasing order, were buffalo and Bali, Madura and Ongole, then Grati. There was a genotype by diet interaction for carcass protein, ether extract and energy in that the Madura bulls produced fatter carcasses on the high-concentrate but the leanest carcasses on the high-roughage diets. Buffalo carcasses were low scoring with small rib eye areas and high levels of subcutaneous fat, whereas the highest-scoring carcasses were those from Madura and Bali bulls. Genotype differences in daily carcass protein retention are discussed in relation to rate of maturing and also dietary influences.

Growth and distribution of non-carcass components of Small East African and F1 Norwegian crossbred goats under concentrate diets

“…The displayed tendency for the crossbred goats to have numerically higher percentage of TNCF in EBW, despite being relatively younger than SEA goats, is contrary to the findings by Mahgoub and Lu (1998) and Moran and Wood (1986). The authors noted higher proportions of body fat and non-carcass fat in EBW for smaller early maturing breed than for larger late-maturing breed.…”

Effects of concentrate supplementation on carcass and meat quality attributes of feedlot finished Small East African goats

“…This recording was later used to calculate abattoir, commercial and true dressing percentages and chilling losses. Chilling loss was calculated as the weight lost after chilling the right half-carcasses at 0°C for 24 h. Various linear measurements were taken on the cold halfcarcasses to determine carcass conformation: internal carcass length (CL, from the lumbo-sacral joint to the cervicothoracic joint), carcass depth (CD, from the dorsal to the ventral edges of the carcass side along the 9th rib) and hind leg length (LL, from the ridge of the distal end of the tibia to the cut edge of the subcutaneous fat along a line joining the anterior pubic symphysis) (Moran and Wood, 1986). Internal carcass length was used to determine carcass compactness (CCW/CL).…”

Slaughter performance and meat quality of intact and castrated Washera sheep kept under feedlot condition

“…According to Moran and Wood (1986), meat composition is an important aspect of meat quality and is normally assessed by the amount of physical dissected tissues or chemical analyzed constituents. The lower intramuscular fat concentration of meat produced from intact sheep is associated with an increased moisture concentration.…”
