“…However, it was expected that the NA would be more similar to the late maturing SAMM. When considering the results it is important to bear in mind that no selection for economically important traits have been done on the NA and that the breed has not been genetically bred for meat production as both D and SAMM were (Epstein, 1960;De Waal & Combrinck, 2000;Sheridan et al, 2003;Buduram, 2004).…”

“…Most of the differences in physical composition between the D and NA can be qualified by the fact that the D is early maturing and the NA late maturing (Epstein, 1960;Webb & Casey, 1995). Carcass composition can be described as the ratio to which the main tissues (muscle, fat, and bone) are found in a sheep carcass (Berg & Butterfield, 1968).…”

“…The NA is well known for its ability to survive the harsh South African climate (Epstein, 1960). The ancestors of the NA can be traced back to the fat-tailed sheep owned by the northern Namaqua Khoi people and thus it is regarded as a national heritage.…”

“…The NA has a slender body with long legs, well adapted for walking vast distances in search of food and water. Body fat is mostly accumulated in the fat-tail and fat deposits on the loin are minor (Epstein, 1960). Fat-tailed sheep are well known for their ability to survive in harsh environments.…”

“…Instead of the subcutaneous layer of fat used for insulation, the adaptive response is to store surplus fat in the tail, with minor fat deposits in the rest of the body. The fat-tail acts as a depot for reserve fat in times of abundance and is utilised when food and water are scarce (Epstein, 1960).…”

This study evaluated the differences in the muscle-fat-bone yield of Namaqua Afrikaner (NA), Dorper (D) and SA Mutton Merino (SAMM) ram lambs. The breeds constituted an indigenous, hardy and late maturing, fat-tailed breed (NA), an early maturing, commercial meat breed (D) and a late maturing commercial dual-purpose breed (SAMM). Lambs were slaughtered at 35 (± 8) days post weaning. Carcasses were cooled for 24 h, separated into retail cuts (leg, loin, rib, and shoulder), weighed and deboned. Meat and fat were separated after deboning and weighed to calculate the muscle-fat-bone yield per cut. Least-square means were computed for the respective breeds, using slaughter age as covariate. Results for percentage meat indicate that, with exception of the rib, retail cuts from the NA breed contained a lower percentage of meat than D and SAMM breeds, particularly in the valuable loin and leg cuts. The shoulder of the NA had a lower percentage meat than that of the D. The percentage fat in retail cuts did not differ between breeds for any of the cuts. In comparison with both D and SAMM, NA contained a higher percentage bone in all cuts. Dorper and SAMM carcasses did not differ in terms of the percentage of bone, fat or muscle for any of the retail cuts. The lower meat yield, particularly in the more expensive loin and leg of the NA, when compared to the commercial meat breed (D) could make the former less preferred for meat production. However, the NA compared more favourably than the dual-purpose SAMM. Differences in carcass composition could be attributed to the fact that the NA is an unimproved and late maturing sheep breed.

A study was conducted to compare carcass and noncarcass yield, carcass composition, conformation, and fat depot partitioning of three Ethiopian fat-tailed hair sheep breeds (Blackhead Ogaden (BHO), Horro, and Washera) under two concentrate supplement levels (CSL). Sixteen sheep from each genotype (8 sheep per concentrate level), a total of 48, were used in a 3 × 2 factorial arrangement (3 breeds and 2 CSL). The two CSL were 1% (L1) and 1.75% (L2) body weight. Animals were about a year of age at the start of the experiment and all were slaughtered after 90 days of fattening. Dressing percentage per SBW was in the orders of Horro > BHO = Washera (P < 0.001). Total edible noncarcass component yield per EBW (TENCCY/EBW) of Horro breed (21%) was heavier (P < 0.0001) by about 2.8% than that from BHO and Washera sheep. Blackhead Ogaden sheep had significantly (P < 0.05) higher fat percentage and fat to bone ratio, while lower lean to fat ratio than Horro and Washera sheep. The fat partitioning results showed that carcass depot is the major fat depot in BHO and Horro sheep, whereas carcass fat and tail fat in Washera sheep had comparable value. The highest (P < 0.0001) carcass compactness index (CCI) value was obtained in Horro sheep, while the value for Washera was the lowest coupled with leg compactness index; as a result, Washera sheep had poor carcass conformation. Sheep supplemented with L2 had heavier HCW and CCW (P < 0.0001), wider RMA, and dressed better (P < 0.001) than L1-fed sheep. Carcass fat per CCW, carcass fat per total body fat (TBF), TYEP per SBW, and CCI values of the L2 diet-fed group were 2.7, 1.8, 1.2%, and 13.2 g/cm, respectively, higher (P < 0.05) than L1-supplemented sheep. The result highlights that Horro and Washera have closely comparable carcass composition, indicating the two breeds were at a similar stage of physiological maturity, while BHO appeared to be an early maturing sheep, suggesting a need for different feeding management for BHO to harvest lean meat. In conclusion, there existed a significant breed variation in most parameters considered in this study, which can be an opportunity to select breeds for various use and production objectives.
