“…The differences in ADG between supplement levels is an attribute of higher CP and ME intake that allows more mi-crobial population growth and therefore promote digestion making nutrient available to increase weight gain in sheep supplemented with high level of concentrate. These findings are in agreement with that reported by Tsegay et al [38] who observed higher ADG for the sheep supplemented with 350 g/d concentrate than those supplemented with 150 g/d. Dereje et al [37] surements between supplement groups may be largely attributed to the higher CP and ME intake that enhanced skeletal growth.…”

An experiment arranged in 2 × 3 (2 concentrate supplement levels (CSL) and 3 breeds) factorial was carried out to evaluate the effect of CSL, breeds, and their interaction on feed intake, digestibility, feed utilization efficiency, and blood profiles of Ethiopian fat-tail hair sheep. The CSL were 1% and 1.75% body weight, designated as L1 and L2, respectively. The breeds used were yearling intact male Blackhead Ogaden (BHO), Horro and Washera. Sixteen sheep from each breed were divided into two based on initial body weight and randomly allocated to two dietary treatments for digestibility and growth trials of 10 and 90 days, respectively. Grass hay as a basal diet was offered ad libitum to each sheep. Feed intake every day and live body weight at interval of ten days were recorded for the duration of the experiment. Blood samples and linear body measurements were taken a week before the end and on the last day of the experiment from all sheep, respectively. Dry matter and nutrient intakes, except concentrate supplement and CP, were influenced by the interaction. The higher (p < 0.0001) DM digestibility was recorded from sheep supplemented with L2 than L1. Consequently, sheep supplemented with L2 had significantly higher (P < 0.05) feed conversion efficiency (FCE), average daily gain (ADG) (57.3 vs 44.2 kg), total gain (TG) (5.3 vs 3.9 kg) and final body weight (FBW) than those supplemented with L1. Among breeds, Horro sheep recorded higher (P < 0.05) DM intake, digestibility, and FCE than the rest of the breeds. Consequently, this breed has significantly (p < 0.05) higher TG, ADG, and FBW. Some of the blood hematology (PCV, MCV, neutrophils, and monocytes) and sera metabolites (total protein, urea, and cholesterol) How to cite this paper: Ayele, S., Urge, M. 150values were influenced by the interaction in favor of L2. Hemoglobin concentration was higher for Washera than the other breeds (p < 0.05) but similar for the two CSL (P > 0.05). In conclusion, the study indicate the presence of variation in nutrient intake and utilization, performance traits, and blood profiles among breeds and between CSL, most of which were in favor of Horro breed and high level of concentrate.

“…It may also be speculated whether larger and heavier head, offals and skin of the Dorper lambs contribute to the lower dressing percentage of this breed. Unfortunately, there are no previous studies appropriate to compare with from the region except the Ethiopian study on crosses between Dorper and Blackhead Ogaden, where the Dorper crosses clearly had the highest dressing percentage (Tsegay et al 2013). …”

“…Results from carcass studies on indigenous sheep breeds in Ethiopia show some breed differences for both carcass weight and fat deposition (Ermias et al 2002; Ermias et al 2006). Crossbred Blackhead Ogaden with Dorper has been reported to have improved carcass weights by 15 % compared to pure Blackhead Ogaden (Tsegay et al 2013). There are, however, no comparative studies on carcass traits of Red Maasai and Dorper sheep and their crosses.…”

Meat production is the most important trait in the breeding objectives of sheep production in East Africa. The aim of this study was to investigate breed differences in live weight, conformation, carcass traits and economic values for meat production among Red Maasai and Dorper sheep and their crosses. In total, 88 ram lambs, which were reared at the ILRI experimental station, Kapiti plains Estate in Central Kenya, were used for the study. The lambs were slaughtered at Kenya Meat Commission (KMC) at about 1 year of age. Prior to slaughter, the lambs were weighed, measured and assessed by experienced evaluators, and at the abattoir carcass traits were recorded. Large breed differences were found for most traits. Dorper lambs were heavier at delivery for slaughter and had better carcass grade but lower dressing percentage and fat levels than Red Maasai. Crossbreds were generally better than the parental breeds. Evaluators were willing to pay more for the Dorper lambs for slaughter although carcass weights later were shown not to be higher than for Red Maasai. Evaluators undervalued Red Maasai lambs by 8–13 % compared to Dorper lambs according to the prices quoted per kilogramme live or carcass weight by KMC. Live weight was better than any other live measure in predicting carcass weight. Due to the overall higher ranking of the crossbred lambs for meat production, Dorper may be useful as a terminal sire breed for crossing with Red Maasai ewes.

RESUMO Objetivou-se avaliar os efeitos do zinco ou do propilenoglicol sobre o desempenho e nas características da carcaça e da carne de ovinos sob pastejo em pastagem nativa da Caatinga. Utilizaram-se 24 ovinos, mestiços Santa Inês, machos, não castrados, peso inicial de 19,3±2,52kg, com quatro meses de idade, oito repetições por tratamento, distribuídos em um delineamento inteiramente ao acaso. Os tratamentos foram: sem aditivo, controle (CT), adição de sulfato de zinco (ZnSO4.7H2O) (Zn) para fornecimento de 300mg de Zn dia-1 via sal mineral, e propilenoglicol (PG), 2,5mL kgPC0,75-1 animal-1 dia-1 misturado no concentrado. Os animais foram suplementados com concentrado constituído de milho (54,0%), farelo de soja (45,1%) e calcário (0,911%) em 0,7% do PC médio de cada tratamento. O ensaio foi conduzido durante quatro meses (março a junho/2014). Avaliaram-se o desempenho e, após o abate dos animais, as características de carcaça e os componentes não carcaça, os parâmetros físico-químicos e organolépticos na carne. O Zn e o propilenoglicol não afetaram o desempenho e os parâmetros da carcaça em termos absoluto e relativo, bem como os pesos dos cortes e seus rendimentos (P>0,05). Não houve efeito dos aditivos nas características organolépticas e nos aspectos físico-químicos da carne (P>0,05), exceto cinzas (P<0,05). O zinco e o propilenoglicol não melhoram o desempenho e as características da carcaça de animais terminados em pastagem nativa da Caatinga. O baixo suprimento energético devido à má qualidade do pasto entre os meses de abril a junho contribui para a ineficiência no aproveitamento dos constituintes proteicos, implicando menor consumo e consequente diminuição do desempenho.
