Eighteen Saidi rams were used in this trial to study the impact of additive mannan oligosaccharide (MOS;activeMOS ®)on some of carcass characteristics. MOS are commercially available as BioMos®, which is a nutritional supplement manufactured by MOS ® Matrix nutrition, LLC, USA was used in this experiment. Animals were randomly divided into three equal groups. The initial average live body weight values were 24.00,24.08 and 24.17 kg for groups 1,2, and 3 respectively. The first group did not receive MOS and served as a control group, while the second and third groups were supplemented with 2 and 4 g/ kg diet MOS and served as a MOS 1 and MOS 2 groups, respectively. Both experimental groups were fed roughage and concentrate diets ad libitum during this study. At the end of the experimental period, lasted for 6 months, final average body weight values were 44.17, 48.50 and 45.83, respectively. Five animals from experimental groups were slaughtered. The data revealed that supplementation of dietary MOS in the diet of siadi rams increased hot carcass weight, dressing percentage, right (P<0.05) and left side percentages. Moreover, most of edible and non edible parts tended to be heavier for MOS treated rams, while fat of heart, kidney and pelvic, gut, intestine and total fat tended to be lower for these groups than a control group. The proportion of muscle/ bone and muscle/fat ratios increased in treated groups. Left carcass side weight and carcass cuts were heavier in animals fed diet supplemented with MOS than controls. Meanwhile, a high priced cuts (leg, sirloin and best neck and fillet) were heavier by 29.05% and 12.7% of rams fed diet supplemented with MOS 1 and MOS 2 additives, respectively compared with the control. The highest part of high priced cuts was observed in fillet cut for MOS 1 and MOS 2 supplementation by about 57.14% (P<0.05) and 14.29%, respectively than control rams. Individual skeletal muscle of Semimemberanosus (SM), Supraspinatus (SP) and Longissimus dorsi (LD) were increased in the case of the dietary supplementation with MOS. Consequently, it appears from the present study that the dietary of MOS improve carcass characteristics and meat quality. Moreover, MOS inclusion at 0.2% was the most effective, suggesting that MOS might be a potential type of food additive useful for the growing sheep in Upper Egypt conditions.

“…Cassard et al (1969) reported that Suffolk lambs had greater longissimus muscle area than wool type breeds of sheep, which could indicate a higher lean and a lower fat percentage in Suffolk than in Targhee sheep. Chemical analysis of soft tissue (Dahmen et al, 1985) from racks showed that Suffolk-sired lambs had a higher percentage of protein and a lower percentage of fat than did Lincoln-sired lambs. When comparisons are made at the same weight, genotypes that are heavier at maturity generally grow faster and contain less fat and more protein and bone in their whole bodies than do animals of smaller mature size (Theriez et al, 1981).…”

Suffolk and Targhee ewes (30 each) with single or twin lambs were used in four periods beginning in late gestation and continuing through weaning to evaluate breed differences in milk production, lamb BW, and DMI by ewes and lambs. In Periods 1 (late gestation) and 2 (early lactation), ewes (Period 1) and ewes with lambs (Period 2) were individually penned, fed .45 kg of barley x ewe(-1) x d(-1) and allowed ad libitum access to chopped alfalfa. Ewes and lambs grazed native range in Periods 3 and 4. Grazed forage DMI was estimated using chromic oxide. Estimates of milk production were obtained by handmilking. Average lamb age was 4, 45, and 73 d at the beginning of Periods 2, 3, and 4, respectively. Milk production tended (P = .20) to be greater for Suffolk than for Targhee ewes. Targhee ewes produced 85% more (P = .001) wool than Suffolk ewes. From 33 d prepartum to 89 d postpartum, Suffolk ewes consistently weighed more (P = .001) than Targhee ewes. Suffolk ewe BW loss (-.15 kg/d) was greater (P = .01) than Targhee ewe BW loss (-.02 kg/d) from 33 d prepartum to 6 d postpartum. From 6 to 89 d postpartum BW gain did not differ (P = .69; .05 kg/d) between breeds. From birth to 89 d postpartum, Suffolk lambs consistently weighed more than Targhee lambs (P = .003). From birth to 89 d postpartum, ADG was greater for Suffolk than for Targhee lambs (P = .006). Targhee ewes consumed 25% more (P = .01) feed over the course of the study than did Suffolk ewes. Grazed forage DMI by Targhee lambs was 26% greater (P = .01) than DMI by Suffolk lambs. When meat production is the primary income from sheep, one potential advantage of Suffolks compared with Targhees is more rapid gain with less feed intake.

“…Comparando o efeito do sistema de terminação (pastagem e confinamento) sobre a área de olho de lombo, McCLURE et al (1994) detectaram diferenças, contrariando resultados encontrados por ARNOLD e MEYER (1988). O efeito de genótipo para esta variável foi observado por vários pesquisadores, destacando: WOLLF et al (1980), DAHMEN et al (1985, ARNOLD e MEYER (1988) e FAHMY et al (1992, em contraposição aos resultados encontrados por CROUSE et al (1981), LLOYD et al (1981), SNOWDER et al (1994) e WYLIE et al (1997.…”

O objetivo deste experimento foi comparar as características qualitativas de carcaças de 36 cordeiros terminados em pastagem de coastcross, sendo 13 Corriedale, 14 Bergamácia x Corriedale e 9 Hampshire Down x Corriedale, e 29 cordeiros terminados em confinamento, sendo 10 Corriedale, 11 Bergamácia x Corriedale e 8 Hampshire Down x Corriedale. As médias das variáveis (escala de 1 a 5) condição corporal: 2,70 e 3,13; conformação: 2,65 e 3,35; e cobertura de gordura: 2,43 e 2,95; foram superiores para os cordeiros do confinamento que para cordeiros em pastagem. Na escala de 1 a 3, foram avaliadas a cor da gordura: 1,66 e 1,94; cor da carne: 1,66 e 1,72; e consistência de gordura: 1,62 e 1,83, respectivamente, para os cordeiros em pastagem e em confinamento. A área de olho de lombo foi significativamente (10,21 vs. 9,03 cm²), bem como a espessura de gordura de cobertura: 1,10 vs. 1,70 mm, foi superior para os cordeiros confinados. As médias das porcentagens de músculo no lombo foram de 54,92 e 57,94%; para gordura, 9,29 e 12,95%; e osso, 35,78 e 29,10%, respectivamente, para cordeiros em pastagem e confinamento. Entre os sistemas de terminação, não houve diferenças para porcentagem de proteína (19,71 e 19,10%, respectivamente), mas houve diferença para teor de lipídios, com 5,43% para cordeiros em pastejo e 11,54% para cordeiros confinados. Para as variáveis analisadas não houve diferenças significativas entre os cruzamentos.
