“…Information on yield of non-carcass components of animals is important especially in developing countries as the components are consumed and/or sold and thereby contributing immensely to the consumed dietary protein and increased household income (Moron-Fuenmayor and Clavero, 1999;Sebsibe et al, 2007;Mushi et al 2009b). The weights of individual organs and sub-products, as a proportion of shrunk weight in the present study, however, were not affected by dietary treatments.…”

“…There is limited information on the use of crop residues and performance of the indigenous goats in East Africa in terms of growth rate, carcass characteristics and particularly in meat quality attributes. Information on non-carcass yield is also limiting although the contribution of edible offals to the supply of dietary animal protein and economic gains is substantial (Riley et al;1989;Aduku et al, 1991;Mushi et al, 2009b). The objective of this study was to evaluate the effects of using treated wheat straw alone or in combination with grass hay on growth performance, carcass characteristics, non-carcass yield and meat quality attributes of Small East African (SEA) goats.…”

“…dressing percentage). Indeed, a more developed digestive tract will be larger and heavier, which will decrease the dressing percentage of the animal (Mushi et al, 2009). The GIT of extensively produced lambs is more developed, due to the higher intake of dry matter compared with intensively produced animals of the same age (Priolo et al, 2002;Cañeque et al, 2003).…”

A study was conducted, first, to compare the gastrointestinal tract (GIT), reticulo-rumens and intestinal capacities (relative to body weight) of ram lambs from six Turkish sheep breeds: Turkish Merino (TM, Anatolia Merino), Akkaraman (AK), Kıvırcık (KV), Awassi (AW), Karayaka (KY) and Morkaraman (MK), and second, to examine the influence of sheep breed on the pH of the digesta in the various segments (rumen, jejunum and caecum) of the GIT. Six ram lambs from each breed were slaughtered at 40.2 ± 0.80 kg liveweight. Lambs from the AK breed had a heavier GIT weight than the AW, KY or MK breeds. The weight of the full stomach was higher in AK lambs compared with the other lambs, except for KV lambs, while the relative weight of the empty stomachs was heavier in MK ram lambs than in TM, AW and KY lambs. The AK lambs had the highest relative empty intestinal weight. The relative weight of empty intestines was heavier in KV lambs than in KY lambs. The pH of the rumen content was higher in TM and AK lambs compared with KY and MK lambs, while the pH of the caecum content of KV lambs was higher than those of KY and MK lambs. In conclusion, significant differences were found among the six breeds in terms of some variables that were studied, although a higher proportional GIT weight in the fat-tail breeds such as the MK, AK and AW was not reflected in all components or in the pH of the GIT content. ______________________________________________________________________________________ Keywords: Native sheep breed, digestive system, rumen, small and large intestine, pH value # Corresponding

“…Both concentrates increased empty body weight, carcass weight and dressing percentage of the two goat genotypes. Increased carcass weights resulting from different levels of concentrates offered to goats have been reported by Okello et al (1994) in Mubende goats, Ryan et al (2007) in Boer goats, Mushi et al (2009) andSafari et al (2009) in the Small East African goats and their crossbreds with Norwegian goats. Mahgoub et al (2005) also showed an increased slaughter weight, carcass weight, empty body weight and dressing percentage with increasing level of metabolisable energy in the diets of Omani goats.…”

Growth performance, carcass and non-carcass characteristics of Mubende and Mubende×Boer crossbred goats under different feeding regimes

et al. 2014

a b s t r a c tA surge in the demand for goats' meat both locally and internationally has prompted many goat farmers in Uganda to venture into commercial goat production. However, goat production is highly challenged by breed characteristics and extreme fluctuations in feed quantity and quality. This study evaluated the effects of supplementing grazing Mubende goats and their crossbreds (Mubende Â Boer) with concentrates on growth, carcass and noncarcass characteristics. A 2 Â 3 factorial treatment arrangement was used to randomly allocate 96 pure Mubende and Mubende Â Boer castrates (mean7SE; 31.372.2 kg initial weight) aged between 9 and 15 months, to three feeding regimes. The feeding regimes included (i) sole grazing (SGZ) as control, (ii) controlþ concentrate containing molasses (MCM) and (iii) controlþ concentrate without molasses (MCC). Concentrate dry matter intake was higher (Po0.001) in the crossbreds regardless of concentrate type, however, inclusion of molasses resulted in lower concentrate intake. The Mubende goats were more efficient in utilising concentrate with molasses while the crossbreds utilised concentrate without molasses more efficiently. Average daily gain (ADG) was higher (Po0.001) in the crossbreds and in the supplemented groups. Slaughter weight, empty body weight and hot carcass weight were also higher (Po0.001) in the crossbreds than the pure Mubende. Supplementation reduced gut fill (Po0.001) and increased (Po0.001) hot carcass weight and dressing percentage in both genotypes. Proportion of non-carcass components as percentage of empty body weight did not vary between genotypes but supplementation reduced (Po0.01) proportion of skin with hocks and empty stomach. Kidney fat, omental fat and scrotal fat increased (Po0.001) with supplementation. Therefore, crossbreeding together with supplementation of grazing can considerably improve goat meat production, however, caution should be taken on the level of concentrate supplement offered as tendency for absolute substitution of concentrate for grass/browse by goats was observed in this study.
