“…The CP content of natural pasture hay offered to the experimental animals in the current study was 7.42% comparable with values ranging from 7.02 to 7.9% (Ayele et al., 2017; Mekuriaw et al., 2012; Nega & Melaku, 2009). It has been stated that the ruminant animals require the CP value of 8% and above for better rumen function (Waghorn & Clark, 2004).…”

Background Protein feed resources for ruminant animal productions are deficit in Ethiopia. Objectives To evaluate the supplementation effects of dried Dodonaea angustifolia leaves (DDL), dried traditional brewery by‐product locally called atella and their mixtures on nutrient utilization and growth performance of Farta sheep fed natural pasture hay (NPH) as basal diet. Methods Twenty‐five yearling intact male Farta sheep with average initial body weight of 14.53 ± 1.35 kg (mean ± SD) were used for the study. The experimental sheep were allocated into five blocks of five animals based on their initial body weight. The experiment lasted for 90 days of feeding trial followed by 7 days of digestibility trial. The experimental feeds were NPH ad libitum + 100% DDL + 100 g wheat bran (WB; T1), NPH ad libitum + 75% DDL + 25% dried atella + 100 g WB(T2), NPH ad libitum + 50% DDL + 50% deried atella + 100 g WB (T3), NPH ad libitum + 25% DDL +75% dried atella +100 g WB (T4) and NPH ad libitum + 100% dried atella + 100 g WB (T5). Results NPH, DDL and dried atella contained 7.42, 15.39, 21.13% crude protein (CP) and 66, 36, 34% neutral detergent fiber, respectively. Sheep supplemented with increasing level of atella had more dry matter intake (DMI) and crude protein intake (CPI) and the highest of these DMI and CPI were in T5 (868 g/d for dry matter and 113 g/d for CP). This progressive increased CPI from T1 up to T5 was reflected in a significant (p < 0.001) fibers and estimated metabolizable energy intake in the order of T5 > T4 > T3 > T2 > T1. Significant difference (p < 0.001) was recorded on nutrient utilization and the highest was for T5 and lowest for T1. Average daily gain (ADG) and feed conversion efficiency (FCE) were significantly (p < 0.001) increased as the atella inclusion level increased. Sheep in T4 and T5 had the highest ADG and FCE with the order of T5 = T4 > T3 > T2 > T1. ADG was correlated positively and highly significant with nutrients intake and digestibility. Conclusion Atella supplementation better than DDL and then their mixture (T2–T4) supplementation could be recommended in sheep fattening in the study area.

“…Serum total protein across the treatments ranged from 8.68 to 9.78 g/dL and were significantly different (p<0.05). In this study, serum total protein of 8.68 to 9.78 g/dL was not comparable to values of serum protein (6.4 to 8.3 and 5.81 to 6.36 g/dL) reported for Nigerian and Ethiopian breeds of sheep respectively (Njidda et al, 2014;Ayele et al, 2017). Serum protein above the normal range (6.0-7.9 g/dL) reported by Kaneko et al (2008) among the sheep might be attributed to greater efficiency of dietary protein utilization.…”

Crop residues are potential supplementary feed of small ruminants in Nigeria. However, arbitrary feeding of crop residues without due consideration to proportions and nutritive values could result in poor performance. Information on the proportions of mixed ration of different roughage sources for sheep is limited. Therefore, the effect of mixed ration of crop residues on the rumen fermentation and blood profiles of West African dwarf (WAD) sheep was investigated. Sixteen female WAD sheep with an average live weight of 8.10 ± 0.16kg were used in a completely randomised design with four animals per treatment. Experimental diets (1 to 4) constitutes 53% each of corn cob, cassava peel, groundnut haulm and cowpea husk respectively, with 30% palm kernel sludge, 12% soya bean hull, 4.5% Gliricidiasepium, and 0.5% salt across each diet. The results revealed non-significant (p>0.05) effects of experimental diets on rumen pH and volatile fatty acids. Rumen ammonia nitrogen differed significantly (p<0.05), with the highest (10.17 mg/100mL) and lowest (8.51 mg/100mL) values in sheep fed dietary treatments 4 and 2, respectively. Bacteria counts were highest (1.75 cfu/mLx105) in sheep fed diet 4 and lowest (1.28 x105cfu/mL) in sheep fed diet 3. Rumen fungi and protozoa counts were similar (p>0.05) among treatment groups. Packed cell volume, haemoglobin, and red blood cell counts were highest (52.00 %, 16.95 g/dL and 14.25 x106/µL) for sheep fed diet 4 and lowest (33.00 %, 10.65 g/dL and 11.79 x106/µL) in sheep fed diet 1.While the white blood cell was significantly (p<0.05) highest (8.43 x 103/µl) in sheep fed diet 2, lymphocytes and neutrophils counts were similar (p>0.05) among treatments. Serum biochemical components were significantly different (p<0.05) among the treatments, except aspartate aminotransferase and creatinine. In conclusion, utilization of mixed ration of crop residues as feed did not compromise ruminal activities and the health of WAD sheep. Les résidus de récolte sont des aliments complémentaires potentiels pour les petits ruminants au Nigeria. Cependant, une alimentation arbitraire des résidus de culture sans tenir dûment compte des proportions et des valeurs nutritives pourrait entraîner de mauvaises performances. Les informations sur les proportions de ration mixte de différentes sources de fourrage pour les moutons sont limitées. Par conséquent, l'effet d'une ration mixte de résidus de récolte sur la fermentation du rumen et les profils sanguins de moutons West African Dwarf (WAD) a été étudié. Seize moutons WAD femelles d'un poids vif moyen de 8,10 ± 0,16 kg ont été utilisés dans une conception complètement randomisée avec quatre animaux par traitement. Les régimes expérimentaux (1 à 4) contiennent respectivement 53 % de rafle de maïs, d'écorce de manioc, de fane d'arachide et de cosse de niébé, avec 30 % de boue de palmiste, 12 % de coque de soja, 4,5 % de Gliricidiasepium et 0,5 % de sel dans chaque régime. . Les résultats ont révélé des effets non significatifs (p>0,05) des régimes expérimentaux sur le pH du rumen et les acides gras volatils. L'azote ammoniacal du rumen différait significativement (p<0,05), avec les valeurs les plus élevées (10,17 mg/100 ml) et les plus faibles (8,51 mg/100 ml) chez les moutons nourris avec les traitements diététiques 4 et 2, respectivement. Le nombre de bactéries était le plus élevé (1,75 cfu/mL x 105) dans le régime 4 des moutons et le plus bas (1,28 x 105 cfu/mL) dans le régime 3. Le nombre de champignons et de protozoaires du rumen était similaire (p> 0,05) parmi les groupes de traitement. L'hématocrite, l'hémoglobine et le nombre de globules rouges étaient les plus élevés (52,00 %, 16,95 g/dL et 14,25 x106/µL) pour les moutons nourris avec le régime 4 et les plus bas (33,00 %, 10,65 g/dL et 11,79 x106/µL) chez les moutons régime alimentaire 1.Alors que le nombre de globules blancs était significativement (p<0,05) le plus élevé (8,43 x 103/µl) chez les moutons nourris avec le régime 2, le nombre de lymphocytes et de neutrophiles était similaire (p>0,05) parmi les traitements. Les composants biochimiques du sérum étaient significativement différents (p<0,05) parmi les traitements, à l'exception de l'aspartateaminotransférase et de la créatinine. En conclusion, l'utilisation d'une ration mixte de résidus de culture comme aliment n'a pas compromis les activités ruminales et la santé des moutons WAD.

“…Similar observation has been documented in a comparative study conducted in Ethiopian sheep [11] and goat genotypes [12]. Improvement in carcass yield and dressing percentage of indigenous sheep with increasing level of supplementation as in the case of the current study is well documented [7] [23] and is a function of increased supply of nutrients for muscle development. This is supported by greater rib-eye muscle area of the high concentrate level supplemented group in this study, as rib-eye muscle area is mostly used as a tool to indicate the proportion of carcass muscling [24].…”

A study was conducted to compare the carcass yield and meat quality of Rutana, Gumuz and Washera sheep of Ethiopia under two concentrate supplement levels (CSL), low (300 g/day) and high (450 g/day). The supplement contains 45% wheat bran, 26% maize grain and 29% Noug cake. A total of 36 sheep (12 from each genotype) were used in 3 × 2 factorial treatment arrangement (3 genotypes and 2 CSL) which was used in a completely randomized block design. Hay was fed ad libitum at a rate of 20% refusal. After the completion of 90 days fattening period, all sheep were slaughtered and meat sample from longissimus dorsi muscle of each animal was taken for sensory evaluation and instrumental measurement of tenderness and for color, pH, and chemical composition analysis. Slaughter body weight (SBW) (26.0 vs. 24.1 kg), hot carcass weight (HCW) (11.3 vs. 9.7 kg), dressing percentage (DP) on SBW (43.4% vs. 40.1%) and EBW basis (53.6% vs. 50.9%), and rib eye-muscle (REM) were higher for the high than low CSL. Rutana sheep had heavier HCW (11.9 kg) than Gumuz (10.1 kg) and Washera (9.4 kg) sheep. DP on EBW basis was higher for Rutana (54.7) than Washera sheep (48.1), while the value for Gumuz (50.9) was similar with both genotypes. Meat from high supplemented sheep had higher fat (9.7% vs. 8.8%), tenderness, juiciness, flavor and lower shear forces than the low level of supplementation. Most sensory parameters measured were in the order of Rutana > Gumuz > Washera sheep. It is concluded that Rutana sheep were relatively more suitable than Gumuz and Washera sheep for production of better carcass yield.
