Effect Of Feeding

Smallholder farmers in sub-Saharan Africa offer their stocks little or no supplementary feed but depend mostly on native pastures which are in low nutrient quality. The study was aimed at evaluating the effect of feeding regime on growth performance, nutrient metabolism, rumen indices and economics of production of Yankasa rams fed basal diets of grain sorghum hay or silage supplemented with concentrate. Sixteen growing Yankasa rams weighed 17.0±0.2 kg were randomly assigned to four feeding regime treatment: T1 = Sorghum hay + concentrate daily, T2  = Sorghum silage + concentrate daily, T3  = Sorghum silage  + concentrate  after  1-day  and  T4    =  Sorghum  silage  +  concentrate  after  2-days.          The parameters measured were hay intake, concentrate intake, total feed intake, daily feed intake, initial weight, final weight, weight gain, daily weight gain, feed conversion ratio (FCR), apparent nutrient digestibility, nitrogen balance and costs-benefit. The result showed that hay intake (25.28 – 29.23 kg), concentrate intake (6.19 – 19.41 kg), total feed intake (35.41 – 48.47 kg), daily weight gain (0.04 – 0.05 kg) and weight gain (2.85 – 3.35 kg) were significantly (P<0.05) affected by the feeding regime with rams fed silage + concentrate daily recording higher values. Better FCR was obtained in rams fed silage + concentrate after 2-days. Dry matter (79.22%), crude protein (85.59%), NDF (75.30%) and ADF (78.02%) digestibility coefficients were higher (P<0.05) for rams fed silage + concentrate after 1-day (every other day). The percentage of nitrogen absorbed and retained were higher (P<0.05) in rams fed silage + concentrate after 1-day (85.62 and 82.72%, respectively). The cost per kg gain of N1046.40 for rams fed hay + concentrate daily was significantly (P <0.05) lower than the cost per kg gain of other feeding regimes. It can be concluded that sorghum silage could be fed alongside concentrate daily for improved feed intake and weight gain, but for better cost-efficiency, it is recommended that farmers should feed hay and supplement concentrate daily to rams.     Les petits exploitants agricoles d'Afrique subsaharienne offrent peu ou pas d'aliments supplémentaires à leurs stocks, mais dépendent principalement de pâturages indigènes de faible qualité nutritive. L'étude visait à évaluer l'effet du régime alimentaire sur la performance de croissance, le métabolisme des nutriments, les indices rumen et l'économie de la production de béliers Yankasa nourris à des régimes basaux de foin de sorgho de grain ou d'ensilage complétés par du concentré. Seize béliers Yankasa en croissance pesaient 17,0±0,2 kg ont été assignés au hasard à quatre traitements du régime alimentaire : T1 = foin de Sorgho + concentré tous les jours, T2 = ensilage de Sorgho + concentré tous les jours, T3 de Sorgho + concentré après 1 jour et T4 = ensilage de Sorgho + concentré après 2 jours. Les paramètres mesurés étaient l'apport en foin, l'apport en concentré, la consommation totale d'aliments pour animaux, l'apport quotidien en aliments pour animaux, le poids initial, le poids final, le gain de poids quotidien, le rapport de conversion des aliments pour animaux (FCR), la digestibilité apparente des éléments nutritifs, l'équilibre azoté et les coûts-avantages. Le résultat a montré que l'apport en foin (25.28 à 29.23 kg), l'apport en concentré (6.19 à 19.41 kg), la consommation totale d'aliments (35.41 à 48.47 kg), le gain de poids quotidien (0,04 à 0,05 kg) et le gain de poids (2.85 à 3.35 kg) ont été considérablement (P<0.05) affectés par le régime d'alimentation avec des béliers nourris à l'ensilage + concentré enregistrant quotidiennement des valeurs plus élevées. Un meilleur FCR a été obtenu dans l'ensilage alimenté par bélier + concentré après 2 jours. Matière sèche (79.22 %), protéines brutes (85.59 %), NDF (75.30 %) et ADF (78.02%) les coefficients de digestibilité étaient plus élevés (P<0.05) pour les béliers nourris à l'ensilage après 1 jour (tous les deux jours). Le pourcentage d'azote absorbé et retenu était plus élevé (P<0.05) chez les béliers nourris à l'ensilage + concentré après 1 jour (85.62 et 82.72 %, respectivement). Le gain par kg de N1046.40 pour les béliers nourris quotidiennement au foin + concentré était significativement (P <0.05) inférieur au coût par kg de gain des autres régimes alimentaires. On peut conclure que l'ensilage de sorgho pourrait être alimenté aux côtés du concentré quotidien pour améliorer l'apport alimentaire et le gain de poids, mais pour une meilleure rentabilité, il est recommandé que les agriculteurs nourrissent le foin et complètent le concentré quotidiennement aux béliers

Background: The red-crowned crane (Grus japonensis) is one of the most vulnerable bird species in the world. Mycotoxins are toxic secondary metabolites produced by fungi and considered naturally unavoidable contaminants in animal feed. Our recent survey indicated that the mycotoxins had the potential to contaminate redcrowned crane’s regular diets in China. Objective: This experiment was conducted to investigate the protective effects of mycotoxin binder montmorillonite (Mont) on growth performance, serum biochemistry and oxidative stress parameters of the red-crowned crane. Methods: 16 red-crowned cranes were divided into four groups and fed one of the following diets; a selected diet, regular diet, or the selected diet or regular diet with 0.5% montmorillonite added to the diets. The cranes' parameters of performance, hematology, serum biochemistry and serum oxidative stress were measured. Results: Consuming regular diets decreased the average daily feed intake (ADFI), levels of haemoglobin (Hb), platelet count (PLT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT), but increased the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK) and lactate dehydrogenase (LDH). The supplementation of 0.5% Mont provided protection for the red-crowned crane in terms of feed intake, serum biochemistry and oxidative stress. Moreover, Mont supplementation had no adverse effect on the health of red-crowned crane. Conclusions: Taken together, these findings suggested that the addition of dietary Mont is effective in improving the health of red-crowned crane.
