Effect Of Feeding

A total of 42 growing rabbits of different crossbreds with initial average weight of 1.20kg were fed rations in wghuch rumen content (RC) and blood-rumen content (BRC) proteins were substituted for groundnut cake protein in a completely randomized design. they were grouped into 7 treatments for 3 replicates, each containing 2 rabbits. They were fed RC and BRC in a practical diet at 10, 20 and 30% dietary inclusion levels for 56 days. The average daily feed intake(ADFI), average daily weight gain (ADWG), feed conversion ratio (FCR) and protein efficiency ratio (PER) were not significantly influenced (P>0.05) by the treatments. The dry matter and protein digestibility coefficients were significantly (P<0.05) affected. The feed cost per kg diet and feed per kg gain were significantly(P<0.05)influenced. Among the internal organs evaluated, the liver and the kidney weights, small intestine and caecum length were also significantly (P<0.05) influenced. The dressing percentage was also affected significantly (P<0.05). The study showed that RC and BRc could be influenced at 305 dietary inclusion in growing rabbit's ration without deleterious effect. However, further investigation into long-term effect of feeding on the orgns of the animal is suggested

The study was conducted to evaluate the effect of yeast treated Bovine blood–rumen content mixture (YTBRM) on performance of 60 weaner rabbits with an average weight of 501.96 ± 0.22g. The rabbits were randomly assigned to five dietary treatments with five replicates in a completely randomized design. T1, T2, T3, T4 and T5 had 0%, 10%, 20%, 30% and 40% YTBRM. Data were collected on growth performance, carcass characteristics and haematological indices. At the end of the experiment, 4 rabbits were randomly selected from each treatment and slaughtered to determine the effect of graded levels of YTBRM on carcass yield and internal organs characteristics. The result of growth performance revealed that all parameters measured were significantly (P<0.05) affected by the dietary inclusion of YTBRM except for feed conversion ratio which ranged from 3.05 in T1 to 3.64 in T2. Average daily feed intake was significantly (P<0.05) higher (101.69) in treatment T5 while the other treatment groups were similar.. Average daily weight gain were significantly higher in T (29.72g) and T4 (28.05g) while the least value was obtained in T2 (25.46g). Carcass yield was significant (P<0.05) across the treatment groups. Dressing percentages were significantly (p<0.05) higher in T2 (82.35%), T1 (77.62%) and T4 (74.08%) than T5 (63.57%) and T3 (69.79%). Result of the internal organs shows that they were all similar across the treatment groups. Haematological and biochemical indices shows no significant diffrerence (P>0.05) in all the parameters evaluated. It could be concluded from this study that YTBRM can be included up to 40% in weaner rabbits diet without adverse effect on the growth performance, blood profile, carcass and internal organs characteristics.

ABSTRACT: This experiment was conducted to evaluate the effect of growth promoter additives an alternative to antibiotics on performance, intestinal morphology and on microbiota of 21-to-35-day-old piglets. A total of 160 commercial crossbred piglets (males and females) with initial weight of 6.10±0.709kg were allotted in a completely randomized design with five treatments: Basal diet - Negative Control (NC); Basal diet + antibiotic (PC); Basal diet + mannanoligosaccharides (MOS); Basal diet + organic acids (OA), Basal diet + mannanoligosacharides + organic acids (MOS+OA), eight replicates and four piglets per experimental unit. The inclusion of additives in the diets had no effect (P>0.05) on the final average weight of piglets. Similarly, no effects (P<0.05) were observed on average daily feed intake and on average daily weight gain. The feed conversion improved (P<0.01) with the inclusion of additives in the diets compared to piglets fed with the NC. There was no effect (P>0.05) of the dietary additives on intestinal morphology and microbiota composition (enterobacteria and lactobacilli). Use of antibiotics, prebiotics, organic acids or prebiotics associated with organic acids in the diet improves feed conversion of piglets from 21 to 35 days of age. The additives have no major effects on piglets’ intestinal morphology and microbiota.

This study was carried out to investigate the performance of broilers fed graded levels of Dry Distilled Cassava with Soluble (DDCS). In a 28-day trial, one hundred and forty-four (144), 5-week old, un-sexed Arbor acre strain broiler chicks (average weight of 1.09±0.02 kg) were randomly allocated to four dietary treatments of wheat offal (WO) and DDCS (12% WO + 0% DDCS = 0% DDCS; 8% WO + 4% DDCS = 4% DDCS; 4% WO + 8% DDCS = 8% DDCS and 0% WO + 12% DDCS = 12% DDCS) in completely randomized design. Each treatment had 2 replicates of 18 birds each. Dry matter feed intake (FI g/day), daily weight gain (g/day) and total weight gain (kg) decreases with increase in the levels of DDCS, while the feed conversion ratio (FCR) increases with increase in levels of DDCS, respectively. However, there was no significant (P>0.05) differences in the carcass evaluation measured. It was concluded that DDCS could replace wheat offal in the diets of broilers up to 8% without significant difference in growth and feed intake without detrimental effects on carcass quality of the birds.     Cette étude a été réalisée pour étudier la performance des poulets de chair nourris à des niveaux échelonnés de manioc distillé sec avec soluble (le 'DDCS'). Dans un essai de 28 jours, cent quarante-quatre (144) poussins de chair de la souche Arbor acre non sexés de 5 semaines (poids moyen de 1.09 ± 0.02 kg) ont été répartis au hasard dans quatre traitements diététiques d'abats de blé (WO) et DDCS (12% WO + 0% DDCS = 0% DDCS ; 8% WO + 4% DDCS = 4% DDCS ; 4% WO + 8% DDCS = 8% DDCS et 0% WO + 12% DDCS = 12 % DDCS) dans une conception complètement aléatoire. Chaque traitement comportait 2 répétitions de 18 oiseaux chacun. L'apport alimentaire en matière sèche (FI g / jour), le gain de poids quotidien (g / jour) et le gain de poids total (kg) diminuent avec l'augmentation des niveaux de DDCS, tandis que le taux de conversion alimentaire (FCR) augmente avec l'augmentation des niveaux de DDCS, respectivement. Cependant, il n'y avait aucune différence significative (P> 0.05) dans l'évaluation de la carcasse mesurée. Il a été conclu que le DDCS pouvait remplacer les abats de blé dans l'alimentation des poulets de chair jusqu'à 8% sans différence significative de croissance et de consommation alimentaire sans effets néfastes sur la qualité de la carcasse des oiseaux.

Abstract Our aim, with this study was to evaluate the consumption, performance, quantitative characteristics of carcasses, biochemical profile, plasma levels of ghrelin and leptin, expression of the receptor for ghrelin (GHS-R1a) in the hypothalamus and duodenum, and the number of goblet cells in the duodenum of calves subjected to milk volume restriction and supplemented with 2-hydroxy-4-(methylthio)butanoate acid (HMTBa). We used 21 Holstein-mixed breed calves, aged between 3 and 15 days with an average weight of 36.8 kg, and housed in pens with troughs for hay, concentrate, and water. The study included two consecutive experimental periods (P1 and P2) of 21 days each, with seven days of adaptation to the diet and facilities. The calves were distributed in a completely randomized design in three treatments with seven repetitions. 1 - Control: 6 L of milk/day during P1 and 6 L of milk/day during P2; 2 – RES (milk restriction): 3 L of milk/day during P1 and 6 L of milk/day during P2; 3 - RES + HMTBa: 3 L of milk/day during P1 and 6 L of milk/day during P2 + 3.3 g of HMTBa/day in both periods. HMTBa was supplied in milk, and the amount of concentrated ration and hay provided and leftovers were recorded daily to estimate dry matter (DM) and crude protein (CP) consumption. Mean daily weight gain (DWG), final weight (FW), and feed conversion (FC) were obtained at the beginning and at the end of each 21-day period. Plasma concentrations of ghrelin and leptin, triglycerides, total protein, urea, lactate, creatinine, alkaline phosphatase, and cholesterol were measured for P1 and P2 at the end of each 21-day period. At the end of P2 animals were slaughtered; sections of the duodenum were collected to evaluate the expression of GHS-R1a and quantity of goblet cells; hypothalamus was used to evaluate the expression of GHS-R1a; rumen was used to evaluate the thickness of epithelium, keratin, density, and height and width of ruminal papillae. In P1, total DM consumption, FW, DWG, glucose and triglycerides were lower in the RES and RES+HMTBa groups (P &lt; 0.001). In P2, there was an improvement in the FC of the RES+HMTBa group (compared to Control and RES) and a lower urea concentration in the RES group (compared to Control and RES+HMTBa) (P &lt; 0.001). No differences were observed among groups regarding hormonal concentrations, histological parameters, and GHS-R1a expression in the duodenum and hypothalamus. Therefore, milk restriction combined with HMTBa supplementation promoted greater compensatory gain by a mechanism independent of changes in GHS-R1a expression and hormone levels of ghrelin and leptin.

This study was conducted to assess the effects of abattoir wastes (bovine blood and rumen content mixture) on the haematology and growth performance characteristics of broiler birds. One hundred and twenty (120) unsexed day old Abor acre broiler chicks were randomly assigned to 4 treatments and replicated 3 times in a completely randomized design (CRD) experiment. Four experimental diets were formulated to meet the nutrient requirement of broilers such that the birds were fed sundried abattoir waste (bovine blood and rumen content mixture) included at 0%, 5%, 10% and 15% representing Diet 1, 2, 3 and 4 respectively, with Diet 1 as the control. Each dietary treatment consists of 30 birds with 10 birds per replicate. The experimental diets and clean water were supplied at- libitum throughout the experimental period. Data were collected on feed intake, daily weight gain, final body weight, weight gain. Feed conversion ratios were calculated. Blood samples for hematology was collected, analyzed and recorded. At the end of the 56 days feeding trials, data collected on different parameters were subjected to analysis of variance (ANOVA). Results showed that mixtures of bovine blood and rumen content significantly (P<0.05) improved the final weight (1767.02g -1931.44g), weight gain (1367.02g -1528.44g), feed intake (107.47g -118.99g) and feed conversion ratio (4.87 – 4.08) of the broilers. Significant (P<0.05) improvements were observed on the RBC, WBC, MCV, MCH, eosinophyls and the lymphocytes of the haematological parameters of the broilers. These results showed the complementary potentials of bovine blood and rumen content mixture in broiler diets, which can be included up to 15% in the ration of broilers without detrimentally affecting the growth performance and haematology of the broilers.

In a 56-day feeding trial, an experiment was conducted to determine the effects of replacing maize with different levels of ensiled cassava root-leaf blends (ECRLB) on growth, carcass yield, blood profile and economics of production of weaner rabbits. Five experimental diets were formulated and fed to the animals; diet 1= a maize based diet (control diet), diet 2= 30% maize + 10% ECRLB, diet 3 = 20% maize + 20% ECRLB, diet 4= 10 % maize + 30% ECRLB, diet 5= 40% ECRLB. A total number of forty weaner rabbits with an initial average weight of 574.09g±20.03g were randomly allocated to the five dietary treatments in a completely randomized design (CRD) with eight animals per treatment. Data were collected on growth indices, economics of production, carcass characteristics and blood profile Increased (P<0.05) weight gain was observed as the percentage inclusion of ECRLB increased. Rabbits on diet 4 (10 % maize + 30% ECRLB) and 5 (40% ECRLB) recorded the highest (P<0.05) daily weight gain with a corresponding highest (P<0.5) final body weight. Similar FCR were recorded across the treatments Economics of production of animals on diets containing 30 and 40% ECRLB was the best (P<0.05). Carcass indices were not significantly (P>0.0) affected by the experimental diets. Rabbits fed ECRLB recorded lower (P<0.05) serum cholesterol and higher (P<0.05) serum glucose concentration compared to control. In conclusion dietary inclusion of ECRLB up to 40% improved performance and did not show any deleterious effects on all indices examined and is recommended.     Au cours d'un essai d'alimentation de 56 jours, une expérience a été menée pour déterminer les effets du remplacement du maïs par différents niveaux de mélanges racines-feuilles de manioc ensilées (le 'ECRLB) sur la croissance, le rendement de carcasses, le profil sanguin et l'économie de la production de lapins sevrés. Cinq régimes expérimentaux ont été formulés et nourris aux animaux ; régime 1= régime à base de maïs (régime de contrôle), régime 2= 30% maïs + 10% ECRLB, régime 3 = 20% maïs + 20% ECRLB, régime 4= 10% maïs + 30% ECRLB, régime 5= 40% ECRLB. Un nombre total de quarante lapins sevrés d'un poids moyen initial de 574,09 g±20,03 g ont été attribués au hasard aux cinq traitements diététiques dans une conception complètement randomisée (CRD) avec huit animaux par traitement. Des données ont été recueillies sur les indices de croissance, l'économie de la production, les caractéristiques de la carcasse et le profil sanguin. Le gain de poids accru (P<0,05) a été observé à mesure que l'inclusion en pourcentage de l'ECRLB augmentait. Les lapins de l'alimentation 4 (10 % de maïs + 30 % d'ECRLB) et 5 (40 % d'ECRLB) ont enregistré le gain de poids quotidien le plus élevé (P<0,05) avec un poids corporel final correspondant le plus élevé (P<0,5). Les 'FCR' similaires ont été enregistrés à travers les traitements Économie de la production d'animaux sur les régimes contenant 30 et 40% ECRLB a été le meilleur (P<0,05). Les Indices carcasse n'étaient pas significativement (P>0,0) affectés par les régimes expérimentaux. Les lapins nourris à l'ECRLB ont enregistré un taux de cholestérol sérique inférieur (P<0,05) et une concentration plus élevée de glucose sérique (P<0,05) par rapport au contrôle. En conclusion, l'inclusion alimentaire de l'ECRLB jusqu'à 40 % a amélioré les performances et n'a pas montré d'effets délétères sur tous les indices examinés et est recommandée.
