This study was conducted to compare the effects of using direct fed microbial (RE3) and antibiotics on the gut morphology. Two hundred and forty unsexed, one-day old Marshal strain broiler chicks were used for the experiment. The birds were randomly allotted into three dietary treatments with each treatment replicated four times at 20 birds per replicate making a total of 80 birds per treatment. The experimental design was completely randomized design. The villous height (9.303E2), the crypt depth (1.5053E2) and the muscular thickness (2.2311E2) of the RE3 treated birds were higher (P<0.05) when compared with birds fed with control diet (T1) 8.619E2, 1.3790E2 and 1.9645E2 and the control + antibiotics (T3) 7.0677E2, 1.3331E2 and 1.9027E2 respectively. The observations revealed that birds put on treatment 2 (RE3 probiotics) had better presentation and preservation of the intestinal villi, glands and intestinal wall integrity. It was concluded that supplementation of broilers diets with the direct fed microbial (RE3) will lead to maintenance of intestinal health and better utilization of nutrients to enable full expression of genetic potential.

The effect of phytobiotics inclusion on haematological and serum indices of broiler chickens was investigated using 180 one day-old Arbor-acre broiler chicks in an eight weeks feeding trial. Six experimental diets were formulated to include the control diets (Og/kg), Ginger (5g/kg), Pawpaw leaf (5g/kg), Moringa (5g/kg), Turmeric(1g/kg) and Oxytetracycline (0.5g/kg) diet. These diets were assigned to six groups of 30 chicks replicated 3 times with 10 birds per replicate in a completely randomized design (CRD). Feed and water were given ad libitum. At the end of eight weeks, blood samples were collected from jugular vein of the birds and were analyzed for haematological and serum biochemical indices. The result of the analysis showed that dietary treatments significantly (p<0.05) influenced all haematological parameters studied. Ginger had the highest value of packed cell volume (45%), haemoglobin (15.05 g/dl) and red blood cell count (3.39x1012L-1) at the finisher phase. Total protein, uric acid, glucose were significant (p<0.05). Serum cholesterol value was significantly (p<0.05) lower in birds supplemented with ginger compared to other groups. It can be concluded that ginger at 5g/kg improved PCV, Hb and reduction of cholesterol concentration in broiler chicken.

Deficit of conventional feed ingredients in meeting increased demand has led to an alarming hike in their prices culminating in sky rocketing cost of livestock feed. This has necessitated an urgent search for low cost and more readily available alternatives. This study was conducted to investigate the performance of broiler chicks fed diets containing graded levels of soaked and boiled Bambara nut seed meal (BNSM). One hundred and five (105), 2 week old broiler starter chicks were used for the experiment. The birds were randomly allotted into four dietary treatments with each treatments replicated thrice at seven birds per replicate in a completely randomized design. Five experimental diets were formulated containing processed BNSM designated as T1 (control diet with 0 % BNSM), while T2, T3, T4 and T5 had 5 % soaked BNSM, 10 % soaked BNSM, 5 % boiled BNSM and 10 % boiled BNSM, respectively. The experiment lasted for four (4) weeks. Feed and water were provided ad libitum. The results showed that birds fed processed BNSM diets had significantly (P<0.05) higher final weight and weight gain comparable to 702.38g and 19.99 g/bird/day in the control group. The values obtained from feed intake showed that T2 (64.74 g) had significantly (P<0.05) least value compared to other dietary treatments. Feed conversion ratio and feed cost per kg gain (N) were significantly (P<0.05) better in birds fed processed BNSM diets compared to 3.39 and N215.85 respectively in the control group. It was therefore concluded that processed BNSM improved performance of broiler chickens.     Le déficit d'ingrédients alimentaires conventionnels pour répondre à la demande accrue a conduit à une hausse alarmante de leurs prix, aboutissant à une flambée du coût des aliments pour le bétail. Cela a nécessité une recherche urgente d'alternatives peu coûteuses et plus facilement disponibles. Cette étude a été menée pour étudier la performance des poussins de départ de pouletsde chair nourris avec des régimes contenant des niveaux échelonnés de farine de graines de noix de Bambara trempées et bouillies. Cent cinq (105) poussins de départ âgés de 2 semaines ont été utilisés pour l'expérience. Les oiseaux ont été répartis au hasard en quatre traitements diététiques, chaque traitement étant répliqué trois fois à raison de sept oiseaux par réplique dans une conception complètement aléatoire. Cinq régimes expérimentaux ont été formulés contenant du 'BNSM'-Bambara nutseedmeal(Aliment de farine de graines de noix de bambara)- traité désigné comme T1 (régime témoin avec 0% de BNSM), tandis que T2, T3, T4 et T5 contenaient 5% de 'BNSM' imbibé, 10% de 'BNSM' imbibé, 5% de 'BNSM' bouilli et 10% de 'BNSM' bouilli, respectivement. L'expérience a duré quatre (4) semaines. L'alimentation et l'eau étaient fournies ad libitum. Les resultants ontmontré que les oiseaux nourris avec des régimes 'BNSM' transformés avaient un poids final et un gain de poids significativement plus élevés (P <0.05) comparables à 702.38 g et 19.99 g / oiseau / jour dans le groupe témoin. Les valeurs obtenues à partir de la consommation alimentaire ont montré que T2 (64.74 g) avait une valeur significativement moindre (P <0.05) par rapport aux autres traitements diététiques. Le taux de conversion alimentaire et le coût alimentaire par kg de gain (N) étaient significativement meilleurs (P <0.05) chez les oiseaux nourris avec des régimes 'BNSM' transformés par rapport à 3.39 et N215.85 respectivement dans le groupe témoin. Il a donc été conclu que le 'BNSM' transformé améliorait les performances despoussins de départ de poulets de chair.

A total of 225 day-old male broiler chicks (Ross-308) were randomly allocated to five treatment groups, with three replicates in a completely randomized design for 42 days. Birds were fed a basal-diet supplemented with: no additive (control-diet), multi-strain probiotic (Lactobacillus acidophilus, Lactobacillus casei, Enterococcus faecium and Bifidobacterium thermophilum), or 0.15, 0.20 and 0.25% ginger (Z. officinale) powder, respectively. The results show no significant differences among treatments for growth traits and carcass characteristics, whereas using probiotics and ginger at all levels resulted in a significant decrease of gizzard weight and abdominal fat compared to the control group. Dietary treatments did not affect blood biochemistry and antibody production against sheep red blood cells (SRBC), IgG and IgM; however, antibody titre was higher in birds fed 0.25% ginger than other diets after 7 days post injection. The Lactobacillus counts in ileal content of birds fed 0.20 and 0.25% ginger were higher compared to the other treatments. In conclusion, dietary supplementation with either ginger or probiotics showed a significant influence on birds’ immune response, probably because ginger had strong antioxidant activity and the probiotics stimulated the production of natural antibodies.

The effect of a prebiotic mannan oligosaccharides (Actigen™) supplementation for 35 days was analyzed on growth, carcass traits and blood physiology of broilers. A total of 360-day-old broilers distributed under completely randomized design into four treatment groups with 24 replicates of 15 birds each was fed with Actigen™ supplemented diets @ 0.2, 0.4 and 0.6 g/Kg and a control diet. Data for growth performance were collected weekly while slaughtering data at 35th day. Results showed that the birds fed with Actigen™ added diet @ 0.6 g/Kg exhibited improved livability% (98.88±1.11), feed intake (3391.68±38.70 g), body weight (2157.66±31.52 g), weight gain (2111.49±30.89 g), FCR (1.57±0.03), dressing% (72.28±0.40), breast yield% (29.58±0.05), thigh yield% (31.61±0.30) and blood biochemical parameters. Superior (P£0.05) antibody response against ND and IB were recorded in birds exposed to Actigen™ supplemented diet @ 0.6 g/Kg. It was concluded that Actigen™ supplementation @ 0.6 g/Kg corroborated to improve growth, carcass traits, blood biochemistry and antibody response in broilers.

The influence of feeding with starter diets containing spray-dried bovine colostrum (SBC), spray-dried bovine plasma (SBP), or spray-dried porcine plasma (SPP) on the growth performance and gut morphology of broiler chickens was investigated. The crude protein, lysine, and methionine plus cystine contents (g/kg as received) of SBC, SBP, and SPP were determined to be 766, 736, and 684; 58, 61, and 55; and 27, 28, and 24, respectively. The 3 test proteins were incorporated into a maize–soybean meal diet at a level of 50 g/kg and fed to 6 replicates of 8 male broiler chicks from 1 to 14 days of age. On Day 14, the experimental diets were replaced with a common grower-finisher diet, which was offered until Day 35. Dietary treatments had no effect (P > 0.05) on the weight gain or feed intake of birds during the first 14 days. However, feed/gain of birds fed the SBC diet was lower (P < 0.05) than of those fed the control diet. A trend for a reduction in feed/gain (P = 0.06) was observed in SBP and SPP diets. Dietary treatments had no effect (P > 0.05) on performance during Days 14–35 or Days 1–35. Villus height was increased by 5.7% (P < 0.05) and 4.6% (P = 0.05) in birds fed the SPP and SBP diets, respectively, compared with those fed the control diet. Crypt depth was 6% greater (P < 0.05) in birds fed the SPP diet and tended (P = 0.08) to be greater in birds fed the SBC diet, compared with birds fed the control. The ratio of villus height to crypt depth tended (P = 0.06) to be lower in birds offered the SBC diet compared with the control. Crypt goblet cell density was reduced (P < 0.05) by 13.9% in birds fed the SBC diet, compared with control birds. These results suggest that feeding with diets containing the SBC, SBP, and SPP during 1–14 days of age has some beneficial effects on broiler chickens. Further studies are needed to evaluate these products in less sanitary environments, which may increase the positive responses.

ABSTRACT The objective of this study was to evaluate the effects of probiotics and synbiotics on the performance and Enterobacteriaceae count of broiler chickens. A total of 640 one-day-old male broiler chicks were distributed in a completely randomized design with four treatments and eight replicates with 20 birds each. The treatments were: ration with performance enhancer (zinc bacitracin; positive control); ration without performance enhancer and probiotic/synbiotic (negative control); ration with probiotics; and ration with synbiotics. At 35 days, five birds from each treatment were euthanized and intestinal contents were harvested for determining the Enterobacteriaceae count. The performance data and average colony-forming units (CFUs) transformed as log CFU/g were subjected to analysis of variance and Tukey’s test. The effects of probiotics and synbiotics were observed in the initial phase, with supplemented birds exhibiting comparable weight gain to those supplemented with bacitracin. No effect of the treatment on broiler performance was observed after 42 days. The enterobacterial count was comparable among all experimental treatments. Supplementation with probiotics and synbiotics did not compromise the performance of broilers and did not alter the Enterobacteriaceae count.

Feeding trial experiment was carried out to evaluate the haematological and serum biochemical parameters of broiler chickens fed graded levels of Roselle Seed Cake (RSC) as replacement of a conventional protein source. Proximate composition was done to determine the nutrient content of RSC and experimental diets. The experiment contained graded levels of RSC replacing soya bean cake (SBC). One hundred and twenty (120) day old Ross broiler chickens were used in a Completely Randomized Design (CRD). The broiler chicks were assigned to five dietary treatments with three replicates each with 8 birds per replicate and 24 birds per treatment. Five isonitrogenous and isocaloric diets were formulated for the broiler straight diet. Diet 1 served asthe control diet while diets 2, 3, 4 and 5 contained 8%, 16%, 24% and 32% RSC respectively. Data were collected and analyzed using analysis of variance and the mean was separated using Duncan multiple range test. The findings from the study showed that there were no significant (P?0.05) differences in all the parameters measured for haematology across dietary treatment means except for the white blood cell. The blood biochemical composition showed no significant (P?0.05) differences in total protein, high density lipoprotein, low density lipoprotein and creatinine across dietary treatments. RSC as an alternative feedstuff can replace soya bean cake at 24% in the diet of broiler chickens for improved haematological and blood biochemical of broilers. Roselle seed cake can replace SBC at the broiler chicken straight ration at 75% (24% dietary RSC) inclusion for better performance.

The bioavailability of phosphorous, and blood serum and rumen liquor P level was studied in indigenous growing cattle by feeding bone meal and Triple Super Phosphate (TSP) with control diet. Nine indigenous growing cattle (live weight of 164 ± 21 kg) were randomly assigned in a Completely Randomized Design (CRD) to three dietary treatments, consisted of a basal diet (T0) of 0.16% P and experimental diets supplemented with bone meal (T1) and triple super phosphate (T2) to provide P level of 0.44%. All diets were formulated to be iso-nitrogenous and iso-caloric. Three cannulated animals were used for rumen liquor P level study by feeding three diets. Apparent absorption and balance of P were significantly (P<0.01) higher in T1 and T2 diets than that of diet T0, but true absorption did not differ significantly (P>0.05). Bioavailability of P of control diet (37.41%), bone meal (81.45%) and triple super phosphate (80.49%) were significantly differed (P<0.01). Rumen liquor and blood serum P level differed significantly (P<0.01). Supplementation of bone meal and triple super phosphate results in high blood serum P (P>0.05) with no difference between bone meal and triple super phosphate. The results suggested that the bioavailability of P from bone meal and TSP was high and dietary supplementation of P with bone meal and TSP improved P retention and blood serum P level.
