Abstract The aim of this study was to evaluate the effect of phytogenic additives and glutamine plus glutamic acid, associated or not, on histomorphometry of bursa of Fabricius and small intestine, oocyst count and lesion scores, and carbon turnover of duodenal mucosa of broiler chickens infected with Eimeria acervulina. A total of 450 male broiler chickens was distributed into a completely randomized design with six treatments and three replications. Treatments consisted of control diet (CD); CD + coccidiosis vaccine; CD + antibiotic performance enhancers and anticoccidial (APE/AC); CD + glutamine and glutamic acid (Gln/Glu); CD + phytogenic additives (PA); CD + Gln/Glu + PA. Birds on treatment CD + vaccine were vaccinated via drinking water at three days of age against coccidiosis. At 16 days of age all birds of all treatments were inoculated orally and individually with 500,000 oocysts of Eimeria acervulina. There was no treatment effect on lesion score in the intestinal epithelium of birds. The smaller number of excreted oocysts was observed in groups of birds fed diets containing APE/AC and PA. Were observed better results of villus height and crypt depth for duodenum and ileum of birds of treatments containing Gln/Glu at 7 days of age, and Gln/Glu and PA at 21 days of age. Higher percentage of cortical area from bursa follicles was observed in birds fed diets supplemented with Gln/Glu and PA at 7, 14 and 21 days of age. Increased turnover of intestinal mucosa was observed in treatments containing Gln/Glu, indicating acceleration in development and regeneration of damaged tissue. Glutamine plus glutamic acid and phytogenic additives can provide improvements to structure, and thus to intestinal function, as well as to better immune response against the infectious challenges. Phytogenic additives can be used for coccidiosis control of broiler chickens where the use of antibiotic performance enhancers and anticoccidials is prohibited.

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.

Two hundred and twenty five, day-old Arbour Acre broiler birds were use to investigate the effect of graded dietary levels of Parkia biglobosa pulp meal (PBPM) on the performance, haematological and carcass parameters of the birds from 0-8 weeks of age. Five isocaloric and isonitrogenous diets were formulated to contain PBPM at 0,10,20, 30 and 40 percent respectively making a total of 5 treatments. Each treatment was replicated three times with 15 birds per replicate in a completely randomized design experiment. Feed and water were supplied ad libitum. Records taken included weekly weight changes and weekly feed intake. There was no record of mortality throughout the duration of the experiment. Results obtained showed a decrease in the bird’s performance as the dietary levels of the pulp increased. The final weight (g/b) and weight gain (g/b/day) decreased from 2122 and 33.91 for the control to1309 and 20.97 for the 40% inclusion level of PBPM meal respectively However birds placed on 10% dietary level had a performance that were not significantly (P>0.05) different from those placed on the control diet which were on standard broiler starter and finisher rations. Also it was observed that values obtained for the haematological parameters fall within the range often reported for healthy birds indicating that the pulp did not impart any deleterious effect on the health of the birds. It can be concluded that broiler chickens can be fed up to 10% dietary level of PBPM without adverse effect on the performance of the birds.

<p>This experiment was conducted to investigate the efficacy of methyl groups donor of betaine to spare methionine based on performance and carcass in broiler chickens. In total, 100 day old broiler chickenss were used in this experiment. They were allocated to 4 dieaty treatmants in 5 replicates with 5 broilers each. The basal diet was deficient in methionine. The control diet was obtained from basal diet supplemented with methionine to meet the requirements 5 g/kg diet for starter period and 3.8 g/kg diet for finisher period. The rest 3 treatments were basal diet deficient in methionine supplemented with 1, 2 and 3 g betaine per kg diet. The variables that were observed included average daily gain and carcass characteristics. The data were than analyzed by analysis of variance of Completely Randomized Design and continued with Dunnet test. The result indicated that supplementation of 1 and 2 g betaine per kg diet deficient in methionine resulted the broiler performance which was not different with supplementation of methionine. Accordingly, carcass characteristics for broilers fed diet supplemented with methionine were not different with that supplemented with betaine, which indicated that betaine may reduce the methionine level in the broiler diet. It can be concluded that betaine spares metionine in broiler diets.</p>

Mineral chelators such as organic acids have been reported to compete favourably with phytate by forming soluble complexes with feed minerals. Effect of feed grade acidifiers on total tract mineral retention and intestinal pH of broiler finisher chickens was investigated. A total of 300-broiler finisher chickens were assigned to four treatment groups. Each treatment was replicated thrice with twenty chickens per replicate in a completely randomized design. The control treatment (T1 ) was fed the control diet adequate in available phosphorus at 0.5% while other treatments (T2 -T4 ) were fed sub-optimal available phosphorus diets at 0.4%. Three blends of acidifiers; Fysal®, Orgacid® and Acidomix® were supplemented in the diets of chickens in treatments 2, 3 and 4 at 0.1% (1kg per ton/feed). Chickens fed diet supplemented  with Fysal® showed the best (P<0.05) results in total tract mineral retention 56.5+/-5.75 compared to the control and other treatments. The poor mineral retention i.e. 35 and 46% for calcium and phosphorus respectively by chickens fed the control diet was attributed to the insoluble phytate-mineral complex that limits mineral bioavailability. Intestinal segments of chickens fed acidified diets showed significant reduction (P<0.05) in pH in the range of 5.26-7.16 across duodenum to ileum compared to the control group 6.83-8.76. It is concluded that feed acidification at 0.1% improves mineral utilization in broiler chickens as it competes favourably with phytate in the lumen of the gut leading to better nutrient utilization.

This study was aimed at evaluating the nutritive value of different sources of energy in broiler chicken diets on the growth performance and haematological parameters of broiler chickens. Five isonitrogenous and isocaloric diets (23.17% CP; 2831 Kcal/ME; 21.73% CP; 2929Kcal/ME) for the broiler starter (0-4 weeks) and finisher phases (5-8 weeks), respectively were formulated. Treatment 1 is the control diet while treatments 2, 3, 4 and 5were sorghum, pearl millet, cassava and sweet potatoes based diets, respectively. A total of 225, 1 day-old NAPRI X broiler chicks were randomly allotted to the five treatments with three replicates each in a Completely Randomized Design (CRD). Data were subjected to ANOVAα0.05 . The results showed that final bodyweights (503.44 g and 2302.77 g), feed intake (819.67 g and 3073.70 g) and weight gained (453.61 g and 1892.07 g) were significantly (P

Haematological Indices

An eight-week feeding trial was conducted to evaluate the effect of substituting maize with indomie waste meal on the haematology and serum biochemical indices of 90-dayold Anak 2000 broiler chickens. Three experimental broiler starter and finisher diets were formulated with diet 1 serving as control containing 0% Indomie waste meal (IWM), while diets 2 and 3 contained IWM at 50 and 100% inclusion levels for maize. The chicks were randomly assigned to the three treatment diets (1, 2 and 3) in a completely randomized design and each treatment group contained three replicates with ten chickens per replicate. The result on the haematological indices revealed that MCV values were significantly influenced (p<0.05) by the treatment diets with highest value of (135.50±0.21fl) among birds fed 50% IWM. MCH also significantly varied(p<0.05) among birds fed the treatment diets with highest (42.77±0.31pg) recorded among birds maintained on the control diet. Serum biochemical indices revealed that phosphorus value were significantly higher (p<0.05) in birds fed the control diet with the mean value of 3.63±0.09mg/100ml. Total cholesterol was significantly higher (p<0.05) in birds fed 100% IWM. The overall results from this study conclusively suggest that the inclusion of indomie waste meal in the diet of broilers up to 100% did not have any detrimental effect on the blood profile of the birds. But precaution had to be taken in the incorporation of IWM at this level because of the increase effect on the cholesterol level of the blood.Mr. Omoikhoje, B. (Laboratory Technologist)

This study was designed to investigate the effects of Thymus vulgaris (thyme) and Mentha pulegium (mentha) powders on meat colour, nutrient composition and malondialdehyde (MDA) where broiler chickens were under heat stress. Two hundred one-day-old male chicks were used in a completely randomized design with four treatments and five replicates each (10 birds per replication). Treatments were the control diet, 0.5% mentha, 0.5% thyme and 0.5% mixture of the two plants. The results showed no effect of dietary supplements on thigh meat redness and yellowness. Both plant products diminished the thigh lightness significantly compared with the control. No significant differences between treatments were observed for the ash, ether extract and crude protein content of the thigh muscle. Supplementation of thyme and mentha separately or together increased the moisture of the thigh muscle significantly, compared with the control. The combination of the plant products resulted in a higher thigh pH and significantly lower malondialdehyde (MDA) concentration in the thigh muscle compared with the control. In conclusion, dietary supplementation of thyme and mentha separately or in combination improved the meat quality of broiler chickens under heat stress through decreasing the MDA concentration and increasing the pH and moisture content of the thigh muscle

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.

This work aimed to determine the nutrient intake and quantitative aspects of sheep carcass from three different genetic groups. Eighteen animals with initial average body weight of 20.1kg were used in a completely randomized design, in a factorial 3x2 scheme (three different crossbreeds - 6 F1Dorper x non defined breed, 6 F1Somalis x non defined breed and 6 F1Santa Inês x non defined breed versus two diets). The diets fed to the animals were formulated with or without cashew nuts. The inclusion of cashew nut meal in the diet influenced nutrient intake. Differences of intake among the animal groups were observed as higher intake for F1Dorper x non defined breed (NDB), followed by F1Somalis x NDB and for F1Santa Inês x NDB. However, the control diet produced no difference among these genotypes. The average daily gain was lower for both crossbreeds when cashew nut meal was added in the diets. The evaluated crossbreeds and diets did not affect the feed:gain ratio. The carcasses analyses showed that the inclusion of cashew nut meal in the diets reduced the cold carcass weight and the rib weight. The addition of cashew nut meal in the diets for lambs reduces food intake and carcass yield. The crossbreed F1Dorper x NDB presented the higher rate of average daily gain.

The objective of this study is to evaluate the influence of five feed restriction programs (FRP) on broiler performance and carcass yield. 425 Cobb 500® broilers were distributed in a completely randomized design with five FRPs and five replicates with 17 broilers. The FRPs were: Program 1 (P1): consumption ad libitum (AL) of control diet from 14 to 42 days; P2: quantitative restriction (QTR) of 10% of AL consumption from 14 to 28 days and AL consumption from 29 to 42 days; P3: AL consumption from 14 to 28 days and QTR from 29 to 42 days; P4: qualitative restriction (QLR) of 10% of the level of crude protein and essential amino acids from 14 to 28 days and AL consumption from 29 to 42 days; and P5: AL consumption from 14 to 28 days and QLR from 29 to 42 days. The broilers of the AL treatment gained more weight (p≤0.01), but had a similar FCR (P>0.05) compared to broilers submitted to QTR from 29 to 42 days. In addition, broilers fed QTR from 14 to 28 days presented a lower FI and a better FCR (p≤0.01) in relation to broilers fed QLR of 14 to 28 (P4) and 29 to 42 days (P5). The broilers fed QTR of 14 to 28 days diet presented a similar FCR as broilers fed AL. The 10% reduction in AL consumption of 14 to 28 d is a viable economical alternative to feed broilers up to 42 days of age.
