This study aimed at investigating the effect of by-products of palm kernel extraction; palm kernel extraction residue (PKER) and palm kernel sludge (PKS) based diets as replacement for maize in broiler diets. A total of 198 one-day old Marshal Broiler chickens were randomly assigned to six dietary treatments. Each dietary treatment had 33 birds with 11 birds per replicate. Maize in the diets was partly replaced by PKER and PKS each at three levels (0, 10 and 20%). The experiment was conducted in both starter and finisher phases. Growth responses, carcass evaluation and nutrient utilization were estimated. Data obtained were subjected to 2x3 factorial arrangement within the completely randomized design (CRD). Feed: Gain was influenced by the level of the palm kernel by-products during 1-28days of study. The weight gained during the 56 days period were not significantly higher (P>0.05) across the treatments All the carcass parameters measured were not significantly (P>0.05) affected by either PKER or PKS. However birds on PKER diets showed superior (P<0.05) nutrients use. In conclusion, the inclusion of palm kernel extraction by-products (between 10-20% PKER and 20% PKS) in the diets of broiler chickens is thereby encouraged for better growth and efficient feed utilization.

An experiment was carried out to determine the effect of different organic acids (OAs) on carcass yield and internal organ characteristics of broiler chickens. The OAs were ethanoic acid (acetic acid - AA), butanoic acid (butyric acid - BA), citric acid (CA) and methanoic acid (formic acid - FA). One hundred and fifty (150) day old AborAcre-plus chicks were used. There were five dietary treatments. Diet 1 which served as control (CON) contained no OAs, while 0.25% of AA, BA, CA and FA replaced palm kernel cake in diets 2 – 5. Each treatment was replicated three times with 10 birds per replicate, arranged in completely randomized design (CRD). Diets were both isoenergetic and isonitrogenous. The experiment lasted for 4 weeks during the finisher phase. Feed and water were given ad libitum. At the end of 4 weeks, 3 birds from each replicate giving a total of 9 birds per treatment were slaughtered for carcass and internal organ evaluation. Result from the carcass evaluation showed that dressed carcass, breast, thigh, wing and drumstick of OA treated groups were not significantly (P>0.05) different from the control. The backcut was significantly (P<0.05) heavier in control than in AA and CA. Abdominal fat in birds fed OAs was statistically similar to the control. The liver weight was significantly (P<0.05) reduced by BA and FA while the weight of spleen was reduced (P<0.05) by all the OAs. The caecum and the large intestine were significantly (P<0.05) enlarged in the control. There was non effect (P>0.05) on other internal organs.

This study was conducted to determine and compare digestible energy (DE) and metabolizable energy (ME) values and the apparent total tract digestibility (ATTD) of energy and nutrients in eight ingredients fed to both growing pigs and sows. Two experiments with 48 crossbred barrows or six non-pregnant sows were allotted to eight treatments in a completely randomized design or a pseudo Latin square with six replicated pigs per dietary treatment. The dietary treatments were formulated with two cereal ingredients: corn and wheat; two ingredients with a high protein level and a low fiber level (HPLF): soybean meal (SBM) and cottonseed meal (CSM); two ingredients with medium protein level and medium fiber level (MPMF): corn distiller’ dried grains with solubles (DDGS) and corn germ meal (CGM); and two ingredients with a low protein level and a high fiber level (LPHF): wheat bran (WB) and palm kernel meal (PKM), respectively. Adult sows had greater DE and ME values and ATTD of energy and nutrients when fed cereal ingredients compared with growing pigs, and had lower DE and ME contents and ATTD of energy and nutrients except for acid detergent fiber (ADF) when fed HPLF ingredients compared with growing pigs. Moreover, no differences were observed between adult sows and growing pigs in DE and ME contents and ATTD of energy and nutrients when fed MPMF and LPHF ingredients, except that adult sows showed a greater ATTD of crude protein (CP) when fed MPMF ingredients compared with growing pigs. Our results indicate that sows had a lower available energy and nutrient digestibility when fed SBM or CSM compared with growing pigs. Crude protein contents in ingredients should be considered when predicting DE and ME values in sows based on the DE and ME values measured from growing pigs.

Cake of shea nut is an agroforestry by-product and residue after fat extraction from shea nuts for fat with no economic value and its increasing output has become an environmental issue lately. A 30-day study was conducted to investigate the apparent nutrient digestibility and carcass yield of broiler chicken fed cooked cake of shea nut diets of different fermentation periods. A total of 144 unsexed Arbor Acres Plus day-old broiler chickens were divided into four dietary treatments with four replicates of nine birds each in a completely randomized design. The results showed that fermentation enhanced the nutrient profile of cake of shea nut meal especially concerning crude protein and crude fiber as compared to raw cake of shea nut meal. The treatment values for crude protein and crude fiber digestibility showed significant (p < 0.05) differences amongst the dietary treatments while other nutrient parameters measured were not significantly (p > 0.05) different. There was no significant (p > 0.05) difference amid the treatment means for the control (carcass, breast and liver yield) and the carcass, breast and liver yield of broiler chickens fed diets containing different periods of fermented-cooked cake of shea nut meal.

An experiment was conducted to determine the effect of four organic acids (acetic, butyric, citric and formic acids) inclusion in the diets of broilers on growth, nutrient digestibility and faecal moisture. One hundred and fifty one day old Arbor-Acre - plus chicks were used. There were five dietary treatments. Basal diet which served as control contained no organic acid was formulated, while diets 2, 3, 4 and 5, respectively contained 0.25% acetic, butyric, citric and formic acids formed by adding 0.25% of each acid to the basal diet. Each treatment was replicated three times with 10 birds per replicate, arranged in completely randomized design (CRD). Diets were both isocaloric and isonitrogenous. The experiment lasted for 4 from the fourth to the eight week. Feed and water were given ad libitum. There were no significant differences (P>0.05) in live weight, daily gain, feed intake, feed: gain ratio and protein efficiency ratio. Acetic acid significantly (P<0.05) increased water intake. Fecal moisture was significantly reduced by citric and butyric acids. Higher crude protein digestibility was achieved by butyric acid (69.98%) citric (69.67%) and formic acid (71.33%) than the control (63.75%). Digestibility of CF, EE and ash was significantly (P<0.05) higher in all the organic acid groups. Feeding of diets treated with 0.25% of the test organic acids at the finisher phase, in that despite improved digestibility of nutrients the practice should not be encouraged for reasons of insignificant growth performance.

The increase in human population, particularly in the developing countries like Nigeria and the demand for animal protein intake has necessitated different approaches of solving protein shortage. A 28-day study was carried out to determine the performance of finishers fed on different hourly soaked doum palm (Hyphaene thebaica) pulp meal (DPPM) diets. Two hundred and sixteen (216) finishers (4 week-old) were randomly allotted to six dietary treatments. Each treatment consisted of 36 birds with three replicates (12 birds per replicate) in a completely randomized design (CRD). Six experimental diets were formulated and designed as follows: T1 (Control) contained 0% DPPM while T2, T3, T4, T5 and T6 contained 12.5% each of 2, 4, 6, 8 and 10 hours soaked DPPM as substitute for maize, respectively. Feeds and water were provided ad libitum for all treatment groups. The average body weight gain (40.44- 42.71 g/b/d), average feed intake (87.52-96.73 g/b/d) and feed conversion ratio (2.14-2.34) were non-significant (p>0.05) regardless of the dietary treatments. Statistical differences (p<0.05) were observed in some carcass parameters such as thigh (13.40-14.98%), neck (5.32-6.55%), shank (3.81-5.2 %), wing (9.80-11.41%), head (2.43-3.74%) and two haematological indices; white blood cell (160.67-189.53 X 103/mm3) and eosinophils (0.33-2.00%) across the treatment groups. The processed DPPM could serve as a rich energy source in broiler feeds with the raw doum palm pulp containing 2987.45 kcal/kg. Also, soaking the pulp for 2 to 10 hours before been included in broiler diet improved the nutritional content, acceptability, palatability and utilization of the feed by the broilers. Thus, up to 12.5% processed DPPM can be included in the diets of broiler chickens without adverse effect on growth performance, nutrient digestibility, carcass characteristics and haematological indices of chickens.

The effect of raw jackfruit (Artocarpus heterophyllus) seed meal (JFM) on performance, nutrient utilization and economics of production was investigated using 144 broiler chickens.The birds were divided into four dietary treatments of 3 replicates and 12 birds per replicate in a completely randomized design. Diet one was soybean based (control) while raw JFM meal was added to diets 2 (T ), 3 (T ) and 4 (T ) at 10, 20 and 30% levels of inclusion 2 3 4 of soybean meal in the control diet respectively. At 8 weeks, 2 birds per replicate were used to evaluate nutrient utilization. The growth performance was generally depressed with increased inclusion of raw JFM in the diets. The feed to gain ratio of birds placed on control diet (2.55) and T (2.56) were the same (P>0.05) and are significantly better (P < 0.05) than 2 other treatments. Nitrogen, ether extract and ash retention were virtually the same for birds fed T T and T while energy retention was higher (P<0.05) in birds fed T (2,82MJ/Kg ME) 1, 2 3 1 than those fed T , T and T .The cost per Kg feed was higher in T (? 131.59) and decreased 2 3 4 1 with increase in inclusion of raw JFM; T (? 127.17), T (? 123.66) and T (? 123.24). Cost per 2 3 4 Kg weight gain, revenue and gross margin were the same for birds fed control and those fed with T . From the foregoing raw JFM is a potential feed resource and could be included in the 2 diet of broiler chicken up to 10% level of inclusion of soybean meal in a control diet.

An experiment was conducted to determine the effect of different organic acids (OAs on carcass yield and internal organ characteristics of broiler chickens. The OAs were acetic acid (AA) butyric acid (BA), citric acid (CA) and formic acid (FA). One hundred and fifty (150) day old AborAcre - plus chicks were used. There were five dietary treatments. Diet 1 which served as control (CON) contained no OA, while diets 2, 3, 4 and 5 respectively contained 0.25% AA, BA, CA and FA which replaced palm kernel cake in which each treatment was replicated three times with 10 birds per replicate and arranged in completely randomized design (CRD). Diets were both isoenergetic and isonitrogenous. The experiment lasted for 8 weeks. Feed and water were given ad libitum. At the end of the 8 weeks of feeding, 3 birds from each replicate giving a total of 9 birds per treatment were slaughtered for carcass and internal organ evaluation. Result from the carcass evaluation showed that there were no significant differences (P>0.05) in dressed carcass weight, thigh, wing and drumstick. All the OAs except BA produced bigger breast meat compared to the birds fed control diet. The weight of the backcut was significantly (P<0.05) reduced by FA compared to the birds on control diet. Birds that consumed FA treated diet deposited more abdominal fat and AA produced the least (P<0.05). Internal organ result indicated that both the liver and the kidney were not negatively affected by OA treated diets. Caecum and the large intestine were significantly larger in than those obtained from birds fed the control diet. Therefore, addition of the OAs except BA to broiler diets could be a good practice considering their positive effect on the breast meat which is a premium cut part.

This study was aimed to determine the effects of protease supplementation in diets with agricultural-livestock by products on the growth performance in broiler chickens. The commercial protease used in current study was produced by Bacillus licheniformis which based on keratinase. The treatment diets were a control basal diet without agricultural-livestock by-products and protease supplementation (P1); P1 + 0.05% protease; basal diet with meat bone meal (MBM) and distiller’s dried grain with soluble (DDGS) suppementation (P3); P3 + 0.05% protease (P4); basal diet with hydrolized chicken feather meal (HCFM) and DDGS supplementation (P5); P5 + 0.05% protease. The obtained data were statistically analyzed using Complete Randomized Design, and analyzed subsequently by Orthogonal Contrats Test. Results showed that protease supplementation in the diets containing agricultural-livestock by-products did not affect growth performance of broiler chickens in starter phase and overall age phase. However, in diets containing MBM, protease supplementation reduced the nett gain and feed conversion ratio (FCR) in finisher phase (P<0.05). In diets containing HCFM, protease supplementation increased nett gain and FCR (P<0.05), compared to those of containing MBM. It could be concluded that qualified HCFM, MBM, and DDGS can be used as alternatives for protein-energy source feed stuffs in starter phase, as they did not reduce growth performance of broiler chickens. Protease used in this study might be more effective in diets containing HCFM than those of containing MBM and DDGS.Keywords: Agricultural-livestock by-products, Broilers chickens, Growth performance, Protease.

This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) and protein resources (soy or rapeseed meals) on gut morphology and protein digestibility of broiler chickens. Three hundred eighty-four male Ross-308 broiler chickens were used with a 23 factorial arrangement with treatments according to a completely randomized design. The morphological examinations of the intestine were carried out on 1-cm long excised segments from duodenum, jejunum and ileum. Adding wheat to the diet increased small intestine length in birds compared to other feedstuffs (P <0.05). Duodenum crypt depth and jejunum villi length were also higher in groups fed with rations containing wheat (P <0.05). Groups that received thyme essential oil and enzyme supplementation had increased length of the duodenum (P <0.05). However, the two- and three-factor interaction effects were not significant. Protein digestibility was not affected by treatment (P >0.05). Feeding wheat to broiler chickens may increase the surface area for nutrient absorption in the small intestine as compensation for the anti-nutritive activity of non-starch polysaccharides in wheat-based diets. Wheat based diets are expected to be acceptable for broilers when supplemented with appropriate enzymes or thyme essential oil.
