One hundred and twenty 5-week old Shaver Cross broiler chickens were randomly distributed to four dietary treatments in which Leucaena leucocephala seed meal (LSM) replaced groundnut cake at levels of 0, 5, 10 and 20% for an eight week period. Control and 20% LSM diets significantly (P<0.05) increased mean feed intake during the finisher phase. Feed conversion ratio (FCR) of birds on 20% LSM was significantly (P<0.05) lower than FCR of those on the rest of the treatments during the grower phase, while in the finisher period, broilers on 0 and 20% LSM had significantly (P<0.05) lower FCR than birds on Sand 10% LSM; the 10% LSM, however, induced significantly (P <0.05) higher FCR than 5% LSM during the same period. Average weight gains and mortality showed no significant treatment effects throughout the period of study. There were significant (P<0.05) differences between treatments meant for dressed carcass percentage, liver, kidney, intestine and gizzard weights as percentage liveweight. Based on the data obtained in this study, LSM should not be included in broilers' diets at levels more than 10% of the groundnut cake.

  The study was conducted to determine the effect of graded levels of differently processed Roselle (Hibiscus sabdariffa) seed meal on the performance and carcass characteristics of broiler chickens. One hundred and fifty (150), 28-day old birds were randomly allotted to 5 dietary treatments of 3 replicates of thirty birds each. Each replicate had 10 birds. The treatments were: T1 - control diet with 0% inclusion level of Roselle Seed Meal (RSM) while the four other diets had 50% of raw (T2: rRSM), soaked (T3: sRSM), boiled (T4: bRSM) and  fermented (T5: fRSM) Roselle Seed Meal in a complete randomized design. At the end of the 28thday of the feeding (week 8), parameters measured were on performance and carcass characteristics. The data collected were analyzed using ANOVA of SAS with the means, where significant, were separated using the Duncan's Multiple Range Test. Final weight (FW) and weight gain (WG) were highest in birds on T5. Birds on T5 had the least feed conversion ratio (FCR) value (2.62). Feed intake and percent mortality did not differ significantly among birds on the different dietary treatments. Birds on T5 had significantly (p < 0.05) higher values for live weight (LW), thigh weight (TW) and neck weight (NW). Percentage eviscerated weight, breast weight, drumstick weight, shank weight, wing weight and back weight did not differ significantly among the birds on the different treatments. The gizzard (G), liver (L) and spleen (S) had the highest values in birds on T3 (G: 2.53%), T1 (L: 2.34%), T5 (S: 0.18) being significantly (p<0.05) different from T 5 (G: 2.04% and L: 1.87%), T2 (S: 0.08%), T3 (S: 0.08%) and T4 (S: 0.09%) respectively. There were no significant (p>0.05) differences observed among the treatments for percentage heart weight. It can be concluded that processing methods enhanced the utilization of Roselle seed meal with the best being the fermentation method as revealed by its feed conversion ratio, live weight and some carcass parameters when Roselle Seed Meal was substituted for 50% of soybean meal in the broiler finisher diets.

This study was conducted to investigate the effect of dietary copper and probiotic supplementation on growth performance and carcass characteristics of broiler Chickens. A total of 180-day old marshal broiler chicks of mixed sex were randomly allotted to six treatment groups of 30 birds each. The Treatments were divided into three replicates of ten birds each; starter and finisher diets were formulated and fed for a period of fifty-six days. The dietary treatments were subjected to completely randomized design experimental layout which was made up of probiotic (0 and 500ppm) and copper (0, 125 and 250mg).The chicks were fed the broiler starter diet for the first 28 days and broiler finisher for the last 28 days. Treatment effect on broiler body weight, feed intake and feed conversion ratio were determined on a weekly basis. Data obtained were analyzed using analysis of variance (ANOVA) and, Duncan's Multiple Range Test was used to separate significant means. Dietary supplementation of copper and probiotic had no significant (P> 0.05) effect on final weight (FW), daily weight gain (DWG), feed intake (FI), and feed conversion ratio (FCR) at the starter phase of the experiment. However, at finisher phase, inclusion of probiotic resulted in higher significant (P < 0.05) values for FW (2214.12g/b) DWG (60.22g/b/d), FI (159.02g/b/d), and FCR (2.64). The carcass yields of the broilers were significantly (P< 0.05) influenced by copper and probiotic supplementations. However, lower value (1.07%) was obtained for abdominal fat in broilers fed 250mg Cu/kg supplemented diet. The study concluded that supplementation of copper and probiotics resulted in improved growth performance and carcass yield of broiler chickens.

This study was conducted to determine the growth performance and profitability of broilers chicken with vermi meal supplementation under a total confinement management system. A total of 60 broiler chickens were randomly distributed to four dietary treatments: T1= commercial feed (CF), T2= CF+2% vermi meal (VM), T3= CF+3% VM, T4= CF+5% VM inclusion in a completely randomized design. Feed conversion ratio was not significantly influenced by VM supplementation. However, the highest feed intake was recorded in broilers fed CF supplemented with 2% VM (T2) while control broilers fed only CF (T1) had the lowest feed consumption. Broiler chickens fed CF supplemented with 2% VM (T2) were recorded with the highest values of final body weight and weight gain compared to T1 group and T4 group, respectively. However, broiler in T2 group had similar values of body weights and weight gains compared to T3. Consequently, 2% level of VM had an optimum result in final weight, weight gain, and feed consumption, while comparable to the other treatments in water consumption, feed conversion ratio, dressing percentage, and carcass weight. Cost and return analysis of the dietary treatments with VM showed a negative effect, since the higher concentration of VM supplementation had the higher cost in production, due to the expensive price of imported vermin or earthworm meal.   Keywords: broiler chickens, performance, total confinement, vermi meal

 This experiment was conducted to determine the effect of dietary utilization of baobab leaf meal (BLM) on performance, carcass characteristics and hematological parameters of broiler chickens. Two hundred and twenty-five (225), one day old broiler chickens (Marshall Breed) were used for the study. Five diets were formulated containing baobab leaf meal (BLM) at dietary levels of 0, 2.5, 5, 7.5 and 10% designated as T1, T2, T3, T4 and T5 respectively. Chicks were randomly allotted to treatments in a completely randomized design (CRD) and each treatment was replicated three times consisting of 45 broiler chickens with 15 chicks per replication. The experiment lasted for eight weeks. Sample of BLM, experimental diet and faeces were analyzed for proximate compositions. Similarly, levels of anti-nutritional factors in BLM were also evaluated. The results at starter phase showed that the final body weight, daily weight gain and total weight gain were significantly (P < 0.05) higher at 7.5% BLM diet compared to other treatments. The feed conversion ratio (3.30) and feed cost in naira per Kg gain (N257) were significantly (P< 0.05) better at 7.5% BLM diet compared to others. The same trend was observed at finisher phase in the final body weight (2147.80g) and daily weight gain (52.39g). Similarly, feed conversion ratio (3.14) and feed cost in naira per Kg gain (N289.89) were significantly (P< 0.05) better at 7.5% BLM diet compared to other treatments. The results for carcass analysis showed that there were significant differences (P < 0.05) in final live weight (2.15 Kg) as broiler chickens fed 7.5% BLM diet had significantly (P< 0.05) highest values of carcass weight (1.52 Kg) and dressing percentage (72.04%). There were significant differences (P<0.05) in thigh muscle, back and small intestinal weights in which 7.5% BLM diet had the highest values across the treatments. Most of the organs weights were not significantly (P>0.05) affected by BLM inclusion with exception of crop and proventriculus. Therefore, it was concluded that BLM can be incorporated in the diet of broiler chickens up to 7.5% level without any adverse effect on the performance, carcass yield with concomitant reduction in the cost of production

Maize,which suppliesmost of the energy in poultry feeds, has low yields inNigeria and there is competition for the limited harvest of maize between industrial, livestock and human needs. Thus, this study was carried out to evaluate the effects on the growth and carcass characteristics of broiler chickens of replacing the high inputs grain,maize,with a low inputs grain, 'acha', or medium inputs grains, sorghum and millet. Four isocaloric and isonitrogenous diets for both the starter and finisher phases were formulated with maize, sorghum, millet and 'acha' as the main source of energy and were used as treatments 1, 2, 3 and 4, respectively.Marshall broiler birds were brooded up to 2 weeks before the treatments were introduced that lasted six weeks.Up to 8 weeks of age, body weight, average daily gain, feed conversion ratio and mortality were recorded weekly. The results of the study show no significant differences (P>0.05) between the four treatments in final body weight and average daily gain but birds on treatment 4 ('acha') had significantly lower feed intake and superior feed conversion ratio than the other experimental diets. Itwas concluded thatmaize can be replaced with sorghum, millet and 'acha' without adverse effects on the performance of broiler chickens.

We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures −80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

Two experiments were conducted to study the effects of either soluble or insoluble fibre naturally occurring in wheat and oats, on technical pellet quality and nutritional value for broiler chickens. In exp. 1, the effects of insoluble fibre were studied by mixing diets based on wheat or naked oats with either coarse or fine oats hulls followed by pelleting. Hull inclusion increased (P < 0.05) starch gelatinisation, especially in the diets based on oats. Addition of finely ground oats hulls improved pellet durability, in particular after storage, while no such effect was observed for coarse oats hulls. Oats hulls inclusion caused a more elastic pellet with higher breaking resistance (P < 0.05). Lower (P < 0.05) energy consumption was observed for diets based on oats compared with wheat, while no effect of fibre inclusion on energy consumption was found. In exp. 2, the influence of pelleting on the viscosity effect of soluble fibres in diets based on wheat or oats was studied. A significant increase (P < 0.05) in intestinal viscosity of broiler chickens was observed for all batches of grain exposed to steam pelleting. Viscosity was doubled (P < 0.05) with wheat diets, while the increase in viscosity was even greater in oat diets. In wheat diets, feed intake and weight gain was reduced (P < 0.05), while feed conversion ratio was not affected. Steam pelleting of oats reduced (P < 0.05) feed intake and weight gain, and increased feed conversion ratio (P < 0.05). The improvements (P < 0.05) in metabolisable energy and dry matter digestibility in wheat diets was not consistent with the observed increases in viscosity or with the results obtained with oats. Key words: Soluble fibres, insoluble fibres, viscosity, starch gelatinisation, steam-pelleting

The present study was conducted to determine the effect of silicon oxide in broiler chickens drinking water on performance and litter quality. A total of 120, one-day old mixed sex broiler chicks were randomly divided into 4 treatments and 3 replications, with 10 birds in each replicate in a completely randomised experimental design, with 4 silicon levels (0.00, 1.50, 2.00 and 2.50 mg of silicon oxide/litre of water. Corn-soya based diets were formulated at the starter (0–4 weeks) and finisher (5–8weeks) phases and were supplied ad libitum with free access to water. The average daily temperature and relative humidity inside the poultry house were 35.9 °C and 36%, respectively. At the starter phase, chicks administered 2.00mg silicon oxide/litre of water had significantly (p<0.05) higher final body weight (991.00g) and average weight gain (950.96g) compared to chicks without silicon oxide 778.57 g and 738.54g. The inclusion of 2.00 mg silicon oxide/litre of water improved feed conversion ratio compared to the control group (p < 0.05) and significantly reduced feed cost per kg gain. For the finisher phase, chickens administered 2.00mg silicon oxide/litre of water had the best results for final weight, weight gain and feed cost per kg gain. Also, inclusion of silicon oxide in broiler chickens water improved litter quality as predominantly dry material but with some areas of wet shavings was observed. In conclusion, silicon oxide in broiler chickens drinking water at 2.00mg/litre of water enhanced growth performance, improved feed conversion ratio and litter quality as well as reduced feed cost per kg gain at the starter and finisher phases respectively.
