Context Dilution of commercial feed with moderate levels of copra meal (CM), a byproduct of coconut oil extraction, was shown to maintain broiler performance in older breeds, but reports on its use in modern fast-growing broilers are limited. Aims We evaluated feed dilution with CM and enzyme supplementation in broiler chickens. We hypothesised that (i) diluting commercial feed with CM will maintain performance of modern fast-growing broilers, and (ii) enzyme supplementation will improve utilisation of the diluted diets. Methods Experiment 1 studied the performance of growing broilers (10–21 days of age) fed commercial grower diet alone (control), or diluted with one of two levels of CM (50 and 100 g/kg) and with or without enzyme supplementation. Cobb 500 broiler chicks (10 days old), 200 in total, were assigned to five dietary treatments with four replicates, in a completely randomised design. Experiment 2 investigated higher levels of dilution (100 and 200 g CM/kg) and enzyme supplementation of commercial finisher diet in 200 finishing broilers (22–42 days of age) assigned to five treatments with four replicates each. Key results In Experiment 1, feed intake was reduced (P < 0.05) on the 100 g CM/kg diet without enzyme compared with 50 g CM/kg without enzyme and both of the enzyme-supplemented diets but was not different (P > 0.05) from the control. Bodyweight gain and feed conversion ratio were not affected (P > 0.05) by dietary treatment. In Experiment 2, feed intake was reduced on 200 g CM/kg with enzyme but did not differ (P > 0.05) among the control and other CM-based diets. Bodyweight gain (P < 0.05) was reduced on the 200 g CM/kg diet without enzyme compared with the 100 g CM/kg diet without enzyme. Feed:gain was not affected (P > 0.05) by diet. The relative weight of carcass and cuts, gut segments and annex organs was not affected (P > 0.05) by diet. Conclusions Diluting commercial grower and finisher diets with 50 and 100 g CM/kg has no adverse effects on performance of modern broilers. At higher levels of dilution (100 and 200 g/kg), enzyme supplementation may be required. Implications These findings will reduce the cost of broiler production and add value to CM in coconut-producing regions. We recommend more research into higher rates of dilution, sources of CM, and enzyme sources and levels that might improve performance and reduce cost of production.

The effects of wet feeding and a multi-enzyme preparation on the nutritional value of wheat screenings (WS) for broiler chicks were investigated. In total, 540 1-day-old Ross-308 broiler chicks were fed a corn–soybean meal-based diet up to 29 days of age. At that time, the birds were randomly assigned to nine diets in a completely randomised design with a 3 × 3 factorial arrangement, including three levels of WS (0%, 25% and 50%, WS0, WS25 and WS50 respectively) and three processing methods (no processing, enzyme supplementation and wet feeding). The enzyme mixture contained endo-1, 4-β-xylanase (200 FXU/g), endo-1, 4-β-glucanase (50 FBG/g), endo-1, 8-β-glucanase (21 FBG/g), hemicellulase (3000 VHCU/g), α-galactosidase (3 GALU/g) and protease (260 U/g) and was supplemented at a level of 6 g/kg of diet. The inclusion of water in wet diets was in the extent of 1.2 kg/kg of diet. During the period from 29 to 49 days of age, feed intake was not affected (P > 0.05) by the inclusion of WS in the diet, whereas chicks fed the WS25 diet had a higher (P < 0.05) bodyweight gain than did those on WS0 diet. The feed conversion ratio (FCR) was improved (P < 0.05) by the inclusion of WS in the diet throughout the study. The feed intake was increased (P < 0.05) by enzyme supplementation to WS50 diet, while bodyweight gain was increased (P < 0.05) by wet feeding. Enzyme supplementation did not affect (P > 0.05) FCR, whereas wet feeding resulted in lower (P < 0.05) FCR over the entire study. The plasma concentration of glucose was increased (P < 0.05) by the inclusion of WS in the diet. The viscosity of the ileal digesta was higher (P < 0.05) in chicks receiving the WS50 diet than that in chicks receiving the other diets. The jejunal villus height was increased (P < 0.05) and the jejunal crypt depth was decreased (P < 0.05) by the inclusion of WS in diet. The jejunal crypt depth was greater (P < 0.05) in chicks receiving the wet diets than in chicks receiving the enzyme-supplemented diets (P > 0.05). In conclusion, the results from the present study indicated that broiler growth performance was improved by the inclusion of WS in the diet and also by wet feeding. These effects were largely compatible with the changes that occurred in the small intestine morphology, but not with those observed for ileal digesta viscosity.

This experiment was conducted to investigate the effect of rosemary powder in diet on blood metabolite and performance of broiler chickens. 180 one day broiler chicks were distributed in a completely randomize design with 4 treatments and 3 replicates and 15 bird in each. Experimental treatments were included: Control (without additive), 0.05, 0.1 and 0.2 percent of rosemary in diet. In 42 day of age one bird from each replicate was selected and slaughtering for carcass traits. The results were sowed use of 0.05 percent of rosemary could be significantly increased feed intake of broiler in starter period (p<0.05). Also use of 0.1 percent of rosemary caused to significantly increase broiler body weight gain in overall of rearing period than 0.2 percent group (p<0.05). Use of 0.1 percent rosemary in diet had a significantly  feed conversion ratio (FCR) than T4 (0.2% rosemary). Experimental treatments had no significant effect on carcass traits, except in liver percent weight, which had significantly higher in T2 group (p<0.05). Also experimental treatments had no significant effect on glucose, cholesterol, triglyceride level of broiler chickens in 42 day of age. The results of this experiment showed use of rosemary powder could be improved broiler feed intake in starter period.

The present study was carried out for six weeks to investigate the effects of adding graded levels (0, 0.1 and 0.5%) of garlic (Allium sativum) powder to the basal experimental diet on the growth performance and carcass characteristics of broiler chicks. One hundred and eighty (n = 180) day old unsexed white commercial broiler chicks (Cobb-400) were randomly distributed into three dietary treatments of 60 birds/treatment and each treatment contained 4 replicates (15 birds/replicate). The dietary treatments were controlled basal diet (T1), and a diet supplemented with garlic powder at 0.1% (T2) and 0.5% (T3). Daily feed intake, weekly body weight, and residue leftover were recorded to calculate the feed conversion ratio (FCR). At the end of the experiment, six birds from each group were sacrificed to determine the carcass characteristics. Results revealed that dietary supplementation of 0.1% garlic powder (T2) significantly (p less than 0.01) improved body weight, body weight gain, feed intake and FCR as compared to birds supplemented with 0.5% garlic powder (T3) and control diet (T1). Dietary supplementation of 0.1% garlic (T2) resulted in significant (p less than 0.05) improvement in dressed yield as comparedto T3 and T1. On the other hand, comparable (p greator than 0.05) effect was observed on shrinkage loss, blood loss, feather loss, eviscerated yieldand relative weight of giblet. Thus, dietary supplementation of 0.1% garlic powder had beneficial effects on growth performance and dressed yield of broiler chicks.

The effects of processing by mashing, cold-pelleting, bent- pelleting and extrusion, and enzyme applicatentation of diets containing 0200 and 400g cassava root meal (CRM)/kg on the performance of broiler chicks were studied. During the first week, DM intake was higher (P<0.05) for the chicks on Diet 1 and the absence of CRM while feeding mash as against pellets reduced feed intake from 7- 28d (P<0.05), weight gain (P<0.001) and feed to gain ratio (P<0.001). Heat -pelleted and extruded diets did not result in significantly, higher intakes (P>0.05) and weight gains compared with the cold-pellet diets. Supplementation with Enzyme premix improved feed to pain ratio (P<0.05) during the resistant starch at first week but had no effect over the 3 week period of the study. Ideal viscosity tests showed In Europe, dietary CRM inclusion had a significant effect (P<0.001) on the intestinal viscosity.

The experiment was carried out to determine the overall performance and economic analysis of broiler chickens fed different commercial diets marketed in Kano metropolis. A total of 112 day-old Zertek strain of broiler chicks were randomly allotted to four dietary treatments coded as A, B, C and Din a completely randomized design. Each group was replicated 4 times with seven birds per replicate. Birds were weighed at the onset of the experiment and weekly thereafter. Feed intake and live weight gain were measured, recorded and used to determine the feed conversion ratio. The chicks were managed on a deep litter system and the experiment lasted for six weeks. Feed and water were supplied ad libitum throughout the feeding trial. Results revealed that feed intake of birds ranged from 78.5-87.3 (g/b/d), live weight gain ranged from 49.3 – 53.9 (g/b/d) while feed conversion ratio ranged between 1.59 and 1.64. There were no significant (P > 0.05) differences in feed intake and feed conversion ratio. However, significant (P < 0.05) difference was observed in live weight gain where birds on treatments B, C, and D were superior to birds on treatment A. The market costs of the feeds at the time of the experiment were used to calculate the feed cost (₦ / kg), total feed cost (₦), feed cost (₦ /kg gain). Feed cost ₦/kg gain was best in treatment A.

In total, 392 male broilers were randomly distributed in a factorial arrangement of 2 × 4, with two commercial broiler strains (Arbor Acres (AA) and Hubbard (Hub)) and four (NRC, Degussa, CVB, and strain guides) different feeding regimens (FR), totaling eight treatments and seven replicates, with seven broilers in each one. The following parameters were evaluated: bodyweight gain (BWG), feed intake (FI), feed conversion ratio (FCR), carcass yield, meat quality, nutrient intake, and its correlation with BWG. Interaction strain type × FR was significant for BWG, FI, and FCR, with the AA broilers showing higher BWG and FI and lower FCR than the Hub broilers. There was no difference in BWG, FI, and FCR of the AA broilers regardless of FR they were on, but the Hub broilers had lower BWG when they were fed according to the Degussa and CVB regimens; BWG and FCR were negatively affected. During the starter phase, BWG of the AA broilers was significantly correlated with feed, metabolisable energy (ME), lysine, and sulfur amino acids (SAA) intake. However, BWG was correlated with feed and ME intake and feed intake from 1 to 31 and from 1 to 42 days of age, respectively. In the Hub chicks, ME and crude protein intake and lysine and SAA intake were inversely correlated with BWG from 1 to 31 days and from 1 to 42 days of age, respectively. There was no significant effect of FR on dressed carcass weight or relative gizzard, pancreas, and liver weights and on intestinal weight; however, abdominal fat and spleen differed significantly with FR. Strain type significantly affected the relative weight of the intestines. There was no significant effect of FR and/or strain type on meat moisture, crude protein, lipid and ash content, or pH, colour, meat juiciness and tenderness (meat softness). In conclusion, AA strain of broiler performed better than the Hub strain under the different FR in all the evaluated production phases, but neither FR nor strain type affected carcass characteristics.

The effect of different enzyme products on the utilisation of high copra meal (CPM)-based diets by growing pigs was investigated in two experiments (1 and 2). Four diets containing 0, 150, 300 and 450 g CPM/kg were fed in Experiment 1. Feed intake and bodyweight gain were depressed (P < 0.05) above 150 g/kg inclusion but final bodyweight was maintained (P > 0.05) up to 300 g/kg dietary CPM. Dressing percentage improved (P < 0.05) on 150 compared with the control and 450 g/kg diets. In Experiment 2, four diets based on 300 g CPM/kg unsupplemented/supplemented with Allzyme, β-mannanase or their combinations were fed. Feed intake reduced on the control compared with Allzyme supplementation (P < 0.05). Bodyweight gain was improved with Allzyme supplementation. Pigs fed diets supplemented with Allzyme and mannanase converted their feed into weight better (P < 0.05). Growth rates decreased when CPM was included in the diet at levels greater than 150 g/kg, but at 300 g/kg the decrease in growth rate was much less when supplemented with Allzyme or β-mannanase.

Feeding Diets

High inclusion concentrations of dietary calcium (Ca) from limestone may have detrimental effects on broiler performance, such as increased gastric pH and a reduction in phosphorus (P) and amino acid digestibility. To assess the potential for feeding diets with lower total Ca concentrations, the effect of a novel highly soluble source of calcium (HSC) on bird performance, nutrient digestibility and skeletal integrity of 1120 male Cobb-500 broilers was compared with that of limestone. Eight dietary treatments in a 2 × 2 × 2 factorial design consisted of two sources of Ca (limestone or HSC), two concentrations of Ca (6.0 or 7.7 g/kg in the starter and 4.0 or 5.7 g/kg in the grower), two phytase levels (0 or 500 FTU/kg). The effect of dietary treatments on growth performance and feed intake were measured from Day 1 to Day 40 and foot ash and leg health on Day 40. At the end of the starter period, in the absence of phytase, changing Ca source from limestone to HSC at 6.0 g/kg total Ca decreased both bodyweight gain and feed intake (P < 0.05). The addition of phytase to diets containing 6.0 g/kg total Ca provided by HSC increased bodyweight gain (P < 0.05), as well as increasing feed intake (P < 0.05). At the end of the grower period, diets supplemented with phytase increased bodyweight gain (P < 0.001), birds fed the higher Ca concentration were also observed to have an increased bodyweight gain (P < 0.001). Apparent ileal Ca digestibility significantly increased with the addition of phytase to diets containing 4.0 g/kg total Ca provided by HSC (P < 0.05), this was also observed for P digestibility. Replacement of limestone with HSC when fed in conjunction with phytase has the potential to be an effective strategy to improve broiler performance and bone mineralisation.
