An experiment was conducted for a period of 5 weeks with 240 day-old cobb-500 broiler chicks and were allocated into six dietary treatments with isocaloric and isonitrogenous containing 2975 Kcal ME/kg DM & 21.70% CP and 3077 Kcal ME/kg DM & 20.34% CP both starter and finisher ration respectively. There were 40 chicks per treatment, each treatment had 4 replication having 10 chicks in each. The dietary treatments were T1 (0% triticale + 100% maize), T2 (20% triticale + 80% maize), T3 (40% triticale + 60% maize), T4 (60% triticale + 40% maize), T5 (80% triticale + 20% maize) and T6 (100% triticale + 0% maize). The broilers of all treatment groups were supplied feeds and water ad libitum throughout the experimental period. There were no significant differences (P>0.05) in feed intake, final body weight, total gain, feed conversion efficiency, survivability% but feed cost per kg live broiler production was differed significantly (P<0.01) among dietary treatments at 35 days of age. Therefore, it is clear that triticale is a good alternative cereal for broiler diet without affecting performance and it may safely replace up to 100% of maize but 40% replacement enhance production performance and edible meat yield of broiler and reducing feed cost (Tk. 2.88/kg) per unit of broiler production.Keywords: Triticale; maize replacement; production performance; meat yield characteristicsDOI: http://dx.doi.org/10.3329/ijns.v1i1.8613 International Journal of Natural Sciences (2011), 1(1):25-30

Abstract The effects of feeding diets based on soybean meal, low phytate hulless barley (Lphybarley) and low phytate pea (Lphypea) with inorganic phosphorus (iP) reduced by 50 or 100% to broiler chickens on performance, P digestibility and bone characteristics were investigated. Two hundred and ten day-old (Ross 308 strain) broiler chicks (5 birds per cage; 6 cages per diet) were randomly allocated to 7 dietary treatments for a 21-day study. Diets were formulated based on soybean meal-normal phytate hulless barley (SBM-normbarley) with added inorganic P (iP) to meet NRC (1994) P requirements (SBM-normbarley100) or with 50% less iP (SBM-normbarley50), soybean meal-Lphybarley-Lphypea with added iP (Lphybarley-Lphypea100) or iP reduced by 50% (Lphybarley-Lphypea50) or 100% (Lphybarley-Lphypea0), and soybean meal-normbarleynormal phytate pea (normpea) with added iP (normbarley-normpea100) or iP reduced by 50% (normbarley-normpea50). Birds fed the Lphybarley-Lphypea0 diet had the lowest (P<0.001) ADG compared with those fed the other diets. Reducing iP by 50% led to a reduction (P<0.05) in ADG for birds fed the SBM-normbarley- and normbarley-normpea-based diets but not in the Lphybarley- Lphypea-based diet. Reducing iP by 50% led to a reduction (P<0.05) in ADFI in birds fed the SBM-normbarley-based diet and normbarley-normpea-based diet compared with those fed adequate iP. Feed conversion ratio was not affected by diet throughout the experimental period (P>0.10). Reducing iP content reduced P retention in the SBM-normbarley-based diet but not in the normbarley-normpea-based diet but tibia ash and length were reduced in birds fed both diets (P<0.05). Reducing dietary iP content linearly increased (P < 0.05) P retention and linearly decreased (P<0.05) tibia ash and length in the Lphypea-Lphybarley-based diets. In conclusion, feeding a low phytate hulless barley-low phytate pea based diet with iP reduced by 50% supported similar performance as control and increased P retention, suggesting that utilizing a combination of low phytate ingredients can reduce the need for supplemental iP with significant cost and environmental implication.

ABSTRAK. Recently, exploring unconventional feedstuffs were not merely interested at the point of lower cost, but also natural sources and supporting bird health have been noticing on the critical assessments by poultry nutritionists to serve well broiler meat. This study aimed to examine the effect of including fermented moringa leaf meal (fMOL) + yellow corn (yC) to substitute fractionally commercial diet (CD) on the performances and Income over Feed Cost (IOFC) of the broiler chickens. The study was done in the Field Laboratory of Animal Husbandry, Animal Husbandry Department, Syiah Kuala University from August 4 until September 15, 2020. The study used 100 broiler chicks strain CP 707, unsex. This study was set up into Block Randomized Design (BRD) consisting of 4 treatments and 5 blocks. The treatments were MC0 = 100% CD, MC1= 95% CD + 2,5% fMOL + 2,5% yC, MC2= 90% CDR + 5% fMOL + 5% yC, and MC3= 85% CD + 7,5% fMOL + 7,5% yC. The results of studies showed that including fMOL + yC to substitute partly commercial diet significantly (P0.05) reduced final body weight (FBW) and increased feed conversion ratio (FCR) of the broilers. Feed consumption statistically was not significantly affected but tended to reduce. Using fMOL + yC reduced feed cost but revenue and IOFC also declined. (Pengaruh penggunaan campuran daun kelor dan jagung terhadap performan dan IOFC ayam broiler) ABSTRACT. Tujuan penelitian ini adalah untuk melihat pengaruh penggunaan tepung daun kelor fermentasi (TKF) ditambah dengan jagung kuning (JK) sebagai pengganti sebagian ransum komersil (RK) terhadap performan ayam broiler. Penelitian ini dilakukan di Laboratorium Lapangan Peternakan, Fakultas Pertanian Universitas Syiah Kuala, Banda Aceh. Materi yang digunakan adalah 100 ekor DOC ayam broiler strain CP 707. Ransum perlakuan adalah MC0= RK 100%, MC1= 95% RK + 2,5% TKF + 2,5% JK, MC2= 90% RK + 5% TKF + 5% JK, dan MC3= 85% RK + 7,5% TKF + 7,5% JK. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) terdiri dari 4 perlakuan dan 5 kelompok. Pengelompokan didasarkan pada berat badan ayam pada awal minggu ketiga. Parameter yang diamati meliputi berat badan akhir, konsumsi dan konversi ransum, dan Income Over Feed and Cost (IOFC), Hasil penelitian memperlihatkan bahwa penggunaan TKF + JK sebagai substitusi sebagian ransum komersil nyata (P0,05) menurunkan berat badan akhir dan meningkatkan konversi ransum. Konsumsi ransum tidak nyata berpengaruh, namun cenderung menurun. Pengunaan daun kelor menurunkan biaya ransum, dan IOFC.

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.

This experiment was carried out to evaluate performance index and economic efficiency of broiler chicks fed diets containing dried blood rumen content mixtures (DBRCM) as a replacement for roasted soybean meal (RSBM). A total of 225 unsexed day-old broiler chicks (SASSO C44) were randomly allocated to five dietary treatments in a completely randomized design. Each treatment was replicated thrice with 15 birds per replicate. The experimental diets were formulated to contain 100% RSBM+0%DBRCM (T1), 80%RSBM+ 20% DBRCM (T2), 60% RSBM + 40% DBRCM (T3), 40% RSBM + 60% DBRCM(T4) and 20% RSBM+ 80% DBRCM (T5) based on a control ration contained 30% roasted soybean meal. The result showed that there was no statistical difference (P≥0.05) in performance index during the experimental period. The mean mortality was not influenced (P≥0.05) across the treatment groups. Birds fed T1 had the highest (P<0.05) and T5 the lowest (P<0.05) feed cost per kilogram feed. Feed cost per unit gain (Kg) was the highest (P<0.05) for T1 and the lowest (P<0.05) for T4 and T5. Total feed cost of the birds fed T1 was higher than those of the birds fed T5 diet. The highest (P<0.05) economic efficiency was observed for birds fed on T4 and T5. Based on this result, it could be concluded that 80% DBRCM can replace roasted soybean meal to achieve the highest economic efficiency, without affecting the performance index of broiler chicken.

A total of 200 Cobb 500 male broilers were randomly allocated to 4 treatments consisting of 5 replications with 10 chicks each in order to evaluate the effect of dietary garlic and thyme seed supplementation on the production performance, carcass yield and gut microbial population. Treatments were control diet (T1), control diet with 1% thyme seed powder (T2), control diet with 1% garlic powder (T3) and control diet with 0.5% thyme seed and 0.5% garlic powder (T4). Feed intake, body weight, weight gain, feed conversion ratio (FCR), carcass yield was not significantly (p>0.05) improved by dietary treatments compared to control. Escherichia coli (E. coli) count in the gut of broilers did not show significant difference among dietary treatments. However, Lactobacilli count in the gut of broilers significantly (p<0.05) increased in T2 compared to that of T1. Lactobacilli count in the gut of broilers received T1, T3 and T4 did not differ significantly (p>0.05) with each other. It was concluded that thyme seed was reliable as feed additive in the broiler diet and could provide positive advantages to the colonization and proliferation of Lactobacilli.

The The use of Kaolin as an inert ingredient in feed has been very common in the poultry industry. The present study aimed to investigate the effects of different inclusion rates of Egyptian kaolinite in broiler chickens’ diet on growth performance, immune response, some blood serum changes, and bone development. A total of 240 unsexed one-day-old Avian 48 breed chickens were used in this experiment. The chickens were individually weighed and randomly allotted into 3 equal groups (80 chickens per each group) and each group was subdivided into 4 replicates (20 chickens per replicate), which received one of the three experimental diets (0.0, 0.5, and 1.0% kaolin for groups 1, 2, and 3, respectively) during the experimental period (6 weeks). The obtained data revealed that kaolin addition at the dose of 0.5 or 1.0% in broiler chickens' diet insignificantly increased final body weight by 4.5% and 4.4%, respectively. On the other hand, it respectively decreased total feed intake by 1.0% and 1.8% and significantly improved the average feed conversion ratio and efficiency of energy utilization throughout the whole experimental period compared to the control. Moreover, kaolin addition had no adverse effect on the serum lipid profile and improved antioxidative activity through reduced nitric oxide and lipid peroxidase (malondialdehyde) concentrations or increased the activities of Glutathione peroxide, Catalase, and Superoxide dismutases in serum or liver tissues. Lysosomal and bactericidal activities were increased with kaolin addition at both levels in the broiler chickens’ diets. The present results suggested that the broiler chickens’ fed with kaolin-enriched diets improved growth, antioxidant activity, bone mineralization, and immune response.

This study was conducted in order to investigate the effects of a multivitamin complex and probiotic blend in drinking water before and after vaccination on growth performance, carcass traits, blood biochemical parameters and humoral immune response of broiler chickens. A total of 150 one day-old male broiler chicks (Ross 308) were randomly allocated to five treatment groups, with three replicates (10 birds per replicate) in a completely randomized design. Experimental treatments consisted of: 1) a basal diet and drinking water without any additives as control (C); 2) C + drinking water + multivitamin complex from 2 days before vaccination until 3 days after vaccination; 3) C + drinking water + multivitamin complex for 3 days after vaccination; 4) C + drinking water + probiotic blend from 2 days before vaccination until 3 days after vaccination; and 5) C + drinking water + probiotic blend for 3 days after vaccination. In the whole experimental period, feed intake, body and thigh weight and abdominal fat were significantly affected (P<0.05) by dietary treatments. On the contrary, no significant effect was observed on carcass characteristics, feed conversion ratio, blood parameters, antibody production against SRBC and IgG. The titer of IgM was higher in treatment (2) than other treatments at 28 d of age (P<0.05). In conclusion, a multivitamin complex supplied in drinking water for 2 days before vaccination till 3 days after vaccination is enable to improve broiler performance and immunity.

Production and slaughter traits of autosexing broiler combination reared either sex separate or mixed were investigated. A total of 180 day-old feather sexed broiler chicks were divided into three groups (n=60)- two sex separate (male and female) and one mixed (1:1), each with two replications of 30 birds. Body weight and feed intake were followed on a weekly basis; the average daily feed intake and feed conversion were calculated. By the end of the experiment (day 49), slaughter analysis was performed on 20 birds: 5 broilers from each of sex separate groups, 5 males and 5 females from the mixed group with live weight close to the group average. The carcass weight (g), weights of carcass cuts, giblets and abdominal fat were determined. Slaughter yield and body parts ratios were calculated. The results demonstrated that sex separate rearing of broilers contributed to higher final body weight - by 6.9 % in females (P<0.05) and by 2.9 % in males (P>0.05), but had no effect on feed conversion. Sex separate rearing resulted in heavier carcasses by 3.6% (P<0.05) and more uniform weight as compared to mixed rearing. The sex effect on body weight and slaughter traits was more considerable in males with respect to carcass, thigh, back, wings and giblets weights (P<0.05) but not abdominal fat whose weight was higher in female broilers (P<0.05). Better uniformity of final body weight of broilers reared sex separate and the reduced variation in carcass weight and weight of cuts (breast and thigh) would facilitate slaughterhouse processing and would contribute to the realization of produce and meeting distribution network demands

Phytase is essential for enhancing nutritional value of feed and improving animal growthperformance and health. A study was conducted to evaluate the influence of Smartchoicephytase enzyme supplementation in the diet of starter broiler chickens. A total of 150 Rossstrain broiler chicks were used for the study and allotted to five treatment groups of 30 birdseach. Each group was further divided into three replicates of 10 birds per replicate. Five isonitrogenous(21.40% CP) and iso-caloric (2975.40 kcal/kg ME) dietary treatments werecompounded to contain 0g/100kg (T ), 10g/100kg (T ), 15g/100kg (T ), 20g/100kg (T ) and 1 2 3 425g/100kg (T ) of a commercial Smartchoice phytase enzyme preparation for 28 days in a 5Completely Randomized Design (CRD). Feed and water were provided to the chicks adlibitum.Daily feed intake and weekly body weight were measured. The result showed that thedaily feed intake and daily protein intake were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation. Final live weight, daily weight gain and total weight gain weresignificantly different among treatments. Protein efficiency ratio were significantly (P<0.05)higher in T (2.10) than T (1.80) but similar to T (2.05), T (2.05) and T (1.96). Feed 1 5 2 3 4conversion ratio was significantly (P<0.05) different in T5 (2.58) and T (2.02) but similar 1(P>0.05) in T (2.02), T (2.28), T (2.31) and T (2.38). Mortality was lowest in T5. Total feed 1 2 3 4cost per bird and daily feed cost per bird were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation while cost per kg of feed and daily feed cost per bird were notsignificantly (P>0.05) affected. The findings from this study showed that Smartchoicephytase enzyme could be supplemented up to 20g per 100kg in the diet of starter broilerchickens.

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
