The study was conducted to investigate the productivity and profitability of broiler on L-methionine supplemented diet. A total of 160 day-old broiler chicks (Cobb 500) was randomly distributed to four dietary supplements, D0 (Control), D1 (0.30 % L-Met), D2 (0.35 % L- Met) and D3 (0.40 % L- Met). Each treatment was replicated five times with 8 birds per cage. The chicks were reared in the battery cages while they were fed with broiler starter diet (crumble) until Day14 of age. The birds with fed with L-Met supplemented diets starting from Day15 until Day35 of age All the diets were iso-caloric and iso-nitrogenous.. Results revealed that the L-Met supplementations were in favor of higher live weight (LW) and better (p<0.05) feed conversion ratio without affecting the feed intake (FI). The D3 diet resulted higher (p<0.01) LW in the birds than all others on Day35 of age. The livability (%) was unaffected (p>0.05) by the dietary supplements. No significant (p>0.05) difference was observed in the relative weights of visceral organs (small intestine, proventriculus, gizzard, liver and heart) except for the spleen. Relatively increased (p<0.05) spleen weight (%) was observed in the D3 diet. The breast weight (%) was increased marginally (p<0.07) in the D3 group, while the other carcass parts; breast weight, thigh weight, wing weight, shank weight, drumstick weight, neck weight, and abdominal fat content were found to be similar (p>0.05) in the dietary groups. Higher profit (p<0.01) and lower production cost (p<0.05) were observed in the D3 group than that of the others. It can be inferred that 0.40% L-Met supplementation in the broiler diet is better for growth performance and profitability. Bang. J. Livs. Res. Vol. 27 (1&2), 2020: P. 1-14

A total of two-hundred-and-forty day old broiler chicks were used to study the response of broiler birds to diets containing graded levels of tiger nut residue (TNR) as a replacement for maize. The diets consisted of 0, 10, 20 and 30% of TNR as a replacement for maize as T1 (control), T2, T3 and T4 respectively. The birds were allotted to four dietary treatments of 4 replicates each containing 60 and 15 birds respectively in a completely randomized design. The data obtained from the experiment were subjected to one - way analysis of variance. The results showed that average weight gain (AWG) and final weight gain (FWG) were high for birds fed 10% TNR and increased numerically than the 0, 20 and 30% groups at the starter phase. In the finisher phase the average weight gain (AWG) and final weight gain (FWG) followed the same trend. Feed intake was not significantly affected by the diet at the starter and finisher phases. In the starter phase the T1 (control) recorded the best and the lowest feed conversion ratio but in the finisher phase, the best feed conversion ratio was observed in T2. The TNR inclusion had no significant (p˃0.05) effect on live weight, dressed weight, dressing percentage, cut-parts and organs of the birds. The haematological parameters were not significantly (p˃0.05) affected by the diets. All the biochemical parameters determined; serum protein, albumin, globulin, urea, creatinine, ALT, AST, cholesterol and triglyceride were not significantly (p˃0.05) affected by the treatment diet. It was concluded that tiger nut residue (TNR) as a replacement for maize at a 30% level of inclusion did not cause any deleterious effects on the performance, carcass and blood profiles of broilers

This study was carried out to determine the effects of in ovo pollen extract injection on growth parameters, ileal histomorphology, and caecal microflora of fasted broiler chicks. In this experiment, 2×2 factorial experimental design was used. One d old, 120 healthy broiler chicks were allocated to 4 treatment groups and 6 replicates (5 mixed sex chicks allocated each replicates). Treatment groups were: A) Pollen extract injection and 24 h fasting (P24); B) Pollen extract injection and 48 h fasting (P48), C) Control, no injection 24 h fasting (C24) and D) Control, no injection 48 h fasting (C48). The experiment lasted 21 days. Live weight, feed consumption, feed conversion ratio were recorded weekly. Ileal histomorphology, caecal microbiota, organ weight were recorded at 21th days of experiment. In ovo pollen extract injection did not affect hatchability rate. At the end of 21 days, in ovo pollen extract injection did not affect feed intake, live weight gain, feed conversion ratio, inner organ development and ileal villi width irrespective to fasting 24 h and 48 h. In ovo pollen extract injection increased ileal villi length, caecal lactic acid bacteria and Saccharomyces Cerevisiae count, decreased caecal Enterobactericaea count. In conclusion, in ovo pollen extract injection can be applied for broiler eggs to improve weight gain, better digestion and gut health.

The objective of the study was to evaluate the effect of two methods of processing Bambara Groundnut Offal (BGO), toasted and enzyme supplemented in broiler chicken diets on haematology and carcass characteristics of broiler finisher chicken. One hundred and eight (108) four- weeks- old unsexed commercial broiler chicks were divided into three groups (T10% T220% T320%) of 36 birds, each replicated three times with 12 birds per replicate in a completely randomized design and fed for 28 days. Haematological parameters were not significantly (p>0.05) affected. Result of carcass characteristics showed that live weight, eviscerated weight, dressed weight, back weight, drumstick weight, breast weight, thigh weight and caecum weight were significantly (p<0.05) affected. Birds fed enzyme supplemented BGO diets recorded higher weights compared with birds fed toasted BGO and the control diets. Other carcass  characteristics such as wing weight, neck weight, head weight,  shank weight and other internal organ characteristics were not significantly (p>0.05) affected. From the result, significant parameters have shown that birds fed bioenzyme supplemented BGO diets were superior to birds fed toasted BGO and the control diet. It is therefore recommended that 2g/kg bioenzyme supplemented BGO diet should be used at 20% BGO inclusion rate for finishing broiler chicken without adverse effect on the haematology and for increased carcass weight.

Materi yang digunakan yaitu 200 ekor ayam broiler jantan umur 2 hari, ransum mengandung gulma obat dan kulit nanas yang difermentasi dengan yogurt. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 5 ulangan. Perlakuan yang diberikan yaitu T0 (ransum kontrol, ransum mengandung 0 % KNF dan 0 % GO), T1 (ransum mengandung 0 % KNF dan 2 % GO), T2 (ransum mengandung 7,5 % KNF dan 2 % GO), T3 (ransum mengandung 15 % KNF dan 2 % GO), dan T4 (ransum mengandung 22,5 % KNF dan 2 % GO). Peubah yang diamati adalah konsumsi ransum, pertambahan bobot badan (PBB), bobot akhir dan konversi ransum. Data dianalisis menggunakan ANOVA dan Uji kontras ortogonal. Hasil penelitian menunjukkan bahwa pemberian ransum yang mengandung KNF berpengaruh nyata (P<0.05) terhadap konsumsi ransum, PBB, bobot akhir, dan konversi ransum. Konsumsi dan konversi ransum meningkat dengan peningkatan pemberian KNF sedangkan bobot badan menurun. Disimpulkan bahwa pemberian tepung kulit nanas setelah difermentasi dengan yogurt sebanyak 22,5 % di dalam ransum mengandung campuran gulma obat dapat menurunkan performa ayam broiler. (Broiler chicken performance fed fermented pineapple peel by yogurt in diet containing medicinal weed)ABSTRACT. Research aimed to determine broiler performance fed different level of yoghurt - fermented pineapple peel (FPPM) in the diet containing medicinal weed. Two hundred 2 day - old male broiler chicken, diet containing medicinal weed  (MW) and yoghurt - fermented pineapple peel used in this study. The experimental design was a completely randomized design with 5 treatments and 5 replications. The treatments were T0 (control, diet containing 0% FPPM and 0% MW), T1 (diet containing 0% FPPM and 2% MW), T2 (diet containing 7.5% FPPM and 2% MW), T3 (diet containing 15% FPPM and 2% MW), and T4 (diet containing 22.5% FPPM and 2% MW). The variables were feed consumption, body weight gain, live weight and feed conversion ratio. Data were analyzed by ANOVA and Contrast orthogonal Test. The results showed that there was a significant effect (P<0,05) of treatment on the feed consumption, body weight gain, live weight and feed conversion ratio. Feed consumption and feed conversion ratio increased with increasing level of FPPM in the diet, however, body weight decreased. It is concluded that feeding yoghurt - fermented pineapple peels up to 22,5 % in the broiler diet containing medicinal weed decreased broiler chicken performance.

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.

The differences in the performance, carcass parts, and internal organs of broiler chicken females and males fed ad libitum or restricted by 80 and 65% ad libitum were evaluated. Ross 308 males and females (2430 chickens) were fed ad libitum (ADL) or were restricted in days 8–14 of age by 80% ADL (R1) and 65% ADL (R2), respectively. Feed restriction depressed the live weight (P ≤ 0.001) in both sexes. Both sexes compensated for growth, and at the end of the fattening at 35 days, the restricted males (–3% R1 and –6% R2) and females (–3% R1 and –4% R2) were not significantly lighter than the ADL chickens. Feed intake was lower (P ≤ 0.001) in females than in males, and feed restriction and sex did not affect the feed conversion ratio. The growth of internal organs as early-developing tissues (heart, gizzard, liver) was less affected than the growth of late-developing tissues (breast, thigh, abdominal fat). Restricted males and females had more abdominal fat than the ad libitum chickens (P ≤ 0.05). Differences in allometric growth between males and females were in the liver, breast, and thigh. At the end of the experiment, restricted males had a higher weight of breast and thigh, whereas in females, the weights of both parts were similar to those of the ADL group. During the restriction period, the growth of internal organs is given priority compared to muscles, which was confirmed by allometric growth. Males showed a higher compensatory growth, including the growth of breasts and thighs.

This study was conducted with Thai broiler chicken (KKU 1) to investigate the effect of citric acid by-products from rice (CABR) on growth performance and villi histology. A total of 192 broiler chicks were subject to three dietary treatments, including 0% CABR, 3% and 6% of dry matter. Body weight gains, feed intake, feed conversion ratio, survival rate, and production index (body weight gain, feed intake, feed conversion ratio, survival rates, and productive index, respectively) were considered for growth performance evaluation. Villi height (µm), crypt depth (µm), and villi: crypt ratio were recorded for the villi histological measurement. The performance did not show a significant effect when compared with the control group during at ages ranging from 1 to 56 days. Villi histology indicate a significant effect on villi height (µm), crypt depth (µm), and villi: crypt of broiler chicks compared with the control group. Also, the use of 3% CABR caused a reduction microbial contamination in chicken fecal matter. In conclusion, supplementation of CABR had no negative effects on growth performance of Thai broiler chicken (KKU 1). Also, the addition of 3% CABR to the feed might help reduce fecal microbial contamination and affect the villi histology of Thai broiler chickens (KKU 1).

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

Pre-natal (PN) and post-hatch (PH) assessments were carried out on two broiler chicken strains to examine possible origin of strain differences and response to heat stress. One hundred and forty fertile eggs incubated for 18 days as PN and 192 day-old broiler chicks as PH; were evenly divided between two strains (Arbor Acres [AA] and Marshal [MS]). For the PN assessment (day 18, 19 and 21 of incubation), embryos were dissected and organs weighed. Liver glycogen and moisture content of the carcass and residual yolk sac were also determined. Post hatch, average body weight (ABW), average daily feed intake (ADFI) and feed conversion ratio (FCR) were measured under high natural ambient temperatures. At d 18 of incubation, proportional breast weight and yolk moisture was higher in AA than MS (P < 0.05), with the same trend observed at d 21 for yolk weight (%). Breast, gizzard, heart and liver weights were observed to increase linearly, in proportion to weight of embryo (P <0.001), between d 18 and 21 on incubation, while the inverse was observed for yolk weight (%). Post-hatch, ADFI and FCR at the end of the starter phase were lower in MS compared with AA (P < 0.05). However, at the end of the finisher phase, only ADFI was significantly influenced by strain of broiler (AA < MS; P < 0.05). Serum electrolytes and carcass characteristics did not differ between strains (P > 0.05). Phenotype differences in were manifested prior to hatch, with Marshall exhibiting advantage to Arbor Acres under high ambient temperatures.

The aim of this study was to determine the effects of in ovo injection of Saccharomyces cerevisiae (SC) to fertile Ross 308 broiler eggs or dietary supplementation on growth performance, internal organ development, gut histomorphology and cecum microbiota during 14 d of growing period. This study was designed as 2×2 factorial experimental design. Fertile 92 Ross 308 eggs were injected with SC solution 0.2ml at 18d of hatch and 90 eggs non-injected as control, afterward dietary SC supplementation was applied during the 14 d to broiler diet. In this study, 160 broiler chicks were used in four treatment groups at 10 replicate for each treatment group and 4 chicks for each replicates. Treatment groups were A) in ovo SC injection + dietary SC supplementation, B) in ovo SC injection + basal diet, C) no injection + dietary SC supplementation, D) no injection + basal diet as control. Live weight, feed consumption, feed conversion ratio and gut histomorphology, caecum microbiota, internal organ weight were recorded at 14 days of age. Live weight gain increased in C group than in the D group. Feed consumption, feed conversion ratio and internal organ weights were not affected by the treatments. Villi length and villi width increased in A group among the other treatment groups in jejunum, villi length increased in A and C groups among the other groups in ileum. Villi length/villi width ratio increased in A group than in the D group in ileum, was not different in jejunum. LAB counts in caecum were higher in A group than those of C and D groups, but was not different from B group. Enterobactericaea count was lower in A and B group than in the D group, was not different from C group. To conclude, results showed that dietary Saccharomyces cerevisiae supplementation increased broiler growth at 14 day by increasing villi development and improving gut health.
