Seven hundred fifty day old unsexed broiler chicks were used in a 35-d trial to examine the effect of supplementing different levels of palm oil on lean meat yield of broilers. The chicks were randomly distributed following a completely randomized design in five treatment groups having three replications per treatment. Each treatment had 150 birds with 50 birds per replicate. Five diets were formulated using locally available ingredients as diet without oil, diet containing 2.0%, 3.0%, 4.0% and 5% palm oil. Results indicated that weight gain of broilers differed significantly (p<0.05) among the treatment groups at 2nd wk. The weight gain of 4% palm oil group was higher (p<0.05) than 5% dietary oil group at 2nd wk. At 5th wk, weight gain of without oil and 5% oil groups were similar (p>0.05). Feed intake significantly (p<0.05) differed at 2nd wk. Broiler that received 5% dietary palm oil group consumed the least amount of feed compared to others. No significant differences were found among the treatments in whole experimental period for feed conversion ratio. The meat yield characteristics did not differ (p>0.05) among the broilers receiving different levels of palm oil in diets except gizzard, wing meat and dark meat. Supplementation of oil resulted in significantly (p<0.05) increased dark meat weight at 3% level. Dressed yield of broilers had an increasing trend at increased level of palm oil supplementation up to 4%. However, at 5% supplementation dressed yield was lowest. Similar results were also observed in breast meat. Thigh meat was progressively increased for supplementation of oil up to 3% level, at higher level it tended to decrease.DOI: http://dx.doi.org/10.3329/bjas.v43i2.20705 Bang. J. Anim.

Six hundred day-old unsexed broiler chicks were used in a 42-day trial to compare the effects of different levels of palm oil supplementation on feed intake, weight gain, feed conversion and carcass quality of broilers. The chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. Each treatment had 150 broilers with 50 broilers per replicate. Four diets were formulated using locally available ingredients as diet without oil, diets containing 2.5%, 3.0% and 3.5% palm oil. All broilers had free access to ad libitum feeding. Results indicated that, supplementation of diets with different levels of palm oil significantly (p<0.05) influenced feed intake of broiler only at the age of 6th week. It was observed that as the level of supplementation increased, feed intake gradually decreased up to 6th week. Supplementation of diets with different levels of palm oil increased live weight gain of broilers. Differences (p<0.01) were observed at the end of 4th, 5th and 6th weeks of age only. Use of different levels of palm oil significantly (p<0.05) changed blood weight, heart weight and dressed weight. Survivability of broilers was higher in the supplemented group compared with without oil group. It was concluded that, supplementation of palm oil at 3.5% level in the diet of broilers resulted higher weight gain, better feed conversion and improved carcass characteristics comparing other levels. It may be concluded that supplementation of palm oil at 3.5% level in the diet of broilers resulted significantly (p>0.05) higher feed conversion ratio compared to 2.5% and 3.0% levels.DOI: http://dx.doi.org/10.3329/bjas.v43i1.19384 Bang.

Two experiments were conducted to study the effect of concentrated fish silage and additional fish fat on growth performance (exp. 1) and meat quality (exp. 2) of broiler chicks. In exp.1, 600 day-old male and female chicks with an initial weight of 36.3 g ± 0.6 SD were allocated to five treatment groups. The treatments were a control diet, two test diets with 50 g kg−1 fish silage and different levels of fish fat (6 or 8 g kg−1), and two diets with 100 g kg−1 fish silage and different levels of fish fat (8 or 10 g kg−1). In exp. 2, 150 day-old female chicks with an initial weight of 36.3 g ± 0.7 SD were allocated to five treatment groups. The treatments were a control diet, and one of four test diets containing 50 g kg−1 fish silage and different levels of fish fat (2, 9, 17 or 25 g kg−1). In exp. 1, chicks fed diets with fish silage had a greater weight gain (P < 0.001), a greater feed intake (P < 0.05) and a lower feed-to-gain (MJ ME kg−1) (P < 0.001) than those fed the control diet. In exp. 2, no significant differences in weight gain or carcass weight were found among diets. The proportions of the fatty acids C18:3, C20:1, C20:5, C22:5 and C22:6 in abdominal fat, and C20:1, C22:1, C22:5 and C22:6 in breast meat, increased by the dietary inclusion of fish silage and fish fat. Increasing levels of dietary fish fat decreased blood plasma levels of vitamin E and ceruloplasmin. The diets containing the highest levels of fish fat (16.8 or 24.8 g kg−1) caused off-odour and off-taste of thigh meat stored at −16 °C for both six months and one month.

An experiment was conducted with 3840 male Ross × Arbor Acres broiler chicks to test the effects of increasing dietary methionine and lysine on performance and breast meat yield. Supplemental methionine and lysine were fed in a 2 × 4 factorial arrangement in both starter (0–3 wk) and finisher (3–6 wk) diets. Methionine was fed at levels of NRC and 112% NRC. Lysine was fed at levels of NRC and 106% NRC, 112% NRC and 118% NRC. Increasing dietary methionine increased weight gain (P < 0.01), feed efficiency (P < 0.01) from 3 to 6 wk, and breast meat yield (P < 0.01) at 6 wk. Increasing dietary lysine caused a curvilinear response in breast meat yield (P < 0.05). Key words: Broiler, lysine, methionine, breast meat

Different Levels

This study aimed to evaluate the use of wattle tannin as an adsorbent of toxic metals in broilers fed on diets with different levels of replacement of limestone with golden mussel meal. First, we conducted a trial to evaluate the performance of broiler chicks from 1 to 21 days old when fed on wattle tannin. For this we used 720 male broiler chicks that were one day old, in a completely randomized design with six treatments and six replications. The treatments were composed of basal diets with increasing levels of wattle tannin (0, 250, 500, 750, 1000 and 1250 g tonne-1), where the tannin replaced the inert material of the feed. All of the diets were isonutritive and isocaloric. The results showed that 250 g tonne-1 of tannin was detrimental to weight gain, final weight and feed conversion, and the use of 1000 g tonne-1 of wattle tannin, in addition to these effects, caused a drop in consumption of the ration. There was no effect of treatment on morphometric measurements of villi, crypt or the villus:crypt ratio. Next, we conducted a second test to evaluate the performance of broiler chicks from 1 to 21 days of age when fed with increasing levels of replacement (0, 25, 50, 75, 100%) of limestone with golden mussel and even supplementation or not wattle tannin. Five repetitions were used and the birds were housed in a completely randomized design. In diets with the inclusion of tannin, 250 g tonne-1 of wattle tannin was used, which replaced the inert material in the feed. In this test, 1200 male broiler chicks that were one day old were used. The results showed that the golden mussel contains large quantities of calcium, with low concentrations of toxic metals and microbiological contamination within the allowed range. Performance data show that mussel can be used to replace up to 100% of limestone in feed without affecting the variables, but the use of 250 g tonne-1 of wattle tannin affects the performance of chicks. Bone quality was not changed by the treatments. Phosphorus and calcium in the bones remained stable during treatment and only the gray variation showed interaction effects from the use of mussel and wattle tannin.

Dietary Treatments

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.

The Impact

This study was carried out to evaluate the impact of raw and cooked wild cocoyam (Caladium bicolor) on the performance of broiler chicks. Wild cocoyam corms were divided into two batches. One batch was ground raw and the other batch was cooked before grinding. Wild cocoyam meals so prepared were used to formulate 5 broiler starter diets at dietary inclusion levels of 0, 10 and 20% raw and cooked wild cocoyam respectively. 180 7-day-old Anak broiler chicks were randomly allotted to the five treatment diets in a Completely Randomized Design (CRD) and each group was further subdivided into three replicates of 12 birds. Measurements recorded included weight gain, feed intake, feed conversion and protein efficiency ratios and economics of production. Results shows significant (p<0.05) improvement in feed intake, weight gain, feed conversion ratio and PER of birds fed cooked wild cocoyam meals. Marked (p<0.05) reduction was however, obtained in feed intake and feed conversion ratio of birds fed raw wild cocoyam diets. There was no significant (p>0.05) difference between birds fed maize-based (control) and cooked wild cocoyam diets. Results of this experiment indicated that cooking improved the nutritive value of wild cocoyam since birds fed cooked wild cocoyam diets produced best results than those fed raw wild cocoyam meal and that starter broilers could tolerate up to 20% dietary inclusion level of cooked wild cocoyam without any deleterious effect. Economics of production showed that cooked wild cocoyam diets were more profitable as regards the cost of feed per kg weight gain (N) and thus cost savings (%).

This work was carried out to evaluate the use of Bacillus subtilis probiotic C-3102 (10(10)cfu/g) in diets with or without growth promoters on the performance of broilers in the period from 1 to 42 days of age. It was used 1,200 Cobb line broilers, distributed in a complete randomized block with five diets: negative controller (without promoters); Bacillus subtilis (30 g/t ration); Bacillus subtilis (50 g/t ration); Bacillus subtilis (30 g/t ration) + colistin (10 ppm); avilamycin (10 ppm) + colistin (10 ppm). Each diet was evaluated in 10 repetitions with 24 birds. From 21 to 42 days of age, feed intake, weight gain and feed conversion were evaluated, and at 42 days of age, productive efficiency index was evaluated. At the end of the experimental period, it was observed an increase in the consumption of diet with the lowest dose of Bacillus subtilis (30 g) in relation to that one with Bacillus subtillis (30 g) + colistin (10 ppm). The values of weight gain obtained with the diet with the lowest dose of Bacillus subtillis (30 g) and with avilamycin (10 ppm) + colistine (10 ppm) were higher than those of the birds fed control diet (without promoters). For feed conversion, the best results were obtained by supplying diets containing 50 g of Bacillus subtillis, diet with 30 g of Bacillus subtillis + 10 ppm of colistin; and diet with 10 ppm of avilamycin + 10 ppm colistin. For the analysis of productive efficiency index, the best results were obtained with diets containing additives (probiotics and/or antibiotics) in comparison to the control diet. Bacillus subtillis C-3102 probiotic, at concentration 10(10) cfu/g, is an efficient substitute of antibiotics.

Three hundred 21-day-old broiler chicks were reared using a 3 x 3 factorial model in a completely randomized design with 10 treatment groups having 3 replicates of 10 birds each. The birds were raised on a commercial starter diet at the starter phase before being allotted into dietary groups in a 21-d feeding trial at the finisher phase. The interaction between treatment and varying inclusion levels of processed-fermented Jatropha curcas (L) kernel meals (JKM) on the performance of broiler chicks was investigated. Jatropha curcas kernels were subjected to three different processing methods, namely: raw defatted fermented meal (RDFM), cooked defatted fermented meal (CDFM) and lye treated defatted fermented meal (LDFM). Each meal was included at varying inclusion levels of 2.5%, 5.0% and 7.5% such that diet 1 (control) contained 0% JKM while diets 2, 3, 4 contained 2.5%, 5.0% and 7.5% RDFM, diets 5, 6, and 7 contained 2.5%, 5.0% and 7.5% CDFM and diets 8, 9, 10 contained 2.5%, 5.0% and 7.5% LDFM. Feeding differently processed-fermented JKM to these broilers did not (p>0.05) compromise the feed conversion ratio. The results indicated an improvement (p<0.05) in the weight gain of broiler chicks fed CDFM and LDFM at 2.5 and 5.0% inclusion levels respectively. There were significantly (P<0.05) elevated levels of alkaline phosphatase and creatinine in their blood serum. The kidney, lungs and proventriculus of birds fed CDFM showed significant differences (p<0.05) among the treatments. Therefore, finisher broilers could tolerate up to 5.0% inclusion level of LDFM.

This study aimed to evaluate the use of acacia tannin as a toxic metal adsorbent in the diets of broilers fed with the inclusion of golden mussel meal in substitution for calcitic limestone. In the first trial, 648 male 21-day-old animals were divided among six treatments and six replicates, with 18 birds per experimental unit, organized in a completely randomized design (DIC). The treatments were diets with different acacia tannin levels (0, 250, 500, 750, 1000, or 1250 g ton-1). The results indicated that 250 g ton-1 of tannin was not harmful to weight gain, final weight, or feed conversion. Tannin levels caused a decrease in carcass yield and fat deposition and an increase in liver size. For the second trial, 900 male broilers of 21 days of age were used and distributed in a DIC, with different levels of substitution of calcitic limestone by the golden mussel meal (0, 25, 50, 75, or 100 %) and supplementation or not with acacia tannins (250 g ton-1), with 5 replicates and each experimental unit being composed of 18 birds. The performance data show that the use of 250 g ton-1 of tannin is detrimental to bone performance and resistance and golden mussel meal can be used to substitute up to 100 % of the limestone in the diets without affecting the variables studied.

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.
