The study was aimed at determining the effects of Vitamin C and electrolyte on growth and meat yield of broilers in a hot humid environment. A total of 60 straight run day old Cobb 500 broilers were reared up to 35 days of age and fed ad libitum on a starter diet up to 12 days and thereafter, on a grower diet. The broilers were divided into 4 treatment groups. One group (15 broilers) without Vitamin C and electrolyte supplementation was considered as control. In other three groups were provided 135ppm Vitamin C, 1250ppm electrolyte and 135ppm Vitamin C + 1250ppm electrolyte in drinking water respectively as supplement. Feed intake, body weight, feed conversion and survivability were similar in broilers that received different levels of Vitamin C and electrolyte supplementation in drinking water. Feed cost per broiler and per kg broiler increased due to the addition of Vitamin C and electrolyte. Dressing yield, breast meat, total meat and wing meat were (P<0.05) higher in broilers that received Vitamin C in drinking water than those of control, electrolyte and Vitamin C + electrolyte supplemented groups. No differences (P>0.05) were found in breast: dark meat, thigh meat, drumstick meat and abdominal fat which could be attributed to either Vitamin C or electrolyte supplementation. It implies that deficiency of Vitamin C may be related to reduce meat yield of broilers in a hot humid environment. However, further experiment using several doses of Vitamin C with large number of broilers may be conducted to confirm the appropriate doses of supplementation.

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.

In the 20 d experiment, the influence of different concentration and supplementation period of commercial blackcurrant extract (BC) in the broiler diets on the oxidative stability of breast and thigh meat, as well as selected performance indices, was investigated. A number of 120 fifteen-d-old Hubbard Flex male chicks (initial BW 363.5 ± 22.9 g) were randomly allocated to five groups: the control and four treatments (6 replicates, 4 birds per cage in each group). The BC extract was administrated to treatment groups at two concentrations (1.25 and 2.5 g/kg) and in different periods within the trial (i.e., from 15 to 35 d and from 25 to 35 d of life). Body weight gain (BWG) and feed conversion ratio (FCR) were determined during the 20-d experiment. At d 35, two randomly selected birds from each cage were decapitated, and pectoral and thigh muscles were collected. Extent of lipid oxidation after storage at chilling (2-3°C, 1, and 5 d) and freezing conditions (after 90 d, −18°C) was determined. The chickens’ growth performance and FCR were not affected by the concentrations and periods of BC supplementation. The enrichment of grower diet with 1.25 g/kg of BC extract reduced the malondialdehyde (MDA) formation in frozen thigh muscles (P<0.05), and this effect tended to appear (P<0.089) irrespective of duration of the supplementation period. Significant extent of lipid oxidation process was found in 1-d-chilled pectoral muscles of chickens receiving BC diet for 20 d or diet containing 2.5 g/kg of the extract. The results showed that BC extract may be an efficient source of antioxidants in chicken diet, which may increase oxidative stability of frozen dark meat. However, the conditions and ability of some polyphenols to initiate oxidation processes have not been fully understood and further studies are required.

An experiment with broiler chickens was conducted to compare the relative bioavailability of liquid methionine hydroxy analogue free acid (MHA-FA) with that of DL-methionine (DLM) during fattening to 35 days of age. Ross 308 male chicks were allotted to 9 treatments, each consisting of six replicates of 140 birds/pen. Four graded levels (0.04, 0.08, 0.16, and 0.28 %) of MHA-FA or DLM products (weight/weight comparison) were added to a maize-wheat-soyabean meal basal diet deficient in sulphur amino acids. The criteria of response were body weight, feed conversion ratio, carcass yield and breast meat yield. Significant responses to graded levels of both methionine sources were observed in all response criteria. Using a multi-exponential model describing the dose-response relationships, the bioavailability estimates of MHA-FA relative to DLM on a weight-to-weight basis were 68, 70, 54 and 59 % for body weight, feed conversion, carcass yield and breast meat yield, respectively. If MHA-FA was compared with DLM on equimolar basis its bioavailability was 77.7, 79.0, 59.3 and 64.6 for body weight, feed conversion, carcass yield and breast meat yield, respectively. The bioavailability of MHA-FA for carcass yield and breast meat yield was significantly (P < 0.05) lower than that of DLM on a weight-to-weight and on equimolar basis.

Abstract Background: Valine and isoleucine are similar in chemical structure and their limitation in broiler chicken diets. To evaluate their limitation and interactive effects, multivariate assessment nutrition studies for the branched-chain amino acids (BCAA) are needed. A three level (-1, 0, +1), three-factor Box-Behnken design study was conducted to assess dietary BCAA ratios to lysine of 65, 75, and 85 for valine, 58, 66, and 74 for isoleucine, and 110, 130, and 150 for leucine in male and female Lohman Indian River broilers from 22 to 35 d of age.Results: Live performance of male broilers was not affected by BCAA level. However, male broilers fed increasing isoleucine had improved (P = 0.07) carcass yield as leucine and valine were reduced. Female broilers had improved body weight gain (P = 0.05) and feed conversion (P = 0.003) when leucine and isoleucine were at their lowest levels, independent of valine, but increasing leucine impaired live performance and warranted concomitant increases in isoleucine to restore responses. Increasing dietary isoleucine and valine in female broilers increased breast meat yield (P = 0.05), but increasing leucine tended to diminish the response.Conclusion: The female Lohman Indian River broiler is more sensitive to BCAA diet manipulation than males. Specifically, as dietary leucine is increased in female broilers, dietary isoleucine increases were needed to offset the negative effects. Both increases in dietary valine and isoleucine improved breast meat yield in female broilers, but only when birds were fed the lowest dietary leucine.

The study was conducted with attempts to determine the effects of autosomal dwarf (adw) gene introgression from Indigenous dwarf chicken (IDC) to White Leghorn (WLH) and Fayoumi (Fay) on growth and meat yield characteristics. Experiment was carried out at the Poultry Farm of Bangladesh Agricultural University (BAU), Mymensingh for a period of 28 months from March 2013 to June 2015 under intensive management condition. In this study, the di-allele crossing between WLH, Fay and IDC produced 4 up-graded chickens viz. IDC♂ × WLH♀, WLH♂ × IDC♀, IDC♂ × Fay♀ and Fay♂ × IDC♀. The up-graded F1 generations were mated intersex to access their productivity. The up-graded F1 generations were mated intersex to access their productivity. Pre-slaughter live weight of birds significantly (P<0.001) varied by genotype, sex and genotype × sex interaction. Percentage of thigh meat, drumstick meat, dark and total meat weights was significantly influenced by genotype. Although meat yield parameters of male birds in relation to live weight were found higher than their female birds, some parameters like breast meat, liver, giblet and total meat yield were found higher in female birds than that of male birds of all genotypes. However, meat yield parameters like percentage of thigh, drumstick and total meat yield were the highest in IDC♂ × Fay♀ and Fay♂ × IDC♀ and the lowest in IDC♂ × WLH♀. From the above findings, Fayoumi mediated dwarf genotypes showed better meat yield characteristics than Leghorn mediated dwarf genotypes.

This study determined the effects of dietary intake of Moringa Oleifera (M. oleifera) leaf meal on growth performance of pullets. Two hundred and forty Isa Brown day-old chicks were randomly allotted to 4 different treatment groups and each treatment had 3 replicates of 20 chicks each. At 4th week of age, birds in group 1 (T1)were fed with 16% crude protein (CP) grower diet (control feed; 0.0% M. oleifera) whereas birds in groups 2 (T2), 3 (T3) and 4 (T4) received the control feed supplemented with 2.5%; 5.0% and 7.5% M. oleifera leaf meal, respectively. Results indicate that although intake of M. oleifera leaf meal did not affect final body weight and weight gain of the pullets (P greater than 0.05), feed intake of the pullets declined significantly (P less than 0.05) as the amount of dietary M.oleifera intake was increased from 2.5% to 7.5%. Feed conversion ratio of T4 group was better (P less than 0.05) than those of control birds.

Significant Difference

A total of 144, day old as hatched Cobb-500 broilers were fed adlibitum basis on a diet with 0%, 0.5%, 1.0% and 1.5% of Black Cumin Seed Meal up to 35 days of age to compare the effect of BCSM as herbal growth promoters on growth performance, meat yield characteristics and profitability of broilers. The experimental diets consisted of broiler starter and broiler grower, which were fed from 0-16 and 17-35 days of age, respectively. Diets supplemented with 1.5% BCSM showed significant effect on live weight at 21, 28 and 35 days of old in broilers in various groups as compared to that of control group. Better feed conversion (2.02) also noticed at 1.5% level of BCSM at early stage (14 days of old) of broilers. There was no significant difference (P>0.05) among the average live weight, dressing yield, thigh meat, wing meat, heart, gizzard liver, at 0%, 0.5%, 1.0% and 1.5% level of BCSM diet. But difference found within breast meat, drumstick meat, abdominal fat and skin of broilers at 1.5% level of BCSM diet. It may be concluded that supplementation of BCSM at 1.5% had the highest significant effect (P<0.01) on feed cost (Tk kg-1 b), production cost (Tk kg-1 b) and profit (Tk kg-1 b) and lower mortality. So that 1.5% BCSM in diets can be used for economic and efficient broiler production than 0.5% and 1.0 % level.SAARC J. Agri., 13(2): 151-160 (2015)

A study was conducted to determine the meat production potential of Pekin (P) x Pekin (P), P x Desi (D) and P x Jinding (J) ducklings up to 8 weeks of age. 54 day old ducklings were randomly allocated to 3 genotypic treatments having 3 replications in each genotype. One duckling from each replication was dissected to determine the meat yield. The initial and final live weight was found highest (P<0.01) in P X P, followed by those of P X D and P X J ducklings respectively. Feed conversion was poor in P X J, better in P X P and best in P X D (P<0.01). However, feed conversion for all genotypes decreased with the advance of age. At all ages except 1st week, better feed utilization was observed in P X D crossbred than that in P X P and P X J. Higher breast meat was observed in P X P (P<0.05) than in P X D and P X J. Thigh meat was found higher (P<0.05) in P X P and P X D than that in P X J. Considering the growth performance (growth rate and feed utilization) and meat yield characteristics, it may be concluded that crossing of Pekin with local ducks might produce a suitable genotype to improve meat production potential of duck to reared under Bangladesh condition.
