Different Levels

A study was conducted to determine the effect of different levels of okra (Abelmoschus esculentus L.) seed powder (OSP) in diets on performance, carcass characteristics, some blood parameters, and gut microbial populations in broiler chickens. For the present experiment, 216 day old chicks were randomly divided into four groups, each group consisting three replicates of 18 chicks in a completely randomized design. Four diets were formulated with diet 1 as the basal diet (control), while 2, 3, and 4 were supplemented with OSP at 1, 2 and 4 %, respectively. The results revealed that the highest final live body weight, accumulative weight gain, and better feed conversion ratio was achieved in birds fed with 1 or 2 % of OSP. Feed intake and carcass characteristics were similar among groups. The highest relative weight of the spleen and cecum was observed in the control group, while the lowest value was observed in birds fed with 4% and 2% OSP, respectively. The longest length of the gastrointestinal tract was seen in 2% OSP compared to other groups. Serum cholesterol and ALT activity were decreased as compared to control diets. The group fed with 2 % OSP showed higher albumin levels compared to those fed with 1% of OSP. The population of total bacteria and Escherichia coli in jejunum digesta of OSP supplemented broiler chickens was reduced, meanwhile, there was an increased in lactic acid bacteria counts as compared to control. Therefore, 1 and 2 % okra seed powder in the diet of broiler chickens was able to improve the growth performance.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

The growth performance, blood parameters and production cost of two hundred and fifty two (252) Abor acre plus broiler chickens fed sweet orange peel meal (SOPM) with and without enzymes were investigated. The experimental diets consist of control (T ), maize was 0 replaced with SOPM at 15, 20 and 25 % without exogenous enzymes to form T , T and T 1 2 3 respectively, and another supplemented with exogenous enzyme to form T , T and T 4 5 6 respectively. The birds were randomly allocated to seven treatment groups replicated three times to have 12 birds per replicate and were fed experimental diet ad-libitum for eight weeks. Result showed that broiler chickens fed control diet (T ) had significantly (P<0.05) 0 higher final weight (FW) of 2.44kg, weight gain (WG) of 42.91, feed intake (FI) of 86.53, better feed conversion ratio (FCR)of 2.01 and protein conversion ratio (PCR)of 0.44 compared to other dietary treatments. Broiler chickens fed T and T had significantly 1 4 (P<0.05) higher final weight of 1.98 and 1.98 kg, weight gain of 34.69 and 34.71 g and feed intake of 78.35 and 81.63 g respectively while significantly (P<0.05) least values of 1.75 and 1.80 kg final weight, 30.73 and 31.49 g weight gain and 69.47 and 71.84 g feed intake respectively were recorded in broiler chickens fed T and T . Haematological indices namely: 2 5 PCV, RBC, WBC and Hb were not significantly different (P>0.05) but MCV, MCH, MCHC, lymphocytes, heterophil, eosinophil and monocytes differed significantly (P<0.05). Serum biochemical indices namely total protein, albumin, globulin and uric acid were significantly (P<0.05) influenced by the experimental diets. Though, there was no detrimental effect of SOPM and enzyme on production cost as profit was made at all replacement levels of SOPM with and without enzyme treatment, but profit per bird (N) and cost to benefit ratio revealed the superiority of the broiler chickens fed control diet (T ). Based on the results obtained, 0 SOPM can replace maize up to 25 % without posing any deleterious effect on the broiler chickens growth performance, blood parameters and production cost. However, the cost to benefit ratio was compromised with the use of SOPM.

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P < 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P < 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P < 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P < 0.05; and Control vs BSR diets, linear, P < 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.

Pharmacologically Active

AbstractSalbutamol (albuterol) is a β-adrenergic agonist marketed as a racemic (50: 50) mixture of R- and S-enantiomers (rac-salbutamol). Since only R-salbutamol is pharmacologically active and S-salbutamol has a longer half-life in humans, we examined R-salbutamol as a performance enhancer and repartitioning agent in domestic chickens. The effects of feeding diets containing R-salbutamol (5, 10 and 15 mg/kg diet) and rac-salbutamol (10 mg/kg diet) from day 21 to 42 post hatching on growth performance, carcass characteristics and tissue concentrations of R- and S-salbutamol in male and female broilers were compared with a control diet. R-salbutamol in the diet lowered the weight gains in both sexes, but the magnitude of reduction was greater in males as indicated by a significant R-salbutamol ✕ gender interaction. R-salbutamol also lowered food intake and improved food conversion ratios in both sexes. The relative weights of breast muscle and leg muscle were significantly increased and the relative weight of the fat pad was significantly decreased in birds of both sexes given diets containing R-salbutamol. Carcass protein content increased and carcass fat content decreased but the differences were not statistically significant. A significant dose-response effect was observed for tissue concentrations of R-salbutamol in all tissues, except the fat. Performance and carcass parameters in chickens given the 5 mg/kg R-salbutamol diet were similar to those given the 10 mg/kg rac-salbutamol diet, but tissue concentrations of R-salbutamol were lower. Chickens given the 10 mg/ kg rac-salbutamol diet had higher tissue concentrations of salbutamol than chickens given the 10 mg/kg R-salbutamol diet and higher concentrations of S-salbutamol than R-salbutamol in liver and leg muscle. Overall, these results demonstrate that R-salbutamol is an effective repartitioning agent in broiler chickens.
