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.

Dietary Treatments

The present study was carried out for six weeks to investigate the effects of adding graded levels (0, 0.1 and 0.5%) of garlic (Allium sativum) powder to the basal experimental diet on the growth performance and carcass characteristics of broiler chicks. One hundred and eighty (n = 180) day old unsexed white commercial broiler chicks (Cobb-400) were randomly distributed into three dietary treatments of 60 birds/treatment and each treatment contained 4 replicates (15 birds/replicate). The dietary treatments were controlled basal diet (T1), and a diet supplemented with garlic powder at 0.1% (T2) and 0.5% (T3). Daily feed intake, weekly body weight, and residue leftover were recorded to calculate the feed conversion ratio (FCR). At the end of the experiment, six birds from each group were sacrificed to determine the carcass characteristics. Results revealed that dietary supplementation of 0.1% garlic powder (T2) significantly (p less than 0.01) improved body weight, body weight gain, feed intake and FCR as compared to birds supplemented with 0.5% garlic powder (T3) and control diet (T1). Dietary supplementation of 0.1% garlic (T2) resulted in significant (p less than 0.05) improvement in dressed yield as comparedto T3 and T1. On the other hand, comparable (p greator than 0.05) effect was observed on shrinkage loss, blood loss, feather loss, eviscerated yieldand relative weight of giblet. Thus, dietary supplementation of 0.1% garlic powder had beneficial effects on growth performance and dressed yield of broiler chicks.

Abstract Threonine (Thr) is the third limiting essential amino acid after methionine and lysine in cornsoybean based diets of broilers. Dietary imbalance of Thr, therefore, results in a poor growth performance in broilers. This review summarizes literature data on the known effects of dietary levels of Thr on growth performance, gut morphology, immunity and carcass characteristics in broilers. Due to continuous improvement in genetic potential and management practices for poultry production, dietary Thr requirements are changing. A number of studies have shown that supplementation of Thr in broiler diet at a higher level than the current NRC recommendation (0.74-0.81%), increases body weight gain, feed conversion ratio, and improves gut morphology, carcass quality and immune status, mainly by enhancing the functional capability of digestive system and immune organs (spleen, bursa, and thymus). According to the literature data discussed in this review, the minimal and maximal total dietary Thr levels for healthy birds reared in normal conditions were 0.67 and 0.90% for growth performance, 0.77 and 1.1% for a better gut health, 0.60 and 1.02% for immunity and 0.62 and 0.97% for better carcass characteristics. This background provides impetus to further investigate the exact level of Thr and its effects on growth performance, gut morphology, immunity and carcass characteristics in broilers.

This study evaluated the effect of phytogenic feed additives (Lemon peel, LP and Orange peel, OP) added singly or in combination to basal diets on the performance, gut morphology, haematology, serum biochemistry and lipid profile of broiler chickens. Four nutritionally adequate Corn-Soybean based diets were generated by the addition of LPand/or OPto basal diet. A total of 320, 1-d-old Marshall strain broiler chicks were given the basal diet supplemented with no additive (T1), 500g/tonne of LP (T2), OP (T3), or LP+OP (T4) in a study which lasted for 42 days. Growth performance was assessed weekly while gut and blood samples were collected at d 42 for examination. Data generated were analyzed using ANOVA with a P<0.05 level of significance. Results showed that chickens fed diets supplemented with LP and OP had similar (P>0.05) growth performance compared with the control group. Higher (P<0.05) duodenal and jejunal villus height were observed in chickens fed LP and OP, respectively. Phytogenics inclusion caused reduced (P<0.05) laminal propria depth at the ileum segment. Higher (P<0.05) PCV (30.00%), total protein (6.89 g/L) and albumin (3.67 g/L) were observed in chickens on LP+OP. Haemoglobin concentration (Hb) and RBC were not affected by the treatments imposed. Serum creatinine, uric acid and liver enzymes (AST and ALT) activity were reduced (P<0.05) with inclusion of LP and OP in broiler diets. Increase (P<0.05) HDL and decrease total cholesterol, LDL and triglycerides were observed in broilers fed LP and OP. Dietary inclusion of LP and OP had positive influence on gut morphology, RBC production, plasma protein reserves and lipid profile of broiler chickens.
