six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal science university poultry farm to compare the effects of different levels of fish oil supplementation on performance of broilers in terms of feed intake, weight gain and feed conversion and carcass characteristics. the chicks were randomly distributed following a completely randomized desig...
The objective of this study was to determine the effect of different forage to concentrate ratios for fattening of Lohi lambs. For this purpose, 75 lambs were randomly divided into 3 groups A, B and C, with 25 lambs in each group. Berseem fodder was supplemented with concentrate at different ratios (forage to concentrate) as 75:25, 50:50 and 25:75 and fed to groups A, B and C, respectively for ...
________________________________________________________________________________ Abstract The aim of the present study was to assess the nutrient contents and potential feeding value in the diet of broiler chicks of the seed of three tree species, mesquite (Prosopis laevigata), Schaffneri ́s wattle (Acacia schaffneri) and the carob tree (Ceratonia siliqua). The dry matter (DM), ash, crude protei...
an experiment was conducted using 640 day-old sexed commercial broiler chicks (ross 308 strain) from 10 to 49 days of age. the experimental design was a completely randomized factorial one. the experimental units (pens) contained 20 chicks each and were allotted at random to 4 dietary treatments × two sexes with 4 replicates per treatment. four dietary treatments were formulated based on corn a...
this investigation aimed to assess genetics of body conformation and feed efficiency traits in a control line of rhode island red (rir) chicken taking single hatched out pedigreed 100 chicks at central avian research institute, izatnagar, india. data was analyzed by least squares analysis of variance. least squares means of chick weight (cw), body weight (bw), shank length (sl), keel length (kl...
This experiment was conducted to study the effects of using cotton-seed meal on the performance and carcass yield of broiler chickens at different ages. The experiment was performed in a completely randomized design with four treatments and five replicates for each treatment. The experimental treatments included the levels of 0, 3.5, 7, and 10.5% of cotton-seed meal in diets fed to chickens at ...
Two experiments were conducted to investigate the effect of dietary energy levels on the performance of Arian broiler chicks. Trial 1 was performed in summer and trial 2 in fall. Both experiments were accomplished in 5×2 factorial designs, involving 5 levels of dietary metabolizable energy and two sexes. Each of the 10 resulting treatments was replicated 4 and 3 times in trials 1 and 2, respect...

Forty-five, day-old broiler chicks with an initial average weight of 30.25±2.40 g were divided into three groups of fifteen animals each. The first group was placed on soybean-based (control) diet; the second group on raw (unfermented) T. catappa seed meal-based diet; and the third on A. niger-fermented T. catappa seed meal-based diet, for seven (7) weeks. Feed intake, feed conversion ratio, av...
