A study was carried out with White Rock female chicks to evaluate the possibility of using dietary Zn supplied as ZnO, to control feed intake and weight gain during the period of 1 to 3 wk of age. The levels of supplemental Zn tested were 0, 0.25, 0.50, and 1.0% (Experiment 1); 0, 0.65, 0.75, and 0.85% (Experiment 2); 0.7 and 0.8% (Experiment 3). The effect of Zn supplementation was compared wi...

Melon husks are shells usually discarded in large quantities (tonnage) as agricultural waste materials in different parts of Nasarawa State in Nigeria, thereby polluting the environment. An experiment was therefore conducted to determine the nutritional value and effect of utilizing melon husks meal in broiler diets as feed ingredient with or without wild mushroom (Ganoderma sp) and exogenous e...
This experiment was conducted to compare the effects of Roxarsone (Rox) and Bacitracin methylen disalicylat (BMD) on the performance of broiler chicks. A control corn-soybean meal diet without growth promoter was formulated according to NRC (1994) recommendation for starter (0-21d) and grower (22-42d) periods. The control diet was also supplemented with Rox (50 mg/kg diet ) BMD (55 mg/kg diet) ...
This experiment was carried out to investigate the effects of different levels chromium picolinate (CrPic) and chromium nanoparticles (nano-Cr) on the performance and immune function of broilers under heat stress condition. A total of 320 Ross 308 broiler chicks (from 21 to 42 days) were assigned randomly into eight treatment groups (four replicates per treatment, and 10 chicks per replicate) a...
Silymarin, the standardized extract of Silybum marianum, is used as a hepatoprotector in man, and is a potent antihepatotoxic agent. This study focused on the effects of a silymarin-phospholipid complex in reducing the toxic effects of aflatoxin B1 (AFB1) in broiler chickens. Twenty-one 14-d-old male commercial broilers were randomly allotted to 3 groups and treated as follows: basal diet alone...
SHAHEEN, M., I. AHMAD, F. M. ANJUM, Q-A. SYED and M. K. SAEED, 2015. Effect of processed rice bran on growth performance of broiler chicks from Pakistan. Bulg. J. Agric. Sci., 21: 440–445 Rice bran was added in broiler chicks feed by replacing 20% maize or 15% wheat. Signifi cant difference in weight gain, feed consumed, feed conversion ratio (FCR), dressing percentage, pancreas weight, feed co...
AIMS To determine the effect of antimicrobial selective pressure on the transmission of antimicrobial resistant and sensitive strains of Salmonella in poultry. METHODS AND RESULTS Eight pens housed 12 broiler chicks each. Two chicks in four of the pens were inoculated with a Salm. Typhimurium strain resistant to 12 antimicrobials (including tetracycline), and two chicks in each of the four ot...
The present study was conducted to investigate whether dietary essential oils could affect growth performance, relative organ weights, cecal microflora, immune responses and blood profiles of broiler chickens fed on diets containing different nutrient densities. A total of eight hundred-forty 1-d-old male broiler chicks were randomly allotted into twenty-eight pens (7 pens per treatment, 30 chi...
