Background: Nutritional strategies targeting improvement of poultry performance and disease prevention are currently being developed and in this respect the dietary intake of spiced essential oils and pre-biotics in raising broilers is receiving attention. OBJECTIVES: This study was conducted to compare the effects of diet containing ginger essential oils (GEO) and mannan-oligosaccharide (MOS) ...
this research was conducted to evaluate the effects of synthetic methionine replacement with herbal methionine (hm) on performance, blood biochemical parameters and carcass characteristics in broiler chicken. a total of 280 8-old ross 308 male chicken were randomly assigned to 7 dietary treatments: control, in which 100% methionine requirement was supplied form dl-methionine, and in treatments ...
two hundred and forty hubbard classic broiler chicks were used in a 35 day trial at chittagong veterinary and animal science university farm, bangladesh to study the effects of supplemental choline chloride on performance parameters, carcass characteristics and their association in commercial broiler. all birds had free access to ad libitum feeding. birds were fed four types of diet i.e. diet w...
The efficacy of bacitracin methylene disalicylate (BMD) in the management of necrotic enteritis (NE) when fed in combination with narasin was investigated in a floor-pen study of 2,000 broiler chickens using a Clostridium perfringens inoculum challenge model. Treatments consisted of 1) nonchallenged-nonmedicated; 2) challenged-nonmedicated; 3) challenged-narasin (70 ppm); 4) challenged-BMD (55 ...
Preventing leg disorders in broilers, without changing their body weight at slaughter age and their rearing time is a challenge for poultry production. The method of prevention we studied consisted in alternating the distribution of different diets. This kind of diet schedule is called “sequential feeding”. The alternation of poorand rich-lysine diets was used in order to reduce early growth an...
Cephamycin C is a beta-lactam antibiotic that has broad gram-negative activity and is resistant to degradation by beta-lactamases and safe for use in animals. In colostrum-fed calves infected with Escherichia coli strain B44, cephamycin C administered by gavage at 31.3 to 1,000 mg per calf (0.75 to 24 mg/kg) twice a day for 6 days starting at 20 h post-inoculation eliminated the diarrhea and re...
this experiment was conducted to evaluate the effects of dietary salvia mirzayanii supplementation on performance, carcass characteristics, internal organs and cecal microbial population in broilers. a total of 200, one-day-old broiler chicks (ross 308) were fed five experimental diets containing different levels of s. mirzayanii (zero, 0.25, 0.50, 0.75 and one percent of diet) until 42 days of...
This study was conducted to evaluate the effects of diet containing inclusion of carvacrol, menthol and thymol at 400, 200 and 200 mg/kg, respectively, on performance, cell-mediated and humoral immune response using 96 broiler chicks in a completely randomized block design in 12 replicates of 2 birds each. Feed intake reduced in birds received diet containing menthol during days 14 to 42 o...
an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...
