In this study, we examined the effects of formic acid administration to the drinking water on performance, intestinal microflora and carcass contamination in male broilers. A total of 312 day-old male broiler chicks were allocated to two groups with three replicates. The first group (control) received normal drinking water (pH 7.4) during the experiment. The second group consumed acidified drin...

Aflatoxins can easily grow and develop in many feed ingredients influence the risk of several animal chronic diseases.The present study aimed to evaluate effect bentonite inclusion on performances, carcass yield, giblet, blood constituents broiler-fed contaminated aflatoxin through a meta-analytical approach. A database was developed based scientific publications that were searched using search...

Betaine is donor of methyl groups and can partially replace methionine in diets for this purpose. The objective of this study was to evaluate three sources of betaine in partial substitution of methionine supplement in broiler diets. The Cobb-500 broiler chickens were allocated in a completely randomized experimental design with 5 treatments and 7 replicates of 49 birds each. The positive contr...

the objective of the present study was to determine the effects of different levels of l-arginine in the diet on the growth performance, carcass traits, and blood parameters of female ross broiler chickens within their starter period. a number of, 192 day old female ross broiler chickens were fed with 4 dietary treatments in a completely randomized design, each dietary treatment had 4 replicati...

l-carnitine as a water soluble derivative of lysine has a crucial biological role in lipid metabolism. present experiment was conducted to study the effect of l-carnitine supplementation into broiler and/or breeder diets on broilers' performance, blood related factors, carcass characteristics and immune system. l-carnitine was added to the broiler breeder's diets at levels of 0, and 6...

19-33 ABSTRACT The objective of the research was to compare finishing beef steers on high corn (Zea mays L.) silage diets in which the corn was produced under conventional and sustainable systems. The conventional corn forage was produced on a given area for 5 yr, using conventional practices, alternating with 5 yr of alfalfa (Medicago sativa L.) The sustainable system corn forage was produced ...

Bacteriophages represent a group of viruses that specifically infect and replicate in bacteria and could potentially be used to reduce recovery of Salmonella from poultry carcasses. Bacteriophages were isolated from municipal wastewater in the presence of Salmonella enteritidis phage type 13A (SE). In the first 2 experiments, commercially processed broiler carcass rinse water was pooled and div...

The experiment was conducted to determine the effect of microbial phytase in Ca deficient and available aP diets on broiler performance and some blood traits. Three hundred day-old chicks (Ross 308) were distributed into five equal groups with two replicates. The control diets (T1) contained Corn-SBM, 0.9% Ca and 0.40% aP without enzyme, whereas T2, T3, T4 and T5 contained Corn-SBM, 0.60% Ca an...

Release of bacteria from individual broiler carcasses in warm water was measured as a model of bacterial contamination of scald water. Immediately after shackling and electrocution, feathered and genetically featherless broiler carcasses (n = 24 of each) were immersed individually in 42 degrees C, air-agitated tap water for 150 s. Although any visible fecal material expelled as a result of elec...
