the experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. a total of 150 day-old commercial broiler (cobb-500) was reared for a period of 35 days. there were five treatments including t0 (without rubber seed meal), t1 (10% rubber seed meal), t2 (20% rubber seed meal), and t3 (30% rubber seed meal) and t4 (4...

The effects of UV irradiation at a wavelength of 254 nm on the survival of Campylobacter jejuni on the surfaces of broiler meat, skin, and carcasses were studied. On broiler carcasses, the effects of UV were also studied in combination with activated oxygen. The surfaces were inoculated with varying counts of C. jejuni and treated with UV irradiation using doses ranging between 9.4 and 32.9 mW/...

objective: a research was carried out to investigate the effects of nettle (urtica dioica) powder (np) and essential oil (ne) on performance, blood metabolites, carcass characteristics and antioxidant stability in broiler chicks. methods: the treatments were t1: control diet, t2: control diet + 5g/kg np, t3: control diet + 10 g/kg np, t4: control diet + 5g/kg ne and t5: control diet + 10 g/kg n...

This experiment was conducted to compare the effect of litter amendments by using acidifier on growth performance, carcass characteristics and welfare of commercial broiler chicks along with its economical implication during winter season (DecemberJanuary months). A total of 180, day-old (Vencobb) broiler chicks were equally and randomly assigned to two litter abatements with alum and sodium bi...

High levels of phosphorus and pathogens in runoff are 2 major concerns following manure applications to fields. Phosphorus losses from fields following manure applications have been linked to the solubility of phosphorus in manure; therefore, by decreasing manure phosphorus solubility, a decrease in phosphorus loss in runoff should be apparent. The objective of this research was to develop a pr...

Bacterial counts from paired broiler carcass halves were examined for relationships between numbers and kinds of bacteria that might indicate fecal contamination. Broiler carcasses removed from a commercial processing plant just before chilling were split aseptically along the midline, and each side was rinsed in 400 mL of phosphate buffered saline for 1 min with either mechanical or hand shaki...

A total of 192 broiler chicks were used to evaluate the influence of dietary α-lipoic acid (ALA) on growth performance, carcass characteristics and meat quality of broiler chickens with the purpose of developing a strategy to prevent the occurrence of pale, soft, and exudative (PSE) meat and to improve the meat quality of broilers. At 22 d of age, birds were allocated to 4 ALA treatments (0, 40...

Campylobacter could be detected in the thoraco-abdominal cavity of broiler carcasses even if they were carefully eviscerated by hand with no evidence of intestinal rupture or leakage. If Campylobacter is present in the air sacs, which are unavoidably torn during evisceration, it could contaminate the thoraco-abdominal cavity of the eviscerated carcass. This study was done to determine if Campyl...

The aim of this study was to evaluate the ability of date pits (DP) to reduce the deleterious effects of aflatoxin B1 (AFB1) in broiler chicks. A total of 216 one-day-old male broiler chicks (Ross 308) were distributed randomly for nine treatments (with four replicates and six birds in each) for 35 days. The experiment included a 3×3 factorial arrangement of treatments involving three levels of...

Aim: A study was conducted to evaluate the effect of supplemental yeast culture (Diamond V XPC Yeast Culture; YC) in broiler diets on carcass characteristics and humoral immune response. Materials and Methods: A total of 240 one-day-old broiler chicks (Ross 308) were randomly assigned to four YC dietary treatments of 60 birds each. The dietary treatments were 0 (control), 1, 1.25 and 1.5 g YC/k...
