Scanning and transmission electron microscopy were used in conjunction with normal microbiological cultural techniques to examine some aspects of contamination of broiler carcass skin by bacteria during processing. The autochthonous skin microflora of poultry, before processing, was mainly Micrococcus spp. which were located in accumulations of sebum-like substances on the surface of the stratu...

Two experiments were conducted to evaluate the effectiveness of two fermented rice/soy products (A and B) on fecal odor compound volatilization and performance parameters when included in broiler diets. In Experiment 1 the addition of fermentate B at 900 g/ton increased (p<0.05) d 21 body weight. The inclusion of both fermentates resulted in significant decreases (p<0.05) in multiple volatile o...

A total of 100 chicken samples (breast and thigh), 50 fresh carcass samples, 25 local frozen samples and 25 imported frozen samples were analyzed and the antibiotic residues were estimated by using Four Plate Test (FPT). Results revealed that 90 %, 88 % and 72 % of fresh, local frozen and imported frozen samples were positive for residues of different antibiotics, respectively. Samples were pos...

This study was conducted to determine the effects of four different dietary fat sources on performance, fatty acids composition of abdominal fat, thigh skin, breast and thigh muscle of broiler chickens. Soybean oil (SO), poultry grease (PG), beef tallow (BT) and a mixture of soybean oil with poultry grease (SPG 1 : 1) were used as fat source. A total 395, 4-day-old broilers were randomly assign...

This study was conducted to determine the prevalence and antimicrobial resistance of Salmonella isolates recovered from processed poultry. Four hundred eighty pre- and postchill whole broiler chicken carcasses were collected from a poultry processing plant between July 2004 and June 2005. Water samples also were collected at the entrance and exit of the chiller. After preenrichment, carcass and...

Background & Aim:Hypericum perforatum L. is native to Iran. This herb is one of the most important medicinal plants and had many medical effects.This experiment was conducted to investigate the effects of feeding Hypericum perforatum and protexin on performance, carcass characteristics and intestinal morphology Japanese quails. Experimental: ...

One hundred and twenty day old straight run coloured chicken (Chabro) were distributed into four treatments: T1-basal diet, T25% of basal diet replaced with Azolla meal on dry matter basis, T3Basal diet+Raw azolla after 4 weeks, T4T2+Raw azolla after 4 weeks. Average weekly weight gain of T1, T2 and T3 were significantly higher (P<0.01) than T4 birds at 2nd week. There was no significant differ...

To take advantage from genetic improvement of broiler chickens, updates must be made of the nutritional levels that promote maximum protein accretion and minimum fat deposition. The development of growth models is a valuable tool to understand nutrient deposition in poultry. This article presents experimental results and methodologies used to obtain prediction equations for true digestible lysi...

Broiler meat quality is one of the primary factors considered by the poultry industry. This study was conducted to estimate heritability and genetic correlation coefficients for meat quality traits in a single male broiler line. The meat ultimate pH (24 h after slaughter) and lightness presented the highest heritability estimates. Given the estimated genetic correlations, the pH measured at 15 ...

Mortality is an inevitable consequence of livestock and poultry farming. With a large livestock and poultry population of 513 and 729 million [1] respectively in India, animals die due to different diseases, accidents and disasters. Mortalities are usually thrown out on the roads, farm lands and rivers [2], thus creating different types of menace and environmental hazards. Strategies for carcas...
