The effect of ochratoxin A (OA) on the body weight, feed intake, and feed conversion was investigated in broiler chicken fed dietary levels of OA at 0, 1, and 2 ppm for 28 days from hatch. Feeding OA significantly reduced the growth rate of broiler chicken. The reduction was observed from the first week onwards in OA-treated groups. Feed consumption and feed conversion also showed a diminishing...

The suitability of leaves for use as broiler litter was evaluated in four 49-d floor pen trials of 150 Avian × Avian female chickens each. In each trial, 25 broiler chicks were weighed and randomly assigned to one of six pens at a density of 1.2 m2 per bird. There were two replicates of each of the following three treatments: 1) pine wood shaving (control), 2) a mix of 50% pine wood shaving and...

To investigate the effect of dried Bacillus subtilis culture on growth, body composition and hepatic lipogenic enzyme activity, female broiler chicks were fed on either no additive (control) or dried B. subtilis-culture-supplemented commercial diets (215 g crude protein/kg, 12.85 MJ metabolizable energy/kg) at 10 or 20 g/kg diet for 28 d from 14 to 42 d of age. Body weight, and moisture, fat, p...

A feeding study evaluated whether standard broiler diets prepared with grain derived from Syngenta Seeds NK Brand Bacillus thuringiensis (Bt) Corn hybrids had any adverse effects on male or female broiler chickens. Four kinds of corn grain were used in this study: (1) grain from the Bt-expressing field corn hybrid N7070Bt, (2) grain from the N7070Bt hybrid that had been sprayed with Liberty bra...

1,001 faecal samples were obtained from 89 sheep (lambs and adult), 184 goats, 190 horses, 178 rabbits, 110 camels, 200 broiler chicken and 50 turkeys housed in farms from different localities in Tunisia. All samples were analysed for Cryptosporidium oocysts by microscopic examination of smears stained by modified Ziehl Neelsen technique. The parasite was detected in ten lambs and adult sheep (...

potential for decreasing the amount of symbiotic N2 fixation. In contrast, Lory et al. (1992) reported that Although most of the N required by soybean [Glycine max (L.) topdressed manure addition to alfalfa (Medicago sativa L.) Merr.] is provided through the process of symbiotic N2 fixation, supplemental N using broiler litter may boost soybean grain yields. The efdid not affect N2 fixation. Ga...

Gejala umum terjadinya sindrom ascites pada ayam broiler adalah berupa akumulasi cairan yang berlebihan di rongga peritoneal yang menyebabkan peningkatan tekanan pembuluh arteri pulmoner. Kondisi ini dapat menyebabkan kematian akibat kurangnya suplai oksigen untuk kebutuhan metabolis tubuh. Angka kematian akibat Ascites pada ayam broiler adalah sebesar 5%. Sindrom ascites dapat dicegah dengan m...

Effects of deglucosing and antioxidant treatments on quality characteristics of broiler blood meal were studied. Broiler blood was dried and ground with deglucosing and antioxidant addition. The non-deglucosed blood powder was darker, less red and yellow in color than those of the deglucosed. Yeast deglucosed blood meal had the lowest lysine availability as measured by the ̄uorodinitrobenzene me...

The most prevalent diseases in country poultry industry that will infect broiler chickens epidemic; be disrupts the liver function. The liver is an important diagnostic organ in broilers is raised and on the other hand, Because of speed up the metabolism in broiler chickens in order to increase production and efficiency, The liver is an important center involved in the metabolism, and the impor...

This study applied a non-parametric method to analyze the efficiency of farmers, discriminate efficient farmers from inefficient ones and to identify wasteful uses of energy in order to optimize the energy inputs for broiler production. Data were collected from 44 broiler farms in six villages in Yazd province (Iran) by using a face-to-face questionnaire performed in January– February 2010 peri...
