The effects of egg storage duration (ESD) and brooding temperature (BT) on BW, intestine development and nutrient transporters of broiler chicks were investigated. A total of 396 chicks obtained from eggs stored at 18°C for 3 days (ESD3-18°C) or at 14°C for 14 days (ESD14-14°C) before incubation were exposed to three BTs. Temperatures were initially set at 32°C, 34°C and 30°C for control (BT-Co...

Development of molecular-based immunotherapeutic strategies for controlling Salmonella Typhimurium (ST) infection in poultry requires a better understanding of intestinal and cecal cytokine responses. Accordingly, an experiment was conducted to measure changes in intestinal cytokine expression when commercial source broiler chickens were challenged with a nalidixic acid-resistant ST. Ross broil...

Campylobacteriosis is the most frequent zoonotic disease in humans worldwide, and the contaminated poultry meat by Campylobacter jejuni can be considered one of the important sources of enteric infections in humans. The use of probiotics, which can help to improve the natural defense of animals against pathogenic bacteria, is an alternative and effective approach to antibiotic administration fo...

This study was conducted to determine whether early age feed restriction improves heat tolerance in female broiler chickens. Chicks were brooded for 3 wk and then maintained at 24+/-1 C. On Day 0, chicks were assigned to one of four feeding regimens; each regimen was applied to four cages of chicks. The feeding regimens were 1) ad libitum feeding (ALF); 2) 40% feed restriction at 4, 5, and 6 d ...

Yellow discoloration often develops in rice kernels during post-harvest storage, due possibly to fungal activity. The present study examined the changes in nutrient composition taking place during yellowing of rice, and the effects of feeding rats and broiler chicks on a moderately yellow rice at 600 g/kg diet. Nitrogen content was found to be higher in rice grains that had become more yellow, ...

There is only little information how the age of chicks and the microbial activity in the hind gut of young broilers can affect the digestibility coefficients of amino acids. Ross 308 broilers were kept in battery cages and fed an experimental diet containing N-free components, soybean meal as the only protein source and TiO2 as a marker. Digestibility trials were carried out weekly from the 2 t...

One-day-old cobb-400 broiler chicks (240 nos.) were randomly assigned into four dietary treatments each with three replicates of 20 chicks. Four experimental diets were formulated as control diet (T1) without ginger or garlic, while, birds in group T2, T3 and T4 were fed with diets containing 1 % garlic, 1 % ginger and a combination of 1% of garlic and ginger, respectively. Ginger supplementati...

s of papers 35 142 Citric acid improves phytate phosphorus utilization in two breeds of chicks fed a corn-soybean meal diet. K. A. Rafacz*, C. Martinez, J. L. Snow, D. H. Baker, and C. M. Parsons, University of Illinois. Previous research in our laboratory has shown that citric acid improves phytate phosphorus utilization in crossbred chicks (New Hampshire x Columbian) fed a P-deficient corn-so...

Day-old chicks from 3 hatcheries were placed on bedding paper and brought to a commercial broiler farm between January and July 2016. Sixty-six samples of the paper, which were stained with meconium droppings of the chicks, were collected and examined for isolation of cephalosporin-resistant Enterobacteriaceae. Cefotaxime (CTX)-resistant Klebsiella pneumoniae (1 isolate) and Enterobacter cloaca...
