S OF PAPERS 217 were fed corn-soy diets containing 0, 0.5, 1.0 or 2.0% SP-1 for 28 days. Chicks were grown in an environmentally controlled room with feed and water provided ad libitum. At day 21, abdominal fat pads were collected from six chicks per treatment for FA analysis. At 7 and 21 days of age, 12 chicks from each treatment groups were intravenously injected with 1ml of 7% sheep red bloo...

Two experiments were conducted to evaluate the use of distillers dried grains with solubles (DDGS) from modern ethanol plants in broiler diets. Experiment 1 was a 2 x 2 factorial experiment with diets containing 2 levels of DDGS (0 and 15%) and 2 diet densities (high and low). The high- and low-density diets were formulated to contain 22% CP and 3,050 kcal MEn/kg and 20% CP and 3,000 kcal MEn/k...

How does face recognition emerge in the newborn brain? To address this question, we used an automated controlled-rearing method with a newborn animal model: the domestic chick (Gallus gallus). This automated method allowed us to examine chicks' face recognition abilities at the onset of both face experience and object experience. In the first week of life, newly hatched chicks were raised in co...

Methylmercury (MeHg) is an environmental pollutant known to induce neurotoxicity in several animal species, including humans. However, studies focusing the effects of MeHg poisoning in chicks were based on phenomenological approaches and did not delve into the molecular mechanisms. The purpose of this study was to evaluate the postnatal consequences of the in ovo exposure to MeHg on behavioral,...

This experiment was conducted to study the effect of dietary propionic acid on inhibitory effect of Salmonella gallinarum. Day-old 144 broiler chicks were randomly distributed into four dietary treatments, three replicates per treatment. The four dietary treatments consisted of 0.0, 0.6, 1.2, and 1.8% dietary propionic acid. Chicks were challenged orally on three days of age with 10 cfu Salmone...

SHAHEEN, M., I. AHMAD, F. M. ANJUM, Q-A. SYED and M. K. SAEED, 2015. Effect of processed rice bran on growth performance of broiler chicks from Pakistan. Bulg. J. Agric. Sci., 21: 440–445 Rice bran was added in broiler chicks feed by replacing 20% maize or 15% wheat. Signifi cant difference in weight gain, feed consumed, feed conversion ratio (FCR), dressing percentage, pancreas weight, feed co...

The health status of goshawk chicks (Accipiter gentilis) from the nests in the vicinity of Wrocław was evaluated. The research was conducted in spring 2001. Each nest was inspected three times at different phases of the reproduction period and the protocol included: the counting of eggs in each nest, clinical examination of chicks, collecting swabs from the crop and cloaca, blood and litter sam...

Five experimental groups were used to evaluate the efficiency of sodium bentonite (BNT) and ascorbic acid (AA) in reducing the toxicity of aflatoxin B1 in ElSalam chicks (Egyptian local chicks) diets. A total number of 450 unsexed one-day old chicks were wing banded, weighted and randomly assigned to 5 groups of five replicates (18 chicks/replicate). The experimental groups were as follow: 1) b...

Dietary Gly might become a limiting factor in all-vegetable diets fed to broiler chicks when low CP is formulated in combination with marginal levels of dietary Thr and Ser. A study was conducted to evaluate dietary Gly needs of broiler chicks. Day-old Ross 508 male chicks were placed in 32 floor pens (15 chicks/pen). Chicks were fed a common prestarter diet from 0 to 7 d of age and then fed a ...

The pathogenicity of Salmonella Kentucky, Salmonella Typhimurium, Salmonella Shubra and Salmonella Enteritidis were investigated in specific-pathogenfree chicks (SPF) and BALB/c mice. Mortality rates after the 1 st week of infection with the four serovars, only S. Typhimurium and S. Enteritidis produced a fulminate infection (88%) in each of the chicks and mice. The lowest mortality was seen in...
