Background & Aim: This experiment was conducted to examine the effect of different levels of Echinacea purpurea (EP) in comparison with an antibiotic (flavofosfolipol) on total antioxidant activity (AOA) in serum of broiler chicks. Experimental: In this trial 240 one-day-old broiler chicks (Ross 308) were weighed and randomly assigned to the 5 treatment groups, each with 4 re...

The goal of this study was to compare the effects Bacillus subtilis and antibiotic enrofloxacin on growth performance, immune response, intestinal histomorphometry cecal Salmonella numbers in broilers challenged with S. gallinarum. Salmonella-free chicks (n = 240) were allocated four groups, comprising six replicates 10) each. Group NN not infected received no treatment. SN SE treated enrofloxa...

We investigated the growth of African Black Oystercatchers, Haematopus moquini, on Robben Island, South Africa, over three austral summers, 2001–2004. Oystercatcher chicks from our study population were found to have a Gompertz growth rate coefficient that was 2% less than predicted for body mass based on the equation for waders. The growth rate of body mass was observed to vary greatly between...

A.—Parents influence the phenotype of their offspring by determining the environment in which early development occurs. The many factors that affect growth in avian brood parasites provide an excellent context in which to examine how ecological variables and sex differences influence plasticity of early development. We used a model-selection approach to determine the most important varia...

Previous studies showed differences in in vitro heterophil function between parental (A > B) broilers and F1 reciprocal crosses (D > C). Our objectives were to (1) determine if in vitro variations translate to differences in resistance to Salmonella enteritidis (SE) and (2) quantitate cytokine mRNA in heterophils from SE-infected chicks. One-day-old chicks were challenged and organs were cultur...

The study aimed to investigate the effect of in ovo (IO) leptin injection on yolk sac concentration, embryo development, blood lipid metabolism, and biochemical parameters broiler chicks during early post-hatching period. Hatching eggs were weighed placed an incubator with 100 eggs/4 replications/group. groups were: non-injected group (C); 3 injected μl phosphate buffer solution (PBS); 0.5 (L0....

Three trials were conducted to evaluate the effect of moniliformin (M) on performance and immune function in chicks. Day-old chicks were randomly assigned to four dietary treatments (0, 50, 75, or 100 mg M/kg diet). In Trial 1, chicks were placed on treatments for 3 wk and were injected intravenously with 4.6 x 10(6) Escherichia coli on Day 21. Blood samples were collected at 60, 120, and 180 m...

In this study, it was evaluated that the growth performance of broiler chicken supplemented with edible P. florida mushroom, 20g/kg dried eoes and sajor caju mushroom. Day-old chicks from a single hatch were weighed individually divided into 4 groups six birds each at random. The will be given basic diet for starter (0–3weeks) finisher (4-6 weeks) rations. One group (G1) kept as control, while ...
