Immune responses to genestein in male broiler chicks

Immune responses to dietary beta-glucan in broiler chicks during an Eimeria challenge.

Escalating consumer concerns regarding pathogen resistance have placed the poultry industry under mounting pressure to eliminate the use of chemotherapeutic agents as feed additives. One possible alternative receiving increased attention is the use of immunomodulators such as β-glucan. A study was conducted to investigate the effects of a yeast-derived β-glucan (Auxoferm YGT) on broiler chick p...

performance, immune responses of heat stressed broiler chicks in response to dietary levels of propolis

this experiment was performed to investigate the effects of propolis and chromium picolinate on performance and immune response of broiler chicken under heat stress conditions. treatments included different levels of propolis (500, 1000, and 1500 mg/kg) and chromium picolinate (1500 µg/ kg) along with a control group. a completely randomized design was taken into account with 4 replicates of 10...

Effect of Different Levels of Vitamin A in Broiler Chicks on Immune Response to ND Vaccine

Effects of fumonisin B1 on selected immune responses in broiler chicks.

Three experiments were conducted to evaluate immune responses in chicks fed fumonisin B1 (FB1). Day-old male chicks were randomly allotted to dietary treatments: 0, 50, 100, or 200 mg FB1/kg diet. In Experiment 1, chicks were fed diets for 3 wk and were injected intravenously with 4.6x10(6) Escherichia coli on Day 21. Blood samples were collected at 60, 120, and 180 min postinjection, and liver...

Immune Responses in Broiler Chicks Fed Propolis Extraction Residue-supplemented Diets

This study was conducted to evaluate the effect of inclusion of propolis extraction residue in the feed of broilers from 1 to 21 d of age on phagocytic activity of macrophages, cutaneous basophil hypersensitivity response to phytohemagglutinin, antibody production against Newcastle disease, lymphoid organ weight and hematological profile and to determine the optimal level of inclusion. 120 chic...
