Chicken meat is the most preferential consumable edible nowadays. The present increased demand and supply of the chicken has resulted in the provision of chicken feed supplemented with all the basic macro and micronutrients to the poultry. As the consequence enhanced weight gain and growth of the chickens is observed that has allowed them to attain appropriate weight and size for consumption in...

groups: those who have chicken meat only allergy [1,3] , and a second group, a subset of 'bird– egg syndrome' with allergies to chicken meat, egg yolks, and other bird allergens from serum and feathers [4,5]. The most reported symptoms of allergy to chicken meat are urticaria [6] , oral allergy syndrome [7] , and non-IgE mediated colitis [8]. A few cases of anaphylaxis due to chicken meat have ...

chicken infectious bronchitis virus (ibv) causes severe respiratory and renal dysfunction in chickens. in the present study, we used reverse transcription-polymerase chain reaction (rt-pcr) to amplify the nucleocapsid (n) protein gene of strain massachusetts (mass) h120 of ibv that is commonly used in the vaccine production in iran. the pcr product with the expected size of 1.2 kb was cloned in...

The adjuvant effects of various lipopeptides and recombinant chicken interferon gamma (IFN-gamma) on the humoral immune response of laying hens was investigated in four immunization studies. We used the lipopeptide Pam3Cys-Ser-(Lys)4 (PCSL), the conjugate P-Th1 consisting of the lipopeptide P3CS and the T-helper epitope Th1 (FISEAIIHVLHSRHPG), and the conjugate P-Th2 of the lipopeptide P3CSS an...

An indirect Sandwich ELISA to measure growth hormone level in serum and milk of buffaloes was developed. The assay was based on purified anti rbST IgG raised in rabbits and chicken and rabbit anti chicken IgG horseradish peroxidase. The assay was validated in terms of sensitivity, specificity, precision and recovery. Parallelism was demonstrated between the standard curve and serially diluted s...

In the chicken, serum gamma globulin (CGG) is preferentially transferred by the follicular epithelium of the ovary to the developing ova. The concentration of gamma globulin in the yolk of the unfertilized egg is many times the concentration of chicken serum albumin (CSA). This transfer occurs largely during the 4 to 5 days preceding ovulation when the growth of the ovum is most rapid. Thus, in...

Avian species are renowned for their ability to conceal clinical evidence of disease until the pathological process is advanced. As in mammalian species, total protein (TP) measurement forms part of any routine biochemistry profile, often evaluated in conjunction with other biochemical and haematological parameters to assess the health status of the bird. However, significant variation in prote...

Twenty 35-wk-old chickens, including 10 Single Comb White Leghorn (SCWL) and 10 Rhode Island Red (RIR) hens, were used to examine the effects of egg and yolk weights on egg yolk antibody (IgY) production in the two strains of chickens immunized with BSA. The SCWL chickens had a greater (P < 0.01) percentage hen-day production and greater egg and yolk weights than did the RIR chickens. However, ...
