this research summarizes the data on benthic macro invertebrates collected from 25 points in the urmia lake wetlands during november 2008 to february 2009. the purpose of the study was to assess the effects of elevated salinity and nutrient (nitrogen and phosphorus) levels on macro invertebrate abundance and composition. a total of 32 taxa were collected, and the common taxa, including chironom...

This paper reports attempts to immunize domestic fowls against mosquito-borne infections of Plasmodium gallinaceum by means of (a) vaccination with inactivated homologous sporozoites; (b) injections of sera, both normal sheep serum, and serum from fowls chronically infected with the homologous Plasmodium, (c) combinations of both sporozoite vaccine and serum. It was possible to reduce the norma...

BACKGROUND The current study investigates the anti-stress effects of clove (Eugenia caryophyllus) extracts (0, 200, 400, and 600 mg/kg) on serum antioxidant biomarkers, immune response, immunological organ growth index, and expression levels of acute phase proteins (APPs); ovotransferrin (OVT), ceruloplasmin (CP), ceruloplasmin (AGP), C-reactive protein (CRP), and serum amyloid-A (SAA) mRNA in ...

This study was conducted to evaluate the effect of substitution of soybean meal (SBM) with dehulled-micronized peas (Pisum sativum) in diets of guinea fowl broilers on their growth performance, carcass yields, and fatty acid composition of meat. One hundred forty 1-d-old guinea fowl keets were randomly assigned to 2 dietary treatments, which were fed from hatch to 12 wk. The birds were fed 2 wh...

A mathematical model has been constructed to estimate the amino acid requirements for growing Taihe silky fowls in early stage. A requirement was taken as the sum of the needs for maintenance, for gain in carcass weight without feathers, and for the feathers. The maintenance requirement was considered to be the sum of the needs for replacing skin and intestinal losses and for the obligatory cre...

Biochemical polymorphism study is a method of determination of genetic variation. This variability could be a basis for selection and subsequent genetic improvement in farm animals. The polymorphism in the intron 1 of chicken growth hormone (cGH) gene was investigated in the Iranian native fowls by using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. The...

In the experiments reported in the preceding paper (p. 597) it was found that lactose, fed to hens, does not appear in the excreta in appreciable quantities until excessive amounts are administered—a finding thoroughly in agreement with our present knowledge of sugar-feeding in human beings. Since lactose is assimilated from the alimentary canal of chickens, and since assimilation of disacchari...
