Twenty six Rhizobium strains were isolated from root nodules of Sesbania sesban (L.) Merr. collected from different regions of Andhra Pradesh. All the 26 Rhizobium strains produced indole acetic acid (IAA), but maximum amount was produced by only five strains in yeast extract mannitol  (YEM) medium supplemented with L-tryptophan. The strains were found to elaborate maximum IAA when fed with 2.5...

Although multiple genotypes of Campylobacter jejuni may be isolated from the same commercial broiler flock, little is known about the infection dynamics of different genotypes within individuals or their colonization sites within the gut. Single experimental infections with C. jejuni M1 (sequence type 137, clonal complex 45) and C. jejuni 13126 (sequence type 21, clonal complex 21) revealed tha...

Gouramy (Osphronemus gouramy) has very high economic value and is easy to cultivate. Currently there are about six strains that have been successfully cultivated based on their reproductive ability produce eggs, namely goose (soang, gouramy), jepun (japan, japonica), blue sapphire, paris, bastar (broiler) porcelain. One of the reasons for these differences in internal factors which can be seen ...

Phase-feeding (PF) has been effective in maintaining broiler growth while reducing production cost, but the effect on different broiler strains grown in a small-bird production scenario has not been assessed. The objective of this study was to evaluate 3 commercial broiler strains typically used in a small-bird production scenario to assess the effect of various debone times and PF on yield and...

Previous research has identified cecal and intestinal contents as sources for Campylobacter contamination of broiler carcasses in the processing plant. During the present study, we evaluated the crop contents of preharvest market-age broilers as a potential reservoir of field-derived Campylobacter in the processing plant. Crops were collected aseptically from 40 randomly selected market-age bro...

Among chicken strains, broilers are prone to pulmonary hypertension, whereas Leghorns are not. Relaxations to endothelium-dependent (ACh, A23187) and endothelium-independent [sodium nitroprusside (SNP), papaverine (PPV)] vasodilators were compared in preconstricted pulmonary artery (PA) rings from these chicken strains. ACh (10-7, 10-6, and 10-5 M)- and A23187 (10-6 and 10-5.5 M)-induced relaxa...
