The present study was conducted in semi-arid areas to examine the effect of feeding Moringaoleifera hay (MOH) on intake, digestibility, milk yield and its composition in lactating Nili Ravi buffaloes. Eight buffaloes of Nili Ravi breed were selected from the dairy herd on the basis of nearly similar lactation stage and body weight in the experiment. In this trial, buffaloes were blocked by parity and randomly assigned within block to one of two treatments for the duration of 17 weeks. An isonitrogenous and isocaloric concentrate was formulated and fed as a part of ration to all buffaloes with same quantity. While in the remaining part of the ration, one group was offered ad libitum Medicago sativa hay (MSH) and other group was provided MOH, respectively. Animals were fed at the rate of3% of their body weight per day.Dry matter (DM) intake was higher in buffaloes fed MOH diet than in those fed MSH diet. Digestibility of DM, organic matter, crude protein, neutral detergent fiber, acid detergent fiber and ether extract were significantly higher in buffaloes fed MOH diet as compared to MSH diet. Milk yield and 4% fat corrected milk, solid corrected milk, milk protein, and solid not fat were higher in buffaloes fed MOH diet than in those fed MSH diet; however, milk fat percent, milk fat yield (kg/day), lactose, total solids, specific gravity and milk pH were not affected by the treatments. The findings of the present study indicate that feeding MOH as a part of the ration not only has increased nutrients intake, digestibility and nitrogen balance but also improved milk production in lactating Nili Ravi buffaloes in semi-arid areas.

Isolation, Characterization and Serological Study of Avibacterium paragallinarum field isolates from Indian Poultry
V. Patil, D. N. Mishra and D. V. Mane
A total of 65 nasal swab samples from Infectious coryza suspected poultry birds were collected from different geographical locations of India during 2013 to 2015 and subjected to isolation of organism, biochemical and serological characterization of isolates by Page scheme along with confirmation by PCR. Biochemically, the isolates demonstrated abilities to utilize four sugars i.e. Glucose, Mannitol, Sorbitol and Sucrose, whereas two sugars Galactose and Trehalose were not fermented by them. All isolates were able to convert nitrate to nitrite. The isolates were negative for catalase, H2S production and Indole test and showed absence of oxidase activity. Among 17 field isolates of Avibacterium paragallinarum, along with serovar A and serovar C, there is presence of serovar B. Out of 17 isolates, the serovar C was prevalent with 47% and serovar A was 27%, whereas serovar B was found to be only 11% and 2 strains were non-typable. This is the first confirmed report of presence of serovar B in Indian poultry isolates.
