  A systematic investigation was performed on the outbreaks of Infectious Bursal Disease (IBD) using data compiled during the years 1997 and 1998 from 50 broiler farms in Mirpur and Kotli districts. Average mortality due to IBD was 15.31±1.04% with a coefficient of variation of 48.04%. Farms located at various places and vitamin supplementation had no effect on mortality caused by IBD. Season, floor space/broiler, age of the bird, immunization schedule, interval between two batches, presence of coccidiosis in a flock and hygienic status of the farm had a significant effect (p<0.01) on prevalence of IBD. Higher losses (p<0.05) were found due to IBD in winter (19.84±2.10%) than those tabulated in spring season (9.00±2.74%). Losses were found to be higher (p<0.05) in over crowded houses (20.34±3.93%; <0.09m2/broiler) than in under (12.56±2.53%; >0.09m2/broiler) or optimally utilized housing (13.04±1.06%; 0.09m2/broiler). Significantly higher (p<0.05) losses were found in broilers at the age above 32 days (17.66±1.51%) than in broilers at 19-23 days of age (12.42±1.97%). Prevalence of IBD was higher (p<0.05) in those flocks immunized only once in their production life (23.03±1.27%) than in those produced under a standard immunization schedule (7.61±4.89%). Losses due to IBD were also higher when the duration between two batches was one week (22.28±10.28%) than at four week duration between two batches (12.80±2.78%). Insignificant differences were assessed in losses due to IBD when inter flock interval was either 2 or 3 week periods. Significantly higher (p<0.05) losses were found due to IBD in flocks experiencing coccidiosis problem (17.90±1.20%) than those having no coccidiosis problem before the onset of IBD (12.73±1.85%). Losses were less in flocks maintained under good hygienic conditions (6.03±1.33%) than those under poor hygienic conditions (21.63±2.19%). Mean economic losses due to IBD per broiler flock of 1734.50±119.91 and a flock of 1000 birds were Rs. 7846.87±1169.81/ and Rs. 4523.99±447.56/, respectively. Economic losses/year for the aforementioned flocks was Rs. 31701.38±2345.36/- and Rs. 18276.96±2388.91/-, respectively. Optimal utilization of floor space/broiler, protection of birds from extreme climatic conditions, following recommended immunization schedule, maintenance of good hygienic conditions at the farm and a flock interval of at least more than one week are suggested as important factors for reducing losses due to IBD in broilers in Mirpur and Kotli districts of Kashmir.

  Morbid materials from 25 commercial broiler breeder farms located in Abbottabad and Mansehra districts were collected over one year period to investigate prevalence of Fowl cholera and study efficiency of various organs to be used as diagnostic tools for fowl cholera. Overall incidence of Fowl cholera was (0.80?0.26%) with a coefficient of variation of 231.45%, indicating significantly higher incidence (1.07?0.62%) in Mansehra than in Abbottabad (0.53?0.34%). Significantly (p<0.05) lower incidence of Fowl cholera was found in vaccinated (0.15?0.26%) than in non-vaccinated flocks (1.45?0.63%). Higher incidence (1.35?0.38%) of Fowl cholera was found in farms previously exposed to Fowl cholera disease as compared to those in which there was no previous incidence (0.25?0.29%). Fowl cholera was found positively (p<0.01) and significantly associated with flock age (b=0.074661?0.03389) but negatively associated with egg production (b=-16.24429?0.928103). Liver was found to be the best organ for diagnosis of Fowl cholera in broiler breeder flocks.

  This study was conducted to investigate the comparative effect of yogurt as probiotic with the commercially available probiotic protexin on the overall performance of broiler chicks, measured in terms of gain in body weight, feed intake, feed efficiency and economics. One hundred and twenty day old broiler chicks were randomly distributed into 3 main groups A, B and C, that were further divided into 4 sub groups comprising of 10 birds each. Commercial ration was fed ad libitum to all the three groups. The probiotics, yogurt and protexin were given at the rate of 5 mL-1 of water and 1 g L-1 of water to group B and A, respectively while group C was kept as control. The data were statistically analyzed, using Completely Randomized Design. The yogurt resulted in significantly (p<0.05) higher weight gain, feed efficiency, dressing percentage and gross return both in starter as well as finisher phases and Protexin did not affect (p>0.05). Mean FCR value in starter phase was 1.86, 1.69 and 1.84 for groups A, B and C, respectively. Group B showed significantly (p<0.05) improved feed efficiency than other two groups. Mean weight gain in starter phase for group A, B and C was 592.5, 633.8 and 610.0 g, respectively. Group B had significantly higher body weight gain (p<0.05). Feed intake in starter phase was 1104.5, 1076.2 and 1115.7 grams for group A, B and C, respectively, there was no significant difference (p>0.05) in all the three groups. Mean FCR in finisher phase were 2.55, 1.98 and 2.51 for group A, B and C, respectively. Group B showed significantly improved feed efficiency (p<0.05) as compared to other groups. No significant (p>0.05) difference was found in feed intake in finisher phase for groups A, B and C. Feed intake was 3281.075, 3136.37 and 3227.25 g, respectively. Mean weight gain in finisher phase for group A, B and C was 1282.3, 1579.5 and 1280.6 g, respectively. Group B had significantly (p<0.05) higher weight gain than group A and C. The dressing percentage of group B was found highly significant (p<0.05), that was 62.95, 67.82 and 62.89% for group A, B and C, respectively. Mortality was recorded during experimental period. Percent Mortality was 5, 0 and 5% for group A, B and C, respectively. Economics was calculated for feed cost and gross return. Mean feed cost per bird was 70.08, 55.76 and 56.45 rupees for group A, B and C, respectively. Group A, showed significantly higher (p<0.05) feed cost as compared with other groups. Gross return calculated were 93.74, 110.7 and 94.53 rupees for group A, B and C, respectively. Group B had significantly higher gross return (p<0.05) as compared with other groups A and C. It was found that yogurt successfully improved the over all performance and gross return of the experimental birds. Further research is needed to investigate the effect of different levels of yogurt in broilers, layers and breeders.

  Present research was undertaken to investigate the effect of different level of 6% concentrated (w/v) aniseed extract in broiler chicks at NWFP Agricultural University Peshawar Pakistan. One hundred and sixty, day old broiler chicks were randomly assigned to four treatments, as A, B, C, receiving 20, 30 and 40 mL of 6% (w/v) concentrated aniseed infusion and D was kept as control group. Each treatment was replicated four times with ten chicks per replicate. Chicks were reared in cages in an open sided house. Vaccination was done against ND and IBD. Data were recorded for growth performance, immunity and economics. The data were subjected to statistical analysis, using Completely Randomized Design and MSTATC programme. Mean feed and water intake was nonsignificant (p>0.05). Mean weight gain, FCR and dressing percentage was found better (p<0.05) in group C. Mean weight of giblet, intestine, breast, fat and thigh was not altered (p>0.05) in all groups. Mean antibody titer against IBD was higher (p<0.05) in group C and antibody titer against ND and IB was not altered. Mean percent mortality was found higher (p<0.05) in group D. Mean feed cost including the cost of aniseed infusion was not influenced (p>0.05), while the gross return was found better (p<0.05) in group B and C than other groups. Findings of the research study indicated that group C, receiving aniseed infusion at the rate of 40 ml L-1 of water shown better growth performance, immunity and gross return. Detail research work is needed to examine the effect of aniseed in ration and its different form of extracts on poultry production under different environmental conditions.

  The study was conducted to investigate the effect of different levels of feed added black seed (Nigella sativa L.) on the overall performance and immunity of broiler chicks at NWFP Agricultural University, Peshawar in May 2005. Four experimental rations designated as A, B, C and D having black seed at the rate of 0, 20, 30 and 40 g kg‾1 feed were fed to 160 broiler chicks, randomly distributed into 16 replicates, so as to have 4 replicates per group and 10 chicks per replicate. The experiment was lasted for 35 days. Average weight gain, feed consumption, feed efficiency, dressing percentage, weight of different body organs (breast, thigh, intestine), giblets (liver, gizzard), abdominal fat weight, antibody titer against ND, IB and IBD were used as criteria of response. Economics for each group was calculated at the end of experimental period. It was found that group D receiving 40 g kg‾1 of black seed in the feed had a significant (p<0.05) effect on mean body weight gain, feed intake, feed conversion ratio, dressing percentage and weight of different body organs (breast and thigh). Non significant (p>0.05) effect was observed in gizzard, intestine, weight of abdominal fat and feed cost. Antibody titer against ND and IBD were higher in group D, however high antibody titer against IB was recorded in group C. Return per unit of feed cost and gross return were significantly (p<0.05) effected by group D.
