  A total of 100-day-old broiler chicken were randomly divided into five groups and kept under elevated temperature (95-98.6oF) to observe the effect of potassium chloride and sodium bicarbonate on the weight gain, feed conversion ratio (FCR), serum potassium and serum bicarbonate level. Thermostress lead to significant in decrease (P< 0.05) weight gain, serum potassium and serum bicarbonate level, while FCR was increased. During heat stress, KCl and NaHCO3 at levels of 1.5% and 0.5% respectively, improved weight gain, and FCR and significantly increased (P< 0.05) serum potassium and bicarbonate level. The results showed that combination of KCl and NaHCO3 supplementation alleviated the negative effects of heat stress in broilers.

  A total of 100, day-old broiler chickens were randomly divided into 5 groups and kept under elevated temperature (34-36oC) to see the effect of ascorbic acid and acetylsalicylic acid (Sb-Asper-C, a commercial product) on the feed conversion ratio (FCR), immune status and ratio of weight of bursa, thymus and spleen to body weight. Heat stress increased the FCR but decreased the immune response and ratio of bursa, thymus and spleen to body weight of the birds. Ascorbic acid and acetylsalicylic acid supplementation during heat stress had beneficial effects on FCR, immune status and ratio of weight of bursa, thymus and spleen to body weight of the birds. Grossly, bursa thymus and spleen of heat stressed birds were atrophied but ascorbic acid and acetylsalicylic acid supplemented birds were not atrophied, No specific histopathological changes were observed in all groups.

  The experiment was conducted to find out the effect of birth weight and milk yield on kid mortality in Black Bengal goats from birth to 90 days of age. The results indicated that birth weight of kids and milk yield of does had strong relationship with mortality during the pre-weaning period. Birth weight and milk yield had significant (P<0.05) effect on survivability for all the stages of growth up to 90 and 60 days of age, respectively. The kid survivability were highest and lowest having milk yield of does found to be 400-600 and 80-200 g day‾1, respectively. On the contrary it was also evident that survivability of kids increased from 39.8 to 90.0% with the increase of birth weight from 0.5-0.8 to 2.0-3.0 kg groups, respectively. The same trend of increased survival rate was observed when milk of does increased from 80-200 to 400-600 g day‾1 with corresponding in survival rate from 47.5 to 70.5%. It was concluded that birth weight of kids and milk yield of dam had a pronounced positive effect on kid mortality.

  The present study was carried out for making a keen observation on interphase nuclei of F1s and their respective parents. Mean values for chromocentre number were found to be higher that of their respective Hordeum parents and but lower than that of their Triticum parents. The number of chromocentres were always less compared to their chromosome number in all the F1s. The percentage of heterochromatin per nuclear area in different hybrids ranged from 24.69% (H. nudum x T. durum) to 28.38% (T. aestivum x H.nudum). Nuclear Volume (NV) and Interphase Chromosome Volume (ICV) were found to be proportionally related the number and size of chromosomes. Mean values for Interphase Chromosome Volume (ICV) in the hybrids were found to decrease when compared to Triticum species but increased when compared to Hordeum species.

  The present study was executed for intergeneric crosses reciprocally among four species of Triticum and Hordeum at the first step. Chemical treatment with GA3 yielded better result regarding seed setting. On an average 7.91% seeds were found to set and 68.24% seeds were found to germinate. Most of the hybrid seeds were shriveled, weak, smaller in size, sometimes intermediate and few of them resembled to that of their respective female parent. Seedling viability ranged from 45.45-58.33%. The F1 plants were vegetatively weak and resembled morphologically somewhat to their female parent. The spikes were very weak and the spikelets were found to arrange themselves on the rachis very laxly. All the hybrid plants were found to be sterile in nature.
