The milk production capacity of Kankrej cattle and Mehsana buffaloes herd at Livestock Research Station was compared from the year 2010 to 2013 to know the influence of season on production of herd and to find out the superior herd of them. The herd average of Kankrej cattle remains significantly higher throughout the year especially in summer season in comparison to Mehsana buffalo. [ABSTRACT FROM AUTHOR]

The influence of non-genetic factors namely breed, sex, age, season and cause of death on the mortality of rabbits were studied utilizing a total of 835 mortality records over a period of 20 years. The study revealed that there is a significant difference (P<0.05) in number of pre-weaning mortalities between seasons, with more mortality in summer and least in winter season. The preweaning mortality observed in Soviet Chinchilla in summer, south-west monsoon, north-west monsoon and winter seasons were 29.53, 28.37, 27.60 and 14.48 per cent, respectively and the values observed in White Giant were 32.80, 27.12, 32.49 and 7.57 per cent, respectively. The postweaning mortality did not differ significantly between breeds, sexes and seasons. The cause of death did not influence the number of mortality between four seasons of the year. However, pneumonia and enteritis resulted in more mortalities than other causes. [ABSTRACT FROM AUTHOR]

A study was carried out to assess the influence of summer stress and effect of supplementation of vitamin E and selenium during different season on serum enzyme activities, i.e., aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in Hallikar cattle. In the control group, activities of AST, ALT and ALP were significantly (P<0.05) higher during the summer season compared to winter season and rainy season. Further, the activity of all the enzymes were significantly (P<0.05) reduced in supplemented group compared to control group during summer, winter and rainy season. [ABSTRACT FROM AUTHOR]
