ThesisItem Open Access STRATEGIC MINERAL SUPPLEMENTATION STUDIES ON THE PERFORMANCE OF HEIFERS(CSKHPKV, Palampur, 2009-08) S. Bais, Isha; Sharma, K. B.Unlike other nutrients, mineral elements can not be synthesized by living organisms. Therefore, a minimum level of mineral intake is necessary to fulfill the basic needs of the animals. Thus, investigations were conducted on strategic mineral supplementation in growing heifers to ensure better performance of heifers in their productive life. The heifers of different stages of development were selected and the effect of mineral supplementation on haematological, biochemical, growth and cyclicity was observed. The plasma as well as feed, fodder and water samples were analyzed for mineral status and the mineral mixture was formulated according to the prevalence of mineral deficiency and the animals were supplemented with mineral mixture for three months. Haematological and biochemical parameters varied within the normal range during the supplementation period. Overall significant (p<0.05) reduction in deficiency of calcium, sodium, potassium and copper was upto 47.20, 46.85, 49.36 and 78.93 % in calves, growing heifers and mature heifers respectively. Significant (p<0.05) effect on growth and cyclicity was observed with overall 12 % increase in body weight and 42.88 % of the growing and mature heifers showed signs of estrous. Mineral analysis of feed and fodder samples showed optimum levels except for copper which was quite low. It has been revealed from the study that correlation exists between mineral status of feed, fodder, water offered and blood plasma of the animals. On the basis of present study, it is concluded that a sufficient amount of mineral nutrients has to be supplemented to achieve optimum growth and performance of different stages of development in heifers of this area of Himachal Pradesh.ThesisItem Open Access INVESTIGATION ON DIETARY AND ENVIRONMENTAL COMPONENTS VIS-À-VIS SKIN HEALTH IN DOGS(CSKHPKV, Palampur, 2008) Gupta, Ankur; Mandial, R.K.
