Abstract:

The present study was carried out on 07 Sahiwal lactating cows, which were kept under standard feed and managerial conditions during the experimental period in complete lactation. The milk composition was determined by automatic milk analyzer for fat, protein, lactose and SNF and milk yield was recorded for each sampling day. Somatic cells counts (SCC) was enumerated by standard method and BCS was recorded at fortnightly interval of all the experimental animals. The blood samples were collected on 7th day after parturition and thereafter at fortnightly intervals till complete lactation from each animals and the serum was separated out and kept in aliquots for estimation of hormones, metabolites and biochemical parameters. The blood glucose concentration was immediately determined in fresh blood. The profile of metabolic hormones viz. T3, T4, Insulin and GH, blood metabolites viz. blood glucose and NEFA and the biochemical profile viz. calcium, phosphorus and magnesium were determined during various stages of lactation. The average Lactation length was 294.71 ± 5.23 in Sahiwal cows. There was highly significant (P<0.01) difference in MY, Fat, BCS, T3, T4, Insulin, GH, Glucose, Ca, P and Mg concentration and significant (P<0.05) difference in SCC and NEFA concentration during various days of sampling during complete lactation in Sahiwal cows. However, there was non significant observed in Protein, Lactose and SNF % during various days of sampling during complete lactation in Sahiwal cows. The relationship of these hormones, metabolites and biochemical parameters will help to understand the role of each of them in modulating the complete lactation of cows.
