| dc.description.abstract | The research work pertaining to “Comparative study of physico-chemical and free fatty acid profile of milk in Gir and its crosses” was undertaken in laboratory of the Department of Animal Husbandry and Dairy Science, M.P.K.V., Rahuri (M.S.). The experiment was conducted during the year 2013-14. The main objective of this study was to assess the physico- chemical parameters, compare the micro and macro mineral content and free fatty acid profile of milk of Gir and its crosses. After finalizing the objectives 12 Gir, 12 of Gir Half-bred (GHB) and 12 of Phule Triveni cows were selected on their 1st (7-30 days), 2nd (31-60 days), 3rd (61-150 days) and 4th (151-270 days) lactation stages from the Research-cum-Development Project, (RCDP) on cattle at M.P.K.V., Rahuri. The mean specific gravity of milk (1.029) was not affected by stage of lactation and breed. It was further noticed that the specific gravity of milk from the 1st to 4th stage of a lactation was same indicating there by that specific gravity did not vary throughout the lactation during the study. It was observed that in Gir, Gir half-bred and Phule Triveni the mean electrical conductivity of the milk was ( 0.378, 0.377 and 0.376 Am v-1m-1) in the 1st stage of lactation which increased with the advancing stage of lactation (0.411, 0.410 and 0.408 Am v-1m-1 ) in the fourth stage. The viscosity of milk was not significantly affected due to breed and its interaction with stage of lactation. The values were at par with each other during different stage of lactation. It was noticed that the fat content for 30 days post partum remained minimum but from the 31st day upto the end of lactation it showed gradual rise upto the advanced stage of lactation. Amongst the breeds highest mean fat content in Gir was 4.24 per cent, 4.17 per cent in Gir half-bred and 4.07 per cent in Phule Triveni. Breed and its interaction with the stage of lactation did not significantly affect the fat content of the milk. The mean lactose content varied in different breeds and also during the different lactation stages. Maximum mean lactose (4.48%) was observed in first stage of lactation which decreased gradually with each stage of lactation. It was noticed that the stage with the stage of lactation had non-significant (P < 0.01) effect on lactose content. of lactation had significant effect, while breed and its interaction | en_US |
