The current investigation was undertaken with the aim of studying the effect of breed of the animal on various physico-chemical, compositional and microbiological characteristics of bovine colostrum. While studying the effect of breed of the animal on various physico-chemical, compositional and microbiological characteristics of colostrum, it was found that the specific gravity, fat, total protein, casein protein, whey proteins, Lactose, total solids and solids not fat of the colostrum samples from local non-descript animals were significantly (p < 0.05) lower compared to all other animal sources (breeds) under study. The fat content of Jersey cross (fi) [Jersey cross under field conditions] was significantly (p < 0.05) higher than Jersey cross (fa) [Jersey cross under farm conditions]. Total protein content of Jersey and Jersey cross (fi) were found to be comparable however both these samples were found to be possessing significantly (p < 0.05) higher values than Jersey cross (fa). Casein protein of Jersey and Jersey cross (fi) was found to be comparable however both these samples were found to be possessing significantly (p < 0.05) higher values than Jersey cross (fa). Lactose content of Jersey was significantly (p < 0.05) higher than Jersey cross (fi). Total solids content of Jersey cross (fi) was significantly (p < 0.05) higher than Jersey cross (fa). Jersey cross (fi) possessed significantly (p < 0.05) higher solids not fat content than Jersey cross (fa) and the values were found to be comparable with Jersey colostrum samples. The pH values of colostrum samples of Jersey were seen to be significantly (p < 0.05) higher than all other sources of colostrum viz Local, Jersey cross (fa) and Jersey cross (fi). Amongst the latter three, the values were found to be comparable. The ash, electrical conductivity and total plate count (TPC) of the colostrum samples of the animal sources under study were found to be possessing comparable values having no significant (p Gt; 0.05) difference among themselves whatsoever.
