Study on Body Condition Score and its Relationship with Solid Not Fat and Weekly Fat Corrected Milk Yield in Frieswal Cows
Abstract:
The study was carried out at Military Dairy Farm on Eighty milch Frieswal cows. The cows were divided in five parities and three stages of lactation. The study was done for Body Condition Score and its relation with production parameters namely solid not fat percent and weekly fat corrected milk yield (3.5%) along with the effect of parities and stages of lactation on Body Condition Score, production parameters. The Body Condition Score (BCS) system is a subjective scoring method of evaluating the energy reserve of dairy animal to provide better understanding of biological relationships between body fat, milk production parameters. The overall least square mean of body condition score related to parity as well as stage of lactation was 3.35±0.04. The effect of parity was found significant on body condition score and solid not fat percent and weekly fat corrected milk yield while stage of lactation showed significant effect on body condition score and solid not fat percent. The stage of lactation did not showed significant effect on weekly fat corrected milk yield. The significant correlation and regression of body condition score was not seen with solid not fat and weekly fat corrected milk yield. This can be concluded that parity and stage of lactation have positive and significant impact on milk production parameters.
