This study was conducted in AL-Ishaqi Cattle Station, north of Baghdad and use of 36 multiparous Friesian cows in the early lactation, cows were assigned randomly into three main groups, includes all cows. They were received a basal diet and 0 niacin (group 1), 6 g niacin (group 2) 12 g niacin (group 3) of supplementation niacin per day over 22 week experimental period to study the effect of niacin supplementation on average of weekly milk production and level of &beta -Hydoxybutyrate (BHBA), acetone, triglycerides, glucose and glucagon hormone in blood. The results showed a highly significant effect of niacin supplementation level 6 and 12 g in increase of weekly milk production for the months of June, July and August, also reduce the level of &beta -Hydoxybutyrate (BHBA), acetone, triglycerides compared to the control group, rate this amounted materials for two levels respectively 0.449±0.029 (mmol/L), 11.00±0.89 and 16.16±1.76 (mg/dL) and 0.237±0.013 (mmol/L) and 6.16±0.47 and 13.39±1.49 (mg/dL) compared to the control group for the first month of the study, this influence continued for the subsequent two months, well as the effect of niacin levels mentioned above significantly (p<0.01) in high blood glucose levels and glucagon hormone. Appears the niacin has improved energy use for cows postpartum, so reduced the indicators of metabolic diseases which usually infect cows in the beginning of the lactation period such as disease of ketosis.
Key words: &beta-hydoxybutyrate, dairy, cow, ketosis, niacin, ,
