Effects of utilizing rumen protected niacin on core body temperature as well as milk production and composition in lactating dairy cows during heat stress
RB Zimbelman, RJ Collier, TR Bilby - Animal feed science and technology, 2013 - Elsevier
Niacin has been shown to increase resistance to thermal stress in cattle by increasing
evaporative heat loss in vivo and cellular heat shock response by increasing gene
expression of heat shock proteins 27 and 70 during thermal stress in vitro. To determine
effects of feeding encapsulated niacin on vaginal temperature, milk yield and composition, a
total of 198 primiparous and 229 multiparous lactating Holstein cows were randomly
assigned in a crossover design to either control (no niacin additive, n= 213) or niacin (NIA; …
