An efficient mineral and energy supplement in the rations of highly productive cows

The article discusses the results of scientific and economic experiment carried out on black-motley breed cows on the use of mineral and energy supplement, ‘Reactor’, which includes energy components, calcium propionate, betaine and natural sorbent. The complex action of the investigated product had a positive impact on animal productivity. It was established experimentally that using during the transitional period of 250-350 gr. of ‘Reactor’ per head daily allows to increase daily milk yield of cows in the first hundred days of lactation by 9.8 and 14.5% (to 30.3 and 31.6 kg vs.

Effective additive «Tasco» in the diets of Ayrshire cows

Research on studies of feed additive Tasco, consisting of 96% dried seaweeds, influence on the amount and composition of milk in microelements and in iodine specification as well as reproductive characteristics performed by high-yielding cows are carried out. It is established that the studied product inclusion into cows’ rations by 40 and 60 gr a day per head allowed increase day yields from 29,5 kg to 31,7 and 32,8 kg (by 7,5 and 11,2%) in the first lactation period. The tendency of positive Tasco influence on cows’ reproduction is determined as service-period duration is decreased.
