FIELD: agriculture.
SUBSTANCE: invention relates to agriculture and can be used to optimize cows reproductive functions in conditions of the Magadan Region. Method of cows reproductive function optimization consists in consistently introduction into the main diet of dairy cows after calving of lichens: cladonia alpine (Cladonia alpestris) and Cetraria Icelandic (Cetraria islandica) and sparingly salted salmon as a fodder additive. Lichens were added to the ration daily for the first 60 days of 75 g per head per day. Next 60 days the cows received salted pink salmon every day at a rate of 1 kg per head per day.
EFFECT: invention makes it possible to enrich the diet of animals with protein, enzymes, vitamins, increase adaptogenic properties, improve animals immunity and ensure timely fruitful insemination, which as a result allows to increase the productivity of dairy cows, increase daily milk yields and fat content in milk.
