The influence of mineral licking briquette “Amirasol R-Z” on the cows’ protein and hematological blood indicators

The purpose of the research was to study the effect of mineral licking briquette “Amirasol R-Z” on protein and hematological blood parameters of dairy cows. Scientific and experimental study was carried out on the cows of red steppe breed in the conditions of flat zone of Dagestan Republic. Two groups of milk cows were formed (control and experimental), with 10 animals in each. The duration of the experiment was 90 days. According to experimental scheme, control group received the main diet, consisting of crushed mixture of barley and wheat and mixed hay, experimental group received the main diet and mineral licking briquette “Amirasol R-Z”, consisting of table salt and macro- and micronutrient elements. Each experimental cow was individually given one licking briquette during 90 days. The research and data processing was carried out according to generally accepted methods. At the end of the experiment the blood was taken from the jugular vein from experimental animals for carrying out laboratory tests. The milk productivity and fat content of cows’ milk by conducting monthly control milk yields were taken into account. As a result of the studies positive effect of “Amirasol R-Z” licking briquette on hematological parameters, total protein, protein fractions of blood and milk productivity of cows was established. At the same time, there was significant increase in the blood of the cows of experimental group in hemoglobin by 8.65 %, the number of red blood cells - by 10.38 %, the content of total protein in the blood serum - by 10.37 %, albumins - by 6.58 %, γ-globulin fractions - by 12.30 %, dairy efficiency - by 5.7 %, milk fat content - by 3.33 % compared with control group. The received results of scientific researches showed that using mineral licking briquette "Amirasol R-Z" in the diets of dairy cows during three months had contributed to significant increase in hematological parameters, total protein, protein fractions, dairy efficiency and fat content of milk.
