The aim of this study was to determine the effect of two mineral-vitamin premixes on the health status (blood biochemical parameters), milk yield and composition of Holstein-Friesian (HF) cows in Kazakhstan. The study was performed on Holstein-Friesian cows kept on the Bek Plus dairy farm in the village of Korzhynkol, Fyodorovsky District, Kostanay Region. Forty primiparous cows, selected from the herd, were divided by the analogue method into two groups: a control group (C) and an experimental group (E) of 20 animals each. The diets fed to group E cows were supplemented with LI-R 18 PRO and PANTO Mineral R-77 Premium mineral-vitamin premixes. The premixes positively affected cow productivity and blood biochemical parameters, whose values were higher in group E than in group C. Higher levels of glucose, albumins and globulins exerted a beneficial influence on the health status of cows. No cases of lameness or metabolic diseases were recorded in group E. The yields of milk, protein and fat were higher in group E than in group C. Dietary supplementation with two premixes had no significant effect on the chemical composition of milk, including the values of the following parameters: somatic cell count (SCC), dry matter (DM), lactose (), casein (), acidity (), lactic acid (LA), density (, free fatty acids (FFAs), glucose () and urea ().
本研究的目的是确定两种矿物质-维生素预混料对哈萨克斯坦荷斯坦-弗里生（HF）奶牛健康状况（血液生化参数）、产奶量及乳成分的影响。研究在科斯塔奈州费奥多罗夫斯基区科尔日恩科尔村的贝克普拉斯奶牛场饲养的荷斯坦-弗里生奶牛上进行。从牛群中挑选出40头初产奶牛，采用类比法将其分为两组：对照组（C）和实验组（E），每组各20头动物。给E组奶牛的日粮补充了LI-R 18 PRO和泛托矿物质R-77优质矿物质-维生素预混料。这些预混料对奶牛生产力和血液生化参数产生了积极影响，E组这些参数的值高于C组。较高水平的葡萄糖、白蛋白和球蛋白对奶牛的健康状况产生了有益影响。E组未记录到跛行或代谢疾病病例。E组的牛奶、蛋白质和脂肪产量高于C组。用两种预混料进行日粮补充对牛奶的化学成分没有显著影响，包括以下参数的值：体细胞计数（SCC）、干物质（DM）、乳糖（）、酪蛋白（）、酸度（）、乳酸（LA）、密度（）、游离脂肪酸（FFA）、葡萄糖（）和尿素（）。
