dition of the internal surfaces of milking equipment allows getting the milk with a microbial content of 39.1±3.5 thousand CFU/cm³. After using of the own developed ecologically safe products: alkaline-Sanimol L and acidic-Sanimol K, the bacterial contamination of the internal surfaces of the milking equipment is decreases in 568.1 times (p≤0.001) and averages 0.4±0.1 thousand CFU/cm³. The effectiveness of sanitary processing is 99,8%. And this is allows to get mixed milk with bacterial contamination of 31.7±1.9 thousand CFU/cm³. Mixed milk obtained by using the CircoSuper AF, Sidmax, Sanimol L and Sanimol K at sanitary processing of milking equipment, meet the requirements of EU veterinary-sanitary legislation. The active substances of Sanimol L and Sanimol K released into the soil are degraded to safe components.
The correlation indicators between the results of linear evaluation of first-born cows of two lines - Redad and Horror of Simmental combined breed by type and their milk productivity are given. Animals of both lines are characterized mainly by average values of linear characteristics of the type. At the same time, the highest score is given to first-born cows from the Redad line. There is a direct connection between the direction of the linear evaluation and the milk yield of the first-born from the Redad line in terms of height in the buttocks, depth of the torso, and angularity. Carrying out a linear assessment of the first-born cows of the Simmental combined breed by type allows to identify defects in their exterior, which will further contribute to the effective selection and selection aimed at consolidating herds in accordance with the desired breed characteristics. The growth of Redad cows was estimated at 5.8 points, and of Horror cows - 4.7 points. Animals from the Redad line had a larger chest width (0.6 points, P <0.01), a deep torso. According to the angularity (severity of the milk type), the animals of both lines received an average score (5 points). The depth of the udder is well expressed in the evaluated animals (6.2 and 6.1 points). Animals from the Horror line received the highest score for anterior udder attachment (P<0.05). Animals of both lines are well muscled, they have evenly placed pelvic limbs and strong hooves. The studies showed a positive correlation between milk yield and height in the buttocks, body depth, angularity, anterior attachment of the udder in cows from the Redad line. Negative correlation between milking and central ligament, udder depth, teat length, pelvic limb angle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
