Productivity of Simmentals Livestock of Austrian Breeding in Climatic Conditions of the Karachay- Cherkess Republic
International Journal of Engineering and Advanced Technology
The aim of the work was to establish the adaptive abilities and milk productivity of Simmental cows of Austrian origin in the conditions of the Karachay-Cherkess Republic. Research and production experience was held at Hammer Company LLC, Prikubansky District, Karachay-Cherkess Republic, in which 400 head Simmental heifers were brought from Austria. For the experiment, 40 cows of Schwyz and Simmental breeds were selected. Schwyz cows were included in the experiment (control group I), as well
... pted to the conditions of Karachay-Cherkessia, and Simmental cows constituted the second experimental group. Among Simmental cows with a bath-like form of the udder, it was 12.5%, while in Swiss peers - 2.5%, with a bowl-shaped form - 60.0%, and in peers - 47.5%, Schwyz cows were in the lead - 50%, for Simmental - 27.5%. There were no significant differences between the groups of experimental cows in hemoglobin, erythrocyte, and leukocyte counts. On average, the hemoglobin level in the rocks was within the normal range and was 109.8-110.1g / l, the content of erythrocytes was 7.2-7.4x1012 / l, and leukocytes were 9.9-10.2x109 / l. The heart rate and respiration rate in adapting Simmental cows were slightly higher than in their peers of the Swiss breed and were 71.8-73.5; 24.7-26.8 times per minute and 70.5-71.0; 23.4-24.2 times per minute, respectively. The highest milk production in the second lactation was distinguished by Simmental cows, their milk yield was 4455 kg of milk, which is 958 kg or 27.4% higher than the Swiss peers. The fat content of milk in Simmental cows was at the level of 3.84%, protein 3.32%. The superiority of Simmental cows over Swiss peers in terms of fat and protein content in milk was 0.11% and 0.15%, respectively. Simmental cows in the new climatic conditions provided an increase in milk productivity, which indicates good lability of the organism in the new geographical area.
