INFLUENCE OF COW WATERING TECHNOLOGY ON RUMINATOR PROCESSES AND DAIRY PRODUCTIVITY

چکیده
The results of studies on changing the technology drinking for dairy cows by installing an additional trough-type drinker route from milking parlor to main housing are presented. For this, a scientific and economic experiment was carried out according method groups periods 65 second third lactation. It found that 2–3 days after installation watering, began linger near watering devices quickly consumed running water during first 0.5 minutes. As result, concentration bowls in cow house visually reduced. Changes cows' patterns led increase dry matter consumption diet 5.3 % gradual frequency cicatricial contractions. change provided average daily milk yield 1.03 kg or 4.79 %. In addition, there has been tendency towards percentage protein milk. Improvement supply body due changes contributed microbiological purity milk, which reflected decrease bacterial seed production 305.3 297.9 thousand / cm3. return standard principle productivity indicators their original level. Therefore, it can be argued about advisability using selected technological drinking.

Anatomical and functional characteristics of the teat are supposed to have considerableinfluence on milk flow performance. In the present study various teat and milkingcharacteristics in 148 quarters of 38 cows were analyzed via 3 different approaches. Teatcanal length, teat wall thickness and teat diameter were measured by ultrasound. In addition,the vacuum needed to open the t...

To explore how hoof pathologies affect the gait of dairy cattle, we studied gait profiles of cows with no visible injuries (n = 17), sole lesions (n = 14), and sole ulcers (n = 7). Video recordings of dairy cows were digitized using motion analysis software to calculate 6 stride variables for each hoof. Compared with cows with sole ulcers, healthy cows walked faster (1.11 +/- 0.03 vs. 0.90 +/- ...
متن کاملIdentification of Immune Traits Correlated with Dairy Cow Health, Reproduction and Productivity
Detailed biological analyses (e.g. epidemiological, genetic) of animal health and fitness in the field are limited by the lack of large-scale recording of individual animals. An alternative approach is to identify immune traits that are associated with these important functions and can be subsequently used in more detailed studies. We have used an experimental dairy herd with uniquely dense phe...
