SU1664205A1 - Method for making up technological groups of milking cows - Google Patents

Abstract

The invention relates to animal husbandry. The purpose of the invention is to increase milk production, reduce the aggressiveness and injury of cows. Technological groups of lactating cows are formed after calving, taking into account the behavioral structure of the herd as spontaneously occurring cohesial communities. The division into groups is carried out by visual observation of the behavior of animals at rest, during feeding and milking. Of cows that differ in the consistency of actions: they are located in a separate group, rest lying down, not aggressive to each other, form one group. In the other group they concentrate animals that are not accepted into cohesive communities: they hold one by one, rest a hundred, feed the latter. Acquisition of groups, taking into account cohesive communities, accelerates the establishment of hierarchical hierarchy between animals after their regrouping, reduces their injuries, increases the milk productivity of cows.

Description

The invention relates to animal husbandry and can be used to improve the technology of keeping cows on dairy complexes.

The purpose of the invention is to increase milk production, reduce the aggressiveness and injury of cows.

PRI me R. On a complex with a free-boxed animals, 134 new cows are selected. During the equalization period (30 days), animals of the experimental and control groups are kept together in communities with hierarchical subordination. Then from the experimental group on

Based on visual observations of cows' behavior, the following subgroups are distinguished:

1A - animals united in cohesive communities, characterized by the desire to hold together, synchronously eat food, rest in a separate group, among them there is no competition or priority when feeding and milking;

1 B - single animals that are not accepted in formed friendly communities, they consume fodder longer and last of all, rest away from communities, more often a hundred. In a single subgroup of single cows there is no aggression against one another.

The control group was divided into two subgroups, 2 A and 2 B, which combined the animals according to hierarchical subordination.

After the formation of technological groups, taking into account the behavioral structure of the herd, the average daily milk yield of animals from cohesial communities (subgroup 1 A) and single animals (subgroup 1 B) exceeded by 11.8 and 3.9% of the milk yield of animals of the control subgroups 2 A and 2 B The formation of technological groups of cows without taking into account the spontaneously formed cohesive communities (subgroups 2 A and 2 B) increases by 3.6 and 3.3 times the number of duels between the cows. Aggression between animals exceeds their total motor activity 1.7 times. Animals from subgroups 1A and 1B, formed taking into account the behavioral structure of the herd, are much calmer. The rang wrestling among them is almost absent. No injuries.

Indicators of the behavioral structure of the herd and the productivity of cows are shown in the table.

Using the proposed method of forming groups of cows reduces the stress situation in animals and feed consumption by 21.4% and 15.2% and at the same time has a positive effect on the milk productivity of the cows.

Claims (1)

The invention of the method of forming technological groups of lactating cows, including the distribution of animals, taking into account the behavioral structure of the herd, characterized in that in order to increase milk productivity, reduce aggressiveness and injury to cows, animals are distributed into groups, taking into account the behavioral structure of the herd as spontaneously arising cohesive communities by visual observation of the behavior of cows during milking, feeding and resting, with one group being formed from cows synchronously eating to rm going to milking and holidaymakers separate community without aggression to each other, and the other - from single cows which are not included in kogezial- nye community
