EFFECT: improved animal health. 2 cl

Description

 The invention relates to agriculture and can be used in fur farming in order to increase the reproductive ability of female fur-bearing animal animals.

 According to research and analysis of the economic activities of farms of various systems and departments, it is known that significant puppy losses occur in the second half of pregnancy in minks and on day 19-20 in canine family animals (resorption, dysfunctional births), as well as in the first days after birth (death of weak puppies).

 It was suggested that these anomalies are associated with violations of the trophic system of the placenta, the inadequate supply of its blood, and hence the unsatisfactory supply of some of the embryos with nutrients and oxygen.

 Since the main object of cell farming is mink, experiments were carried out on this type of fur animals.

 In the experiments, a whole complex of drugs was used to improve placental metabolism.

 To ensure maximum animal identity in the experiment and control, to eliminate the influence of keeping factors in the qualification of animal breeders, preparations are given in the feed for half of the females of each litter - the second half serves as control.

 The aim of the invention is to increase the reproductive ability of females and reduce the early departure of puppies.

 This goal is achieved by the fact that from the day of implantation to whelping, pregnant females are supplemented with dibazole, aspirin, papaverine and trental dissolved in water daily in doses: 0.1-0.2 mg, 2-3 mg, 0.5 mg and 1 , 5 mg, respectively, per 1 kg of live weight of the animal. Depending on the consistency of the feed, the required amount of water can be added to it for better mixing of the feed mixture. Feeding is carried out according to the scheme: one day dibazol, aspirin and papaverine; the next is trental.

 The prototype is the usual standard diet used in animal husbandry.

 Studies to identify the possibility of increasing the reproductive ability of female minks and reducing the early departure of puppies in the first days of life were carried out in the Saltykovsky fur farms of the Moscow Region and the Kaalamsky Karelian Autonomous Soviet Socialist Republic, as well as in the Cherkassky fur farm of the Cherkasy OPS.

 PRI me R. Studies were conducted in a number of farms in various climatic regions of the country.

 For 200 females of the main herd of mink, these components were given in a quantitative ratio of 1: 2: 4: 4.

 This number of animals is just half of the generosity, the second served as control.

 The optimal ratio of components and the amount of each of them are determined on the basis of indicators of average live weight of female mink during pregnancy, as well as taking into account existing physiological norms of dosages, these drugs per 1 kg g.v.

 Smaller dosages of these components are not sufficient to obtain a positive effect, large ones can lead to undesirable consequences (abortion, resorption of some embryos).

 The order of preparation of the mixture is as follows: the components previously ground to a powder state are dissolved in 100 ml of distilled or boiled water and added to the finished feed mixture. Depending on the consistency of the feed, the volume of water may vary. Feeding is carried out the entire period of pregnancy before whelping of females (30-40 days).

 In 1991, the proposed method passed extensive production testing at the Kalaamsky fur farm of the Karelian Autonomous Soviet Socialist Republic.

 In the experience there were over 7 thousand females.

 Due to the development, more than 2 thousand young mink were obtained.
