(5) METHOD OF PREPARATION FOR THE RACE OF THE BREEDING RESTRUCTION OF ANNIVERSARY DOG

one

The invention relates to the breeding of animals under cellular conditions and is intended for use in fur farming facilities specialized in breeding raccoon dogs.

The main indicator of zootechnical work in industrial fur farming is the output of puppies per 1 female of the main herd, which largely depends on the sexual activity of animals, their fertility and ability to grow healthy offspring.

The known method of preparing the breeding stock of a raccoon dog is the basis of which is the feeding of breeding animals during the cold period of this period on rations containing from 30 to 980 kcal of exchange energy l.

Also known is the method according to which the breeding stock in the cold season (Part 1 of the period of preparation for the ravine

they are kept in cages with insulated houses; they are supplied with water in the form of ice or snow and are fed according to a diet containing an average of 665 kcal of exchange energy, achieving high fecundity of the females of the living puppy per 1 laboring female} Г21.

However, the biological peculiarity of the organism of raccoon dogs is a decrease in metabolic processes in the cold period by up to 20% compared with the norm,

Therefore, feeding it during this period in a manner known per se causes excessive fat deposition in the body. The animals become lazy, which further negatively affects their reproductive abilities - the percentage of missed females increases, the number of fed puppies decreases, which generally reduces the yield significantly. 3 The purpose of the invention is to reduce the cost of keeping eHotosMflHbix dogs with a simultaneous increase in the reproductive qualities of animals - an increase in the pups' output to the regular ku itself, in other words, a reduction in the cost of fur produced. This goal is achieved by the fact that after coming of constant sub-zero temperatures, pedigree animals undergo fasting for days, and feed them for 700-760 kcal of exchange energy per day, and after the end of fasting for 1015 days - on a diet of 0.5 daily allowance, containing 320-3 0 kcal of exchange energy per head. During fasting, excess body fat and abnormal formations in tissues resulting from a sedentary lifestyle and food overload are utilized in the body. The organism rejuvenates, animals become more mobile, have a vigorous appearance, later on during the rut, they have a higher sex activity than those of fattened animals. In starving females, skipping is less common, pregnancy, whelping and rearing are better. Puppies are born larger, more viable and in large numbers. Experimental data show that among females (19 naked) subjected to a 50-day full food unloading, the percentage of missed was 2 times lower than among females (Il heads) contained by a known method (respectively 32). One and the same maternity who gave birth to a female had the same number of live puppies (6.7 and b, respectively, puppy per female), but the percentage of puppies withdrawal from females subjected to prolonged food unloading was less. Therefore, the yield of puppies in starving females was more than three times higher than that of females, respectively, according to a known method, and 1.1 puppies per female of the main herd (in general, the production performance indicators are lower than known data, but this is due to the quality of the 4th inequality of the current flock, due to the initial stage of the re-raising of the raccoon dog). Example 1. Before fasting, raccoon dogs are fed for food during the month in order to provide for the individual needs of animals in the accumulation of energy resources. At the same time, the amount of feed consumed increases by approximately 1% in comparison with the norm (665 kcal) and amounts to 720 kcal of exchange energy. Then, at the onset of a period of constant sub-zero temperatures, the giving of food is completely stopped within 50 days. The termination of feeding causes animals to bed in winter sleep. 8 conditions of animal farming ((characterized by the presence of uncaught factors). Sleeps do not fall into deep sleep and often come out of crowns. However, this does not negatively affect the animals' well-being, their sexual activity and vitality in subsequent production periods. Best results obtained with a fasting time of 50 days compared with other periods of hunger. Fasting is completed before the rut or at the beginning of the rut period and during the first 15 days after its termination they are fed with animals according to a diet of 0.5 daily norms They contain 330 kcal of metabolizable energy, which provides for the gradual habituation of the organism to food intake and provides additional opportunities for reducing the cost of keeping animals. The feed used in the diet of raccoon dogs contained from 8 to 11 g of digestible protein per 100 kcal of exchange energy. Example 2: The group of raccoon dogs was observed. Three experienced groups of animals were completely devoid of food; 1 group 35 days, from December 16 to January 19, 2nd group 50 days, from December 1 to January 19; - 3rd group 60 days, from 20 November to 19 January.
