Economic efficiency of application in the diet of red foxes succinic acid

The results of the conducted scientific and commercial experiments on the development of technology of cultivation of red foxes "moth Vyatka" with the use of succinic acid gave the basis for testing research in industry. The improved technology of the content of reproductive females comprised the addition to the feed the succinic acid at a dose of 10 mg per kg of body weight, a month before the rut, making every five days, two day break. Waste the unborn young from the females contained on superior technology amounted to 0,10 0,22 puppy against puppy in the control (p<0.05), number of pups per female owenissalty at the time jigging made up 5.10 4.87 V against control (p<0.05), respectively. The economic effect of the sale of puppies 1 female, amounted to RUB 1399,50. Data indicate a rather high efficiency of use of the females of succinic acid in the period of reproduction. Trademark young the drug was added to the feed since the depositing rate of 5 mg per kg bodyweight, two or five day course with a two day break, at the beginning of each month for five before slaughter. The average area of the skins of foxes grown using superior technology in comparison with the control significantly (p<0.05) were greater at 0, 25 dm2 males, females - 0.30 dm2. Credit quality was significantly (p<0.05) higher in animals treated by succinic acid, 2.5% in males and females. Economic effect of the implementation of one of the skins from males amounted to RUB 95,39, females - 76,43 RUB. The Calculation of economic effect from the use of advanced technology of cultivation of red foxes showed the possibility of obtaining additional profit fur farms.
