Abstract

It is known that a pregnant sow stays in the farrow machine for 3‒5 days before farrowing, and after ‒ 21‒35 days and more, which necessitates the improvement of keeping conditions. After monitoring the existing easel equipment for farrowing and keeping suckling sows, it was found that the improvement of individual elements of the machines can significantly optimize the physiological and hygienic conditions of their maintenance and increase the comfort level for newborn piglets. Therefore, we have proposed a device for the removable side wall of the machine to increase the space for the sow's exercise, as well as to activate her game behavior with the offspring. The device consists of the following main parts: the upper and lower fastenings of the side wall to the base of the machine, two S-shaped structures made of stainless steel with a diameter of 6 mm. Using the device is possible in two ways.

For optimal access of piglets to the sow’s nipples, it is proposed to increase the floor level for the sow by 1-3 cm. Raising the space under the sow provides piglets with better access to the lower row of nipples, so that piglets are freely located around the sow. And since the place is raised only under the sow, piglets can freely move around the mother’s front and back. The lifting structure is made from hard-alloy plastic or hard rubber 2 cm thick, 60 cm wide and 80-120 cm long. It is fastened to the machine base using self-tapping screws (screws), if the base is plastic or expansion bolts, if the base is made from grating concrete.

Based on the selected individual structural elements of the machines for lactating sows, the improvement of which optimally ensures their biological specifics of keeping, an experimental model of the machine for keeping lactating sows and piglets was made.

Estimation of lactating sows’ productivity, research of some blood indicators and protein metabolism is carried out on the basis of results obtained by the farrowings in the spring-summer period. It was found that keeping sows with offspring in machines with advanced elements increases milk yield, live weight of the nest at weaning, preservation of piglets by 7.3; 9.8 and 1.0 % respectively. The concentration of β- and γ-globulins increases by 0.5 and 0.7 %. At the same time, the content of total protein and albumin decreases by 1.1 g/l and 0.9 %, respectively.
