Pigs warm in winter and reform measures in the construction of the circle

Winter, cold weather, use warm circle pig \moisture dewetting a good way to increase the pig is also effective, to adapt to the development of pig production, pig-effective new technologies to improve. I. Nuanshi pig pigs are the advantages of animal temperature, and only in the appropriate temperature conditions to normal growth, development, production to its full potential, reach survival, faster growth, more weight, less material consumption, increase efficiency purposes. pigs suitable temperature is: 1. newborn piglets: 1 ~ 5 days, 32 ~ 30 ℃; 6 ~ 10 days, 30 ~ 28 ℃; 11 ~ 14 days, 30 ~ 25 ℃; 15 ~ 30 days, 25 ~ 22 ℃. 2. fattening pigs: 20 ~ 60 kg, 21 ~ 22 ℃; 61 ~ 100 公斤, 18 ~ 20 ℃. If the temperature is lower than the optimum temperature for pens, newborn piglets at 1 ℃ temperature conditions, 2 hours after the cold dusk, frozen, freezing to death or squeezing each other death; in 13 ~ 24 ℃ temperature conditions, 1 hour after birth, the body temperature could be reduced 1.7 ~ 7 ℃. in less than optimum conditions of temperature, the temperature of each drop pens 1 ℃, 2 piglets per head per day Multi-day consumption of milk and 22 grams, 7 days old piglet milk consumption per head per day more than 120 grams; growing finishing pigs per head per day less weight 17.8 g, feed consumption per kilogram of weight gain more than 25 to 30 grams. the temperature dropped to 4 ℃, 50% of the weight gain slowed down or even halt weight gain, feed consumption per kilogram of weight gain more than 2 times. From the above analysis of the situation, the low temperature in the cold season to improve the survival rate of piglets,[link widoczny dla zalogowanych], fast growth, more weight gain , less material consumption, increase efficiency, must be taken to the warm circle pig technology. Second, the construction and transformation of the warm circle of the warm circle of the construction and transformation, to local conditions, local materials, commonly used in the construction and transformation of the warm circle is: 1, G the construction of the warm circle. In north to south or north of high slope, cliffs, walls, buildings, etc. at the leeward sunny, digging deep revision 1.5 to 2 meters, rectangular (length, width depending on the number of pigs) pit, bottom floor from north to south, divided north and south twice, the North than the South ring ring 0.3 to 0.5 meters, the hole surrounded by a solid brick or stone, in the south wall to be able to open at the left of a row related to fecal vent. circle the northern wall of the wall, above the ground should be appropriate, so that the wall was 45 ° north and south slope of the second. In the second north-south wall, every 30 to 40 cm diameter, take a 4 to 5 cm, straight and smooth, each parallel to the wood, wood strips, the rod of high strength plastic film cover. In the film with 2 to 3 cm in diameter, wood and wood under the membrane firmly clamping the membrane,[link widoczny dla zalogowanych], surrounded by Mud will not firmly tighten the seal on the wall. In a switch conveniently located southeast corner of the plastic door tight to the breeder and out of feeding and management. 2, floor heating loop alterations. alterations following two methods. ⑴ slope shape plastic film to circle. In the open side of the circle on the wall, make bricks from north to south, was 45 ° slope, until the roof of the wall, the wall under the warm circle wildly like the tightly sealed with plastic film, also set a Start or defecation mouth. ⑵ to curved plastic stalls for homes. with a diameter of 3 to 4 cm thick, 4 ~ 5 cm (the distance between sheds and concrete to the height of the roof may be) of the pole bent arc (center top of the arc to pole in parallel with eaves date), two into the wall on both sides; from under the eaves of the wall began to ring every 20 to 30 centimeters still a parallel bar, parallel to each other up and down about it; and then started from the pole top center,[link widoczny dla zalogowanych], from north to south, bamboo or wood with a straight vertical pole connected with the top of the arc, in its aspect at the junction of the two tightly with wire tie together. Thus, in the middle on both sides, every 20 to 30 centimeters still a parallel ligation. In the above, based on the high-strength plastic film sealed in the top, smoothing tension in the membrane phase with the wall at the seal with the Mud, and then the wall on both sides of the ring every 20 ~ 30 cm Equal nail nails will be thin nylon string pressure in the arc surface tension after the two tied in the nail to prevent the film was the wind off. ⑶ change without windows and doors have windows for the pig barn. in the pig house windows and doors, the placement of plastic film or glass sealed windows and doors, sunny place on the roof, re-established sealed with plastic film or glass skylights to light the ground surjective pig subject. ⑷ additional suites, nursing Aberdeen bar,[link widoczny dla zalogowanych], an incubator. open circle in the corner, both set a temperature, but also preservation of the suite, so that sows farrowing in the suite, room and board in which piglets; or additional brick masonry retaining Aberdeen bar, wooden incubator, built a dry, soft bedding or heating facilities for food and accommodation in the bar inside the piglets, the use of heating facilities, temperature, the use of the heat insulation own piglets. 3, the construction of semi-underground heating cycle. semi-underground construction of the warm circle In addition sheds half of the wall exposed to the ground, and at the installation in the sunny windows sealed with plastic film, the other with the underground construction of the warm circle of the same. 4, modification plus a warm lap. Based on the above sheds , or in caves, tunnels pig, the addition of underground flue withdrawn from circulation, warm wall of fire, soil heating, install infrared lights, infrared heating panels, electric heating, insulation umbrella warming facilities for fuel or electricity used to make pens within temperature reaches optimum temperature.
