Because of its advantages such as convenient management, reduction of crushing and death of pigs, and ease of feeding in and out, the limited bed has been widely used in large-scale pig farms in China. However, a problem that has existed for many years has not been solved well. It is a duck-billed drinking fountain that is commonly installed on the production bed. When the sow bite drinks, it will inevitably lead to water leakage and splashing, often resulting in a front bed of the delivery bed. In wet conditions, the sow's head, neck, and forequarters are splashed wet, especially if the sow’s body is splashed wet, causing a series of adverse consequences (winter has more of an effect on the pig); besides, drinking water Over- and under-installation of the instrument and low water pressure all affect the sow’s intake of water, which in turn affects the sow’s health and lactation levels. The potential for modern genotype sows’ production performance increases, but low feed intake during lactation is always a Not a small problem, poor drinking water exacerbates food intake, and its negative consequences increase. In view of the above problems, the author has designed the equipment for water tanks with the same tanks. After nearly 4 years of application, it proved to be a simple and easy-to-follow measure to solve practical production problems.
Prefabricated hemispherical water chutes for equipment and installations. The trough height is 40 centimeters, the trough wall thickness is 3 centimeters, the slot mouth is elliptical (25 centimeters and 22 centimeters), and the trough mouth uses the inward and inward plano convexity 1.5 centimeters to prevent the water material from being carried out when feeding. The drinking fountain is erected directly in front of the inner wall of the tank, 5 centimeters from the bottom of the tank. The tank is tilted 10 to the feed end.
Application and observation After years of practice, the following methods are recommended. The dry powder is directly placed into the tank according to the operating procedures and the sows are selected according to their own preference. A few of the sows directly feed the dry powder; most of them use the snout to cope with the drinking water and then reconcile the dry powder into a moist material. After eating porridge material. When drinking water alone, the sow will use the snout to reach the drinking fountain. After the water flows into the bottom of the trough, it will be consumed by natural drinking water (the pig will use the water fountain directly to indirectly use the water fountain to drink water in the trough, only 1 day ~2 days is the habit.
After using the water tank with the same equipment in the bed, the sow water intake, when the intake of a few anhydrous material extravasation, to keep the bed dry, is particularly conducive to the health of the mother and child; the child pigs without splashes of pain, reducing the incidence of pigs The possibility of colds and diarrhoea (especially in winter); self-reconciliation of the feed water in the tank increases the feed intake of the sow, especially in the hot summer, more than 0.5 kg per day can be eaten more than a conventional food tank. Contribute to the increase of milk secretion; After the natural drinking method is adopted, the sow can maintain a sufficient amount of drinking water, is not limited by the flow rate of the drinker or improper installation, and can fully meet the high yield due to factors such as lactation output. Lactating physiological requirements for sows during lactation
