Feeding management of piglets in nursery homes
Piglets are the basis for pig production, and they are the key to the development of quantity, quality, and production costs. Nursery pigs refer to piglets reared in nurseries after weaning, that is, from the time when they leave the maternity ward until they move out of the nursery to become commercial piglets, which are generally between the ages of 28 and 70 days. The purpose of raising nursery piglets is to provide more. Finishing pigs and breeding pigs. However, the nursery piglets are faced with two stresses of weaning and transfer. Therefore, the feeding and management of the nursery piglets becomes very difficult. Therefore, only by grasping the physiological characteristics and growth patterns of the nursery piglets and taking corresponding measures can the breeding be improved. rate.
1. Prepare the piglet for the work before entering the house The piglet must be carefully cleaned and disinfected to ensure cleanliness before the piglet enters the house. After the last batch of piglets turn away, rinse the interior clean, especially at the dead corner. Rinse well to repair the damaged barn equipment, check whether the water line is unblocked, etc., then start disinfecting and fumigation. Use ordinary disinfectant to eliminate the poison first. , Fumigation with formaldehyde for another 24-48 hours, to be sprayed before disinfection.
2. Good environmental hygiene Dry nurseries and good hygiene are necessary factors for the survival of piglets. The reproduction of microorganisms is faster in humid environments; the loss of body temperature in nursery piglets severely restricts the growth and development of piglets. In addition, the health status of the nursery is also very important. In general health nurseries, daily intake of piglets was 0.81 kg, and the daily gain was 0.47 kg, and the ratio of feed to meat was 1.72:1. The nursery with better sanitary conditions had a daily feed intake of 0.87 kg. The weight gain was 0,67 kg and the feed to meat ratio was 1.298:1.
3. Sufficient space for conservation Shelter bed area must allow the pig to have enough space before leaving the bed. That is, 10-20 kg of pigs only 0.2 square meters; 20-25 kg of pigs only 0.3 square meters.
4, the appropriate temperature and humidity 4.1 Temperature as a basic condition for the survival of piglets is very important, the increase in environmental temperature is conducive to improve the resistance of piglets and improve feed utilization. In general, the required temperature for pigs of a specific weight varies with the external environment such as feed intake, number of cousins, and ventilation. Pigs that have just been weaned into the nursery will have a temperature of around 27°C and will be cooled 1°C-2°C each week thereafter. When the piglet weighs 20 kg, the temperature will only be about 20 degrees. Second, you can also observe the lying of the pig to estimate its comfort. 4.2 Humidity: The most suitable relative humidity for conservation is 65% - 75%. The temperature and hygrometer should be installed in the house and the indoor temperature and humidity should be known at any time.
5, scientific feeding management. 5.1 It is critical that nursery piglets that have been weaned enter the nursery net bed for 7-10 days. This period is the peak of the digestive tract and respiratory diseases occurring in the nursery piglets. Piglets fed this period must be able to: (1) allow the piglets to pick up and eat as quickly as possible so that the piglets receive adequate nutrition; (2) the diet of the piglets must be nutritionally balanced, with less feeding added and keeping the feed fresh. 3 to prevent overeating, not to restrict feeding. The daily feed intake of 28-42 days old piglets is generally 0.22-0.56kg; the daily feed intake of 42-60 days old piglets: 0.56-0.88kg; the feed intake of 60-70 days old piglets: 0.88-1.2kg. 5.2 The nursery piglet enters the nursery for 10 days and begins to enter a vigorous diet. At this time, the piglets should be allowed to feed freely and do not limit the feed intake. And require the quality of the feed is better, should feed high protein, high energy, high digestibility feed. To ensure the feed, we must also ensure that the piglets have sufficient and clean drinking water. 5.3 During the childcare period, some piglets will have individual weak piglets. These piglets are often undetected and ultimately form dead pigs or die. What is more dangerous is that these weak piglets are also the source of infection. They should be promptly removed and fed separately to promote the health of the weak piglets as soon as possible.
6. Make a good record of conservation, regularly observe the pigs in the feeding and management but also regularly make good nursery records, carefully record the situation of feeding piglets every day, mainly record the number of feedings on the day, feeding the varieties of feed, Dosage and so on, but also to carefully record the prevention and control of the epidemic in the feeding and management process. The main roles of conservation records are: 1 It helps with the accounting of costs. 2 The survival rate can be clearly calculated. 3 convenient to measure feed and meat ratio. 4 is conducive to measuring the proportion of male and female pigs. 5 is conducive to the recording of blood and genetic factors of piglets. The quality of nursery and pig keeping and management not only affects the health status of the entire commercial pig, but also directly affects the economic interests of the farmer and is the first step in the success of breeding. Therefore, every step should be improved in the breeding process. Piglet survival rate, increase end-of-life weight.
