Basic knowledge of pig breeding, three basic growth stages need to be scientifically fed

The feeding process of pigs is mainly divided into three stages: the lactation stage: piglets should eat good colostrum and keep warm after birth, and diseases of red, yellow and white dysentery should be prevented. Conservation stage: the weaned piglets were reasonably managed in groups, and the diet was changed from liquid breast milk to feed. Growth and fattening stage: at this stage, a single feed will cause malnutrition and affect the growth rate of piglets, so it is necessary to feed scientifically, deworming and vaccination on time.

1. Living environment

Pigs should live in a dry, ventilated and transparent place, which can provide a clean and tidy environment for pigs to grow better, reduce the infection of harmful bacteria and reduce the prevalence of pigs.

2. Lactation stage

Temperature: piglets should eat colostrum well after birth, because newborn piglets are afraid of cold. The temperature should be kept at about 30 ℃-32 ℃ in 1-3 days, 28 ℃-30 ℃ in 4-7 days, and 22 ℃-25 ℃ in 8-30 days. As the date of birth increases, the temperature will get lower and lower until the room temperature.

Disease prevention: to prevent red, yellow and white dysentery of piglets, the most important thing is to give piglets a clean living environment, followed by drug prevention.

The piglets can be given oral 2ml-3ml with 0.1% potassium permanganate aqueous solution, and then the rest can be put into drinking water for piglets to drink.

Or soak one jin of garlic and six taels of licorice with one jin of liquor for 5-7 days, take 1 ml of raw juice and 4 ml of water, twice a day.

You can also add tumeisu in supplementary feeding for prevention, or take dysentery 0.4 g-0.5 g per head daily for two times or sulfamide 1 g-2 g twice a day for 3 days.

Diet: piglets should be weaned in 30-40 days, and feed should be replenished in 7-10 days. Don't forget to keep the place where piglets eat feed clean and tidy, and put on fresh drinking water every day. In this way, the piglets can bring better economic benefits.

3. Conservation stage

After weaning, piglets should start to change from the main nutrition, from warm liquid breast milk to solid raw and dry feed, from relying on sows to living completely independently, and from the delivery room to the nursery. It is also easy to be infected with bacteria and lead to illness, so it is necessary to strictly ensure the living environment of piglets and the defense against viruses, and to manage the weaned piglets into groups reasonably. At this stage, piglets lose weight, become weaker, and the probability of disease increases. If raised improperly, it is easy to form stiff pigs, which eventually leads to piglet death.

4. Growth and fattening stage

To choose lean pigs as a foothold for the development of pigs, you can not always feed piglets with a single feed, which will cause malnutrition, waste feed, slow down the growth of piglets, and deworming piglets for 1-2 times. body surface deworming can be used with 0.5% color trichlorfon solution spray to kill body surface lice, mites and other insects. Oral deworming allows pigs to take albendazole 5ml-40 ml per kilogram of body weight and levamisole hydrochloride 8 ml per kilogram of body weight. It is best to be accompanied by a veterinarian to avoid poisoning, and pigs should be vaccinated against classical swine fever.

5. out of the column at the right time.

The fattening pig had better grow to 90kg-120kg and is most suitable for slaughtering. if it is less than 90kg, the probability of producing meat is very low and the economic benefit is low. if it is higher than 90kg, the pig is mainly fat deposition, for example, the weight of binary pig reaches 70kg, the weight of inner three pig reaches 80kg-85kg, the weight of outer ternary pig reaches 95kg, and the weight of British PIC pig reaches 105kg. At this time, the pig will be out of the pen, if the market price is high, the pig's weight is as heavy as possible, on the contrary, when the market price is low, the pig's weight is light, which can reduce the cost and feed consumption.
