Embodiment 1

[0055] The feeding method of pregnant and lactating sows comprises the following steps:

[0056] (1) Feeding during pregnancy

[0057] A. After the sows are mated, prepare gestational feed to feed the sows. The feeding amount is as follows: the daily feeding amount in the early pregnancy is 2kg / head, the daily feeding amount in the middle pregnancy is 2.5kg / head, and the daily feeding amount in the late pregnancy is 3kg / head.

[0058] The feed during pregnancy is made by mixing the following raw materials in parts by weight: 50 parts of corn, 30 parts of wheat bran, 25 parts of rice flour, 20 parts of soybean meal, 3 parts of alfalfa meal, 3 parts of fish meal, 3 parts of bone meal, and 2 parts of shell meal. 0.5 part of salt, 0.4 part of mineral element additive, 00.05 part of vitamin additive, and 0.6 part of vegetable oil.

Abstract

The invention discloses a raising method of sows at a gestation period and a lactation period, and belongs to the technical field of pig breeding. The raising method comprises the following steps of raising the sows at the gestation period and raising the sows at the lactation period, wherein the sows at various periods are raised through a specially-prepared gestation period feed and a specially-prepared lactation period feed in a quantified manner, nutrients required for the sows at the various periods are balanced, and the number born of the sows and the birth quality of the sows can be effectively increased. A miscarriage preventing agent is used in three periods when embryo death is easy to cause in the gestation period to prevent miscarriage, so that the embryo mortality can be greatly reduced. A lactation promoting agent is added during the lactation period, sufficient nutrients for piglets can be guaranteed, normal development of the piglets can be realized, and the mortality rate of the piglets can be reduced.

Description

technical field [0001] The invention relates to the technical field of pig breeding, in particular to a feeding method for pregnant and lactating sows. Background technique [0002] In the breeding process of sows, since gestation and lactation are special periods in the process of raising sows, sows have special needs for nutrition in these two periods, and feed nutrition during pregnancy affects the number of piglets produced and the number of piglets First weight, the nutrition intake of lactating sows not only affects the postpartum physique of sows, but also affects the growth of piglets. Sows have less lactation and poor milk, which will lead to weak piglets, easy to get sick, and low weaning weight. [0003] After the sow is pregnant, there are three special periods that are likely to cause embryonic death, which are 9-13 days, 18-24 days, and 60-70 days. The first peak occurs on days 9-13. At this time, the fertilized egg begins to contact the uterine wall and is re...
