Embodiment 1

[0015] A pig feed that improves estrus and lactation of sows, according to the weight ratio of lipoic acid to pig feed is 1:10 5 Lipoic acid is added to the pig feed, and the pig feed includes the following raw materials in parts by weight: corn 37.5, wheat bran 20.0, bean cake 9.0, bone meal 1.0, salt 0.4, and methionine:multidimensional weight ratio of 6:4 compound additive 0.5. The lipoic acid according to the above weight is stirred evenly with the raw materials of pig feed, mixed completely, and used for feeding sows to be delivered.

[0016] feeding experiment

[0017] A total of 18 sows of the same breed were selected, with basically the same parity, little difference in body weight, and healthy body condition. They were randomly divided into 2 groups with 9 pigs in each group. One group was the experimental group and the other was the reference group. The piggery was disinfected before the test, and the sows were fed to the two groups according to Table 1 below 10 day...

Embodiment 2

[0030] A pig feed for improving sow estrus and lactation, according to the weight ratio of lipoic acid and pig feed is 1:5×10 4 Lipoic acid is added to the pig feed, and the pig feed includes the following raw materials in parts by weight: corn 47.5, wheat bran 30.0, bean cake 19.0, bone meal 2.0, salt 0.5, and methionine:multidimensional weight ratio of 6:4 compound additive 1.0. The lipoic acid according to the above weight is stirred evenly with the raw materials of pig feed, mixed completely, and used for feeding sows to be delivered.

Embodiment 3

[0045] A pig feed that improves estrus and lactation of sows, according to the weight ratio of lipoic acid to pig feed is 1:10 4 Add lipoic acid to the pig feed, and the pig feed includes the following raw materials in parts by weight: corn 57.5, wheat bran 40.0, bean cake 29.0, bone meal 3.0, salt 0.6, and methionine:multidimensional weight ratio of 6:4 compound additive 1.5. The lipoic acid according to the above weight is stirred evenly with the raw materials of pig feed, mixed completely, and used for feeding sows to be delivered.

Abstract

The invention provides a feed additive capable of improving oestrus and lactescence of sows and the eggshell quality. The feed additive is obtained by adding lipoic acid into sow feed or chicken feed, and the lipoic acid serving as the feed additive is added into daily basic feed of the sows and chickens, so that the available nutritional level of the feed is improved, in-vivo hormone secretion of the livestock and poultry is regulated, the lactescence of the sows is improved, the survival rate of piglets is increased by means of prolongation of the lactation period, the eggshell quality can be enhanced to enhance resistance of eggs to bacteria, the shelf lives of the eggs are prolonged, and economic benefits are increased.

Description

technical field [0001] The invention relates to the field of animal feed production, in particular to a feed additive for improving sow estrus, lactation ability and eggshell quality. Background technique [0002] During the estrus and mating process of sows, the nutritional level of sows is extremely important. If the sows’ intake of feed nutrition cannot meet their needs, it will cause the sows’ metabolism to lose coordination, resulting in no estrus or delay in estrus. The reproductive efficiency of sows and the survival rate of newborn piglets determine the economic efficiency of a pig farm. Unbalanced nutrition and poor feeding management will lead to non-estrus or delayed estrus in multiparous sows, low pregnancy rate and low litter size, etc. Piglets mainly rely on breast milk to live after birth. The level of milk production of sows directly affects the survival rate, weaning weight and disease resistance of piglets. [0003] Similarly, with the improvement of peop...
