Problems solved by technology

If purchased too late, the sows are too heavy, and they have probably been raised as fattening pigs, which is not good for reproduction
On the other hand, the purchased gilts are too late, and there is not enough time to adapt to the own farm, which may cause reproductive failure

Embodiment 1

[0025] A feeding method for gilts, according to the following steps:

[0026] 1) Lactation and weaning period: a total of 28 days, feeding lactation feed, add 2.5% backup feed additive by weight to the lactation feed, feeding amount 2.0-2.2kg per head per day, feeding twice a day, 9:00- 10:00 feeding 2 / 3 of the total daily feed volume, 16:00-17:00 feeding 1 / 3 of the total daily feed volume;

[0027] 2) Weaning and mating period: a total of 7 days, feeding pregnancy feed, adding 2.0% backup feed additive by weight to the pregnancy feed, feeding 1.5-2.0kg per head per day, feeding 3 times a day, 10:00- 1 / 2 of the total daily feed at 11:00, 1 / 3 of the total daily feed at 17:00-18:00, and 1 / 6 of the total daily feed at 21:00-22:00;

[0028] The feed additive for gilts is obtained by the following preparation method:

[0029] 1) Raw material processing: grinding fresh immature mangosteen and fallen mangosteen to remove the fluff on the surface of the mangosteen;

[0030] 2) Subcritical wat...

experiment example

[0045] The feed additive of the present invention was tested separately in the pig farm of our company.

[0046] Example 1 group: using the method of Example 1;

[0047] Comparative example 1 group: adopt the method of comparative example 1;

[0048] Comparative example 2 group: adopt the method of comparative example 2;

[0049] Control group: no special feed additives for gilts were used, and the others were the same as in Example 1.

[0050]

[0051]

[0052] Conclusion: The use of the feed additive of the present invention can effectively increase the estrus rate of gilts, and at the same time, can effectively prevent pigs from having gastrointestinal problems.

Abstract

The invention discloses a feeding method for replacement gilts. The feeding method for replacement gilts comprises the following steps: (1) lactation and weaning period: lasting the lactation and weaning period for 28 days, feeding a lactation material, and adding 2.5% of a replacement feed additive in the lactation material according to the weight, wherein the feeding amount of every gilt is 2.0-2.2 kg every day, every gilt is fed twice every day, every gilt is fed with the feed which accounts for 2 / 3 of the daily total feeding amount in a time interval of 9: 00-10: 00, and every gilt is fedwith the feed which accounts for 1 / 3 of the daily total feeding amount in a time interval of 16: 00-17: 00; and (2) weaning and hybridization period: lasting the weaning and hybridization period for 7days totally, feeding a pregnancy material, and adding 2.0% of replacement feed additive in the pregnancy material according to the weight, wherein the feeding amount of every gilt is 1.5-2.0 kg every day, every gilt is fed three times every day, every gilt is fed with the feed which accounts for 1 / 2 of the daily total feeding amount in a time interval of 10: 00-11: 00, and every gilt is fed withthe feed which accounts for 1 / 6 of the daily total feeding amount in a time interval of 21: 00-22: 00.

Description

Technical field [0001] The invention belongs to the technical field of pig breeding, and particularly relates to a feeding method for gilts. Background technique [0002] The gilt is a term used in pig production and generally refers to the sow that has not been selected for breeding. In most breeding farms and in some cases, it also refers to pigs that are young sows and female pigs that are selected for use until the first farrowing. [0003] Generally, gilts are used to supplement sows that are eliminated due to older age, poor reproductive performance or disease, so that the production sows maintain a composition structure of young and mature age. In pig production, it is necessary to constantly update sows, that is, while weed out sows that are slow in heat, weak in old age, poor lactation ability, and reproductive disorders, timely selection of high-quality and improved gilts for supplementary production. The so-called gilt refers to the sow that is kept for breeding before...
