Embodiment

[0023] 400 "Landrace" gilts weighing 20kg were randomly divided into 5 treatment groups, with 80 Landrace gilts in each treatment group. During the back-up breeding period, the basal diet (control group) was formulated according to the nutritional requirements of pigs in the US NRC (1998). At the beginning of the test, the additives of the present invention (4 combinations in different proportions) were added to the basal ration respectively, as a test group, and the best combination was screened.

[0024] After the backup period, all sows were fed with the same feed for pregnant sows (provided by Fujian Aonong Biotechnology Group Co., Ltd., compound feed for pregnant sows) or feed for lactating sows (provided by Fujian Aonong Biotechnology Group Co., Ltd. , compound feed for lactating sows), the test period was 2 years. During the experiment, the feeding management procedures and immunization procedures were carried out according to the conventional commercial pig feeding ma...

Abstract

The invention relates to a replacement-gilt feed additive and application thereof. The feed additive is prepared from components including, by weight, 0.3-0.5 part of 1, 25-dihydroxy cholecalciferol, 45-60 parts of calcium lactate, 2.5-5.0 parts of glycine manganese, 5.0-7.5 parts of glycine zinc, 1.0-3.0 parts of methionine copper, 20-25 parts of zeolite powder and 10-25 parts of corncobs. The application of the replacement-gilt feed additive includes adding the feed additive into basic ration during cultivation of replacement gilts, and feeding the replacement gilts with the feed additive and the basic ration, wherein the feed additive accounts for, by weight, 1% of the basic ration. Compared with the prior art, the feed additive has the advantage that various organic microelements and the 1, 25-dihydroxy cholecalciferol serve as main materials. When the feed additive is added into conventional feed, the replacement gilts can deposit more micro mineral elements, so that hoof growth is promoted, bone strength and density are enhanced and hoof cracking of the gilts is relieved.

Description

technical field [0001] The invention relates to a feed additive and its application, in particular to a gilt feed additive and its application. Background technique [0002] With the progress of pig genetics and breeding, the growth rate of pigs is getting faster and faster. Landrace sows have slender limbs and hooves, and the hooves are thin and tender. With the increase in weight, the pressure on the hooves is gradually increasing, which is prone to cracked hooves. Cleft hooves are more likely to develop after being stimulated by stress factors such as vaccinations, stocking density, sudden changes in temperature and humidity, and fright. [0003] The problem of limbs and hooves is an important reason why gilts cannot be kept. Gilts with cleft hooves and swollen joints may have problems in future use and are not suitable for continued breeding. [0004] Chinese patent CN 102308926 A discloses a feed additive that can effectively treat cleft hooves of boars, which is made...
