Embodiment 1

[0039] Embodiment 1, the feeding effect of the additive containing uridine composition

[0040] Prepare a premix additive with disodium uridylate and uridine as raw materials, wherein the weight ratio of each raw material is: disodium uridylate: uridine: maltodextrin=100:90:800.

[0041] The ration of the control group was the basal ration, and the special feed for sows was prepared according to the following steps: the feed raw materials were referred to as follows by weight percentage: corn 65.0%; soybean meal 17.0%; wheat bran 8.0%; salt 1.0%; vegetable oil 2.0% ; Stone powder 2%; Calcium hydrogen phosphate 1%; After mixing evenly, the basic diet was obtained.

[0042] In the test group, 800 g / t of the premix additive of the present invention was added to the basal ration (that is, the weight ratio of uridine acid and uridine after mixing was about 0.015-0.016%).

[0043] Since the ingredients of the two basal diets were the same, the energy levels of the control group and...

Embodiment 2

[0048] Embodiment 2, the feeding effect of the additive containing uridine composition

[0049] According to the method of embodiment 1, prepare the feed of test group and control group, wherein test group 2 is to add 600g / t (that is, the weight ratio of uridine acid and uridine after mixing is about 0.012%) in the basal diet. Mixing additives.

[0050] Select 56 sows with the same weight and parity at about 65 days of pregnancy, and divide them into 2 groups at random, marked as control group 2 and test group 2, with 23 replicates in each group, and 1 sow for each replicate. The experimental group 2 was fed with the ration of the experimental group, and the control group 2 was fed with the ration of the control group. They were fed at 7:00 and 14:00 every day, and they had free access to food and water. The amount of feed should be a small amount. Record the amount of feeding in each column every day in detail, and collect and weigh the remaining materials the next day. The...

Embodiment 3

[0054] Embodiment 3, optimization of the content ratio of disodium uridine and uridine

[0055] According to the step of embodiment 1, prepare a plurality of test groups of feed additive, specifically as follows:

Record the amount of feeding in each column every day in detail, and collect and weigh the remaining materials the next day. The pre-feeding period was 5 days, and the test period was 80 days. Carry out following reproduction p...

Abstract

The invention discloses a compound fodder premixed additive for the gestation period of sows. The compound fodder premixed additive comprises, by weight, 40-150 parts of uridylic acid disodium, 40-150parts of uridine, 200-920 parts of carrier, 180-300 parts of NCG and 100-200 parts of chelate iron glycine, wherein the carrier is one of or the mixture of maltodextrin, starch, sepiolite and the like. The invention also discloses a preparation method of the compound fodder additive and fodder prepared from the additive for the gestation period of sows. The premixed additive only needs to be slightly added into the fodder, then the reproductive performance can be improved, the stillbirth rate is reduced, the diarrhea rate of piglets is decreased, and the compound fodder additive has a broad application prospect.

Description

technical field [0001] The invention relates to the field of animal feed industry, in particular to a compound feed premix additive for sows during pregnancy, in particular to a premix of uridine acid, uridine, NCG and glycine chelated iron for reducing stillbirth in sows Additives and their preparation and application. Background technique [0002] my country is the world's largest pig-raising and pork-consuming country. Pig production plays a very important role and status in my country's national economy, social stability and new rural construction. Sows are the source of pig production, and the breeding level of breeding sows as a supplier of commercial piglets directly restricts the benefits of pig farming. In recent years, the production level of sows in my country has been greatly improved, but compared with the pig-raising developed countries in the world, its production efficiency is at least 30% lower, and the number of sows required to produce the same number of ...
