Problems solved by technology

This patent is mainly aimed at improving the physiological and nutritional needs of sows in the empty pregnancy stage, which is conducive to maintaining the reproductive health of sows, and has a certain effect on solving the problem of sows not in estrus in the empty pregnancy stage. Although the raw material formula of the concentrated feed of this patent uses puffed soybean meal, However, the content of oil in puffed soybean meal is relatively low, and the energy level is relatively low, which is not conducive to promoting the estrus and mating of sows, and the formula of the concentrated feed of the above patent is relatively complicated. Additives such as phytase will increase the production cost of concentrate products accordingly, and it is difficult to mix the above raw materials evenly, and the preparation process of the entire concentrate is relatively complicated

Embodiment 1～5

[0034] 120 healthy gilts with a body weight of 120±2kg were randomly divided into two treatment groups. The control group feeds conventional rations for gilts (with reference to U.S. NRC (2012) pig nutrition needs to prepare rations), and the embodiment group adds the concentrated feed of the present invention. In each embodiment group, the composition of the concentrated feed is shown in table 3.

[0035] Wherein, the preparation method of concentrated feed comprises the following steps:

[0036] (1) Glutinous rice is added in the hammer mill, fully pulverized, until the particle fineness of pulverization is 20 orders, promptly makes glutinous rice flour;

[0037] (2) prepare materials by weight percentage of corresponding composition;

[0038](3) Add soybean isoflavones and fish meal into the blender according to the weight percentage in step (2), adjust the rotating speed of the blender to be 30 rpm, and the mixing time is 200 seconds. After mixing evenly, the mixture is ...

Embodiment 6

[0059] In this embodiment, the concentrated feed includes the following ingredients in weight percentage: 30% fish meal, 2% corn oil, 30% glutinous rice flour, 37.5% brown sugar and 0.5% soybean isoflavones; the concentrated feed is added to the conventional feed for breeding and breeding The gilts of the first 15 days, wherein the concentrated feed accounted for 18% by weight of the conventional feed.

[0060] Among them, the fish meal is a fish meal made by mixing herring meal, Manhattan fish meal and sardine meal at a mass ratio of 1:1:1. The main components and weight percentages of the sardine meal are: more than 68% of crude protein, 5.5-5.9% of crude fat, Calcium 3.5%, phosphorus 2.9-3.1%, volatile base nitrogen 60% or less; glutinous rice flour has a particle size of 20 meshes, which is prepared by grinding glutinous rice after shelling, crude protein, crude fat, The weight percentages of crude fiber, ash, calcium and phosphorus are 11.2%, 2.1%, 1.5%, 1.8%, 0.05% and 0...

Embodiment 7

[0069] In the present embodiment, the concentrated feed includes the following ingredients in percentage by weight: 12% fish meal, 5% corn oil, 50% glutinous rice flour, 32.7% brown sugar and 0.3% soybean isoflavones; the concentrated feed is added to the conventional feed for breeding and breeding The gilts of the first 15 days, wherein the concentrated feed accounted for 20% by weight of the conventional feed.

[0070] Among them, the fish meal is fish meal made by mixing anchovy meal and sardine meal at a mass ratio of 1:3. The main components and weight percentages of sardine meal are: more than 68% crude protein, 5.5-5.9% crude fat, 3.5% calcium, phosphorus 2.9-3.1%, volatile basic nitrogen 60% or less; the particle size of glutinous rice flour is 20 meshes, which is prepared by crushing glutinous rice after shelling, crude protein, crude fat, crude fiber, ash, The weight percentages of calcium and phosphorus are 11.2%, 2.1%, 1.5%, 1.8%, 0.05% and 0.35%; in soybean isofla...

Abstract

The invention relates to a concentrated feed applied to sows before mating. The concentrated feed comprises the following components in percentage by weight: 10-30% of fish meal, 2-10% of corn oil, 29-50% of glutinous rice flour, 30-38% of brown sugar and 0.1-0.5% of soy isoflavone. The concentrated feed is added into the normal feed and is used for feeding remount sows 15 days before mating, wherein the concentrated feed is 15-20% of the conventional feed; a preparation method of the concentrated feed comprises the following steps: uniformly mixing the soy isoflavone with the fish meal according to the percentage by weight to prepare a mixture A during preparing, uniformly mixing the corn oil, the brown sugar and the glutinous rice flour to prepare a mixture B, finally, fully mixing the mixture A with the mixture B to prepare the concentrated feed. Compared with the prior art, the preparation method of the concentrated feed is simple in process; the method is characterized by mixing step by step; all the raw materials can be uniformly mixed; the concentrated feed prepared by the method can be used for effectively increasing the estrogen level in the sow bodies; the gilts during oestrous is accelerated; the number and the quality of ova are improved; the sow reproduction is improved.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and relates to a concentrated feed, in particular to a concentrated feed used before mating of sows. Background technique [0002] Nowadays, with the continuous improvement of pig breeding technology, the pig breeding structure is rapidly developing towards a large-scale, intensive and professional farming model. Among them, litter size is an important indicator to measure the reproductive performance of sows, and increasing the litter size of the first litter of sows will help improve the lifelong reproductive performance of sows. However, energy levels and sources in diets used for gilt rearing can significantly affect puberty onset, oestrus rate, and oocyte quality in sows. Studies have found that high energy levels significantly promote the secretion of Insulin, IGF-1 and Leptin in the blood, increase the secretion frequency of LH, thereby increasing the estrus rate and ovulation rate o...
