Embodiment 1

[0026] The trial was conducted at Texas Greenleaf Hog Farm. 300 long-term binary hybrid sows raised in the pig farm were randomly divided into control group, test 1 group and test 2 group. The test period was 85 days, covering the entire first trimester. During the experiment, the control group was fed the control diet, and the experimental group was fed the experimental diet 1. Test 2 group was fed with test 2 diet. Each group was fed with 3.3kg per head per day, that is, each group was fed with 330kg per day. After the experiment, all three groups were fed with the same amount of dry powdered complete compound feed for sows. The dry powdered complete compound feed for sows is produced by Dezhou Chia Tai Company.

[0027] The diet of the control group: dry powdered complete compound feed for sows.

[0028] Trial 1 diet production and feeding: Harvest the whole plant green corn stalks from the middle stage of milk ripening to the early stage of wax ripening, first crush t...

Embodiment 2

[0032] The experiment was carried out on a pig farm in Jiyang County, Jinan City. 400 pregnant sows were raised on a pig farm in Jiyang County, and they were randomly divided into two groups. The control group was fed with dry powdered full-price feed for sows, and the experimental group was fed with fermented green straw feed and dry powdered feed for sows. Mixture (test diet). The 200 sows in the control group consumed 400 kg of dry powder feed per day in the early pregnancy and 800 kg in the late pregnancy. The experimental group was fed the same dose of the experimental diet. The test period is the whole gestational period (early pregnancy and late pregnancy), 114 days. Dry powdered complete feed for sows is produced by Shandong Bangji Company.

[0033] Production and feeding of the test diet: Harvest the green corn stalks of the whole plant, first use a hay cutter to shorten it to 2 cm, and then use a beater to beat it and pulverize it. The particle size after beating ...

Embodiment 3

[0036] The experiment was carried out on a pig farm in Pingyin County, Jinan City. 2,000 fattening pigs were raised on a pig farm in Pingyin County. According to the principle of equal body weight, they were randomly divided into two groups. Mixture of dry powdered complete feed for finishing pigs (test diet). The feed intake of 1000 fattening pigs in the control group was 3600 kg per day, and the test group was fed with the same dose of test diet. The test period is 35 days. Dry powder full-price compound feed for fattening pigs was produced by Shandong Huamu Tianyuan Company.

[0037] Preparation and feeding of experimental diets. Harvest the green wheat stalks of the whole plant, first shorten it to 2cm with a hay cutter, and then use a beater to beat it and pulverize it, and the particles after beating and pulverization are 0.3cm. The wheat straw granules and the bran added with exogenous bacteria were mixed at a weight ratio of 11:1 and quickly packed into plastic bag...

Abstract

The invention discloses a method for preparing pig feed by using green straw. In the present invention, the whole plant corn stalk or wheat straw is crushed to a particle size of 0.2-0.3 cm, and the crushed fine straw particles are mixed with bran or bran added with exogenous bacteria (a mixture of exogenous composite bacteria and microbial accelerators) , anaerobic fermentation in plastic bags for 7‑10 days, and then mixed with sows or growing and finishing pigs for feeding. The method reduces the particle size of the crushed straw, shortens the fermentation time with the assistance of exogenous bacteria and microbial accelerators, improves the fermentation effect, and promotes the feed utilization of corn straw and wheat straw. Because wheat and corn are planted alternately, and corn stalks and wheat stalks are fermented and fed successively, pigs can be fed throughout the year.

Description

technical field [0001] The invention relates to a method for preparing pig feed by using green stalks (corn stalks or wheat stalks), and belongs to the technical field of animal husbandry. Background technique [0002] There are several key restrictive factors in my country's intensive pig production, among which the price of feed raw materials has increased too fast, the price of corn and soybean meal has risen by more than 20%, and the rapidly rising feed cost has restricted the development of pig industry. At present, my country's feed rations generally refer to the NY / T65-2004 standard, which is formulated on the basis of corn-soybean meal rations. The rise in raw material prices leads to an increase in feed production costs, reduces the benefits of pig raising, and leads to long-term pig raising. In the stage of small profit or loss state. [0003] my country's main crops are corn and wheat. Green corn stalks and green wheat stalks are cheap and juicy. Using green stal...
