Problems solved by technology

[0006] In addition, phytic acid is commonly found in vegetable feed, especially in oilseed cakes. A large number of studies have confirmed that phytic acid in canola meal will reduce the digestibility and utilization of minerals, proteins, starches and lipids.

Embodiment 1

[0028] The feed for growing and finishing pigs without soybean meal includes the following components in parts by weight:

[0029] Corn 50-80 parts, rapeseed meal 15-35 parts, bran 0.5-10, rice bran 1-8, stone powder 0.6-2, calcium hydrogen phosphate 0.2-1.2, salt 0.1-0.8, lysine 0.1-1, methionine 0.01 -0.15, threonine 0.01-0.4, tryptophan 0.01-0.1, valine 0.01-0.15, choline chloride 0.01-0.1, rapeseed meal special compound enzyme 0.02-0.15, fattening pig compound premix 0.1-1 .

[0056] 1. Experimental Animals and Diets

[0057] In the experiment, 240 Xinmei three-element fattening pigs with body weight of (41.78±1.93) kg were randomly divided into 4 groups according to the principle of similar body weight, with 6 replicates in each group and 10 pigs in each replicate (column). The test period is 23 days. The diet composition and nutrient levels are shown in Table 4.

[0060] 2. Test method

[0061] The experiment adopted a 2×2 factorial design, and the main factors were dietary treatment and compound enzyme treatment. Dietary treatment: corn soybean meal-based diet or rapeseed meal-based diet. Compound enzyme treatment: general compound enzyme and special compound enzyme for rapeseed meal, see Table 5 for compound enzyme zymogram. During the test period, feed and water were provided ad libitum, and the feed intake an...

Abstract

The invention discloses a growing-finishing pig feed using rapeseed meal instead of soybean meal. The feed comprises the following components in parts by weight: 50 to 80 parts of corn, 15 to 35 parts of rapeseed meal, 0.5 to 10 parts of bran, 1 to 8 parts of rice bran, 0.6 to 2 parts of mountain flour, 0.2 to 1.2 parts of calcium hydrogen phosphate, 0.1 to 0.8 part of table salt, 0.1 to 1 part of lysine, 0.01 to 0.15 part of methionine, 0.01 to 0.4 part of threonine, 0.01 to 0.1 part of tryptophan, 0.01 to 0.15 part of valine, 0.01 to 0.1 part of choline chloride, 0.02 to 0.15 part of special compound enzyme for rapeseed meal and 0.1 to 1 part of fattening pig compound premix. According to the preparation method of the growing-finishing pig feed by replacing the soybean meal with the rapeseed meal, the utilization efficiency of the rapeseed meal can be greatly improved by screening and adding the special enzyme for the rapeseed meal with a proper proportion and a proper level, full replacement of the soybean meal in the feed is realized, moreover, the feed intake, daily gain and feed conversion ratio of the pigs are equal to those of pure corn-soybean meal type daily ration, and a series of problems that the feed product cost is increased, the profit margin of farmers is compressed and the like due to the fact that the price of the soybean meal is continuously increased are finally solved.

Description

technical field [0001] The invention belongs to the technical field of animal nutrition, and in particular relates to a feed for growing and finishing pigs in which rapeseed meal replaces soybean meal. Background technique [0002] Soybean meal is a by-product of soybean oil removal, with a crude protein content as high as 43% to 48%, high content of essential amino acids such as lysine and threonine, and has the characteristics of high digestion and absorption rate, good amino acid composition, and stable quality. It is a common and widely used plant protein raw material in feed. [0003] my country is the largest soybean consumer in the world, and more than 80% of soybean consumption depends on imports. However, in recent years, affected by factors such as fluctuations in foreign soybean production capacity, Sino-US trade frictions, and the new crown epidemic, the price of soybeans has continued to rise, and the price of soybean meal has also risen accordingly, and has re...
