Problems solved by technology

The antibiotic drugs added in the feed will lead to the production of drug-resistant strains, making pigs have strong drug resistance, which will bring great technical difficulties to the disease prevention and treatment of pigs; at the same time, problems such as drug residues will also seriously affect people. good health
In addition, a large amount of copper, iron, zinc and other metal trace element feed additives and inorganic phosphorus are used in the feed, and the digestion and absorption efficiency of the animal body is not high, and some undigested and absorbed trace elements and inorganic phosphorus are excreted through the excretory system, which will also cause Environmental pollution such as soil compaction

Embodiment 1

[0021] A total of 360 healthy growing pigs of the breed "Du Changda" with a body weight of 20±2kg were randomly divided into 6 treatment groups, each treatment group had 6 replicates, and each replicate had 10 pigs. Six different premix additives were added to the basic test diet (referring to the nutritional requirements of pigs in NRC (2012) in the United States). The basic diet was divided into two stages: body weight 20kg-80kg, 80kg-120kg. See Table 1, and see Table 2 for the composition of premix additives.

[0022] Wherein, the carrier in Table 2 is prepared by mixing soybean meal powder, corn cob powder and fine rice bran meal, and the specific preparation method is: mixing soybean meal powder, corn cob powder and fine rice bran meal in a mass ratio of 4:4:2 Afterwards, it is dried until the water content is less than 2%, and then crushed until the particle size is less than 0.4mm.

Embodiment 2

[0049] In this example, the ingredients of the feed premix additives used in the test basal ration are shown in Table 5.

[0050] In this example, the premix additive for fattening pigs is prepared by the following method:

[0051] (1) Weigh lysine hydrochloride, threonine, DL-methionine, tryptophan, choline chloride and vitamins by weight percentage, and mix them with 65% of the total weight of the carrier for 25 minutes to prepare masterbatch A;

[0052] (2) Take composite trace elements, betaine, glycine chelated magnesium, sodium selenite and yeast chromium by weight percentage, and mix with remaining carrier for 20min to prepare masterbatch B;

[0053] (3) Take masterbatch A and masterbatch B and mix together for 40 minutes to prepare the premix additive.

[0054] The prepared premix additive was added to the basal ration for a feeding test. The composition of the basal ration is shown in Table 4.

[0055] Treatment 1a was the control group, and the remaining groups wer...

Embodiment 3

[0062] In this example, the feed premix additive components of the basal ration used in the test are shown in Table 7.

[0063] In this example, the premix additive for fattening pigs is prepared by the following method:

[0064] (1) Weigh lysine hydrochloride, threonine, DL-methionine, tryptophan, choline chloride and vitamins by weight percentage, and mix them with 65% of the total weight of the carrier for 30 minutes to prepare masterbatch A;

[0065] (2) Take composite trace elements, betaine, glycine chelated magnesium, sodium selenite and yeast chromium by weight percentage, and mix with the remaining carrier for 15 minutes to prepare masterbatch B;

[0066] (3) Take masterbatch A and masterbatch B and mix together for 35 minutes to prepare the premix additive.

[0067] The prepared premix additive was added to the basal ration for a feeding test. The composition of the basal ration is shown in Table 6.

[0068] Treatment 1b was the control group, and the remaining gro...

Abstract

The invention relates to a premix additive for fattening pigs. The premix additive comprises the following components by weight percent: 6% to 8% of lysine hydrochloride, 3% to 6% of threonine, 0.6% to 2% of DL-methionine, 0.2% to 0.7 of tryptophan, 1.5% to 1.8% of choline chloride, 1% to 1.5% of compound trace elements, 0.6% to 0.8% of vitamin, 0.4% to 0.8% of glycine betaine, 0.2% to 0.7% of magnesium glycinate, 0.2% to 0.4% of sodium selenite, 0.1% to 0.3% of chromium yeast and 79% to 83.1% of carrier. Compared with the prior art, the premix additive provided by the invention has the advantages that the feed quality is improved, the immunity of each pig body is enhanced and the digestive absorption of each pig body is promoted; after the glycine betaine, the magnesium glycinate, the sodium selenite and the chromium yeast are mixed with common raw materials such as corn, bean pulp and bran, the anti-stress ability of each pig body is enhanced, and thus the deposition rate of protein in pork is perfected so as to improve the pork quality; and in addition, the premix additive is sufficient in raw material source, low in cost and good in effect.

Description

technical field [0001] The invention relates to a feed additive, in particular to a premix additive for fattening pigs. Background technique [0002] At present, with the continuous development of scientific breeding technology, people have put forward higher requirements on how to improve the survival rate of livestock, reduce the occurrence of diseases, accelerate their growth rate and improve the quality of meat. As an indispensable part of the livestock breeding industry, feed is playing an increasingly significant role. In order to prevent diseases, promote rapid growth of livestock and poultry and improve feed utilization, nutritional additives such as vitamins, trace elements, and amino acids are usually added to full-price compound feed, as well as non-nutritive additives such as antibiotics, antifungal agents, and flavoring agents. . The antibiotic drugs added in the feed will lead to the production of drug-resistant strains, making pigs have strong drug resistanc...
