improve growth performance

①Yin XiaofengWaitIn the study of the effects of different copper sources on the growth and development of piglets and fecal copper content, it was found that compared with the control group, the weaned piglets with organic trace elements wereBoth feed intake and daily gain were increased.

Weaned piglets in which small peptides chelate trace elements are addedThe feed intake increased by 1.2 per cent, the daily gain increased by 4.44 per cent, and the feed-to-gain ratio decreased by 2.7 per cent..

②Li Shaohua et alUsing small peptide chelated copper and small peptide chelated zinc to replace copper sulfate and zinc sulfate in the basal diet of piglets (test group), the results showed that at the age of 36 to 90 days, compared with the control group (I. e. piglets with copper sulfate and zinc sulfate), the averageDaily gain increased by 8.8 per cent and material-to-weight ratio decreased by 8.6 per cent..

③Li Yao, etcPiglets were added inorganic trace elements (control group), small peptide chelated trace elements inorganic trace elements (test group I), total organic trace elements (test group II) to test piglets performance.

The results showed that compared with the control group, the average daily gain, average daily feed intake and feed-to-weight ratio of piglets in the experimental group I and the experimental group II were increased. especiallyIn group I, the average daily gain and average daily feed intake increased by 6.1 and 5.3, respectively, and the feed-to-weight ratio decreased by 0.5..

④ Wu Xin et al.Piglets were fed with small peptide chelated iron (dipeptide) and ferrous sulfate, respectively. The results showed that compared with the ferrous sulfate group, the daily gain of small peptide chelated iron group increased by 10.37, and the feed-to-weight ratio decreased by 5.59, which significantly promoted the growth performance of weaned piglets.

Conclusion

Through the above research shows that,Compared with inorganic trace elements, small peptide chelated trace elements have better effect in promoting piglet growth and improving feed remuneration.

improve digestion and absorption rate

Emission reduction and environmental protection

① Ding Ruizhi et alAmino acid trace element chelate (group A), small peptide trace element chelate (group B) and organic trace element (group C) were used to prepare low copper complex trace element additives to replace trace elements in the basal diet of piglets, respectively.

The results showed that from the first day of the experiment, the Cu content in the feces of piglets fed low copper level diets decreased significantly. On the 21st day of the experiment, piglets in each treatment groupThe fecal content decreased by 61.57, 83.1 and 49.82, respectively; on the 35th day of the experiment, the feces of piglets in each treatment group decreased by 66.44, 81.85 and 49.37, respectively..

The use of chelated copper in accordance with the trace element balance technology to prepare piglets low copper diet, can.Significantly reduced fecal Cu excretion in piglets50% to 80%, of whichThe role of small peptide sequestration of trace elements is the most significant.

② Li Ling et alThe study reported that replacing trace elements in the basal diet of piglets with small peptide trace element chelate (test group 2) can significantly reduce the content of copper, iron, manganese, zinc and selenium in piglet feces,The most significant of these was the manganese content, which was significantly reduced by 11.02 percent..

③ Yu Sihua, etc.There are also related studies, the results show that compared with inorganic trace elements,Low-dose small peptide chelated copper and small peptide chelated zinc instead of high-dose sulfate source copper and zinc can greatly reduce the emission of copper and zinc in feces.

Conclusion

The above results can be shownSmall peptide chelate trace element digestibility is better than inorganic trace elements, hasHigher biological potency.

And compared to inorganic trace elements, canReduce the amount of addition, increase utilization,Reduce the content of trace elements in fecesIt is of great significance to reduce the pollution caused by pig industry to the environment.
