Current status of pig production:
1．Pig stocks drop dramatically due to ASFv --> Strong needs of high production sows
2．DLY sows are reserved for breeding purpose --> poor reproductive performance and short service life --> Strong needs of healthy sows
Common problems of lactating sows in actual production:
Insufficient milk secretion
Long farrowing time
Low proportion of wean-to-estrus within 7 days
This is more prominent on DLY sow, which seriously affect the production performance and profit.
Insufficient milk secretion
Long farrowing time
Litter weight at 25d-weaning is not up to standard
What we should do to improve reproductive performance of sows from nutrition perspective when breeds, environment and management are the same and in good condition?
1. Improving milk quality of sows
Providing sufficient raw materials for milk synthesis, promoting the full development of mammary glands, and sufficient suckling of the nipple can improve the milk quality of sows to provide higher litter weight at weaning.
2. Improve the health foundation of sows
During the post-gestation and lactation, the metabolism of sows accelerates, which produces a large amount of free radicals, resulting in a state of progressive oxidative stress of sows. Further causes the long farrowing duration, slow postpartum recovery, excessive weight loss during lactation, and abnormal estrus after weaning. Improvement of antioxidant capacity and reduction of oxidative stress will improve the health condition and reproductive performance of sows.
The Enzymatic Hydrolysate of Plant Protein (EHPP) of Mytech is rich in biologically active peptides (molecular weight <1000 Da), which can improve the lactation performance of sows and strengthen the health foundation of sows. Mytech and Sichuan Agricultural University conducted a research project together to make a deep study from performance of production effects to the mode of action, fully confirmed the function of EHPP on lactation sows.
Soybean bioactive peptides supplementation during late gestation and lactation affect the reproductive performance, free amino acid composition in plasma and milk of sows, Livestock Science 237 (2020)
Improve sow production performance: increase litter weight at weaning by 4kg, shorten the farrowing duration by 39min, and shorten the wean-to-estrus interval by 1.1d.
Mode of action 1. EHPP provides sufficient raw materials for milk synthesis
Improve the overall feed utilization efficiency and increase the content of total protein and total amino acids in serum
Mode of action 2. EHPP promotes development of mammary gland through increasing the concentration of functional amino acids in serum.
Significantly increase the level of functional amino acids in the blood of sows. Among them, valine provides energy for the growth of mammary gland cells and promotes more sufficient development of mammary glands (Trottier, 1994); histidine stimulates mammary gland cell proliferation and differentiation, stimulates angiogenesis and increases blood flow through the mammary gland (Wanger, 2003); Arginine increases blood flow to the mammary gland and promotes the growth and development of breast cells (kim, 2010).
Mode of action 3. EHPP improves milk quality
Improve the levels of IgG in colostrum, IgM and taurine in normal milk.
IgG in colostrum and IgM in normal milk are the main active ingredients for suckling pigs to obtain passive immunity, which can effectively enhance the resistance of suckling pigs to diseases, reduce the number of mortality, and increase the weaned size.
Significantly increase the level of functional amino acids in milk. Lysine is the first indispensable amino acids for the growth of suckling piglets; arginine is used as a semi-indispensable amino acid; glutamic acid and glutamine provide energy for the growth of intestinal epithelial cells, which can effectively protect the intestinal development of suckling piglets and accelerate the growth rate, and increase weaning weight.
Mode of action 4. EHPP reduces oxidative stress of sows
Significantly reduce the sow oxidative damage product MDA in serum, increase somatic total antioxidant capacity, and improve the health foundation of sows.
Enzymatic hydrolysate of plant protein (EHPP) is rich in biologically active peptides (molecular weight <1000Da: anti-oxidant peptides, anti-inflammatory peptides, etc). Authoritative research results have confirmed that EHPP can improve the lactation performance, reproductive performance of sows. It is an effective choice to improve sow production performance and farming efficiency.
