Definitions

  • the embodiments of the invention relate to the field of pig feed technology, and in particular to a pig feed for improving the content of unsaturated fatty acids in pork fat.
  • Unsaturated fatty acids have great effects on the physiological functions of the human body, such as: 1. Maintaining the relative fluidity of the cell membrane to ensure the normal physiological function of the cells; 2. Esterifying cholesterol and lowering blood cholesterol and triglycerides; Synthesize human prostaglandins and prostaglandin prosthetic substances; 4. Reduce blood viscosity, improve blood microcirculation; 5. Improve brain cell activity, enhance memory and thinking ability.
  • the -3 series of unsaturated fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) have a greater effect. DHA has been a major focus of child nutrition since the 1990s. Prof.
  • DHA is one of the important components of human brain development and growth.
  • EPA helps reduce cholesterol and triglyceride levels and promotes the metabolism of saturated fatty acids in the body. Thereby reducing blood viscosity, improving blood circulation, improving tissue oxygen supply and eliminating fatigue, preventing deposition of fat in the blood vessel wall, preventing the formation and development of atherosclerosis, preventing cardiovascular diseases such as cerebral thrombosis, cerebral hemorrhage and hypertension.
  • pork can be eaten and the body can take in the ingredients contained in pork.
  • DHA docosahexaenoic acid
  • EPA eicosapentaenoic acid
  • the invention provides a pig feed for improving the content of unsaturated fatty acids in pork fat, the microalgae containing eicosapentaenoic acid is added to the pig feed, and the weight content of eicosapentaenoic acid is zero thousandths Point five to one thousandth of a second.
  • the weight content of eicosapentaenoic acid in pig feed is from 10,000 to 10,000.
  • the weight content of eicosapentaenoic acid in pig feed is from four ten thousandths to six ten thousandths.
  • DHA docosahexaenoic acid
  • EPA eicosapentaenoic acid
  • the experiment used 120 ternary cross-breeding pigs of similar and healthy "Du Changda", half male and female, with an average body weight of 12.60 ⁇ 2.67kg. They were randomly divided into 12 groups according to the principle that the body weight is similar to that of the male and female. Group of 10 pigs.
  • the material to be pulverized is pulverized using a 2.5 mm sieve aperture, and then the ingredients are mixed.

Abstract

L'invention concerne une alimentation pour porcs permettant d'accroître la teneur en acide gras insaturé de la graisse de porc. L'aliment pour porcs contient des microalgues comportant de l'acide eicosapentaénoïque, la teneur en poids de l'acide eicosapentaénoïque étant de 0,005 % à 0,12 %. Cet aliment pour porcs permet d'accroître efficacement la teneur en acide gras insaturé de la graisse de porcs nourris à l'aide de cet aliment, en particulier, la teneur en acide eicosapentaénoïque et en acide docosahexaénoïque de l'acide gras insaturé oméga-3.
