Embodiment 1

[0013] 1. Test diet

[0014] The experimental basal diet was formulated with reference to the nutritional requirements of pregnant sows in the US NRC (1998), the pig breeding standards promulgated by the Ministry of Agriculture of China in 2004, and the "Chinese Feed Composition and Nutritional Value Table (20th Edition, 2009)". The composition and main nutrient levels are shown in Table 1. In the experimental group, 80 mg / kg lycopene was added instead of corn on the basis of the basal diet.

Abstract

The invention provides a gestation period feed additive for improving reproductive performance of sows and a feed thereof. The feed additive is characterized in that every kilogram of feed for the sows in the gestation period contains 80mg of lycopene. The gestation period feed for improving the reproductive performance of the sows comprises the following components in percentage by weight: 67.492percent of corn, 13.500 percent of wheat bran, 16.000 percent of bean pulp, 1.100 percent of mountain flour, 1.000 percent of calcium hydrophosphate, 0.400 percent of salt, 0.350 percent of trace element premix, 0.150 percent of vitamin premix and 0.008 percent of lycopene. The problems of small litter size of the sows, more dead fetuses, intrauterine growth retardation of fetuses and the like are solved, and the total litter size, live litter weight and placenta weight of the sows are obviously improved.

Description

technical field [0001] The invention specifically relates to a pregnancy feed additive and feed for improving the reproductive performance of sows. Background technique [0002] Lycopene, a carotenoid found in plant foods, is also a red pigment. Deep red needle crystal, soluble in chloroform, benzene and oil, insoluble in water. It is unstable to light and oxygen, and turns brown when it encounters iron. Molecular formula C40H56, relative molecular mass 536.85. There are 11 conjugated double bonds and 2 non-conjugated double bonds in the molecular structure, forming a straight-chain hydrocarbon. It does not have the physiological activity of vitamin A, but has a strong antioxidant function. The content is higher in ripe red plant fruits, especially in tomato, carrot, watermelon, papaya and guava. It can be used as a pigment in food processing, and is also often used as a raw material for antioxidant health food. Lycopene has been proven to enhance the body's oxidative ...
