Feed additive with capacity of increasing egg yield of Ruddy Shelducks and preparation method of feed additive

Abstract

The invention discloses a feed additive with capacity of increasing egg yield of Ruddy Shelducks and a preparation method of the feed additive. The feed additive is prepared from raw materials in parts by weight as follows: 20-30 parts of oat bran, 8-14 parts of glutinous corn meal, 5-10 parts of brown rice flour, 12-16 parts of soybean meal, 6-12 parts of swine blood meal, 18-24 parts of locust powder, 10-16 parts of housefly maggot meal, 15-20 parts of Margarya melanioides meal, 7-13 parts of loach meal, 15-20 parts of silver carp powder, 20-26 parts of Eleocharis acicularis, 12-16 parts of duckweed, 18-24 parts of Crinum calamistratum, 10-14 parts of cassia twigs, 5-10 parts of perilla leaves, 8-12 parts of fruits of negundo, 30-40 parts of an appetizer and an appropriate amount of water. According to the feed additive with the capacity of increasing the egg yield of the Ruddy Shelducks, the components are effectively mixed, a formula is scientific and reasonable, the utilization rate of feed is high, rapid growth of the Ruddy Shelducks can be promoted, so that the egg yield of the Ruddy Shelducks is increased, illness rate of the Ruddy Shelducks can be reduced, and survival rate of the Ruddy Shelducks can be increased.

Description

technical field [0001] The invention relates to a feed additive, more precisely, a feed additive capable of increasing the egg production of ruddy shelducks and a preparation method thereof. Background technique [0002] The red shelduck is larger in size, with a body length of 51-68 cm and a weight of about 1.5 kg, which is slightly larger than the domestic duck. The whole body is reddish brown, with obvious white wing spots and copper green wing mirrors on the wings; the beak, feet and tail are black; the male bird has a black neck ring. In flight, black flight feathers, tail, beak and feet, tawny body feathers and white wing coverts and underwing coverts form a sharp contrast. Inhabit open grasslands, lakes, farmland and other environments, and feed on various grains, insects, crustaceans, frogs, shrimps, and aquatic plants. [0003] In recent years, more and more intensive and large-scale breeding of shelducks have been carried out with compound feed in my country. Ho...

Problems solved by technology

However, the existing feed nutrients are not very reasonable, and the single composition cannot provide all the nutrients needed for the growth of the shelduck, which affects its growth rate and leads to low egg production; moreover, the existing feed also contains various hormones, which affect The eating taste of the red shelduck eggs has also pushed up the prevalence of red shelducks
