Problems solved by technology

In the prior art, although there have been reports on regulation and control through nutritional approaches, most of them are the impact of a single nutritional element on egg production performance, and the measurement of egg production performance indicators is not comprehensive at the same time, without considering the impact of multiple nutritional elements on egg production. Combined Effects on Egg Production Performance

specific Embodiment

[0013] The experiment was carried out on the layer farm of Kunshan Zhoujiu Ecological Farm Co., Ltd., 46-week-old Jingfen layer (produced by Beijing Yukou Poultry Company) 360 were randomly divided into 13 groups, each with 90 birds, the first 3 groups were respectively Feeding with 0.3%, 0.6% and 0.9% rosemary vanilla powder; V C , V E There are 3 levels for the addition of soybean oil and soybean oil, which are represented by 1, 2, and 3 respectively. V C The addition amount is 1=100mg / kg, 2=200mg / kg, 3=300mg / kg, V E 1=100mg / kg, 2=200mg / kg, 3=300mg / kg, soybean oil is 1=10g / kg, 2=20g / kg, 3=30g / kg. According to the orthogonal test design, the 4th to 12th groups are different doses of V E , V C The combination of soybean oil and soybean oil is shown in Table 1; the 13th group is the blank control group (basic diet group). The trial started on August 1, 2014 and ended on September 15, and lasted for 45 days. The feed for laying hens is provided by Nantong Zhengda Feed Co., Ltd., ...

Abstract

The invention discloses a layer feed additive capable of increasing the egg yield in high-temperature seasons. The additive is composed of rosemary powder, VC, VE and soybean oil. 3.0-9.0 g of the rosemary powder, 100-300 mg of the VC, 100-300 mg of the VE and 10.0-30.0 g of the soybean oil are added in each kilogram of layer feed. When the highest temperature in a chicken house exceeds 30 DEG C, optimized VE, optimized VC, optimized soybean plant oil and optimized natural antioxidant rosemary in different proportions are added in layer feed in the laying period of layers, and accordingly the egg yield of the high-yield layers and the egg quality are improved, the shelf life of eggs is prolonged, and layer feed incoming and laying performance are remarkably improved.

Description

Technical field [0001] The invention relates to the field of feed for poultry production, in particular to a feed additive for laying hens that can increase egg production in high-temperature seasons. Background technique [0002] The high temperature and high humidity in summer in southern my country are extremely unfavorable for poultry production. This is because the range of body temperature of chickens is 40~41℃, but the environment temperature of high laying hens during laying period is 13-16℃, the egg production rate is the highest, and the feed rate of 15-20℃ is the best. When the highest temperature in the house exceeds 30℃ It will cause the chicken body to produce a series of adverse reactions both physically and mentally. Heat stress will reduce the feed intake, nutrient digestibility, egg production rate, egg weight, Huff units and egg yolk index of poultry. The main reason is that heat stress will cause the release of adrenerone and catecholamines and promote cell m...
