Formulated feed for laying hens of 4-10-week-old brooding period and preparation method thereof

Abstract

The invention discloses a formulated feed for laying hens of 4-10-week-old brooding period. The formulated feed comprises the following raw materials of: by weight, 47.22% of corn, 15% of wheat, 23.11% of soybean meal at CP43%, 3.0% of rapeseed cake, 0.5% of rice oil, 7.22% of solvent rice bran meal, 0.94% of calcium hydrogen phosphate, 1.52% of stone flour, 0.38% of 65%lysine, 0.16% of solid methionine, 0.06% of threonine, 0.1% of choline, 0.05% of Maxus premix, 0.32% of salt, 0.01% of liquid wheat enzyme, 0.01% of liquid phytase, 0.2% of a composite premix for laying hens and 0.2% of a poultry mineral premix. A preparation method of the formulated feed provided by the invention comprises the following steps of: weighing all the raw materials according to the above weight percentage, putting the raw materials into a pulverizer for crushing until the crushing granularity reaches 20-30 meshes; pouring into a granulator while the granulation temperature is 75-80 DEG C and the gelatinization degree is greater than or equal to 90%; and crushing until the crushing granularity reaches 8-15 meshes. The formulated feed provided by the invention can be used to satisfy the nutrition demand of laying hens, guarantee the body weight of chicken reaches the standard and raise the uniformity of chicken.

Description

technical field [0001] The invention relates to a compound feed for feeding in the brooding period of laying hens, in particular to a compound feed for 4-10 weeks old in the brooding period of laying hens and a preparation method thereof. Background technique [0002] Brooding is a key stage in the entire laying hen production cycle. The growth and development of chicks is directly related to the uniformity and egg production rate of the bred chickens, thus affecting the production performance of the hens. Studies have shown that body weight at 5 weeks is positively correlated with precocity (ie, daily egg production rate at 20-24 weeks), with a correlation coefficient of 0.63; it is positively correlated with egg laying persistence, with a correlation coefficient of 0.82; and survival at 60 weeks old. The rate was positively correlated, and the correlation coefficient was 0.71. Egg chicks moult for the first time at 4-10 weeks of age. At this stage, chicks grow and develop...

Problems solved by technology

[0003] The disadvantage of traditional chick feed is that it is not suitable for the nutritional needs of layer chicks

The digestibility of chicks is weak, and the utilization rate of oil and fat is poor. During the production process of traditional chick feed, the above-mentioned problems have not been considered in terms of raw materials and production technology; some farmers use 21% crude protein chicken feed. There is a big problem with this feeding method: broiler chicks are high in protein and energy, and are designed for fast-growing broiler chickens. If they are used in laying hens, they will not adapt to the development of their cardiovascular system and are not conducive to the growth of laying hens. Nutrition and metabolism diseases will also occur during the body size development stage; at the same time, due to the extensive selection of raw materials and non-standard production processes, the digestibility of traditional laying chicken powder is low, the hygiene indicators are poor, and the feed intake is uneven, which cannot meet the requirements of laying chicks at the stage of laying chickens. Nutrient requirements, which ultimately affect the performance of laying hens throughout the production cycle
