Problems solved by technology

[0002] In order to meet the energy demand of broiler chickens and ensure their growth performance, the energy level of ordinary broiler chicken feed usually reaches 3.15Mcal / kg, which leads to an increase in feed costs and reduces the economic benefits of farmers
Moreover, high-energy feeds also lead to a large amount of abdominal fat deposition in broilers, which reduces the quality of broiler carcasses.
At the same time, large broiler chickens consume a lot of food and excrete a lot, which pollutes the environment to a certain extent.

Abstract

The invention relates to the field of animal feed, and particularly relates to a low-energy feed for meat chicken, which is composed of corn, bean pulp, mixed enzymolysis pulp, wheat flour middling, dried corn distiller's grains, stone powder, table salt, lysine, methionine, threonine, tryptophan, choline, emulsifying agent, organic acid, enzyme preparation and 0.5% of premix. The energy level ofthe feed is 2.8-2.9Mcal / kg and is lower than the energy level 3.15Mcal / kg than common meat chicken, and the feed is suitable for meat chicken with age of 35 days to fence leaving time. According to the feed provided by the invention, by improving the digestion and absorption of fat and fat-soluble nutrient substances and the energy conversion efficiency, the growth performance of the meat chicken, the feed conversion rate, yield of carcass and chicken quality are guaranteed, and the purposes of lowering the feed cost, improving economic benefits, reducing the discharge of livestock and poultry feces and reducing environmental pollution are achieved.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a low-energy feed for broiler chickens and a preparation method thereof. Background technique [0002] In order to meet the energy demand of broiler chickens and ensure their growth performance, the energy level of common broiler chicken feed usually reaches 3.15Mcal / kg, which leads to increased feed costs and reduces the economic benefits of farmers. Moreover, high-energy feed also causes a large amount of abdominal fat deposition in broilers, which reduces the carcass quality of broilers. At the same time, large broiler chickens consume a lot of feed and excrete a lot, which pollutes the environment to a certain extent. Contents of the invention [0003] The purpose of the invention is to provide a low-energy feed for large broilers [0004] The object of the present invention is also to provide a preparation method of low-energy feed for broiler chickens. [0005] To achieve th...
