Embodiment Construction

[0026] Get 66 kilograms of corn flour, 25 kilograms of urea, 5 kilograms of bentonite, 2 kilograms of brown sugar,

[0027] 1 kg of soybean flour, crushed separately, so that 60-80% of corn flour and urea can pass through a 40-mesh analytical sieve, according to the above formula requirements, mix the raw materials evenly in proportion, with a water content of 18-22%, and send them into the extruder Expanding in the machine, the pressure is 1.0-1.5Mpa, the temperature is 150°C, after expansion, it is cooled and crushed to make slow-release non-protein nitrogen.

Abstract

A slow-releasing non-protein nitrogen feed for domestic animals and fowls is prepared from corn flour, urea, bentonite, brown sugar and soybean through pulverizing, proportionally mixing, puffing, cooling and breaking. It features that the urea particles are wrapped by starch membrane to elongate its hydrolyzing time to 3-4 hr, so preventing poisoning.

Description

Technical field: [0001] The invention belongs to the technical field of livestock and poultry feed formulations and production techniques, in particular to a feed formulation for ruminants and a production technique for producing the feed. Background technique: [0002] With the progress of society, the development of science and technology and market demand, the production of fattening beef cattle and other ruminant livestock must transition from the original natural extensive feeding to large-scale feeding. Feed is the main feed. In order to save food, stabilize feed nutrition and reduce feed cost, people currently use protein supplement feed—urea as ruminant feed, but at the same time, urea feed is easy to cause ammonia poisoning and has a low utilization rate. Invention content: [0003] The technical problem to be solved by the invention is to disclose a slow-release non-protein nitrogen feed that can prevent animal poisoning and improve utilization rate and a process...
