Abstract
The invention provides a feed additive special for experimental rats. As the required amount of rat digestible feed is about 15.9MJ/kg, rat feed is based on powder. Specifically, water is added into well blended dry powder, and they are mixed uniformly, then the formed mixture is subjected to steam pressurization shaping treatment, thus obtaining the feed. 0.36% of methionine or 0.5% of lysine is added into the feed to make rats reach a fastest growth speed. After a growth period, the protein requirement drops sharply, and 7%-10% of protein can meet the maintenance needs of adult rats. In view of rats at the growth period are likely to suffer fatty acid insufficiency, the fatty acid in the feed should account for 1.3% of thermal energy substances, wherein linoleic acid is not be less than 0.3%.
Description
Technical field
The present invention relates to a kind of feed addictive, relate in particular to a kind of experimental rat feed addictive.
Background technology
Rat is animal used as test the most frequently used in the life science, and its use amount accounts for 80% of all experiments were animal consumption.
Though rat is Omnivore, also very strong to cellulosic digestion power, a large amount of microorganisms are arranged, energy decomposition of cellulose, synthetic B family vitamin and vitamin K in its caecum.Rat is responsive to nutritional deficiency, and the requirement of digestible energy is about the 15.9MJ/kg feed.Rat has larger resistance to the shortage of calcium, phosphorus, but higher to the requirement of magnesium.The speed of growth of the remarkable rat of riboflavin deficiency meeting.TD can cause male mouse degeneration of testis and pregnant mouse fetus to absorb.Rat is very responsive to VAD, often stings the people in case lack.Rat can effectively store liposoluble vitamin and B12, makes vitamin C and satisfies it to most of needs of Cobastab by coprophagy.
Summary of the invention
The objective of the invention is for a kind of feed addictive of experimental rat special use is provided, to solve the problem of the feed additive special that present animal used as test lacks.
The present invention is used for the pellet that experimental rat is fed, and is take powder as the basis, is shaped with the dry powder poach process steam pressurized for preparing and processes and make.The protein that contains 18-20% in the feed generally can satisfy the needs of growth, gestation and lactation.The methionine of interpolation 0.36% or 0.5% lysine can make Growth in Rats speed reach the fastest in the feed.After growth period, protein requirement falls sharply, and can suitably reduce in the feed protein content to prolong its life-span.The protein of 7%-10% can satisfy the needs of keeping of adult rat.FAP easily occurs in the rat in growth period, the requirement of essential fatty acid should account for 1.3% of heat energy material in the feed, wherein linoleic acid can not be lower than 0.3%, it can be converted into arachidonic acid in the rat body, this is the main fatty acid on the cell membrane, also is the important precursor of prostaglandin.
The specific embodiment
Embodiment 1
Prepare one kilogram experimental rat feed, wherein add the protein of 18-20%, the methionine of interpolation 0.36% or 0.5% lysine are used the dry powder poach process steam pressurized shaping processing for preparing and are made this feed, can satisfy the needs of miniature pig growth, gestation and lactation.
Embodiment 2
The rats in growing period feed that preparation is a one kilogram, proportionally in feed, add protein, the aliphatic acid 1.3% of 7%-10%, add in addition linoleic acid 0.5%, it is added abundant mixing in the basal feed, enter after crushed mixer, make the additive of fine granularity.
Claims (3)
1. an experimental rat feed addictive is characterized in that being about 15.9MJ/kg because rat can digest feed requirement, so its feed take powder as the basis, is processed and made with the dry powder poach process steam pressurized shaping for preparing.
2. a kind of experimental rat feed addictive as claimed in claim 1 is characterized in that: add 0.36% methionine or 0.5% lysine in the described feed, can make Growth in Rats speed reach the fastest; After growth period, protein requirement falls sharply, and the protein of 7%-10% can satisfy the needs of keeping of adult rat.
3. a kind of experimental rat feed addictive as claimed in claim 1 is characterized in that: FAP easily occurs in the described Growth in Rats phase, and aliphatic acid should account for 1.3% of heat energy material in the feed, and wherein linoleic acid can not be lower than 0.3%.
