Description

  The present invention relates to a vegetable oil for feed, a feed for livestock and poultry using the same, and a method for raising livestock and poultry.

Vegetable oil oil is extremely useful as an animal feed material because it is inexpensive and has high nutritional value. Examples of feeds mixed with vegetable oil syrup for feed include, for example, feeds with low viscosity vegetable oil syrup added with a viscosity reducing agent added to vegetable oil syrup (Patent Document 1) and grease-like neutralized soda oil syrup. Formulated feed (Non-patent Document 1) and the like have been reported.
However, the vegetable oil oil for feed used so far has poor viscosity due to its high viscosity, and its high water content leads to feed deterioration and spoilage, and there is still a feed that is still sufficiently satisfactory in terms of productivity. The actual situation was not obtained.

  The present invention has been made in view of the conventional problems and circumstances as described above, and is excellent in handleability, and can be improved in feed efficiency for livestock and poultry and can improve productivity. It is an object to provide a livestock / poultry feed used and a method for raising livestock / poultry.

  As a result of intensive studies to solve the problem, the present inventor has improved the feed requirement rate of livestock and poultry and improved the breeding performance by using vegetable oil for feed containing a specific amount of water and sodium fatty acid. It was found that the decrease in productivity and the decrease in productivity could be prevented, and the present invention was completed.

  That is, this invention solves the said subject with the vegetable oil oil for feed characterized by having a water content of 3 to 35% by mass and a fatty acid sodium content of 5 to 30% by mass.

  Moreover, this invention solves the said subject with the feed for livestock and poultry characterized by containing the said vegetable oil gypsum for feed.

  Moreover, this invention solves the said subject by the breeding method of the livestock and poultry characterized by feeding the said feed for livestock and poultry.

  According to the present invention, feed efficiency of livestock and poultry can be increased, and an excellent productivity improvement effect can be obtained. Further, when preparing the feed, the vegetable oil for feed can be uniformly mixed, and a feed with a constant quality can be obtained.

  In the vegetable oil syrup for feed of the present invention, the oil syrup separated from the vegetable oil crude before refining in the deoxidation step in the vegetable oil refining step is dried to have a moisture content of 3 to 35 mass% and a fatty acid sodium content of 5 It is obtained by adjusting to the range of ˜30% by mass. The oil used here is neutralized by adding phosphoric acid and caustic soda to vegetable oil crude oil and removing the refined vegetable oil by centrifugation, etc., and adding sulfuric acid to this soda oil. And a neutralized oil cake obtained by adding an acid oil cake obtained by further adding sulfuric acid or the like.

  The vegetable oil crude oil may be any raw material as long as it is approved for use as an edible oil and fat. For example, rapeseed oil crude oil, soybean oil crude oil, linseed oil crude oil, safflower oil crude oil, sesame oil crude oil, rice Oil crude oil, cottonseed oil crude oil, sunflower oil crude oil, palm oil crude oil, Kapok oil crude oil and the like are preferable. Rapeseed oil crude oil and soybean oil crude oil are particularly desirable.

  There are no particular limitations on the method of drying the oil cake that adjusts the water content and the fatty acid sodium content, and examples include hot air drying, freeze drying, and spray drying.

  In the present invention, when the moisture content contained in the vegetable oil oil for feed is more than 35% by mass, for example, when this is used as a feed raw material, it is easily altered and spoiled particularly at high temperatures (summer season, etc.) On the other hand, when the water content is less than 3% by mass, the viscosity becomes high, so that it is difficult to uniformly mix with the feed, which is not preferable from the viewpoint of handleability. The water content in the vegetable oil for feed is preferably 3 to 35% by mass, particularly preferably 5 to 30% by mass, and more preferably 7 to 20% by mass.

Moreover, when the fatty acid sodium content contained in the vegetable oil oil for feed is more than 30% by mass, the fluidity and growth performance of the vegetable oil oil for feed deteriorates, and on the other hand, when the fatty acid sodium content is less than 5% by mass, Not only does the growth performance worsen, but the amount of vegetable oil oil for feed added to the feed increases, moisture in the feed increases, and it tends to rot. 5-30 mass% is preferable and, as for the fatty-acid sodium content in the vegetable oil oil for feed, 10-25 mass% is especially preferable.
The fatty acid in the fatty acid sodium is a fatty acid obtained from vegetable oil, but includes both saturated fatty acids and unsaturated fatty acids. For example, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, enanthic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, erucic acid, linoleic acid, linolenic acid, etc. Is mentioned. The fatty acids may be single or mixed fatty acids.

  In this invention, it adjusts so that it may contain 0.2-5 mass%, preferably 0.4-2 mass%, and sodium 1-15 mass%, preferably 2-10 mass% of phosphorus in the vegetable oil oil for feed. Thus, when this is used as a feed raw material, the productivity improvement effect can be further enhanced. Further, from the viewpoint of energy utilization, the content of phospholipid (phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine) is preferably 10% by mass or less in the vegetable oil oil for feed.

In the present invention, the contents of water, fatty acid sodium, sodium, phosphorus, and phospholipid in the vegetable oil for feed can be quantified by the following method.
Moisture measurement method described in "Explanation of the 5th edition Japanese food standard ingredient table analysis manual written by analytical practitioners" (Chuo Hoju Publishing Co., Ltd., July 15, 2002, first edition, second edition, pages 12-14) It is measured based on the drying assistant addition method.

Measuring method of fatty acid sodium Fatty acid sodium fraction is determined from the following acid-decomposed crude fat method and ether extraction water washing method.
