Abstract

PURPOSE:To obtain the title feed having high absorption rate, hardly having accumulating properties, oxidizable in lever, consumable as energy, containing a middle-chain fatty acid triglyceride. CONSTITUTION:The objective feed containing 8-12C a middle-chain fatty acid triglyceride (MCT).

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a fattening feed for meat livestock, and more specifically, a nutritional effect that improves the weight gain and meat quality of meat livestock during the growth period, and an effect that improves feed efficiency. The present invention relates to a fattening feed for meat and livestock having the following properties.

[Conventional technology and its problems]

In recent years, compound feeds for meat livestock have tended to be concentrated feeds designed to be high in protein and high in calories, with the aim of increasing feed efficiency and weight gain. However, feeding such concentrated feed causes great physiological stress on meat animals, putting a strain on the liver, which plays an important role in physiological functions, causing enlargement of the liver and abnormal accumulation of lipids, which has a negative impact on the animals. affect In addition, such fattening feeds contain large amounts of animal fats and oils as an energy source, and although these additions improved body weight gain, they also increased back fat and body fat. These fats have a significantly lower commercial value than muscle, and fat deposits in the horns mean wasted feed energy, so fatty carcasses are a cause of lower economic value.

In order to solve these problems, methods such as reducing the amount of added fats and oils and administering drugs, feed additives, etc. are being considered, but the problems have not been solved yet.

[Means to solve the problem]

The present inventors conducted intensive studies to improve the above problems, and found that by feeding growing livestock with fattening feed containing medium-chain fatty acid triglyceride with 8 to 12 carbon atoms as an essential component, The present inventors have discovered that it has excellent effects on improving abnormal fat accumulation, as well as improving nutrition, feed efficiency, and productivity, and have completed the present invention.

That is, the present invention provides a fattening feed for meat and livestock that is characterized by containing medium chain fatty acid triglyceride (hereinafter referred to as MCT) having 8 to 12 carbon atoms.

The fattening feed for meat and livestock of the present invention can be given as a solid (granular) or as an aqueous solution (liquid feeding). Moreover, the feed of the present invention is particularly suitably administered to meat pigs and beef cattle.

The fatty acid composition of MCT used in the present invention is generally 50 to 100% by weight of caprylic acid having 8 carbon atoms, 0 to 50% by weight of capric acid having 10 carbon atoms, and 0 to 50% by weight of stearic acid having 12 carbon atoms, Other fatty acids are present in trace amounts.

However, long-chain fatty acids may be contained as long as they do not impair the effects of the present invention. - As the MCT used in the present invention, commonly available commercially available MCTs such as Coconart MT and Coconart RK (trade name, manufactured by Kao Corporation) can be used.

The absorption system for MCT used in the present invention is the lymphatic system for conventional long chain fatty acid triglycerides (LMT).
Since it is carried out in the portal vein system, it is absorbed quickly and has the characteristics that it does not accumulate and most of it is oxidized in the liver and consumed as energy.

The amount of MCT added in the fattening feed for meat livestock of the present invention is 0.
．． 5% by weight or more, preferably 1.0-15% by weight for pork
, in the range of 1.0 to 10% by weight for beef cattle.

So far, feeds containing MCT have been shown to be effective in preventing diarrhea during the chewing period (Japanese Patent Application Laid-Open No. 2-100
No. 635) and one showing anti-disease effects for fish farming (Japanese Patent Application Laid-Open No. 2-35048) have been disclosed. However, in these cases, palatability becomes extremely low because MCT is contained at a relatively high content.

On the other hand, the fattening feed for meat livestock of the present invention has a relatively low MCT content, so palatability is not impaired, and when given to meat livestock in an appropriate amount, it can increase the salary of meat livestock and improve meat quality. It is something that can be done.

Traditionally, fattening feed for meat and livestock uses corn as the main ingredient.
Cereals such as milo and soybean meal are used, and nutritional materials such as oils and fats, sugars, proteins, vitamins, and minerals are used as other ingredients.In the present invention, the above-mentioned MCT is used as a substitute for oils and fats. , the object of the present invention can be achieved by adding it as a new component.

In the present invention, meat livestock refers to cows that have finished feeding milk replacer and are at the end of fattening, with a weight of 70 kg or more that allows them to eat enough roughage, and pigs that have finished feeding on artificial milk after weaning. The term refers to those with a weight of 20 kg or more at the end of fattening.

〔Example〕

EXAMPLES Next, the present invention will be specifically explained with reference to Examples, but the present invention is not limited to these Examples.

Example 1 20 growing pigs with an average weight of 35 kg were divided into 4 groups of 5 pigs each, and fed with a feed composition as shown in Table 1 for 3 months.
A survey was conducted on final body weight, pay increase, feed conversion ratio, and back fat thickness in each group.

Here, the feed conversion ratio is feed intake (g) / weight gain (g)
I asked for it.

As shown in Table 2, the test plots fed the feed of the present invention had improved pay increase, feed conversion ratio, and backfat thickness compared to the comparison plots. Note that each value in Table 2 is an average value of five animals.

Table 1 Note) *TG; Triglyceride Table 2 Note) *Average of three parts of the back Example 2 Six Holstein steers with an average weight of 90 kg were divided into 3 groups of 2, and concentrated alfalfa hei cubes were fed as roughage. The animals were fed a feed with the formulation shown in Table 3 for 14 weeks, and the increase in salary and blood properties related to cholesterol, phospholipid, and triglyceride were investigated.

The results are shown in Table 4, as compared to the comparison group, the test group fed the feed of the present invention had improved pay increase, and lipid metabolism was also improved based on blood properties. In addition, each value in Table 4 is an average value of two animals.
