Description

A FEED METHOD OF MAKING GOOD MEAT FOR INCREASING MARBLING AND LOW CHOLESTEROL}

The present invention relates to a feed feeding method for improving meat quality of livestock, and more particularly, to a feeding method for improving meat quality by increasing marbling and low cholesterol of castrated cattle.

Recently, livestock raising has placed Korea's livestock farmers in a very difficult economic situation. To make matters worse, from 2001, imports of live imported cattle, such as Australian beef cattle and American beef cattle, will be fully open, which is expected to increase the economic impact of Korean beef farmers. Therefore, in recent years, cattle farms have been slaughtered indiscriminately in anticipation of deteriorated economic profitability. However, the most palatable and tasty meat for Koreans is meat produced from Korean beef, but if Korean beef is produced by conventional unstructured breeding methods, slaughter at 400-500kg will not be suitable for sucrose production. It is not good and is sold as cheap low grade meat and there are many problems due to lower profitability of Korean livestock farmers.

Accordingly, an object of the present invention is to provide a systematic and scientific meat quality feeding method in consideration of physiological and environmental characteristics such as age, weight, etc. of castrated cattle in order to solve the problems of conventional methods for raising unstructured Hanwoo.

1 is a block diagram of a feed method according to the present invention.

In order to achieve the above technical problem, the present invention selects a cow of good qualities capable of producing special meat, and casts it after a predetermined period of time, and then introduces, develops, develops, grows, prepares, ships, and prepares for shipment. It relates to a meat-improving feed feeding method to increase marbling and low cholesterol, characterized in that breeding through.

The configuration of the present invention will be described in detail below.

Base selection step

In the pre-breeding stage, it is very important to select seeds of excellent lineage. Among the varieties with excellent seed weight, good growth, good skin and hair quality, and healthy cows, the body height is large, but the ovum weight is larger than the height, and the fat attachment is small and the stomach pain is good. And strong paper and thick hosiery have excellent qualities.

Introduction stage

The introduction stage as the first stage of the meat quality feeding method is within approximately one month after the purchase of the calf. This is when the calf is purchased, as well as transport stress, physiologically incomplete, the period of weak defense ability with a high infection rate of diseases such as diarrhea or respiratory organs. In addition, the rumen activity is weak due to low feed intake is also the time to lose weight. Therefore, after transport, the body weight is measured, nutrients and antibiotics are administered, rice straw is fed after arrival, and water is supplied after 2-3 hours so as to adapt to a new breeding environment. Feed 500 g of feed on the day of transportation, and rice straw and alfalfa feed two to three times on the second day. And, on the 3rd to 4th day, a 500 g increase in the daily salary is applied, and the breeding method of the introduction stage of the present invention is applied until 4 months of age. In this case, rich feed is not yet available. Then, we cast off a calf that is healthy. However, calves with diarrhea do not castration.

Early stage of development

Feeding method The second stage, the early stage of growth, is 12 months after birth (approximately 300 kg), and the increase in daily gain is a high intake of rich feed and a high intake of dry matter. . However, as the absorption of rich feed increases, excessive fattening may occur. In addition, feed should be fed at an appropriate rate in consideration of the fact that the rumen development is not yet complete, and the height, height, weight, and length are less developed. Therefore, there is a need for a breeding method of limiting the weight gain per day by observing the weight every day. In order to evenly develop the rumen, internal organs, skeleton, etc., the forage-oriented specification management is performed. Therefore, in the early stages of growth, the rich feed (for upbringing) is thoroughly limited to 2.4, 2.6, 2.8, 3.2, 3.5, 3.8, 4.2, 4.5 (kg) according to the target weight and age according to the target weight. Pay a limited salary. At this time, rice straw feed is gradually increased, and as shown in Table 1, the amount is increased from 1.3 in May to 2.5 in December. In the case of alfalfa feed, it is sufficiently supplied within 1.0 to 1.2. This is the rumen, visceral, skeletal, cattle breeding method to help the development of muscle fibers.

Development stage

The third stage of feed feeding, the late stage of development, refers to 13 months to 16 months of age (approximately 300 to 400 kg). This is a period of very strong daily gains, high intake of rich feeds and high intake of dry matter. In this period, fat is intensively developed between muscles, protein, fat is actively produced, and skeletal and internal organs are rapidly developed. Therefore, at this time, it is desirable to provide a balanced feed for research and rich feeds. Therefore, as shown in Table 1, the rich feed is increased from 5.0 to 6.7 to feed, but straw straw feed is gradually reduced to 2.5 to 2.0 feed. In addition, alfalfa feed is also reduced by breeding methods from 1.0 to 0.8.

Early stages of finishing

The early stages of fattening, the fourth stage of feeding, refer to 17 to 21 months of age (approximately 400 to 550 kg). This is the most vigorous season, with the highest daily gains and dry matter intake, so the intake of rich feed is the highest. Therefore, there is a large difference in weight gain between individuals, which is the most important time for the competitiveness of beef. In addition, this time can be said that the feed replacement time to increase the rich feed while reducing the content of forage. Of course, it is also the time to change from fostering rich feeds to fat and rich feeds. Therefore, feed for improving intramuscular fat content is limited to 3.5 and 3.4 at 17 and 18 months of age, and then, after replacing the feed, the feed is continuously selected. Rich feeds are fed from 7.8 in the months to 9.3 in the 21 months. The rapid change in feed replacement may cause anorexia or diarrhea due to a drop in the acidity of the first place, so the feed should be changed slowly for at least 15 days. At this time, rice straw is gradually reduced to a limited salary from 1.5 to 1.0. In addition, alfalfa feed is gradually lowered from 0.8 to 0.5 to provide a limited salary.

Late stage

The late stages of fattening, the fifth stage of feed intake, range from 22 months of age to 3 months before shipment. This is the final stage of fat accumulation, which can lead to significant problems in the production of extraordinary back meat when undernourished. In addition, this time, as the maximum feed intake, as much as possible to produce as much meat and maximum weight as possible to feed as much rich feed as possible. Therefore, at this time, feed as much as possible to feed and at least 9㎏. In this case, rice straw will be fed one-tenth and alfalfa feeds will be stopped.

Finishing step

The finishing stage, the sixth stage of the feed benefit method, is from three months before shipment to shipment. This period should be kept in a comfortable environment, less stress and limited to a certain rich feed within 9 ㎏ care should be taken not to degrade the meat. Therefore, at the time of finishing shipment, it is necessary to mix the mixed (rich) feed and rice straw to improve fat hybridization in order to finish the meat quality, that is, to keep the meat moisturizing, juicy, high strength (marbling) and mechanical texture excellent. Do
