Regarding the estimation rule that was made possible.

[0002]

2. Description of the Related Art Beef cattle breeds that produce high-quality beef traded under brands such as Kobe beef and Maesawa beef are "Kuroge Japanese breeds". At the production site, steers that castrated males are fattened. The start of "fat" to increase the nutrient concentration to improve the growth and to accumulate fat properly is to start from 9 months of age (300 kg body weight) to 28 months of age (700 kg body weight). Continues to 33 months of age. Since the feed consumption per cow will be 3 tons or more during the entire fattening period, the key to efficient fattening management will ultimately be whether an adequate amount of feed that meets the nutritional requirements of beef can be fed without waste. Become.

The nutritional requirement required for growth is calculated from the body weight, so it is important to know the body weight. However, the weight scale for cattle has sufficient holes by digging holes for accommodating a large scale in the installation ground. Most of the production sites do not have weight scales because it costs money not only to install the main unit but also to install it to obtain strength. For this reason, there has been almost no means of knowing the weight at the fattening site. Even if there is a scale, it is not easy to move each cow from the fattening barn to the scale.

As described above, there is almost no weight scale at the production site of beef cattle, and the growth condition of fattening cattle can be determined only by visual estimation. That is, the amount of feed to be fed was estimated based on visual information. In order to achieve economically efficient fattening, it is necessary to have a means to accurately and easily estimate the growth rate and nutritional requirements of cattle.

[0005]

In most cases, there is no weight scale at the production site of beef cattle, and the growth condition of fattening cattle can be estimated only by visual estimation. The amount of feed is also estimated based on visual information. In order to carry out fattening with high economic efficiency, it is necessary to have a means to accurately and easily estimate the growth rate and nutritional requirements of cattle.

[0006]

[Means for Solving the Problems] Therefore, repeated studies were conducted to estimate the weight easily by some means, and the weight of Japanese Black steers was measured once a week for about 10 years, and once a month. The body size of 11 sites was measured, and it was found that there was a high correlation between chest circumference and body weight, and the present invention was completed.

Chest circumference and body weight of Japanese Black steers show a highly significant correlation (third regression). From this relationship, a "weight scale" that can be easily used for weight estimation at a fattening site can be created, and the weight of fattening cattle can be estimated using the "weight scale" of the present invention.

Since the nutritional requirement is expressed as a function of the 0.75th power of the body weight, the "nutrition requirement scale" can be scaled,
Using this, the nutritional amount required (based on TDN),
You can know the actual amount of concentrated feed to be fed.

According to the present invention, it becomes possible to easily know the growth condition and the nutritional requirement on a daily basis at the production site of fattening cattle, it becomes possible to feed the feed properly without waste, and improve the economic efficiency in fattening management. Can be achieved.

The present invention is characterized by having the following constitutions as described in claims 1 to 5. A. Chest circumferences of Japanese black castrated fattening cattle having a fattening period of 9 months to 28 months were measured by a tape-like scale, and the weight of the fattening cattle was calculated from a regression equation showing a highly significant correlation with the body weight or 0. The nutritional requirement of the fattening cow obtained from the function of the 75th power or the amount of concentrated feed to the fattening cow calculated based on the body weight of the energy to be fed is estimated.

B. On the tape-like scale, a scale of estimated body weight was attached at a position corresponding to the scale of the chest circumference. C. On the tape-shaped scale, a scale of estimated nutritional requirement was attached at a position corresponding to the scale of the chest circumference.

D. On the tape-like scale, a scale for the estimated concentrated feed amount was attached at a position corresponding to the scale on the chest circumference. E On the above tape-like scale, the scale of estimated body weight, the scale of estimated nutritional requirement, and the scale of estimated concentrated feed supply were written together at the position corresponding to the scale of the chest circumference.

[0013]

Function: A. By measuring the chest circumference of the fattening cow with a tape (tape measure) scale, the weight of the fattening cow, the nutritional requirement, and the amount of the concentrated feed to be fed are simple.
And easily guessed.

The above B. With this configuration, the scale of the estimated weight can be read by simply measuring the chest circumference of the fattening cow with a tape (tape measure) scale for measuring the chest circumference of the fattening cow, and the estimated weight can be easily and quickly known. The above C. By measuring the chest circumference of fattening cattle, by measuring the chest circumference of fattening cows with a tape (tape measure) scale, the scale of estimated nutritional requirements can be read and the estimated nutritional requirements can be easily and quickly determined. .

The above D. By measuring the chest circumference of fattening cattle by measuring the chest circumference of fattening cattle by measuring the chest circumference of fattening cattle, the scale of the estimated concentrated feed amount is read, and the estimated concentrated feed amount is simple and quick. I understand. The above E. By measuring the chest circumference of fattening cattle, by measuring the chest circumference of fattening cattle with a tape-shaped scale, the scale of estimated body weight, the scale of estimated nutritional requirements, and the scale of estimated concentrated feed supply are read. Therefore, the estimated weight, the estimated nutritional requirement, and the estimated concentrated feed amount can be easily known at the same time.
