DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention estimates the weight, nutritional requirement, and concentrated feed supply of a fattening cow by measuring the chest circumference of a Japanese black steer with a tape-like scale such as a tape measure. It relates to an estimated scale that can be used.

[0002]

2. Description of the Related Art A beef cattle breed producing high-grade beef traded under brands such as Kobe beef and Maezawa beef is "Kuroge Wagyu". At the production site, steers are bred for steers. The start of "fattening" to increase the nutrient concentration for good growth and to accumulate proper fat starts at 9 months of age (300 kg body weight) and after 28 months of age (700 kg body weight). Lasts up to 33 months. Since the consumption of feed per cow will be 3t or more over the whole fattening period, it is ultimately necessary for efficient fattening management to be able to feed an appropriate amount of feed in line with the nutritional requirements of beef cattle without waste. Become.

Since the nutritional requirement for growth is calculated from the body weight, it is important to know the body weight. However, a weighing scale for cows has to dig a hole to accommodate a large scale on the ground where it is installed. Most of the production sites do not have weighing scales because it is expensive to install not only the main body but also the construction such as 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.

[0004] As described above, in most cases, there is no weighing scale at the beef cattle production site, and the growth of fattening cattle can be performed only by visual estimation. That is, the amount of feed to be fed was estimated based on visual information. In order to perform economically efficient fattening, means for accurately and easily estimating the growth level and nutrient requirement of cattle is required.

[0005]

Most of the beef cattle production sites do not have a scale, and the growth of fattening cattle can only be estimated by visual observation. In addition, feed supply is also estimated based on visual information. In order to achieve economically efficient fattening, means for accurately and easily estimating the growth level and nutritional requirements of cattle is required.

[0006]

From this fact, we have been studying whether it is possible to estimate the weight easily by any means, and once a week for about 10 years, the body weight of Japanese Black steers was measured, and once a month. The body measurements of 11 sites were performed, and it was found that there was a high correlation between the chest circumference and the weight, and the present invention was completed.

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

[0008] Since the nutrient requirement is represented by a function of the body weight to the 0.75th power, the "nutrition requirement scale" can be scaled.
Nutrition required using this (TDN base), furthermore
You can know the actual amount of concentrated feed to be fed.

According to the present invention, the growing condition and the nutrient requirement can be easily known on a daily basis at the production site of fattening cattle, and appropriate feed can be supplied without waste, thereby improving economic efficiency in fattening management. Can be achieved.

The present invention is characterized in that it has the following configuration as described in claims 1 to 5. A. The chest circumference of Japanese black steers with a fattening period of 9 months to 28 months was measured on a tape-shaped scale, and the weight of the fattening cow or the weight of the fattening cattle was determined by a regression equation showing a high significant correlation with the body weight. The nutrient requirement of the fattening cow, which is obtained from a function of the 75th power, or the feed amount of the concentrated feed to the fattening cow, which is calculated based on the weight of the energy to be fed, is estimated.

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

D. On the tape-shaped scale, a scale of the estimated concentrated feed supply amount was attached at a position corresponding to the scale of the chest circumference. E On the tape-shaped scale, a scale of the estimated body weight, a scale of the estimated nutrient requirement, and a scale of the estimated concentrated feed supply amount were also described at positions corresponding to the scales of the chest circumference.

FIG. 5 is a graph showing the relationship between the chest circumference and body weight of Japanese black steers for fattening cattle showing a relationship with the amount of saliva (this data was obtained at the Ministry of Agriculture, Forestry and Fisheries, Agricultural Experiment Station of the Ministry of Agriculture, Forestry and Fisheries).

As is clear from the tables shown in FIGS. 2 to 4, the chest circumference of Japanese black steers is highly correlated with body weight during the fattening period from 9 months to 28 months. Linear regression equation). The relationship between the chest circumference and the body weight (third-order regression equation) of Japanese Black steers as shown in FIG. 5 is more remarkable. The above relational expression has a significant relationship even in the first-order regression, but the third-order regression has better suitability. The tape (measurement tape) -shaped estimation scale 1 shown in FIG. 1 according to the present invention is created based on the above relational expression.

Estimation scale 1 measures the chest circumference of Japanese black steers with a fattening period of 9 months to 28 months, and calculates the weight of the fattening cow using a regression equation showing a high significant correlation with the weight, or the weight of the fattening cow. Or the actual amount of concentrated feed such as corn, wheat, barley, etc. to the fattening cattle, wherein the nutritional requirement of the fattening cattle determined from the function of 0.75 to the power of the fattening cow or the energy to be fed is calculated based on the body weight. (Concentrated feed supply amount) was created focusing on the fact that each can be estimated. The estimated scale 1 is provided with a metric scale 2 for measuring the chest circumference of the fattening cow by the metric method, and a scale (kg) 3 of the estimated weight is attached at a position corresponding to the scale 2 of the chest circumference.
Is created. In addition, it is possible to create a “nutrition requirement scale” in which a scale (Kcal) 4 of the estimated nutritional requirement is attached to a position corresponding to the scale 2 of the chest circumference. Further, it is possible to create a “concentrated feed feeding scale” in which a scale (g or kg) 5 of the estimated concentrated feed feeding amount is attached at a position corresponding to the scale 2 of the chest circumference. Furthermore, a "comprehensive estimation scale" can be created in which a scale 3 of the estimated weight, a scale 4 of the estimated nutrient requirement, and a scale 5 of the estimated concentrated feed supply amount are also described at a position corresponding to the scale 2 of the chest circumference.
