Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for raising calves using a heat-retaining mat.

In pig farms, it has traditionally been common practice to raise pigs in a warm environment, but these animals are naturally resistant to cold, and keeping them warm can actually increase the number of pathogens in the cowshed.
Since calves are being bred for 100 liters, calves are not kept warm, and the inside of the cow shed is heated only by the body heat of the cows even in the cold season.
The reality is that K is kept to a level of ℃1.

On the other hand, diarrhea is a major hindrance to the growth process of calves, and when contracted, most of the calves die, or even if the calves are saved, the milk production decreases and problems remain. Therefore, special attention must be paid to diarrhea when raising calves.

In view of the above-mentioned circumstances, the inventor of the present application has conducted intensive research on a method for overcoming the problem of diarrhea and growing calves smoothly, and has found that calves are born contrary to the conventional wisdom that calves should be raised in cold conditions. For calves that are less than one month old, we have found that placing a heat-retaining mat in the cow shed to raise them is an extremely effective solution to problems such as diarrhea.

The calf that is the object of this invention is a newborn calf within one month of birth. These calves drink powdered milk for about 3 days after calving.
Excrete the meconium and then drink whole milk or milk replacer 3 to 1
Calves are fed for 2 weeks, or fed with whole milk for 3 to 5 weeks, then skimmed milk, and fed with weaning starter and hay ad libitum. It is important to include a heat-retaining mat as in this invention.

For example, the heat retention mat should be 800% to 1000% vertically and 5% horizontally.
A rubber material with a thickness of about 00 to 600 A heat insulating plate 3 is inserted into the lower surface of the plate, and a planar heating element is inserted between the heat dissipating plate and the heat insulating plate 3.

The conical heating element is made of a material that has a self-temperature control characteristic that automatically changes its capacity in response to temperature changes inside the cow, rather than the conventional one equipped with a temperature control device such as a thermostat. It is preferable to use heated heaters (commonly sold under the trade name Surlyn Heat), which are made of a film of ionomer resin specially inscribed with carbon black. Since the ionomer contained inside has a property that the capacity decreases when the ambient temperature is low, the temperature is always maintained at the set value.

The surface temperature of the heat retaining mat is in the range of 50 to 42°C, preferably around 58°C. Note that if the surface temperature is below 50°C, there is no effect, and if the surface temperature is above 42°C, there is a risk of low-temperature burns if used for a long period of time.

Please note that the appropriate period of use for the heating mat is 5 days to 1 hour, but if you use it for a long period of time, bacteria may grow on the heating mat, so please wash it thoroughly before use. The better the better.

In addition to the use of heat-retaining mats in the cold winter season, it is also effective to use them during the cold autumn season, etc.

Examples of this invention will be shown below.

Example (1) Heat retention mat size: 100OXX 600XX 11% electricity dissipation crab Ae 100V 125W Rubber; PC mat weight: 8.5 to 4 Planar heating element with self-temperature control property inside (product name Surlyn Heat) The surface temperature of the heat-insulating mat was set at 58°C.

(2) Target calves The growth status of calves calved at the Icefield Farm was tested for calves that were calved using heat-retaining mats during the cold season from January to February, and those that were not used heat-retaining mats.

The results of this test are shown below: (3) Results and Discussion As is clear from the above results, in the cultivation method using heat-retaining mats, the daily increase in salary was in the 500 f range in all five cases. This shows that even if diarrhea occurs, it heals within a day and the growth is normal.

On the other hand, when the heat insulating mat was not used, the diarrhea continued for 4.5 days and the daily weight gain was in the 100 f range.

In addition, Figure 2 shows the changes in the surface temperature of the heating mat and the temperature inside the cowshed over time, and as is clear from this figure,
When using the heat insulating mat according to the present invention, there is little change in the surface temperature of the heat insulating mat and the temperature inside the cowshed over time, and the temperature can be maintained approximately at the set value, and the temperature is uniform no matter where on the surface of the heat insulating mat. This brings about excellent results in raising calves. On the other hand, depending on the place where a temperature control device such as a thermostat is installed as in conventional heating mats, the heater may operate inappropriately (9) or may not operate, resulting in the surface temperature of the heating mat not being constant.
Poor results in calf development.

In addition, according to this invention, since a sheet heating element is inserted inside the heating mat, the heating area is extremely large compared to the case where a conventional linear heating element is inserted with a chrome wire, an electric heating hotbed wire, etc. Furthermore, the heat-retaining mat used in this invention has self-temperature control characteristics, consumes less power, and is economical.

In addition, according to the breeding method of the present invention, since the amount of weight gain on -day is large, the consumption of substitute energy is less than in the conventional method, and as a result, the efficiency of feed utilization is increased.
