Reasonable light time and light intensity are beneficial to the growth and development of beef cattle, promote metabolism, increase the demand for food, and are beneficial to the improvement of meat production performance and other aspects.
Sufficient light time and intensity are helpful for beef cattle to withstand the severe cold. In summer, when the temperature is higher, the light time and intensity are larger. At this time, attention should be paid to the heatstroke prevention of beef cattle.
Beef cattle are more sensitive to temperature changes, so temperature has a greater impact on beef cattle. It not only affects the physical health of beef cattle, but also has a certain effect on their meat production capacity.
Research shows that when the ambient temperature range is between 5 and 20°C, beef cattle grow the fastest and have the largest average daily weight gain. Both high and low temperatures are not conducive to the growth and fattening of beef cattle.
In summer, the temperature is higher than the optimal living temperature for beef cattle, which results in poor appetite of beef cattle, reduced feed intake, and relatively insufficient nutritional energy supply, resulting in slow growth, no obvious weight gain, and reduced beef quality. In addition, high temperature is conducive to the growth of microorganisms. During growth and reproduction, the number of microorganisms in the cattle shed increases and the activities are frequent, which increases the chance of beef cattle being infected and increases the chance of beef cattle getting sick.
In winter, the temperature is lower than the optimal living temperature for beef cattle, and the digestion and utilization rate of feed by beef cattle is reduced. At this time, in addition to maintaining normal physiological activities, part of the heat energy generated by consuming feed is also needed to maintain a constant body temperature of the beef cattle. Therefore, it is The increased demand for feed increases the cost of raising beef cattle.Therefore, it is necessary to prevent heatstroke in the hot summer, and to strengthen the heat preservation of beef cattle in the cold winter.
Humidity also has a crucial impact on the health and heat production characteristics of beef cattle. It mainly affects the evaporation of water on the surface of beef cattle, which in turn affects the heat dissipation of the beef cattle's body.
Affects beef cattle's ability to regulate heat. The greater the humidity, the lower the beef cattle's ability to regulate body temperature. Coupled with the high temperature, the water on the body surface of the beef cattle cannot volatilize normally, and the heat in the body cannot be dissipated. The heat accumulates, the body temperature rises, the normal metabolism of the beef cattle is blocked, and in severe cases, it can cause the beef cattle to suffocate. And die.
Airflow mainly affects the indoor air flow, thereby affecting the temperature, humidity and the flow of beef cattle body heat in the barn. It indirectly affects the health and meat production of beef cattle and may cause cold stress in beef cattle, which is not conducive to the rapid growth of beef cattle.
Therefore, the air flow rate must be reasonably controlled. In addition, the flow of air can also speed up the timely elimination of harmful gases, create a good air hygiene condition, improve the utilization and conversion rate of feed, which is conducive to the rapid growth of beef cattle, and also plays a certain role in improving the meat quality of beef cattle. enhancement.
