Feed isbeef cattleThe material basis for normal growth,Meet the nutritional needs of beef cattle production and development, metabolism and other aspects. Improving feed utilization is conducive to reducing feed costs.,Improving the Structure of Beef Cattle Metabolites,At the same time, it can improve the meat quality and production level of beef cattle. Measures to effectively improve the utilization rate of beef cattle feed are put forward.,including improved protein utilization,Improve fat utilization,Appropriate addition of minerals and vitamins,So as to effectively improve the feed utilization rate. The following specific to understand: beef cattle feed utilization factors and improve the feed intake of several methods.

1Factors Affecting the Utilization Rate of Beef Cattle Feed

genetic factors

The first factor to be considered in the impact of beef cattle feed utilization is genetic factors, because different varieties will have great genetic differences, will show different genetic traits, will also be reflected in feed utilization and other aspects. Usually special beef cattle breeds are characterized by fast growth and development, early maturity, fast daily weight gain and high feed utilization rate. China's yellow breed is a service cattle, is currently the main breed of fattening cattle in China, but compared with the special beef cattle breeds, although strong adaptability, resistance to rough feeding, and disease resistance, but other production performance, such as growth rate, feed utilization rate and so on to be relatively poor. Therefore, at present, most of the beef cattle breeds in China are hybrid offspring obtained by mating the bulls of purebred beef cattle breeds and Chinese yellow cattle breeds, and their feed utilization rate, slaughter rate and net meat rate have been significantly improved.

Age

With the growth of beef cattle age, feed intake also began to increase, daily weight gain accelerated, but feed utilization rate decreased. This is because with the growth of beef cattle age, the proportion used to maintain consumption increases, the proportion used to grow decreases, and the amount of fat increases. Therefore, this feature should be fully utilized in the process of beef cattle breeding, and sufficient nutrients should be provided during the calf period to promote the rapid growth and development of calves and increase the utilization rate of feed. At the same time, attention should be paid to the timely slaughter of beef cattle after reaching the slaughter standard, because when the weight of beef cattle reaches a certain weight, although the feed intake increases, the weight gain rate slows down, the feed utilization rate decreases, and then continue to feed, which will cause waste of feed.

dietary factors

Beef cattle are mainly fed with roughage, and the quality of roughage has an important influence on feed utilization rate. The quality of roughage, nutrition, processing methods, and the combination of concentrated feed have a direct impact on its utilization rate. Generally, the better the quality of roughage, the higher the feed utilization rate. The amount of dry matter consumed by beef cattle per day is approximately1.4%-2.7%Beef cattle of different ages and body conditions eat different amounts of feed, and the nutrient concentration requirements of the diet are also different. If the content of roughage in the diet is too much, it will affect the dry matter intake, make the energy intake level too little, and the feed utilization rate is too low, which is also not conducive to the weight gain of beef cattle. Therefore, whether the diet is reasonable or not plays an important role in the feed utilization rate of beef cattle. The research shows that with the continuous improvement of feed production and processing technology and the continuous optimization of diet structure, the feeding cycle of beef cattle is shortened on average.50-70days, the utilization rate of feed increased20%, increased weight gain25%.

Environmental factors

Environmental factors are important factors affecting feed utilization of beef cattle, and the most important factor is ambient temperature. If the ambient temperature is too high or too low, it will affect the feed utilization rate of beef cattle. If the temperature is too high, it will affect the feed intake of beef cattle, and at the same time, the amount of beef cattle to maintain consumption will increase, thus reducing the feed utilization rate. Under normal circumstances, the body weight of calves produced in winter is greater than that in summer, and the growth rate in autumn after birth is faster than that in summer, mainly because the nutritional status of cows in the late pregnancy is related to the environment. Too high or too low temperature is detrimental to the weight gain of beef cattle, thus affecting the feed utilization rate of beef cattle. In addition, if other environmental factors are not suitable, such as excessive humidity, poor air quality, and poor sanitary conditions, the feed utilization rate of beef cattle will decrease.

2Measures to Improve the Utilization Rate of Beef Cattle Feed

In order to improve the feed utilization rate of beef cattle in the process of beef cattle breeding, it is necessary to fully understand these influencing factors, so as to take effective measures to improve feed utilization rate in the process of feeding management, so as to save feed cost and improve the breeding effect.

The first step is to select good beef cattle breeds, such as the use of foreign good purebred beef cattle breeds of bulls, such as Simmental, Limucan and other local breeds of cows cross the offspring of fattening. The offspring of the hybrid has the advantages of the parent generation, such as fast growth rate, strong adaptability, high feed utilization rate, high slaughter rate, good carcass quality and so on. After selecting a good variety, it is necessary to carry out scientific breeding management. When feeding, choose high-quality and nutritious feed, pay attention to the quality of coarse feed, do not covet cheap use of inferior feed, do a good job in the preservation of feed, to avoid feeding moldy feed. Reasonable processing of roughage, the feed should be crushed should not be too short, in addition, but also for some poor palatability, low nutrient content of feed, such as straw feed for ammoniation, silage, microstorage and other processing, in order to improve the palatability of feed, nutritional value, which is necessary to improve the utilization rate of feed.In the preparation of beef cattle diet should pay attention to reasonable collocation, coarse proportion should be appropriate, according to the different growth stages of beef cattle with a reasonable diet, in order to meet the nutritional needs of beef cattle growth and weight gain. Reasonable use of compound feed, while increasingRocky Lick BrickFree licking, beef cattle need to supplement minerals,trace elementIn order to facilitate the growth and development of beef cattle.

Strengthen the daily management, do a good job of environmental control. Reasonable feeding of beef cattle should provide sufficient nutrients in the calf stage to promote the rapid growth and weight gain of calves, so as to improve the utilization rate of feed and reduce the waste of feed. Brush the cow body every day and ensure a certain amount of exercise, which can enhance physical fitness, promote metabolism, and is very helpful to improve feed utilization. Do a good job of environmental control, maintain the appropriate temperature in the enclosure, to ensure that warm in winter and cool in summer. It is also necessary to strengthen the daily cleaning work, change the bedding frequently, keep the shed dry, strengthen ventilation, keep the air in the barn fresh, and provide a comfortable environment for beef cattle.
