Fattening cattle tail root oil bag is the majority of farmers and brokers to judge the most direct way to judge the beef cattle meat rate, the tail root on both sides of the two obviously prominent bags indicate that the cow under the skin and abdominal cavity to accumulate more oil, will affect the meat rate and slaughter**, but there is a large error, only as a reference.
Fattening cattle generally do not have a high fat content before 500 kg and do not appear in oil pockets. If this phenomenon occurs,Feeding modewithFeed formulationas the main factor,Tethered fattening is more likely to have oil ladles than loose column fatteningThe early use of a large proportion of corn or the addition of a large amount of raw materials with a high oil content in the feed formula leads to excess energy and is more likely to produce oil pockets. A reasonable feed formula can effectively prevent tail root oiling.
1) During the estrus period, the cattle are restless, the bulls chase and climb across, and the distance between the male and female cow breeding areas is especially serious.
2) Cattle irritability caused by lack of food and water.
3) Cattle irritability caused by environmental stress, common stressors include noise, high temperature, high humidity, crowding, fast-moving objects, etc.
4) The herd social relations are disrupted and need to be reordered. Such as the introduction of new cattle, merging groups, changing circles, etc.
5) Itching and irritability caused by mosquito bites, parasites, etc.
1) Terrain. In order to facilitate drainage, the ground of tethered cattle is generally high in the front and the bottom in the back, and the pressure of the hind hooves is significantly higher than that of the front hooves. Moreover, the ground where the front hooves are located is not clean when the manure is removed in some cattle farms, and it is getting higher and higher with time. The greater the height difference, the greater the pressure on the hind hooves and the easier it is to become lame. It is recommended that the height difference between the front and back should not be higher than 3 cm.
2) Variety. Most of the beef cattle have well-developed hindquarters, which are large and have high pressure on the hind hooves.
3) The slaughter body is major and the breeding time is long. The slaughter weight of beef cattle gradually increases, and the storage time becomes longer, making hoof disease more susceptible.
4) Trauma. When removing feces, it is easy to bruise the hind hooves, and the wound infection causes lameness of the legs.
When fattening cattle are slaughtered, everyone is accustomed to referring to whether the neck is plump as the standard, which has a certain reason. Fattening cattle are generally fattened in the order of back, buttocks, and neck, so the neck that rises last has become the standard for slaughter. The fullness of the neck is the first need for a higher concentration of nutrients, and the second is the accumulation of timeTherefore, in the later stage of fattening, a higher amount of concentrate must be given, and there must be enough fattening time as a support.
Fattening cattle often in the late fattening stage has not yet reached the slaughter standard when the appetite suddenly decreases, feed intake decreases, and even the phenomenon of fat loss, we usually call it unable to eat, this situation mainly has the following factors:
1) Insufficient roughage in the shelf cattle stage leads to insufficient rumen filling, which will lead to a decrease in feed intake in the later stage of fattening, and the inability to eat enough dry matter, thus affecting the growth rate.
2) The proportion of refined supplements added in the fattening period is too large, resulting in long-term rumen acidosis, causing rumen papilla damage, and the number of microorganisms in the rumen decreases sharply, thereby causing a decrease in appetite and feed intake. The solution is to reduce the amount of concentrate feed, increase the amount of roughage, and use additives and other products to help restore rumen function.
The belly shape of the fattening cattle at the time of slaughter often determines the slaughter**, the larger the belly, the lower the meat yield, so everyone hopes that the waist circumference of their fattening cattle is as small as possible when they are slaughtered. In the early stage of fattening cattle, we pull the shelf to give more forage and less concentrate, so as to achieve the purpose of hanging the shelf and supporting the stomach;The amount of roughage feed in the middle and late stages of fattening cattle is basically unchanged, and the concentrate increases with the increase of body weight, especially in the 1-2 months before slaughter, the forage can be appropriately reduced and more concentrate, the same dry matter feed intake, the volume of the diet decreases and the nutrient concentration increases, and the additives and other products that regulate the rumen are used to achieve the purpose of closing the belly.
The above content is excerpted from the textHuang Zhengyong, technical director of Beijing Zemu Jiuyuan Biotechnology Research Institute, took the lead in editing and published by China Agricultural PressBooks on breeding techniques——"100 Questions and Answers on Beef Cattle Breeding".
This book introduces more than 200 common problems in beef cattle breeding in the form of questions and answers, covering various aspects such as breed selection, feeding management, nutrition matching, breeding and fattening, disease prevention and control, pasture planning, etc., and is praised as "a practical guide to beef cattle breeding" by the majority of breeding friends.
