The Total Mixed Diet (TMR) is based on the nutritional needs of beef cattle at different growth and development stages. According to the diet formula designed by the nutrition experts, the roughage, green fodder, silage and concentrate supplements are fully scaled with a special blender. A balanced, balanced nutritional feed that is agitated, cut, and mixed.
principle
1.1 pay attention to palatability and satiety
The beef cattle diet must be formulated with the palatability of the feed ingredients to ensure the feed intake of the beef cattle. At the same time, it is necessary to take into account whether the beef cattle can have a feeling of fullness and meet the needs of the maximum dry matter intake of beef cattle.
1.2 meet nutritional needs
Beef cattle fully mixed diets should be prepared in accordance with the standards for beef cattle breeding and fully consider the actual production level. According to the nutritional needs of a certain weight and the expected daily weight gain, the feeding amount can be higher than the breeding standard by 1% - 2%, but should not be excessive.
1.3 The ratio of fine to is appropriate
The proportion of refined roughage in beef cattle diets varies according to the quality of the roughage and the physiological stage of the beef cattle and the fattening period. It should be ensured that neutral detergent fiber (NDF) accounts for 28% of the dry matter of the diet. The NDF of the roughage accounts for more than 21% of the dry matter of the diet, and the acid detergent fiber (ADF) accounts for more than 18% of the diet.
1.4 Variety of raw materials and varieties
The variety of raw materials for beef cattle diet should be diversified, not too monotonous, and a variety of feeds can be used to facilitate nutritional balance and full price. Local forage resources should be fully utilized to reduce feeding costs.
1.5 feed composition remains stable
Avoid sudden changes in the composition of the diet, causing rumen microbes to adapt, thereby affecting digestive function and even leading to digestive tract diseases. The feed used should be clean and hygienic, and all kinds of feed should be specified in the range of dosage to prevent the use of feed containing harmful factors.
2 production technology
2.1 full mixed diet design
2.1.1 Determine nutritional needs. According to the beef cattle group (according to the physiological stage and production level), body weight and sensation, etc., based on the beef cattle breeding standards, the nutritional needs of beef cattle are appropriately adjusted. According to the nutritional needs, determine the nutritional level of TMR, predict its dry matter intake, and properly prepare beef cattle diet.
2.1.2 Determination of feed ingredients and their composition. According to the resources of local forage feed, choose high quality and low price raw materials. Raw material crude protein, crude fat, crude fiber, moisture, calcium, total phosphorus and coarse ash should be determined according to relevant standards.
2.1.3 Formulation design. According to the determined beef cattle TMR nutrition level and selected feed ingredients, the composition and feed value of the feed ingredients are analyzed and compared, and the most economical feed formula is designed.
2.1.4 Dietary optimization. Under the premise of meeting nutritional needs, the pursuit of dietary costs is minimized. The maximum dry matter of concentrate supplements should not exceed 60% of the dry matter of the diet. Ensure that the dietary degradation protein (RDP) and non-degradable protein (UDP) are relatively balanced and appropriately reduce dietary protein levels. When adding high-energy feeds such as protective fats and oilseeds, the dietary fat content (dry matter basis) should not exceed 6%.
We supply various Mosquito Killing Lamp, including mosquito killing bulb, mosquito killer machine.
The below information will help you to know more about Solar Light.
Does mosquito killer lamp work?
Bug zappers work by emitting a UV light that attracts bugs to the center of the device, where they're electrocuted, usually between two metal grids. Because of the irresistible lure of their light, bug zappers are incredibly effective at killing bugs.
Is mosquito lamp harmful to humans?
UV light from bug zappers will not harm you or your family as they are not hazardous. That is why bug zappers are placed high up in homes to catch more insects and present absolutely no harm to humans.
Where do you place a mosquito lamp?
1. Place the Trap between the mosquito source and areas of human activity.
2. Place the Trap as far away from people (20-30 ft) and as close to the mosquito source as possible. (Attract them to the Trap and not to you)
Do mosquito lamps work during the day?
Yes, the unit will continue to attract and kill insects 24 hours a day.
