Second, given the "secondary" specified quantitative, due to beef cattle ruminants, the intake of food has a strong regular digestion cycle, only regular dosing can be more conducive to its growth. In summer and autumn, three times a day, each cow feeds 1.3 to 1.7 kilograms of hay per day, and the compound is 0.3 to 0.5 kilograms; in the winter and spring seasons, they are fed once a day in the morning and evening, each time they are fed 3.4 to 4 kilograms of hay, 1.5 to 2 kilograms Compound feed. Give foot water after feeding. Six-net-two light “six-net†refers to net, grass-net, net-water, material-net, shed-net, and cattle-body-net; “two-light†means that the grass and drinking water fed every time must allow the cow to eat and drink. Drug weight increase The so-called drugs, refers to endogenous hormones such as oestradiol, testosterone, progesterone and exogenous hormones such as trimethoprim to methyl testosterone; these are synthetic weighting agents. Under the method of subcutaneous implantation, implanted guns were implanted near the roots and 2 to 2.5 cm away from the rim of the helix. After being implanted, the beef cattle are rapidly increased in weight by the action of the above-mentioned drugs. However, planting should be stopped 90 days before slaughter. In winter and summer shade, it is necessary to ensure that the cow house is warm and that cows enjoy the sun. In summer, sun exposure should be prevented to prevent heat stroke, and the venue should be shaded, ventilated and light-transmitting. Disinfection and disease prevention Weekly lime water is used to spray cowsheds and cattle troughs each time to prevent cattle from developing diseases. In addition to regular disinfection, some drugs or foods that help digestion and prevent food production are usually fed to enhance cattle immunity. The benefits of adding urea to feed cows with urea are well known, especially beef cattle. The amount of urea added to cattle is generally 1% of the dry matter or 2% of the mix. Regularly brush the brush each time in the morning and afternoon to promote blood circulation and appetite. Restricted exercise uses beef ropes of about 1 meter to fasten beef cattle, limiting their movement, reducing physical exertion, and accelerating muscle storage. At the same time, beef cattle must be exempted from labor to shorten fattening time and improve meat quality. Deworming, wintering nematodes, worms, schistosomiasis, cysticercus parasites and other parasites seriously harm the growth of beef cattle, and can be directly fed with high-efficiency and low-toxic albendazole to remove insects. After removing the insects, the effect of increasing the weight of beef cattle is obvious.
Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.
