Efficient breeding method for free-range beef cattle
Choose a good variety
To cultivate beef cattle, we should choose the offspring of excellent meat bulls such as Charolais, Limuzan and Simental, which are crossed with local yellow cattle and cows, and choose calves or bred cows with short head and wide forehead, big mouth and thick neck, deep body, long front and rear body, short middle body, loose skin, large body without rich muscles, obvious edges and corners and wide back.
management of standardization
When the weather turns cold, it is necessary to prevent thieves from entering the house; Frequent ventilation to reduce humidity; When the weather is fine, get more sunshine. Reasonable preparation of diet, increase the supply of concentrate, improve the energy level, ensure the balance of various nutrients, enhance resistance, prohibit feeding frozen feed and drinking water regularly.
Scientific feeding
While grazing, it is necessary to scientifically and reasonably match the diet according to the local feed sources and their own conditions. Choose the right way to gain weight. Here are some fattening methods for your reference.
Fattening method of concentrate supplementary feeding
In areas with vast grassland and excellent grass quality, beef cattle can basically eat enough after grazing, and then supplement concentrate after grazing to meet their protein and energy needs. After deworming, cattle mainly graze and then concentrate on fattening. 3-4 kilograms of concentrate, 50-60 grams of mineral additives and 20-30 grams of artificial salt, fed twice a day.
Urea fattening method
The feeding amount of urea is 50-75g/ head/day. When mixed with the diet, the addition of urea is about 2.5% of the diet, and it is stirred evenly. At the same time, the feed in protein should be reduced by 1/4- 1/3 to supplement energy feed.
Fattening method of distiller's grains
In the early stage of fattening, distiller's grains 13 kg, corn stalk 4 kg and mixed concentrate 3.5kg；; In the middle stage of fattening, distiller's grains 17 kg, corn stalk 4 kg and mixed concentrate 4 kg; In the later stage of fattening, 20 kg of distiller's grains, 4 kg of corn stalks and 4.5 kg of mixed concentrate. Distiller's grains should be fresh and high quality, and those that are rotten, moldy, frozen and sandy should not be fed to avoid poisoning.
Fattening method of silage corn
In the early stage of fattening, 26 kg of silage corn, 6 kg of mixed hay, 0.3 kg of corn/kloc-,50 g of salt, 60 g of calcium hydrogen phosphate and 50 g of mineral additives; In the middle stage of fattening, 24 kilograms of silage corn, 6.5 kilograms of mixed hay, 2.2 kilograms of corn, 50 grams of salt, 60 grams of calcium hydrogen phosphate and 50 grams of mineral additives; In the later stage of fattening, 22kg of silage corn, 5kg of mixed hay, 3.5kg of corn, 50g of salt, 60g of calcium hydrogen phosphate and 50g of mineral additives. Pay attention to the quality of silage when fattening silage corn, so that cows can have an adaptation process, from less to more, and then feed them in large quantities after getting used to it.
Fattening method of ammoniated straw
Crop straws are crushed to 1-2 cm by a pulverizer, and the cows are allowed to eat freely after ammoniation. At the same time, a proper amount of concentrate should be supplemented, and the concentrate ratio is: corn 65%, bean cake 10%, bran 18%, bone meal 2%, shell meal 2%, mineral and vitamin additives 2%, and salt 1%.
