Complete collection of sheep farming technique video tutorials, with detailed explanations of scientific breeding methods
Sheep farming techniques mainly include feeding and management techniques, disease prevention and control techniques, breeding and reproduction techniques, lamb feeding and management techniques, forage processing techniques and pen construction, etc.
Sheep shed construction
The sheep shed should be located on high, dry ground, facing the sun and sheltered from the wind. Leave 10—20 sq m of feeding area in front of the shed, and install fixed feed troughs and drinking water utensils. There should be drainage ditches outside the shed, and bamboo mats or cement flooring should be laid inside. In winter, in cold areas, plastic film should be used to cover the shed, which can raise the shed temperature by 4—7°C and benefit sheep growth. Different types of disinfectants should be used in rotation, such as 20% lime milk, 10% bleaching powder solution, etc., to regularly disinfect the sheep shed, exercise yard, feed troughs, drinking vessels, feeding tools and pens.
Separate shed management
Shed-fed sheep should follow a factory-style production model, with sheep of different ages, different breeds and different body conditions raised in separate sheds. Specialized birthing rooms and lamb sheds, meat sheep sheds, ewe sheds, ram sheds, and isolation sheds for sick sheep should be set up, along with corresponding feeding and management measures.
Breed sheep selection
Select excellent breeds suited to local conditions with large body size, fast growth, high reproduction rate, strong adaptability, good meat quality and high benefits. For the paternal line, the South African Boer goat is the first choice, followed by China's Matou goat; for the maternal line, Saanen dairy goats, Hebei white goats, etc. can be chosen.
Mating management
Regularly replace breeding rams from other places, put ear tags on breeding rams and ewes and keep mating records, recording in detail the numbers of the breeding sheep, mating time, mating method and lambing situation, and control natural mating of rams and ewes in a planned way to avoid breed degeneration caused by inbreeding.
Scale farming
The scale of sheep farming should be appropriate and can be determined according to conditions such as the amount of existing family farmland, the quantity of forage and feed, labor and the amount of funds invested. Generally, raising about 20 breeding ewes is suitable, and the annual income can reach ten thousand yuan. Since a single household may not be able to put up so much money at once, do not be greedy for scale when first starting to farm; keep exploring and summarizing farming experience and develop in a snowballing way.
Density management
Sheep are ruminants and need a relatively long time each day to eat forage and ruminate. Therefore, the sheep pen should have enough trough space and activity space, and each sheep should have 1.5—2.5 sq m of activity area.
Feed matching
Sheep are livestock that mainly eat roughage, with concentrate as a supplement. For large-scale feeding, it is best to "grow grass to raise sheep," so that fresh green grass can be eaten all year round. Sheep farmers should open up dedicated land for green feed and artificially plant forage grasses such as alfalfa and ryegrass. In addition to feeding green grass in summer and autumn, after the green grass is harvested in autumn it can also be sun-dried into hay or made into silage to feed sheep. Corn can also be planted for silage to supply sheep for year-round feeding. When preparing concentrate, in addition to a certain amount of corn, protein feeds such as soybean meal, bran, fish meal and bone meal should also be matched in proportion. In addition, if appropriate amounts of compound feed additives such as rumen metabolism regulators and urea slow-release agents are added, the benefits will be better. In addition, large-scale sheep farming must have clean drinking water for the sheep.
Disease prevention and immunization
Group-raised goats are prone to disease, mainly including lamb dysentery, streptococcosis, contagious ecthyma, nematodes, sheep lice, etc. The policy of "prevention is more important than treatment" should be carried out, and vaccination and integrated prevention and control work for key diseases should also be done well.
Daily management
Large-scale sheep farming should be based on self-breeding and self-raising, with reasonable grouping. If grazing, rotational grazing by divided areas should be carried out. Also pay attention to management work such as brushing and hoof trimming.
Castration and fattening
For lambs used for fattening, it is best to castrate them within 7—21 days after birth. Castration at this time helps improve meat quality, makes them docile, facilitates management and enables rapid fattening.
