Ecological breeding method for black pigs under forest

Abstract

The invention discloses an ecological breeding method for black pigs under a forest, and belongs to the technical field of livestock breeding. The method comprises the following steps that (1) leewardand apricus forestland with good ventilation, sufficient water sources and convenient drainage is selected, wherein the shade density of the forestland is 50% or above; (2) wild boars serving as female parents and black pigs serving as male parents are utilized for hybridization, excellent hybrid first-generation sows are selected to be hybridized with Duroc, and produced offspring are placed inthe forestland in the first step for breeding; (3) 60-85-day-old pigs are selected, and rotational grazing stocking is started; (4) daily management of the pigs under the forest is conducted; (5) diseases are prevented and treated. By means of the method, the forestland resources are relied on, the ecology and space under the forest are fully utilized, and the black pigs suitable for growing underthe forest are reasonably bred; the method has the main advantages of being ecological, healthy, environmentally friendly and free of pollution, is a good breeding mode combining agriculture and forestry, and has broad development prospects and good economic and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to an ecological breeding method for undergrowth black pigs. Background technique [0002] The black pig belongs to the genus Suidae of the Mammalia Artiodactyla order Suidae. It has oily black hair, compact body, quick response, strong disease resistance and fecundity, and cold resistance. It is native to Zhaodong. In the "Compendium of Materia Medica" written by Li Shizhen in the 16th century, there is a special "Animal Department Porkaceae", which records the different medicinal values ​​of various parts of black pigs, which is very precious. The "full protein" contained in black pork can help repair human tissues. Regular consumption of black pork can provide balanced nutrients, so that modern people can still obtain minerals, vitamins and protein during dieting.

AI Technical Summary

Problems solved by technology

[0003] Most of the existing methods of raising pigs under the forest do not consider the size of the environmental carrying capacity and the ecological threshold, and the excessive activity of pigs is extremely serious to the destruction of vegetation. What's more, there is no grass in the forest, and the ground is uneven, which reduces the number of understory plants. The soil layer is exposed, the soil is compacted, and the long-term heavy rain weather causes water and soil erosion, destroying the ecological environment of the forest land

Moreover, no land trimming is carried out after raising pigs, which seriously affects the soil's nutrient cycle function

In addition, the pig manure from raising pigs under the forest causes various environmental hazards. The pig manure under the forest flows into the water body with the rainwater, causing serious eutrophication of the water body, corrupting the water quality, and killing aquatic organisms.
