Description

{Livestock fresh feed forage spraying hydroponics}

The present invention relates to a spraying apparatus for livestock fresh matter, and more particularly, to a seedling of barley, wheat, and the like loaded on a tray in a cultivating room by supplying appropriate temperature, light and moisture, So that it can be efficiently cultivated.

Fodder, which is related to the present invention, is also referred to as bio-fermented feed, or raw or second-seeded root, and is produced by cultivating barley seeds or wheat seeds through hydroponics without using soil or other soil substitute, 15 ~ 20cm) is said to have grown.

According to the analysis of the feed value of fresh forage, which is related to the forage, the crude protein content increased as the seeding period of barley seeds increased after harvesting the seeds of barley seeds, and 1kg of seed (DM 90% ), It was reported that 8Kg of forage (including root) of 10% of building content was produced. Protein content of general ingredient increased 1.5 times and crude fiber content increased 1.9 times. The total amino acid content was also 1.26 It is known that the number increases.

Forage crops such as bluegrass sprouts are rich in nutrients and minerals, and digestion and absorption rates are high, which leads to superior feed cost savings compared to grain feed. Antioxidants (composed of vitamins A, B, C, selenium and zinc) By neutralizing the body of the disease by self-healing and improve the immune system to prevent the abuse of antibiotics and livestock, such as livestock can survive well be able to live healthy cattle can be planned.

Vitamin A, which is contained in large amounts in the forage, improves the pregnancy conception rate of livestock and shortens the pregnancy cycle.

The effect of livestock on the feeding of livestock was investigated. In case of livestock and cattle, improvement of daily weight gain, improvement of meat quality and occurrence rate were effective. In case of dairy cows, , And it is known that horse has a remarkable effect such as reduction of common horse disease such as gastric ulcer and phlebophilus, improvement of horse race performance and shortening of recovery time.

In addition, in the case of pigs, the perfect formation of the fat layer results in the production of high quality pork belts and fast weight gain. In the case of laying hens, the increase in the size of the pigs, the thick yolk and the long laying period are effective. In the case of broilers and ducks, And so on.

On the other hand, when grain seeds such as barley and wheat are cultivated using soil or other soil substitute soil, it takes a great deal of time and effort to grow the seeds enough to feed the livestock, resulting in low productivity.
