Prevention of vitamin B11 deficiency in poultry

Prevention of vitamin B11 deficiency in poultry

Folic acid, also known as vitamin B11 or leaf essence, plays a crucial role in the formation of new cells and the maturation of red and white blood cells. It is especially abundant in yeast powder, liver powder, and various plant-based feeds such as Cistanche, cottonseed meal, wheat bran, and green forages. While folic acid is present in many feed sources, it is relatively low in corn. In most commercial feed formulations, the levels of folic acid are generally sufficient to meet the needs of chickens. However, it's often recommended to supplement with a quality multivitamin, as not all products contain this essential nutrient. A deficiency in folic acid can lead to several health issues in young birds. Affected chicks may experience stunted growth, anemia, and neurological symptoms such as head and neck paralysis, where the bird stretches its head forward. They might also scratch the ground excessively and fail to develop proper feathering, resulting in pale or white feathers. Additionally, folic acid deficiency increases the need for choline in chicks. Even when 2 grams of choline per kilogram of feed is provided, it may still be insufficient, potentially leading to skeletal abnormalities like osteodystrophy. In adult birds, a lack of folic acid can negatively impact egg production and hatchability. To prevent or address folic acid deficiency, it's advisable to increase the amount of green feed in the diet. Feeding yeast powder, liver powder, or fresh liver can also help replenish folic acid levels effectively. If necessary, folic acid supplements can be added directly to the feed at a rate of 50 mg per kilogram. This approach ensures that the birds receive adequate amounts of this vital nutrient, supporting their overall health and productivity.

In the Arbas region of 105° east longitude and 40° north latitude where the temperature fluctuation between day and night can reach 50 degrees in winter, there is an essential native goat breed, the purebred Arbas Baby Cashmere Goat, which features thin and soft hair, a pair of horns and pink ears. Arbas Baby Cashmere Goat looks small yet are the nobles of goats.
The famous Arbas Baby Cashmere Goat, as a rare breed living in the Ordos Plateau of Inner Mongolia, is concentrated in Otog Banner, Otog Front Banner and Hanggin Banner in the western part of the Plateau. Sumu, Arbas, Otog Banner is the primary production area of Arbas Baby Cashmere Goat for its favorable natural environment, with Arbas Mountain in the west, vast natural pasture in the center and desert steppe in the south. The semi-arid steppe climate provides excellent conditions for animal husbandry.
Due to its location in the desert steppe, the area is dry and windy with little rainfall and much sand. The temperature difference between day and night is extremely high, and the annual average temperature is 6.4 °C. In the long, cold and dry winter, the lowest temperature reaches -30°C to -40°C late at night, while in the short, hot and arid summer, the highest temperature is 36.4°C and the lowest -32°C, with annual precipitation between 200mm to 400mm. The adorable, lovely and lively Arbas Baby Cashmere Goat grows in such extremely harsh conditions, thus can produce rare and quality cashmere.
Arbas Baby Cashmere Goat`s two coats are pure white. The top layer or outer coat is bright and coarse guard hair to protect the undercoat that is softer and finer down. The quality of the cashmere fleece is determined by three indicators: the diameter, length, and density of cashmere fibers. Due to its unique genes, Arbas Baby Cashmere Goat has a superiority that can never be duplicated. Its secondary hair follicle is smaller than those of other goats, and its cashmere has an average diameter between 13μm to 15 μm. It can even produce cashmere with a perfect diameter of 14.5μm, with a pure cashmere content of over 55%, which is unique worldwide. The preciousness of cashmere results from the small amount of production of each goat. Therefore, Inner Mongolian Arbas Baby Cashmere Goat was officially named by the People`s Government of Autonomous Region in 1988 and was listed on the National Register for the Conservation of Animal Genetic Resources as Class-1 protected breed by the Ministry of Agriculture in 2001.
