Pine needle powder is collected from the young shoots and needles that have been trimmed, and dried and crushed. Pine needles are pink green and fragrant, and they are a kind of livestock and poultry feed additives with higher nutritional value being developed in recent years.
If China reasonably and effectively uses these pine needle powder raw material resources, it can not only save a large amount of cereal feed grains and vitamins and other additives, but also improve the quality of livestock products, reduce feed costs, and increase the economic benefits of feed and breeding.
Feeding value of pine needle powder
l, rich in carotene content
The content of carotene in various pine needles is generally between 69-356 mg/kg. Carotene can be converted into vitamin A in the body of the livestock, which can effectively prevent and treat skin diseases caused by vitamin A deficiency in various livestock and poultry.
2, contains a variety of vitamins
Pine needle powder contains a lot of vitamin C and vitamin E and so on. The content of vitamin C is about 950-2203 mg/kg. Long-term feeding can promote the growth of livestock and poultry, increase their anti-stress and immunity, and prevent some common livestock and poultry diseases. The content of vitamin E is generally between 201-1266 mg/kg. Regular use of pine needle powder has the function of preventing and inhibiting the peroxidation of the cell membrane of organisms, and can play an anti-aging effect.
3, contains a lot of protein
The content of protein in Pinus taiwanensis is 11.9%, the content in larch is 15.2%, and the content of other varieties is about 8%. Pine needle powder not only has a high protein content, but also has a comprehensive amino acid composition in proteins. It contains a total of 17 kinds of amino acids, including 8 kinds of amino acids necessary for animals.
4, rich in trace elements
Pine needle powder contains more than 40 trace elements, which are richer than those contained in barnyardgrass. The contents of trace elements in pine needle powder were (mg/kg); copper 56, manganese 215, iron 329, zinc 38, selenium 3.6, cobalt 0.58, molybdenum 0.87.
The content of lipids in pine needle powder is also high. According to a rough estimate, the content of crude fat in pine needle powder is between 3.8 and 13.1%. The fatty acids contained in the crude fat have unsaturation and can effectively improve the quality of meat.
In addition, pine needle powder also contains plant bactericides and plant hormones, which can inhibit the growth and reproduction of harmful microorganisms in the organism and promote the growth of livestock and poultry.
Pine needle powder test results
Adding 3% pine needle powder to the feed can improve the overall immune function of the chicks, increase disease resistance, resilience and survival rate, and promote the growth of chicks. Xi'an Academy of Agricultural Sciences added 6% pine needle powder to layered chicken hens. The egg production rate increased by 9.1%, the fertilization rate was 94.1%, and feed was saved by 15.1%. According to another report, adding 2-5% pine needle powder to male rabbits for feeding has a significant effect on raising male rabbits' libido and mating, and can also promote estrus and ovulation in female rabbits. Experiments have shown that adding 3-5% pine needle powder to pig diets increases the weight gain rate by more than 15% and saves 0.11 kg of fine material per 1 kg of weight gain. For piglets fed with pine needle powder at an early stage in two months At weaning, the increase in weight can be increased by 17.64%, with significant economic benefits.
After repeated tests and repeated arguments, the use of pine needle powder in animal feed is generally 3-5% for pigs and cattle, 3.5-5.5% for chickens and ducks, and 4% for aquatic products.
Pine needle powder processing methods and precautions
The newly collected pine needles are placed in a cool, ventilated place and defoliated and chopped to prepare for drying. When drying, the temperature should be controlled at 80-90°C, and the moisture should be sampled regularly. When the water content of the raw material drops to 8-10%, it can be crushed. The crushed pine needle powder can be bagged. Packaging must use black plastic bags, stored in a dark, ventilated, dry, clean room, the storage period is generally not more than two months. Otherwise, the vitamins contained in pine needle powder are easily lost. Pine needle powder processing process is: raw materials (pine branch) collection → transport into the plant → unloading → stacking → defoliation, chopping → drying → smashing → finished product packaging. The main equipment includes defoliation machines, choppers, dryers, crushers, and gas supplies.
