Recently, one reader of Matang Township, Rudong County, reported that the newspaper “Cowage 110†reported that there are more than 100 goats in the family. The existing corn bran, soybean hulls, broad bean hulls, corn and soybean pods are intended to be prepared from these raw materials. Feed feed rams. How to match?
Answer: Corn husk is a byproduct of deep processing of corn and can be directly used as feed. However, because of its high fiber content, poor palatability, and low nutritional value, it is difficult to be directly digested and absorbed by animals. Studies have shown that after the fermentation process of corn husks, the protein content of the corn husks has been improved, the fiber content has been reduced, the nutritional level has been significantly improved, and a large number of beneficial bacteria and various enzymes have been contained, which promote the digestion and absorption of livestock and poultry and improve The distribution of intestinal microflora enhances immunity and promotes growth. It is best to use it after fermentation. The amount added should not exceed 15%.
Soybean skin mainly refers to the outer layer of soybean coating material. Soybean hull has high nutritional value, containing 13.9% crude protein, 0.63% calcium and 0.17% phosphorus. Because the main component is cell wall or plant fiber, it cannot be well digested and absorbed by monogastric animals such as pigs and chickens. But can be used by ruminants. In the production process, it can replace the use of corn and wheat bran.
Broad bean skin, also known as broad bean shell, is the seed coat of broad bean. Its crude protein and crude fiber content are high. Generally, it is rarely used as a supplement for feed protein or calcium preparations. It is a good plant cellulose and has the effect of diuresis and diarrhea.
The available energy of corn is high, crude fiber is very small, only 2%, and nitrogen-free extracts are as high as 72%, and the digestibility is up to 90%. The fat content is 3.5% to 4.5%, which is a good utilization rate of livestock and poultry. An energy feed. Soybean meal is a by-product of soybean oil extraction. According to different extraction methods, it can be divided into a dip bean dip and a dip soya bean dip. The production process of a dip soy bean meal is advanced, and the protein content is high. It is used in production at present. Can use up to 30% to 50% of crude protein.
The rearing management of the rams is divided into two stages: breeding period and non-breeding period. The feed formulation must be adjusted accordingly. When corn and soybean meal are used as the main energy feed and protein feed, the feed formulation can be used: corn 53%, bran 7% of the skin, 20% of soybean meal, 10% of cottonseed cake, 8% of fish meal, 1% of salt, and 1% of stone powder. The amount of mixed condiment fed by each ram for non-combination period is 0.5 to 0.6 kg per day and it is fed in two batches. During the breeding period, the amount of the mixed concentrate was 0.8-1.0 kg, which was fed 4 times. At the same time, daily supplementation of roughage 1.6 to 1.8 kg (grass powder 1.4 kg).
In addition, calcium and phosphorus ratios in ram diets should not be less than 2-1. Because of the high content of phosphorus in grains, if calcium is not paid attention to, the imbalance of calcium and phosphorus can easily lead to urinary stone disease. When ram stock is self-matched, it is best to use a ram premix.
Extraction Kit Magnetics Bead Method
This standard specifies the terms and definitions, classification, technical requirements, test methods, identification, labels and instructions for use, packaging, transportation and storage of nucleic acid extraction kits (magnetic beads method) (hereinafter referred to as "kits"). This standard It is suitable for extracting and purifying human genomic nucleic acid and its fragments from various clinical samples such as serum, plasma, whole blood, cerebrospinal fluid, milk, saliva, urine, sputum, swab, tissue or paraffin-embedded tissue by magnetic bead method , Pathogen nucleic acid kit. Pathogen nucleic acid includes deoxyribonucleic acid (DNA), ribonucleic acid (RNA), etc. This standard does not apply to nucleic acid extraction reagents contained in closed systems that cannot extract nucleic acid extraction products for detection.
This kit uses magnetic beads with unique separation function and a unique buffer system to separate and purify high-quality virus from serum, plasma, lymph, cell-free body fluid, cell culture supernatant, urine or various virus preservation solutions DNA/RNA. The uniquely embedded magnetic beads have a strong affinity for nucleic acids under certain conditions, and when the conditions change, the magnetic beads release the adsorbed nucleic acids, which can achieve the purpose of rapid separation and purification of nucleic acids. The whole process is safe and convenient, and the extracted viral DNA/RNA has high yield, high purity, stable and reliable quality, and is especially suitable for automated extraction of high-throughput workstations. The nucleic acid purified by this kit can be applied to various routine operations, including RT-PCR, fluorescence quantitative PCR and other downstream experiments.
