In addition to corn, sorghum, bean cake and other carbohydrates, protein feed and high-quality forage, it is best to make some supplements with high sugar content and rich in vitamins for feeding. The fattening effect will be better. . 1. Germinated feed. Principle and production method: After the germination of the grain feed, the beef cattle can be supplemented with vitamins. The germinated feed of 1 cm in length is rich in vitamin E, and the germinated feed of about 7 cm contains more carotene and vitamin B2 and vitamin C.
The preparation method is as follows: the seed is immersed in warm water of 18 to 20 ° C for 15 hours, and then spread in a wooden plate or a fine sieve, the thickness is about 5 cm, covered with a sack or a straw mat, and the clean water is often sprayed to keep it moist. The indoor temperature is maintained at about 25 ° C, and it can be germinated after about 7 days. Germinated feed is not only a good supplement for beef cattle, but also an ideal supplement for bulls. Each cow can feed 100-120 grams per day to meet the needs.
Especially in the winter and spring seasons where the green feed is lacking, it is better to feed the cows with the right amount of germinated feed. 2. Glycation feed. (1) Principle: Using amylopectin in the cereal seed, a part of the starch is converted into maltose to improve palatability.
(2) Production method. In the ground seeds, the volume is 2 to 5 times of hot water, and the mixture is evenly mixed. It is placed at 50-55 ° C. After 6 hours, the sugar content of the feed can be increased to about 10%.
The addition of 2 kg of malt per 100 kg of seed has the best saccharification. The saccharified feed is added to the beef cattle diet in a proportion of 10%, and the cattle like to eat and the fattening effect is remarkable.
Optical filters are devices that selectively transmit light of different wavelengths
Filters are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging. These filters are typically used in the life science, industrial, or R&D industries
CCRQ can provide precision filters for many applications, including bandpass interference filter, Cut off filters, UV bandpass filter, Narrow Bandpass Filter, ND filter, Long Pass Filter, Short Pass Filter,Negative Filter or Notch filters, dichroic, color substrate,HR Filter, AR filter, Splitter.
