Fat Meter Helps Feed Formula

Fat Meter Helps Feed Formula

In many areas in the south, more than 90% of the farmers who handle sweet potatoes and cassava residues are using our technology. Only a small number of traditional farmers use cooked methods. However, they are also decreasing. Methods. For example, farmers in the surrounding areas of Nanning, especially in Guangxi Wuming County, the largest cassava starch production base in the world, most farmers are using this technology to treat cassava slag feeding pigs and other animals, and fermenting cassava residue in pig feeds. The proportion of pigs reached the highest 80% of pig sows, generally 30% piglets, pigs 40%, 50% pigs. The cost of breeding has been greatly reduced, and the incidence of pigs has dropped by more than 80%. Some farms have not used additional therapeutic drugs for more than one year since they were fed with fermented sweet potatoes (except normal vaccination). (The sweet potato starch content is higher than that of cassava.) It is recommended that the amount of fermented sweet potato be used at an average of about 50%. This is to balance the nutritional needs of the pig. Finishing pigs can generally reduce the cost of raising a pig by about 150-200 yuan, but the slaughter period is about 10 days longer than the full feed. One of the important indicators in the feed is the fat content. At this point, we can use the crude fat analyzer to determine the feed. The crude fat analyzer determines the fat content according to the Soxhlet extraction principle and the weight determination method. That is, the fat is dissolved in an organic solvent, the fat is separated from the solvent by extraction, then dried, weighed, and the fat content is calculated. There are various models such as SZF-06A Crude Fat Analyzer, SZF-06B Crude Fat Analyzer, etc.
