| Rhizomys sumatrensis is the largest species of Rhizomyidae in China.With the growth of the breeding industry in recent years and the short of product processing chain,the problem of bred rhizomys sumatrensis being in oversupply is gradually emerged.Influenced by the Covid-19 epidemic in 2019,rhizomyidae breeding industry for edible purposes has been banned.Therefore,it is very urgent for people to objectively understand the edible value of rhizomyidae and promote the subsequent processing of products,thus effectively transforming the industry.This implies the exploration of subsequent processing production is demanded.Currently,most of large-scale rhizomys sumatrensis breeding farms choose to clear the feces by incineration,which is not just a waste but also pollute the environment.In order to deeply understand the nutritional value of rhizomys sumatrensis,explore the rationality of having high market price from the nutritional perspective,and to study the feasibility of feces composting among the breeding processes,we conduct this research.In this dissertation,the meat quality and nutritional properties of 10 samples are examined,including rhizomys sumatrensis,rhizomys sinensis gray,chicken,pig and cattle,then the nutritional value of rhizomys sumatrensis muscle and daily consumption animal muscle are comprehensively contrasted and studied;the nutrients facts,organic carbon,heavy metals,trace elements and tetracycline-antibiotic of 10 samples of feces of rhizomys sumatrensis,rhizomys sinensis gray,chicken,pig,cattle and sheep are assessed,followed by the aggregate analyses of the feasibility of fertilizing rhizomys sumatrensis’s feces.The results reveal the following:1.There is no obvious difference in muscle quality and nutritional properties between rhizomys sumatrensis and rhizomys sinensis gray.Protein content and amino acid for nutrition quality in the muscle of rhizomys sumatrensis is inferior to chicken,pig and cattle.The proportion of protein is 20.01%,which is significantly lower than that of rhizomys sumatrensis,chicken,pig and cattle(P<0.05).The amino acid index of rhizomys sumatrensis is 78.71,which is higher than that of rhizomys sumatrensis and chicken,but is lower than that of cattle and pig.Its nutritional value of fatty acid is high,and the proportion of unsaturated fatty acid is relatively large.The trace elements are high in terms of copper,iron and selenium.The contents of vitamin B2 and vitamin E are particularly rich.According to the current market price and nutritional value of rhizomys sumatrensis,the cost performance is not quite effective.It is therefore suggested that the processing industry of rhizomys sumatrensis should diversify production development so that a sound development of breeding industry can be maintained.2.The total nutrient in the feces of Rhizomys sumatrensis is 5.84%,which is not significantly different from that of Rhizomys sinensis Gray,but significantly lower than that of other experimental animals(P<0.05).The contents of heavy metal elements arsenic,mercury,lead,cadmium and chromium are 0.016mg/kg,0.005mg/kg,12.5mg/kg,0.340mg/kg,13.3mg/kg.Therefore,it is suitable for fertilizer treatment. |
