| Abstract | Hydrogen cyanide in cassava, which is a cyanogenic plant, was reported to be transformed into the non-toxicthiocyanate (SCN-) in cows and is partly eliminated via the milk. Milk SCNisused in the antimicrobial function of thelactoperoxidase system (LPS) in milk while lactoperoxidase activity was reported to be useful as a possible indicator of somaticcell counts (SCC). We investigated the effects on the hygienic quality of raw milk and milk SCC through supplementation offresh cassava peel (FCP) in the diets of dairy cattle. Twenty-four Holstein-Friesian crossbred, lactating dairy cows were blockedby lactation first and then stratified random balanced based on days in milk, milk yield, and body weight into three groups of 8cows each. The treatment groups were: 1) cows fed a control diet of 6.49 kgDM/d of 21% crude protein concentrate together withad libitum corn silage; and 2) and 3) cows were fed the same control diet supplemented with top-dressed 500 and 1000 g/d ofFCP, respectively. Dietary treatments had no effect on nutrient intake, weight change, milk yield or composition. The raw milkexhibited increased SCNconcentrationand decreased SCC. FCP supplementation greatly increased the efficiency of theantibacterial activity of the LPS. The results demonstrated that increasing milk SCN- maintained the hygienic quality of the rawmilk by supplementing the diets of dairy cattle with FCP. Since there was also a commensurate reduction in the SCC, it may bepossible to use FCP supplementation as an alternative measure to prevent mastitis in lactating dairy cows. |
