Cud no roughage but high levels of highly digestible starchy concentrate. Some dairy cows in intensive systems of milk production may have sub-acute acidosis because of the high rates of cereals in their diets relative to an insufficient amount of forage. However most producers provide adequate fodder in the form of hay to prevent this. Cud Cud is a portion of food that returns from a ruminant's stomach to the mouth to be chewed for the second time. More accurately, it is a bolus of semi-degraded food regurgitated from the reticulorumen of a ruminant. Cud is produced during the physical digestive
Chewing gum specific in its inhibition of "Streptococcus mutans", bacteria that are significant contributors to tooth decay. Xylitol inhibits "Streptococcus mutans" in the presence of other sugars, with the exception of fructose. Xylitol is a safe sweetener that benefits teeth and saliva production because, unlike most sugars, it is not fermented to acid. Daily doses of xylitol below 3.44 grams are ineffective and doses above 10.32 grams show no additional benefit. Other active ingredients in chewing gum include fluoride, which strengthens tooth enamel, and p-chlorbenzyl-4-methylbenzylpiperazine, which prevents travel sickness. Chewing gum also increases saliva production. Food and sucrose have a demineralizing effect
