Swollen and/or bleeding gums are the first oral symptoms of malnutrition. As the malnutrition continues, the teeth may begin to decay. When only the gums are affected, the oral effects of malnutrition can be reversed; however, once the teeth begin to decay, the damage is permanent.
The density of milk depends on fat content and its type. The density varies from 1.032kg/L (whole milk) to 1.035kg/L (skim milk). This can go as low as 1.026kg/L under cert â¦ ain conditions, but a low density could also indicate added water.
Holstein cows typically calve for the first time when they are 23 to 26 months of age, with healthy calves weighing an average of 80 to 100 pounds at birth. Holsteins have a gestation period of nine months. Holstein cows give more milk than any other dairy breed in the U.S. The average Holstein cow produces around 23,000 pounds of milk, or 2,674 gallons, of milk each lactation. With a standard lactation lasting 305 days, that comes out to 75 pounds, or almost 9 gallons of milk per cow per day.
