Most species will generate colostrum just prior to giving birth. Colostrum contains antibodies to protect the newborn against disease. In general, protein concentration in colostrum is substantially higher than in milk. Fat concentration is substantially higher in colostrum than in milk in some species, e.g. sheep and horses, but lower in colostrum than in milk in some other species, e.g. camels and humans. In swine, fat concentration of
Milk car milk cans had been soldered from three pieces, but they were later replaced by rolled and molded single-piece cans, which avoided uncleaned cracks in the solder joints.
