(4) From forty-two to seventy days old, the following mixture: Corn meal, two parts by measure; wheat bran, one part; beef scraps, 10 per cent of this bulk; coarse sand or grit, 5 per cent; green food, 10 per cent. Mix with water to a dry crumbly state and feed four times a day. The hours for feeding are 6 a. m., 10 a. m., 2 p. m., and 6 p. m. Below is given another system of feeding ducks for marketing at ten weeks of age. This system is practically the same as the one given above, differing only in the ingredients used for the first two parts or until the duckling is twenty days old. The method given below is used successfully by one of the largest duck raisers on Long Island. It is divided into three parts, as follows: (1) From time of hatching to seven days old, feed equal parts by measure, corn meal, wheat bran, and No. 2 grade flour, and 10 per cent of this bulk coarse sand. Mix with water to a dry crumbly state and feed four times a day. (2) From seven to fifty-six days old, feed equal parts by measure, corn meal, wheat bran, and No. 2 grade flour; 10 per cent of this bulk beef scraps; 10 per cent coarse sand, and 12½ per cent green foods (green rye, oats, clover, etc.). Mix with water to a dry crumbly state and feed four times a day. (3) From fifty-six to seventy days old, feed two parts by measure. Corn meal; one part wheat bran; one part No. 2 grade flour; 12½ per cent of this bulk beef scraps; 10 per cent coarse sand; 12½ percent green food. Mix with water to a dry crumbly state and feed three times a day--morning, noon, and night. Give last feed an hour before sundown. When ducks are raised for breeders they are fed differently from those intended for market. They are not forced so much as are the latter, and less fattening food is given them. The corn meal and beef scraps are reduced to one-half the quantity used in the above rations. The following is an excellent ration: Equal parts corn meal, wheat bran, green food, 5 per cent beef scraps, and 5 per cent coarse sand or grit. A ration for breeding (laying) ducks is recommended as follows: Fifty per cent, by measure, corn meal; 15 per cent wheat bran; 15 per cent green foods (cooked vegetables, such as potatoes, turnips, etc.); 12 per cent beef scraps, and 8 per cent coarse sand or grit. Mix with water to a dry crumbly state and feed twice a day, morning and night. After the breeding season is over and the ducks have stopped laying they are changed from this to the equal-parts ration, as given above for ducklings from seven to fifty-six days old. MIXING FEED.
