Every step, every suck, every breath can keep him alive or kill him. Which way it goes depends on his anti's. Antibodies from the sow's colostrum. Antibiotics fromyou. The first few squirts of colostrum are loaded with antibodies. Within hours, they've faded away. That's when you and Pfizer play wet nurse. Do this: Give every newborn pig a squirt in the mouth of Pficer Terramycin Animal Formula Soluble Powder right after birth. 3j*. Repeat the next two days. 61. It works so well it's like buying an extra weaner for a dime. Why Pfizer Terramycin? Because it fights more different kinds of germs, gets into the blood faster, and keeps working longer than most other pig antibiotics you can buy. How's that for upping the odds? Pfizer Science for the world's well-being* Agricultural Division Cbas. Pfizer & Co., Inc. New York, N. Y. 10017 \j lifton Willis and his son, Bob, are two of the happiest fellows you'll find anywhere around Belvidere, Illinois. They have good reason to be. In 1964, they shot for 200 bushels of com to see if it were possible to even come close to such a high mark. The highest plot yielded 199.1 bushels per measured acre. A second check on an adjoining plot yielded 195.7 bushels. These yields were at field moisture levels. But just having a high yielding corn plot wasnt the big cause of their jubilance. They had 160 acres of corn that averaged just under 150 bushels per acre . . . and this was in a year when moisture was short! Yet the thing that was really amazing about it all was the fact that until this year they had never had an average yield of over 95 bushels. ONE FARMER TERRAMYCIN 8 ANIMAL FORMULA SOLUBLE POWDER What caused the big jump in yields? "It was four things," said Clifton Willis. (1) Variety (2) plant population (3) adequate fertilizer and weed control and (4) efficient harvesting machinery. We planted the best hybrid corn to come the farmer's way since hybrids were developed . . . XL-45. We bought the best combine on the market ... a Gleaner." The reasons Willis gave for hieing XL-45 were not only its high yielding ability, but the fact that it is a short corn that can be planted thick, won't break over, and the ears hold on until picked. The plant population was considerably higher than most farmers plant. On most of their test plots they got a stand of 33,700 in 38-inch rows. However, they had some that was only 23,000. Curiously enough it was the 23,000 stand that yielded the top yield of 199.1 bushels. The entire 160 acres of corn, though, had a stand of 22,000. The Willis' figure that the best plant population must have been somewhere between 22,000 and 30,000. As for fertilizer, the Willis' 'didn't skimp. They knew they couldn't get the corn without it. All fields got 200 pounds of 6-24-24, plus 80 pounds of actual nitrogen. Extra potash was also plowed down on some fields. The high yielding plots got a little more nitrogen ... 120 pounds instead of 80 as a side-dressing, plus an additional 200 pounds of a special fertilizer containing trace elements. As for insecticides, the Willis' used Aldrin at planting in 14-inch bands at 1J» pounds per acre. They also treated the seed with *Heptachlor. To assure clean fields, they banded a pre- emergence herbicide for broadleaf weed and grass control. All fields were shallow cultivated twice (in the same day). The double cultivation was to knock out some stubborn grassy centers. Average expenses that went into the corn crop except for a figure for land rent (perhaps $25 to $30) and depreciation on the equipment, came to $37.50 per acre. This included an allowance of $2.50 per acre for gas. Figuring everything, (rent and depreciation, too) the Willis' cleared somewhere in the neighborhood of $90 per acre from their corn. The Willis' accredit a good share of this $90 per acre profit to their harvesting methods. They realize that field losses at harvest time are net losses. "We spent some time adjusting the machine and put a good driver on the seat and then our Gleaner did an almost perfect job," said Willis. This coming season will see the Willis' going every bit as strong, but with a few slight changes. They are going to try 30-inch rows with only chemical weed control. Plant population will be between 28 and 30,000. The Willis' are selling about half of their corn and feeding the remainder to a 40-cow dairy plus some heifers and beef cows. "Dairying is a good business," said Bob Willis, "but I'm hoping that I can get things worked out to put my time and effort into more corn in the future . . . maybe even go out of the dairy business."
