B36—lancaster Farming, Saturday, October 24,1981 Hog producers must ‘fine-tune 9 operations NEWARK, Del. Recently the cost ot producing hogs has been below the prices received. Such situations seem to be a part ot the hog cycle. The prolonged period ot depressed prices made this recent "down” phase a difficult one tor those with long-term commitments to hog production. "The present state ot our economy may mean the protits tor hog producers won't approach those experienced in the 19705,” predicts University ot Delaware Extension livestock specialist Richard Fowler. "The situation is a challenge to those who want to operate profitably in the years ahead. It calls tor some fine tuning of production systems.” Least cost performance is one way of improving teed efficiency. This program doesn’t produce the best gains ot maximize feed ef ficiency, but it does produce the cheapest gains. Little research has been done on this type ot feeding program for hogs, though it is a standard practice in broiler production. "Obviously, swine producers can’t afford to own a finishing pig for a year when tacilities and equipment are part ot the overhead costs,” says Fowler. "On the other hand, too much emphasis may now be given to the number ot days to market or feed efficiency when we measure nutritional adequacy of a diet.” Nutrients such as protein and energy must have greater digestibility, he says. The per centage ot protein lost in the feces ot a pig ranges up to one-tourth ot CORK GROWERS... DON’T MISS IT!!

Research being done at Texas A & M on protein digestibility particularly ammo acids shows that which is digested in the large intestine is useless to the pig. The nitrogen from protein absorbed in the fund gut or large intestine is excreted in the urine. Five grains and eleven high protein teedstutts are bmg tested to find out how much prutem is digested in the small intestine, where it is of value to the pig. The three most limiting ammo acids for pigs lysine, tryptophan, and threonine are the lowest m digestibility at the end ot the small intestine. The source ot protein also affects ammo acid digestibility. Lysine from soybean meal was found to be HEY GRAIN FARMERS.,. IF YOU NEED ANY OF THE FOLLOWING. CALL US!

More research is needed, but there may be an opportunity here tor. using lower quality protein teedstutts in practical swine diets, says Fowler. So watch tor turther developments in this area ot nutrition. Protein taken in by the pig must be more etticiently. Kesearch being done in England shows that a pig consuming approximately one pound ot protein daily deposits about one-tourth ot it in body tissue. Ot the protein which is lost, one-third is due to a poor balance ot ammo acids. This is a ditticull problem to overcome and probably involves the use ot something other than natural teedstutts.

Lysine and corn are already substituted tor soybean meal when costs justify it.

"This doesn’t mean we should be feeding elephants," says the specialist, but body weight, muscle, tat and metabolic rate increase trom conception to mat urity. This process can be shown by a curved line that gradually battens as the animal matures. The pig is most efficient at utilizing energy when it weighs about one-fourth ot its mature size. So, it a hug is mature at 60 pounds, energy ef ficiency is greatest at 1M) pounds. CSI grain SYSTEMS INC.
