Healing, roasting, and pel leting have been claimed to kill molds. If mold is present and the temperature is high enough, the molds will be destroyed. But many of the mycotoxins are R. S. Adams Dairy and Animal Science Extension There is appreciable evidence that feeding hydrated sodium and calcium alumino silicate such as Novasil may partially reduce the adverse effects of aflatoxin in the diet and levels of aflatoxin found in the milk of animals fed conta minated feed. Depending upon the level of mycotoxin in the total diet diy matter, the aluminosilcate may not reduce aflatoxin in milk to legal maximum levels for human use. Apparently alumi nosilicates absorb the aflatoxin and increase its excretion via the digestive tract. Sodium or calcium bentonite also has been shown to reduce effects of afla toxin on health and performance. Unfortunately, there is of yet little research evidence which indicates that aluminosilicates or bentonite are effective in reducing effects of other myco loxins upon animal perfor mance or health.

For example, vomito xin levels in your com might be 50 ppm. If you reduce that com from 1,00 to 200 pounds per ton, you would still have 4 ppm Feed Additives you should not depend on these additives to alleviate problems with other mycotoxins, espe cially those produced by Fusar iums, which are apparently more prevalent under North eastern conditions and more likely involved than aflatoxin in performance and health problems. Effective levels of alumino silicates and bentonite range from .5 percent to 1.0 percent of the total ration dry matter. The lower level of .5 percent has been of value with aflatoxicosis in swine, while 1.0 percent has reduced aflatoxin in milk by 25 percent to 44 percent in- some research. Since no harmful effects have been noted at these intakes, these fairly inexpen sive ingredients could be included even in diets with appreciable mycotoxins other than aflatoxin present. Howev er, their use should not negate the probable need to reduce levels of contaminated feed in the diet, or at least temporarily discontinue feeding items with appreciable mycotoxin or mold content to alleviate problems or 717-866-7565 in the feed - high enough fr" I**** Farmln B’ Saturday, February 13.

For some producers, it may be tempting to buy “screenings” from feed and flour mills since the price is attractive. But if the grain was cleaned after a hot and dry, or excessively wet growing sea son, the screenings probably ascertain whether they are involved with them. When effective, changes in ration level of mycotoxins and/or use of feed additives may result in marked improvement within as little as three to seven days. 24 Hr.

If at all possible, avoid feeding the contaminated grain to sows. Aborted litters are expensive, Hot and dry weather, and cool, wet weather can lead to mold growth in grains. *+***+*++**++*+++*++**+**** Chemgro * * * * * * * * * * * It 1992 CORN SHELLING PLOTS ♦ And Well Guarantee It 4 MIKE BUCKWALTER LEON MUSSER ji,Maytown, PA Harvested Nov. 9. 1992 Mmheim.

SUMMARY If test weights and protein levels from grains grown under these conditions arc normal, then the grain may be OK. If a chemical test shows the grains are negative for mycotoxins, then it’s even a safer bet that the grain is usable. But you can never be sure until you feed it. If you see any of the following symptoms in your pigs, be suspicious of mycotoxin poisoning. • Feed refusal • Swollen vulvas • Prolapsed rectums or vaginas • Convulsions • Death • General reduction in performance. # 1 IS DAVID FREY )f Lancaster, PA Harvested Nov. 9, 1992 jL Variety Bu/Acre 15.5% T CHEMGRO 7191 187.0 J CHEMGRO 7692 176.9 *■ CHEMGRO 7392 176.6 CHEMGRO X 316 CHEMGRO 6988 CHEMGRO 7793 CHEMGRO 7888 177.7 176.9 174.6 174.1 164.6 Hardy 6334 Gutwein 2751 CHEMGRO 7386 LEROY E.
