Kffect of Thiamin Chloride on Eimeria nieschulzi Infection of the Rat.

It was shown in previous experiments1, 2 that wheat middlings and wheat bran supplements had the property of creating in the rat host a condition more favorable for the development of the coccidium Eimeria nieschulzi than the control ration, or even the control ration supplemented with white wheat flour. In a thorough recheck of the effects of wheat middlings (gray shorts), the following test ration (parts by weight) was used: beet sugar, 71; soy bean oil meal, expeller process, 10; casein, commercial, medium fineness, 10; normal salt mixture (Harris), 4; lard, 3; cod liver oil, 2. When 30 parts of wheat middlings were substituted for some of the sugar, casein, and soy bean oil meal, increased coccidium development, as indicated by counts of oocysts passed by rats on the 2 rations, continued to be evident. Since, as was previously concluded, it seemed that amount of fiber could be ruled out as the causative factor, an investigation of the effects of extracts of wheat middlings was indicated.Weighed amount...

Dried Skim Milk and Other Supplements in the Ration During Gaecal Coccidiosis of Chicks

SummaryFurther evidence is supplied for the unfavorable effect of dry buttermilk in the ordinary type of growing ration when White Leghorn chicks become infected with sizable doses of Eimeria tenella. It is now shown that dry skim milk has an effect similar to that of dry buttermilk. It made little difference when soy bean oil meal (expeller process) was substituted for a considerable part of the meat element in meat scraps, or when a fine grade of low-temperature sardine meal was substituted for dry milks.Further, it was brought out in chicks on 2 different rations that there was no difference in mortality from infective inoculations of 100,000 and 200,000 oocysts (Experiment 3).

Soy Bean Oilmeal and Ground Soy Beans as Protein Supplements in Dairy Rations

I t has been a problem to develop on Indiana farms crops which would supply sufficient protein in the dairy ration. Up to this time cottonseed meal, linseed oilmeM and gluten meal have been the chief ~igh protein concentrates that have been used in the dairy ration. As all of these feeds must be purchased and brought to the farm, a much smaller quantity of them has been fed than that which should be fed. Recently there has been considerable interest in the growing of soy beans on Indiana farms, and inquiries have been very frequently made by Indiana dairymen as to whether soy beans could be used as protein supplements in the dairy ration. A number of early feeding trials have been made comparing soy bean oilmeal and soy bean cake with cottonseed meal as a protein supplement in the dairy ration, and they were found equal to or superior to cottonseed meal for production. Similar results have been obtained with ground soy beans (1) (2) (3). At the Indiana station (4), it has been found that ground soy beans together with a mineral mixture might be supplemented with good results for purchased protein concentrates in the ration of hogs. Feeding trials conducted recently (5) indicate that ground soy beans can be supplemented for linseed oilmeal in the dairy ration, and that soy bean oilmeal has practically the same feeding vaiue as linseed oilmeal for milk production. I t has been suggested by some feed manufacturers interested in soy bean products, that farmers might send their soy beans to the mills where the oil would be extracted and the oilmeal returned to the farmers, the miller accepting the oil for his part of the transaction. In the feeding of ground soy .beans, the preparation of this feed
