The Effect of Trace Minerals on Growth Performance and Vitamin B12 Synthesis of Steers

Ammonium lactate — feedstuff and feedstock

“…Also in 1954, researchers at Ohio State University found that ammonium acetate and ammonium propionate were less toxic and had higher retention values than urea when fed to fistulated lambs. Both ammonium salts were found equal to urea, but not equal to soy protein, as measured by growth rate and feed efficiency (Bentley et al, 1954). A method for manufacturing a high nitrogen, low lactose product from whey was described by Amott, Patton & Kesler (1958 The conclusion drawn is that the ammonium salts of volatile fatty acids could be used as feed ingredients provided that they can be manufactured economically.…”

Effects of over‐load iron on nutrient digestibility, haemato‐biochemistry, rumen fermentation and bacterial communities in sheep

“…It has been reported that a stimulation of cellulose digestion by iron has been shown in vitro with rumen bacteria and in feeding trials with steers (Bentley, Moinuddin, Hershberger, Klosterman, & Moxon, 1954;Hungate, 1966, pp. It has been reported that a stimulation of cellulose digestion by iron has been shown in vitro with rumen bacteria and in feeding trials with steers (Bentley, Moinuddin, Hershberger, Klosterman, & Moxon, 1954;Hungate, 1966, pp.…”

“…In the present study, there was a quadratic response to over-load iron in the diet such that the digestibility of DM, OM, NDF and ADF was increased for 500 mg Fe/kg supplemented group. It has been reported that a stimulation of cellulose digestion by iron has been shown in vitro with rumen bacteria and in feeding trials with steers (Bentley, Moinuddin, Hershberger, Klosterman, & Moxon, 1954;Hungate, 1966, pp. 349-353).…”

Influence of nutrient additions, physical form of the ration, and interval of feeding on performance of lambs

“…A number of workers have been able to improve the performance of cattle receiving rations containing low quality roughages by supple mentation with trace minerals. Bentley et al (1954) improved the per formance of cattle receiving a ration containing timothy hay by adding alfalfa ash or trace minerals. Cobalt was considered to be the first limiting trace element in this study.…”

“…Adding brewer's yeast, fish meal or vitamin B^ to the ration resulted in slight improvement in the per formance of the cattle. Bentley et al (1954) conducted experiments with steer calves individually fed a ration of timothy hay, ground ear corn, urea, cellulose, calcium, phosphorus, iodized salt and vitamin A. The addition of a trace mineral mixture or alfalfa ash significantly increased feed consump tion and daily gain of these steers.…”
