Effects of extracted wheat germ oil in sheep and cattle.
one group was orally drenched with ethylene dichloride extracted wheat germ oil (edc-wgo) over two breeding seasons. In ewes drenched with edc-wgo the lambing percentages of mated ewes increased by 12\m=.\9%and the number of ewes lambing by 7\m=.\6%In Guernsey cows given edc-wgo there was no significant effect on the number of services per conception. The possible effects of oxygen uptake increasing components in edc-wgo on early reproductive processes are discussed.
Effects of Wheat Germ Oil on Reproductive Efficiency in Repeat-Breeder Cows
Summary Clinically normal repeat-breeder cows that had failed to maintain pregnancy after three or more services were alternately assigned to the experimental or control group. The experimental cows received 2oz of wheat germ oil on their feed once a week for six consecutive weeks. A significantly higher percentage of the 79 treated cows maintained pregnancy after the first post-treatment service than of the 88 untreated cows. The difference in post-treatment conception between treated and untreated cows that had three unsuccessful services before treatment was not significant; however, there was a highly significant difference in favor of the treated cows that had been bred four or more times before initiation of treatment.
Investigations on the rôle of organic matter in plant nutrition
1. As the result of decomposition of green manure in a swamp soil, the coarse fractions (including coarse and fine sand) of the surface layer (first 3 inches) decreased by 11·2 per cent. while the fine ones (silt+clay) increased by 9·8 per cent. in the course of 43 days. The effect was less pronounced in the manured soil maintained at 60 per cent. saturation, while no alteration was to be noticed in the case of the unmanured specimens. 2. Treatment with dilute hydrochloric acid prior to dispersion had no appreciable effect on the estimates of mechanical composition obtained in the different cases. Loss in solution was also comparatively small. 3. The silica-sesquioxide ratio increased slightly as the result of decomposition of green manure in swamp soil. The composition of the fine fractions was also altered, the total percentages of the oxides of iron, aluminium and silicon increasing from 90·5 to 99·3 in the course of 71 days. 4. The practical significance of the above and related observations has been discussed.
