Black farmers are still Black farmers, yet now are considered a part of minority or small or limited resource farmers/ranchers (SLRF/R) by the Department of Agriculture. Except for a few Southern states, their numbers have fallen from a remnant to a fragment in recent years. They continue to leave agriculture at a faster rate than whites. What few programs the Department has for this category of producers (SLRF/R) show genuine promise, provided they are pursued diligently by the Congress and the Department. Also vigorous enforcement of civil rights laws and directives of the Secretary and the new initiatives by the Office of Civil Rights Enforcement (OCRE) have to be sustained.  相似文献

Blood concentrations of thiamin, biotin, nicotinates, pantothenates, folates, riboflavin, vitamins A, B6, B12, C, E, beta-carotene and choline were analyzed in healthy animals (23 horses, 25 dogs, and 29 cats). B-Complex vitamins and choline also were analyzed in the liver of the dogs and cats. Vitamin concentrations in the blood and livers of dogs were similar; however, blood vitamin A and beta-carotene concentrations were lower in the cat than in the dog. Horses had a higher B12 blood concentration than did the dogs and cats. These data can be useful for detecting overt and hidden vitamin deficits in these species due to various conditions.  相似文献
