To study the effect of intravenous lipid emulsions enriched with gamma-linolenic acid on plasma fatty acids and series-2 prostaglandins to determine if the slow conversion of linoleic acid by delta-6-desaturase to gamma-linolenic acid could be bypass

INTRODUCTION PREVIOUS studies have established that buquinolate 1 at concentrations of 0.00825% and 0.011% in feeds effectively controls mild to severe Eimeria tenella infections in the chicken. Although Eckman et al. (1968) showed that micronization

The immune state of buquinolate-medicated chickens infected with Eimeria acervulina was examined subsequent to drug withdrawal. Chickens fed a ration containing buquinolate 1 0.011% together with chickens fed an unmedicated ration were immunized by o

The cecal mucosa of chickens immunized by multiple doses of Eimeria tenella oocysts was susceptible to invasion by sporozoites when the birds were challenged 14 and 21 days after the last im- munizing dose. Fewer parasites were observed in immune tha

Acquired immunity to reinfection with Eimeria tenella was reexamined. The study suggests that chickens, immunized by multiple doses of E. tenella, develop only a condition of "relative immunity." Immunity, as assessed by clinical signs of the disease
