80-acre
1.In Denver, an 80-acre park opened in September on the site of another disused airport.
4.The agricultural and economical character of this variety shows: growing luxuriantly without lodging, stronger resistibility and earlier maturation. The oil yield per acre is 20-50% more than the variety presently cultivated on production scale (80-1).
6.newly hatched chicks of Arbor Acre which consisted of half male and half femals were fed from 1 to 28 day of age on diets containing different concentrations of vitamin E(40, 80mg/kg)and ascorbic acid(200, 400, 800mg/kg).
8.Two hundred forty four week old Arbor Acre broilers were used to study the effect of dietary vitamin C supplementation on production performance and the capacity of biosynthesis of vitamin C in broilers under heat stress (room temperature 32～35℃,humidity 80%～82%)and thermoneutral status(room temperature 20～25℃,humidity 65%～70%).
