摘要: Summary During the years 1955–57 inclusive measurements of growth rates have been obtained from some 289 lambs. Approximately half these suckled on ewes implanted with l-thyroxine. Growth lambs used to indicate lactation level treated and control ewes. Evidence response has (1) mature thyroxine (a) six weeks before lambing, (b) two-three days after (2) two-tooth about time mating.
