“…Previous investigations have indicated that fasting decreases the lipogenesis capacity and increases the lipolysis rate of chickens (Calabotta et al, 1985;Goldman et al, 1985;Hasegawa et al, 1994b;Leveille et al, 1975). Other works noted increased activities of lipoprotein lipase (Hasegawa et al, 1994a) and hormone-sensitive lipase (Anthony et al, 1990) in fasting chickens. Also, the lipid metabolism of chickens in the laying period differs from that in the growing period (Walzem, 1996).…”
