We compared heat production (HP) and plasma lipid metabolites between meat‐ and egg‐types of Nagoya breed chickens during embryonic development. To investigate HP and respiratory quotient, oxygen consumption and carbon dioxide production were measured using an open‐circuit calorimeter system. HP was significantly lower in meat‐ than in egg‐type chickens during embryonic development, and HP gradually decreased with developmental stage in both types. The respiratory quotient was constant at approximately 0.68 at every embryonic stage investigated, and the value was similar in both types. Plasma concentrations of triacylglycerol, nonesterified fatty acid, glycerol and D‐3‐hydroxybutyrate, which are associated with lipid metabolism, were similar in both types during embryonic development. These results demonstrate that chicken embryos selected for rapid growth of Nagoya breed have characteristic lower HP, and that when selecting chickens for rapid growth, HP is an important parameter during embryonic stages. 相似文献

To compare the hepatic function of broiler and layer chickens (Gallus gallus domesticus) at various embryonic stages and hatching, the total lipid and triacylglycerol (TG) content were determined. The chicken embryos accumulated a large amount of lipids in the liver and the total lipid content gradually increased toward hatching, though no significant difference was observed between broilers and layers. The TG contents in the liver increased considerably with developmental stage. At embryonic day 14 the TG content in the liver was similar between broilers and layers; thereafter, it was 1.3 and 2.2 times higher in broilers than in layers at embryonic day 18 and for newly hatched chicks, respectively. Chick embryos accumulate an excessive amount of cholesterol ester in the liver, but cholesterol ester is replaced by TG after hatching. The results of hepatic TG contents in the present study suggest that the development of the hepatic function between broilers and layers may already differ at embryonic stages. 相似文献
