“…Decrease in triacylglycerols and fatty acids from treatment P301L81 suggests hepatic lipolysis and release of fatty acids to plasma. Liver lipogenic activity in rainbow trout O. mykiss has been reported, and such activity is sensitive to fatty acids that reach the liver through blood (Hickiling & March 1982). In this concern, the lipogenesis is thereby reduced when dietary lipid concentration is high.…”

“…This sparing effect of sugar was facilitated by higher dietary lipid contents. When the plasma glucose concentrations exceed the ability of liver for both lipogenesis and glycogen synthesis, there is a remarkable elevation in muscle glycogen synthesis (Hickiling & March 1982). In this particular, as dietary lipid was in excess, the relative delivery of glucose was high.…”

Growth and metabolism were investigated in juvenile tambaqui (Colossoma macropomum) fed with isoenergetic diets in four treatments with protein (P) lipid (L) in g kg−1: P350L49; P301L81; P253L113 and P205L145, respectively. The experiments were carried out in the laboratory facilities. Fish growth, the intermediary metabolites (total sugar, lactate, pyruvate, ammonia, protein, fatty acids, triacylglycerols, amino acids and glycogen), and the enzyme activities of lactate dehydrogenase, malate dehydrogenase, glutamate dehydrogenase, aspartate aminotransferase and alanine aminotransferase were assayed. Fish from treatments P350L49 and P301L81 depicted the best growth. Increase in glycolytic, glycogenolytic and lipolytic activities in liver was observed following dietary lipid increase. In fish fed with high lipid levels, the energetic demand was supplied by enhancement of muscular glycogenesis and lipolysis. The plasma metabolic profile reflected the blood function on metabolites delivery to tissues underlining biochemical adaptations because of changes in the feeding. In conclusion, the increase in dietary lipid plus protein decrease resulted in (i) reduction in fish growth, (ii) augment of liver glycolysis and glycogenolysis (iii) increase in muscular glycogenesis and (iv) predominance of lipolytic metabolism.

“…Further in this regard, Hickling and March (1982) reported that in broiler-type chicks feed withdrawal had little effect on muscle glycogen, whereas White Leghorns showed a general decline. The statistical analysis of the glucose values (Table 4) showed a significant breed difference in the effects of protein and oil concentrations in the conditioning diets on plasma glucose response to refeeding.…”

Broiler-type and White Leghorn chicks were given diets containing 30.5, 26.2, or 22.3% protein with and without addition of 5% corn oil during an 8- to 9-week conditioning period. The absolute weight of the abdominal fat pad was greater in the broiler-type birds on all dietary treatments. As a percentage of body weight the abdominal fat pads were similar in broiler-type and White Leghorn birds only when the diet contained 30.5% of protein without added oil. Following a 16-hr fast, plasma glucose was higher in the broiler-type than in the White Leghorn birds, whereas plasma triglyceride concentrations were higher in White Leghorns. In birds refed a high-fat meal, plasma glucose showed little change except in the broiler chickens previously fed the 30.5% protein diet without added oil. In these birds plasma glucose declined over a 5-hr period to reach a mean value of 130 mg/100 ml. Plasma triglyceride concentrations in both breeds were markedly elevated within 45 min of refeeding with a high-fat meal, but the peak concentrations were higher in the White Leghorns than in the broiler-type birds. Previous consumption of the high-oil diet increased postprandial triglyceride concentration in the plasma of the broiler-type but reduced it in the White Leghorn chickens. The difference in response of the chickens of the different genetic stocks is attributed to differences in the development of the activities of the systems associated with 1) fatty acid absorption and movement of triglycerides from the intestinal mucosa to the circulation and 2) clearance of plasma triglycerides to the adipocytes as a result of lipoprotein lipase activity.
