“…light intensity, blood fraction, fasting and storage time) on blood components in broilers. Du et al (2023), who examined serum blood metabolites after fasting for 16 h in broilers at 49 d of age on restricted feeding found lower values than our findings for total cholesterol (67.14 vs. 135 mg dL -1 ), triglycerides (7.92 vs. 38 mg dL -1 ), and glucose (151 vs. 227 mg dL -1 ) and ALT (2.06 vs. 7.25 IU L -1 ) compared to the 12-h fasting in our study. However, the values for AST were higher (587 vs. 326 IU L -1 ), whereas the GGT values were close (24.78 vs. 29.59 IU L -1 ) to those of the present study.…”

We determined the impacts of light intensity, blood fraction, fasting and storage time on glucose, cholesterol, triglycerides, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyl transferase (GGT) concentrations in 140 broiler chickens assigned to two light intensities (5 or 20 lux/m²) and seven fasting times (0, 2, 4, 6, 8, 10, and 12 h). The collected blood was fractionated into serum or plasma and stored at -20°C for 0, 15, 30, 60, and 120 days. Serum glucose concentrations declined linearly by 1.15 mg dL-1 every 2 h of fasting, whereas plasma glucose responded quadratically (minimum point at 8 h and 13 min of fasting). Serum ALT concentrations showed a quadratic effect, with a maximum point at 3 h and 46 min of fasting. Serum GGT concentrations were not influenced by fasting time, whereas plasma decreased by 1.60 IU L-1 at each 2 h of fasting. The AST concentrations were influenced by fasting. Storage times influenced the glucose concentrations in a quadratic manner, with maximum points in serum and plasma at 95 and 72 days, respectively. Serum cholesterol and triglyceride concentrations increased linearly with storage time. Storage time caused a quadratic response on serum ALT, with a maximum point at 32 days, whereas there was a minimum point at 93 days in plasma. Concentrations of GGT increased linearly with storage. Glucose, triglycerides, AST, and ALT concentrations were highest at 20 lux. Samples for AST analysis can be stored up to 120 days at -20°C. Serum glucose, cholesterol, triglyceride, ALT, and GGT analysis is indicated with a 6 h fasting time, without freezing. The light intensity should be specified.

“…Dietary restriction (DR) is a robust nutritional manipulation that mimics resource limitations. It affects organisms' life‐history traits by influencing physiological and molecular pathways (Cornejo et al., 2007; Du et al., 2023; Kitaysky et al., 2001; Regan et al., 2020). One physiological marker of nutritional availability affecting life history is the insulin‐like growth factor 1 (IGF‐1).…”

Nutritional limitation is a common phenomenon in nature that leads to trade‐offs among processes competing for limited resources. These trade‐offs are mediated by changes in physiological traits such as growth factors and circulating lipids. However, studies addressing the sex‐specific effect of nutritional deficiency on these physiological variables are limited in birds. We used dietary restriction to mimic the depletion of resources to various degrees and investigated sex‐specific effects on circulating levels of insulin‐like growth factor 1 (IGF‐1) and triglycerides in Japanese quails (Coturnix japonica) subjected to ad libitum, 20%, 30% or 40% restriction of their daily requirement, for 2 weeks. We also explored the association of both physiological variables with body mass and egg production. While dietary restriction showed no effects on circulating IGF‐1, this hormone exhibited a marked sexual difference, with females having 64.7% higher IGF‐1 levels than males. Dietary restriction significantly reduced plasma triglyceride levels in both sexes. Females showed more than six‐fold higher triglyceride levels than males. Triglyceride levels were positively associated with body mass in females while showed not association in males. Overall, our findings revealed sex‐specific expression of physiological variables under dietary restriction conditions, which coincide with body size.
