“…Protein and starch content in CSM/corn flour extrudate is higher, while fat is lower than commercial extrudates. Our results are consistent with other studies where a higher protein content was shown when using composite flours and/or agro-industrial residues for extrusion than when only corn is used [33][34][35]. Mixing CSM and corn flour can significantly (p < 0.05) increase dietary protein and lower fat content in snacks as shown in this work and other findings, whereas composite flours can improve the nutritional value of food [36][37][38][39].…”

The results of the present study indicate that glandless cottonseed meal (CSM) can be incorporated in extruded corn flour snacks at a 10% content level, which increases snack protein content to 12.8% and reduce fat content to 6.2%. To improve snacks’ nutritional quality, CSM and corn flour were extruded using a simple screw extruder. An expansion index (EI) ranging of 1.2 - 4.7 was obtained. Penetration force (PF) was 7 - 9 times harder than other extruded products. High extrusion temperature and high CSM concentrations decreased (p < 0.05) EI, water activity, and water absorption index. Higher CSM concentrations can be incorporated into extrudates if snacks are processed at higher extrusion moistures. CSM increased (p < 0.05) extrudates’ PF giving them a unique crunchy texture. CSM decreased (p< 0.05) extrudates’ water solubility index. Extrusion conditions used showed a 68.5% starch gelatinization, and a starch availability of more than 97%, which explains the high expansion index obtained

“…The second group of lizards ( n = 12) was fed captive‐bred, corn‐raised crickets (experimental diet) throughout the same period as the lizards on the control diet. The corn‐raised crickets were fed only corn, a poor‐quality diet that lacks essential amino acids (Benton, Harper & Elvehjem 1955; Contreras, Elías & Bressani 1980; Webb, Hedges & Simpson 1998), for at least 1 month prior to being eaten by the lizards. We chose corn as a cricket diet because this C4 plant has higher relative abundance of 13 C compared to the C3 plants forming the diet of the control group (Bender 1968) (see Table 1 for isotope values for the diet treatments).…”

Lizards combine stored energy and recently acquired nutrients flexibly to fuel reproduction

Summary 1.Energy allocation strategies for reproduction are viewed typically as a continuum between reliance on 'income' (recently acquired energy) vs. 'capital' (stored reserves) for fuelling reproduction. Because ectothermy facilitates long-term energy storage and often involves low feeding rates, traditional views suggest that many ectotherms rely heavily on stored reserves for egg production. 2. We explored the temporal relationship between energy intake and expenditure in a multi-clutching lizard ( Amphibolurus muricatus ) by evaluating the effect of maternal nutrition on reproductive output and by contrasting δ 13 C measurements of the maternal diet and endogenous energy stores with that of the eggs produced. 3. Our experiment revealed that females utilize both endogenous energy stores and recently acquired food to fuel reproduction; this pattern did not shift seasonally from first to second clutches produced. Importantly, however, egg lipid was derived primarily from capital, whereas egg protein was derived about equally from both income and capital. 4. Overall, these results suggest that the energy allocation strategy used for reproduction differs among egg components, and that the use of recently acquired energy for reproduction may be more widespread in ectotherms than thought previously.
