Energy balance of pregnant diabetic rats.
Pregnancy and diabetes lead to metabolic alterations in the energy balance that may not be completely independent. The objective of the present study was to look at the alterations induced by type 1 diabetes mellitus on the energy balance of pregnant rats and the offspring. Diabetes was induced by streptozotocin injection 15 d before the starting of pregnancy. The rats had their energy balance ...

15 صفحه اولDietary lysine and threonine requirements of the pregnant sow estimated by nitrogen balance.
Two experiments were conducted to determine the lysine and threonine requirements of gestating sows. In the first experiment, four levels of lysine (0.34,0.42,0.48, and 0.56% crude lysine, and 0.24,0.31, 0.38, and 0.45% standardized ileal digestible lysine) were compared in eight multiparous Large White sows. Each sow received successively the four diets according to a Latin-square experimental...
متن کاملNitrogen requirement of pregnant gilts.
Eleven Yorkshire x Landrace gravid gilts were used in two Latin square trials to determine the N requirement for pregnancy. Semipurified diets were formulated to be adequate in indispensable amino acids (IAA) and other nutrients. Diets were fed once daily (1.82 kg); L-glutamic acid, corn sugar, powdered cellulose, and soybean oil percentages differed to maintain isocaloric diets. In Trial 1, si...
متن کاملNitrogen balance after injuries.
An increased excretion of nitrogen after injuries in experimental animals and in man was described by Cuthbertson (1930). In a series of papers he and his colleagues discussed and explored almost all the facets of this phenomenon which have since been studied (see, e.g., Cuthbertson, 1929, 1930, 1936, 1942; Cuthbertson & Tompsett, 1935 ; Cuthbertson, McGirr & Robertson, 1939). He investigated t...
