“…Moreover, knowledge about this enzyme in birds has not changed much in the past 14 yr (see reviews in Duke 1986 andDenbow 2000). Accordingly, alkaline phosphatase activity falls in the intestine during starvation and is partially restored by refeeding in cockerels (Majumdar and Panda 1989), though this pattern was never reported in birds' plasma before this study.…”

ABSTRACTAn investigation of the effects of fasting, subfeeding, and refeeding on plasma biochemistry was carried out on 22 captive yellow-legged gulls Larus cachinnans Pallas. These birds showed the same fasting endurance model described in other species, but with an important decrease in glucose plasma concentration and very great differences between individuals when reaching the deterioration limit, suggesting a moderate physiological adaptation to long periods of fasting. A different model was proposed in subfed gulls in relation to fasted gulls, based on lipid and protein use, which could be reflected by changes in nitrogen wastes and triglyceride levels in this experiment. Thus, the subfed gulls might use protein directly from the diet as an energy source, thereby reducing the use of fat stores. The gulls quickly recovered body mass during the refeeding period, but while some plasma substances quickly reached their initial values, others showed many changes before the end of the experiment, which could reflect a process of metabolic restabilization. These results contribute to a better knowledge of fasting, subfeeding, and refeeding processes in birds and can be added to a recent study about fasting in gulls.

“…La PA est localisée dans la bordure en brosse des microvillosités de la muqueuse intestinale et le poids sec de cette muqueuse, ainsi que sa teneur en PA, sont abaissés de J3 à J7 lors de diverses infections coccidiennes (Allen, 1987). Chez le poulet, la mise à jeun provoque à elle seule une chute de la PA dans la muqueuse intestinale (Allen, 1987;Majumdar & Panda, 1989). La chute de la PA plasmatique est cependant supérieure chez les sujets infectés à celle des sujets pair-fed (Yvoré et al, 1972).…”

“…Observations of the intestinal AP indicates that its activity is also directly related to the presence and the amount of food in the alimentary tract. It has been demonstrated that AP activity is closely related to the day-night fluctuation of food intake (Martinková et al 2000) and decreased after fasting in neonatal (Baker et al1987) and adult animals (Majumdar and Panda 1989). On the other hand, food restriction had an opposite effect i.e.…”

The effect of microgravity on functional development of the small intestine of Japanese quails incubated for 2-3 d and hatched on the orbital station MIR was examined. After 5 d of space flight duodenal and jejunal alkaline phosphatase (AP) activity of the experimental group was compared with the AP activity in quails of the same age hatched on the Earth (laboratory controls). Shortterm microgravity leading to decreased food intake resulted in significant increase of AP activity in both duodenal and jejunal enterocytes (P < 0.001) of the experimental quails. The results suggest that increased AP activity probably reflects the delayed functional development of the small intestine as a consequence of inapropriate food intake during non-physiological conditions of space flight.
