“…The study on obese ponies also showed that restricted feeding of obese ponies led to a reduced LDH (Van Weyenberg et al, 2008). ALP was closely associated with metabolism of the Ca and P (Jurani et al, 2004). In consistent with the results in restricted chicks (Rajman et al, 2006) and broiler breeder hens (Hocking et al, 1996(Hocking et al, , 2001, our study showed that 30% energy restriction significantly increased ALP level of broilers.…”

Fifty 18-day-old broilers were used to investigate the effects of 30% energy restriction from 18∼48 d on growth and slaughter performance, serum biochemical parameters, and gene expression of WDTC1 and Lpin2 in hepatic tissue. Fifty 18-day-old Arbor Acres female broilers were randomly divided to ad libitum group (control) and energy restriction group (experimental) and housed individually. The ad libitum group broilers were fed ad libitum with control diet, while energy restriction broilers were subjected to 30% metabolizable energy restriction (the supply of other nutrients was the same as that of ad libitum broilers). The results showed that: (1) Energy restriction significantly increased the feed efficiency (gain/feed) of birds. The average daily gain, the relative weight gain and the feed efficiency of energy restriction broilers were lower than that of ad libitum broilers during the earlier stage of the experiment (from 18∼39 d). While at latter stage of experiment (from 40∼48 d), the average daily gain, the relative weight gain and the feed efficiency of energy restriction broilers were higher than that of ad libitum broilers. (2) Energy restriction significantly reduced the abdominal fat ratio and the subcutaneous fat thickness, increased the muscle stomach weight, muscle stomach ratio, glandular stomach ratio, pancreas ratio, spleen ratio and the bursa of Fabricius ratio. There was no significant difference in leg muscle ratio and breast muscle ratio between control and experimental groups. (3) Energy restriction significantly increased serum superoxide dismutase, alkaline phosphatase, and serum uric acid, decreased serum total cholesterol, high-density lipids, malondialdehyde, lactate dehydrogenase and blood urea nitrogen. (4) Energy restriction significantly elevated Lpin2 expression level in hepatic tissue, whereas it did not significantly affect the expression of chicken WDTC1 gene in hepatic tissue.

“…However, glucose plasma levels have shown to be highly variable because glucose is used as a rapid and immediate energy source, and depends on metabolic rate, body size, and food intake (Umminger 1977;García-Rodríguez et al 1987b). In addition, the increase in glucose level with age observed for Osprey nestlings might be a consequence of increases in metabolic rate and weight, as already noted for several species (e.g., González and Hiraldo 1991;Ferrer and Dobado-Berrios 1998;Villegas et al 2002;Juráni et al 2004). In fact, as already explained for triglyceride and protein metabolism, higher glucose mobilization would be expected at the end of the nestling period, when physical activity is higher as nestlings prepare for their first flight.…”

We assessed the normal values for 15 blood plasma biochemistry parameters and three indices of body condition (IBCs) in free-living Osprey (Pandion haliaetus) nestlings in Brandenburg (Germany). Values were compared with those of other raptors, and possible sexual and age-related differences were examined. In addition, we looked for possible relationships of habitat quality (measured in terms of foraging conditions and human disturbances) to nestling nutritional condition and productivity. Female nestlings showed higher mean urea levels and lower glucose values than males, which could be related to higher growth rates and nutrient demand of females at the end of the nestling period. Seven parameters also showed variation with age, probably relating to increasing body mass, metabolic rates, and physical activity during the pre-fledging stage. Conversely, the IBCs showed poor correlations with selected nutritional parameters, probably due to the homogeneously acceptable nutritional conditions of the nestlings. Finally, we found that Ospreys did not seem to adjust initial parental investment in relation to habitat quality, since productivity was not affected by habitat indicators. However, in large broods, but not in small ones, nestling nutritional condition improved as foraging conditions improved. These results suggest that females that are in better physical condition seem to produce more and better nourished nestlings in better foraging conditions. Wir beurteilten Normalwerte für 15 biochemische Blutplasma-Parameter und drei Indizes für die Körperkondition (Indices of Body Condition-IBCs) bei freilebenden nestjungen Fischadlern (Pandion haliaetus) in Brandenburg (Deutschland). Die Werte wurden mit denen anderer Greifvogelarten verglichen und mögliche geschlechts-und altersabhängige Unterschiede wurden untersucht. Zusätz-lich haben wir denkbare Zusammenhänge zwischen der Habitatqualität-gemessen anhand der Lage von Gebieten der Nahrungssuche und anhand menschlicher Störung-und dem Ernährungszustand der Nestlinge sowie der Reproduktion untersucht. Weibliche Nestlinge zeigten höhere Harnstoff-Durchschnittswerte und geringere GlukoseWerte als männliche, was mit einer höheren Wachstumsrate und einem höheren Nährstoffbedarf bei den jungen Weibchen gegen Ende der Nestlingsperiode zusammenhängen kann. Sieben Parameter zeigten Veränderungen abhängig vom Alter, wahrscheinlich im Zusammenhang mit der zunehmenden Körpermasse, mit dem höheren Metabolismus und mit der steigenden körperlichen Aktivität während der

“…Biochemical evaluation of blood constituents in birds allow to monitor health, to detect subclinical disease (Bowes et al, 1989) and to analyze metabolic alterations due to various endogenous and exogenous factors as in humans (Ross et al, 1978;Bowes et al, 1989;Meluzzi et al, 1992;Krasnodebska-Depta and Koncicki, 2000;Harr, 2002;Jurani et al, 2004;Rajman et al, 2006). During the growth period, the blood lipid metabolites fluctuate in broilers strongly in association with energy metabolism.…”

Accumulation of body fat is the major problem associated with initiation of various diseases in fast growing broiler chickens. Methods to restrict the accumulation of body fat have met with limited success. The objective of this study was to evaluate the effect of Avocado Non-Saponifiable Fraction (NSF) in broiler chicken (from day 14 for 27 days) on body fat accumulation, growth performance, organ weight and plasma lipid profile. Supplementation of avocado NSF for 27 days has resulted in positive changes in plasma lipid profile with 50% decrease of abdominal fat and 33.8% increase in body weight compared with normal control chickens. The Avocado NSF improved body composition in broilers through higher lean-to-fat ratio and hence has a potential to improve overall health profile and reduce metabolic diseases in chickens.
