Changes in the size distribution of goat steroidogenic luteal cells during pregnancy
(Elsevier Science Bv, 2003)
Experiments were conducted to investigate the size distribution of goat steroidogenic luteal cells throughout pregnancy. Corpora lutea were collected from very early (<6 weeks), early (6-8 weeks), middle (9-14 weeks) or ...
The effects of supplemental niacin in laying hen diet on performance and egg quality characteristics
(Ecole Nationale Veterinaire Toulouse, 2003)
This study was carried out to determine the effects of dietary niacin (0, 250, 500, 1000 and 1500 mg/kg ration) on layer performance. A total of 120 commercial hens (28 weeks of age) were divided in five groups, each ...
Raman spectroscopy and imaging of β-carotene in live corpus luteum cells
(Elsevier Science Bv, 2002)
Raman spectroscopy has been used to identify and locate beta-carotene within individual living luteal cells. The cells were either freshly prepared or cultured; the latter was incubated in the presence or absence of ...
Effects of increases in vitamin C supplementation in the laying hen rations on serum concentrations of vitamin C and vitamin A
(Ecole Nationale Veterinaire Toulouse, 2002)
This study was carried out to determine the effects of layer rations containing 0, 50, 100 and 200 mg/kg vitamin C on vitamin C and vitamin A concentrations in serum of hens. A total of 96 commercial hens (28 weeks of age) ...
Size distribution of steroidogenic and non-steroidogenic ovine luteal cells throughout pregnancy
(British Soc Animal Science, 2002)
The present study examines the size distribution of ovine steroidogenic and non-steroidogenic luteal cells throughout pregnancy. Cells were isolated from corpora lutea collected from early (:! 8 weeks), mid (9 to 14 weeks) ...
