The inclusion of toxic adsorbent compounds can reduce the negative effects caused by the presence of Aflatoxin B1 and Ochratoxin A. Saffron petal extract can be used to potentially modulate the contaminated diets with Aflatoxin B1 and Ochratoxin A, best achieved with 750 mg/kg of saffron petal extract along with 0.1% yeast cell wall and 1% processed ...

Development of the Bursa of Fabricius in the Partridge and Pheasant
Development and regression of the bursa of Fabricius was measured in chukar partridge (Alectoris chukar) and ring-necked pheasant (Phasianus colchicus) from hatch to 40 and 34 weeks of age, respectively. Testes weights were recorded for 8 to 34-week-old pheasants and 12 to 30-week-old chukars.
