The aim of this study was to investigate the effects of dietary garlic on the growth performance, intestinal mucosa morphology, and pulmonary hypertensive response in broiler chickens with pulmonary hypertension induced by 3, 5, 3′-l triiodothyronine. Chicks were reared for 42 days and treated with triiodothyronine (1.5 mg/kg diet) and 0 (control), 0.2, 0.6 or 1% garlic powder. Intestinal segme...
The ability of young rabbits to digest a solid diet was evaluated according to the weaning age: 21 (W21, 12 litters) or 35 (W35, 12 litters) days of age. From 14 days onwards, the rabbits were fed the same pelleted feed. Three methods were compared to estimate the faecal digestibility in the young rabbits, between 24 to 28 and 38 to 42 days. Digestive balance at ileal and faecal levels was dete...
