Resumo

Hawthorn extract has been used for ameliorating cardiac disorders and pulmonary hypertension. Flavonoids and oligomeric proanthocyanidins are considered to be responsible for the positive health effects of hawthorn extract. The effect of Hawthorn extract in the water supply on feed intake, growth, carcass traits, internal organ weight, cardiac indices, the concentration of serum proteins and the incidence of pulmonary hypertension syndrome was evaluated in broiler chickens. At one day-of-age, 225 chickens were assigned to one of three experimental groups where 0, 0.1 and 0.2 ML of hawthorn extract was added per one liter of drinking water. Feed intake, live weight gain and carcass weight increased when hawthorn extract was included in the drinking water at a level of 0.1 and 0.2 ML/L (p 0.05). Compared to no extract, the addition of Hawthorn extract in the drinking water (p 0.05) reduced the proportion of the body attributed to abdominal fat, liver and heart (p 0.05), and decreased the percentage of birds that died or showed clinical symptoms of pulmonary hypertension syndrome (p 0.05). Serum protein concentration was (p 0.05) higher in chickens that received the hawthorn extract in the drinking water compared to no addition of extract in the drinking water. Hawthorn extract has shown potential for use as a herbal medicine to aid in the prevention of physiological cardiac disorders and pulmonary hypertension in chickens.(AU)
