Proceedings
A highly cellulolytic fungus, Penicillium funiculosum was grown for four days at room temperature on pulverised sorghum stalks and bagasse and subsequently sun-dried after the initial acid hydrolysis of the substrates in autoclave at 1.5 lb pressure for 30 minutes, followed by neutralization with alkali. Addition of 10 percent molasses and 2 percent salt to the bioenriched feeds gave optimum palatability. Seven 4 years-old bucks with similar body weights were divided into three groups and were offered either the biotreated sorghum-stalk feed, bagasse or the conventional 'Sugras' concentrate feed in such a way that each animal received equal quantity of nitrogen. Proximate analysis of the untreated and the same biotreated substrates revealed that the initial protein content of 3 percent increased to 13.20 percent and 11.30 percent in sorghum-stalks feed and bagasse, respectively. Semen evaluation after a 60 days feeding period revealed, that sperm concentration per ml, sperm motility and live sperm percentaje significantly increased in bucks receiving biotreated feeds, as compared to untreated controls. This was attributed to additional availability of amino acids to the breeding bucks
