Abstract/ Executive Summary:

Eight different silages were prepared using rice straw as basal ingredient with poultry excreta and/or urea, Each silage consisted of similar quantities of molasses and dry matter. In vitro digestibility of these silages were determined after supplementing with leucaena leaves at 15% of the silage dry matter. The average values for dry matter digestibility of the silages supplemented with leucaena were compared with those of the ensiled straw without supplementation. It was found that the values of the earlier experiment were lower than those of the latter. Similar results were also observed with organic matter digestibility. The reason was thought to be the presence of toxic factor in leucaena leaves or the incompatibility of loucaena with silage,

Program Area: Animal Health and Management

Commodity: Straw

Objectives:

To study the effect of supplementation of leucaena to straw ensiled with poultry excreta and/or urea on it's in vitro digestibility.

Methodology:

Straw was chopped and spread on the concrete floor. Urea was dissolved in little water first and then with molasses since mixing of urea directly with molasses did not result in uniform mixing. The solution was then sprayed over the chopped straw and filled in the polyethylene bags. The grinded poultry excreta (PE) was mixed with water molasses and sprinkled over the chopped straw and filled in bags. After sealing tightly the bags were kept in the dark room for fermentation. All the above silages were fermented for a period of 12 days and the representative samples from each silage were dried and ground for proximate analysis and also for in vitro digestibility. Leuceens teucocephete tree leaflets with pinnates were collected from the bipinnate compound leaves rejecting their rachis. These were then kept for proximate analysis and also for in vitro digestibility along with different silages. The first trial was conducted for determining dry matter (DM) and organic matter (OM) digestibility of the silages. The second trial was conducted with the silage samples supplemented with ground leucaena. The supplementation was done at 15% of the total dry matter of substrate. Half of a gram of mixed sample (ground silage & ground leucaena) was placed in the flask and digestion trial was conducted with three replications tor each treatment, DM and OM digestibilities were deter- mined by calculations.

Achievement/Findings:

The average values for dry matter digestibility of the silages supplemented with leucaena were compared with those of the ensiled straw without supplementation. It was found that the values of the earlier experiment were lower than those of the latter. Similar results were also observed with organic matter digestibility. The reason was thought to be the presence of toxic factor in leucaena leaves or the incompatibility of leucaena with silage,
