BACKGROUND: The objective of this study was to investigate the effect of polysaccharide-degrading enzymes (a cellulase and a xylanase) alone or in a combination with a bacterial inoculant on fermentation parameters and in vitro degradability and gas production of low-dry matter (DM) alfalfa silage. First cut alfalfa (Medicago sativa L.), harvested at about 5% bloom stage [260 g kg −1 dry matter (DM)] was ensiled in laboratory-scale silos without preservatives or preserved with formic acid, a cellulase (Cell), a xylanase, a cellulose/xylanase enzyme combination (Cell/Xyl), a lactic acid bacteria-based inoculant (Inoc), and a mix of Inoc and Cell (Inoc/Cell). Triplicate silos were opened on days 1, 3, 7, 15 and 60.

An analysis of the Bulgarian livestock development for the period 1990-2010 was made. The major conclusions were as follow: - Bulgarian animal husbandry collapsed during the period 1990 - 2000. After the entry of Bulgaria into the EU there was a trend towards revival. The way out of this crisis depends on an active intervention of the country; - Grants in animal husbandry are insufficient and do not create interest in the livestock development; - It?s necessary to increase the national payments for farmers breeding animals. In this direction may be sought other decisions as well; - Bulgaria's perspectives in the field of animal husbandry are in the following directions: sheep, goat and buffalo breeding, meat cattle and organic farming; - Financial incentives for producers of animal products to construct processing plants; It is imperative to initiate national intervention about returning Bulgaria and its products to markets of Russia, former USSR countries and Arab countries with its specific animal husbandry products.

Abstract:The report contains analysis on the present state, and perspectives for the development of Bulgarian animal husbandry on the eve of the integration with European union.During the period 1990-2000 the animal husbandry in Bulgaria fell into a deep crisis. After this period Bulgarian animal husbandry showed a stable trend for survival.The integration of Bulgaria with EU outlines good perspectives for the development of sheep, goat and beef cattle breeding.Another promising direction is the production of ecologically clean animal products.The development of Bulgarian animal husbandry will depend to a great extent on the reinstatement of the lost Bulgarian markets in Russia, in the countries fom the former USSR (Union of the soviet socialistic republics) and in the Arab countries by offering specific Bulgarian animal products.
