Abstract


There are small number of tables that show digestibility and energy contents of compound feeds produced by feed factory in different regions of Turkey. Thus, in this paper, four different compound feed types (dairy cattle, beef cattle, calf and lamb growing feeds), totalling 78 compound feeds were analysed to determine their feeding value, dry matter (DM), organic matter (OM) digestibility and energy content (digestible energy (DE), metabolisable energy (ME) and net energy for lactation (NEL). As a result of this study, the crude fiber (CF) levels were higher than standard values in calf and lamb compound feeds and beef cattle compound feeds; however, in the dairy cattle and calf and lamb compound feeds, the crude protein (CP) values were lower than standard values. These findings are considered highly important for the region’s animal feeding. According to our results, the compound feeds for dairy cattle and lamb being used for ruminant nutrition in Diyarbakir Province of Turkey were found to have low nutrient qualities; however, in the calf feed both the metabolisable energy level and nutrient quantities were low.
