Abstract:
Lucerne was ensiled either by the conventional wilting process (WL) or as a mixture of 80% fresh lucerne + 20% ozonated cotton stalks (L + OCS), and the effect of feeding these silages to dairy cows on performance and on the digestibility of ration carbohydrate constituents was examined. Ten cows in mid-lactation were divided into two equal groups with similar performance data at the onset of the experiment, and fed ad libitum for 28 days total mixed rations composed of 70% concentrate, 15% lucerne hay and 15% of either WL silage or L + OCS silage. Average daily milk yields during the experimental period were 27.1 and 27.6 kg in the WL and L + OCS groups, respectively, and the L + OCS cows gained higher body weight. Milk composition was similar in both treatments. The WL silage had a lower content of neutral detergent soluble (NDS) glucose, neutral detergent fibre (NDF) glucose and NDF xylose, and a higher content of arabinose, galactose and mannose than L + OCS silage. Carbohydrate digestibility was 83 and 85% in the WL and L + OCS rations, respectively. NDF digestibility was similar (45.0%) in both rations; however, digestion of NDF glucose, xylose and total polysaccharides was slightly higher in the L + OCS group than in the WL ration. In both rations, NDF glucose was more digestible than NDF xylose and NDF uronic acid and less digestible than NDF arabinose, galactose and mannose. Digestibility of total NDS carbohydrate was 89% in WL ration and 91% in L + OCS ration, and in both groups, digestion of NDS mannose and galactose was lower than that of NDS glucose, arabinose and pectin. Data of this study indicate that a direct-cut and ensiled lucerne silage made of L + OCS is equivalent to lucerne haylage as a component in lactating cow rations. © 1995 Elsevier Science B.V.

Ozonated cotton stalks as a silage additive: Digestion of total and cell wall monosaccharide constituents of lucerne based dairy cows rations
Lucerne was ensiled either by the conventional wilting process (WL) or as a mixture of 80% fresh lucerne + 20% ozonated cotton stalks (L + OCS), and the effect of feeding these silages to dairy cows on performance and on the digestibility of ration carbohydrate constituents was examined.

Average daily milk yields during the experimental period were 27.1 and 27.6 kg in the WL and L + OCS groups, respectively, and the L + OCS cows gained higher body weight. Milk composition was similar in both treatments. The WL silage had a lower content of neutral detergent soluble (NDS) glucose, neutral detergent fibre (NDF) glucose and NDF xylose, and a higher content of arabinose, galactose and mannose than L + OCS silage. Carbohydrate digestibility was 83 and 85% in the WL and L + OCS rations, respectively. NDF digestibility was similar (45.0%) in both rations; however, digestion of NDF glucose, xylose and total polysaccharides was slightly higher in the L + OCS group than in the WL ration.
