Effect of Addition of Urea or Urea Plus Molasses To Different Corn Silages Harvested at Dough Stage on Silage Quality and Digestible Dry Matter Yield
(Taylor & Francis Ltd, 2003) Demirel, M; Yilmaz, L; Deniz, S; Kaplan, O; Akdeniz, H
To study the effects of 0.5% urea and 0.5% urea plus 4% molasses addition to different corn silages on its quality, in vitro dry matter digestibility (IVDMD) and digestible dry matter (DDM) yields, four corn cultivars, Arifiye, Frassino, Rx-947 and 3394 harvested at dough stage, were ensiled in cite litre silos for 90 days. Supplement, cultivars interactions were significant for most of the parameters studied, pH of all the silages was within desirable range. Among organic acids, lactic acid was highest in Rx-947, supplementation making no difference. IVDMD was highest in silages Rx-947 and 3394 supplemented either with urea or urea plus molasses. The highest DDM yields were in silages of supplemented or unsupplemented Arifiye and 3394 cultivars followed by Frassino. Thus these three cultivars with or without supplementation are recommended for silage making.
Effects of Varying Levels of Live Yeast Culture on Yield and Some Parameters in Laying Hen Diets
(indian veterinary Journal, 2004) Nursoy, H; Kaplan, O; Oguz, MN; Yilmaz, O
Direct-fed microbes (DFM) include bacteria, yeast or combination of them which are added into diet. They are commonly used to enhance growth rate, feed efficiency and egg yield in poultry rations. Yeast cultures (YC) contain viable yeast, metabolites, and the media on which the yeast cells are grown (Bradley and Savage, 1995). The addition of live yeast cultures to chick diets have been used to improve egg production. (Nahashon et al., 1996), animal performance (Onifade et al., 1998; Purushotha-man and Natanam, 1999), enhance feed-efficiency (Kahraman et al., 1996), improve, fatty acid digestibility, and to reduce abdominal fat content (Lacroix et al., 1991). In contrast, Elbert et al. (1987), Brake (1991) and Lacroix et al. (loc. cit.) have reported no effect of dietary YC in balanced chicken diets. The aim of this study was to assess egg yield and quality in hens fed different levels of yeast culture at last period of laying.
The Possibilities of Using Sugar Beet Pulp Silage Produced by Different Methods in Lamb and Dairy Cow Rations - 1 - Obtaining High Quality Sugar Beet Pulp Silage
(Scientific Technical Research Council Turkey, 2001) Deniz, S; Demirel, M; Tuncer, SD; Kaplan, O; Aksu, T
In this study, how to obtain high quality sugar beet pulp silage was investigated. Sugar beet pulp was mixed with wheat straw or grass hay in order to increase the level of dry matter to 20, 25 and 30%, and 5% molasses and different levels of urea were added (0, 1, 1.5 and 2% for wheat straw containing groups; 0, 0.5 and 1% for grass hay containing groups). The mixed materials were stored in containers of one kg for two months. At the end of the incubation period, the containers were opened and the silages were evaluated by measuring the fermentation characteristics. The crude protein content of the silages increased due to the added urea level. The pH and the amounts of lactic, acetic and butyric acids were found to be between 3.72 and 4.40, 31.17 and 71.51 g dry matter kg(-1), 12.61 and 35.35 g dry matter kg(-1). and 0.06 and 2.56 g dry matter kg(-1). respectively (P<0.05). Finally, it is possible to obtain high quality sugar beet pulp silage by increasing its dry matter content (20-30%) with wheat straw or grass hay and adding sugar beet molasses (5%). Urea supplementation also increases the nitrogen content of silage.
The Possibilities of Using Sugar Beet Pulp Silage Produced by Different Methods in Lamb and Dairy Cow Rations - 2 - Ruminal Degradability
(Tubitak Scientific & Technological Research Council Turkey, 2002) Deniz, S; Bolat, D; Kaplan, O; Nursoy, H
The objective of this experiment was to evaluate the ensiling methods for the more efficient and long lasting preservation of sugar beet pulp which is rich in energy and is a source of inexpensive feedstuff The ruminal degradabilities of these silages were determined Sugar beet pulp was mixed with wheat straw or grass hay and 5% molasses in order to increase the level of dry matter of the silages to 20 25 and 30% In addition at the level of 0 1 1 5 and 2% as well as 0 0 5 and 1 % urea were added to the samples containing straw and grass hay respectively The mixed materials were ensiled in jars (approximately 1 I in volume) for two months All samples were incubated for 4 8 16 24 48 and 72 h in four rumen fistulated rams Each of the samples was incubated in duplicate in the rumen of each ram After a 72 h incubation period the ruminal dry matter degradability of silages containing 20 25 and 30% dry matter were found to be 81 31 73 72 and 70 42% and 81 49 81 09 and 77 19% for the samples containing wheat straw and grass hay respectively The ruminal degradabilities of silage samples were affected negatively by adding different levels of wheat straw in order to increase dry matter content whereas grass hay levels had no effect On the other hand urea supplementation had no effect on ruminal dry matter degradability.
