The Effect of Different Enzyme Supplementations on the Performance of Laying Hens Fed With Diets Based on Barley
(Tubitak Scientific & Technological Research Council Turkey, 2003) Yörük, MA; Bolat, D
The effects of replacing corn in the diets of laying hens with 100% barley containing different enzymes as an energy source on different yields and egg quality traits were investigated in this study. A total of 300 laying hens (average 22 weeks of age) were used. The study was carried out with five groups, 2 controls (60% corn, 60% barley) and 3 experimental groups. Each group of 60 hens was also divided into six subgroups. Enzymes such as Betaglucanase (Allzyme BG), xylanase (Allzyme PT) and amylase (Allzyme AB) were separately added at a rate of 0.05% in the order of betaglucanase, betaglucanase + xylanase and betaglucanase + xylanase + amylase to each of the groups fed 60% barley. It was concluded that there were no significant differences among the groups in terms of live weight gain. feed consumption, egg yield. feed conversion efficiency or egg quality traits (egg weight, shell thickness and Haugh units) during the 135-day trial period.
The Effect of Different Enzyme Supplementations on the Performance of Laying Hens Fed With Diets Based on Corn and Barley
(Scientific Technical Research Council Turkey, 2003) Yörük, MA; Bolat, D
This study was carried out to investigate to possibility of replacing corn in the diets of laying hens with 50% barley containing different enzymes as an energy source. A total of 300 laying hens (average 22 weeks of age) were used. The study was conducted with five groups as two controls (60% corn, 30% corn + 30% barley) and 3 experimental groups. Each group of 60 hens was further divided into six subgroups. In the present study, enzymes such as betaglucanase (Allzyme BG), xylanase (Allzyme PT) and amylase (Allzyme AB) were separately added at a rate of 0.05% in the order of betaglucanase, betaglucanase + xylanase or betaglucanase + xylanase + amylase to each of the groups fed 50% barley. The study lasted for 135 days. It was concluded that there were no significant differences among the groups in terms of live weight gain, feed consumption, egg yield, feed conversion rate or egg quality (egg weight, shell thickness and Haugh units) during the 135-day trial period.
Effects of a Bacterial Silage Inoculant on Corn Silage Fermentation and Nutrient Digestibility
(Elsevier Science Bv, 2004) Aksu, T; Baytok, E; Bolat, D
Two type silage were prepared, the control had no additives and the other silage with a bacterial inoculant (BONSILAGE(R). Both of them were stored in 100 kg capacity plastic containers for two months and silage pH, organic acids and nutrient digestibility were investigated. In control and inoculated silage pH were 3.90 and 3.63 (P < 0.05), amount of lactic acid 16.75 and 22.45 9 kg(-1) DM (P < 0.05), acetic acid 49.48 and 51.65 g kg(-1) DM, and butyric acid 7.12 and 5.44 g kg(-1) DM (P < 0.05), respectively. Eight Morkaraman sheeps, 2 years old, were used to determine nutrient digestibility of corn silages. In control and inoculated silages, the degrees of digestibility of DM were 59.73, 68.53%, OM 64.10, 66.95%, CP 48.39, 50.30%, NDF 63.35, 66.11%, and ADF 55.33, 59.35%. In conclusion, corn silage fermentation and digestibility of DM and NDF were increased (P < 0.05) by the bacterial inoculation (C) 2004 Elsevier B.V. All rights reserved.
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.
