The Effects Of Urea And Molasses Addition Into Corn Harvested At Early-Milk Stage On Silage Quality And Digestible Dry Matter Yield, Ni̇hat Denek, Suphi̇ Deni̇z Jan 2004

The Effects Of Urea And Molasses Addition Into Corn Harvested At Early-Milk Stage On Silage Quality And Digestible Dry Matter Yield, Ni̇hat Denek, Suphi̇ Deni̇z

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the effects of the addition of 0.5% urea or 0.5% urea plus 4% (w/w) molasses into corn varieties (Rx-947, 33-94, Frassino, and Arifiye) harvested at the early-milk stage on silage quality, in vitro digestibility and digestible dry matter (DM) yield. The addition of urea into silage increased the CP content (P < 0,05). The neutral detergent fiber and acid detergent fiber contents of the control silages were 69.40 and 38.68 for Rx-947, 69.34 and 38.69 for 33-94, 62.67 and 34.93 for Frassino, and 64.35 and 37.04 for Arifiye (P < 0,05). The addition of urea or urea plus molasses into silage increased the silage pH in all varieties, except for Rx-947 (P < 0,05). The lactic, acetic, propionic and butyric acid contents of the silage samples were between 23.2 and 153.3, 7.8 and 23.4, 0.6 and 1.6, and 0.0 and 0.54 g/kg DM, respectively. The addition of urea or urea and molasses into Rx-947 and Frassino varieties and the addition of urea only into the 33-94 variety increased silage lactic acid levels. The addition of urea and molasses into Rx-947, Frassino and Arifiye varieties also increased silage acetic acid levels (P < 0,05). There was a significant difference only between the Frassino and Arifiye varieties on this parameter (P < 0,05). The addition of urea only into silage decreased DM digestibility; the addition of molasses with urea, however, eliminated this negative effect of urea on digestibilit in all varieties, except for Frassino (P < 0,05). Digestible DM yields of untreated silage were 863.68, 1142.43, 1044.43, and 1075.07 kg/decare (10 decares = 1 hectare) for Rx-947, 33-94, Frassino and Arifiye, respectively (P < 0,05). The digestible DM yield of untreated Rx-947 silage was significantly lower than those of the others (P < 0,05). It can be concluded that corn varieties harvested at the early-milk stage (20% DM) can be ensiled, and that urea and molasses can be used as silage additive to increase CP and energy content of silages.

Turkish Journal of Veterinary & Animal Sciences

The objectives of this study were to examine the botanical composition and determine the nutritive value of pastures in 9 different locations in Kars district with respect to stages of maturity. Samples were collected bi-weekly from 21 May to 30 July 1999. The Gramineae, Leguminoseae and other plant families constituted 64.2, 22.8 and 13.0% of the plant population, respectively. There was a variation in the nutrient composition of samples collected from different locations (P < 0.05). Average dry matter (DM) content was 28.8% and concentrations of organic matter (OM), crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), nitrogen-free extract (NFE), ether extract (EE) and ash on a DM basis were 90.8, 15.3, 30.0, 57.6, 43.4, 2.0 and 9.2%, respectively. Stage of maturity altered nutrient composition (P < 0.5). Concentrations of OM, NFE and ash did not change, CP linearly decreased, and CF and NDF quadratically increased with advancing maturity. In conclusion, the Gramineae were the predominant flora of pastures in northeastern Turkey. Moreover, mathematical models developed to characterize changes in the nutrient composition of pastures with advancing maturity may help to improve current feeding strategies.

Turkish Journal of Veterinary & Animal Sciences

The influence of 2 enzyme supplements for diets based on wheat with high or low viscosity on performance and some intestinal parameters of male broiler chickens were investigated. The experiment was of 2 x 3 factorial design, with 2 types of wheat (high or low viscosity) and 3 enzyme treatments (none, Avizyme 1300-xylanase or Avizyme 1500-amylase). Ileal digesta viscosity was significantly (P < 0.029) higher in birds fed with high viscous wheat than with low viscous wheat. Ileal digesta viscosity (P < 0.001) and dry matter content (P < 0.002) were significantly reduced by both enzyme preparations. Body weight gain, feed intake, dry matter intake, feed conversion ratio, DM retention and wet or dry excreta output were not significantly (P > 0.05) affected by all treatments. There were no significant interactions (P > 0.05) between the effects of wheat type and enzyme supplementation. In conclusion, the supplementation of high or low viscous wheat-based diets with the enzyme preparations of amylase …

Effects Of H^+-K^+ Atpase Inhibitors (Omeprazole And Lansoprazole) On Fertilization-Induced Bioelectrical Potential Changes In The Egg Of The Frog, Rana Cameranoi, Şeref Erdoğan, Kerem Tuncay Özgünen, Tuncay Özgünen

Turkish Journal of Veterinary & Animal Sciences

Fertilization triggers Ca^{2+} increase and alkalization in the eggs of some species such as the frog. Ooplasmic Ca^{2+} increase triggers fertilization potential (FP), and alkalization can have a permissive effect in Ca^{2+} increase. It can be expected that pH regulation in the egg can affect both ooplasmic Ca^{2+} levels and the events triggered by increasing Ca^{2+}. The evidence of the possibility of H^+-K^+ ATPase in different tissues in recent studies prompted us to wonder about the probability of the existence of this pump in the egg. Therefore, we decided to investigate the presence of H^+-K^+ ATPase by bioelectrical potential recordings …

A New Medium From Ram Horn Hydrolysate For Enumeration Of Aerobic Bacteria, Esabi̇ Başaran Kurbanoğlu, Ö. Faruk Algur

Turkish Journal of Veterinary & Animal Sciences

A new medium prepared from ram horn hydrolysate was utilized for the enumeration of aerobic bacteria from environmental samples. First, horns were ground and 35 g of horn flour was hydrolyzed chemically. The hydrolyzed material was completed to 400 ml with deionized water and this resulting solution was termed ram horn hydrolysate (RHH). It was found that it has both organic and inorganic materials sufficient for use as a bacterial medium. The RHH was enriched by the addition of glucose, yeast extract and KH_2PO_4. The effects of different concentrations (1 to 10% v/v) of RHH on the growth of bacteria …
