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.

Effects Of Different Diets On The Growth Performance, Gonad Development And Body Composition At First Sexual Maturity Of Rainbow Trout (Oncorhynchus Mykiss), Devri̇m Memi̇ş, Hüseyi̇n Gün

Turkish Journal of Veterinary & Animal Sciences

Rainbow trout Oncorhynchus mykiss with an initial mean weight of 174 g (1+ year old) were fed on 3 different commercial diets (1 extruded pellet and 2 steam pellet) in the same environmental conditions until their first spawning. Changes in growth performance (weight gain, condition factor, specific growth rate and feed conversion rate), gonadosomatic index (GSI), hepatosomatic index (HSI) and body composition (protein, lipid, ash and dry matter) were investigated. The mean weight gain and condition factor for fish fed the extruded diet was significantly greater than for those fed the steam pellet diets (P < 0.05 ). There were no significant differences in specific growth rate, mean length increments and feed conversion rate among the groups, although the feed conversion rate for the extruded diet was slightly lower than the others. The HSI of the group fed an extruded diet was significantly greater than those of the others ( P < 0.05 ). The GSI values of female and male fish at the end of the study (October) did not differ significantly among the groups. Similarly, diet had no significant effects on the muscle composition of the trial fish, except that the muscle lipid of the group fed the extruded diet was significantly higher than those of the other groups (P < 0.05).

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 …

Turkish Journal of Veterinary & Animal Sciences

Quality changes in anchovy caught at different times during storage at ambient and refrigerated temperatures were investigated in 3 different batches. Sampling was carried out each day during storage. The results showed no significant differences among the anchovy batches except for bacteriological counts and trimethylamine (TMA) values at refrigerated temperatures. Storage time and temperature had a significant effect (P < 0.001, P < 0.05) on sensory, bacteriological and chemical values. Bacteriological counts and chemical values increased significantly (P < 0.05, P < 0.001) depending on time, while sensory results decreased (P < 0.05). According to sensory results, samples were acceptable for 1 day at ambient temperatures and for 2 days refrigerated. This study showed that refrigeration did not extend the shelf-life of fresh anchovies by more than a day compare to ambient temperature.

In the first experiment, follicles 90-120 µm in diameter, from 21-day old mice, were dissected mechanically and cultured individually for 7 days. Follicles were subjected to 4 different treatments. Follicles in medium without amino acids and gonadotrophins were assigned as control groups. Follicles in medium with PMSG and without amino acids constituted a positive control whereas the other treatments were test groups. Every 24 h follicle diameters were measured and the …

Because of the interaction between nitric oxide (NO) and the superoxide anion radical, the effect of ischemia-reperfusion on intestinal contractility regulated by the nitrergic system was investigated in the present study. The study was performed on 3 groups of rabbits: group 1, ischemia; group 2, ischemia and 1 h of reperfusion; group 3, ischemia and 24 h of reperfusion. Tissue samples were obtained from ischemic, ischemia-reperfused and adjacent uninjured intestines as study and control samples. The effects of atropine, tetrodotoxin, L-NAME and L-arginine on the intestinal response to electrical field stimulation (EFS) were investigated. Guanethidine was used to minimize adrenergic …
