(Kafkas Univ, veteriner Fakultesi dergisi, 2010) Aksoy, Ihsan; Nursoy, Huseyin
Hungarian vetch intercropped with wheat (50%:50%) planted at dryland in Autumn. and were harvested 7 times at 1 wk intervals throughout mid June and late July. The aim of study was to determined the effects of varying harvested of the mixture on nutrient content in vitro digestibility. relative feed value (RFV) and rumen degradation kinetics. While harvest effect did not differ hay of Hungarian vetch + wheat on dry matter (DM), ash and organic matter, NDF and ADF ratios increased, and the crude protein ratios increased up to July. 20 degradabilities were determined between 30.10-53.24% and its were statistically decreased with increasing maturity (P<0.01). Forage yield 1385-1643 kg/da. dry herbage yield 363-654 kg/da and dry matter yield 344-621 kg/da were throughout harvesting period. Forage yield increased significantly as from July. 6 the harvesting stage (P<0.01). in vitro dry matter digestibilities of the mixtures hay declined rapidly because of maturity from first harvesting to end harvesting (P<0.01). RFV of the mixtures were determined between 106-180. The DM degradabilities in rumen decreased with delaying harvest of the mixtures. Degradation rates of the mixtures were not statistically founded between 0.015-0.033 h-1. Effective DM degradabilities were determined between 30.10-53.24% and its were statistically decreased with increasing maturity (P<0.01). In conclusion, according to investigated parameters 30.10-36.68% of DM of Hungarian vetch and wheat mixtures or milk stage of wheat seemed to be the best harvesting stage for forage.

In this study, the effects of CaCl2 (2%) supplemented diet, rock salt (RS, 2%) supplemented diet and control diet (no supplement) on the weight gain, specific growth rate, daily feed intake, feed conversion rate, protein efficiency rate and serum mineral concentration (Na, K, Cl) were investigated in rainbow trout. RS was used for increasing the CAD and Na/K ratio of the control diet and CaCl2 was used for decreasing the CAD level of the control diet. A total of 300 fish, 2 replications for each treatment consisting of 50 fish with a mean initial body weight of 88.2 g were used in the experiment. The experiment lasted fifteen weeks. The diet supplemented with 2% RS improved significantly the weight gain, feed conversion rate and protein efficiency rate in rainbow trout compared to 2% CaCl2 supplemented group and control (P<0.05). Dietary RS supplementation also improved the specific growth rate and daily feed intake. However, this improvement was not statistically significant (P>0.05). Dietary 2% CaCl2 supplementation did not significantly affect the weight gain, specific growth rate, daily feed intake, feed conversion rate and protein efficiency rate in rainbow trout compared to control diet (P>0.05). Na, K and Cl level of the serum and mortality rate were not statistically different among the groups (P>0.05). The dietary 2% RS supplementation produced a better growth and feed efficiency for rainbow trout compared to dietary 2% CaCl2 supplementation and control diet. Added RS to diet was appropriate for making cationic the diet and increasing the CAD level and Na/K ratio of diet.

The effects of 12 different diets which regulated 0.1-0.7 mol Na/K ratio and 176-422 mEq/kg Dietary Electrolyte Balance, DEB, (Na+K-Cl) were investigated on growth, blood gases, hematological variables, biochemical parameters and carcass traits in broiler chickens. Two-day old Ross-308 male chicks (n=180) having individual thirty replicates for 6 groups were used and the study lasted 42 days in the experiment. The S group diet was based on corn and soybean meal and 0.25% salt. This group diet was accomplished by adding 1-0.5% NH4Cl as A1 and A2 of anionic groups and 0.5-1-1.5% NaHCO3 as C1, C2 and C3 of cationic groups in starter and grower phases, respectively. Increasing Na/K and DEB of the diets had no effect on live weight, body weight gain and feed per gain in 0-42 days (P>0.05). Blood pH quantitatively increased in S, C1 and C2 groups (P<0.05). A1, A2 and S groups of pO(2) levels were higher than those of cationic groups (P<0.05), (R-2=0.59). The values of HCO3-, HCO3std, TCO2, BEecf, Be(b), Hct and THbc were lower anionic groups than cationic groups (P<0.05), (R-2=0.63-0.82). SO2c level was the lowest in C1 group (P<0.05). Anion gaps of the broilers were calculated as 7.97-20.84 mEq/l. Ionized calcium was quantitatively the highest in A1 group. Hot carcass and abdominal fat were not affected by the experimental diets with varying Na/K and DEB (P>0.05). Based on the results of this study, anionic diet such as A1 or 0.1 of Na/K ratio and 212 mEq/kg of DEB could be fed for broilers in case of insufficient Ca. In normal case, it is concluded that C1 and C2 of diets or 0.3-0.5 of Na/K ratios and 259-344 mEq/kg of DEB were appropriate for broilers.
