Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to determine the effects of formic acid, molasses, and microbial inoculant (homofermentative lactic acid bacteria) as silage additives on silage quality and ruminal fermentation characteristics. Silages with or without formic acid (0.5%), molasses (5%), or microbial inoculant (10 g/t) were fed to ruminally cannulated, 1.5 year-old Kıvırcık x Morkaraman sheep. Silage treated with molasses had significantly greater DM and CP concentrations compared with other groups (P < 0.05). pH values did not significantly differ among treatments (P > 0.05). Lactic acid concentrations were significantly higher in silages treated with enzyme or molasses compared with others (P < 0.05). While acetic acid concentration was the highest in silage treated with acid, it was the lowest in silage treated with molasses (P < 0.05). Silage NH_{3}-N concentration was the highest in silage treated with molasses, but the lowest in silage treated with acid (P < 0.05). Post-feeding ruminal total organic acid concentrations were significantly greater in sheep fed silages with additive than the control (P < 0.05). While percentages of acetic acid were greater, percentages of butyric acids were less in the rumen fluid of sheep fed silage without additive compared with the rumen fluid of sheep fed silage treated with silage additives. However, percentages of propionic acid did not differ among treatments.

Turkish Journal of Veterinary & Animal Sciences
Wheat straw, barley straw, alfalfa hay, alfalfa silage and maize silage were offered ad libitum to three male sheep, and daily dry matter intake (DMI) and apparent dry matter digestibility (DMD) were measured. Samples of forages were incubated with rumen fluid to determine gas production. Gas productions were measured at 3, 6, 12, 24, 48, 72 and 96, and gas production constants (a, b, c,) were described using the equation y = a + b (1 - e-^{ct}). Gas production at all incubation times and gas production constants (c, b and a+b) were significantly (P < 0.001) correlated to DMD or DMI. Although the gas production constant c explained 74% of the variation of DMD, the gas production constant b explained 92% of the variation of DMD. The gas production constants c and (a+b) in combination explained 96% of the variation of DMD. The gas production constants b and c alone explained 70% and 78% of the variation of DMI respectively. The gas production constants in combination explained 84-90% of the variation of DMI. It was concluded that the accuracy of predicting DMD or DMI can be increased when gas production constants are used in combination, and the in vitro gas production technique has good potentiality to predict DMD and DMI.

Turkish Journal of Veterinary & Animal Sciences
This study was carried out to investigate the effects of hatching egg weight and length of egg storage period on hatchability and subsequent laying performance of quails. Eggs were collected from a quail flock (Coturnix coturnix Pharaoh) aged 17 weeks and classified into 4 groups on the basis of storage period 1, 3, 5, or 7 d. Prior to egg storage, the eggs in each group were further divided into egg weight treatment (small: 12.51 g). Hatchability of total and fertile eggs was affected significantly by hatching egg weight (P < 0.05) but was not affected significantly by the length of egg storage period. There was a decrease in egg production associated with increase in hatching egg weight. Egg production of quails hatched from stored eggs for 3 days was greater than the other groups. There was a significant interaction between hatching egg weight and length of egg storage for egg production. It was concluded that medium eggs can be hatched satisfactorily after 3 days storage for optimum egg production in quails.

The objective of the present study was to describe some reproductive parameters, hormonal levels and some biochemical properties of blood serum in rams under the Afyonkarahisar province conditions. Semen (via an artificial vagina) and blood were collected five times during the breeding season from a total of 10 mature and healthy fat-tailed rams (Akkaraman and Awassi) in Afyonkarahisar. Breed effects were significant for relative testes volume, sperm concentration, percentage of abnormal spermatozoa, triiodothyronine (T_{3}), albumin/globulin ratio, total lipid (P < 0.05) and cholesterol (P < 0.01). Some reproductive parameters and biochemical properties of Akkaraman and İvesi rams indicated that the values were recorded in the optimum range during the breeding season under Afyonkarahisar conditions. In addition, some reproductive parameters of rams show a correlation with some biochemical and enzymatic properties.
