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.

Effects Of Egg Weight And Length Of Storage Period On Hatchability And Subsequent Laying Performance Of Quail, Meti̇n Petek, Hasan Başpinar, M. Mustafa Oğan, Faruk Balci
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.
