Turkish Journal of Veterinary & Animal Sciences
This investigation was carried out in order to simultaneously compare various production traits of Saanen x hair crossbred goats and pure hair goat flocks under rural environmental conditions. Fecundity, fertility and infertility values for Saanen x hair crossbred and pure hair goats were 1.25, 1.30 and 4.47%, and 0.72, 0.79 and 21.00%, respectively. The effects of genotype, year and age on fecundity, fertility and infertility for Saanen x hair crossbred and pure hair goats were significant (P < 0,01). Birth and weaning weights for Saanen x hair crossbred and pure hair kids were 3.70 kg and 2.63 kg, and 14.68 kg and 12.12 kg, respectively. The effects of genotype, year and age on the birth and weaning weights for Saanen x hair crossbred and pure hair kids were significant (P < 0.01, P < 0.05, respectively). The survival rates for Saanen x hair crossbred and pure hair kids were 95.76% and 78.61%, respectively. Daily average milk yield, lactation length and lactation milk yield in Saanen x hair crossbred and pure hair goats were; 1.83 kg, 201.5 days and 201.77 kg, and 0.56 kg, 143.7 days and 80.47 kg, respectively. The effects of genotype, year and age on the daily average milk yield, lactation length and lactation milk yield for Saanen x hair crossbred and pure hair goats were significant (P < 0.01).

Turkish Journal of Veterinary & Animal Sciences
This study is based on the examination of 759 chubs from Karasu River (40° 45´ 33´´ E, 39° 56´ 16´´ N) between November 1995 and October 1997. This population comprised seven age groups of males and nine of females. The second age group was dominant in the population. Individuals were composed of 50.46% males and 49.54% females. The male and female ratio was 1:1.019 (M:F). The Von Bertalanffy growth parameters and length-weight relationships were; L_t = 35.8765 (1-e^{-0.1241(t+1.16660)}), W_t = 583.2981 (1-e^{-0.1241(t+1.16660)})^{2.952}, W = 0.0150 FL^{2.952} in males and L_t = 41.4154 (1-e^{-0.1160(t+1.3207)}), W_t = 936.3338 (1-e^{-0.1160(t+1.3207)})^{2.980}, W = 0.0142 …

Growth Performance, Body Traits And Fillet Composition Of The European Sea Bass (Dicentrarchus Labrax) Reared In Various Salinities And Fresh Water, O. Tufan Eroldoğan, Meti̇n Kumlu
Turkish Journal of Veterinary & Animal Sciences
The effects of various salinities and fresh water (FW) (0.4 ppt) on the growth performance, body traits and fillet composition of juvenile and young sea bass (Dicentrarchus labrax) in FW were investigated in two separate experiments in this study. In Experiment 1, following acclimation, sea bass juveniles (9.5 ± 0.5 g) were reared in 240-L fibreglass tanks (40 x 40 x 150 cm) for 90 days in five different treatments (FW, 10, 20, 30 and 40 ppt). The fish cultured in FW, 10 and 20 ppt grew better than those at 30 or 40 ppt (P < 0.05). Salinity did not affect the crude protein, lipid or ash content of the fish (P > 0.05). Yet, the dry …

The Effect Of Concentrate Feeding Levels On The Postweanining Performance Of Holstein Friesian Calves, Mete Yanar, Olcay Güler, Bahri̇ Bayram
Turkish Journal of Veterinary & Animal Sciences
The influences of different levels of concentrate on the growth characteristics of Holstein Friesian calves reared under an original calf-rearing program were investigated in this study. Forty-one new-born calves (20 male and 21 female) were allocated to the four concentrate groups: 2, 2.5, 3 kg/calf and ad libitum. The calves were weaned at 5 weeks of age, and the trial lasted for 6 months. The results with regard to weights at 6 months of age revealed that an increasing amount of concentrate supplementation resulted in a significantly (P < 0.01) higher live weight. Furthermore, daily weight gains between birth and 6 months of age was also significantly higher (P < 0.01) in the ad libitum group than in the 2, 2.5 and 3 kg/day groups. The highest overall gains in body measurements, for example body length and heart girth, were obtained from calves fed concentrate ad libitum. However, feed efficiency ratios were not significantly influenced by the various amounts of concentrate offered to calves. The overall results suggest that the appropriate level of concentrate for the new calf-rearing program should be ad libitum.

Growth And Mortality Of Mussels ( Mytilus Edulisl.) Reared Inlantern Nets In Loch Kishorn, Scotland, Sedat Karayücel, Ismi̇han Karayücel
Turkish Journal of Veterinary & Animal Sciences
One-year old rope grown mussels ( Mytilus edulis L.) were held in experimental lantern nets at 2 m and 6 m depths in Loch Kishorn on the west coast of Scotland. Growth, mortality and shell morphology were monitored from May 1993 to August 1994. Water temperature, salinity, transparency and food availability were also determined. These showed a clear seasonal cycle, in consequence, growth of mussels was relatively rapid from May to November and very slow during the rest of the year. Depth had a insignificant effect on shell length and tissue growth (P>0.05) due to similar environmental factors. Shell …

Growth Rate Of Thoroughbreds: Effect Of Age Of Dam, Year And Month Of Birth, And Sex Of Foal, R. L. Hintz, H. F. Hintz, L. Dale Van Vleck
Department of Animal Science: Faculty Publications
Weight, height, and cannon bone measurements were obtained on 1,992 Thoroughbred foals. Colts were heavier than fillies at birth and the differences increased with age. Dams under 7 years of age and older than 11 years had foals of lighter weight at birth than mares 7 to 11 years of age and the differences persisted at 510 days of age. Foals born in April, May, or June were heavier than foals born in January, February, or March. Year of birth also influenced body weight. The trends for height at withers and cannon circumference were similar to those of body weight.
