Growth Performance And Body Composition Of Kutum Fingerlings, Rutilus Frisii Kutum (Kamenskii 1901),In Response To Dietary Protein Levels, Ghaffar Ebrahimi, Hossein Ouraji
Growth Performance And Body Composition Of Kutum Fingerlings, Rutilus Frisii Kutum (Kamenskii 1901),In Response To Dietary Protein Levels, Ghaffar Ebrahimi, Hossein Ouraji
Turkish Journal of Zoology
A feeding trial was conducted to determine the optimal dietary crude protein requirement for Rutilus frisii kutum fingerlings. Five isoenergetic experimental diets were formulated to contain graded levels of protein (32%, 37%, 42%, 47%, and 52%). Triplicate groups of 80 kutum (average weight 0.5 g) were stocked in 250-L tanks and fed to apparent satiation 3 times a day for 8 weeks. The results indicate that the growth performance and feed utilization of kutum were significantly (P < 0.05) affected by dietary protein level. The second polynomial regression of weight gain against protein level yielded an estimated optimal dietary protein requirement of 41.6%. Weight gain, specific growth rate, and feed efficiency increased with increasing the dietary protein level from 32% to 42%, but decreased significantly (P < 0.05) with further increases in dietary protein. The protein efficiency ratio was inversely correlated with dietary protein level. Feed intake was not affected (P > 0.05) by dietary protein level. No significant difference was found in the whole-body protein, lipid, moisture, or ash contents of fish fed the …
On The Life History Of Spirlin Alburnoides Bipunctatus (Bloch, 1782) In The Qanat Of Uzineh, Northern Iran, Rahman Patimar, Mohsen Zare, Mehdi Hesam
On The Life History Of Spirlin Alburnoides Bipunctatus (Bloch, 1782) In The Qanat Of Uzineh, Northern Iran, Rahman Patimar, Mohsen Zare, Mehdi Hesam
Turkish Journal of Zoology
Within the wide distribution of spirlin in Iran, populations of this species inhabit a great variety of habitats, including qanats. We hypothesized that qanats may contribute to habitat-specific variation in the life history of the fish. To test this, a total of 240 specimens of Alburnoides bipunctatus, caught in the qanat of Uzineh (northern Iran) from October 2007 to August 2008, were examined for life history attributes. The population had a 5-year life cycle. The weight-length relationship (WLR) was estimated as W = 0.0068TL^{3.2559} for males, W = 0.0079TL^{3.2067} for females, and W = 0.0072TL^{3.2387} for the population, having a …
Survival And Growth Of Common Carp (Cyprinus Carpio L.) Exposed To Different Water Ph Levels, Mohammad Saeed Heydarnejad
Survival And Growth Of Common Carp (Cyprinus Carpio L.) Exposed To Different Water Ph Levels, Mohammad Saeed Heydarnejad
Turkish Journal of Veterinary & Animal Sciences
The aim of the present study was to examine the survival and growth performance of common carp (Cyprinus carpio L.) in water with different pH values. Carp (17.8 ± 1.21 cm; 52.14 ± 7.13 g) were transferred to 21 tanks previously adjusted with 7 different pH values: 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, and 9.0. Each value had 3 replicates, and all experiments lasted for 21 days. The survival and growth of carp were assessed at days 7, 14, and 21. At the end of the 21 days, greater weight, length, survival, and biomass were found for pH values of …
Effect Of Dietary Energy Intake And Somatotropin Administration After Weaning On Growth Rate And Semen Characteristics Of Granadina Goat Bucks, Miguel Mellado, Cesar A. Meza-Herrera, Jose R. Arevalo, Jose E. Garcia, Francisco G. Veliz
Effect Of Dietary Energy Intake And Somatotropin Administration After Weaning On Growth Rate And Semen Characteristics Of Granadina Goat Bucks, Miguel Mellado, Cesar A. Meza-Herrera, Jose R. Arevalo, Jose E. Garcia, Francisco G. Veliz
Turkish Journal of Veterinary & Animal Sciences
Twenty-eight growing Granadina goat bucks, divided into 4 groups of 7, in a 2 × 2 factorial arranged design, were used to study the effect of post-weaning levels of dietary energy and administration of recombinant bovine somatotropin (rbST) on growth and semen characteristics. Every 14 days, bucks were offered sustenance at rates of either 1.0 (standard diet, 2.36 Mcal EM kg^{-1}; 15% CP) or 1.25 (increased diet, 2.95 Mcal EM kg^{-1}; 18% CP) times the requirements for growth energy and protein, for a total of 99 days and in combination with or without subcutaneous administration of 125 mg rbST. The …

Turkish Journal of Veterinary & Animal Sciences
A 12-week feeding trial was conducted with rainbow trout fry (initial weight of 1.57 ± 0.01 g) to examine the effects of partial substitution of canola meal in prepared diets on growth, feed conversion ratio (FCR), nutrient digestibility, somatic indices, and survival rate. Five isonitrogenous (44% crude protein) and isocaloric (4000 kcal/kg digestible energy) diets were formulated to contain 8%, 16%, 24%, and 32% canola meal against no canola meal (control group). A total of 375 rainbow trout were distributed into 5 experimental groups with 3 replicates. At the end of the experiment, the fish that were fed diets containing …
