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.

Effects Of Interleukin 1(Il1)-Induced Matrix Breakdown On Chondrocyte Morphology In Bovine Nasal Cartilage Explants, Di̇dem L. Kozaci, Gülgün Oktay, Anthony P. Hollander

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to investigate the influence of matrix loss on regulating chondrocyte phenotype, and the synthesis and activation of collagenolytic enzymes. IL1 was used to enhance matrix breakdown in bovine nasal cartilage explants. Change in matrix composition and its effects on chondrocyte morphology were investigated using histochemical techniques. In bovine nasal explants, chondrocytes responded to IL1 to manifest 2 distinct patterns of cell shape exhibiting either pyknotic or enlarged nuclei. Enzyme activity analysis suggested a positive correlation between collagenolytic activity and the occurrence of proteoglycan loss and cell morphology changes. These data suggest that loss of …

Immune Responses In Mice Immunized Intranasally With Sendai Virus, Gazim Bizanov, Irena Jonauskiene

Turkish Journal of Veterinary & Animal Sciences

Mice were immunized 3 times intranasally (i.n.) at intervals of 2 weeks with a formalin-inactivated Sendai virus (SV) whole virus with and without whole formalin-inactivated Bordetella pertussis (Bp) as adjuvant. The antibody response to SV was measured using the hemagglutination inhibition (HI) test in serum, and the IgA and IgG antibodies were evaluated using enzyme linked immunosorbent assay in saliva and serum. It was demonstrated that repeating immunizations with SV plus Bp could induce HI serum antibodies, IgA and serum IgG antibodies. However, in mice immunized subcutaneously with SV alone, high serum IgG antibodies and HI titers were induced only. …

Turkish Journal of Veterinary & Animal Sciences

This study was carried out in Gözlen Creek, located on the Fethiye-Muğla boundary Turkey, between March to July, 1998, and January to July, 1999. Elvers were collected using trap-nets, drift nets, hand scoop nets and electrofishing equipment. Examination indicated that the highest yield was obtained using hand scoop nets (P < 0.05) and electrofishing equipment. Elvers entered Gözlen Creek between February and July. A total of 214 specimens entering the creek were examined and 3 different groups were established according to their morphological characteristics: average weight (W) group I; 0.166 ± 0.007 g, group II; 0.392 ± 0.02 g, group III; 0.800 ± 0.06 g and average total length (L) group I; 56.16 ± 0.06 mm; group II; 64.39 ± 0.11 mm and group III; 82.02 ± 0.18 mm. The length-weight relation of elvers was calculated using regression analysis and was determined as follows: group I; W = 0.0020*L^{2.5327}, group II; W = 0.0015*L^{2.9516}, and group III; W = 0.0023*L^{2.7090}. The condition factor (C) was determined as 0.209 ± 0.009 for group I; 0.154 ± 0.004 for group II and 0.251 ± 0.009 for group III.

The objectives of this study were to determine the chemical composition, digestibility, in situ N kinetics, and by-pass protein contents of 4 different common vetch varieties grown under irrigation. Four different common vetch varieties (Emir 20/1, Nilüfer 17/1, 28/1, and Uludağ 31/4) with different characteristics were selected. The vetch plots were planted on June 15 2002 and each variety was randomly assigned to 3 replications. The vetches were harvested by hand using a clipper on September 11. All samples were analyzed for dry matter (DM), ash, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent …
