Effects of teat measurement and teat shape on milking time, milk flow rate and milk yield in Brown Swiss cows were evaluated. The means of 305-day milk yield for cylindrical, funnel and bottle teat shape groups were 3156, 3169 and 2377 kg, respectively. The mean values for the milking time in 1st2nd and 3rd milk yield groups were 6.54, 6.56 and 6.20 min and the differences were not statistically significant. Length and diameter of front and rear teats were negatively correlated with milk flow rate. Milk flow rate showed significant correlations with 305-day milk yield and milk yield per milking (P < 0.001). There was a significant negative correlation between milking time and milk flow rate (P < 0.001). In conclusion, 305-day milk yield of bottle teat shape cows was lower than that of cylindrical and funnel teat shape cows. [ABSTRACT FROM AUTHOR]

This study was carried out to determine the carcass traits of geese of different origins reared in Turkey. INRA, Armutlu, Başkuyu and Tatlicak origin geese were used; 6 females and 6 males of each origin were slaughtered at the end of the experiment. Among the origins, the differences were statistically significant for leg weight, head and abdominal fat ratio to the body (P < 0.05), neck weight, feather and gizzard fat ratio to the body (P < 0.01), hot carcass, blood, head, foot, heart, liver, gizzard, cold carcass, wing, breast and back weight, and blood, heart, liver and back ratio to the body were also significant (P < 0.001).

This study was carried out to determine the growth traits of geese of different origins reared in Turkey. In the experiment, 25 INRA, 15 Armutlu, 15 Tatlƒcak and 18 Başkuyu geese were used. The differences between chick weight, and 12th and 25th week live weight of the geese was statistically significant (P < 0.001). Live weight gains were highest at weeks 4 and 5 for the geese. Significant differences were found between the sex groups for week 8, 12, 16, 20 and 25 live weight (P < 0.001). [ABSTRACT FROM AUTHOR]

This study was carried out to determine the hatching traits of geese of different origins reared in Turkey. In the experiment, geese were selected from different regions of Turkey, (Kars-INRA), Isparta-Armutlu, Konya-Ba—kuyu and Konya-Tatlƒcak); 20 female and 4 male 2-year-old geese were used. Egg production was 39.4, 13.0, 11.4 and 12.6 eggs/geese, and egg laying period was 133, 75, 60 and 73 days, respectively. There were statistically significant differences between the original egg weight and hatched chick weight (P < 0.01). Egg weight loss proportions during incubation for the experimental groups were 12.92, 11.44, 11.38 and 12.22%, respectively. [ABSTRACT FROM AUTHOR]

This study was carried out to estimate the phenotypic and genetic parameters for the gestation length and birth weight of Brown Swiss cattle reared at the Bahri Bagdas International Agricultural Research Institute. The experimental material consisted of 891 calving records and 666 gestation length records between 1989 and 2000. The least- squares means of birth weight and gestation length were 35.6 kg and 284 days, respectively. Except for the effect of the dam's age on gestation length, all other factors investigated in this study had significant effects on both gestation length and birth weight (P < 0.05-0.001). The estimations of heritability and repeatability for birth weight were O. 10 and O. 15, respectively. Estimated repeatability for gestation length was 0.14. [ABSTRACT FROM AUTHOR]

This study was carried out to investigate milk yield traits and some environmental factors affecting milk yield traits in Brown Swiss cattle reared at the Bahri Dagdas International Agricultural Research Institute. Between 1987 and 1998, 730 lactation records obtained from 273 cows were evaluated. The least-squares means of measured milk yield, 305-day milk yield, dry period and lactation duration were 3631 kg, 3332 kg, 97.1 days and 313.8 days, respectively. Both year and age statistically affected (P < 0.01-0.001) milk yield and lactation duration, but the calving season was not affected (P > 0.05). The effect of the year on dry period was also significant (P < 0.01), but the effect of age and calving season were not significant (P > 0.05). [ABSTRACT FROM AUTHOR]
