    The Comparison of Some Reproductive Traits of Anatolian and F1 Crossbred (Anatolian X Italian) Buffalo under Village Conditions In Turkey
    (Int Buffalo Information Ctr, 2013) Sekerden, Ozel
    This study compared reproductive traits of Anatolian and Anatolian x Italian F-1 crossbred buffaloes in Ilikpinar Village of Kirikhan District of Hatay Province, Turkey. Previous studies of the same genotypes compared growth characteristics, and milk yield and somatic cell numbers in milk, and this present study has dealt with some reproductive traits. The study material involves various breeding records of Anatolian and Anatolian x Italian crossbred female buffaloes. The buffalos in various lactation orders were from two units representing buffalo herds of Ilikpinar Village. The records cover periods: 2001-2011 and 2003-2011, respectively, for Anatolian and crossbred buffaloes. The numbers of Anatolian and F-1 crossbred buffaloes in terms of trait and genotype were respectively 12 and 10 for first calving age; 87 and 21 for calving interval; and 20 and 5 for gestation period. The effects of genotype and calving year on examined features were determined by GLM variance analysis and mean values were calculated using SPSS Program. It was concluded that there was no significant difference between Anatolian and Anatolian x Italian F-1 crossbreeds in terms of the examined reproductive traits.

    Effective Environmental Factors on Milk Composition, Rennet Coagulation Time and Urea Content of in Anatolian Buffaloes Milk of Ilikpinar Village Hatay Province
    (Int Buffalo Information Ctr, 2013) Sekerden, Ozel; Avsar, Yahya Kemal
    The objectives of this study were to investigate determining environmental factors on composition, renneting time, urea concentration, acidity, density and pH of Anatolian Buffaloes milk. As a total of 115 milk samples from 53 cows that were calved in 2004 and 2005 in 8 units of Ilikpinar Village were collected in morning milkings in June, September, December and March. The cows were on their lactation days 30 +/- 15, 60 +/- 15, 90 +/- 15, 120 +/- 15, 150 +/- 15, 180 +/- 15, 210 +/- 15, 240 +/- 15 and 270 +/- 15. The milk samples were analysed for total dry matter, fat, protein, ash, density, pH, acidity, renneting time and urea content. Rennet coagulation time, urea, protein and fat contents were determined using Berridge, photometric, formol titration and Gerber methods, respectively. Data were classified as follows; lactation stages: 1 (30 +/- 15, 60 +/- 15, 90 +/- 15 days): 2 (120 +/- 15, 150 +/- 15, 180 +/- 15): 3 (210 +/- 15, 240 +/- 15, 270 +/- 15); calving year: 1 (2004), 2 (2005); calving season: 1 (January-May), 2 (September and October); month of samples collection: 1 (June), 2 (September), 3 (December), 4 (March); lactation order: 1 and 2 : 1, 3 and 4: 2, 5 and 6: 3. Effects of environmental factors on each variable were investigated separately and analysed using analysis of variance. Production mount on all the characteristics; calving year and lactation stage on most of the characteristics; lactation order on fat and protein contents; unit and calving season on some of the characteristics were found to be effective significantly.

    Growth Traits of Anatolian and Anatolian x Italian Crossbred Buffalo Calves Under the Village Conditions
    (Int Buffalo Information Ctr, 2013) Sekerden, Ozel
    The study was carried out to compare growth performances of Anatolian and crossbred (Anatolian x Italian) buffalo calves (53 F-1, 66 Anatolian, 26 F(1)xAnatolian) raised at Ilikpinar Village of Kirikhan District of Hatay Province. Body measurements were determined in the period of 0-12 months of age. The effects of genotype, sex, birth year effects on each characteristic in each age were investigated using GLM variance analysis. The means of each characteristic in each age for each genotype were calculated. Duncan test was used in comparison of the averages of each characteristic SPSS programme was used in the statistical procedures. Genotype created significant variation in live weight at 1 and 6 months of ages respectively and on almost every body measurement almost in every age. Genotype* birth weight, genotype* sex and genotype* birth year* sex interactions were found statistically significant in the point of view of various characteristics in various ages. Factors had significant effects on various characteristics in various ages. It can be said that, F-1 growth was the most speedly and Anatolian buffaloes stayed behind of the other genotypes from the point of view of all the traits.
