SİYAH ALACA IRKI İNEKLERDE LAKTASYON SAYISININ VE ÜREME DURUMUNUN PİK SÜT VERİMİ VE BAZI DÖL VERİM ÖZELLİKLERİNE ETKİSİ

Year 2013, Volume: 53 Issue: 1, 17 - 27, 01.06.2013

Abstract

Bu çalışmada, Konya ili çevresinde özel bir çiftlikte yetiştirilen Siyah Alaca ineklerin pik süt verimi ve bazı döl verim özelliklerine laktasyon sayısının ve üreme durumunun etkisini belirlemek amaçlanmıştır. Laktasyon sayısı, 1 (n=105), 2 (n=97), 3 (n=42), 4 (n=72) ve 5+ (n=24) olarak belirlenmiştir. Çalışmada pik süt verimi (PSV), buzağılama aralığı (BA), gebelik başına tohumlama sayısı (GBTS) ve servis periyodu uzunluğu (SP) incelenmiştir. Laktasyon sayısı (1, 2, 3, 4, 5+) en küçük kareler ortalamaları sırasıyla; PSV (24.11±1.89, 32.90±1.33, 33.28±2.57, 29.47±1.58, 35.72±1.62 kg), BA (528.77±29.45, 438.37±20.78, 417.18±40.07, 406.57±24.63, 424.46±25.27 gün), GBTS (2.56±0.46, 1.92±0.33, 2.03±0.63, 1.76±0.39, 2.26±0.40) ve SP (137.63±13.00, 96.60±9.17, 92.94±17.69, 85.46±10.87, 77.81±11.16 gün) olarak belirlenmiştir. Üreme durumu (abort, açık, gebe, tohumlanmış) en küçük kareler ortalamaları sırasıyla; PSV (30.58±1.38, 32.13±1.88, 29.60±0.40, 34.59±0.79 kg), BA (510.66±22.18, 403.47±30.38, 418.41±6.50, 390.64±12.81 gün), GBTS (3.11±0.35, 1.23±0.48, 2.02±0.10, 1.69±0.20) ve SP (90.94±9.89, 115.87±13.54, 87.34±2.90, 84.78±5.71 gün) olarak tespit edilmiştir. Laktasyon sayısının, PSV (P<0.001), BA (P<0.05) ve SP (P<0.01), üreme durumunun
PSV (P<0.001), BA (P<0.001) ve GBTS (P<0.01) üzerinde önemli etkisi olmuştur. PSV ve BA (-0.12; P<0.05), PSV ve GBTS (-0.19; P<0.001), BA ve GBTS (0.71; P<0.001), BA ve SP (0.29; P<0.001) ve GBTS ve SP (- 0.14; P<0.01) arasında önemli fenotipik korelasyonlar bulunmuştur. Sonuç olarak bu çiftlikte yetiştirilen Siyah
Alaca ineklerde bazı döl verim özelliklerinin iyileştirilmesi için daha iyi bakım, besleme ve sürü idaresinin uygulanması gerekmektedir.

Effect of Parity and Reproductive Status on Peak Milk Yield and Some Reproductive Traits of Holstein Cows

Year 2013, Volume: 53 Issue: 1, 17 - 27, 01.06.2013

Abstract

The purpose of this study was to investigate the effect of parity and reproductive status on peak milk yield and some reproductive traits of Holstein cows reared in a private dairy farm of Konya province. Parities were 1 (n=105), 2 (n=97), 3 (n=42), 4 (n=72) and 5+ (n=24). Investigated characters were peak milk yield (PMY), calving interval (CI), number of artificial insemination per pregnancy (AIN) and service period (SP). Parity least squares means (1, 2, 3, 4, 5+), respectively, were; PMY (24.11±1.89, 32.90±1.33, 33.28±2.57, 29.47±1.58, 35.72±1.62 kg), BA (528.77±29.45, 438.37±20.78, 417.18±40.07, 406.57±24.63, 424.46±25.27 days), AIN (2.56±0.46, 1.92±0.33, 2.03±0.63, 1.76±0.39, 2.26±0.40) and SP (137.63±13.00, 96.60±9.17, 92.94±17.69, 85.46±10.87, 77.81±11.16 days). Reproductive status least squares means (aborted, open, pregnant, inseminated), respectively, were; PMY (30.58±1.38, 32.13±1.88, 29.60±0.40, 34.59±0.79 kg), CI (510.66±22.18, 403.47±30.38, 418.41±6.50, 390.64±12.81days), AIN (3.11±0.35, 1.23±0.48, 2.02±0.10, 1.69±0.20) and SP (90.94±9.89, 115.87±13.54, 87.34±2.90, 84.78±5.71 days). Parity significantly affected PMY (P<0.001), CI (P<0.05) and SP (P<0.01). Reproductive status significantly affected PMY (P<0.001), CI (P<0.001) and AIN (P<0.01) The Significant phenotypic correlations were found between PMY and CI (-0.12; P<0.05), PMY and AIN (-0.19; P<0.001), CI and AIN (0.71; P<0.001), CI and SP (0.29; P<0.001) and AIN and SP (-0.14; P<0.01). As as result, better feeding and herd management practices should be provided to improve the reproductive performance of Holstein cows in this dairy farm
