Saanen Ve Bornova Keçilerinde Oğlak Veriminin Üretkenliği ve Etkinliği

Abstract

This study was carried out to determine total kid productivity and total efficiency in Saanen and Bornova goats. Gestation productivity and gestation efficiency for Saanen and Bornova goats were 591 kg and 454 kg; 10.19 kg and 8.74 kg respectively. The effect of genotype on gestation productivity and gestation efficiency for Saanen and Bornova were found significant (P<0.05). Total kid productivity and total efficiency for Saanen and Bornova goats were 4337.39 kg and 3163.72 kg; 29.11 kg and 28.71 kg respectively.

The Effect of Some Environmental Factors on Growth Performance and Reproductive Traits in Saanen Goats

“…However the knowledge about pregnancy rate of Saanen is limited in the literature; the reported pregnancy rates were 90.04% and 76.00-82.50% in studies performed by Bolacali and Kucuk (2012) and Sen and Onder (2016) respectively. The infertility and abortion rates were found 2.40-18.30% and 9.73-13.16% in Saanen goats (Taskin et al, 2003;Ceyhan and Karadag., 2009;Ulutas et al, 2010;Bolacali and Kucuk., 2012;Ince, 2010;Akar, 2013). Multiple births are common in Saanen dairy goats (Jia and Wei, 2016;Kyssa et al, 2014).…”

“…Survival rate is the most important trait influencing the income in goat breeding (Afzal et al, 2004;McManus et al, 2008). The survival rate of Saanen kids was defined as 89.60% to 98.43% in previous studies (Taskin et al, 2003;Ceyhan and Karadag., 2009;Ulutas et al, 2010;. The NKP parameter was identified as 1.40 -1.85 (Taskin et al, 2003;Ceyhan and Karadag., 2009;Ulutas et al, 2010;Bolacali and Kucuk., 2012;Mellado et al, 2008); the NKM was 1.20-2.03 (Taskin et al, 2003;Ceyhan and Karadag., 2009;Ulutas et al, 2010;Bolacali and Kucuk., 2012;Sen at al., 2016) on an average.…”

While the significant impact of age on all reproductive parameters was emphasized by Bolacali and Kucuk.…”

“…In addition, these researchers reported the significant effects of year on abortion, single kidding, twining, NKP and NKM. On the other hand the effects of year and age on survival rate were just scrutinized by Taskin et al (2003) and the significant effects on survival rate were reported by them. All about these traits investigated in previous studies located on a wide scale, hence the clarification of the values is significant.…”

Особине Плодности И Млечности Санске Козе У Прве Три Лактације

“…Према томе, утврђене вредности у нашим истраживањима за плодност санске козе од 161,61% (табела 1) се налазе у оквирима очекиваних вредности за санску расу и у складу су са литературним подацима (Taskin et al, 2003;Gönцü et al, 2005 На основу изложених резултата (табела 2) просечна дужина лактације је била 244 дана, и утврђено је да су козе у III лактацији имале најдужи лактациони период од 249 дана, а да је најкраћа лактација од 241 дан утврђена код коза у I лактацији.…”
