Objective: This study presents a comprehensive investigation into the impact of gender on various aspects of growth performance in Turkish native geese, specifically in the Kars region. Materials and Methods: A total of 62 goslings, comprising 25 males and 37 females, were monitored over 12 weeks. The study focused on growth performance, live weight gain, survival rates, and growth pattern modeling. Results: In the course of our investigation, the acquired findings have brought to light a discernible gender effect during specific measurement periods, wherein a notable influence of sex on growth performance was observed. Males consistently manifested markedly higher live weights in comparison to females during weigh-ins. This gender-related disparity was statistically significant on both the hatching day (p<0.01) and throughout the period spanning weeks 6 to 12 (p<0.05), underscoring substantial differences in growth performance between the two genders. Remarkably, male geese displayed significantly higher daily live weight gains during weeks 5 to 6 (p<0.01). Linear regression analyses emphasized gender's influence on live weight gain, with female geese demonstrating an R² value of 0.9044 (p<0.001) and male geese showing an R² value of 0.8912 (p<0.001). Gompertz growth models unveiled distinctive growth patterns. In females, an R² value of 0.9300 highlighted their growth trajectory, while males exhibited an R² value of 0.9194. Survival rates after a 12-week period were 81.7% for females and 80.0% for males. Conclusion: In conclusion, this meticulous exploration of the impact of gender on growth trajectories underscores the significant role it plays. [ABSTRACT FROM AUTHOR] |
