Compare The Reproductive Performance And Success Rates Between Ai And Natural Breeding In Large Animals To Determine The Advantages And Disadvantages Of Each Method
Keywords:Artificial insemination, Calf mortality, Neonatal mortality, Reproductive performance
Background: Artificial insemination (AI) and natural breeding are two commonly employed methods in large animal reproduction.
Objectives: This captivating study delves into the realm of large animal reproduction, comparing the outcomes of AI and natural breeding to unravel the advantages and disadvantages of each method.
Methods: Native cow breeds of Pakistan were meticulously evaluated, with 56 healthy and sexually mature animals participating in the investigation. The reproductive parameters scrutinized encompassed conception rate, pregnancy rate, time to conception, calving rate, birth weight, and neonatal mortality rate. The data was meticulously analyzed using chi-square tests and descriptive statistics, revealing intriguing insights into the reproductive landscape.
Results: The study found that both AI and natural breeding yielded comparable results in terms of conception rate (AI: 75.0% vs. natural breeding: 64.2%), pregnancy rate (AI: 71.4% vs. natural breeding: 53.5%), time to conception (AI: 12-24 hours vs. natural breeding: 18-24 hours), calving rate (AI: 60.7% vs. natural breeding: 71.4%), birth weight (AI: 34 kg vs. natural breeding: 37 kg), and neonatal mortality rate (AI: 10.7% vs. natural breeding: 7.14%).
Conclusion: These findings suggested that both methods exhibited similar effectiveness in achieving conception, establishing pregnancy, ensuring successful calving, and influencing birth weight and neonatal mortality rates.
