Various management practices may cause the occurrence of reproductive failure indicated by repeat breeding in beef cattle. This study aimed to estimate the prevalence and the risk factors of repeat breeding in beef cattle in Sleman Regency, Indonesia.
Observational and cross-sectional studies were used to determine the prevalence and the risk factors of repeat breeding. Sampling was conducted using a multistage cluster design. The sample size was determined using a sampling formula (n=4 PQ/L2). Questionnaire and interview data were evaluated descriptively. Chi-square analysis and odds ratio (OR) test were conducted to determine the association and association strength with a confidence level of 95%. Univariate, bivariate, and multivariate analysis through multivariate logistic regression test was done using Statistical Package for the Social Sciences, version 21.0 software.
The results indicated that the prevalence of repeat breeding in beef cattle in the Sleman Regency was 30.4%. Multivariate analysis indicated that risk factors that significantly affected the repeat breeding were breeding experience (p=0.000; OR=3.378), knowledge of estrus cycle (p=0.000; OR=5.263), feed type (p=0.001; OR=6.061), feeding frequency (p=0.003; OR=2.77), shed hygiene (p=0.33; OR=2,381), and drainage system (p=0.000; OR=4,484).
Various husbandry management significantly influence the incidence of repeat breeding in beef cattle in Sleman Regency with the type of feed, which was the highest risk factor. Hay should not be used as the main feed source since it might increase the incidence of repeat breeding. However, the other environmental factors such as season and presence of infection or parasite also need to be investigated further.
各种管理措施可能导致肉牛出现繁殖失败,表现为屡配不孕。本研究旨在估计印度尼西亚斯莱曼摄政区肉牛屡配不孕的患病率及风险因素。
采用观察性和横断面研究来确定屡配不孕的患病率及风险因素。抽样采用多阶段整群设计。样本量通过抽样公式(n = 4PQ/L²)确定。对问卷和访谈数据进行描述性评估。进行卡方分析和优势比(OR)检验,以确定关联及关联强度,置信水平为95%。使用社会科学统计软件包21.0版软件,通过多变量逻辑回归检验进行单变量、双变量和多变量分析。
结果表明,斯莱曼摄政区肉牛屡配不孕的患病率为30.4%。多变量分析表明,对屡配不孕有显著影响的风险因素包括繁殖经验(p = 0.000;OR = 3.378)、发情周期知识(p = 0.000;OR = 5.263)、饲料类型(p = 0.001;OR = 6.061)、饲喂频率(p = 0.003;OR = 2.77)、牛舍卫生(p = 0.33;OR = 2.381)和排水系统(p = 0.000;OR = 4.484)。
各种饲养管理措施对斯莱曼摄政区肉牛屡配不孕的发生率有显著影响,其中饲料类型是最高风险因素。不应将干草用作主要饲料来源,因为这可能会增加屡配不孕的发生率。然而,其他环境因素,如季节以及感染或寄生虫的存在,也需要进一步研究。
