In this study, we determined the occurrence of reproductive diseases in does on 1373 visited farms in Spain and Portugal, between 1994 and 2019. The retrospective information obtained was entered in a database classified as follows: apparent infertility (≤70% pregnancy rate), abortions (≥2% of serviced does), high fetal death risk at parturition (≥10%) or dystocia, amongst others. Infertility was the reason for 181 visits. The median of prevalence of apparent infertility in these cases was 35% (minimum to maximum: 25–90%) and the mean, 37.4%. We performed a prospective study to determine risk factors at the individual and farm level, with a second database corresponding to 2014–2019. We carried out pregnancy checks, assessed sanitary status and body condition, and recorded the age of 17,297 rebred lactating does on 142 farms. The median size of the farms was 800 does, and the examined cohorts, 350 does. Predisposing risk factors for infertility were observed: e.g., mastitis had an effect. During the 5-year study, we made a third database with the results from 190,508 does palpated by producers in a subset of 134 farms. In this case, the median of the prevalence of apparent infertility was 14.5% (minimum to maximum: 4.1–50%), which could be considered baseline occurrence when monitoring the theriogenology of rabbit doe farms. Reproductive rhythm was an enabling risk factor: does serviced ≤25 d postpartum were less fertile than at ≥32 d. We made a database with the body condition score (BCS) on a linear scale from 1 (emaciated) to 9 (obese). The pregnancy rate (PR) of underweight and borderline does (4/9) was 73.1%. The PR of overweight and borderline does (6/9) was 82.6% and those classified with a mean BCS (5/9): PR = 79.3%. We may infer that the optimum BCS for reproduction is 6/9, rather than 5/9. Some changes in female rabbit health and husbandry to improve reproductive performance and welfare are highlighted.

养殖兔子的生殖系统疾病

在这项研究中，我们确定了1994年至2019年之间西班牙和葡萄牙的1373个探视农场中的生殖疾病的发生。所获得的回顾性信息输入数据库中，分类如下：表观不育（≤70％妊娠率），流产（≥人工服务的2％），高分娩时胎儿死亡风险（≥10％）或难产等。不孕是181次就诊的原因。在这些情况下，不育症的患病率中位数为35％（最低至最高：25–90％），平均值为37.4％。我们进行了一项前瞻性研究，以确定个人和农场一级的风险因素，并使用了与2014–2019年相对应的第二个数据库。我们进行了孕期检查，评估了卫生状况和身体状况，并记录了142个农场的17297头泌乳后代的年龄。农场的中位数为800英担，接受调查的队列为350英担。观察到易患不育的危险因素：例如，乳腺炎起作用。在为期5年的研究中，我们建立了第三个数据库，其中包含134,508个农场中子集的生产者的190,508份果蝇的结果。在这种情况下，表观不育患病率的中位数为14.5％（最小至最大：4.1–50％），在监测兔子母猪场的造山学时，可以将其视为基线发生。生殖节律是一个可能的危险因素：产后≤25 d的服务是否比≥32 d的生育能力差。我们建立了一个身体状况评分（BCS）线性范围从1（消瘦）到9（肥胖）的数据库。体重过轻和边缘性（4/9）的怀孕率（PR）为73.1％。超重和临界线的PR（6/9）为82。6％的人群和平均BCS（5/9）的人群：PR = 79.3％。我们可以推断出，用于复制的最佳BCS是6/9，而不是5/9。强调了雌性兔子健康和饲养方面的一些变化，以改善生殖性能和福利。
