摘  要：
选取预产期相近的围产期荷斯坦牛150头,随机分为3组,每组50头,试验1组、2组、3组分别饲喂50g/(头·d)的过瘤胃氯化胆碱产品A、B、C(诺瑞康)。试验期为产前15d～产后30d,其中预试期15d,正试期30d。结果表明:①在29℃和相对湿度58%的条件下,产品A、B和诺瑞康放置6d的吸潮率分别为4.14%、4.35%、1.47%,其中以诺瑞康的吸潮率最低;②产品A、B和诺瑞康的8h溶出度分别为10.18%、79.02%、5.51%,其中以诺瑞康的溶出度最低;③围产期奶牛饲喂产品A、B和诺瑞康后,试验牛体况不合格率增长幅度分别为12%、22%、6%,以诺瑞康组增长幅度最小;④试验2组临床型、亚临床型酮病发生率高于试验前,1、3组均呈下降趋势,均以试验3组(诺瑞康组)降低幅度最大。由此可知,在本试验条件下,综合考虑产品吸潮率、溶出度和各组酮病发病率指标,以诺瑞康的使用效果最好。

摘  要：
This experiment was conducted to determine the different rumen-protected choline chloride on moisture absorption rate, dissolution rate and the effect on perinatal incidence of ketosis in Holstein cows. A total of 150 perinatal Holstein cows were divided into 3 groups, and each group had 50 cows. The product A was fed on 50 g/(d·head) in group 1, and product B was fed on 50 g/(d·head) in group 2, and Nuoruikang was fed on 50 g/(d·head) in group 3. The trial period was from 15 days before delivery to 30 days after delivery. The pretest lasted for 15 d, and the test lasted for 30 d. The results showed as follows: 1) Under the condition of 29℃ and 58% humidity, the 6 th day moisture absorption rates of product A, B and Nuoruikang was 4.14%, 4.35% and 1.47%, respectively, especially the Nuoruikang group was the lowest. 2) The 8 h dissolution rate of products A, B and Nuoruikang was 10.18%, 79.02% and 5.51%, respectively, especially the Nuoruikang group was the lowest. 3) After perinatal feeding of products A, B and Nuoruikang, the rate of abnormal body condition of the cows increased by 12%, 22%, and 6%, with the least increase in the Nuoruikang group. 4) After perinatal feeding of products A, B and Nuoruikang, the incidence of clinical ketosis decreased by 6%,-25%, 8%, and the incidence of subclinical ketosis decreased by 4%,-10%, 8%, respectively, with the largest decrease in the Nuoruikang group. Based on the moisture absorption rate, dissolution rate and ketosis incidence index, it can be seen that Nuoruikang was most effective.
