    Cervical ripening is associated with M1 macrophages and inflammatory cytokines in mice and rats, but its mechanism in cattle is unclear. In this study, to elucidate some of the mechanisms of normal cervical maturation in cows, we examined the expressions of M1 macrophages and mRNA of interleukin (IL)-1α, 1β, 6, 8, and 10, as well as TNFα in cervical tissue and the mRNA expressions and protein concentrations of these cytokines in cervical mucus from late pregnancy to parturition. Forty-one Japanese Black cows were sampled at 200, 230, and 260 d of gestation and then at 7 d intervals until parturition to obtain cervical mucus and tissue samples. The collected tissues were fluorescently immunostained with anti-Iba-1 antibodies, and the macrophage infiltration was checked. Cervical mucus was mixed with PBS, the concentrations of the above cytokines in the supernatant after centrifugation were measured, and the concentration per protein weight was used as the measurement. Total RNA was extracted from the cervical tissue and mucus, and the mRNA expression of various cytokines was analyzed using real-time PCR. In cervical tissue, macrophages stained with anti-Iba-1 antibody were observed from five to six weeks before calving until the week of calving. There was also a trend toward a concurrent increase in the mRNA expression of inflammatory cytokines, especially IL-6, three weeks before calving (P < 0.05). In cervical mucus, the concentrations of IL-1α, IL-1β, IL-8, and TNFα increased (P < 0.05) zero to three weeks before calving compared to 12–14 weeks before calving. In addition, IL-1α mRNA increased three weeks before and during the week of parturition, and IL-8 mRNA increased three weeks before and two weeks after (P < 0.05). These results suggest that cervical ripening in cows begins five to six weeks before calving when macrophages infiltrating cervical tissue may produce large amounts of IL-6, inflammatory cells infiltrate cervical mucus, and IL-1α, IL-1β, IL-8, and TNFα levels in the mucus increase toward calving.

    Calf mortality severely affects productivity in the beef industry. The present study was conducted to assess the calf mortality risk (CMR) in Japanese Black calves and investigate potential associations between calf/cow information and the CMR. Records for calves born between April 2006 and March 2010 were extracted from an existing database, which included production data on commercial cow-calf operations in Miyazaki, Japan. The study group comprised 40,462 calves born to 15,600 cows on 908 farms. Because calves on the studied farms were weaned at approximately 4 months of age, the calf records were collected from birth to 120 days. The CMR was calculated as the number of dead calves divided by the number of surviving calves. Mixed-effect multivariable logistic regression modeling was used to determine potential associations between the CMR and the factors hypothesized to influence that risk. CMR analyses were performed separately for the following production stages: days 0–30, days 31–60, days 61–90 and days 91–120 after birth. Of the 40,462 calves, 1465 died during days 0–120 after birth, and the CMR was 3.6 %. Of the 1465 dead calves, 35.9 % died within 10 days after birth. During the 0–30-day period, the CMR was associated with dam parity, calving status, gestation length, sex, birth season and twin births (P < 0.05), but not with the number of inseminations to conception. Low parity, dystocia, gestation lengths < 280 days and > 301 days, male calves, calves born in autumn and winter and twin births yielded higher CMRs. Low dam parity also yielded higher CMRs during the 31–60-day, 61–90-day and 91–120-day periods (P < 0.05), but no other factors were associated with the CMR during these periods. Thus, various cow and calf factors were shown to be associated with CMRs in Japanese Black calves, and calves with these factors should be considered high-risk calves.

    Dystocia and stillbirths in cows pose a high risk of loss of both dams and fetuses, thereby resulting in high economic losses. One of the causes of these problems is birth canal abnormalities. Thus, to prevent these occurrences, it is necessary to understand the mechanisms underlying cervical ripening. Although physiological inflammatory responses and changes in collagen composition have been reported in humans and mice, related information is scarce for cows. We observed inflammatory changes and changes in the collagen composition in the cervix from late pregnancy to parturition to clarify some of the physiological changes associated with cervical ripening during normal calving in cows. Cervical mucus and tissue samples were collected from 41 Japanese Black cows at 200, 230, and 260 days of gestation and at 7-day intervals thereafter until parturition. The percentage of polymorphonuclear neutrophils (PMN%) in the mucus was calculated, and interleukin (IL)-8 concentration was determined by enzyme-linked immunosorbent assay. Blood samples were collected from the jugular vein, and leukocyte counts were determined. Picrosirius red-stained cervical tissue specimens were observed under a polarizing microscope, and the percentage of type I and type III collagen areas in the cervical tissue were calculated. The PMN% in cervical mucus was lowest at 200 days gestation (12–13 weeks before delivery), significantly increased 5 weeks before (21.7 ± 0.04), and was highest 1 week before calving (50.9 ± 0.04). IL-8 levels were increased at 295 days compared with those at 200 days of pregnancy (p < 0.05). No significant changes were observed in the white blood cell counts. The percentage of type I collagen in the cervical tissue reached a maximum (91.4 ± 0.02%) on day 200, significantly decreased after 274 days (3 weeks before calving), and continued to decrease thereafter until the week of parturition. There was no significant change in type III collagen levels. The results suggest that cervical ripening progresses when PMNs begin to infiltrate the cervix at around 260 days of gestation (5–4 weeks before parturition), IL-8, which increases at the end of pregnancy, mobilizes PMNs, and enhances inflammation, and that type I collagen changes are useful as an indicator of cervical ripening.

    This study aimed to clarify the relationship between the maternal pelvis and calf size in normal and dystocia groups (Experiment 1) and to establish a method to predict dystocia due to physical imbalance between foetus and maternal pelvis before calving based on the parameters found in Experiment 1 (Experiment 2). In Experiment 1, 26 pairs of dams and their offspring were tested immediately after calving, and various parameters of offspring size and maternal pelvis were measured in normal and dystocia cases. The longitudinal diameter of the maternal pelvis was smaller (p <.01), and ratios of the offspring's birth weight and the width of the hoof crown (hoof width; measured using callipers) to the longitudinal diameter of the maternal pelvis were larger (p <.01) in the dystocia group than those in the normal group. In Experiment 2, 37 cows were tested, and in addition to the measurement items of Experiment 1, the inner pelvic diameter and the foetal hoof width were measured via ultrasonography at 285 days of gestation. The ratio of the internal diameter of the maternal pelvis (longitudinal diameter, transverse diameter and area) to the foetal hoof width was compared and was greater (p <.01) in the dystocia group than in the normal group. In conclusion, the risk of dystocia can be estimated by the ratio of the foetal hoof width to the longitudinal diameter of the maternal pelvis before calving.

    その結果,修復群(FIU+)および未修復群(FIU+)の子宮外径は修復群(FIU-)および未修復群(FIU-)と比較してそれぞれ有意に大きく,修復群(FIU+)では修復群(FIU-)よりも有意に大きい内膜径を示した.PMN%は修復群(FIU-)と修復群(FIU+)で高値を示す個体が認められ,10%を超える個体の割合はそれぞれ23.8%(5/21),40.9%(9/22)であった.一方,未修復群(FIU-)と未修復群(FIU+)のPMN%はいずれも低値を示し,10%を超える個体は認められなかった.全頭における膣粘液スコア別のPMN%について,スコア4はスコア0,1,2および3に比べて有意(P<0.01)に高値を示した.膣粘液スコアやPMN%に対する,検査時の黄体の有無による影響は認められなかった.修復群と未修復群における膣粘液スコアならびにPMN%に有意差は認められなかった.

  • ストレスを減らし、日光浴としっかり栄養で強い牛を!

    エフエム宮崎  畜産王国みやざき!~元気森森で日本を元気に!!~  2024.12.15

     More details

    ゲストは宮崎大学農学部付属動物病院 病院長の大澤健司さんです。宮崎大学農学部獣医学科教授と日本繁殖生物学会理事長も兼任される大澤さんに牛の医療と繁殖についてお話を聞きました。終息したもしくは撲滅したと思っていた感染症が再流行したり、いままで日本では存在していなかった感染症が流行するなど、感染症との闘いに終わりが見えません。専門家大澤さんが農家さんにアドバイスするとしたら免疫力と抵抗性の高い「強い牛を作る」ことだそうです。ストレスを減らし、日光を浴び、しっかり栄養をとり、ワクチンや抗生物質は適正な使用を心がけること。人間と同じですね。繁殖についても日本人が開発した技術を紹介します。ほかにも、牛で技術を培った胚培養士の以外なお仕事もこっそり教えちゃいます。

    今回の「王国のホットタイム」は宮崎大学農学部付属動物病院 病院長の大澤健司先生による特別講座です。
    まずは「臨床試験」のやり方とn数の取り方についてです。私たちが自分で臨床試験をすることはありませんが、「なるほど」な決まりがあるそうです。さらに先生が注目する遠隔獣医療技術について紹介します。法整備含めて課題はありますが、必要になってくる技術だそうです。

    最後に今後の牛産業を担う若者に「技術のチカラで温暖化を食い止めながら、サステナブルな牛産業を続けていくために、世界を見て新しい視点と柔軟な思考を身に付けてほしい」と熱いメッセージを送ります。学生に戻ったつもりでぜひご覧ください。
