Diagnosis and therapy of retained fetal membranes, puerperal metritis and clinical endometritis in cattle: Results of the Online-survey among Swiss practitioners. II. Puerperal metritis and clinical endometritis

The aim of the study was to obtain the diagnostic and therapeutic approach among Swiss practitioners in cows with puerperal metritis and clinical endometritis (part 2). All members of the Association for ruminant health were contacted per email via the newsletter. The survey was completed by 128 veterinarians, partially responded by 140 veterinarians. The following main symptoms of puerperal metritis were stated by the practitioners: purulent vaginal discharge, fever and reduced appetite. A vaginal and rectal examination was performed to diagnose the disease. Usually, an intrauterine treatment with tetracycline or cefapirin was done. Parenteral administration of tetracycline or penicillin was often combined with PGF(2α), NSAIDS or cortisone. Clinical endometritis was also diagnosed by vaginal and rectal examination and the main symptom indicated was purulent vaginal discharge. The therapy consisted of the administration of PGF(2α), uterine infusions predominantly with cefapirin, and rarely with parenteral administration of antibiotics. Further diagnostic tools were not used and normally cows were not rechecked. The success of the therapy of puerperal metritis and clinical endometritis was judged to be satisfactory to excellent.

Diagnosis and therapy of retained fetal membranes, puerperal metritis and clinical endometritis in cattle: Results of the Online-survey among Swiss practitioners. I Retained fetal membranes

The aim of this study was to obtain the diagnostic and therapeutic approach among Swiss practitioners in cows with retained fetal membranes (RFM) (part 1). All members of the Association for ruminant health were contacted per email via the newsletter. The survey was completed by 128 veterinarians, partially responded by 140 veterinarians. The manual removal of the fetal membranes is practiced by 129 of the responding veterinarians. Cows with/without fever are treated usually with intrauterine antibiotics. Cows with RFM with/without fever are most commonly treated parenterally with tetracycline or penicillin. The use of cephalosporins and quinolones in cows with fever is more common than in cows without fever. With the present results of the survey veterinarians should critically question the supposed benefits of the manual removal of the placenta and the use of antibiotics in cows with RFM.

[Evaluation of risk factors for Mastitis-Metritis-Agalactia in pig farms in Switzerland].

Mastitis-Metritis-Agalactia (MMA), also known as postpartum dysgalactia syndrome (PPDS) is the most important disease complex in sows after birth. The present study compared 30 MMA problem herds (over 12% of farrowing sows affected) with 30 control farms (less than 10% of farrowing sows affected) to identify risk factors and treatment incidence. Important risk factors identified were in gilts the integration into the herd after the first farrowing, in gestating sows firm fecal consistency as well as in lactating sows soiled troughs, a low flow rate (<2 liters per minute) in drinking nipples and a high prevalence of lameness. The treatment incidence was also significantly different between the two groups. The MMA prevalence could be reduced through optimization of husbandry, feeding and management, which could essentially diminish the use of antibiotics.

Le profil de virulence d' Escherichia coli intra-utérin permettrait de prédire la métrite postpartum chez la vache laitière

Les objectifs de cette étude ont été de : (1) déterminer s’il existe une association entre la présence intra-utérine d'Escherichia coli dans la 1 ère semaine postpartum et le développement de la métrite postpartum, (2) déterminer s’il y a une association entre les gènes de virulence d'E. coli et la métrite postpartum, et (3) d'évaluer si les analyses bactériologiques (bactéries et gènes de virulence d'E. coli) pourraient prédire la métrite postpartum chez la vache laitière. Des écouvillons utérins ont été prélevés dans la première semaine postpartum sur 486 vaches de race Holstein et soumis au laboratoire pour détection de E. coli. Les gènes de virulence d'E. coli ont été identifiés par la technique d'hybridation des sondes radioactives. Un total de 252 vaches (52%) ont été positives à E. coli et 67 vaches positives à la métrite postpartum (13,7%). Les vaches positives à E. coli intra-utérin dès la première semaine postpartum avaient un risque 2,6 fois plus élevé de développer la métrite postpartum que les vaches sans E. coli. La plupart des E. coli possédaient un ou plusieurs gènes des E. coli d'origine extra-intestinale (ExPEC) dont fimH (89%), HlyE (87%) et iss (70%). Parmi les autres gènes ExPEC, on a retrouvé sitA (23%), fepC (20%) hra1 (20%) malX (14%) tsh (11%) et bien d'autres. Les gènes de virulence kpsMTII et hra1 ont été associés à la métrite postpartum avec un rapport de cote de 4,3 chacun. La présence d'E. coli dans l'utérus avait une valeur prédictive positive de 18% tandis que la présence des gènes kpsMTII et hra1 avait une valeur prédictive positive de 36% et 31% respectivement. La détection de certains gènes de virulence d'E. coli dans les prélèvements utérins pourrait renseigner sur le risque de développement de la métrite postpartum chez la vache laitière. Les études ultérieures pourraient tester encore plus de gènes et viser à développer des tests de dépistage simple, facilement et rapidement applicable à la ferme.

Involução uterina em um rebanho Gir leiteiro segundo o período pós-parto e o número de parições

Durante três anos, vacas Gir leiteiro da Fazenda Experimental da EPAMIG, em Uberaba-MG, foram examinadas, pela palpação retal, para verificação da involução uterina. em 111 parições de 104 vacas, a involução dos cornos uterinos teve duração média de 29,7± 9,6 dias e, na maioria das vezes, a involução da porção cervical demorou mais do que 43 dias. O tempo de involução foi mais longo em vacas com maior número de partos. Na primeira semana, o útero permaneceu na cavidade abdominal (95,0%), na segunda teve início o retorno do órgão à pelve (8,2%), na terceira aconteceram os primeiros casos de involução completa dos cornos uterinos (20,6%) e na sexta semana, a maior parte das vacas apresentavam involução completa (82,9%). Foram constatados seis casos de permanência do útero em involução na cavidade abdominal e oito casos de localização pélvico/abdominal na quinta semana após o parto, detectados somente em vacas pluríparas. Observaram-se 19 casos de retrocesso na seqüência natural das fases de involução. O retrocesso do útero para a cavidade abdominal só ocorreu em vacas com problemas sanitários. em sete vacas com metrite, verificou-se prolongamento do tempo médio de involução dos cornos uterinos e aumento do diâmetro cervical em relação às demais vacas do rebanho.

Inducing ovulation early postpartum influences uterine health and fertility in dairy cows

The objective of the current study was to evaluate the effect of GnRH early postpartum on induction of ovulation, uterine health, and fertility in dairy cows. Holstein cows without a corpus luteum (CL) at 17 +/- 3 DIM were assigned randomly to receive i.m. GnRH (n = 245) at 17 +/- 3 and 20 +/- 3 DIM or remain as controls (n = 245). Ovaries were scanned by ultrasonography twice weekly totaling 4 examinations. Ovulation was characterized by the appearance of a CL >= 20 mm at any ultrasound or CL <20 mm in 2 consecutive examinations. Clinical and cytological endometritis were diagnosed at 35 DIM. Compared with control, GnRH increased ovulation up to 3.5 d after the last treatment (78.7 vs. 45.0%) and did not affect the prevalence of clinical endometritis (23.9 vs. 18.6%) or cytological endometritis (30.9 vs. 32.8%). Prevalence of clinical endometritis increased in cows that had calving problems (32.6 vs. 15.9%) and metritis (40.6 vs. 15.8%). Metritis increased prevalence of cytological endometritis (50.7 vs. 23.5%). Treatment with GnRH did not affect pregnancy per artificial insemination at 32 (37.6 vs. 38.6%) or 74 d after artificial insemination (35.0 vs. 31.5%), but reduced pregnancy loss (6.8 vs. 18.1%). No overall effect of GnRH treatment on hazard of pregnancy was observed; however, an interaction between GnRH treatment and ovulation showed that GnRH-treated cows that ovulated had increased hazard of pregnancy by 300 DIM compared with GnRH-treated and control cows that did not ovulate (hazard ratio = 2.0 and 1.3, respectively), but similar to control cows that ovulated (hazard ratio = 1.1). Gonadotropin-releasing hormone early postpartiim induced ovulation without affecting uterine health, but failed to improve pregnancy per artificial insemination or time to pregnancy, although it reduced pregnancy loss.

Atualidades no tratamento da laminite em equinos

Laminitis is still a major cause of lameness in horses, causing damage to many interested in it. It has been long studied, but there are several points that are not yet fully understood. Doubts about its pathogenesis end up extending at the treatments. Just as there are several theories that attempt to explain the mechanisms of its development, also appear treatments that are sometimes contradictory and inconsistent. Mostly times, laminitis is a consequence of another disease process that occurs systemically in the body. Among them are the main grain overload and processes that cause the animal to the table of endotoxemia, strangled colic, metritis with retained placenta and pleuropneumonia. The proposed treatments include the use of anti-inflammatory drugs, cryotherapy, use of vasodilators and correction of Starling forces, and other measures to support the frog. The stall should be bedded deeply with sand or other material that provides support to the frog

Sanidade Uterina Pós Parto: Aspectos Imunológicos e Terapêuticos

Function of the uterus is often compromised in cattle by bacterial contamination of the uterine lumen after parturition. Pathogenic bacteria often persist, causing uterine disease, a major cause of infertility in cattle. Knowledge of the immunological aspects of the uterus involved in maintaining reproductive healthiness is fundamental to the study of uterine infections that affect the uterus postpartum. Polymorphonuclear leukocytes have an important role because they are the first line of defense against colonization of bacteria in utero (Hammon and Goff, 2006). The establishment of uterine infection depends in parts of endocrine environment, particularly progesterone, which suppresses the immune system (Lewis, 2003). In the puerperium may occur uterine disorders, such as retained placenta, puerperal metritis, clinical and subclinical endometritis and pyometra, this review was proposed a study of the immunology involved in uterine health and a better understanding of uterine disorders, using the model of Sheldon et al. al, (2006) for classification of diseases, and a study of best treatment options and discussion about its functionality, because a lot of controversy among authors about choosing a treatment and another and between treated and untreated
