Abstract:
New postpartum strategies have been developed in dairy cows to ameliorate uterine health and reproductive performance, especially the first service conception rates. This study aimed to assess the effect of intrauterine therapy with ozone (IUTO) in early postpartum on subclinical endometritis prevalence and reproductive parameters in dairy cows under commercial farm conditions. For this purpose, eighty clinically healthy cows with a body condition score between 3.0 and 3.5, from four dairy farms, were randomly allocated into two groups: ozone therapy group (OG, n?=?40), which were subjected to IUTO, and control group (CG, n?=?40). Content of uterine polymorphonuclear (PMN) leukocytes and subclinical endometritis (SE) percentage were assessed at 35 days after calving by uterine cytology. A second cytology was performed 72 h after IUTO. Reproductive parameters such as interval calving to first service (IFS), number of services per conception (nSC), interval calving to conception (ICC) and first service conception rate (FSCR) were analysed. The second endometrial cytology demonstrated that IUTO reduced (P?0.01) both PMN (3.7?±?1.4 vs. 7.6?±?1.1%) and SE (5.0 vs. 50.0%) percentages compared with CG. Likewise, after ozone treatment, both nSC (2.1?±?0.3 vs. 3.1?±?0.2; P?0.01) and ICC (126.2?±?9.7 vs. 149.0?±?9.0; P?=?0.0672) decreased, and FSCR increased (50.0 vs. 16.2%; P?0.01) compared with CG. In conclusion, intrauterine ozone therapy applied at 35 days after calving reduced subclinical endometritis prevalence and improved reproductive performance in postpartum dairy cows managed in a pasture-based system.

ABSTRACT.
Amorimia septentrionalis is an important sodium monofluoroacetate (MFA) containing plant that causes sudden death in ruminants in northeastern Brazil. MFA degrading bacteria are being used in the prevention against poisoning by this plant. The aim of this study was to evaluate if goats which had per os received MFA degrading bacteria remained resistant when exposed to natural poisoning by A. septentrionalis. Eighteen goats were randomly distributed into three groups: the goats of Group 1 previously received, during 40 days, a solution containing the bacteria Ralstonia sp. and Burkholderia sp., those goats in the Group 2 received the bacteria Paenibacillus sp. and Cupriavidus sp. and goats from Group 3 did not receive any bacteria. After the administration period, during 60 days, the animals of all groups were released to graze on a one hectare paddock, with significant amount of A. septentrionalis. They were observed daily for the spontaneous consumption of A. septentrionalis leaves and the occurrence of clinical signs of poisoning or sudden death. Goats from all groups consumed significant amounts of A. septentrionalis during the experimental period. Goats that did not receive MFA-degrading bacteria (Group 3) became sick and died from the 25th to the 27th day of the experiment, whereas the goats of the groups that received MFA-degrading bacteria showed only clinical sings when A. septentrionalis regrowth after the 55th day of the experiment. The days elapsed from field observation to death of Group 3 goats (25.5±0.9 days) were significantly lower (p<0.05) than Group 1 (58.6±1.3 days) and Group 2 (57.8±1.5 days). Thus, it can be concluded that administration of MFA degrading bacteria increases the resistance to natural poisoning by A. septentrionalis.

RESUMO.
Amorimia septentrionalis que contém monofluoroacetato de sódio (MFA) é responsável pela ocorrência de mortes súbitas em ruminantes no nordeste do Brasil. Bactérias degradadoras desse composto estão sendo utilizadas na prevenção contra a intoxicação por essa planta. O objetivo deste estudo foi avaliar se caprinos que receberam, via oral, bactérias degradadoras de MFA permaneciam resistentes quando expostos a intoxicação natural por A. septentrionalis. Dezoito caprinos foram divididos em três grupos, os caprinos do Grupo 1 receberam anteriormente, durante 40 dias, uma solução contendo as bactérias Ralstonia sp. e Burkholderia sp., os do Grupo 2 receberam, também por 40 dias as bactérias Paenibacillus sp. e Cupriavidus sp. e os do Grupo 3 não receberam nenhuma bactéria. Após o período de administração, durante 60 dias, os animais de todos os grupos foram soltos para pastar em um piquete de um hectare, que apresentava uma quantidade significativa da planta. Diariamente eles foram observados quanto ao consumo espontâneo das folhas de A. septentrionalis e quanto à presença de sinais clínicos de intoxicação ou morte. Os caprinos de todos os grupos consumiram quantidades significantes da planta durante o período experimental. Os caprinos que não receberam as bactérias degradantes de MFA (Grupo 3) adoeceram e morreram entre o 25º e o 27º dia de experimento, enquanto que os que receberam as bactérias degradantes de MFA (Grupo 1 e 2) só apresentaram sinais clínicos no 55º dia de experimento, o que coincidiu com a rebrota da planta. Os dias transcorridos desde a observação a campo até a morte dos caprinos do Grupo 3 (25,5±0,9 dias) foram significativamente menores (p<0,05) que os do Grupo 1 (58,6±1,3 dias) e do Grupo 2 (57,8±1,5 dias). Com isso pode-se concluir que a administração de bactérias degradadoras de MFA aumenta à resistência a intoxicação natural por A. septentrionalis. MenosABSTRACT.
