O edema pulmonar cardiogênico é de extrema importância devido a sua urgência e relevância dentro da clinica médica de pequenos animais. Consiste no acúmulo de líquido extravascular dentro do parênquima pulmonar, sendo resultado de uma falha circulatória que acomete o lado esquerdo do coração. O diagnóstico é baseado nos sinais clínicos como dispneia, tosse, alteração da ausculta pulmonar e exames de imagens. O tratamento tem como objetivo melhorar a congestão, restabelecer a hemodinâmica, estabilizar o paciente, melhorar a qualidade de vida e aumentar a sobrevida do mesmo. O Pimobendan é uma das medicações mais utilizadas no tratamento das afecções de origem cardiológica, incluindo a insuficiência cardíaca congestiva, devido ao seu duplo mecanismo de ação como um inotrópico positivo e um vasodilador.

[Effect of gynecological screening on rates of conception and gestation total of Nellore cows submitted to three protocols for fixed-time artificial insemination (TAI).] Efeito da triagem ginecologica sobre as taxas de concepcao e gestacao total de vacas Nelore submetidas a tres protocolos de inseminacao artificial em tempo fixo (IATF).

Email: [email protected] The aim of this study was to assess the rates of total conception and gestation of Nellore cows total, commercial herd in the region of the coastal plains of the state of RJ, subjected to three hormonal protocols for synchronization of ovulation with screening of females for inclusion in the TAI program. Two hundred and six lactating females with multiple calvings history were used (60 to 100 days after parturition), divided into four groups: I - Ovsynch, n = 55, II - Ovsynch + progesterone, n = 55, III - EB. + P4 + eCG, n = 48, IV - EB. + P4 + eCG, n = 48. All females were exposed to bulls of Simmental breed, from 24 hours to pass after TAI. The conception rates and pregnancy rates were 45.5% overall (25:55) and 81.8% (45:55) for group I, 61.8% (34:55) and 87.3% (48 : 55) for group II, 62.5% (30:48) and 87.5% (42:48) for group III, 60.4% (29:48) and 83.3% (40:48) for group IV, respectively. The results, after analysis by the chi- -square showed no significant difference (p> 0.05) among protocols, as compared to the conception and pregnancy rates after transfer with total bulls. Thus, the use of gynecological screening for insertion of cows in the TAI program of the respective property, allows adaptation of the protocols for ovarian function, providing good pregnancy rates independent of the protocol used.

Protocol I - "OvSynch" (OV) in which received 0.025 mg of buserelin acetate in D0; 0.15 mg d-cloprostenol on D7; 0.025 mg buserelin acetate D9; It is inseminated at fixed time in D10. Protocol II - "OvSynch" + progesterone (OP4) and III Protocol - "OvSynch" + LH + P4 (OP4LH). Protocols II and III followed the same dosages of "OvSynch" associated with the introduction of intravaginal device containing 1g first use of progesterone in D0 and D7 in withdrawal. In Protocol III, LH replaced buserelin acetate in ovulation induction (D9; 25m...

Incidence of these is lessened in bilateral versus unilateral twin pregnancy. This study was undertaken to assess use of follicular ablation by aspiration to create bilateral twin pregnancies in females with genetic potential for ~3.5 ovulations per cycle (Trio allele carriers). In Experiment 1, carriers (n = 30) and non-carriers (n = 10) were synchronized for ovulation and timed artificial insemination (TAI). Follicles (> 5 mm) in excess of one per ovary were aspirated ~16h preceding TAI. Follicle count for females with follicles on only one ovary was reduced to two. Blood was sampled 2 weeks post-TAI to assess progesterone (P4) concentrations; fetal count was determined by ultrasound 6 weeks post-TAI. P4 concentration post-TAI was significantly (P < 0.001) associated with both genotype and subsequent pregnancy status (pregnant non-carriers, 7.06 ± 0.68 ng/mL...

Blood samples were collected from 40 dairy cows in their reproductive phase from the cranial superficial epigastric vein. The blood samples were tested using the Indirect Fluorescence Antibody Test (IFAT) to detect anti-N.caninum antibodies. The serological results were used to verify whether there was any association with the manifestation of reproductive disorders based on data from the records of reproductive history from 2017 to 2018 as well as the clinical observations of the herd throughout this study. The Fisher exact test was used to verify the existence of an association between the serology and reproductive disorders, adopting a 95% confidence level. The serological results showed a 27.5% seroprevalence in the herd for N. caninum, however, after statistical analysis, no associati...
