RESUMEN
Gastrointestinal parasites are a significant challenge in sheep farming, and periparturient ewes are one of the most susceptible categories in sheep flocks. This study aimed to verify whether the injection of B vitamins at the acupuncture point governing vessel 14 (GV14) can influence the parasitic load or host-parasite interaction in naturally infected ewes during the peripartum period. Four weeks before parturition, 25 ewes were divided into five treatment groups: (1) Dose Control: 0.2 mL of B complex via IM; (2) Drug Control: 2 mL Complex B via IM; (3) Acupoint Control: 0.2 mL of Water at GV14 point; (4) Control; (5) Test group: 0.2 mL of B complex at the GV14 point. Treatments were performed at weeks -3, -1, 2, 4, and 6 about the parturition time. Fecal samples to estimate the parasitic load by fecal egg counts (FEC) and total blood samples for hemogram examination were performed seven days after the treatment, coinciding with weeks -2, 3, 5, and 7 about the parturition time. The number of peripheral eosinophils was higher in group 3 than in group 1 (p <0.05). Although groups 3 and 5 had lower mean values of FEC and higher hematological values at the time of weaning, these differences were not statistically significant (p> 0.05) according to the F test. However, all animals in groups 3 and 5 maintained low parasitism levels until the end of the experiment. Further studies should be performed with larger sample sizes and minor changes to the experimental protocol to elucidate the role of GV14 acupoint stimulation in the host-parasite relationship.(AU)
A parasitose gastrointestinal é o principal desafio sanitário para a criação de ovinos a pasto, e as ovelhas no periparto são uma das categorias mais susceptíveis a esta infeção no rebanho. O objetivo deste trabalho foi verificar se a injeção de vitaminas do complexo B no acuponto Vaso Governador 14 (VG14) poderia influenciar a carga parasitária ou modular a interação hospedeiro-parasito em ovelhas naturalmente infectadas no período de periparto. Quatro semanas antes da data prevista para o parto, 25 ovelhas foram divididas em cinco grupos de tratamento (1) Controle da dose: 0,2 mL de vitaminas do complexo B via IM; (2) Controle do fármaco: 2mL complexo B via IM; (3) Controle do Ponto: 0,2 mL de água destilada no ponto VG14; (4) Controle sem tratamento; (5) Grupo teste: 0,2 mL de complexo B no pontoVG14. Estes tratamentos foram realizados nas semanas -3; -1; 2; 4 e 6 em relação à data do parto. Amostras de fezes para contagem de ovos por grama de fezes (OPG), assim como amostras de sangue para realizar o hemograma, foram obtidas dos animais sete dias após os tratamentos, coincidindo com as semanas -2, 3, 5 e 7 do parto. O número de eosinófilos periféricos foi superior no grupo 3 se comparado ao grupo 1 (p <0,05). Os animais dos grupos 3 e 5 tiveram menores valores de OPG e maior hematócrito, mas estas diferenças não foram consideradas significativas pelo teste F (p> 0,05). No entanto, todas as ovelhas dos grupos 3 e 5 se mantiveram com níveis baixos de parasitismo durante todo o experimento. Sugere-se que novos estudos sejam realizados com algumas modificações deste protocolo a fim de aprofundar o conhecimento do potencial imunomodulador do acuponto VG14.(AU)

Background: The growth of exotic pet medicine is leading to fast developments in clinical investigations on birds. Acupuncture, specifically pharmacopuncture, offers safe chemical restraint options. Objectives: To investigate pharmacopuncture at acupoint GV20 in blue-fronted Amazon parrots (Amazona aestiva) using ketamine and midazolam. Methods: Sixteen healthy birds were distributed into four groups (C: intramuscular control; 1/2 C: 1/2 dose intramuscular control; 1/2 GV20: 1/2 dose at acupoint GV20; 1/5 GV20: 1/5 dose at acupoint GV20). Degree of sedation, latency, recuperation time, heart and respiratory rate, and body temperature were measured. Quantitative data were analyzed by a Student's t-test. Results: The C, 1/2 C, and 1/2 GV20 groups showed the same degree of sedation. The 1/2 GV20 group showed longer latency times (6 ± 2.1) than the 1/2 C (2.5 ± 0.5) group. Sedation time did not differ between the C (28 ± 9.8), 1/2 C (30.5 ± 8.6), and 1/2 GV20 (41 ± 22.24) groups. The 1/2 GV20 group recuperated faster (13.7 ± 3.7) than the C group (64.2 ± 3.5). The C and 1/2 C groups showed tremors and slow and unstable recovery. Two animals in the C group showed mild hypothermia (38°C). Conclusion: The use of 1/2 GV20 was effective and safe to sedate blue-fronted Amazon parrots without side effects, providing easy, stable, and fast recovery. The use of 1/5 GV20 had a shorter sedation time. These findings show that the combination of acupuncture and drugs provides new possibilities for efficient anesthetic protocols with fewer side effects in birds.
