Abstract in Portuguese
Temos presenciado um crescimento expressivo da ovinocultura de corte nos últimos anos. Algumas doenças de grande importância econômica tem sido motivo de estudos, não apenas pelo impacto econômico que representam, mas também para a saúde do animal e do homem. Com a crescente preocupação com resíduos de medicamentos pesticidas nos produtos de origem animal, perda da qualidade do leite e conseqüente baixo ganho de peso dos borregos de corte, os sistemas orgânicos de produção vem ganhando espaço. Sabe-se que a mastite subclínica é uma das responsáveis pelo baixo rendimento de carcaça na ovinocultura de corte. Neste experimento, optou-se por realizar tratamento com medicamento homeopático (Phytolaca decandra) das ovelhas com tetos diagnosticados com CMT 2+ e 3+, sem sinais de mastite clínica. Dois lotes de ovelhas com mastite subclínica foram usados. Um lote controle que recebeu placebo e o lote tratado que recebeu remédio homeopático duas vezes ao dia junto ao concentrado a partir da quarta semana do parto (de lactação). Foram colhidas duas amostras de cada tetos com mastite subclínica no início do experimento (30 dias do parto) e a cada 15 dias até o desmame quando os borregos tinham aproximadamente 60 - 65 dias de vida. Das amostras colhidas, uma seguiu para identificação do agente microbiológico e outra para a contagem de células somáticas (CCS). Ao final do estudo não houve diferença estatisticamente significativa entre as CCSs da secreção láctea quando comparadas antes e depois do tratamento homeopático no mesmo grupo, bem como quando comparou-se ambos os grupos (tratados e placebo). Porém observou- se que o grupo tratados apresentou redução significativa (P<0,05) nos isolados das amostras com Staphylococcus spp. e aumento significativo de amostras sem crescimento bacterianos (negativas) e ganho de peso estatisticamente significante (P<0,05) quando comparado ao grupo placebo.

Abstract in English
We have seen an expressive growth of lamb production in the last years. Some diseases of economic importance have been studied not just by its economic impact but also for the animal and human health. With worry about pesticides and drugs' remaining (left over) in animal origin products, the loss of milk quality and consequent lamb's low gain weight, the organic production systems are growing up. It's known that subclinical mastitis is one of the most dangerous and one of those held responsible for the decrease of weight-gain in lamb breeders. In this experiment, it was chosen to use homeopathic medication for ewes whose half udder was diagnosed 2+ and 3+ on CMT (California Mastite Test) without signs of clínical mastitis. Two groups of subclinical mastitis ewes were used. The first one received placebo BID (no treated group) and the second one received homeopathic medication (Phytolaca decandra) BID (treated group) in concentrated food since the 4Th week of lambing. Two milk samples were taken from each injured gland 30 days after lambing and each 15 days until 60-65 days after lambing, when the lambs were weaning. One of the milk samples went to microbiological identification and the other one to SCC (somatic cell count). By the end of the research, neither was it found statistical difference between samples of milk before and after homeopathic treatment from the three milk sampling in the same group nor did it happens when the groups treated and placebo were compared. However, it was observed that the treated group showed significant decrease (P<0,05) samples with Staphylococcus spp. and significant increase of samples without bacteriological growth as well as gain of weight statistically significant (P<0,05) when compared with the placebo groups.
