Sustentabilidade no sistema de produção de leite em pequenas propriedades rurais em Bragança – Pará

A atividade leiteira tem um importante papel na sustentabilidade das unidades de base familiar, tanto no autoconsumo como na geração de renda, no entanto é necessário que seja economicamente viável para evitar a saída do homem do campo. Os objetivos deste trabalho foram fazer um acompanhamento técnico em propriedades leiteiras com intuito de maximizar a produção de leite a pasto, melhorar a qualidade do leite através da adoção de Boas Práticas de Produção e tornar os sistemas de produção de leite sustentável. Foi aplicado um questionário com intuito de obter informações sobre infraestrutura da unidade produtora, manejo dos animais e traçar o perfil dos produtores. Além disso, as alunas vivenciaram a rotina da propriedade desde a ordenha das vacas até a comercialização do leite. Como resultados alcançados têm-se a capacitação dos produtores rurais em adquirir animais com aptidão leiteira, manejo nutricional e sanitário adequado e adoção de boas práticas de produção de leite. Um trabalho sobre a sustentabilidade do sistema de produção leiteiro no município de Bragança-PA é bastante relevante, devido à falta de tecnologia e aplicação de manejos impróprios, resultando em produtos lácteos com baixo valor comercial e sem qualidade

Luxação de patela lateral, congênita, bilateral em cão: Relato de caso

Foi diagnosticado um caso de luxação patelar lateral bilateral congênita em um cão, macho, da raça Poodle, dois anos de idade, que inicialmente apresentava grau 3, evoluindo ao grau 4 no membro esquerdo após cirurgias para correção. A luxação patelar lateral é pouco frequente e afeta principalmente cães de raças grandes e gigantes, sendo condição rara em cães de raças pequena e miniatura

Background: Elective ovariohysterectomy (OH) is minimally invasive, but when performed incorrectly, it can lead to postsurgical complications, such as stump pyometra, ovarian remnant syndrome and foci of adhesion generated by tissue reactions to threads and materials used in vessel hemostasis. The formation of adhesions and successive surgeries predisposes patients to other diseases, such as ureteral obstruction and hydronephrosis. Thus, we reported a case of hydronephrosis in a bitch submitted to conventional OH, followed by ovariectomy (OV) due to ovarian remnant syndrome and consequent intraperitoneal adhesions caused by successive surgical interventions. Case: A 11-year-old mixed breed medium size bitch with a history of stump pyometra and ovarian remnant syndrome (SOR) was treated at the Veterinary Hospital-HV of UFPA after 2 previous surgeries. It had been spayed using conventional OH and underwent ovariectomy OV approximately 4 years ago, as it showed signs of estrus after the first surgery, characterizing SOR. On physical examination, its abdomen was distended especially in the left hemiabdomen, with no palpable pain. Ultrasonography showed a cavity in the topographic area of the left kidney, with anechoic content, thin walls, and defined contour. There were nonvascularized tubular structures, suggesting hydroureter and severe hydronephrosis. Exploratory celiotomy was performed, showing the intense presence of abdominal adhesions, followed by an incision in the abdominal midline from the xiphoid process in a caudal direction to the pubis, thereby showing the left kidney. After vesical drainage of 900 mL of renal filtrate, atrophy of the renal parenchyma and preservation of the renal capsule was considered, resulting in its complete resection, followed by the synthesis of the abdominal wall. In the postoperative period, the patient was properly monitored and obtained a satisfactory outcome manifested by a complete recovery. After vesical drainage of 900 mL of renal filtrate, atrophy of the renal parenchyma and preservation of the renal capsule only was considered, resulting in its complete resection, followed by the synthesis of the abdominal wall. In the postoperative period, the patient was properly monitored and obtained a satisfactory outcome manifested by a complete recovery. After vesical drainage of 900 mL of renal filtrate, renal parenchymal atrophy and preservation of the renal capsule only was adopted. Discussion: The choice of the conventional OH technique, followed by the failure to perform, favored the formation of adhesions only diagnosed late. Less invasive alternatives achieved less long-term damage. Excessive intracavitary manipulation and reaction to the nylon suture thread favored the development of these adhesions, and consequently, unilateral obstruction of the left ureter, hydroureter, hypertrophy, and destruction of the renal parenchyma, led the patient to undergo a third surgery, namely, unilateral nephrectomy. In this case, no changes were observed in serum levels, leaving only a subtle abdominal enlargement with hydronephrosis installed silently. There was no possibility of carrying out initial surgical planning, as the affected kidney, making unilateral nephrectomy necessary. Currently, the patient has normal renal function in the contralateral organ, with no clinical or laboratory changes because the affected kidney was not functional, making unilateral nephrectomy necessary.
