Avaliação da qualidade do colostro e transferência de imunidade passiva em bezerros da raça Holandesa
(2019-01-11) Costa, Luana Paes da; Bispo, Safira Valença; http://lattes.cnpq.br/2541084650429493; http://lattes.cnpq.br/4760336574562419
In addition to the basic care we must have with newborns, there is no doubt that the supply of colostrum is among the most important factors, conferring nutrients and essential substances against pathogens. The bovine placenta type does not allow the transfer of antibodies from the mother to the fetus. This compromises their development, increasing morbidity and mortality rates, making it essential to administer a quality colostrum soon after the first hours of life, because in this initial phase, the capacity of absorption by the newborns is greater. The objective of this study was to evaluate the quality of colostrum and the transfer of passive immunity to newborn bovines of the Dutch breed. The work was carried out at the Agronomic Institute of Pernambuco (IPA), São Bento do Una experimental station, where nine calves were born between october and december 2018, with a mean weight of 34 kg. Soluble solids present in the colostrum samples were analyzed by the BRIX refractometry method after the first postpartum milking. The concentration of total proteins in the plasma samples was also analyzed with the serum protein refractometer, in the period between 24 and 48 h after birth. The results demonstrated good to high quality colostrum, resulting in successful passive immunity transfer. However, the amount of colostrum supplied shortly after birth was the main determinant, so that the higher the ingested volume the higher the concentration of proteins in the blood and the better the passive immunity transfer.
Criptosporidiose em ruminantes e sua importância em saúde pública
(2018) Macedo, Darlan Rodrigues; Cajueiro, Jobson Filipe de Paula; http://lattes.cnpq.br/1163226949462180; http://lattes.cnpq.br/8208793638612108
Cryptosporidiosis is an important disease in cattle breeding, calves up to 30 days of age being the most susceptible category. The etiological agents are protozoans of the genus Cryptosporidium, which complete their cycle in respiratory, urinary and gastrointestinal epithelial cells of birds, reptiles and mammals including man. The route of infection is fecal-oral. The infection occurs after ingestion of food and water contaminated with sporulated oocysts, which contain sporozoites inside. Production animals mainly calves are the main sources of environmental contamination and therefore an important risk factor for other animals and man. The clinical manifestation of the disease is due to the lesions in the gastrointestinal tract that occur through the rupture of enterocytes with persistent and watery diarrhea. Diarrhea is the main cause of death in calves up to 30 days old, being one of the main agents Criptosporidium sp. Cryptosporidiosis is a zoonosis with a worldwide distribution, with children between the ages of 1 and 5 years, adults being transplanted and immunocompromised individuals, high risk groups, where this enteroparasite can cause severe enteritis and may lead to death. However, immunocompetent adults may present with diarrheal episodes. Diarrhea is the main cause of death in calves up to 30 days old, being one of the main agents Criptosporidium sp. Cryptosporidiosis is a zoonosis with a worldwide distribution, being children from 1 to 5 years of age, transplanted adults and immunocompromised individuals, high risk groups, in which this enteroparasite can cause serious enteritis and may lead to death. However, immunocompetent adults may present with diarrheal episodes. Risk factors include contact with sick animals or carriers, together with lack of adequate hygiene habits and basic sanitation. Prophylaxis consists of vaccination of pregnant cows, the use of some drugs that help prevent diarrhea, as well as reduce the amount of oocysts removed in the faeces, correct administration of colostrum and, in cases of sick animals, supportive therapy for the reestablishment of the hydroeletrilic balance and basic acid. Other factors such as parasite resistance in the environment and disinfectants, lack of knowledge by health professionals about epidemiology and diagnostic methods, and ineffective treatment make it a major public health problem in the world.
Hérnia umbilical em bezerro: relato de caso
(2019-02-01) Machado, Evandro dos Anjos; Baptista Filho, Luiz Carlos Fontes; http://lattes.cnpq.br/2627279097684607; http://lattes.cnpq.br/9498329135340190
Cattle breeding is one of the most critical stages in cattle breeding since problems occurring during this period can lead to many losses, including high mortality, costs of veterinary services, and delay in development, discarding of future breeding stock and breeding delays. Among the affections that affect the calves, we can highlight the occurrence of the umbilical hernia, which despite being a disease well studied, is still quite neglected by the producers. Umbilical hernia is a non-infectious omphalopathic disease that can be acquired or congenital, which affects mainly young bovines, causing imperceptible damages to the rural producers. It has relatively simple treatment, especially when diagnosed early. With this, the objective of this work is to report the occurrence of an umbilical hernia in a mixed-blooded Holstein heifer attended at the Clínica de Bovinos de Garanhuns. The animal was aged between 10 and 11 months, the owner complained that it had increased volume in the ventral region of the abdomen since its birth, with progressive increase since then. Upon physical examination, the patient presented tachycardia (108bpm), elevated body temperature (39.4°C), increased volume in the umbilical region with soft contents, reducible without difficulties, thus diagnosed the umbilical hernia. Herniorrhaphy was thus indicated as a therapeutic protocol. The animal presented satisfactory recovery, with removal of the points eight days after surgery, receiving discharge. The early diagnosis is of great importance so that it can favor a suitable treatment for the animals that happen to be affected by umbilical hernias. Consideration should be given to existing techniques and to consider which will be the most appropriate for each patient, since this provides a good recovery of the animal; this choice is the responsibility of the veterinarian. The heifer of the present report, despite age, responded well to the therapeutic protocol, possibly due to the size of the hernia ring and adequate choice of the correction method, through herniorrhaphy.

Durante o período de 27 de junho a 13 de setembro de 2022 na Fazenda Bodopitá no município de Caturité-PB foi realizado o estágio supervisionado obrigatório -ESO para conclusão do curso de bacharelado em zootecnia, por meio do acompanhamento das atividades no sistema produtivo de bovinocultura leiteira, desde os afazeres no bezerreiro incluindo o recebimento dos animais seu desenvolvimento durante as fases de cria e recria até o manejo alimentar de todos os animais, conservação de forragem por meio do processo de ensilagem, manejo sanitário envolvendo a desinfecção das instalações a vermifugação e vacinação dos animais, além do manejo reprodutivo com protocolo de sincronização de cio e inseminação artificial, manejo das vacas no período de ordenha e testes de qualidade do leite, e todo esse processo foi avaliado e supervisionado pelo zootecnista que atualmente está na propriedade, participando do programa de agroresidência da Universidade Federal Rural de Pernambuco UFRPE Lucas Santos da Silva e orientado pela Professora da Universidade Federal Rural de Pernambuco Unidade Acadêmica de Serra talhada, Dra. Ana Maria Duarte Cabral. Durante o período de estágio foi possível ainda realizar algumas atividades fora dos afazeres da fazenda, como o acompanhamento do recebimento e análise do leite recebido no laticínio próximo a fazenda Bodopitá, visita a propriedades acompanhadas pelo projeto de residência agropecuária da UFRPE e participação na exposição de caprinos e ovinos da cidade de Queimadas -PB. Desta forma através do ESO foi possível o aprimoramento dos conhecimentos adquiridos em sala de aula tendo sua aplicação na prática do dia a dia de uma propriedade.
