Item Distúrbios locomotores associados a desordens nutricionais em galinhas de fundo de quintal - Relato de caso(2023-09-04) Silva, João Paulo Gomes da; Mendonça, Fábio de Souza; http://lattes.cnpq.br/1976344298387988; http://lattes.cnpq.br/2210109777543280The Mandatory Supervised Internship was carried out in two different locations, with the first part performed during the period from June 1st to 30th (2023), at the Animal Diagnostic Laboratory (LDA-UFRPE), totaling 176 hours. The second part, held between July 3rd and August 14th (2023), took place at the Veterinary Pathology Laboratory (LPV) and the Conservation Medicine Laboratory (LAMCON), both at the Federal University of Paraíba (UFPB), Campus II, totaling 248 hours. The internships were based on diagnosing diseases in domestic, wild, and exotic animals, emphasizing the pathology of birds and wild animals. During this period, necropsies, cytology, and biopsies were carried out, with important necropsies of wild animals at risk of extinction or domestic animals with zoonotic diseases being carried out, and highlights the relevance of the role of pathology in the conservation of species and its value in public health. Metabolic and nutritional diseases represent an important portion of illnesses in poultry, constituting a considerable cause of early slaughter in commercial farms. Vitamin and mineral deficiencies are associated with locomotor disorders in poultry, which can cause syndromes that impact the mobility of these animals. Chickens without adequate nutrition often manifest syndromes known as “leg weakness” and “twisted leg” syndrome, characteristic of deficiencies in Niacin (B3), Choline (B8), Manganese, Calcium or Zinc, mainly. This study aimed to describe the clinical and anatomopathological findings of these two conditions in backyard poultry. Six chickens, of different ages and from the Agreste region of Pernambuco, were clinically examined due to the manifestation of progressive locomotor problems. One bird was sent for necropsy, the organs were fixed in 10% buffered formalin and routinely processed for histopathology. Clinically, the animals exhibited imbalance, difficulty standing, falls, and difficulty getting up. One of the birds presented a slight deviation of one of the legs, with slightly thickened hocks bilaterally and unilateral subluxation of the gastrocnemius tendon on the affected leg. The bones offered no resistance to cutting. Diseases of the locomotor system have different etiological agents, and it is necessary to analyze the macroscopic and microscopic aspects and the animal history to make a diagnosis. The occurrence of outbreaks on the property and the lesions found reflect a possible deficiency, unique or synergistic, of essential dietary components such as B vitamins, Calcium, Zinc, or Manganese, which are responsible for the integrity of connective and bone tissues, and whose lack promotes the emergence of chondrodystrophic lesions.Item Avaliação do comportamento e do perfil bioquímico de abelhas africanizadas (Apis mellifera Lepeletier) expostas ao herbicida glifosato por ingestão(2019-12-02) Costa, Hadja Lorena Rangel Uchôa Cavalcanti de Menezes; Gomes, Renata Valéria Regis de Sousa; http://lattes.cnpq.br/8551019809231664; http://lattes.cnpq.br/5029931499676592The increasing use of pesticides in production systems as a way to eliminate pests or weeds has impacted the survival of pollinating insects of these crops. Among these, bees have been the most harmed, and there have been reports of alarming declines in the number of colonies around the world. With the increasing use of glyphosate-based herbicides, there is a need to assess the impacts of this pesticide on bees, as bees are responsible for pollinating 73% of the world’s cultivated vegetables and their disappearance can cause serious damage. the economy. The objective of this research was to evaluate the behavioral and biochemical alterations resulting from the ingestion exposure of Africanized bees to glyphosate active ingredient. The research was conducted at the Animal Genetics and Bee Breeding Laboratory of the Department of Zootechnics of the Federal Rural University of Pernambuco (DZ / UFRPE), and was divided into two stages: 1 - Preliminary bioassay with exposure time of 6 hours; and 2 - Bioassay with 24 hours of exposure. The experiments were performed in triplicate, totaling the use of 90 worker bees in both stages. During the experiments, the bees were kept in a climate-controlled environment with an average temperature of 23.9 ± 0.8 ° C and 50% humidity, distributed in three treatments, forming the following groups: T1 (control) - 1: 1 60 sucrose and 60 mL distilled water, T2: 960 μL glyphosate added to 120 mL syrup (1: 1 60 g sucrose and 60 mL distilled water), and T3: 1,920 μL glyphosate added to 120 mL syrup (1: 1 60 g sucrose and 60 ml distilled water). The commercial product used was Roundup®, using the minimum dose indicated by the manufacturer. Bees’ behavior was observed every 30 minutes. The biochemical analyzes performed were related to lipid, total sugar, glycogen and protein content. Behavioral alterations are observed after 2h of exposure, showing as desorientation and lethargy behavior as controls T2 and T3 bees, differing statistically from T1 control. The first bee deaths occur at T2 and T3 within the first 6 hours of the experiment. In the biochemical analysis used, glycogen and sugars values are reduced, totaling the effects of glyphosate inclusion (T2 and T3), differing from the use of treatment control. The protein and lipid values did not present statistically significant difference between the three treated. It was concluded that an ingestion of glyphosate caused behavioral changes and biochemical parameters of Africanized bees.
