Item Relatório de Estágio Supervisionado Obrigatório (ESO) realizado na Empresa Brasileira de Pesquisa Agropecuária - EMBRAPA Gado de Leite, Juiz de Fora e no Laboratório de Biotécnicas Aplicadas à Reprodução do Departamento de Medicina Veterinária da Universidade Federal Rural de Pernambuco: efeito da adição de nanoemulsão à base de óleo essencial rico em limoneno ao diluente de refrigeração de sêmen caprino(2024-02-15) Nottar, Luiz Henrique Todescatt; Batista, André Mariano; http://lattes.cnpq.br/5615914349535394; http://lattes.cnpq.br/3747311074315408The present study aims to report the activities carried out in compliance with the discipline 08525 - Mandatory Supervised Internship (MSI), part of the Bachelor's Degree in Veterinary Medicine, conducted between October 2, 2023, and November 28, 2023, at the Brazilian Agricultural Research Corporation (Embrapa), in the Dairy Cattle unit in the municipality of Juiz de Fora - MG, and between January 2 and January 19, 2024, at the Laboratory of Biotechniques Applied to Reproduction (LBR) of the Department of Veterinary Medicine (DMV) of the Federal Rural University of Pernambuco (UFRPE). The activities carried out provided in-depth training in in vitro embryo production (IVP) techniques for research purposes, including follicular aspiration of ovaries from abattoirs, in vitro maturation (IVM), in vitro fertilization (IVF), and in vitro embryo culture (IVC). Activities in the field of molecular biology involving DNA extraction and amplification through the Polymerase Chain Reaction (PCR) technique were also performed. In the second chapter of this study, a research was conducted to evaluate the effect of adding nanoemulsion based on limonene-rich essential oil extracted from wild orange peel (NELS) to the semen extender of goat breeders. Seminal samples from five Saanen breed goats were used for the research. Each seminal pool was diluted in Tris-egg yolk supplemented with NELS at concentrations of 1.25, 2.5, and 5% at a concentration of 200 × 106 sperm/mL. The samples were placed in Eppendorf tubes (1.5 mL) and stored in refrigeration boxes (botuflex®) for cooling curve determination up to 5 ºC, and after 2 hours, they were transferred to the refrigerator, also at a controlled temperature of 5 ºC. For each analysis, part of each sample was aliquoted and transferred to other Eppendorf tubes (1.5 mL) in a dry bath at 37 ºC and subsequently evaluated in the Computer-Assisted Sperm Analysis System (CASA) for sperm kinetics, and in epifluorescence microscopy for Mitochondrial Membrane Potential (MMP), Plasma Membrane Integrity (PMI), and Acrosomal Membrane Integrity (AMI). The addition of wild orange nanoemulsion to the Tris-egg yolk extender was not able to improve sperm motility and kinetic parameters, besides significantly reducing MMP after 24 hours of refrigeration.Item Acompanhamento e controle zootécnico do sistema de produção de pequenos ruminantes (caprinos e ovinos), do CODAI/UFRPE, localizado na região da Zona da Mata Norte, no município de São Lourenço da Mata - PE(2021-12-07) Brito, Admilson Ribeiro Toscano de; Freitas, João Antônio Gomes de; http://lattes.cnpq.br/1765326853404114; http://lattes.cnpq.br/7228033819346383The Obligatory Supervised Internship (ESO) was held at College Agricole Dom Agostinho Ikas of UFRPE, Campus-Tiúma, in the Animal Science Area, in the Nucleus de Caprinovinocultura, located in the forest Mata Norte region, in the district of Tiúma, municipality of San Lourenço of the Mata, Pernambuco, under the supervision of teacher Dr. João Antônio Gomes de Freitas and supervision of teacher Drª. Elisa Alves Vilar, with a total workload of 420 hours, in the period from 08/30/2021 to 11/16/2021. Zootechnical Monitoring and Control of the Goats and Sheep Production System were carried out, involving management of facilities; food management; reproductive management; productive management; sanitary management and disposal management. This work aimed to report the main activities related to the experiences developed during the referred internship, in the goat and sheep production nucleus of CODAI-UFRPE, in the routine of raising goats and sheep. The production nucleus, mentioned above, has a fixed squad of 22 animals; being 10 goats and 10 sheep (parents); 01 goat and 01 ram (breeders), in addition to the offspring, calving, which occur during the breeding routine. The goats are predominantly of the Anglo-Nubiana breed, while the sheep come from the Santa Ines breed. The intensive production system, with an emphasis on animal welfare, is the method adopted by the production nucleus. The installations consist of suspended bays with slatted floors. Nutritional and food management is carried out in a balanced way with elephant grass pasture (Pennisetum purpureum) and supplemented with protein and mineral concentrate. The main diseases observed and treated during this period were some bacterial diseases such as caseous lymphadenitis, food poisoning, epidermatitis and parasitic diseases such as worms. Discards are carried out following the guidelines for the genetic and productive improvement of the herd. During this period the animals showed an average weekly weight gain ranging from 250g to 350g per animal (50g/day).Item Relatório de Estágio Supervisionado Obrigatório(2021-12-12) Gomes, Evenn Katharynny Souza; Carvalho, Francisco Fernando Ramos de; http://lattes.cnpq.br/8552194153767195; http://lattes.cnpq.br/9947057920380953Item Balanço e eficiência de utilização de compostos nitrogenados em pequenos ruminantes alimentados com resíduo da indústria de doces/sucos em substituição ao milho(2021-12-03) Carone, Guilherme Morais; Véras, Antonia Sherlânea Chaves; http://lattes.cnpq.br/0074248045711399; http://lattes.cnpq.br/8358713370948321Goats and sheep breeding are extremely important activities for Brazil’s Northeastern region, because it is where most of these animal are. Being important not only for maintaining the rural population, but also being their main source of income. The nitrogen balance is the difference between the amount of nitrogen ingested and excreted via feces and urine. The evaluation of the nitrogen utilization is an important information to base the discussion about nutritional requirements for maintenance and production. The experimental design was a double latin square 4 x 4, each one composed by one species. The experiment lasted for 88 days (four periods of 22 days each), being each of them composed by 14 days of adaption to the diet and eight days of data collect. For this experiment there were used four male goats and four male sheep, all of them were castrated and had a rumen fistula. Their average initial weight was 70,1 kg ± 0,51 e 63,5 kg ± 1,08, for sheep and goats, respectively. The animals were fed twice a day in form of complete ration at 8 a.m. and 4 p.m., adjusted daily in function of the animal’s intake with a margin of 10 and 15% of leftovers. The samples of diets and leftovers were pre-dried in a forced ventilation oven at a temperature of 55 ± 5 ºC, for 72 hours; subsequently, they were ground in a 1 mm sieve strainer, for analysis regarding the dry matter and nitrogen contents. Variables were evaluated using analysis of variance and regression using the SAS PROC MIXED. All diets had a positive nitrogen balance, which indicates that the replacement of corn by RID did not significantly influence nitrogen digestion and the diets met the N requirements. It is noted that there was a significant difference (P < 0.05) in N intake and the amount of N in feces between species, being higher in sheep. The concentration of N-Ureic in blood plasma was influenced (P < 0.05) by the treatment, with a decreasing linear effect with the replacement of corn by the mixture of RID + FGM.Item Relatório de Estágio Supervisionado Obrigatório(2022-05-24) Souza, Gleidson Passos de; Souza, Andreia Fernandes de; http://lattes.cnpq.br/6354486109796073; http://lattes.cnpq.br/1891794335885463Item Aplicação das Boas Práticas Agropecuárias (BPA) na obtenção higiênica do leite de cabra por agricultores familiares do município de Paranatama, PE(Universidade Federal Rural de Pernambuco (SEDE); Unidade Acadêmica de Garanhuns, 2011) Brandespim, Daniel FrigugliettiO projeto tem por objetivo principal caracterizar o perfil dos caprinocultores de base familiar no município de Paranatama - PE, observando a adoção de boas práticas agropecuárias na ordenha, assim como sugerir práticas que contribuam com a melhoria da qualidade do processo produtivo, além de relacionar o nível de adoção de práticas higiênicas em ordenha com o perfil socioeconômico dos produtores de leite caprino de base familiar, orientar os produtores familiares sobre os procedimentos corretos no manejo higiênico-sanitário durante o processo de ordenha, transporte e armazenamento do leite caprino, identificar animais que apresentam mastite e orientar os produtores sobre o manejo correto com estes animais, bem como métodos de prevenção e controle; e também caracterizar o perfil zootécnico do rebanho, as práticas de manejo adotadas, principalmente sanitárias, reprodutivas e nutricionais.

The study was carried out in the goat sector, at the Department of Animal Science, at the Universidade Federal Rural de Pernambuco. A total of 45 kids were born, 18 males and 27 females, from 27 Saanen females. The number of kids (two and three) per birth was considered. On the second day of life, the animals were separated from the mothers and introduced into the artificial feeding system. The animals were weighed at birth, on the 10th, 45th and 60th days, on a digital scale. Analyzes of variance and the comparison of means by the Tukey test at 5%. Influence (P <0.05) of the number of kids per birth on birth weight, weight at 10, 45 and 60 days of life, mean weight gain and total weight gain of the animals were verified. There was an effect (P <0.05) of brood sex on birth weight and weight at 10, 45 and 60 days. It is concluded that the number of animals born per birth and sex influence the birth weight and the weight gain of the animals up to 60 days in Saanen animals submitted to artificial feeding.Item Relatório do Estágio Supervisionado Obrigatório (ESO), realizado no Laboratório de Andrologia e Ambulatório de Grandes Animais do Departamento de Medicina Veterinária da Universidade Federal Rural de Pernambuco(2018-08-31) Lima, Carlos André Ferreira; Bartolomeu, Cláudio Coutinho; http://lattes.cnpq.br/7619056086707716; http://lattes.cnpq.br/5611281478872633The Mandatory Supervised Internship (ESO) was conducted under the guidance of Prof. Dr. Cláudio Coutinho Bartolomeu.
