Avaliou-se o efeito da substituição parcial do milho por sorgo granífero na dieta de suínos castrados sobre as características de desempenho, carcaça e avaliação econômica. Foram utilizados 27 machos híbridos, oriundos de linhagem comercial, com 19,66 ± 2,92kg de peso inicial, distribuídos em três tratamentos com porcentagens crescentes de sorgo granífero - 0%, 25% e 50% - em substituição ao milho, em um delineamento inteiramente casualizado. Foram avaliados: ganho diário de peso, consumo diário de ração, conversão alimentar, espessura de toucinho e parâmetros bioquímicos sanguíneos - ureia, proteínas totais, creatinina, glicose, triglicerídeos e colesterol. Para as características de carcaça foram avaliados: peso nas carcaças quente e fria, rendimento nas carcaças quente e fria, pH e temperatura nas carcaças quente e fria e peso de cortes industriais. Para o desempenho econômico foi calculado o custo da ração, custo do kg suíno e índices de custo médio e de eficiência econômica. Foi utilizada análise de regressão para as variáveis produtivas. Não foram encontrados efeitos para o desempenho e características de carcaça. Nas variáveis bioquímicas, foram encontrados efeitos lineares para a ureia e proteínas totais, com os animais com 0% de sorgo apresentando os maiores valores. Quanto ao desempenho econômico, o grupo com 50% de sorgo apresentou o menor índice de custo e o maior de eficiência econômica. Dessa forma, conclui-se que a substituição do milho pelo sorgo granífero em níveis de até 50% da dieta representa uma alternativa sustentável na suinocultura regional.

TRANSMISSION OF KNOWLEDGE ABOUT SOME ZOONOSES IN STUDENTS OF PUBLIC SCHOOLS IN THE MUNICIPALITIES OF APODI, FELIPE GUERRA E SEVERIANO MELO (RN) -BRAZIL ABSTRACTThis study aimed to assess the knowledge of students from public schools on some Zoonosis, through presentation given by students of Animal Science Technician. 677 questionnaires were administered to public students in cities of Apodi, Felipe Guerra and Severiano Melo. The questionnaires were administered before and after. The data were discussed through a descriptive analysis. The main results showed that the content of transmission and prevention of some zoonosis are fixed. Before the presentation 20.8% of students did know the concept of Zoonosis and after, this percentage increased to 88.3%. There was an increase in knowledge of transmission form of larva migrans, toxoplasmosis and leptospirosis, where before the presentation the percentage was 91.8, 1.9 and 29.4% and after was 100.0, 57.8 and 72.4%, respectively. For the transmission of intestinal worms, the percentage fixation of knowledge was not altered significantly before (86.5%) and after (87.9%) presentations. The conclusion is that the methodology of presentation to students in public education is a tool that can be used as a form of education and disease prevention.

RESUMO PROFILE AND EXPECTATION OF THE STUDENTS CONCLUDING OF THE COURSE TECHNICIAN OF IFRN, CAMPUS APODI ABSTRACTThis study aims to characterize the profile and expectations of students in third and fourth years of integrated technical courses in Animal Science and biofuels, from Federal Institute of Education, Science and Technology of Rio Grande do Norte -Campus Apodi. The survey was conducted with 138 students, through the use of questionnaires with open and closed questions. Data analysis was performed descriptively and presented in percentage. The main results showed that women are the majority (60.9%) and the average age was 17.4 years. 99.3% of students said they want to attend college and the Federal University of Rio Grande do Norte was mentioned institution. The courses most frequently cited by students were: Medicine, Science and Technology, Chemical Engineering, Civil Engineering, Law and Veterinary Medicine. As a professional practice, 89.9% of students performing in the form of research projects or extension and 10.1% in the form of internships. Over 97% of students are satisfied with the disciplines, but 64.5% are not satisfied with the amount of practical classes of the courses. As for the labor market, 58.8% believe that there are good opportunities. Thus, are necessary measures to qualify the student teaching, however, depend on the same of a democratic management to consider the opinion of the whole school community.

This objective of this work was to assess the knowledge of students in public schools about rabies and leishmaniasis, through educational interventions. A total of 628 questionnaires were applied in public students from Apodi, Felipe Guerra and Severiano Melo. The questionnaires were administered before and after the educational interventions in the form of lectures. The data were discussed through a descriptive analysis. Before the presentation, 53.9% of students claimed to know the transmission mode of leishmaniasis and after, this percentage increased to 92.2%. However, before the lectures, only 6.0% of respondents associated the transmission to sandflies, and after, this percentage increased to 75.7%. For rabies, before the lectures, 63.7% of students reported knowing how rabies is transmitted and, after the lectures, 92.8% said how it was the transmission. Concerning the transmission, before the presentations, 68.3% reported that it was through bite or injury of animals and, after the lectures, the index increased to 80.4%. In conclusion, the student´s perception of public education on rabies and leishmaniasis was higher in all aspects addressed after educational intervention compared to the same questions about the knowledge of the disease before the intervention. It also concludes that the perception of students for rabies is greater than for leishmaniasis.KEYWORDS: education, school, extension, public health, zoonoses.

ResumoDiversos trabalhos têm demonstrado diferenças na qualidade espermática do sêmen descongelado entre diversos reprodutores suínos, demonstrando variações na resistência individual dos espermatozóides destes animais ao processo de congelação. Este trabalho teve por objetivo testar o sêmen proveniente de diferentes reprodutores para se identificar sensibilidades individuais ao processo de congelação. Quatro machos foram coletados, em recipiente de 500 mL coberto por gaze para separação da parte gelatinosa e protegido por envoltório térmico. Cada amostra continha 112 x10 6 sptz/mL para as análises in vitro. A técnica de Paquignon foi utilizada para a congelação do sêmen. Após a descongelação, a 37 o C durante 30 segundos, o conteúdo de cada palheta foi ressuspenso após descongelação no diluente Beltsville Thawing Solution (BTS). Foram avaliadas em microscopia óptica o vigor e a motilidade espermática após descongelação (M1), ressuspensão (M2) e 10 minutos (M3) e 2 horas de incubação (M4) a 37 o C. A morfologia do acrossoma foi analisada em esfregaço de sêmen feito em M3. Foi utilizado o teste de Mann Whitney através do General Linear Models do programa Statistical Analysis System (SAS 6.03, 1988) a 5% (p<0,05).Palavras-chave: varrões, sêmen, congelação, espermatozoides, sensibilidade. AbstractSeveral works have been demonstrating differences in spermatic quality of the thawed semen among several swine males. Variations are diagnosed in the individual resistance of the spermatozoids of these animals to the freezing process. This work had for objective to test the semen from the different boars to identify individual sensibilities to the freezing process. Four males were collected, in recipient with 500 mL covered by filter for separation of the gelatinous part and protected by thermal wrapper. Each sample contained 112 x10 6 sptz/mL for the in vitro analyses. The Paquignon technique was used for the semen freezing. After descongelation at 37 o C during 30 seconds, the content of each slat was diluted in Beltsville Thawing Solution (BTS). They were analysed in optical microscopy, the vigour and the spermatic motility, after descongelation (M1), dilution (M2) , 10 minutes (M3) and 2 hours of incubation (M4) at 37 o C. The acrossome morphology was analyzed in M3. The Mann Whitney's test was used with the Lineal General Models in Statistical Analysis System Program (HEALTHY 6.03, 1988) at 5% (p<0,05).

A presente pesquisa avaliou o perfil profissional e as atribuições do Técnico em Zootecnia (TZ) frente ao Técnico em Agropecuária (TA) e ao Zootecnista. Para desenvolvê-la, foram consultadas as legislações pertinentes e bibliografias pedagógicas dos cursos. Os resultados mostram que a atividade do TZ e do TA são correlacionadas, em que a atuação do TZ ocorre para a produção animal e a do TA para a produção animal e vegetal. Entre os cursos de TZ e o Bacharel em Zootecnia, o curso de graduação tem longa duração e conteúdos aprofundados, já o técnico possui durabilidade menor e conteúdo mais superficial. Conclui-se que as legislações que tratam dessas profissões no Brasil causam concomitância de atribuições entre os profissionais, dessa forma, o próprio mercado selecionará o profissional baseado na qualidade do serviço.   Palavras–chave: Mercado profissional.
