Abstract: the objective of this study was to evaluate the performance of three nile tilapia oreochromis niloticus strains cultivated in cages and subjected to different feeding programmes. initially, 31,200 nile tilapia juveniles with an average weight of 61.15 g were distributed in 48 cages. two genetically improved strains were used together with one from the fish culture section of universidade federal de lavras (ufla). the fish were subjected to four feeding programmes, consisting of different levels of crude protein (cp) in diets provided at different stages of cultivation. there was no interaction effect of the strain and feeding programme for most variables. the ufla strain presented the highest weight gain, but with greatest lack of uniformity at the end of cultivation. the feeding programme with diets containing 36%, 32% and 28% cp, consecutively, promoted the highest weight gain and highest final biomass. the ufla strain has great growth potential, justifying the development of a breeding programme for this strain. crude protein levels below 36% for tilapias between 60 and 170 g and below 32% for tilapias between 170 and 700 g worsen fish performance.

Abstract: a total of 144 crossbred piglets were utilized, being 72 castrated males and 72 females, with average initial weight of 6.91kg ± 1.32 kg, at 28 days old, to determine the effect of the addition or not of two sources of lipids (soybean oil and coconut oil) at different levels (2, 4, 6 and 8%) over pigs performance (daily average weight gain, daily average feed intake and feed conversion). it was utilized a randomized block design using a factorial arrangement 2 x 4 (sources and oils levels) and an additional treatment (control ration without lipids addition). the experimental rations were isocaloric, isoprotein and isolysine, formulated based on corn, soybean meal, skimmed milk powder fish meal supplemented with minerals, vitamins and lysine. there was no significant interaction between sources and oils levels tested (p>0.05) for none of the performance parameters studied. significant difference was not observed (p>0.05) in the daily average weight gain of pigs receiving or not soybean oil or coconut oil, in different levels. comparing the means of treatments (2, 4, 6, 8% soybean oil and coconut oil) with the control ration (without lipid addition), it was observed larger (p<0.01) daily average feed intake and worse (p<0.01) feed conservation when lipid was not added to the diet. the addition of lipids in the piglets diets is beneficial due to smaller ration intake for a same weigh gain and better feed conversion.

Abstract: Um dos objetivos específicos do Programa de Assistência Integral a Saúde da Mulher é a amplia o e qualifica oclínico-ginecológica, inclusive para cuidar das portadoras de infec o pelo HIV e outras DST’s, por meio de estratégiasque favore am o fortalecimento da aten o básica. Este estudo teve o objetivo de analisar a opini o de mulheres,assistidas pelo PSF e CTA do município de Bayeux-PB, quanto às orienta es fornecidas por profissionais de saúde emrela o ao HIV/AIDS. Estudo exploratório de abordagem qualitativa, realizado em 2006, que contou com aparticipa o de 22 mulheres. Os dados foram analisados por meio da técnica do Discurso do Sujeito Coletivo eapresentados em quadros. Identificou-se que as mulheres tinham faixa etária variando entre 19 e 60 anos, e 82%referiram ter o primeiro grau incompleto. De acordo com os discursos pode-se evidenciar que n o está havendocontinuidades nos trabalhos de orienta o sobre DSTs/AIDS na aten o básica; Houve satisfa o quanto asorienta es obtidas no CTA; Identificou-se impedimentos para o uso do preservativo. Acredita-se que elas necessitamde assistência em espa os educativos. Todavia para que haja mudan a nas práticas assistenciais dos profissionais, é primordial o envolvimento da equipe gestora.
