Abstract: Fruit growing has achieved advances through the use of new technologies generated by research. In Brazil, it is one of the most prominent sectors in agribusiness, achieving significant results and generating business opportunities. In this way, the fruit market has grown considerably in the last decades, both in quantity and in quality. Allied to this, the changes in consumer behavior regarding food consumption have been responsible for the increase of the fruit market. The objective of this work was to know the evolution of the fruit trade in the city of Lavras, state of Minas Gerais, Brazil, in relation to the quantity sold, monetary value, losses in the gondolas of retail establishments and per capita consumption of the population of this city.

Abstract: O objetivo desse trabalho foi avaliar a substitui o parcial do farelo de soja por nitrogênio n o protéico no desempenho de vacas holandesas em lacta o. Oito animais com 90 dias de lacta o e 600 kg de peso vivo, no início do experimento, foram distribuídos em dois quadrados latinos (4X4). A uréia representou 0,0; 0,8; 1,54; e 2,40% da matéria seca (MS) da dieta, correspondente a 2,32; 4,65; 6,66; e 8,02% de proteína bruta (PB) na forma de compostos nitrogenados-n o-protéicos (NNP), que representaram os tratamentos experimentais. O consumo de PB apresentou comportamento quadrático, com valor máximo de 3,3 kg/dia para o nível de 4,71% de NNP. O consumo de cálcio (Ca) aumentou e o de matéria seca (MS); matéria organica (MO); extrato etéreo (EE); carboidratos totais (CHT); carboidratos-n o-fibrosos (CNF); fibra em detergente ácido (FDA) e nutrientes digestíveis totais (NDT) diminuíram linearmente, enquanto os consumos de fibra em detergente neutro (FDN) e de fósforo (P) n o foram influenciados pelos tratamentos experimentais. As produ es de leite sem e com corre o para 3,5% de gordura diminuíram linearmente com a inclus o de uréia e palma forrageira nas dietas. A produ o de gordura, proteína, a composi o do leite, e a eficiência alimentar (kg de leite/ kg de MS consumida) n o foram afetadas pelos níveis de NNP.

Abstract: Castor bean hulls (CBH), co-products of castor oil extraction, are high in dry matter (DM) and fiber and are emerging as alternative roughage in sheep feed. This could reduce feed costs since other sources of roughage can be more expensive. The effects of replacing Tifton 85 hay with CBH at 0, 33, 66 and 100% in the diet of sheep on the carcass characteristics, weights and yields of retail cuts and carcass measurements were studied. Twenty-eight non-castrated sheep averaging 7 ± 1.4 months of age with an initial weight of 19.5 ± 4.3 kg were slaughtered after 70 days of confinement. There was a linear decline (P ≤ 0.05) in slaughter body weight, empty body weight, hot and cold carcass weight and longissimus muscle area (LMA) as the percentage of dietary CBH increased. A linear decrease (P≤0.05) of the weights of all retail cuts and a quadratic effect (minimum yield of 9.84% with the replacement of 56.9%) of the neck yield were also detected as the percentage of CBH increased. No treatment effects (P > 0.05) on the yield of the other cuts were observed, but there was a linear decline (P ≤ 0.05) in the perimeters of the thorax, leg and rump and the carcass compactness index. Replacing Tifton 85 hay with CBH in sheep diets is not recommended because it decreases the slaughter body weight, cold and hot carcass weight, retail cut weights and morphometric measurements. A casca da mamona, coproduto da extra o do óleo da mamona, por apresentar em sua composi o elevados teores de matéria seca e fibra, surge como fonte alternativa de volumoso na alimenta o de ovinos, podendo diminuir os custos com alimenta o, uma vez que outras fontes s o comercializadas a pre os superiores. Avaliou-se o efeito da substitui o do feno de capim Tifton 85 pela casca de mamona em 0, 33, 66 e 100% na dieta de ovinos sobre as características de carca a, os pesos e rendimentos dos cortes comerciais e a morfometria da carca a. Vinte e oito animais n o castrados, com 7 ± 1,4 meses de idade e peso inicial médio de 19,5 ± 4,3 kg, foram abatidos após 70 dias de confinamento. Houve efeito linear decrescente (P≤0.05) para o peso corporal ao abate, peso de corpo vazio, peso de carca a quente, peso de carca a fria e área de olho-de-lombo, de acordo com os níveis crescentes de substitui o. O decréscimo linear (P≤0,05) no peso de todos os cortes comerciais e o efeito quadrático do rendimento do pesco o (rendimento mínimo de 9,84% quando a substitui o foi de 56,9%) também foram verificados com o aumento percentual da casca de mamona. N o houve efeito (P > 0,05) sobre os rendimentos dos demais

Abstract: the brazilian semi-arid region has 928 km2 ranging from the northern portion of minas gerais and espirito santo states, the semi-arid lands of bahia, sergipe, alagoas, pernambuco, paraíba, rio grande do norte, ceará, and piauí states, and 45 counties from southeastern maranh?o state. population is mainly concentrated in rural areas and the major occupation is agriculture and livestock production. dairy production is one of the few options in these areas, mainly in northeast brazil, where the feeding systems are based on cultivated forage crops and use of native vegetation, predominately the "caatinga". these aspects give seasonal characteristics for the production on this region. inadequate amount and distribution of rainfall in this region presenting strong spatial and seasonal variability and prolonged dry periods practically determines the need for supplementation feeding for dairy cows for production systems located in the semi-arid region. thus, supplementation has been based on the use of forage resources adapted to the drought, by-products, residues from local agro-industry, and on concentrate feeding. farmers are also using different options trying to reduce costs without losing productivity during the dry periods. production systems such as "cbl" (caatinga-buffel grass-leucaena) and "gloria system" have been proposed aiming to alleviate the adversities. in addition to these systems, the utilization of agro industrial by-products, crop residues, and native forage resources are important options. in this aspect, the forage cactus (opuntia ficus-indica mill.) deserves special attention for its great adaptation, nutritive value, and productivity in the region.

Abstract: Objetivou-se avaliar o efeito da substitui o do milho e farelo de soja por levedura de cana-de-a úcar e uréia, sobre o consumo de nutrientes, digestibilidade e desempenho, em ovinos. Foi avaliada a inclus o de 0; 10, 20 e 30% de levedura corrigida com uréia. Foram distribuídos, aleatoriamente, 32 ovinos castrados nos quatro tratamentos, num delineamento inteiramente casualizado. Os consumos de matéria seca, matéria organica, extrato etéreo, proteína bruta e carboidratos totais n o foram influenciados, pela inclus o de levedura na dieta. Os consumos de carboidratos n o-fibrosos e NDTdiminuíram, e o de fibra em detergente neutro aumentou linearmente com a inclus o de levedura. A digestibilidade da proteína bruta, extrato etéreo, fibra em detergente neutro e carboidratos totais n o foram influenciados, enquanto que a digestibilidade da matéria seca,matéria organica e carboidratos n o-fibrosos diminuíram linearmente com a inclus o de levedura. Os pesos ao abate, da carca a fria e quente, ganho de peso, rendimento de carca a fria e quente e perda ao resfriamento diminuíram linearmente com a inclus o de levedura.O rendimento dos cortes comerciais n o foi alterado pela inclus o de levedura. Conclui-se que a substitui o do milho e farelo de soja por levedura e uréia, na dieta de ovinos, afetou negativamente o consumo de energia e o desempenho animal. This study was conducted to determine the effects of the replacement of cracked corn and soybean meal with sugar cane yeast and urea on nutrient intake, digestibility and performance of sheep. The additions of 0, 10, 20 and 30% of sugar cane yeast enriched withurea were evaluated. Thirty-two castrated male sheep were assigned to the four treatments in a completely randomized design. The results showed that intakes of dry matter, organic matter, crude protein, ether extract and total carbohydrates were not affected by sugar caneyeast. However, intake of non-fiber carbohydrates and TDN decreased, and neutral detergent fiber intake increased linearly when the level of sugar cane yeast increased. The digestibility of crude protein, ether extract, neutral detergent fiber and total carbohydratewere not affected, while the digestibility of dry matter, organic matter and non-fiber carbohydrates decreased linearly as a function of sugar cane yeast levels. Slaughter weight, hot and cold carcass weight, live weight gain and both hot and cold carcass dressingdecreased linearly as functions of levels of sugar cane yeast. The dressing of commercial cuts, as a function of cold carcass, was not affected by sugar cane yeast. It w

Abstract: O experimento foi realizado de janeiro a abril de 2005, objetivando avaliar o comportamento ingestivo e os parametros fisiológicos de vacas da ra a Holandesa em lacta o, alimentadas com concentrado e palma forrageira associada a diferentes volumosos (baga o de cana-de-a úcar in natura, feno de capim-tifton, feno de capim-elefante, silagem de sorgo e baga o de cana mais silagem de sorgo). Foram utilizadas cinco vacas, distribuídas em quadrado latino 5 x 5, após período pré-experimental de quatorze dias. Cada período experimental teve dura o de 14 dias. O registro das variáveis comportamentais foi de forma visual, em intervalos de cinco minutos, em 24 horas. O ambiente foi monitorado de hora em hora, das 6h às 18h, por meio dos term metros de bulbo seco e úmido. A temperatura retal e freqüência respiratória foram registradas às 9h e 18h. O consumo de água foimensurado às 5h30min e 17h30min. N o houve diferen a (p > 0,05) entre os volumosos, quanto às variáveis fisiológicas e comportamentais, ao número de defeca o e mic o e a procura por água. Houve diferen a (p < 0,05) entre os tratamentos para o consumo de água da tarde e total. Nestas condi es, a associa o da palma forrageira com os diferentesvolumosos n o influencia as variáveis comportamentais, fisiológicas e influencia a ingest o de água. The experiment was carried out from January to April 2005, evaluating the ingestive behaviour and physiologic parameters of lactating Holstein cows fed with cactus forage associated with different forage (sugarcane bagasse in natura, tifton grass hay, elephant grass hay, sorghum silage and sorghum silage plus sugarcane bagasse). Five cows were assigned to a 5 x 5 latin square design, after pre-experimental period of 14 days. Each experimental period lasted 14 days. The registration of the behavior variables was in a visual way, at five-minute intervals, in 24 hours. The ambient temperature was monitored every hour, from 6 am to 6 pm, through bulb dry and humid thermometer. Rectal temperature and respiratory frequency were registered at 9 am and at 6 pm. The water intake was measured at 5.30 am and at 5.30 pm. There was no difference (p > 0.05) among the forage, as for physiologic variables, behavior, defecation, urination and seek for water. Yet, there was difference (p < 0.05) among the treatments for the afternoon and total water intake. Under these conditions, the association of cactus forage with sugarcane bagasse, tifton grass hay, elephant grass hay, sorghum silage and sorghum silage plus sugarcane bagasse, did not influence behavior, physiologic variabl

Abstract: O trabalho teve como objetivo avaliar a produ o, composi o e o perfil de ácidos graxos do leite, parametros fisiológicos e atividades comportamentais de vacas da ra a Pitangueiras, submetidas à condi o de pastejo com e sem acesso à sombra. O ambiente foimonitorado diariamente em uma esta o meteorológica. O delineamento experimental foi o inteiramente casualizado, sendo que 20 vacas em lacta o foram divididas em piquetes nos tratamentos com e sem acesso à sombra. N o houve diferen a (p > 0,05) entre os tratamentos quanto às variáveis fisiológicas, produ o, composi o e perfil de ácidos graxos do leite. Os animais com acesso à sombra buscaram o sombrite nos horários em que os índices de conforto térmico foram mais elevados. No turno da tarde os parametros fisiológicos foram mais elevados que no turno da manh . O uso do sombrite foi favorável em rela o ao ganho de peso dos bovinos leiteiros e perfil de ácidos graxos de cadeia longa, quando os índices de conforto térmico foram elevados. Nessas condi es, sua utiliza o é recomendada para vacas da ra a Pitangueiras em sistema de pastejo. The objective of this trial was to analyze milk production, milk composition, fatty acid profile, physiological parameters, and behavior of Pitangueiras cows under grazing conditions and submitted to the presence or absence of shade in the paddock. The environment was monitored daily using a meteorological station at the research site. A complete randomized experimental design was used and 20 lactating cows were allocated in paddocks with or without shade. Daily milk productivity did not differ among cows. There was also no difference in the fatty acid profile and milk composition. Cows with shade available stayed under the shade during periods where thermal comfort index was greater. Physiological responses did not showsignificant differences; however, differences were observed between morning and afternoon periods, with greater values observed for the afternoon period. The use of artificial shade favored animal weight gain and long-chain fatty acid profile under high thermal comfortindex. In this condition, the shade to Pitangueiras cows breed is advised.
