The objective was to evaluate sowing density influence on hydroponic corn fodder bromatological composition, harvested in different ages raised on grass mix substrate. The experimental design used was completely randomized with six replications for each treatment, using 2.0 m² plots (1.0 x 2.0 m). The densities were distributed into factorial array (4x4), consisting in four sowing densities (1.0, 1.5, 2.0 and 2.5 kg m-²) and four cutting ages (10, 15, 20 and 25 days). The dry matter content (DMC) and production (DMP) and crude protein (CP), acid detergent fiber (ADF), Fiber neutral detergent (FND) and ethereal extract (EE) were analyzed each cutting age. In terms of DMP (kg m-²), EE (%) and DMC (kg m-²), it is recommended to use the density 1.0 kg m-² with cutting age of 25 days. Regarding CP (%) the best result was at 15 days of cut and density 2.5 kg m-² and the values for FND (%) and ADF (%) were higher at 25 days at 2.0 kg density 2,0 kg m-². The choice of both best harvesting age and density will depend on what is desired of the nutritional forage (CP, EE, NDF, ADF, DMC and DMP) as well its destination, since very close values were found in all analyzes, regardless of density and age of harvest analyzed.

Ovinos são comumente acometidos por parasitoses gastrointestinais, a maioria cosmopolita, sendo Haemonchus sp., o nematódeo encontrado com maior frequência parasitando os ovinos, que se contaminam ingerindo as larvas. Isso implica na importância de se conhecer o ciclo de vida deste parasito, que é um micoorganismo microscópico que se aloja no trato gastrointestinal e absorve o sangue ocasiona o quadro de anemia, fato este que pode debilitar rapidamente o animal e causar o óbito, além de provocar um atraso no desenvolvimento do animal, gerando perdas econômicas. Foi utilizado neste estudo a metodologia da revisão bibliográfica, procedente de artigos científicos e livros. O H. contortus é a espécie de maior relevância, pois tem alta patogenicidade e alta prevalência nos rebanhos brasileiros, causando perdas econômicas ao produtor devido à baixa produtividade e desenvolvimento dos animais acometidos, como perda de peso, anemia, atraso no desenvolvimento corporal de animais jovens e, causando o óbito.  O uso indiscriminado de antiparasitários causou o aumento da resistência dos helmintos às moléculas existentes no mercado. Desta forma, a necessidade de buscar novos métodos de controle de verminoses visa diminuir o uso de anti-helmínticos por meio da vermifugação seletiva, alimentação balanceada com suplementação proteica e o fornecimento de forrageiras de boa qualidade e com altos teores de proteína.

A systematic review of the literature was carried out to perform a meta-analysis to assess effects of age at weaning on the performance of piglets in the range of 14 to 42 days old. This step consisted in defining the databases and keywords to be employed in searching for papers for the meta-analysis. To that end, the databases Capes Publication Portal and Google Scholar were searched for researches published from 2001 to 2019. After the acceptance and exclusion criteria had been defined and applied, 28 papers were selected. The data were collected with Excel® software of Microsoft Office for later statistical analysis. Orthogonal polynomial contrasts were used and the linear and quadratic regression equations were fitted with hypotheses tested at the 5% significance level. The results confirmed the disadvantages of early weaning and the benefits of weaning at around 28 days old. In the farrowing phase, piglets weaned after 35 days had lower daily weight gain (DWG) (P =0.002) than those weaned at 27 days. The derivative of the regression of DWG while nursing on age revealed that a weaning age of 26.34 days yielded the maximum DWG among the ages assessed. After weaning, the maximum DWG was achieved by weaning piglets at 32.26 days. Given the performance of piglets in the farrowing and nursery phases, the results of this meta-analysis indicated the best weaning age was between 26 and 32 days.

The present study aimed to evaluate carcass, cut yields and gastrointestinal tract biometry, the meat quality and body lesions of broiler chicken fed with four levels of corn distillers dried grain with soluble in experimental diets. A total of 700 day-old mixed flock Cobb 500 broiler chicks were distributed in a completely randomized design with five treatments, seven replicates by treatment with 20 birds each. The experimental diets were controlled with crescent inclusion levels of DDGS (4, 8, 12 and 16 %). At 35 days of age 2 broilers from each lot was selected, weighted and identified with medium weight from the experimental unit for slaughtering and evaluation of cuts yield, carcass and gastrointestinal biometry. To evaluate hock lesions and broiler meat quality. Quadratic effect was observed in reference to the weight of the carcass and chest can be included the levels up to 11.29 percent and 6.16 percent respectively. For the other variables of income of casting, edible organs and not edible and there was no significant effect on gastrointestinal biometrics, only for the total size of the gastrointestinal tract there was quadratic effect being the level of 4.25% indicated for increased size of the organs. For all welfare and meat quality variables evaluated, there was no difference between the DDGS levels used in broiler diets and control diet. These findings means that the addition of up to 16 % DDGS in diets can be an alternative to feed chicken without inducing body lesions neither altering broiler meat quality.

A produção e o consumo de carne de frango tem crescido muito durante os últimos anos. Com isso os consumidores e os produtores de frango passaram a se preocupar mais com cada processo produtivo da cadeia avícola, visando assim um produto final de boa qualidade. Assim, objetivou-se avaliar o perfil dos produtores e consumidores de frangos tipo caipira da Região do Alto São Francisco – MG. A pesquisa foi realizada no município de Bambuí – MG, situado no centro oeste mineiro. Participaram do questionário 60 bambuienses abordados em diferentes supermercados da cidade, feiras-livres, e nas próprias residências, onde foram utilizados questionários já pré-definidos. A análise dos dados foi realizada com o auxílio de planilhas eletrônicas, sendo utilizado o Microsoft Office Excel® 2007. Os consumidores de carne de frango caipira estão interessados em saber a origem do produto, bem como a garantia de um produto saudável, com preço acessível, e de qualidade. O sabor do frango caipira ainda é o fator determinante pra quem procura esse tipo de alimento. Pode-se observar com a pesquisa que a produção de frango caipira é uma atividade com grande potencial de venda, mas ainda carece de ferramentas relacionadas a melhoria do processo produtivo, que impulsionem os criadores a trabalharem com mais qualidade. A produção de qualquer produto de origem animal precisa cada vez se adequar as normas de bem-estar, uma realidade que poucos produtores conhecem.
