This work proposes the manufacture of bioplastics for food packaging using starch, carboxymethylcellulose, and green coconut waste (Cocos nucifera), with addition acid-base mediators to indicate pH food. The method was based on experimental research, in which films were produced casting technique incorporated at a concentration 1% (v/v). results showed high percentage solubility, an average 95.09%, low moisture content dry basis, 0.95%, presented visually noticeable colorimetric changes...
The objective was to evaluate the productive and structural characteristics of tropical grasses performance sheep supplemented during dry season. treatments consisted Marandu, Piatã, Massai Aruana cultivars managed under intermittent stocking with seven occupation days 35 d rest, a variable rate. evaluated variables were forage masses, morphological components, chemical composition pasture performance. mass similar among cultivars, while leaf blade percentage higher in cultivar. There...
ABSTRACT The objective of this study was to evaluate the effect different protein sources on performance lamb ewes and their offspring supplemented in deferred pasture. treatments were sources: soybean meal, cotton cake, babassu cake coconut cake. weighed evaluated for body condition score during gestation, parturition weaning phases. lambs at birth weaning. structural variables chemical composition pasture usage period. Grass height forage mass higher when gestation stages. leaf not altered...
The production of ruminants in Brazil is based exclusively on grazing, since they are able to provide low cost energy substrates, mainly from fibrous carbohydrates. However, forage plants most cases when used as an exclusive source the ruminant diet do not meet requirements animal due recognized fluctuation nutritional requirements, which compromises yield, signaling need supplement animals, for purpose providing nutrients that limiting performance. Supplementation should be maximize...
Na regiao Nordeste, a irregularidade de chuvas ao longo do ano torna-se um dos principais fatores que podem interferir na produtividade e qualidade da forragem. Diante disto, o objetivo deste trabalho foi avaliar efeito epoca nas caracteristicas morfogenicas seis cultivares forrageiras (Aridus, Biloela, Massai, Mombaca, Piata Xaraes) sob as condicoes edafoclimaticas Nordeste. O delineamento experimental em blocos acaso com tres repeticoes tratamentos. As avaliacoes foram realizadas entre...
O objetivo deste trabalho foi avaliar a estrutura do pos-pastejo de gramineas dos generos Panicum e Brachiaria na epoca das aguas. A desfolhacao realizada por ovinos deslanados, altura estabelecida para o pos pastejo 25 cm. Os tratamentos constituiram quatro cultivares: Marandu, Aruana, Piata Massai. Avaliou-se as massas forragem componentes morfologicos. massa no da cv. Massai superou cvs. Aruana Piata, todas os valores foram considerados altos. maior lâminas foliares observada Massai, dada...
A batuíra-bicuda (Charadrius wilsonia) tem uma ampla distribuição, ocorrendo em variedade de habitats costeiros e insulares da Costa do Atlântico Pacífico, América Norte ao Peru Brasil. Esta ave limícola é considerada “Vulnerável” no Brasil, existe pouco conhecimento sobre o status reprodutivo, abundância distribuição espécie na Sul. Realizamos censos mensais setembro 2011 a 2012 janeiro 2016 dezembro 2017 diferentes um transecto praia 10 km região Bacia Potiguar, nordeste para suprir essa...
