The objective of this study was to evaluate the canopy structure and performance sheep raised on massai grass during dry season in response management adopted wet season. treatments consisted two targets light interception (90 95%) post-grazing heights (15 25 cm) a 2 x factorial scheme. Pastures were managed season, while continuous stocking used following pasture characteristics evaluated: height, forage mass, leaf blade, stem dead matter blade:stem ratio, crude protein, neutral detergent...
This paper aimed to evaluate the dynamics of tillering, tiller density and structural characteristics Brachiaria brizantha, Panicum maximum Cenchrus ciliaris under a cutting regime.The utilized design was randomized blocks with six treatments (cultivars) three replications.The evaluations were conducted from May September 2011, data grouped into two periods, rainy season beginning dry season.The greatest population observed in Massai cultivar, averaging 1,019 tillers.m -2 .The mortality rate...
Studying the dynamics of gross primary production (GPP) in seasonally dry tropical forests is fundamental importance to understand carbon dioxide (CO2) balance this ecosystem, helping mitigate its potential impacts at regional and global levels. Thus, objective work was evaluate accuracy GPP estimated via remote sensing Caatinga biome. A set observed data retrieved from micrometeorological towers equipped with eddy covariance systems were used validate data. The measured a preserved...
Abstract This study aimed to evaluate the agronomic and structural characteristics of massai grass under grazing by sheep supplemented in dry season. The treatments were supplements offered pastures: multiple mixture, leucaena hay, gliricidia hay soybean meal. pastures evaluated regarding: canopy height; forage accumulation mass; accumulation, mass percentage morphological constituents; leaf:stem green mass:dead material ratio; pre‐ post‐grazing bulk density. Higher pre‐grazing heights...
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...
The low quality of tropical grasses in the dry season justifies use dietary supplements to meet nutritional needs sheep. objective this study was evaluate effect supplementation with high-protein feed on mutton sheep performance and yield Massai grass pastures during season. treatments corresponded four supplements, namely Leucaena leucocephala leaf hay, Gliricidia sepium soybean meal, a treatment that received only multiple mixture (protein salt) ad libitum. pasture evaluated for canopy...
The objective of this study was to evaluate the biometry and carcass characteristics finished Santa Inês crossbred sheep grazed on tropical grass pastures during dry season.The carried out at Grupo de Estudos em Forragicultura (GEFOR/UFRN), in Macaíba -RN, Brazil.Four forage treatments were evaluated: Brachiaria brizantha cvs.Marandu e Piatã, Panicum maximum cvs.Aruana Massai.The 2.88 ha-area used divided two blocks 1.44 ha; each one composed four plots corresponding cultivar, plot...
Cultivated pastures may increase the meat production of sheep, but it is necessary to understand plant-animal relationships in a pastoral environment. This study aimed assess effect forage cultivars on intake and feeding behavior sheep. Four treatments were evaluated, consisted Panicum maximum cvs. Aruana Massai Brachiaria brizantha Marandu Piatã. Twenty-four male Santa Inês genotype, used with six replications per treatment. Daily nutrient intakes evaluated addition time grazing,...
The ingestive behavior of sheep supplemented with concentrate in Brachiaria brizantha and Panicum maximum pastures were evaluated during the dry season.Twenty four male ½ Santa Inês x undefined breed genotypes used.The treatments feeds cultivar grasses: B. cvs.Marandu Piatã, P. cvs.Massai Aruana.The animals was recorded two periods 24 hours.The grazing time, rumination, idleness (minutes day -1 ), bite rate (bites minute frequency activities relation to defecation, urination search for...
This research builds on 20 years of combined experience in economics and art, exploring how economic relational systems shape emotional landscapes. The study investigates the intersection art economy through lens love, using resonance affect to understand their dynamics. With a focus nomadic practices exemplified by Lisbon Drawing Club, examines community-oriented fosters bonds responses, particularly drawing sessions. Employing autoethnographic desire-based approaches, project integrates...

Objetivou-se com essa pesquisa avaliar as características de carcaça e qualidade da carne coelhos machos fêmeas raça Lionhead. Foram utilizados 20 ambos os sexos, quais constituíram tratamentos. Os animais foram alimentados ração concentrada, volumoso água à vontade durante 60 dias. Houve pesagem semanal dos até o término do período arraçoamento, quando então, submetido ao abate. O delineamento estatístico adotado foi inteiramente casualizado aplicado teste Tukey para avaliação das médias....
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...
The intercropping of corn and grass allows for the production grains, simultaneously, recuperation renovation pastures. This study aimed to evaluate effects N doses on yield, structure, chemical-bromatological characteristics, use efficiency Brachiara brizantha cultivars in an integrated crop-livestock system. experimental design was completely randomized, with four replications, a slip-plot scheme. plots were formed two plants, Marandu Paiaguás, intercropped subplots composed nitrogen (70,...
