Revista Brasileira de Zootecnia , 2001,
Abstract: O trabalho foi conduzido na Embrapa Caprinos, em Sobral, Ceará, com o objetivo de avaliar os efeitos do corte da parte aérea em rela o à altura da rebrota na sobrevivência, persistência e no vigor da rebrota do marmeleiro e produ o subseqüente de fitomassa do estrato herbáceo. O corte das plantas foi realizado a 10,0 cm de altura, quando suas rebrotas alcan aram quatro diferentes alturas (25, 50, 75 e 100 cm). Os tratamentos de corte foram aplicados em parcelas de 5 m x 30 m. A avalia o da mortalidade das plantas foi realizada mediante a contagem de todas as plantas mortas e vivas dentro das parcelas experimentais. Os dados foram analisados por intermédio do teste n o-paramétrico do qui-quadrado. Verificou-se que houve dependência entre a mortalidade das plantas e o corte das rebrotas e que todos os tratamentos foram diferentes entre si. O melhor resultado foi alcan ado quando as rebrotas foram cortadas à altura média de 75 cm, diminuindo a densidade do marmeleiro em até 96%. A redu o da densidade proporcionou aumentos significativos na produ o de fitomassa herbácea, em rela o à área n o tratada.

Abstract: Objetivou-se avaliar a composi o química, digestibilidade e o consumo da vegeta o herbácea de uma Caatinga raleada e enriquecida com capim buffel (Cenchrus ciliaris L.) pastejada por ovinos e caprinos. Foram utilizados 12 caprinos F1 (B er x SRD) e 12 ovinos Santa Inês com peso vivo médio de 15kg. Os dados da vegeta o foram analisados através de delineamento inteiramente casualizado com observa es repetidas no tempo, e os de consumo dos animais foram em delineamento inteiramente casualizado com dois tratamentos e 12 repeti es. O pastejo n o afetou a composi o química e a digestibilidade in vitro da vegeta o herbácea. Em avalia o do dia 01 de junho os três componentes florísticos apresentaram os menores percentuais de matéria seca e os maiores de teores de proteína bruta e digestibilidade in vitro da matéria seca. Entretanto ocorreu o inverso em 01 de agosto, que diferiu até mesmo do observado em 01 de setembro e 01 de outubro. Os caprinos apresentaram consumo de 437,47g de matéria seca, superior aos 331,78g de matéria seca ingerida pelos ovinos. Embora a matéria seca disponível da Caatinga raleada e enriquecida com capim buffel apresentasse baixos teores de proteína bruta e de digestibilidade in vitro da matéria seca, os caprinos conseguiram selecionar uma dieta capaz de permitir um consumo superior a 2% do peso vivo. The objective of this word was to evaluate the chemical composition, digestibility and intake of herbaceous vegetation in a thinned and enriched with buffel grass (Cenchrus ciliaris L.) Caatinga grazed by sheeps and goats. 12 goats F1 (Boer x SRD) and 12 Santa Inês sheeps with live weight of 15,00kg were used. The vegetation data were analyzed using a completely randomized design with repeated observations over time, and the animals intake of was also a completely randomized design with two treatments and twelve repetitions. Grazing did not affect the chemical composition and in vitro digestibility of herbaceous vegetation. On the evaluation on june 1st the three floristic components had the lowest percentage of dry matter and the higherest percentages of crude protein and in vitro digestibility of dry matter, while the opposite occurred in august 1st, differing even from that observed in september 1st and october 1st. The goats intake was 437.47 of dry matter, compared to 331.78g of dry matter intake by sheep. Although the available dry matter from thinned and enriched caatinga with buffel grass presented low levels of crude protein and in vitro digestibility of dry matter, the goats were able to select a diet that allowed intake

Abstract: O experimento foi conduzido na Universidade Federal de Campina Grande (UFCG), Patos, Paraíba, Brasil com o objetivo de avaliar a procura de água e sombra por caprinos F1 Boer x SRD terminados em pastagem nativa e submetidos à suplementa o. Utilizou-se 28 caprinos n o castrados, com 120 dias de idade e peso vivo inicial de 15,52kg, distribuídos em quatro níveis de suplementa o (0,0; 0,5; 1,0 e 1,5% do peso vivo em MS), com sete repeti es. Os avaliadores passaram por treinamento para aprimorar a metodologia e para adapta o dos animais às suas presen as. Os dados foram obtidos através da observa o da frequência de procura de água e sombra pelos animais durante o pastejo diário em três épocas: junho, julho e agosto. N o houve diferen a entre tratamentos para procura por água e a frequência observada foi de 71,43; 80,95; 88,89 e 77,78% para os tratamentos 0,0; 0,5; 1,0 e 1,5% de suplementa o, respectivamente. N o houve efeito dos tratamentos na procura por sombra e a frequência observada foi de 71,43; 85,71; 94,44 e 94,44% nos tratamentos 0,0; 0,5; 1,0 e 1,5% de suplementa o respectivamente. A suplementa o n o altera a frequência de procura de água por caprinos F1 Boer x SRD terminados em pastagem nativa. Os níveis de suplementa o e as épocas n o influenciaram a procura de sombra. The experiment was carried out at the Federal University of Campina Grande (UFCG), Patos, Paraiba, Brazil. The objective of this study was to evaluate the search for water and shade by Boer goats crossbreeds finished in native pasture under different supplementation levels. Twenty-eight Boer goats crossbreeds, non castrated, with 120 days old and an initial live body weight of 15.52Kg, were used. The treatments were randomly assigned to the animals according to a completely randomized design, with 4 feeding supplementations levels (0.0; 0.5; 1.0 and 1.5% of live body weight on Dry matter) and seven replications (goats). Data were obtained through the observation of the search frequency for water and shade by the animals during the daily grazing in three times: June, July and August. There wasn’t difference among treatments for search for water and the frequency observed was of 71.43, 80.95, 88.89 and 77.78% for the treatments 0.0; 0.5; 1.0 and 1.5% of feeding supplementation, respectively. There wasn’t effect of the treatments in the search for shade and the frequency observed was of 71.43, 85.71, 94.44 and 94.44% in the treatments 0.0; 0.5; 1.0 and 1.5% of feeding supplementation, respectively. The feeding supplementation level doesn't alter the search frequency of water

Abstract: O experimento foi conduzido com o objetivo de avaliar o efeito do tratamento com hidróxido de sódio (NaOH) na fra o fibrosa, no teor de tanino e na digestibilidade in vitro da matéria seca do feno de jurema-preta. As folhas foram colhidas manualmente e desidratadas à sombra. O tratamento químico consistiu na pulveriza o do feno com solu o de 0; 2; 4; 6 e 8% de NaOH, na propor o de 1 litro da solu o para 1 kg de feno. Amostras do feno foram submetidas à determina o da matéria seca (MS), proteína bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), tanino e digestibilidade in vitro da matéria seca (DIVMS), que se constituíram nas variáveis analisadas. O delineamento foi o inteiramente casualizado, com cinco tratamentos e quatro repeti es. O tratamento com NaOH proporcionou efeito linear decrescente nos teores de MS, hemicelulose e tanino, enquanto, para FDN e FDA, ocorreu efeito quadrático. A PB n o foi afetada e a DIVMS melhorou com o aumento da concentra o de NaOH. A estimativa da DIVMS pelo teor de tanino, apesar de significativa, carece de mais estudos.
