Consumo hídrico da rúcula em cultivo hidropônico NFT utilizando Rejeitos de dessalinizador em Ibimirim-PE

O consumo de águas salinas pelas plantas na maioria dos casos afetam o rendimento das culturas em suas diversas fases prejudicando desenvolvimento e produção. O trabalho avaliou o consumo hídrico da rúcula (Eruca sativa) em sistema hidropônico NFT com águas salinas. Foram analisados seis níveis crescentes de salinidade da água (CEa), quais sejam: 0,2; 1,2; 2,2; 3,2; 4,2 e 5,2 (dS m-1) utilizaram-se duas fontes de sais: águas salobras (AS) e NaCl. Foi determinado o volume evapotranspirado por planta (VETc) no sistema durante o cultivo. O consumo hídrico nos primeiros dias após transplantio foi de 250 mL dia-1 aproximadamente para ambas as testemunhas e decresceram com o aumento da salinidade, a eficiência de utilização da água foi reduzida revelando uma resposta linear decrescente em função da salinidade ocorrendo uma resposta negativa das plantas que apresentaram uma redução na quantidade de folhas de 3,34%.

Consumo, digestibilidade aparente de nutrientes e balanços de nitrogênio e hídrico de ovinos alimentados com silagens de cultivares de capim-búfel

The objective of this present experiment was to determine intake and apparent digestibility of dry matter and nutrients, nitrogen (NB) and water balances (WB) of sheep fed with buffel grass silages. The buffel grass cultivars used were Tanzania, Buchuma and Biloela. 21 male, castrated, crossbred Santa Ines x Non defined genotype sheep, with initial body weight of 31.8±3.16kg were used, kept in metabolic cages. The experimental design was completely randomized with seven replicates. No differences were observed in dry matter intake in g/day (919.2) and % of body weight (2.9). In general, digestibility coefficients of dry matter varied from 37.7% to 60.0%. The NB and WB were positive, with higher NB values in sheep fed with Tanzania (5.1g/day) and Biloela (3.9g/day) and higher WB in animals fed with Buchuma (1.38kg/animal/day) and Biloela (1.42kg/animal/day). All cultivars of buffel grass evaluated (Tanzania, Buchuma and Biloela) presented adequate chemical composition, where the silage of buffel grass used corresponded to 60% of the total daily water intake by sheep.

Consumo e digestibilidade aparente dos nutrientes em ovinos alimentados com dietas contendo diferentes quantidades de farelo de linhaça

The aim of this research was to evaluate the intake and apparent digestibility of nutrients in sheep fed with diets containing different amounts of linseed meal. The treatments evaluated were: corn silage exclusive (control); corn silage + concentrate; corn silage + concentrate + 5% of linseed meal; corn silage + concentrate + 10% of linseed meal. The dry matter (DM) intake has increased in diets containing concentrated if compared to diet exclusively with corn silage (P<0.05), however, there was no effect of the inclusion of linseed meal in diets (0; 5 and 10%). As it was expected, the diets containing 5 and 10% of linseed meal resulted in an increase of ether extract (EE) intake. A higher apparent digestibility of DM, organic matter (OM) and neutral detergent fiber (NDF) in the animals fed with diets containing the concentrate was observed, independently of linseed meal proportion. According to the experimental conditions under which the experiment was developed, itis recommended to provide the diets containing until 5% of linseed meal, because there is no negative effect on dry matter and nutrients intake, as well as on apparent digestibility.
