Chemical treatment of roughage has been the aim of studies for a long time. However, until nowadays, many questions are arisen due to the efficiency of additives used in relation to the variation of answers, either in nutritive value of treated roughage or in performance of animals feed with diet containing such roughage. This revision will approach the main and most used products, which are anhydrous ammonia, urea, sodium hydroxide and calcium oxide. It has been noticed that ammonization (both […]

The objective of this trial was to evaluate chemical and bacterial additives on inhibition of ethanol production, reduction of DM losses and on in vitro digestibility improvement of sugar cane silages. Treatments were (wet basis): without additive – control; urea – UR – (0.5; 1.0; 1.5%), NaOH (1; 2; 3%), calcium propionate – PROP – (0.05; 0.1; 0.2%), sodium benzoate – BENZ – (0.05; 0.1; 0.2%), potassium sorbate – SORB – (0.015; 0.03; 0.045%), Lactobacillus plantarum – PLA – (1 […]

In order to increase the sugar cane bagasse digestibility, this agricultural by-product was treated with several chemical reagents with or without physical treatment. After preliminary evaluation, where several delignificant agents were evaluated, ten treatments were selected for more detailed in vitro dry and organic matter disappearance trials. Then, for the in vivo digestibility trial, four sugar cane bagasse based diets were made: 1 – Hydrolyzed sugar cane bagasse, pressure of 17 kgf/cm2 per 5 min; 2 – Bagasse treated with […]
