The nutritive values for ruminants of cauliflower (CAU) and Romanesco (ROM) wastes (leaves, stems sprouts) were assessed by analyzing their chemical composition, in vitro ruminal fermentation, intestinal digestibility. In addition, the fermentation diets containing increasing amounts CAU was studied. dry matter (DM) content leaves, sprouts both vegetables lower than 10%, but they contained high crude protein (CP; 19.9 to 33.0%) sugar (16.3 28.7%) levels, low neutral detergent fiber (21.6...

Almond hulls (AH) are frequently used in dairy ruminant feeding, but information on variability of their nutritive value and potential effects CH4 production is still scarce. The influence almond variety (Guara vs. Soleta) chemical composition energy AH was investigated using 10 samples per collected 2 consecutive years. Guara-AH had greater (p ≤ 0.015) ash, protein, fat content, lower 0.001) fiber than Soleta-AH. metabolizable content estimated from vitro gas 8.5% for Guara Soleta samples....

Abstract Ruminants have a low efficiency of nitrogen (N) utilization that has negative implications for animal production and the environment, but reducing ruminal degradation protein can help to reduce N losses. The objective this study was evaluate inclusion sunflower meal ( SM ) seed SS protected against in high‐cereal diets on vitro fermentation CH 4 production. Samples were sprayed with solution malic acid 1 M (400 ml/kg sample) dried at 150°C hr as protective treatment. Four formulated...

Typha is a wild plant with invasive growth that causes environmental problems in different areas worldwide. This study investigated the ensiling potential of typha (Typha latifolia) to be preserved and used for ruminant feeding. Four silage treatments were evaluated: no additives (CON); formic acid (FA; 4 mL/kg); urea molasses (UM; 19 24 g/kg, respectively); acid, urea, (FAUM; all at previous concentrations). Three bags each prepared stored months before being analysed fermented vitro...

Abstract Olive oil extraction generates olive cake (OC) that could be used in ruminant feeding. However, the chemical composition of OC is affected by multiple factors, being therefore highly variable. The objective this study was to analyse influence storage time and further processing: crude, exhausted (subjected a second extraction) cyclone (obtained from separator) on nutritive value samples. Twelve samples (six crude six exhausted) were obtained monthly same pond 1 6 months, nine (three...

The effects of treating sunflower seed (SS) and meal (SM), as well a mixture both feeds (SSM; 45:55) with solution malic acid (1 M; 400 ml/kg feed) heating for protection against ruminal degradation were studied. Four rumen-fistulated sheep fed two mixed diets composed oat hay concentrate (40:60) differing only in the concentrate, that contained either untreated SS SM (control diet) or treated (MAH diet). A crossover design 24-d experimental periods was used, each period included 10 d diet...

Seaweeds could be alternative feedstuffs for ruminants, but their utilization in practical feeding is difficult because they deteriorate rapidly. We investigated the possibility of preserving Saccharina latissima and Porphyra umbilicalis multinutrient blocks (MB), which a cost-effective preservation method high-moisture feeds. Three different MB were prepared: without seaweed (control; CMB), with 25% fresh S. (SLMB), 36% P. (PUMB). Both seaweeds fermented vitro ruminal fluid from sheep. The...
