This study was performed to investigate how to smoke solution affects dry matter loss, crude protein (CP) and toxic compound ODAP contents of grass pea in hydroponic media during seven days period. Three doses of smoke solutions (1, 5 and 10%, V: V) by diluting with tap water were applied to seeds as priming agent, and tap water was used as a control (0%). The experiment was arranged according to the split-plot design with three replications. Compared to seed, significant change was detected in hydroponic sprouts depending on the day in terms of dry matter loss and chemical content. Grass pea sprouts had higher CP and lower ODAP content than seed, even in control treatment. Furthermore, smoke solution increased the efficiency of system by increase CP, decrease ODAP content and also decreases dry matter loss, with significant effect on doses. CP of sprouts increased day by day and was the highest on day 6 (36.27%) at the 10% dose of smoke solution followed by 5% on day 7 (36.09%). ODAP decreased up to day 6 and then began to increase, but it was lower than control at all doses of solution during to experiment. This study showed that grass pea is suitable crop for hydroponic forage produce and that smoke solution can make a significant contribution to yield and quality of sprouts, especially at the dose of 10%. However, when the yield, nutritional value, and safe use were evaluated together, it was observed that the best time for harvesting was the end of the 6th day and delaying did not provide a significant advantage and even occurred undesirable results in terms of ODAP and dry matter. more...

This study explores the use of an electronic nose (E-nose), equipped with ten metal oxide semiconductor thin-film sensors, to detect raw milk samples from buffaloes fed hydroponic barley forage as a substitute for maize silage. 108 samples were collected on three different days, from three groups of twelve Italian Mediterranean buffaloes each. The control group (C) was fed a diet based on maize silage, which in the other groups was replaced by hydroponic forage at 50 % (LH group) and 100 % (HH group). The data pattern from the E-nose sensor responses data was analysed using linear discriminant analysis (LDA) and principal component analysis (PCA) as pattern recognition methods, to investigate the discrimination capability of the sensor array. Confusion matrix, obtained from LDA, correctly classified C, LH and HH milk at 90 %. Solid-phase microextraction with gas chromatography–mass spectrometry revealed that C samples had the highest total level of volatile organic compounds, particularly ketones, volatile fatty acids and esters, while HH had the lowest quantity of volatile fatty acids and higher amounts of p -cresol, 1-octen-3-ol and dimethyl sulfone. This has resulted in a greater response intensity of most E-nose sensors for C, such as W1S, W2S, W3S and W6S, which react to high concentrations of broad-range and aliphatic compounds. E-nose proves effective in rapidly identifying hydroponic forage in buffalo diets.

Objective: Determine the apparent digestibility (AD) of diets with hydroponic maize green fodder (HMGF) (Zea mays L.) and evaluate its effect on dry matter (DM) intake and daily weight gain (DWG) in lambs. Design/methodology/approach: Two experiments were carried out with four inclusion levels of HMGF (0, 20, 40, 60% of DM) in the diet. A total of 16 sheep was used to determine the AD of the diet. Growth testing was carried out in 20 male lambs. Both studies employed a completely randomized design. Results: The AD of DM and crude protein was higher in diets with 40 and 60% of HMGF (P≤0.05; P ≤0.01). Lambs fed diets with 0 and 20% of HMGF showed higher DWG (P ≤ 0.05). Sheep fed diets with 60% of HMGF showed lower DM intake (P≤0.05). Study limitations/implications: Although there are currently several methods to supplement sheep during drought periods, few are fully adapted to what the producers need. Hydroponic maize green fodder is a valuable alternative for the rapid and constant production of high nutritional value fodder. Findings/conclusions: The hydroponic maize green fodder has high digestibility, and thus, it can be used as an excellent source of fodder in the diet of lambs, obtaining adequate weight gains with rations that include up to 40% in the ration in substitution of commercial feed.

The objective of this study was to evaluate the productivity and protein content of forage of hydroponic maize cultivated on sugar cane bagasse, and identifying the appropriate amount of seeds, the ideal harvest date and the possibility of using vinasse as nutritive solution. The experiment was carried out under greenhouse conditions, in a factorial 5x2x2 scheme. Corn seeding densities were 0.5, 1.0, 1.5, 2.0 and 2.5 kg m-2. Two nutritive solutions were used (6 L m-2 day-1), one as described by FAO and another as diluted vinasse. Harvests were done at 10 and 20 days after sowing. Fenologic measurements were carried out, as well as fresh and dry matter weight and crude protein contents were determined. On average, 1.0 to 2.5 kg m-2 of maize resulted in 11.88% crude protein, differently of the 0.5 kg m-2 density, that resulted in a significantly lower content. Using vinasse and harvest at 20 days, 2.0 kg seeds m-2 are sufficient to result in maximum fresh matter production. However, greatest dry matter weight were obtained using 2.5 and 2.0 kg m-2 seed at 10 and 20 days after sowing, respectively. more...
