We hypothesized that Moringa oleifera foliage which is high in crude protein and almost free in main secondary compounds could replace soyabean meal used in supplementation strategies of livestock. Therefore, this experiment aimed to evaluate the effect of daily and alternate day supplementation of Moringa leaf meal (MLM) or soybean meal (SBM) to sheep on intake and digestion and glucose, protein and urea in blood plasma. Twenty Barbarine male lambs (average initial body weight, 27.373.0 kg), were randomly divided into four groups of five lambs each. They were adapted for 22 days to dietary treatments before starting a 6-day total collection period. All animals consumed oat hay ad libitum supplemented with concentrates composed of barley grain only (C-BAR) or mixed with SBM (C-SBM), or MLM (C-MLM) as protein sources. Groups 1 and 2 received daily C-SBM and C-MLM, respectively. However, groups 3 and 4 had access to concentrates containing the protein sources (C-SBM and C-MLM) with alternate day that means they received for one day these concentrates and in the following day they received barley grain only (C-BAR). Soybean meal and MLM incorporation in concentrates had similar effects (P40.05) on water, hay, and digestible organic matter (OM) intakes and DM, organic matter (OM) and neutral detergent fiber (NDF) digestibility. Daily substitution of SBM by MLM increased (P¼0.024) crude protein (CP) intake and apparent total tract digestibility. However, the alternate day supplementation decreased apparent total tract CP digestibility but increased CP intake for SBM treatment. The concentration of ruminal ammonia nitrogen before feeding was higher (P¼ 0.012) in groups 1 and 3 than in the other groups. The concentration of blood glucose was similar (P40.05) among treatments. However, lambs receiving C-SBM exhibited highest concentrations of protein (P¼ 0.039) and urea (P¼ 0.001) in the blood. It is concluded that MLM administered at two day-intervals had similar effects on feed intake, digestion and blood metabolites to SBM incorporated in concentrate distributed to sheep receiving oat hay.

The main objective of this study was to highlight the fertilizing capacity of the extract of ovine compost (prepared to the simple infusion) in gardening nursery, while specifying the appropriate ratios of extraction and dilution ,for soilless plant fertigation intended for two strategic summer crops in Tunisia: seasonal tomato and seasonal pepper. It is clear that such extraction ratio of 1: 5 is effective for plants fertigation of two considered species. In addition, it has been shown that 200 times dilution of the concentrated extract is beneficial for the growth of tomato plants. However, this organic liquid fertilizer with different dilutions applied and in the experimental conditions adopted, wasn't moderately efficient in stimulating the growth of pepper plants. The importance of this type of compost produced from sheep biomass, widely available in Tunisia, encourage the diversification of its exploitation, which is the object of this preliminary work, deserving more future investigations.
