Silage Quality

 The effect of adding an inoculant containing Lactobacillus buchneri, L. plantarum and L. casei to wilted perennial ryegrass, harvested at four growth stages and ensiled for either 60 or 150 d on silage fermentation quality, chemical composition, rumen degradability of neutral detergent fibre (NDF) and organic matter (OM) and in vitro OM digestibility (OMd) was studied. Compared to the control silage, more sugars were fermented to lactic and acetic acid with the inoculant, resulting in a lower pH, less dry matter losses and protein degradation and a better aerobic stability. The effects of the additive on fermentation quality were more pronounced after 150 than after 60 d of ensiling, because the quality of the control silage was worse after long ensiling period. The treatment lowered NDF content of grass harvested at the first two growth stages by degrading cell walls to complex sugars, but had no effect on NDF degradability of the silage. The inoculant had no effect on rumen OM degradability nor on OMd after the short ensiling period, but increased the rumen OM degradability for the first two growth stages and OMd for all growth stages after long ensiling period.

Whole-crop wheat (WCW) is rich in nutrients and is widely used as a forage crop. This study consisted of 2 experiments: Experiment 1 studied the yield, nutritive value and silage quality of WCW at 3 seeding rates (320 kg/ha, S320; 385 kg/ha, S385; and 450 kg/ha, S450) and different fertilizing times, i.e. 60% at seedling stage and the remaining 40% at the jointing stage vs. heading stage; and Experiment 2 examined the yield, nutritive value and silage quality of WCW receiving different fertilizer types, i.e. urea, compound fertilizer (N:P:K) and urea + compound fertilizer (all iso-nitrogenous). With the increased seeding rate, dry matter (DM) and crude protein (CP) yields tended to increase, but relative feed value tended to decrease. Experiment 1: there was no significant interaction between time of applying the second fertilizer dose and seeding rate in terms of concentrations of CP, crude fiber, ether extract, crude ash, nitrogen-free extract, neutral detergent fiber (NDF) and acid detergent fiber (ADF) in wheat (P>0.05). However, a significant interaction between fertilizing time and seeding rate was observed in terms of silage fermentation quality (pH, lactic acid, butyric acid and NH3-N concentrations) (P<0.05). Experiment 2: DM yield, CP yield and concentrations of CP, ADF and water-soluble carbohydrate were not affected by fertilizer type (P>0.05). Fertilizer type had significant effects on pH of silage and concentrations of organic acids (except propionic acid) and NH3-N in WCW silage (P<0.05). Under the present study conditions, considering DM yield, nutrient composition and silage fermentation quality, an optimal seeding rate of wheat for forage appears to be about 385 kg/ha. N fertilizer should be applied at the seedling stage and jointing stage. Although applying a mixture of urea and compound fertilizer had no significant effects on yield and nutritive value of WCW relative to applying urea alone, it did improve silage fermentation quality. Results may differ on different soils.

The purpose of this study was to determine the phenological development and the nutritional quality of Sorghum almun during different growth stages. The seed was cultivated in the Alfredo Volio Mata Experimental Station of the University of Costa Rica. Eighteen kg of 88% germinal seed per hectare were planted. The first sample was taken 24 days after sprouting and every 14 days thereafter, up to 150 days. The production of biomass of the stems, leaves and ears of grain were measured and the amounts (content) of dry mater matter, crude protein, total ashes, neutral fiber and detergent acid, hemicellulosa, cellulose and lignin were determined. During the first 52 days of growth, the output of leaves was higher than that of stems. On the 57th day, a yield of 1395 kg of dry matter per hectare, 50% leaves and 50% stems, was estimated. The ears of grain appeared after 94 days, contributing 50kg per hectare of dry matter. The concentration of dry matter in the leaves was highest from the moment of sprouting to the 136th day. The content of crude protein in the leaves was always superior to that in the stems. In the leaves the crude protein diminished 16%-28% between the 38th and 150th day of growth. In the same period, the crude protein in the stem diminished 5%-18%, and in the whole plant 8%-26%. The neutral fiber and detergent acid in the leaves and the stems were less than 60% during the first two months of growth and more than 70% in the latter period.
