“…Based on the data recorded during the experimental period (92 days) the feed intake of silage DM was higher by 6.5% for treated silage than that of the untreated silage, corresponding to the results from [59]. The intake of compound feed did not differ as it was restricted to a certain amount for both treatments.…”

“…Protein N was determined by subtracting trichloroacetic acid soluble N from total N according to the method of Kuchroo and Fox (1982). Total amino acids were extracted and analysed as described by Winters et al (2001).…”

“…In addition, high buffering capacity, a consequence of a high protein content (Muck et al, 1991) and low water-soluble sugar content, make this crop difficult to ensile (McDonald et al, 1991). Poor fermentation is associated with increased protein degradation during ensilage (McDonald et al, 1991;Winters et al, 2000;Winters et al, 2001) which tends to decrease efficiency of N utilisation by ruminants (Charmley, 2001(Charmley, , 2002.…”

White clover nitrogen N content is generally high and constant throughout the growing season. It is also difficult to manipulate, as N 2 fixation tends to maintain a high N supply to the plant. White clover is a highly heterozygous, natural out-breeder, but self-fertile lines have recently been developed, including one which fails to develop nodules when grown under appropriate physiological conditions. An advantage of this line is that leaf protein content can be manipulated by altering the N supply to the plant and, in addition, it offers the opportunity to examine the effect of protein content on silage quality. This line was grown under varying levels of nitrate-N, giving rise to plants with a range of protein contents which were subsequently conserved as silage in two separate experiments. In experiment 1, both herbage protein and water-soluble carbohydrate (WSC) content varied, with values ranging from 17 to 31 g/kg dry matter (DM) and 52 to 72 g/kg DM, respectively. Protein content also varied in herbage grown for experiment 2, ranging from 20 to 33 g/kg DM, but variation in WSC content (91-101 g/kg DM) was not statistically significant. Silage quality was dependent on the protein content of the fresh herbage in both experiments. A comparison of herbages with high and low initial protein content, from experiments 1 and 2, respectively, revealed that a high protein content resulted in silages with a higher pH .L. Winters et al. / Animal Feed Science and Technology 116 (2004) 319-331 versus 659 g/kg TN), and an increase in free amino acid content when expressed as a proportion of total N (267 g/kg versus 90 g/kg and 323 g/kg versus 200 g/kg TN). A higher initial protein content results in a higher proportion of protein degradation during ensiling.

“…Active development of these bacteria promoted considerable accumulation of lactic acid in plant mass and preservation of nutrients in forage. According to published results the microbial proteolysis of the green crops is limited, though lactic fermentation indirectly stimulated clover protein hydrolysis by endogenous proteases (Winters et al, 2000;Winters et al, 2001). Therefore, the introduced strain of L. RS4 gives an additional possibility for digestion of partially hydrolyzed proteins by its own proteases and increases the availability of silo proteins as well as the level of essential amino acids for feeding of animals.…”

Biological preservative on the basis of native strain of lactic acid bacterium Lactobacillus RS4, isolated from epiphytic microflora of clover, is recommended for practical application by preparation of forages from the high-protein dried crops. The comparative analysis of chemical composition, organic acids, amino acids and nutritional value of the main forage crops, and also characteristic parameters of three options of silages of clover revealed that the introduction of lactobacilli in plant biomass is economically effective.
