“…Another factor to be taken into consideration is that the addition of dehydrated barley increased the dry matter, and by this likely favoured better fermentation of ensiled material and thus reduce the losses caused by effluent formation. These results were similar to those of Ribeiro et al (2008), who observed FVI values of 76 and 141 in a study of Tanzania grass silage with levels of 0, 8, 16, 24 and 34% wheat bran.…”

“…A similar behaviour was observed for the consumption expressed in relation to metabolic weight. Ribeiro et al (2008) estimated dry matter intaketo vary between 1.74 and 2.59% live weight for Tanzania grass silages on increase of 0 to 30% wheat bran. The initial increase in dry dry matter intake in the present study can be explained in part by the increase in dry matter content of the silage.…”

Intake and digestibility in sheep fed on marandu grass silages added with dehydrated barley

et al. 2017

The objective was to evaluate the intake and the apparent digestibility in sheep fed on marandu grass silages added with dehydrated barley. Twenty crossbred Santa Inês lambs were used, with a mean initial weight of 30±4.5 kg and mean age of 14±2 months. The experimental sheep were distributed into a completely randomized design and lining, with five treatments and four repetitions, with treatments levels of inclusion of 0, 10, 20, 30 and 40% natural matter of naturally dehydrated brewery residue for 36 hours to the marandu grass silage to feed the sheep. The evaluation period lasted 21 days, 15 for adaptation to the diets and 7 days for data collection. The data was submitted to analysis of variance, and when significant (P<0.05) the treatment means were analysed by regression. The inclusion of dehydrated barley to silage showed a linear increase in water intake (P<0.05), increased by 0.02% per unit of dehydrated barley. A quadratic effect was observed for the levels of dehydrated barley on the dry matter intake (DM), estimating a maximum consumption of 2.86% DM for silages containing 17.8% dehydrated barley. The crude protein intake (CP) behaved quadratically, with the maximum value estimated of 0.29% CP at a level of 22.5% dehydrated barley. Ether extract (EE) intake also exhibited quadratic behaviour (P<0.05), with the maximum value estimated of 0.2% EE at a level of 28.25% dehydrated barley. The regression study showed quadratic behaviour; with the maximum estimated value of neutral detergent fibre was 2.33% at a level of 34.58% dehydrated barley. No statistical significance was found for the intake of acid detergent fibre or organic matter (P>0.05). It was concluded that the addition of levels of 20 to 30% of dehydrated barley to silage resulted in a positive response for the dry matter intake, crude protein, Ether extract and neutral detergent fibre.

“…Based on the literature for tropical grasses, the DM content ranges from 157.8 to 280 g/kg (Patrizi et al, 2004;Ribeiro et al, 2008;Ávila et al, 2009;Silva et al, 2011). According to McDonald et al (1991), the optimum dry matter content for good quality silages ranges from 300 to 350 g/kg.…”

“…Regarding the increase in the CHO contents with greater cutting heights, these values are considered to be low and characteristic of tropical grasses (Ribeiro et al, 2008;Ávila et al, 2009;Vasconcelos et al, 2009). However, the mean level of silage CHO was 7.2 g/kg, regardless of cutting height.…”

Microbial and fermentation profiles, losses and chemical composition of silages of buffel grass harvested at different cutting heights

et al. 2013

-The present study evaluated the microbial population, fermentation profile, losses and dry matter recovery, and chemical composition of silages of buffel grass at different cutting heights. To evaluate the microbial fermentation dynamics, the treatments resulted from a 4 × 5 factorial combination consisting of 4 cutting heights and 5 fermentation periods, in a completely randomized design with three replications. The fermentation was evaluated at the end of 1, 3, 7, 15 and 30 days. The other characteristics of silages with 30 days were evaluated following a completely randomized design with four treatments, consisting of 4 cutting heights (30, 40, 50 and 60 cm), and five replications. Fermentation period and cutting height effects and interaction between both factors were observed on the populations of lactic acid bacteria (LAB), enterobacteria and molds and yeasts. The peak of development of LAB populations was observed on the seventh day of fermentation for the heights of 40 and 50 cm, with 8.25 and 8.30 log cfu/g, respectively. The pH values of silages ranged with different cutting heights, in which at the height of 50 cm the decrease was most pronounced. However, the pH values were similar between the cutting heights at the end of 30 days of fermentation. Quadratic relationship was observed between lactic acid concentrations and cutting heights. The crude protein content behaved linearly, initially showing 128.5 g/kg DM at 30 cm, decreasing as the cutting heights increased. The neutral detergent fiber and ether extract contents increased linearly with the cutting heights. Based on microbial populations, fermentation, losses and chemical composition, it is recommended to harvest buffel grass for silage from 50 cm on.
