“…This decline in NDF content could be related to the increasing proportion of leaf compared to stem of urea treated grass. Similar phenomenon was also found in previous studies [11,12] in which NDF content of grass declined due to N fertilisation.…”

“…The response of P. atratum to the level of urea fertilisation is presented in Table In the meantime, plant additionally utilized accessible nitrogen to synthesise its tissue, so the plant height was likewise expanded in light of increased level of urea preparation. Increasing DM yield of grass in response to the increasing nitrogen fertiliser is in agreement with previous findings [7][8][9][10][11][12]. Havlin et al [13] noticed that nitrogen application can stimulate the number and wide of leaf which can enhance the vegetative growth components, such as the plant height and the number of tiller, due to stimulation of photosynthesis process of the plants.…”

Two trials were carried out to evaluate the response new introduced grass Paspalum atratum with different management in Central Sulawesi, Indonesia. The first trial was done to examine the effects of levels of urea fertilization on growth, biomass production and nutritive value of P. atratum. A 4 × 8 completely randomized block design was employed in this study. The treatment imposed was four levels of urea fertilization namely 0, 100, 200 and 300 kg/ha. All treatments were repeated eight times. The runners of tillers of P. atratum were planted at separation of 75 cm × 75 cm in each 3 m × 3 m plot. Parameters such as plant hight, tiller number, leaf width and nutritive value of P. atratum were measured at Days 28 and 56 after first cut. The second trial was conducted to study the effect of P. atratum, legume herbs mixture on growth and yield of P. atratum. A completely randomized block was designed with four treatments, eight replicates, with 32 total plots. Each plot comprised of 3 m × 3 m. The treatments tested in this study include P. atratum planted as monoculture (P), P mixed with Dolichos lablab (PDL), P mixed with Centrosema pascuorum (PCP) and P mixed with Clitoria ternatea (PCT). Parameters recorded include plant height, tillage number, leaf width and biomass dry matter (DM) production of P. atratum. The results of trial one demonstrated that levels of urea fertilisation significantly (p < 0.05) increased plant height, tillage number, DM production and crude protein (CP) content, and reduced significantly neutral detergent fibre (NDF) of P. atratum. No significant effect (p > 0.05) was detected of the level of urea fertilastion on leaf width, DM, organic matter (OM) and ether extract (EE) of P. atratum. Experiment two, exhibited that mix planting between P. atratum with legume herbs did not affect significantly (p > 0.05) plant height, tillage number, leaf width and biomass DM production of P. atratum.

“…Isobutyrate and isovalerate levels significantly increased with increasing proportions of WCWH, which were due to the increased metabolism caused by the WCWH diets 39 . Consistent with our report, branched-chain VFAs (BCVFAs) are particularly required by most fibre-degrading bacteria and can increase fibre degradation 40 .…”

Twelve Holstein bulls were used in a 4 × 4 Latin square design to investigate the effects of using whole-crop wheat hay (WCWH) as a substitute for Leymus chinensis (LC) on apparent digestibility, plasma parameters, ruminal fermentation, and microbial communities. Experimental treatments were four proportions of WCWH, 0, 33, 67, and 100%, as a substitute for LC (WCWH0, WCWH33, WCWH67, and WCWH100, respectively). The WCWH100 group showed a higher nutritional intake of crude protein (CP) and higher apparent digestibility of organic matter (OM), CP, and ether extract (EE) than the WCWH0 group (P < 0.05). Urea N, NH3-N, isobutyrate and isovalerate levels were higher (P < 0.05) in the WCWH100 group than in the WCWH0 group. 16S rRNA high-throughput sequencing analysis revealed similarities in the community composition, species diversity and relative abundance of dominant bacteria at the phylum and genus levels among the four groups. Collectively, our data indicated that WCWH can be used to replace LC in the diet of finishing dairy bulls without having a negative impact on apparent digestibility, plasma parameters, and ruminal bacteria composition. These results offer the first deep insight into the effects of replacing LC with WCWH on the performance parameters and rumen microbiota in Holstein bulls, and may aid in ruminant farming.

“…In tropical forage grasses, Bezabih et al [13] discovered a link between forage chemical composition and in vitro fermentation parameters. In contrast, nitrogen (N) fertilization improved biomass yield, crude protein, cellulose, and lignin content by decreasing the energy content available for metabolism and slowing the fermentation rate as well as decreasing in vitro dry matter disappearance and cumulative gas production [14].…”

Integrating farmyard manure (FYM) and legume intercropping improves soil chemical and microbial properties, thereby increasing forage productivity and nutritional value. The purpose of this study was to evaluate how fertilizer treatments affected the chemical composition, in vitro gas production and organic matter digestibility (IVOMD), and volatile fatty acid production (VFA) of Napier and desho grasses in the upper Blue Nile basin of Ethiopia. Apart from ether extract content, the chemical composition of the fertilizer treatments in the Aba Gerima watershed did not differ significantly, whereas significant differences were observed in acid detergent fiber and crude protein contents at the Guder watershed. In both watersheds, Napier grass had significantly higher crude protein levels than desho grass. In Aba Gerima, ash content was significantly higher in 2018 than in 2019, but not in Guder. For Napier and desho grasses, there were an increment in IVOMD (6.7 vs 4.7%), metabolizable energy (5.5 vs 4.5%), and VFA production (23.1 vs 3.0%) in the Desmodium intortum plus FYM treatment than in the control in Aba Gerima. In Guder, however, IVOMD (13.7 vs 4.6%), metabolizable energy (13.3 vs 3.3%), and VFA production (11.2 vs 5.6%) increased in the same treatment for Napier and desho grasses than in the control. This study suggests that the Desmodium intortum plus FYM improves the nutritional value, IVOMD, and VFA production of Napier and desho grasses in dryland areas of the upper Blue Nile basin, facilitating their growth as alternative livestock feed for better production in these areas.
