“…There was an increase in crude protein (CP) content (p<0.05) with increasing doses of urea, due to the incorporation of non-protein nitrogen (NPN) in the roughage (Pires et al 2010), with an increase of 9.7% in the treatment with the highest dose of urea. Similar effects were obtained by Garcez et al (2014) showing an increase of 13.7% in CP when treating babassu pindoba hay with 4 or 6% urea, and Oliveira et al (2011) and Carvalho et al (2006), when treating sugarcane bagasse with up to 6% and 7.5% urea, respectively, roughages with chemical composition similar to the sugarcane tip hay used in this research.…”

The present study aimed to evaluate the effect of alkaline treatments with urea, NaOH and Ca(OH) 2 on chemical composition and in situ ruminal degradability of dry matter, crud protein and neutral detergent fi ber of sugarcane tip hay. Samples were incubated in the rumen of three cannulated cattle for up to 72 hours in a split plot randomized block design. Ammoniation with 6% urea increased (p<0.05) the crude protein content by 13% and reduced the neutral detergent fi ber and insoluble nitrogen content of the hay. When treated with the highest doses of the compounds, there was a high potential degradability of dry matter, crude protein and neutral detergent fi ber, and a shorter neutral detergent fi ber lag time. Ammoniation with urea promotes a reduction in the content of NDF, hemicellulose and insoluble nitrogen, with an increase in the content of CP in the hay, with emphasis for the level of 6% urea. The ruminal degradation of sugarcane tip hay increases with alkaline treatments using 6% urea or 3% NaOH, however, ammoniation with urea is indicated for the treatment of hay, as this is low cost and can be easily adopted by farmers in the semiarid region.

The objective of this study was to evaluate in situ ruminal degradability of elephant grass silages with addition of 8, 16 and 24% of faveira pods in experimental silos of 100x50 mm, equipped with bunsen valves. The content of crude protein (cp) and neutral detergent fiber (ndf) were determined on a dry matter basis. To evaluate the in situ degradability of dm, cp and ndf, nylon bags containing 4 g sample were incubated in the rumen of three fistulated cattle for 6, 24 and 72h. The dm and cp content of elephant grass silages increased (p < 0.05) from 8% inclusion associated with a higher concentration of constituents in faveira pods (77.25 and 9.61% dm). The ndf fraction reduced 10.91% (p < 0.05) when adding 24% pods. The potential degradation (pd) of dm and cp increased with inclusion of faveira pods, with 75.97 and 95.21%, respectively, for the level of 24%. There was increased potentially degradable fraction (bp) of ndf by 7.07% with inclusion of 24% faveira pods, as well as a reduced colonization time (lag) from 3.81 to 3.44 hours. The addition of up to 24% faveira pods to elephant grass silages improves rumen microbial degradation, and it is indicated this level of addition to obtain better quality silage.

“…The potential degradability (A) increased with the application of the levels of urea, this is explained by the reduction in the fiber content of straw, ammonia can act as alkali and act on ester bonds and thus it will act on the of the fibers and disruption of hydrogen bonds, consequently there will be a greater microbial degradation of particles (PIRES et al, 2010). Another point that can be highlighted is the increase in the nitrogen content in the material, once there is greater amount of non-protein nitrogen, which ensures the proper functioning of the ruminal microbiota and greater degradation of the fiber (LAZZARINI et al, 2009;GARCEZ et al, 2014). Considering that the largest amount of non-protein nitrogen provides a greater amount of nitrogen to ruminal bacteria (PEREIRA et al, 2010).…”

SUMMARY This study aimed to evaluate the chemical composition and in situ degradation dry matter of maize straw ammoniated with urea. This was a completely randomized design with five levels of ammoniation (0; 2; 4; 6 and 8% dry matter), with five repetitions. There was effect (P<0.05) of the ammoniation process on the retention of nitrogen in maize straw. For each 1% utilization of urea, we observed a reduction of 1.57% nitrogen retention. The dry matter content was not influenced (P>0.05) by the ammoniation; straw presented a mean value of 75%. In turn, the crude protein content increased (P<0.05) with ammoniation, increasing from 2.74% in the straw without treatment to 10 and 11% with the levels of 6 and 8% urea, respectively. For each 1% urea used, we found a reduction (P<0.05) of 0.65% in the neutral detergent fiber content of maize straw. The acid detergent fiber presented effect (P<0.05) in response to ammoniation. The technique provided a reduction of 0.69% acid detergent fiber for each 1% urea used. For dry matter degradation, we observed an increase in the soluble fraction up to the level of 6% urea. The ammoniation process favored the increase in the dry matter degradation rate of maize straw. It is recommended to conduct the ammoniation process in maize straw with 6% urea.
