“…Grasses of the genus Cynodon, such as Coastcross-1, have been widely used in tropical and subtropical regions to feed ruminants and horses, both as pasture form and as conserved forage, especially hay (Branco et al, 2012). Due to their response to fertilization, these grasses are usually grown using high amounts of chemical fertilizers, especially nitrogen fertilizers (Corrêa et al, 2007).…”

ABSTRACT. The high cost of nitrogen fertilizers increases the expenses in pasture-based animal production. The inoculation with plant growth-promoting bacteria is an alternative to reduce the costs. This study evaluated the forage yield of Coastcross-1 pastures inoculated with Azospirillum brasilense, fertilized with different levels of nitrogen and subjected to cuts. The experiment was a factorial randomized block design with three replications. The factors were the inoculation (without inoculation, inoculated only at planting and reinoculated in the second year), levels of nitrogen (0, 100 and 200 kg ha -1 year -1 N) and seasons (spring, summer, fall and winter) when cuts were made. Forage yield, forage accumulation rate, botanical and structural pasture composition were evaluated. Forage yield without nitrogen fertilizer in pastures was in the first year 9.1, 11.7 and 11.7 t ha -1 DM, and in the second year 8.6, 11.2 and 11.5 t ha -1 DM, for the factor inoculation, respectively. The forage yield rises with inoculation at pasture planting, without nitrogen fertilization. Reinoculation is not necessary.

“…So far, no single methods has been accepted as being reliably accurate for predicting the rumen CP degradation. In recent years, the CNCPS as an alternative for estimation of degradable protein has become widely accepted in the studies [12][13][14] , because CNCPS can be applied at the farm level and CP fractions could be measured easily in most feed analyses laboratories [15] . Morever, some researchers stated that in situ rumen degradability may be reliably and accurately predicted from CNCPS parameters [1,16,17] .…”

The objective of this experiment was to estimate in situ effective crude protein degradability (EPD) with Cornell Net Carbohydrate and Protein System (CNCPS) parameters [crude protein fractions (A, B 1 , B 2 , B 3 and C) and degradable protein intake value (DIP) values] of six energyrich feedstuffs. Four cereals: maize, wheat, barley, rye and two wheat middling (WM-1 and WM-2) were tested. The in situ effective protein degradability (EPD) was calculated using the nylon bag method where the test feedstuffs incubated in the rumen of three Tahirova wethers. The EPD's were estimated as EPD2, EPD5 and EPD8 assuming rumen outflow rates of 0.02, 0.05 and 0.08 h -1 . The crude protein fractions i.e. A=NPN, B 1 =fast, B 2 =intermediate, B 3 =slow and C=not fermented and unavailable to the animal were calculated using the soluble protein (SolP), the non-protein nitrogen (NPN, % of SolP), the neutral detergent insoluble protein (NDIP) and the acid detergent insoluble protein (ADIP=C) values of feedstuffs based on CNCPS. Then, DIP was calculated by using CNCPS crude protein fractions, degradation rate of B fractions (Kd) and coefficients of outflow rate on the different levels of dry matter intake (Kp): (DIP 1X =at 1x maintenance level of intake, DIP 2x =at 2x maintenance level of intake, and DIP 3x =at 3x maintenance level of intake). It was found that there was a significant multiple regression relation between the EPD8 (g/kg DM) and crude protein fractions (g/kg DM) (R 2 =0.96, n=18, P<0.001), and simple regression relation between the EPD8 (g/kg DM) and DIP 3X (g/kg DM) (R 2 =0.98, n=18, P<0.001). These regression relations did not improve when the different rumen outflow rates were used to estimate EPD. In conclusion, we claimed that in situ effective protein degradation (EPD) can be reliably and accurately predicted from CP fractions and DIP values in cereals and wheat middling.

Forage mass, botanical composition and stocking density of bermudagrass overseeded with forage legumes 1 Pastures of the genus Cynodon are being cultivated alone in conventional production with high rates of nitrogen fertilizer. Information and research about its use on mixed-pasture system is scarce. The objective of this study was to evaluate three grazing systems with coastcross-1 (CC) + 100 kg N ha . The experiment was carried out from May 2013 to April 2014. The sward height, forage mass, botanical composition, leaf:stem ratio, and animal stocking density were evaluated. Experimental design was completely randomized with three treatments (grazing systems) and three replicates (paddocks) in completely split-plot time (grazing cycles). The average stocking rate was 7.0, 6.8, 6.8 cows ha -1 day -1 for the respective forage systems. Better results were found with coastcross-1 mixed with common vetch + 100 kg N ha -1 year -1 in winter and spring and coastcross-1 alone + 200 kg N ha -1 year -1 in autumn.
