“…PG1 and PH elephant grass become widely grown in southern subtropical China due to their very high DM and protein content. Although the growing season is shorter than that in Thailand, DM of M II, PU, and SU were much higher than those reported at northeast Thailand [13] [15] [22]. The reason may be that sufficient heat, water and radiation at our subtropical site facilitate these plant to photosynthesize and produce biomass; Comparatively, at northeast Thailand, the long dry season from winter to early summer, and following long rainy and dully summer days which result in periodic water and radiation deficiency leading to photosynthesis and biomass reduction [15] [22].…”

Forage production and quality of five tropical grass accessions (Guimu-1 hybrid elephant grass (PG1), Mulato II (M II), Ubon paspalum (PU), hybrid elephant grass (PH) and Reyan 11 paspalum (PR11)) and two tropical legume accessions (Reyan 5 stylo (SR5) and Ubon stylo (SU)) were evaluated in a field experiment in a subtropical area with hot summers and cold winters in Guangxi, China. Three forage stubble cover managements: no cover (CK), dry mass cover (MC) and plastic cover (PC) were applied at the end of the summer period to evaluate cold tolerance and accession survival over the winter. Photosynthesis measurements were taken from the forages in mid-summer. The results showed that PG1 accession produced significantly higher dry matter yields (67.0 t·ha −1 ) than the other grass and legume accessions. Legume accessions SU and SR5 produced much less dry matter (6.4 -7.2 t·ha −1 ) compared to the grasses. M II, PU and PR11 contained the largest proportion of leaf. PG1 and PH showed good cold tolerance (survival rate >85%) under −1˚C conditions without any cover management. PR11 had better cold tolerance than PU. M II exhibited very poor winter survival under no cover and with massive cover, and only survived well under plastic cover. The two stylo accessions died completely under all winter cover management treatments. In the growing season, under a given photosynthesis photon flux density (PPFD) = 1500 μmol m . Though these 7 tropical accessions yielded high production in the grow season, stylo and M II are sensitive to cold in subtropical region of Guangxi. The result suggests that PG1 and PU are good accessions and can be used as productive perennial pasture, while stylo and M II are How to cite this paper:

“…Hare et al (31,32) , informaron que el FDN de pastos del género Brachiaria (cultivares Mulato II, Cayman y la linea BRO2/ 1794), y de Panicum (Mombasa y Tanzania), fertilizados con NPK, evaluados a 4, 6, 9 y 12 semanas variaron entre 51.9 a 63.3 y 62.3 a yearly average of 13.7 ± 12.8 kg (27) . It is considered that growth differences between plants in small plots and grasslands are due to microenvironments originated by the different managements that are applied to the plants as a consequence of the grazing activity of the animals.…”

RESUMENEl presente trabajo se realizó con el objetivo de determinar el rendimiento de materia seca (RMS), y la degradabilidad ruminal de la materia seca (MS) y la energía, de diez pastos de los géneros Brachiaria: B. brizantha (Insurgente), B. decumbens (Señal), B. humidicola (Chetumal), B. brizantha x B. ruzieziensis (Mulato I); Panicum: P. maximum cv. Mombasa, P. maximum cv. Guinea, P. maximum cv. Tanzania; y Pennisetum: P. purpureum cv. Taiwan, P. purpureum cv. Cuban king grass, P. purpureum cv. Purple king grass, a 3, 6, 9 y 12 semanas de rebrote, en tres ciclos de crecimiento. La degradabilidad ruminal de MS y energía se determinó a 48 h de incubación in situ. El RMS fue 3,037, 1,689 y 1,872 kg ha -1 , para Pennisetum, Brachiaria y Panicum (P<0.05). La PC disminuyó de 11.6 a 6.9 % (3 a 12 semanas), sin diferencias entre géneros. ABSTRACTThe objective of the study was to determine dry mater yield (DMY), and in situ ruminal degradable dry matter and energy of ten grasses of the genera Brachiaria: B. brizantha (Insurgente), B. decumbens (Señal), B. humidicola (Chetumal), B. brizantha x B. ruzieziensis (Mulato I); Panicum: P. maximum cv. Mombasa, P. maximum cv. Guinea, P. maximum cv. Tanzania; and, Pennisetum: P. purpureum cv. Taiwan, P. purpureum cv. Cuban king grass, P. purpureum cv. Purple king grass, at 3, 6, 9 and 12 wk of regrowth, in three evaluation cycles. DMY for Pennisetum, Brachiaria and Panicum was: 3,037, 1,689 and 1,872 kg ha -1 (P<0.05). CP concentration decreased from 11.6 to 6.9 % (3 to 12 wk), without differences among genera. Concentration (%) of NDF, ADF and LIG were: 72.1, 43.5 and 8.1 (Brachiaria); 73.0, 45.8 and 9.0 (Panicum); and 68.8, 44.4 and 9.1 % (Pennisetum), values were 68.1, 40.1 and 8.2 (at 3 wk); and 76.2, 49.7 and 9.5 (at 12 wk). The in situ DM degradability was: 70.0 % (Brachiaria), 65.8 % (Panicum) and 72.9 % (Pennisetum) and decreased from 71.7 to 62.9 % (from 3 to 12 wk). Gross energy (GE) preincubation, was 3,802, 3,756, and 3,608 kcal kg -1 DM, for Brachiaria, Panicum, and Pennisetum, with no changes due to age of regrowth. In situ ruminal energy degradability (as % of incubated GE) was: 55.6, 51.4, and 57.9 % for Brachiaria, Panicum; and Pennisetum. In conclusion, age of regrowth and genus affected the nutritive value of the evaluated grasses. INTRODUCCIONEn las regiones tropicales, los sistemas de producción bovina están basados en el pastoreo de gramas nativas (1) , cuya productividad varía en cantidad y calidad (2) , por lo que es importante la selección efectiva e introducción de pastos de alta calidad nutricional, y alta producción forrajera, adaptados a las condiciones locales de clima, suelo y manejo (3) .La edad del pasto al corte o pastoreo afecta la calidad y digestibilidad de las pasturas (4,5) , debido a un incremento en la proporción de pared celular respecto al contenido celular, así como en mayor cantidad de tallos y material muerto en la planta conforme ésta madura. Los pastos con baja digestibilidad retardan el paso del alimento a través del tracto di...

The sustainability of the livestock sector in sub-Saharan Africa is negatively affected by limited access to highquality fodder in adequate quantities. The effects of climate change further exacerbate feed availability. Therefore, there is a need to develop feasible cost-effective strategies for improving the year-round feed supply. Improved planted forages such as Brachiaria grass have been recommended as one of the strategies of alleviating feed scarcity, especially in drier agro-ecological zones. This study analyses the socio-economic determinants of adoption and the impact of adopting Brachiaria grass for feed sufficiency and increased milk production. Propensity Score Matching (PSM) method was used to assess the determinants and impact of the adoption of Brachiaria grass. Empirical results indicate that the adoption of Brachiaria grass led to a significant increase in milk production by 27.6% and feed sufficiency by 31.6%. The positive impact of Brachiaria grass is consistent with the role of agricultural technologies in improving the productivity, income, and welfare of smallholder farmers. The adoption of Brachiaria grass is influenced by age of farmer, tropical livestock unit (TLU), type of animal breed, perceived benefits of the technology, access to extension, and farmer group membership. The study recommends holistic policy approaches that promote the widespread adoption of Brachiaria grass. There is also a need for an effective information dissemination pathway for Brachiaria grass.
