Forage yield of cutting grass and effect on compositional quality and yield of milk in a dry Caribbean

Seasonal climates affect the supply of nutrients in livestock systems. In search of different strategies for feeding livestock, we evaluated the effect of nitrogen fertilization of four cut grasses on yield and feed quality in dual purpose cows in Valle del Cesar. Two phases were developed, the firs...

description Seasonal climates affect the supply of nutrients in livestock systems. In search of different strategies for feeding livestock, we evaluated the effect of nitrogen fertilization of four cut grasses on yield and feed quality in dual purpose cows in Valle del Cesar. Two phases were developed, the first was the assessment of the performance and quality of feed, where the data were analyzed by a randomized block design with a factorial arrangement of four grasses and five nitrogen sources, the second phase evaluated the animal response, supplying feed based on results in the first phase, using a change-over experimental design. Eight dual purpose cows in the second third of lactation with a weight (W) of 395 kg about were used. The study was conducted at the Motilonia Experimental Station. The type of pasture significantly affected the value for dry matter, being highest in Elefante grass (17.9%) and lowest in morado King-grass (13.3%); feed yield was affected by both fertilization and pasture, being highest in the application of urea and in partnership with Leucaena sp. (12.9 and 12.7 t ha-1, respectively). Fertilization had no effect on the chemical composition of the grasses. We obtained a higher milk production when silage of Elefante grass + Leucaena sp. and Elefante alone (3.98 ± 0.18 and 3.81 ± 0.18 L/cow/day) were supplied, compared to feed without silage. The compositional quality of the milk was positively affected by the silage.

En la búsqueda de diferentes estrategias para la alimentación del ganado, se evaluó el efecto de la fertilización nitrogenada de cuatro gramíneas de corte sobre el rendimiento, la calidad del forraje en vacas doble propósito en el Valle del Cesar. Se desarrollaron dos fases, la primera, consistió en la evaluación del rendimiento y calidad del forraje, dónde los datos se analizaron por un diseño en bloques al azar, con un arreglo factorial de cuatro forrajes y cinco fuentes nitrogenadas; la segunda fase consistió en la evaluación de la respuesta animal; se suministró forraje conservado basados en los resultados de la primera fase; se aplicó un diseño experimental de sobrecambio. Se utilizaron 8 vacas doble propósito en el segundo tercio de lactancia con un peso (PV) de 395 kg aproximadamente. El estudio se realizó en la Estación Experimental Motilonia, Corpoica. El tipo de pastura afecto significativamente el valor de la materia seca, siendo mayor en el pasto Elefante (17,9%) y menor en el King-grass morado (13,3%); el rendimiento de forraje fue afectado tanto por la fertilización, como por la pastura, siendo mayor en la aplicación de urea y en asociación con Leucaena sp. (12,9 y 12,7 t ha-1, respectivamente). La fertilización no tuvo efecto sobre la composición química de las gramíneas. Se obtuvo una mayor producción de leche, cuando se suministró ensilaje de pasto Elefante + Leucaena sp. y de Elefante solo (3,98 ± 0,18 y 3,81 ± 0,18 L/vaca/día), en comparación con la alimentación sin suministro de ensilaje. La calidad composicional de la leche se vio afectada positivamente por el suministro de ensilaje.   Ganado de leche-Ganadería lecheapplication/pdfspa‎‎Corporación colombiana de investigación agropecuaria - AGROSAVIABogotá (Colombia)http://revistacta.agrosavia.co/index.php/revista/article/view/242/246Attribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/http://purl.org/coar/access_right/c_abf2Revista Ciencia y Tecnología Agropecuaria; Vol 13 No 1 (2012); 71-78Forage yield of cutting grass and effect on compositional quality and yield of milk in a dry CaribbeanRendimiento de forraje de gramíneas de corte y efecto sobre calidad composicional y producción de leche en el Caribe secoGanadería y especies menoresarticleArtículo científicohttp://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/resource_type/c_6501info:eu-repo/semantics/articlehttps://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85THUMBNAILVer_Documento_35125.pdf.jpgVer_Documento_35125.pdf.jpgIM Thumbnailimage/jpeg9591https://repository.agrosavia.co/bitstream/20.500.12324/35125/2/Ver_Documento_35125.pdf.jpgf940b28ff91cfe0e30eb7990f5b99002MD52open accessORIGINALVer_Documento_35125.pdfVer_Documento_35125.pdfapplication/pdf453563https://repository.agrosavia.co/bitstream/20.500.12324/35125/1/Ver_Documento_35125.pdf6e03eb1a508d0a16cac314348ab150ecMD51open access20.500.12324/35125oai:repository.agrosavia.co:20.500.12324/351252024-09-17 11:54:26.893open accessAgrosavia - Corporación colombiana de investigación agropecuariabac@agrosavia.co
