Bioeconomic Indicators of Ateleia cubensis (DC) Dietr for Production with Ruminants in Camaguey, Cuba.

Assessment of bioeconomic indicators of Ateleia cubensis (DC) Dietr. for production with ruminants was made, on ferromagnesium brown-red fersialitic soils of ultramafic savannahs in Camaguey, Cuba. The bioeconomic effect was simulated with a dual-purpose production system oriented to milk sales as the main product, on land covering 35 ha. The creation of a  protein bank is  recommended  in the area, using  A. cubensis  (DC) Dietr, on 15% of the total farm area. To simulate milk production response, feed balances were performed, all based on likely grass consumption and feeds used, according to their nutritional quality. The budget was portioned for analysis to determine  plant suitability for protein banks. Feasibility of the plant as a local source of protein for cattle was demonstrated through a bioeconomic perspectiv

Forage production and bromatological composition of Gliricidia sepium (Jacq) Kunth ex Walp

Forage production and bromatologic composition of Gliricidia sepium (Jacq) Kunth ex Walp were evaluated on cattle raising serpentine soils from the Livestock Center Noel Fernández in Camagüey, Cuba. Data were processed by the statistical package SPSS, and mean and standard deviation were determined. G. sepium foliage levels were significant (3,68 kg/a/cut for green matter and 1,33 kg/a/cut for dry matter) and raw protein levels were satisfactory (13,2 %)

Evaluation of dead leaf and soil creatures associated to Gliricidia sepium (Jacq) Kunth ex Walp, used as live fences in savannahs

The contribution of decayed dry leaves and edaphic fauna to soil by using Gliricidia sepium (Jacq) Kunth ex Walp as living fences on savannas  with a predominant  serpentine  stratum was determined  in Camagüey  municipality, Cuba. Results showed G. sepium beneficial environmental impact due to its high contribution of decayed dry leaves to soil, i.e., 332 kg/ha per month equivalent of 3,98 t/ha per year. Development of edaphic fauna earthworms and beetles mostly was enhanced, showing the benefits of this ecosystem environment, as well

sobre Fidel y el deporte

En la etapa pre-revolucionaria el deporte constituye un privilegio de las clases pudientes, el Estado no presta el interés necesario al fomento del deporte y la cultura física como formas para la satisfacción de las necesidades de la población pues no se considera un patrón para medir el nivel de desarrollo de la nación y menos un medio de poder político. En la mayoría de la población abundaron formas de recreación enajenantes, vicios como las peleas de gallo que lejos de ayudar al desarrollo espiritual o físico hacía a los hombres y mujeres esclavos de los sueños por obtener dinero

Native Pasture Quality in Cattle Raising Areas on Ultramafic Groundmass.

The quality of native pasture in cattle raising areas on ultramafic groundmass, in the municipality of Minas, Cama-güey, Cuba,  was assessed. The area studied has brown Fersialitic, ferromagnesial soil (Inceptisol-Cambisol). The climate is tropical humid. Dry matter, calcium, phosphorous and raw protein were estimated for compound samples of the predominant pastures, using an AOAC  methodology at the Provincial Soil Management, in Camagüey. De-scriptive statistics for the bromatological composition (mean and standard error) were determined, considering every species, season and group. Group comparison was made by the Kruskal-Wallis test. Legume quality in both seasons had protein levels above 7 % in all the cases; whereas graminaceae quality had values under that percent. In all the cases, the contents of P are insufficient to meet the minimum needs, and the protein and calcium values   are near the required limits for cattle

Edad y conducta sexual en Triatoma pallidipennis Stal (hemiptera reduviidae) en condiciones de laboratorio

La conducta sexual de varias especies de triatominos ha sido estudiada. Estos tienen una gran relevancia por los aportes potenciales que podrían brindar para el control de las poblaciones de estos vectores. Triatomapallidipennis es la especie más abundante en México y poco se conoce sobre el comportamiento sexual. Se utilizaron cinco grupos de ejemplares de T. pallidipennis, con tres repeticiones del experimento para cada grupo, en los que se evaluó la ocurrencia de cópula de 1 hembra y 3 machos ambos con distinta edad y estados nutricionales. Se observó lacópula de 10 hembras de un total de 15. Los machos viejos con ingesta de sangre o sin alimentar fueron los seleccionados por las hembras, lo cual demuestra que las hembras eligen sus parejas por la edad del macho. Seobservaron rechazos ante los intentos de cópula del macho en esta especie. Las hembras copularon una vez, aunque en pocos casos, finalizada esta con los machos viejos, la mantuvieron con un macho joven, no pudiéndose comprobar competencia espermática. Las hembra de T. pallidipennis aceptan a los machos más viejos para la cópula la cual ocurre de manera general una sola vez, no evidenciándo un sistema poliándrico en este estudio.Fil: Moralez Ortiz, Iris.

Grass Availability in Ultramafic Cattle Areas.

Availability of grass in ultramafic cattle areas in Camaguey, Cuba, was determined. The research comprised the 2004-2013 period  in the rainy and dry seasons.  The area has  Brown Fersialitic Ferromagnesial Soil (Inceptisol-Cambisol). Total and individual  species’ availabilities  were tested using the practical variant of the Haydock and Shaw visual method for production areas.  Sampling was made at the beginning of each rotation (five in the rainy season and three in the dry season) at a rate of 100 observations/ha.  Forage balance was determined for the rainy and dry seasons, and the botanical composition was assessed using the steps method, and dry matter yields were determined in situ.  SPSS 15.0.1 was used to make the statistical analysis. Descriptive statistical analysis for Mean and Standard deviation were determined  for availability of each species.  Grass availability in the ecosystems is 5.15 t MS/ha, distributed in 2.83 t MS/ha in the rainy season; and 2.31 t MS/ha in the dry season. The forage balance showed a deficiency in feedstuffs in the two seasons, affecting milk production and the reproduction indicators

Economic and Productive Characterization of Dairy Units Integrated to the Municipal Cattle Raising Program (PROGRAM) in the Province of Camagüey, Cuba.

The economic and productive behaviors  of dairy units were characterized between 2009 and 2013, integrated to the Municipal Cattle Raising Program (PROGRAM).Ten dairy farms were chosen in the study, grouped in four agricultural enterprises of Camagüey.  The main principle of the experiment was to achieve food self-sufficiency  in the farms. The study was divided into three stages: (I) characterization of limitations by a farm diagnostics; (II) proposal and incorporation of technologies; (III) follow up and evaluation of results. The analysis included economic and productive indicators suggested by the Ministry of Agriculture. Forage balances were made, and  a  pasture-forage arrangement was set up, according to the results provided by the REGPAST software. The methodology established by Toro (2011) was used for characterization  in  three stages:  variable reviewing  and selection,  Principal  Component Analysis, and Conglomerate Analysis. The results showed an increase of economic and productive indicators at the end of the stage, which helped determine system behavior. Moreover, all the indicators selected were included in some components, which explains the 89 % of total variability. Accordingly, three groups of dairy units were set up, corresponding with the development programs for each, with mean values of 1 553.0 kg per hectare for  the first group; 874.25 kg, for the second; and 1 361.67 kg, in the third group

Evaluación de la presencia de leguminosas sobre suelos Fersialítcos Pardo Rojizos en áreas de pastoreo del Municipio Minas. Camagüey. I. Prospección

The gradual decrease in number and diversity of vegetable species (arboreal, shrubby and herbaceous) has converted to vulnerable to an increasing area in tropical regions where cattle raising is developed, causing serious problems of deterioration of soils and deep decreasing in yields. The lack of knowledge on the leguminous species existing in shepherding ecosystems on Reddish Brown Fersialitic soils, limit their sustainable use in association with gramineous. Because of this, the objective of our investigation was addressed to prospect the species of leguminous and gramineous existing in these ecosystems in order to evaluate in later works their productive and nutritional potential, with emphasis in the existent species of leguminous. The experience lasted 6 months, three of them corresponding to the dry season and three to the rainy one, from February to July 2006. The evaluations were carried out in an area located at 21º28'50" - 21º29' 15" of northern latitude and 77º39'50" - 77º40'20" of western longitude , in an area of 26,24 ha and an altitude of 85 mosl .La gradual disminución del número y diversidad de especies vegetales (arbóreas, arbustivas y herbáceas) ha convertido en vulnerable a una creciente área donde se desarrolla la ganadería en las regiones tropicales, provocando serios problemas de deterioro de los suelos y disminución creciente de los rendimientos. El desconocimiento de las especies de leguminosas existentes en los ecosistemas de pastoreo sobre suelos Fersialíticos Pardo Rojizos, limitan su uso sostenible en asociación con gramíneas. Por ello el objetivo de nuestra investigación estuvo encaminado a prospectar las especies de leguminosas y gramíneas existentes en estos ecosistemas con vistas a evaluar en trabajos posteriores su potencial productivo y nutricional, con énfasis en las especies de leguminosas existentes. La experiencia tuvo una duración de 6 meses, tres de ellos correspondientes al periodo seco y tres al lluvioso, iniciándose en febrero del 2006 hasta Julio del mismo año. Las evaluaciones se realizaron en aéreas situadas a los 21º28’50” - 21º29’ 15” de latitud norte y los 77º39’50” - 77º40’20” de longitud Oeste, en un zona de 26,24 ha y una altitud de 85 msnm

Indicadores bioeconómicos del uso de Ateleia cubensis (DC) Dietr. para la producción con rumiantes en Camagüey, Cuba.

Se evaluaron los indicadores bioeconómicos de Ateleia cubensis (DC) Dietr. para la producción con rumiantes en suelo fersialítico rojo pardusco ferromagnesial, de las sabanas ultramáficas de Camagüey, Cuba. Se simuló el efecto bioeconómico en un escenario con un sistema de producción de doble propósito orientado a la venta de leche como producto principal, con 35 ha de superficie, donde se propone el fomento de un banco de proteínas con A. cubensis (DC) Dietr. en el 15 % del área de la finca. Para simular la respuesta en términos de producción de leche, se realizaron balances alimentarios, basados en el consumo probable de los pastos y alimentos utilizados, según su calidad nutritiva. Se analizaron los presupuestos parciales para determinar la factibilidad del uso de esta planta en bancos de proteínas. Desde el punto de vista bioeconómico se demostró su factibilidad como banco de proteína, para la ganadería vacuna en la zona.Bioeconomic Indicators of Ateleia cubensis (DC) Dietr for Production with Ruminants in CamagüeyABSTRACTAssessment of bioeconomic indicators of Ateleia cubensis (DC) Dietr for production with ruminants was made on ferromagnesium red-brown fersiallitic soils of ultramafic savannah in Camagüey, Cuba.
