Con el propósito de establecer si raciones preparadas en la finca podría sustituir a una ración comercial, se hizo un experimento con 32 cerditos de tres semanas de edad durante 35 días y fueron distribuidos en 16 lotes, quedando cuatro repeticiones para cada tratamientos. Los cerdos que mejor respondieron fueron los alimentados con la ración comercial, dando una ganancia de peso promedio por cerdo de 10.3 kilogramos, mientras que los cerdos alimentados con la ración "A" dieron 3.7 kgs., los alimentados con la ración "B" 9.0 kgs y el testigo 6.2 kilogramos. La eficiencia de conversión de los cerdos alimentados con la ración comercial fue mejor que las raciones preparadas en la finca, siendo la primera de 3.1, la ración "A" de 4.3 y la ración "B" de 3.7. El análisis estadístico demostró que había diferencias altamente significativas entre los tratamientos, siendo el mejor el tratamiento "C" o ración comercial.

El objetivo del presente trabajo fue evaluar la inclusión de harina de hoja de Marango (Moringa oleifera) en dietas para pollos de engorde y su efecto sobre el comportamiento productivo (Consumo, Ganancia media Diaria (GMD) , peso final (PF), Peso de la canal (PC), Rendimiento de la canal (RC), Conversión alimenticia (CA) ) así como su efecto sobre el tracto gastrointestinal (TGI) y calidad de la canal (CC) . Se utilizaron 210 aves de la línea Cobb 500 con peso promedio 30.09 g (0.5) . Se utilizó un diseño completamente al azar (DCA), distribuido en tres tratamientos con siete repeticiones. Los tratamientos fueron: T1:concentrado comercial, T2: concentrado con 5% de harina de hoja de Marango (Moringa oleifera ) y T3: concentrado con 10% de harina de hoja de Marango ( Moringa olei fera ). Los datos fueron analizados por PROC ANDEVA con el paquete estadístico SAS® Ver. 9.1 , las comparaciones de medias por la prueba de Tu key . No se encontraron diferencias (p>0.05) para consumo , GMD, PF, PC, y RC. Existieron diferencias (p <0.05) para CA T1 ( 1.6 ) supero a T3 ( 1.79 ) pero fue similar a T2 ( 1. 64 ) . La morfometría del TGI no se vio afectada en términos generales por los tratamientos en estudio. La CC no mostro diferencias entre los tratamientos, con una mejor aceptación de las canales provenien te de las aves alimentadas con harina de hoja de Marango (T2 y T3). La valoración financiera determino que el T2 es una alternativa viable para sustituir dietas basadas en alimentos comerciales, al generar mayores utilidades sin que esto afecte el peso final de las aves.

本文描述圆柱凸出物干扰区热流率的实验结果。实验中发现:上游中心线上最大传热率不发生在圆柱根部,而是位于离根部0. 1至0. 15倍圆柱直径处。对于垂直柱,当M=9,最大热流率为无柱平板当地值的46倍;而M=6. 6时为31倍。 圆柱倾斜对于干扰影响区域及最大传热率均有重大影响,尤以高马赫数时为最显著。当后掠30°时,最大热流率降为1/6。前倾使干扰影响区及最大热流率均增加。

We monitored litterfall biomass at six different sites of melaleuca (Melaleuca quinquenervia (Cav.) S.T. Blake) forested wetlands in South Florida from July 1997 to June 1999. Annual litterfall of melaleuca varied between sites from 6.5 to 9.9 t dry wt ha(-1) yr(1) over the two-year period. Litterfall was significantly higher (p < 0.0001) in scasonally flooded habitats (9.3 t ha(-1) yr(1)) than in non-flooded (7.5 t ha(-1) yr(1)) and permanently flooded habitats (8.0 t ha(-1) yr(1)). Leaf fall was the major component forming 70% of the total litter, woody material 16%, and reproductive material 11%. Phenology of flowering and leaf flush was investigated by examination of the timing and duration of the fall of different plant parts in the litter traps, coupled with monthly field observations during the two-year study. In both years, flowering began in October and November, with peak flowers production around December, and was essentially completed by February and March. New shoot growth began in mid winter after peak flowering, and extended into the spring. Very little new growth was observed in melaleuca forests during the summer months, from May to August, in South Florida. In contrast, the fall of leaves and small wood was recorded in every month of the year, but generally increased during the dry season with higher levels observed from February to April. Also, no seasonality was recorded in the fall of seed capsules, which apparently resulted from the continual self-thinning of small branches and twigs inside the forest stand. In planning management for perennial weeds, it is important to determine the period during its annual growth cycle when the plant is most susceptible to control measures. These phenological data suggest that the appropriate time for melaleuca control in South Florida might be during late winter and early spring, when the plant is most active.
