Se utilizaron 22 cerdos machos y hembras en iguales proporciones de 17.5 kg de peso vivo promedio distribuídos de acuerdo a un diseño de clasificación simple en dos tratamientos y 11 réplicas. Los tratamientos experimentales consistieron en: I-Suministrarles a los cerdos agua de beber normal y II- Suministrarles agua tratada magnéticamente (T.M.A) a 2542 gauss y una velocidad de flujo de 1 m/s, para estudiar la influencia que ejerce el agua tratada magnéticamente sobre los principales rasgos de comportamiento de los cerdos en ceba alimentados con dietas basadas en miel B y harina de soya. No se encontraron diferencias significativas entre tratamientos para los pesos finales (kg), ganacias de peso (g/día), consumo MS (kg) y conversiones alimentarias (kg MS/kg aumento) siendo sus valores de 96.70 y 95.70; 727 y 719; 3.0 y 3.0; 4.15 y 4.14 respectivamente. No se observó efecto sobre el comportamiento animal al utilizar agua tratada magnéticamente a los niveles de inducción y flujo empleado en esta prueba. | Twenty two male and female pigs with 17,5 kg live weight as average were distributed according to a single classification in two treatments and 11 replications. The experimental treatments consist in: I- suppling normal drinking water to the pigs and IIMagnetical 2542 gauss treated water and a speed flow 1 m/s, in order to study the influence of magnetical treated water on the main trait performance of fattening pigs fed with diets based in type B molasses and soy bean meal. No significant differences were found betwen treatments for the final weight (kg), daily gains of weight (g/day), feed intake of DM (kg) and feeding conversions (kg DM/kg gains). The values were: 96,70 and 95,70; 727 and 719; 3,0 and 3,0; 4,15 and 4,14 respectively. No effect was encountered in the use of magnetical treated water under the parameter probed in this trial.

Se compararon dos sistemas de bebederos de agua (Tetinas y en Comedero) y dos niveles de proteína según los requerimientos del NRC (1988) (50 y 70 %) en 24 cerdos machos castrados y hembras (1:1) de la línea sintética cubana CC21 de 23 kg de peso vivo promedio alimentados principalmente con miel final de caña de azúcar y una mezcla de harina de maíz y soya. Para el análisis matemático se empleó el método de los mínimos cuadrados en un modelo factorial 2x2x2 que tuvo en cuenta los efectos del sistema de bebedero, la norma de alimentación y el sexo como causas de variación. El consumo de MS (kg/día), proteína (g/día), ganancia diaria (g), conversión alimentaria (kg MS/kg aumento) y proteica (kg PB/kg aumento), para la norma nutricional de la proteína según requerimientos establecidos hubo efecto significativo (P∠ 0,001) y fueron: 50 % (2,13; 154; 405; 5.30 y 0.382 respectivamente) y el 70 % (2,25; 222; 515; 4.38 y 0.431 respectivamente) salvo para la conversión proteica que presentó menor diferencias (P∠ 0.01) y el consumo de MS que no fueron diferentes entre tratamientos estudiados. Aunque no se encontraron diferencias entre los sistemas de ofrecimiento de agua y para el sexo, si se observó un efecto biológico favorable cuando se utilizaron las tetinas, donde se ahorran 0.2 unidades de conversión alimentaria y una mejora de 30 grs de ganancia diaria. De acuerdo con los resultados alcanzados es posible reducir los niveles de proteína hasta el 70 % sin que se afecten notablemente los rasgos de comportamiento y es recomendable que no se cambien los actuales sistemas de bebederos (Tetinas) por el ofrecimiento directo de agua a los comederos tanto del punto de vista de comportamiento como de salud de los animales | Two systems of drinking troughs of water were compared (Tetinas and in Trough) and two protein levels according to the requirements of the NRC (1988) (50 and 70%) in 24 castrated male pigs and females (1:1) of the Cuban synthetic line CC21 of 23 kg of weight average fed mainly with final honey of cane of sugar and a mixture of flour of corn and soya live. For the mathematical analysis the method of the square minim was used in a factorial model 2x2x2 that she/he kept in mind the effects of the drinking trough system, the feeding norm and the sex like variation causes. The consumption of MS (kg/día), protein (g/día), daily gain (g), alimentary conversion (kg MS/kg increase) and protein (kg PB/kg increase), for the nutritional norm of the protein according to established requirements had significant effect (P (0,001) and they were: 50% (2,13; 154; 405; 5.30 and 0.382 respectively) and 70% (2,25; 222; 515; 4.38 and 0.431 respectively) except for for the conversion protein that presented smaller differences (P (0.01) and the consumption of MS that you/they were not different among studied treatments. Although they were not differences among the systems of offer of water and for the sex, if a favorable biological effect was observed when the tetinas was used, where 0.2 units of alimentary conversion and an improvement of 30 grs of daily gain are saved. In accordance with the reached results is possible to reduce the protein levels until 70% without they are affected the behavior features notably and it is advisable that the current systems of drinking troughs are not changed (Tetinas) for the direct offer of water to the so much troughs of the behavior point of view like of health of the animals

The experiment consisted in evaluating the productive behavior of fattening chicken, fed with fish meal, with different levels of inclusion of fish solubles, obtained starting from stickwater which was stored in plant for different times. Five hundred and sixty, non-sexed, four days-old Hubbard broilers chicken, were used, distributed into seven treatments with four replications of twenty chicken each one. The experimental design was at random blocks, with a 2x3 factorial arrangement, in which the variables were: a) storage time of the stickwater (6 and 24 hours), and b) levels of inclusion of fish solubles in the fish meal (4.6, 9.3 and 14.0%), including a comparative basis which were suited to a standard or common fish meal, without incorporating fish solubles. The evaluations were live body weight variations, food consumption, alimentary conversion and chicken death rate. The increases on live weight of the chicken, for the total period, fluctuated between 1568 and 1698 g/chick; the food consumption varied from 4045 to 4437 g/chick; the alimentary conversion was from 2.46 to 2.79 kg/kg and the death rate reached a value of 2.14%. It was concluded that the use of fish solubles in chicken feeding did not alter their productive behavior. The results showed that it is feasible to retrieve the fish solubles, starting from stickwater stored in plant for up to 24 hours, with consequent environmental and economic profit for the industry.
