 en Use of deep litters for fattening pigs fed with sugar cane molasses
Cruz, Elizabeth; Almaguel, Ramiro Ernesto; Mederos, Carmen María & Ly, Julio

Abstract

In order to evaluate the deep bedding technology as alternative for fattening pigs in the rural sector, in Cuba. Two rearing cycles of 106 days with 108 animals each (castrated males and females), YL (Camborough) cross, of approximately 21,0 kg live weight and 75 days average age were used. The pigs were distributed into a random block design with three treatments for each cycle: T1, deep bedding based on gramineous hay; T2, deep bedding based on dried sugar cane bagasse (80%) and gramineous hay (20%) and T3, solid concrete floor, with four repetitions by treatments. The animal performance traits (up to approximately 100 kg live weight) were studied. A chemical and microbiological evaluation of the bedding material was made. There were significant differences for the consumption and the alimentary conversion (P <0,05) to the pigs housed in hay bed, bagasse and hay bed and solid concrete floor: 2,53; 2,50; 2,74; 3,42; 3,38 y 3,60 respectively. Significant differences were obtained (P <0,01) for the nitrogen and the phosphorous in the bedding material at the end of the experience: 1,43 and 1,85, respectively. There was not presence of Salmonella check for this species in other resources sp and helmints eggs. It was saved 360 m3 of water. It was conclude that the deep bedding technology is an alternative that satisfies the current demands of the rural pig producers in Cuba.

Keywords
deep bedding, helmints, performance traits, Salmonella.

 
 es Uso de camas profundas en los sistemas de engorde de cerdos en el sector campesino en Cuba
Cruz, Elizabeth; Almaguel, Ramiro Ernesto; Mederos, Carmen María & Ly, Julio

Resumen

Se evaluó la tecnología de cama profunda como alternativa para el engorde de cerdos en el sector campesino en Cuba. Realizándose 2 ciclos de crianza de 106 días con 108 animales cada uno (hembras y machos castrados), de la raza Yorkshire Landrace YL (Camborough), de aproximadamente 21,0 kg de peso vivo y 75 días de edad como promedio, distribuidos en un diseño de bloques al azar en 3 tratamientos en cada ciclo: T1, piso de tierra con cama de heno de gramíneas; T2, piso de tierra con cama de bagazo de caña seco (80%) y heno de gramíneas en la superficie (20%) y T3, piso de concreto sólido, con 4 repeticiones por tratamiento. Se midieron los rasgos de comportamiento animal hasta el peso de sacrificio (100 kg). Se realizó una evaluación química y microbiológica de los materiales usados como cama al inicio y final de la experiencia. Hubo diferencias significativas en el consumo y la conversión alimentaria (P <0,05), entre los cerdos alojados en cama de heno, cama de bagazo y heno, y piso de concreto: 2,53; 2,50; 2,74; 3,42; 3,38 y 3,60 respectivamente. Se observaron diferencias significativas (P<0,01), para el nitrógeno y fósforo en el material de las camas al final de la experiencia: 1,43 y 1,85, respectivamente. No hubo presencia de Salmonella check for this species in other resources sp. ni huevos de helmintos. Se ahorraron 360 m3 de agua. Se concluye, que la tecnología de cama profunda es una alternativa que satisface las demandas actuales de los productores porcinos provenientes del sector campesino en Cuba.

Palabras-clave
