Abstract
Esta investigación se realizó en los meses de octubre a diciembre del 2012 y enero a febrero del 2013, en diez establos de las ciudades de Chiclayo, Lambayeque y Tumán de la región Lambayeque, con el objetivo de evaluar tres sistemas de alimentación de vacas de la raza Holstein - friesian sobre la calidad de sólidos totales de la leche. En sólidos grasos, Octubre y Febrero tuvieron 3,38; Noviembre: 3,37; Diciembre y Enero: 3,35. No se calcularon diferencias estadísticas significativas (p=0,05). El sistema de Chiclayo tuvo 3,40; Lambayeque: 3,36 y Tumán: 3,35. Se calcularon diferencias altamente significativas (p<0,01). En sólidos no grasos, Diciembre y Enero tuvieron 8,40; Noviembre: 8,38; Febrero: 8,36 y Octubre: 8,34. Se determinaron diferencias estadísticas altamente significativas (p<0,01). El sistema de Chiclayo tuvo 8,45; Lambayeque: 8,35 y Tumán: 8,32. Se calcularon diferencias estadísticas altamente significativas (p<0,01). En sólidos totales, Diciembre, Enero y Febrero tuvieron 11,75; Noviembre: 11,74 y Octubre: 11,72. No hubo diferencias estadísticas significativas (p>0,05). El sistema de Chiclayo tuvo 11,86; Lambayeque: 11,71 y Tumán: 11,66. Se encontraron diferencias altamente significativas (p<0,01). En proteína, Diciembre y Febrero tuvieron 2,76; Octubre, Noviembre y Enero: 2,75. No se determinaron diferencias significativas (p>0,05). El sistema de Chiclayo tuvo 2,90; Lambayeque: 2,71 y Tumán: 2,64. Se calcularon diferencias altamente significativas (p<0,01). En lactosa, Diciembre tuvo 4,53; Octubre, Noviembre, Enero y Febrero tuvieron 4,52. No se calcularon diferencias estadísticas significativas (p>0,05), El sistema de Chiclayo tuvo 4,60; Lambayeque: 4,52 y Tumán: 4,45. Se determinaron diferencias estadísticas altamente significativas (p<0,01). En ceniza, Octubre, Noviembre, Diciembre, Enero y Febrero tuvieron 0,66. No se determinaron diferencias estadísticas significativas. El sistema de Chiclayo y Lambayeque tuvieron 0,66; Tumán: 0,65. Se calcularon diferencias altamente significativas (p<0,01).
ABSTRACT This research was conducted in the months of October to December 2012 and January to February 2013, in ten stables in the cities of Chiclayo, Lambayeque and Tuman Lambayeque region in order to evaluate three feeding systems cows Holstein - friesian on the quality of total milk solids. In Fatty solids, October and February had 3,38; November: 3,37; December and January: 3,35. Statistically significant differences (p=0,05) were not calculated. Chiclayo system had 3,40; Lambayeque: 3,36 and Tuman: 3,35. Highly significant differences (p<0,01) were calculated. In non-fat solids, December and January had 8.40, November: 8,38; February: 8,36 and October: 8,34. Highly significant statistical difference (p<0,01) were determined. Chiclayo system had 8,45; Lambayeque: 8,35 and Tuman: 8,32. Highly significant statistical difference (p<0,01) were calculated. In total solids, December, January and February had 11,75; November: 11,74 and October: 11,72. There were no statistically significant differences (p>0,05). Chiclayo system had 11,86; Lambayeque: 11,71 and Tuman: 11,66. Highly significant differences (p<0,01) were calculated. In Protein, December and February had 2,76; October, November and January: 2,75. No significant differences (p>0,05) were determined. Chiclayo system had 2,90; Lambayeque: 2,71 and Tuman: 2,64. Highly significant differences (p<0,01) were calculated. In lactose, December had 4,53; October, November, January and February had 4,52. Statistically significant differences (p>0,05) were not calculated. Chiclayo system had 4,60; Lambayeque: 4,52 and Tuman: 4,45. Highly significant statistical difference (p<0,01) were determined. In ash, October, November, December, January and February had 0,66. Statistically significant differences were not determined. 4,52 system and Lambayeque had 0,66; Tuman: 0,65. Highly significant differences (p<0,01) were calculated.
