“…Triticale Yield and Estimated TMR Cost. In this study, triticale harvested at the boot stage yielded 5.7 t of DM/ha, which is more than twice the yield reported in Central Wisconsin by Coblentz et al (2018) when harvested at the same stage of maturity, but 58% lower than triticale harvested at dough stage in the semi-arid regions of Mexico (Reta et al, 2017). Future research in these regions should determine whether harvesting at an early stage of maturity may stimulate regrowth sufficiently for a second cut and thus enhance the overall nutrient yield compared with a single harvest at the dough stage of maturity.…”

“…In Mexico, triticale (× Triticosecale L.) is typically grown in the fall-winter season as a forage source for dry cows and heifers. Depending on stage of maturity at harvest, triticale can yield from 9.9 to 14.5 t of DM/ ha and contain from 11.0 to 15% CP and from 44.5 to 55.5% NDF (DM basis; Reta et al, 2017). These yields and composition are in contrast to those reported for temperate regions of the world.…”

In the semi-arid highlands of central Mexico, triticale (× Triticosecale L.) is emerging as an alternative, less water-demanding forage crop than alfalfa for dairy cattle. Studies reported here were aimed at evaluating triticale hay (TH) relative to alfalfa hay (AH) for lactating cow performance, apparent digestibility, N partition, and ruminal degradation kinetics of dry matter (DM), crude protein (CP), and neutral detergent fiber (NDF). Study 1 was conducted on a privately owned farm. Four barns were used to conduct 4 replicated 3 × 3 Latin squares (1 barn = 1 square), where each barn included 3 pens (experimental units) receiving 1 of 3 dietary treatments. Each pen had 62 Holstein dairy cows. All diets included a forage-to-concentrate ratio of 42:58 (DM basis), which is typical for intensive dairy farms of the region. Dietary treatments were formulated to replace AH with TH on a CP basis, and included (DM basis) 15.1% AH and 0% TH, 9.0% AH and 7.4% TH, and 0% AH and 16.4% TH. Diets were iso-energetic (1.64 Mcal of net energy for lactation/kg of DM) and iso-nitrogenous (17.9% CP). Pen-level DM intake and milk production were from all cows in the pen, but pen-level milk composition, apparent digestibility, and N partitioning were from 8 cows (observational units) randomly selected in each pen. Orthogonal contrasts were used to determine linear and quadratic effects of increasing TH from 0 to 7.4, and 16.4% of dietary DM. Although DM intake was not affected, there was a tendency for CP intake to decline linearly and for NDF intake to increased linearly as TH replaced AH in the diet. Milk production declined linearly by 0.077 kg/d for each additional percentage unit of TH in the diet, which amounted to a 3.5% decline when TH replaced AH entirely. However, no effect was observed on energycorrected milk production because of a compensatory linear effect of increasing milk fat concentration with the incorporation of TH in the diet. Total-tract NDF digestibility tended to increase linearly by 18.5%, but no differences were detected for urinary urea-N excretion and for N utilization estimated as milk N/(fecal N + urinary N + milk N). Study 2 was an in situ trial conducted to determine the degradation kinetics of AH and TH used in study 1. In spite of differences in degradation kinetics parameters for DM, CP, and NDF, only NDF effective ruminal degradation tended to be greater for TH than AH. Replacing AH with TH at the level typically found in intensive dairy farms of the semi-arid regions of Mexico had minimal effects on milk production and N utilization.

“…En México el cártamo es cultivado principalmente para la producción de aceite comestible y en los últimos años se han llevado a cabo experimentos para evaluar su uso como forraje ya sea ensilado o en fresco para ganado bovino y caprino (Landau et al, 2004;Reta et al, 2017). La producción de esta especie se concentra en el norte del país dentro de los estados de: Sonora, Baja California y Tamaulipas, con una superficie de 15 000, 2 600 y 1 910 ha sembradas.…”

El cártamo Carthamus tinctorius L. es un cultivo que ha sido adoptado por un gran número de productores, particularmente en el Noroeste del país, debido a su gran adaptabilidad y a su poco requerimiento hídrico, a causa de las grandes demandas que presenta la industria de oleaginosas en el país. Desde la década de los 70’s se ha trabajado para generar materiales que sean altamente productivos, con buen porcentaje y calidad de aceite y con características de resistencia a las principales enfermedades presentes en la región (falsa cenicilla y roya de la hoja). Por esto el objetivo de este trabajo fue evaluar el comportamiento de las líneas elite de cártamo generadas por el programa de mejoramiento genético en la región (23 oleicas y 1 linoleica). Dichas líneas se establecieron durante los ciclos 2017-2018 y 2018-2019. Se evaluó su comportamiento agronómico bajo las condiciones presentes del Valle del Yaqui. Se encontraron líneas del tipo oleico que superaron a los testigos Ciano ol y Chey ol, variedades que se siembran ampliamente en la región. Además, se encontró que la línea del tipo linoleico presentó mejores características agronómicas, producción y contenido de aceite que el testigo RC-1002 lo cual lleva a concluir que dentro de las líneas evaluadas hay materiales potenciales para ser liberados como variedad.
