Contenido : |
La inseminación artificial (IA) en los rodeos de cría a nivel mundial, regional y local fue muy poco usada, por lo menos hasta fin del siglo pasado. La presente publicación comienza con tres capítulos para ubicar la inseminación artificial en el contexto de las técnicas reproductivas a nivel regional y mundial (Capítulo I), comprender los objetivos de sincronización e inducción de ovulaciones (Capítulo I y II) y entender la tecnología reproductiva de IATF (Capítulo III) que no solamente sirve para la
introducción de material genético sino como una herramienta de manejo del rodeo de cría tal como lo muestran los resultados del presente Proyecto (Capítulo IV). Este último capítulo, base de esta publicación, presenta los resultados de cuatro experimentos correspondientes a las categorías que componen un rodeo de cría, que fue financiado por INIA (Proyecto 302). |

In the symbiotic relationship between tall fescue (Festuca arundinacea SHREB.) and the endophytic fungus Epichloë coenophialum, the compounds produced by the later offers survival benefits to the infected grass. Novel endophyte strains offer such advantages, with no toxicity associated to cattle. However, whether both the biotic and abiotic stress tolerance attributed to the endophyte infection result in an increase in dry matter productivity remains unclear. Thus, the objective of this study was to determine if tall fescues infected with the novel endophyte strain AR584 performed better than its endophyte-free counterpart in the temperate region of Uruguay. From 2010 to 2017 two cultivars, INIA Aurora and INIA Fortuna, with and without the AR584 endophyte (E+ and Nil respectively) were sowed in the tall fescue field trials of INIA?s breeding program. These cultivars along with other breeding lines were sowed in 6.25 m2 plots, with 4 reps in randomized complete block design, and were evaluated for 3 years periods. Both, seasonal and annual dry matter (DM) production of the swards were evaluated under cuts. Analysis of the data shows that Cultivar INIA Aurora E+ had higher annual DM yields than INIA Aurora Nil in swards of all 1st, 2nd and 3rd years, but differences were not significant (P>0.05). The seasonal DM yields were also higher in INIA Aurora E+ in all but one season, although the difference was significant only in spring of the 1st year (P<0.05). On the other hand, cultivar INIA Fortuna E+, had higher annual DM yields in swards of 1st and 2nd years and lower yield in 3rd year than INIA Fortuna Nil but differences were never significant (P>0.05). Except for the 3rd winter and spring, seasonal DM yields were higher for INIA Fortuna E+, but again the differences were not significant (P>0.05). For the total DM production over 3 years of evaluation, INIA Aurora E+ produced 4.9% and INIA Fortuna E+ produced 1.4% more than their respective Nil versions. Levels of infection measured by blotting test averaged 91±5.5 for INIA Aurora E+, 3±2.2 for INIA Aurora Nil, 93±3 in INIA Fortuna E+, and 25±7.9 in INIA Fortuna Nil. Although data can be further analyzed, these preliminary analysis suggests that the novel endophyte AR584 provides a small, but not significant advantage, in DM production to, infected tall fescue cultivars in mild environments.
