7 & 7 Synch and 7-day progesterone- based protocols for estrus synchronization prior fixedtime artificial insemination in multiparous beef sucked cows
(ICAR, 2022-06)Estrogen-based protocols combined with a progestinreleasing intravaginal device (P4RID) and prostaglandin (PG) synchronize follicle wave emergence prior to artificial insemination (AI) in Bos taurus, with pregnancies per ... -
Bases moleculares de la fertilidad de la espiga en trigo pan
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2018-03)El trigo pan es uno de los cultivos de granos más importantes del mundo. Uno de los principales objetivos del mejoramiento genético a nivel mundial es el aumento del rendimiento en grano. El rendimiento es un carácter ... -
Criterios de selección por fertilidad de la hembra en bovinos para carne
(Universidad Nacional de Mar del Plata , Facultad de Ciencias Agrarias, 2017-06)El objetivo de este estudio fue identificar criterios de selección para mejorar la aptitud reproductiva de la hembra bovina. Para ello se realizaron estudios de pubertad en vaquillonas, y productividad media anual en vacas. ... -
Effect of Protein Restriction During Mid-to Late Gestation of Beef Cows on Female Offspring Fertility, Lactation Performance and Calves Development
(E-Cronicon, 2019-12)Cow calf operation in Argentina are managed under extensive grazing condition and the quality of forages is often poor during second half of gestation. Protein restriction in bovine gestation affects production traits in ... -
Effects of photoperiod sensitivity genes Ppd‐B1 and Ppd‐D1 on spike fertility and related traits in bread wheat
(Wiley Online Library, 2018-04-27)Increasing grain yield is a key breeding goal in bread wheat. Several authors have suggested that a spike fertility index (SF), that is the quotient between grain number per unit spike (GNS) and spikechaff dry weight (SCDW), ... -
Selection for high spike fertility index increases genetic progress in grain yield and stability in bread wheat
(Springer Netherlands, 2018-07-18)Spike fertility index (SF) has been proposed as a promising trait to be used as a selection criterion in wheat breeding programs aimed at increasing grain yield, but no actual evidence of its successful application has ... -
Wheat spike fertility : inheritance and relationship with spike yield components in early generations
(2015)In wheat, grain number is considered as the product of spike dry weight (SDW) and the number of grains per unit of SDW, that is an indicator of spike fertility (SF). The aim of this study was to determine the heritability ...
