Alfalfa in dry stress conditions cannot grow optimally. Drought inhibits growth and reduces alfalfa production many cultivation systems. Plants breeding with gamma-ray irradiation vitro selection using PEG found somaclonal variants adapted to well drought conditions. This study aims determine the type of mutation best morphology mutants resulting from gamma were sub-cultured vitro. cultured med...

Three experiments were conducted to determine the effect of receiving diets containing alfalfa meal and certain feed additives on performance of comingled feeder pigs transported 900 to 1,100 km. In Exp. 1, the inclusion of 9.4% dehydrated alfalfa meal in receiving diets for 2 wk resulted in no difference (P greater than .1) in gain or feed conversion from purchase to market compared with pigs ...

Second-stage juveniles (J2) of races 1 and 2 of Meloidogyne chiiwoodi and M. hapla readily penetrated roots of Thor alfalfa and Columbian tomato seedlings; however, few individuals of M. chitwoodi race 1 were able to establish feeding sites and mature on alfalfa. Histopathological studies indicate that J2 of race 1 either failed to initiate feeding sites or they caused cell enlargement without ...

Three Latin square trials, with 20 (two trials) or 24 (one trial) multiparous lactating Holstein cows (four in each trial with ruminal cannulae), compared the feeding value of red clover and alfalfa silages harvested over 3 yr. Overall, the forages contained similar amounts of neutral detergent fiber and acid detergent fiber; however, red clover silage contained more hemicellulose, less ash and...

The objective of this study was to compare utilization of red clover (Trifolium pratense L.) and alfalfa (Medicago sativa L.) by lactating dairy cows. Red clover and alfalfa were harvested and conserved as silage at two maturities in 2 consecutive yr. Each year, diets containing experimental forages and supplemental grain were fed to 16 multiparous Holstein cows in early lactation in a replicat...

The alfalfa weevil, Hypera postica (Gyllenhal), is a serious, yet sporadic defoliator of alfalfa, Medicago sativa L., in Nebraska. A 2-yr study was conducted in 2005 and 2006 to test for variation in degree-day requirements by location in eastern Nebraska. Sampling took place along a latitudinal gradient in three regions of eastern Nebraska. Three fields were sampled in each region during the 2...

the effect of different levels of alfalfa hay and corn silage, in early lactation diet, on milk production and on milk components in holstein cows was investigated. fifteen holstein cows (37 ±10 dim) were taken in a completely randomized design experiment, lasting for 9 weeks. three levels of hay and corn silage namely: 1) 10% alfalfa -30% silage corn (diet 1), 2) 20% alfalfa -20% silage corn (...

We evaluated the effect of wet corn gluten feed and a novel product containing raw soybean hulls and corn steep liquor on performance in lactating dairy cows. Forty-six multiparous Holstein cows were used in a randomized incomplete block design. Cows were housed in tie stalls for the first 13 weeks of lactation and moved to group pens for the remainder of the study. Cows were blocked by calving...

We report the complete genome sequence of a viral pathogen detected in alfalfa samples from Sudan and provisionally named alfalfa enamovirus 2 (AEV-2). Based on high nucleotide and amino acid identities, AEV-2 represents a strain of a newly discovered alfalfa enamovirus 1 that has only been described in Argentina.
