"THE SIGNIFICANCE OF SILAGE PROTEIN DEGRADATION AND PLASMA AMINO ACID RATIOS IN THE CONTROL OF FOOD INTAKE BY LAMBS FED ENSILED AND FRESH ALFALFA."

Abstract:

Alfalfa (30% dry matter) was harvested with a particle length of 0.6 cm, conserved fresh (frozen) or as silage and fed to eight lambs during two 27-d periods. The ensiling process resulted in substantial degradation of lysine, threonine, histidine, arginine, tryptophan and tyrosine in the original herbage. Isoleucine, leucine and valine resisted degradation during ensilage. As a consequence of these changes, the ratios of tyrosine: large neutral amino acids and tyrosine: phenylalanine (TYR:LNAA and TYR:PHE) were markedly lower in ensiled compared to fresh alfalfa (0.035 vs. 0.051 and 0.235 vs.

Abstract:

Alfalfa and sainfoin are high-quality forages with different condensed tannins (CT) content, which can be affected by the stage of maturity. To study the effects of CT on fermentation parameters, three substrates (alfalfa, sainfoin, and sainfoin+PEG) at three stages of maturity were in vitro incubated for 72 h. Sainfoin had greater total polyphenol and CT contents than alfalfa. As maturity advanced, CT contents in sainfoin decreased (p < 0.05), except for the protein-bound CT fraction (p > 0.05). The total gas and methane production was affected neither by the substrate nor by the stage

Abstract:

Fresh produce, including salad, is increasingly implicated in foodborne outbreaks. Although studies have been carried out to detect specific human pathogens from fresh produce, the total bacterial community associated with fresh produce is poorly understood. In this study, we characterized the bacterial community associated with alfalfa sprouts, using a culture-independent method. Four retail-purchased alfalfa sprout samples were obtained from different producers, and the bacterial community associated with each sample was determined by 16S rDNA profiling.

Drought stress is a prevalent environmental stress that adversely affects agricultural industries worldwide. In this study, bacterial isolates, AFFR02 and Mj1212, showed tolerance to polyethylene glycol-induced (PEG) drought stress (approximately 15%) and possess strong phosphate-solubilizing capacity. Moreover, we investigated the plant growth attributes, chlorophyll content, and ion uptake in alfalfa plants (Medicago sativa L) inoculated with isolates AFFR02 and Mj1212 under drought stress. We observed that drought stress drastically affects alfalfa’s growth attributes: shoot length: SL (24.

Abstract:

Fertilization management is a key issue in plant nutrition to produce plants with good quality and quantity. Deproteinized leaf juice or brown juice (BJ) is a by-product during the isolation of leaf protein from biomass crops such as alfalfa. The idea of using BJ as a biostimulant fits well in the aspect of circular economy since BJ is currently a problematic issue of the leaf protein production approach. Fractionation of one-kilogram fresh biomass results in approximately 500 cm3 BJ. Due to fast spoil of fresh BJ, if left on room temperature, it is found that fermentation of fresh BJ using la

RGluc concentration was highest in the youngest leaves (>15 μg per g fresh weight) and oldest stem internode seg

Three alfalfa (Medicago sativa L.) cultivars differing in fall dormancy were examined for endogenous abscisic acid content in relation to fall dormancy. The alfalfa cultivars studied were 'Beaver' (dormant type), 'Lahonton' (semidormant type), and 'Moapa 69' (nondormant type). Alfalfa seedlings were grown in controlled-environment chambers set at a 16-h photoperiod (16 h light: 8 h dark) and 20:15 °C (light:dark) for 55 days. They were cut and then regrown under environmental conditions simulating summer and fall in western Canada. In leaf samples, the ABA level increased from about 200 in 3-w

The conversion of protein nitrogen (PN) to nonprotein nitrogen (NPN) in forages occurs rapidly and extensively during wilting and ensiling. The objectives of this study were to determine whether the amount of time between cutting and ensiling affects protein degradation in red clover (Trifolium pratense L.) and alfalfa (Medicago sativa L.) silage and to document pre- and post-ensiling characteristics of these two species.

Aerobic spoilage of silages occurs frequently and is undesirable because it reduces both its nutritive and hygienic quality. Silage inoculants containing heterofermentative lactic acid bacteria, like Lactobacillus buchneri, have already been proven to improve aerobic stability by augmented production of acetic acid, which inhibits yeasts. In this study, the effect of L. buchneri on fermentation characteristics and aerobic stability of alfalfa-ryegrass silage, red clover silage and maize silage was assessed using microsilos.

Chlorophyll in rumen fluid was higher on days when the alfalfa caused bloat, compared to days when bloat did not occur (P < 0.01). Chlorophyll was also higher in froth

The transgenic genotypes expressed the Lc gene at different levels when grown under high light conditions, resulting in anthocyanidin contents as high as 136 g g-1 DM.

Lactating cows require complete balanced rations to meet their high nutritional requirements and to maximize milk and milk fat production. Total mixed rations (TMR) were developed to meet these nutritional needs by thoroughly mixing necessary feedstuffs into a single ration; hence providing a balanced diet in each bite. However, the actual nutrient and fiber concentration consumed by cows can dramatically differ from that of the ration due to selective feeding. The objectives of this study were to 1) evaluate the palatability of alfalfa hay TMR and alfalfa baleage TMR and 2) determine the effe

SUMMARYThe aim of the current work was to investigate the possibility of modifying the existing mean stage by weight (MSW) system for evaluating the average development stage in alfalfa. The modification was performed with the aim of providing a simplified system that may be used to evaluate the alfalfa development stage and to predict its nutritive value for ruminants. The suggested modification consists of designating an MSW value on the basis of the fresh weight of all morphological stages in a fresh green plant, as opposed to the original method which is based on weighing all morphological
