in order to evaluate effects of plant density and planting date on quality properties of grass pea (lathyrus sativus l.), a factorial experiment was conducted during 2008, based on complete randomized block design with four replications in research farm of faculty of agriculture, the university of birjand, birjand, iran. plants were planted at march 5 and 20, and apr 3, with 30, 40, 50 and 60 p...

TROSZYŃSKA A., CISKA E. (2002): Phenolic compounds of seed coats of white and coloured varieties of pea (Pisum sativum L.) and their total antioxidant activity. Czech J. Food Sci., 20: 15–22. The purpose of this study was to compare the composition and contents of phenolic acids and condensed tannin in the seed coats of white and coloured varieties of pea and to examine the antioxidant properti...

the effect of grape pomace (vitis vinifera) and in oak leaf (quercus libani) tannins by three runs of in vitro gas production on the organic matter digestibility (omd) and in situ dry matter (dm) and crude protein (cp) disappearance were studied in four sheeps. polyethylene glycol (peg) was used to deactivate the tannins. in vitro gas production was recorded at 2, 4, 6, 8, 12, 48, 72, 96 and 12...

Ingestion of small amounts of condensed tannin (CT) by ruminants can prevent bloat, improve nitrogen retention, and reduce excretion of urea, a precursor of ammonia and the greenhouse gas nitrous oxide. Because grasses and many forbs don’t contain CT, it is desirable to find a reliable way to have ruminant livestock ingest small amounts of CT when they consume high-quality forage. Putting CT in...

The condensed tannin (CT) content of eight shrub species (Cytisus purgans, Cytisus scoparius, Genista florida, Genista occidentalis, Calluna vulgaris, Erica arborea, Erica australis and Juniperus communis) from a grazing mountain area of northern Spain was analysed and related to various indicators of nutritive value. Chemical composition, in vitro gas production, OM degradation and true DM dig...

grass pea(lathyrus sativus l.) is a crop used for both animal and human consumption. recently, icarda has developed new grass pea lines with the objectives of improving its yield potential and adaptability. the objective of this study was to investigate grain and forage yields stability of several icarda released grass pea lines by using additive main effects and multiplicative interactions (am...

Ingestion of small amounts of condensed tannin (CT) by ruminants can produce valuable outcomes such as improved nitrogen use and reduced bloating, methane output, and gastrointestinal parasitism. However, many grasses and forbs contain little if any CT. The specific types of CT vary in plants and can have somewhat different effects on ruminants. Individual ruminants can respond differently to C...

This study was performed to investigate how smoke solution affects dry matter loss, crude protein (CP) and toxic compound ODAP contents of grass pea in hydroponic media during seven days period. Three doses solutions (1, 5 10%, V: V) by diluting with tap water were applied seeds as priming agent, used a control (0%). The experiment arranged according the split-plot design three replications. Co...
