Proanthocyanidins From Hedysarum, Lotus And Onobrychis Spp. Growing In Sardinia And Sicily And Their Antioxidant Activity, A. Tava, M. G. De Benedetto, D. Tedesco, G. Di Miceli, G. Piluzza

IGC Proceedings (1997-2023)

Proanthocyanidins (PA), or condensed tannins, are a class of natural polyphenolic compounds, occurring in numerous plant species, including a number of economically significant forage legumes. These compounds are polymers of flavan-3-ols, and typically contain from 2 to 20 units. Their biological significance is still being debated and, in recent years, a great deal of attention has been focused on their role in ruminant nutrition. Evidence has indicated that PA, in a moderate concentration (0.5-5% DM), may have considerable importance in protecting dietary proteins against microbial degradation in the rumen, and in preventing bloat.

Leucaena Production In Arid Botswana, F. P. Wandera, M. Karachi, S. Mangope, B. M. Lefofe

IGC Proceedings (1997-2023)

The value of browse species as a source of nitrogen for grazing animals is restricted to wet seasons, with protein deficiencies being experienced by September (in dry winter season) in Southern Africa (Moleele 1998). This is when highly productive planted browse species would become useful to supplement the protein diet requirement of grazing animals (Morris & Du Toit 1998). Further, browse species can provide partly for protein requirement of intensive production systems, such as in feedlots and dairies. This paper reports work on the introduction and screening of Leucaena for Botswana conditions.
