“…The high leaf-to-stem ratio of rhizoma peanut in our study may be attributed to good summer rainfall distribution in the years of the experiment which reduced senescence and leaf drop. Neutral-detergent fiber, ADF, lignin, and mineral concentrations in rhizoma peanut were similar to levels reported for peanut hay (Prine et al, 1981;Gelaye et al, 1990). Crude protein of rhizoma peanut varies with maturity of the harvested forage and ranges from 12 to 19% (Prine et al, 1981).…”

Limits of environmental adaptation of ‘Florigraze’ rhizoma peanut (Arachis glabrata Benth.), a high‐quality perennial warm‐season legume, have not been well defined. A field experiment compared yield and nutritive value of rhizoma peanut and alfalfa (Medicago sativa L.) in central Georgia on a Norfolk soil (fine‐loamy, siliceous, thermic Typic Kandiudults). Crude protein (CP), neutral‐detergent fiber (NDF), aciddetergent fiber (ADF), lignin, Ca, Mg, and P of total herbage, and dry matter (DM) yield and in vitro organic matter disappearance (IVOMD) of total herbage, leaf, and stem tissues were determined for three growing seasons. Annual DM yield of peanut and alfalfa averaged 7.6 and 11.8 Mg ha−1, respectively. In the first 2 yr, alfalfa outyielded rhizoma peanut, but there was no difference in yield in the third year. Leaf DM yield was higher for peanut than for alfalfa in the third year. Rhizoma peanut DM production occurred predominately during late summer and early autumn vs. spring for alfalfa. Rhizoma peanut total herbage DM was lower in CP and higher in Ca and Mg than that of alfalfa, but IVOMD was similar. Leaf IVOMD was higher for alfalfa than for rhizoma peanut, but IVOMD of peanut stems was equal to or higher than alfalfa stems. Rhizoma peanut has potential for central Georgia and other areas of the southern USA with a similar climate.

“…Gelaye et al . () observed BUN (20 mg dL −1 ) and glucose (67·7 mg dL −1 ) concentrations similar to the present study when dairy goats were offered ALF hay without grain supplementation. Turner and Neel () reported BUN levels similar to the present study when Boer‐crossbred goats were offered ALF hay in a feeding study.…”

“…Forage treatments were selected from species with known adaptation to the region. Alfalfa was selected because of its established reputation as an important forage legume (Hoveland, ) and because it has supported superior weight gains in meat goats offered hay (Gelaye et al ., ). Red clover was selected because of its high level of rumen‐undegraded protein (RUP), which has been associated with improved protein utilization (Jones et al ., ,b).…”

The experiment was conducted in 2005–2007 to evaluate weight performance, blood parameters associated with forage nutrient‐use and anaemia from gastrointestinal nematode (GIN) infection, and faecal egg count (FEC) patterns of meat‐goat kids finished on alfalfa (Medicago sativa L.; ALF); red clover/grass mixture (Trifolium pratense L.; RCG); and orchardgrass (Dactylis glomerata L; OGR) pastures. Forage mass, crude protein (CP) and total digestible nutrients (TDN) displayed complex interactions between treatment and time (P < 0·001) across the grazing seasons. Final body weight was greater for goats finished on ALF and RCG than on OGR, except in 2006 when ALF was greater than RCG or OGR. The TDN/CP ratios in forages and blood urea nitrogen concentrations in grazing goats were highly correlated (r = 0·99; P = 0·02) and suggested that animals were wasting forage protein. Faecal egg count was variable over the grazing season each year (date and treatment × date interaction; P < 0·001), but in general, FEC indicated that goat kids grazing ALF were less affected by GIN than kids grazing RCG or OGR. Research is needed to determine whether strategic energy supplementation would improve protein‐use efficiency and resilience to parasite infection when finishing meat goats on pastures managed for high forage nutritive value.

“…Previous work compared hays of perennial peanut and alfalfa, and although perennial peanut had a slightly lower crude protein concentration than alfalfa, the in situ rate of protein degradation was slower, indicating that the RUP of perennial peanut was greater than that of alfalfa . In a study by Gelaye et al ., however, comparing alfalfa, perennial peanut, or a combination of the two forages, nitrogen intake and excretion were not different among goats fed these diets, indicating the RUP was not different between alfalfa and perennial peanut . The presence of a low concentration of tannin could explain the inconsistent reports of reduced ruminal protein degradation of perennial peanut and low levels of tannins have been reported .…”
