The objective of this research was to evaluate of three grazing systems (GS) with elephant grass (EG), Italian ryegrass (IR) + spontaneous growing species (SGS); EG + IR + SGS + forage peanut (FP); and EG + IR + SGS + red clover (RC), during the winter and summer periods in rotational grazing with dairy cattle. Experimental design was completely randomized with three treatments, two replicates with repeated measures. Lactating Holstein cows receiving 1% BW-daily feed supplement with concentrate were used in the evaluation. Eight grazing cycles were performed during the experimental period. The values of pre forage mass and stocking rate were 2.52, 2.60 and 2.99 t ha-1 and 2.64, 2.77 and 3.14 animal unit ha-1, respectively for GS. Samples of forage were collected by hand-plucking technique to analyze the crude protein (CP), neutral detergent fiber (NDF), in situ dry matter digestibility (ISDMD), in situ organic matter digestibility (ISOMD) of forage present between rows of elephant grass, in the rows of elephant grass and the legumes. Higher value of CP, ISOMD and lower of NDF were observed for the grazing systems mixed with legumes forage.

Three grazing systems with Coastcross-1 bermuda grass (CC) + 100 kg N ha-1 year-1 + common vetch; CC + 100 kg N ha-1 year-1 + arrowleaf clover; and CC + 200 kg N ha-1 year-1 were evaluated. Thirteen grazing cycles were performed during the experimental period (313 days), with two, five, four and two cycles respectively in winter, spring, summer and fall. Lactating Holstein cows were used in the evaluation. Daily accumulation rate, forage production, rate of forage disappearance, agronomic intake, grazing efficiency, herbage allowance and stocking rate were evaluated. Mean rates of forage yield and stocking rate were 20.8; 17.6 and 19.7 t DM ha-1 and 7.0; 6.8 to 6.8 animal units ha-1 day-1 for the respective forage systems. The mixture Coastcross-1 plus common vetch, fertilized with 100 kg N ha-1 year-1 and Coastcross-1 fertilized with 200 kg N ha-1 year-1 provided greater productivity and better distribution of forage throughout the seasons.

The availability of high quality forage, especially during the dry season remains a major challenge to ruminant livestock production in Nigeria and many parts of West Africa. This study was conducted to evaluate forage yield and nutritive quality of haulm from selected dual purpose cowpea (Vigna unguiculata L. Walp.) cultivars in the humid rain forest zone of Nigeria. The forage and pod yields of twenty cultivars were evaluated at the Teaching and Research Farm of the Federal University of Technology, Owerri, Imo State, Nigeria. Subsequently, five dual-purpose cultivars, namely IT04K-334-2, IT07K-293-3, IT04K-194-3, IT04K-405-5, IT06K-147-2, were selected based on forage and pod yields from previous trial, for determination of chemical and fibre compositions. The results revealed significant (P<0.05) differences in pod and forage yields among the twenty cowpea cultivars, with yields ranging from 0-1.5 t ha-1 and 0.1-4.5 t ha-1 for pod and forage, respectively. Cultivars IT07K-293-3, IT04K-405-5, IT06K-147-2, IT07K-194-3, IT04K-334-2, IT04K-267-8 and IT04K-339-1 recorded the highest fodder yields of at least 2715 t ha-1, with crude protein contents ranging from 10.49% in IT07K-194-3 to 13 .57 % in IT04K-405-5. Cultivars IT07K-194-3, IT07K-293-3, IT07K-220-1-9, IT06K-147-2, IT07K-187-55IT04K-332-1 recorded the highest pod yields (>700 t ha-1). There were significant (P<0.05) differences in crude protein, ether extract and non-fibre carbohydrates (NFC) contents among five cultivars selected from the top ten high yielding cultivars, based on mean ranking score. These selected cultivars are recommended as dual-purpose cowpea for the humid forest zone.

AbstractThe effects of growing pinto peanut mixed with elephant grass-based pastures are still little known. The aim of the current research was to evaluate the performance of herbage yield, nutritive value of forage and animal responses to levels of pinto peanut forage mass mixed with elephant grass in low-input systems. Three grazing systems were evaluated: (i) elephant grass-based (control); (ii) pinto peanut, low-density forage yield (63 g/kg of dry matter – DM) + elephant grass; and (iii) pinto peanut, high-density dry matter forage yield (206 g/kg DM) + elephant grass. The experimental design was completely randomized with the three treatments (grazing systems) and three replicates (paddocks) in split-plot grazing cycles. Forage samples were collected to evaluate the pasture and animal responses. Leaf blades of elephant grass and the other companion grasses of pinto peanut were collected to analyse the crude protein, in vitro digestible organic matter and total digestible nutrients. The pinto peanut, high-density dry matter forage yield + elephant grass treatment was found to give the best results in terms of herbage yield, forage intake and stocking rate, as well as having higher crude protein contents for both elephant grass and the other grasses, followed by pinto peanut with low-density forage yield + elephant grass and finally elephant grass alone. Better results were found with the grass–legume system for pasture and animal responses.

The grazing of cereal and canola crops during winter is an increasing component of grazing systems in southern Australia. The capacity of such crops to meet the requirements of young livestock and reproducing animals for sodium (Na), magnesium (Mg), calcium (Ca) and potassium (K) is reviewed. The growth responses of young stock to Na and/or Mg supplements when grazing wheat are discussed. These responses differ from ‘literature expectation' in that they are rapid in onset and involve no clinical signs. We demonstrate that more insight about the variability in supplement response, both between and between crops species, is obtained when mineral contents are viewed from the perspective of their frequency distributions, rather than their mean values. The pivotal importance of high K concentration, low Na and the resultant K:Na ratio of forage is stressed, as is the interaction of these minerals in relation to Mg absorption. We also present frequency distributions for a range of mineral indices that ‘capture' mineral interactions, including the ‘tetany index', forage K: (Na+Mg) ratio and dietary cation–anion difference. It is concluded that the last two indices warrant a much closer investigation. Possible effects of forage aluminium and organic acid contents are briefly discussed; these also deserve closer examination. As research in this area continues, it would be prudent to provide Na and/or Mg supplements for livestock grazing wheat and possibly oats and barley, and calcium supplements for livestock grazing oats or for reproducing animals grazing all three cereals.
