Information is needed on rain effects on yield and quality of legume and legume-grass hays. A field study was conducted on a Plano silt loam soil (fine-silty, mixed, mesic, Typic Argiudoll) to evaluate rain effects on the yield and chemical composition of hays from pure swards of alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.), and birdsfoot trefoil (Lotus corniculatus L.) and mixtures with smooth bromegrass (Bromus inermis Leyss.). Plots for the factorial experiment (each 1.1 by 7.6 m) were arranged in a split plot design with legume species and pure or mixed sward type combinations as main plots and wetting treatments as the sub plots with four replicates. Wetting treatments consisted of field drying to 750 g dry matter (DM)/kg of total mass (TM) or more without rain or exposure to rain or artificial wetting during drying. Samples were collected just after cutting and after hay curing for quality analysis. Rain reduced the proportion of leaf by 109 and 151 gfkg for alfalfa and birdsfoot trefoil, respectively, but did not affect red clover leaf content. Rain increased DM loss by as much as 154 g/kg (pure alfalfa) but did not affect DM loss for the birdsfoot trefoil-grass mixture. Legume-grass hays generally had more neutral detergent fiber (NDF) and lower N and in vitro dry matter disappearance (IVDMD) concentrations than pure legume hay. Rain or wetting reduced IVDMD by from 13 gfkg (birdsfoot trefoil-grass) to 64 gfkg (alfalfa). Except for Ca, which was reduced in some cases, rain or wetting did not affect mineral concentrations in dry hay. The presence of grass in the sward provided consistent advantage in bay drying only for red clover. Rainfall increased DM losses during hay curing except for the grass-dominated birdsfoot trefoil mixture. Rain or wetting reduced bay quality by reducing IVDMD and increasing NDF concentration. Nitrogen, P, K, and Mg concentrations were not greatly affected by rain or wetting. --~------------Additional index words: Alfalfa, Medicago sativa L., Red clover, Trifolium pratense L., Birdsfoot trefoil, Lotus corniculatus L., Nitrogen, Neutral detergent fiber, In vitro dry matter disappearance, Hay curing. -, Contribution of the Dep. of Agron., Univ. of Wisconsin, Madison, WI 53706.

“…A number of workers have reported DM losses of about 3% per day during wilting (4,15,18,42,43,44,67), although much smaller losses (67,80) and larger losses (67,68) have also been reported. Other studies have shown no net change in DM during wilting (25) or DM gains (45,69).…”

The rates of respiration in cut swards of Lolium perenne (S321) were measured while drying under simulated field conditions, the purpose of the experiment being to assess the extent of respiratory losses which can occur in the process of haymaking.Respiration measurements were made on the grass at different moisture contents during the drying process and also at different stages of growth. The results show that hoth the moisture content and the age of the grass had a significant infiuence on respiratory rates, consequently these factors can he expected to infiuence the DM losses which occur during haymaking. It was estimated that respiratory losses could amount to, at most, hetween 1-28 and 0 26 kg/100 kg DM, depending on the stage of growth at which the grass is cut
