Vegetation in the study area (10 ha) consisted mainly of buffelgrass (70% of covered area) and shrubs such as blackbrush (Acacia rigidula), pale verde (Cercidium macrum) and cenizo (Leucophyllum texanum), Shrubs comprised about 27% of the covered area. From January through December 1989, five 3-year-old castrated male lambs (Pelibuey X Rambouillet), weighing about 39 kg, were used to determine monthly total fecal output. Feces were collected during 4 days, after a 5 day adjustment period. The in vitro organic matter digestibility (IVOMD) was determined using esophageal extrusa samples collected from six esophageally fistulated male lambs. Differences (P &lt; 0.05) were found in OM intake (OMI) among months (annual mean, 818.6 g day). In general, lambs consumed more OM during May, June and July. Digestible energy (DE) intake was different (P &lt; 0.05) among months. Annual mean was 1436 kcal DE per day. Lambs consumed more DE during May, and least during February. Crude protein intake was highest (P &lt; 0.05) during July (189.7 g day) and lowest in January (90.1 g day). Neutral detergent fiber intake (NDFI) was also dissimilar (P &lt; 0.05) among sampling periods, the highest NDFI being in July (974.3 g per day) and the lowest in the winter months. Acid detergent fiber intake of lambs followed a similar pattern to that of NDFI. Macro minerals consumed by lambs (K, Ca, Mg and Na) were in general higher (P &lt; 0.05) during the summer months compared with other months. Trace minerals (especially Cu and Fe, Zn and Mn) consumed by lambs also varied seasonally. In general, the results of this study indicate that only during the summer months do lambs consume nutrients that meet or exceed their requirements.</style></abstract><accession-num><style face="normal" font="default" size="100%">ISI:A1995RG06600004</style></accession-num><notes><style face="normal" font="default" size="100%">Rg066Times Cited:10Cited References Count:0</style></notes><auth-address><style face="normal" font="default" size="100%">Ramirez, RgUniv Autonoma Nuevo Leon,Fac Med Vet &amp; Zootecn,Apartado Postal 142,Surcursal F,San Nicolas Garzas 66451,Nuevo Leon,MexicoUniv Autonoma Nuevo Leon,Fac Med Vet &amp; Zootecn,Apartado Postal 142,Surcursal F,San Nicolas Garzas 66451,Nuevo Leon,MexicoUniv Autonoma Nuevo Leon,Fac Agron,San Nicolas Garzas 66451,Nuevo Leon,Mexico</style></auth-address></record></records></xml>
