متن کاملBeef cattle performance and forage characteristics of continuous, 6-paddock, and 11-paddock grazing systems.
Heifer performance, diet composition, and forage composition were compared during rotational and continuous grazing of mixed pasture (alfalfa, tall fescue, orchardgrass). One hundred eighteen yearling heifers were used to compare the three grazing systems during 2 yr. Treatments included continuous (CONT), 6-paddock rotational (6-PADD), and 11-paddock rotational grazing (11-PADD). Rotational pa...
متن کاملPredicting grass dry matter intake, milk yield and milk fat and protein yield of spring calving grazing dairy cows during the grazing season.
Predicting the grass dry matter intake (GDMI), milk yield (MY) or milk fat and protein yield (milk solids yield (MSY)) of the grazing dairy herd is difficult. Decisions with regard to grazing management are based on guesstimates of the GDMI of the herd, yet GDMI is a critical factor influencing MY and MSY. A data set containing animal, sward, grazing management and concentrate supplementation v...
متن کامل14~s. 42-Paddock Rotational Grazing: Forage Quality
Research was initiated at the Texas Experimental Ranch by 1981 to quantify the effects of 2 livestock densities on forage quality in a rotational grazing (RG) treatment. Livestock densities evabmted were equivalent to 14 and 42-paddock RG treatments. Baseline data were collected in 1981 from 3 adjacent 30-ha paddocks in a 465_ha, M-paddock, ceil designed RG treatment stocked at a rate of 3.6 ha...
