Creep grazing and early weaning effects on cow and calf productivity.
One hundred fifty Simmental-Hereford cows and calves were used in a 3-yr study to evaluate three creep grazing treatments and an early weaning treatment on cow and calf performance during midsummer (July to September). Calves were approximately 150 d of age and averaged 178.6 kg when treatments were initiated. Tifleaf pearl millet (Pennisetum Americanum L. Leeke) was used as the forage for two ...
متن کاملAge of Weaning and Parasitism in Merino Lambs
Merino lambs born in September and October 1964 were weaned at 4, 6 and 11 weeks of age, at average liveweights of 9 kg, 12 kg, and 19 kg respectively, on to a pasture of phalaris and white clover. The lambs remaining with their mothers for 11 weeks showed the earliest onset of an appreciable worm infection which reached a peak in December about one month after weaning. Similar levels of infect...
متن کاملEffect of Dried Distillers Grains Supplementation on Calves Grazing Bermudagrass Pasture or Fed Low-Quality Hay
The objective of the following experiments was to examine the effect of dried distillers grains plus solubles (DDGS) supplementation of calves grazing bermudagrass (Cynodon dactylon) pasture during summer (Exp. 1) or fed lowquality tall fescue hay (Exp. 2, Festuca arundinacea) during winter months. In Exp. 1, a total of 36 steers (261 kg) were randomly assigned to one of nine 0.81-ha pastures r...
متن کاملIntake of High Producing Holstein Cows Grazing Pasture or Fed a Total Mixed Ration
(week 4). Intake was estimated in week 4 by dosing twice daily with 5 g Cr 2 O 3 for 10 days. Fecal samples were collected twice daily on days 7 to 11 of Cr 2 O 3 dosing, with pre-grazing pasture being sampled on days 6-10 of dosing. Fecal output, calculated from fecal chromium concentrations, and in vitro digestibility (IVDMD) were used to calculate intake (Parker et al. 1989). The intake of c...
