Department of Animal Science: Faculty Publications

Crossbred Angus cow–calf pairs (n = 28 pairs) at the Central Grasslands Research Extension Center (Streeter, North Dakota) were used to evaluate an electronic feeder to monitor individual mineral intake and feeding behavior and their relationship with growth performance and liver mineral concentrations. Cows and calves were fitted with radio frequency identification ear tags that allowed access to an electronic feeder (SmartFeed system; C-Lock Inc., Rapid City, South Dakota) and were provided ad libitum minerals (Purina Wind and Rain Storm, Land O’Lakes, Inc., Arden Hills, MN). Mineral intake, number of visits, and duration at the feeder were recorded over …

Grazing System And Management For Goat Production, Steve Hart

Professional Agricultural Workers Journal

Abstract Grazing system management is for supplying inexpensive, adequate nutrition for the goat enterprise. This involves managing forages to facilitate dry matter production and managing grazing so forage quality is adequate and harvest efficiency is high while avoiding consuming internal parasites. Since nutrient costs are greatest for winter, the grazing system should be planned to provide some grazing during winter. The forage system should be managed to provide the greatest proportion of nutrients possible during kidding and lactation. The base forage species can be overseeded with cool-season or leguminous species to improve forage production, quality or the seasonal distribution of …

Year-Round Forage Production For Sustainable Goat Farming, Uma Karki

Professional Agricultural Workers Journal

Abstract

Goat farming in the U.S. is based on grazing lands. Forages available for grazing throughout most of the year are essential for supplying required nutrition for goats and minimizing production costs. Most goat farmers do not have pastures productive for an extended period. This situation results in poor performing animals and high production costs. Forage availability can improve by enhancing the productivity, quality, and production duration of pastures. The inclusion of browse species in grazing systems will also improve diet variety, minimize internal parasite problems, and better utilize the soil resources. Grazing opportunity can be extended by developing a …

Utilizing An Electronic Feeder To Measure Mineral And Energy Supplement Intake In Beef Heifers Grazing Native Range, Kacie L. Mccarthy, Sarah R. Underdahl, Michael Undi, Stephanie Becker, Carl R. Dahlen

Department of Animal Science: Faculty Publications

Introduction

Grasslands in the Northern Plains provide the primary forage source for ruminants throughout much of the year (Schauer et al., 2004). Supplementation practices are often necessary to maintain production and offset forage nutritive decline throughout the grazing season (Schauer et al., 2004; Cline et al., 2009). Typically, to maintain a targeted production level, energy and protein supplementations are used for grazing livestock (Caton and Dhuyvetter, 1997). For developing heifers consuming low-quality forages, inclusion of energy ingredients into supplements may be beneficial for growth and reproductive performance (Schillo et al., 1992; Ciccioli et al., 2005; Cappellozza et al., 2014). In …

Changes In Corn Residue Quality Throughout The Grazing Period And Effect Of Supplementation Of Calves Grazing Corn Residue, Amanda J. Burken

Department of Animal Science: Dissertations, Theses, and Student Research

Corn residue is an abundant feed source in Nebraska that can be utilized as an alternative winter feed. Calves were backgrounded on corn residue in order to determine gain and estimate forage intake when supplemented with distillers grains (DGS). Calves grazing the non-irrigated field gained more (1.03 kg/calf daily) when compared to those grazing the irrigated field (0.90 kg/calf daily; P < 0.01). In year 1, a quadratic effect for intake of DGS was present (P < 0.01) while year 2 observed a linear effect for increasing level of DGS (P < 0.01). The nutritional quality of corn residue was evaluated over time in order to determine changes in blade/sheath, cob, husk/shank and stem. Minimal changes in DM of the forage components occurred was grain reached 15.5% moisture. Digestibility of the blade/sheath declined linearly over time (P < 0.01) while the husk remained constant (P = 0.40). Cob digestibility decreased quadratically (P < 0.01) throughout the sampling period with few changes once grain reached 15.5% moisture. Differences observed in the digestibility of the blade/sheath were attributed to the effects of weathering. A third set of trials was conducted to evaluate the effects of by-product supplementation of calves grazing irrigated corn residue and supplemented with DGS or continuous access to lick tubs. The DGS treatment gained more (0.62 kg/calf daily) than the lick tub treatment (0.38 kg/calf daily; P < 0.01). Calves offered DGS consumed more supplement as a percentage of BW (0.52%) when compared with calves offered lick tubs (0.36%; P < 0.01) on a DM basis. Calves supplemented with DGS had a higher supplement efficiency (46.3% to 42.9%, DM basis) although no differences were present between treatments (P = 0.49). When analyzed on an OM basis, however, calves offered lick tubs had a numerically higher supplement efficiency (50.4%) in comparison to calves …

Two consecutive summer grazing studies were conducted to quantify the effect of supplementing cows with wet distillers grains (WDGS) mixed with low quality forage on 1) grazed forage intake and 2) cow and calf performance. During exp. 1, twenty-four three year old lactating cows rotationally grazed for 56 d and were assigned to one of three treatments: 1) the recommended stocking rate of 1.48 AUM/ha with no supplementation (CON1), 2) double the recommended stocking rate (2.96 AUM/ha) and supplemented 6.64 kg/hd daily of 45% grass hay and 55% WDGS (DM) to replace 50% of estimated total intake (SUP), and 3) …

Pilbara Steer Growth Evaluation : 1994 - 1996, Wayne Fletcher, Brian Mcintyre, Shane Cridland Dr, J L. James

Agriculture reports

Growth potential of steers in the Pilbara - a summary. The trial was conducted over a range of conditions on three locations. The pasture type at Wyloo, the Ashburton River frontage, which is regarded as one of the most productive pasture types in the area, combined with conservative stocking, a fresh paddock and excellent seasonal conditions during 1995, gives us an indication of the District's potential. In extrapolating any of these data to other cases, consideration must be given to adjustment base

Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan

Journal of the Department of Agriculture, Western Australia, Series 4

A recent Mt Barker experiment compared two systems of fodder conservation with continuous grazing, using two types of steers, at three stocking rates. Year-round performance, carcass composition, and resulting costs and returns per hectare were assessed.

Production per hectare was greatest from crossbred steers at the intermediate stocking rate with either type of fodder conservation.
