Animal performance and carcass characteristics of Nellore young bulls fed coated or uncoated urea slaughtered at different weights R. Bras. Zootec.
Pazdiora,Raul Dirceu; Resende,Flávio Dutra de; Faria,Marcelo Henrique de; Siqueira,Gustavo Rezende; Almeida,Geraldo Benedito de Souza; Sampaio,Ricardo Linhares; Pacheco,Paulo Santana; Prietto,Murilo Sergio Rodrigues.
The objective of this study was to evaluate animal performance and carcass characteristics of 64 Nellore young bulls at 22 months of age finished in a feedlot and slaughtered at five body weights (350; 455; 485; 555 and 580 kg) fed diets containing coated or uncoated urea. The experimental design adopted was completely randomized, set in a 4 × 2 factorial arrangement, and for the variables assessed in the control animals, it was 5 × 2. No effect of interaction between slaughter weights and diets were observed, so the variables were analyzed separately, compared by polynomial contrasts and by the F test, respectively. The time animals remained in the feedlot to reach slaughter weights was 66, 88, 145 and 194 days. Average daily gain (ADG) showed quadratic...

Benefits of net feed intake in a large commercial feedlot AgEcon
Herd, Robert M.; Arthur, Paul F.; Dibley, K.; Mula, D.; Snelgar, T.; Thompson, J..
This experiment investigated the benefits of feeding steers bred from parents known to be of high genetic merit for feed efficiency (HE; midparent net feed intake-estimated breeding value (NFI-EBV) ≤-0.3kg/day), medium efficiency (ME: midparent NFI-EBV >-0.3 to 0.14 kg/day), or low efficiency (LE; midparent NFI-EBV ≥0.16kg/day). The steers were evaluated over a 251-day feeding period in a large commercial feedlot. Genetic superiority in NFI had a favourable impact on the commercial performance of Angus steers by reducing feed consumed with no adverse effect on final turnoff weight. Each HE steer consumed on average 2.60t of feed compared to 2.87t by the ME and LE steers, with no compromise in weight gain. The HE steers gained less subcutaneous ribfat...

Development and evaluation of models to estimate body chemical composition of young Nellore bulls R. Bras. Zootec.
Silva,Luiz Henrique Oliveira; Bonilha,Sarah Figueiredo Martins; Branco,Renata Helena; Cyrillo,Joslaine Noely dos Santos Gonçalves; Mercadante,Maria Eugênia Zerlotti.
ABSTRACT The objective of this study was to develop accurate regression equations to predict body composition of Nellore cattle using chemical composition of the 9th, 10th, and 11th ribs and to evaluate the models proposed by analyzing mean and linear bias. Sixty-seven Nellore bulls were slaughtered and slaughter body weight (SBW), hot carcass weight (HCW), and 9th-, 10th-, and 11th-rib-cut weight (RCW) were measured. Empty body composition was obtained after grinding, homogenizing, sampling, chemical analysis, and pooling (blood, skin, head + feet, viscera, and carcass). Chemical components were determined in rib cut, carcass, and empty body: protein (RCP, HCP, and EBP), fat (RCF, HCF, and EBF), ash (RCA, HCA, and EBA), and water (RCWt, HCWt, and EBWt)....

ECONOMIC EVALUATION OF WET CORN GLUTEN FEED IN BEEF FEEDLOT FINISHING AgEcon
Haugen, Ronald H.; Hughes, Harlan G..
An economic evaluation of wet corn gluten feed used in beef feedlot finishing was done. Data were from feeding trials at North Dakota State University. Four rations were analyzed at 0 percent, 28 percent, 56 percent, and 85 percent wet corn gluten based on dry matter intake. Data were entered into a computer model that integrated the feeding trial data with economic input and output prices. A typical feedlot example was used. Results indicated that the 56 percent ration was the most biologically efficient. A matrix of results can be shown for various corn prices, relative to wet corn gluten feed prices and quantities fed. Based on this study, wet corn gluten feed is priced competitively with other feed stuffs.

Estimation of a Multi-Input Multi-Output Model of Lot-Fed Beef Cattle in Australia AgEcon
Fleming, Pauline; Fleming, Euan M.; Griffith, Garry R.; Johnston, David.
Most analyses of technical efficiency and productivity focus on the activities of firms or institutions using inputs to produce outputs. In this paper, we report the results of an efficiency analysis that is couched in a different context. We analyse the efficiency with which physical characteristics of individual lot-fed Australian beef cattle are combined with conventional inputs to produce a final product with several attributes that consumers value. Data on 214 animals across seven breeds were used to estimate a stochastic input distance function with multiple inputs and multiple outputs. Estimates were obtained after controlling for differences between breeds, seasons and sex. Because of variations in feeding regimes for different markets, the data...

Ribeiro,Andressa Ferreira; Messana,Juliana Duarte; José Neto,Antônio; Fiorentini,Giovani; Berchielli,Telma Teresinha.
ABSTRACT The objectives of this study were to evaluate the effect of forages with different nutritional values - specifically, corn silage (CS), sugar cane (SC), and sugar cane bagasse (SB) - in diets with crude glycerin, on carcass traits, meat quality, and fatty acid profile, using young Nellore bulls finished in the feedlot. Thirty young Nellore bulls with an initial average body weight of 416.70±24.74 kg were randomly assigned to three treatments containing different sources of forage. The carcass traits and variables related to meat quality of the Nellore young bulls were not significantly influenced by different sources of forage in diets with crude glycerin. The yellow color index was significantly greater in the fat of animals fed corn silage....

ABSTRACT: Gossypol easily pairs with lysine side chains and enzymes involved in the cellular growth process. The effect of gossypol (a compound present in cotton co-products) in ruminant metabolism and meat quality is not yet clear. This study was undertaken in order to evaluate the effects of cotton co-products in lamb muscle proteome. Twenty-four Santa Inês ram lambs, 5-months old (20.6 ± 1.9 kg), were randomly assigned to four treatments: control (without cottonseed), whole cottonseed, cottonseed meal and high oil cottonseed meal. At 95 days into the experiment, lambs were slaughtered and samples from Longissimus dorsi were collected. Proteins were extracted and analyzed by 2-D electrophoresis. Spots showing a significant effect from the treatment (the...
