2013 Beef Cattle and Range Research Report

File Troff document Full Report
The complete 2013 Beef Cattle and Range Research Report (72 pages).
File Introduction
Welcome messages from Ken Grafton, VP for Agricultural Affairs, and Chris Boerboom, NDSU Extension Service director (1 page).
File Corn stover and distillers grains for lactating drylot beef cows
This project evaluated the use of corn stover and distillers grains as the primary ingredients in lactating beef cow diets (3 pages).
File text/texmacs Effects of natural service and artificial insemination breeding systems on calving characteristics and weaning weights
A similar proportion of females exposed to estrous synchronization (ES) and artificial insemination (AI) became pregnant during the breeding season, compared with females mated during a natural service (NS) breeding system. Females in a breeding system that included ES and AI calved earlier in the calving season, compared with females mated with natural service, and a weaning weight advantage was observed in AI calves born within the first 21 days of the calving season, compared with NS calves born within the first 21 days of the calving season (3 pages).
File Maternal nutrient restriction followed by realimentation during early to midgestation on mammary gland development in beef cows
The objective of this study was to examine the effects of early to midgestation maternal nutrient restriction followed by realimentation on mammary gland development in beef cows (4 pages).
File Troff document Drylot vs. pasture beef cow/calf production: Three-year progress report
This study compares drylot feeding of lactating beef cows and calves with conventional pasture-based beef cow-calf production (4 pages).
File ECMAScript program An evaluation of Cellulo-Gest supplement to enhance forage digestibility and improve performance of growing calves
The objective of this study was to evaluate the effectiveness of a new feed enzyme additive product marketed to improve forage digestion (3 pages).
File Management strategies for summer-fed growing cattle: Effects of dietary protein levels and the use of bedding to alleviate heat stress on animal performance
The objective of this study was to evaluate the effects of higher protein diets and the use of corn stover as bedding to alleviate heat stress on the performance of summer-fed growing beef steers (3 pages).
File Effects of pen bedding and feeding high-crude protein diets on manure composition and feedlot pen surface temperature
The objective of this study was to investigate the effect of two dietary protein levels (12 and 16 percent) fed to beef cattle in pens with and without bedding on pen surface temperature and feedlot manure characteristics (4 pages).
File Distillers grains support equal steer performance in finishing diets with reciprocal levels of corn and barley
Reciprocal levels of corn and barley (0, 33, 67 and 100 percent) were fed with 25 percent distillers grain in growing and finishing diets. Steer performance and carcass quality traits were not affected, except the 67 and 100 percent barley diets were more efficient. Eighty-one percent of carcasses with corn in the diet and 63 percent of steers fed 100 percent barley graded Choice or better. Based on equal feed cost per pound of gain, a bushel of barley is valued at 95 percent of corn (4 pages).
File Influence of feed restriction and feeding time to growing calves on growth performance and feeding behavior
The objectives of this research were to determine the effects of limit-feeding and feeding time (daytime, nighttime, or half daytime and nighttime) on growth performance and feeding behavior of growing calves fed a corn-silage and hay-based backgrounding diet (3 pages).
File Pancreatic enzyme activity in high- vs. low-efficiency steers
The objective of this study was to determine if pancreatic mass or pancreatic digestive enzyme activity differs between steers of high and low efficiency (2 pages).
File text/texmacs Management strategies for summer-finished feeder cattle: Effects of dietary protein levels and use of bedding to alleviate heat stress on animal performance and carcass traits
The objective of this study was to evaluate the effects of higher protein diets and the use of corn stover as bedding to alleviate heat stress on the performance and carcass traits of summer-finished beef steers (4 pages).
File Consequence of two grazing systems before feedlot entry on yearling steer grazing and feedlot performance, carcass traits, tenderness and sensory panel response, and net return
The objective of this research was to examine the consequence of two extensive grazing systems for yearling steers based on perennial grasses or a combination of perennial grasses and annual forages before feedlot entry and to compare system net return to conventional feedlot finishing (4 pages).
File Finishing beef cattle on totally mixed and self-fed rations
The objective of this study was to evaluate self-fed rations compared with a totally mixed ration fed daily for finishing beef calves. Treatments consisted of two self-fed rations and one totally mixed ration (TMR) (4 pages).
File Effects of artificial insemination and natural service breeding systems on steer progeny backgrounding performance
The objective of this study was to determine the backgrounding performance of calves born early or late in the calving season and from breeding systems that incorporated artificial insemination (AI) or relied solely on natural service (3 pages).
File Discovering value in North Dakota calves: Dakota Feeder Calf Show feedout project XII, 2012-13
The Dakota Feeder Calf Show feedout project assists cattle producers in identifying cattle with superior growth and carcass characteristics. The spread in average profitability between the top and bottom five herds was $91.95 per head (3 pages).
File Effects of dietary forage concentration in finishing diets on growth and carcass characteristics of steers
The objective of this study was to evaluate the effect of feeding different levels of forage during the finishing phase of beef production (4 pages).
File Influence of dry-rolled corn processing and increasing dried corn distillers grains plus solubles inclusion for finishing cattle on growth performance and feeding behavior
The objectives of this study were to determine the effect of the degree of dry-rolled corn processing (coarse vs. fine; 2.68 vs. 1.46 centimeters [cm], or a bit smaller than 1/16 and 7/64 inch) and dried corn distillers grains plus solubles (DDGS; 20 vs. 40 percent) on feed intake, average daily gain, gain efficiency, carcass characteristics and feeding behavior in steers fed finishing diets. Feeding 40 percent DDGS improved feed efficiency, while corn processing and increasing the DDGS altered feeding and ruminating behavior (4 pages).
File The 2012 North Dakota Beef Industry Survey: Yesterday, Today and Into the Future
A survey was conducted during the spring of 2012 to determine how current beef producers perceive the future direction of the industry, determine attitudes regarding methods of enhancing farm/ranch profitability, and determine how our educational programs can evolve to meet the future needs of North Dakota beef producers (11 pages).
