Pen Space Allocations And Pelleting Of Swine Diets, Mike Brumm

Nebraska Swine Reports

An experiment was conducted to determine whether an interaction exists between pen space allocation (14 versus 19 pigs per pen in 8 x 14 ft pens) and physical form of the diet (meal versus pellet) in a fully slatted facility. There were no interactions between diet form and pen space allocation for daily gain, feed intake or feed conversion efficiency. Pigs fed pelleted diets had a 2.3 percent improvement in daily gain and a 7.9 percent improvement in feed efficiency. Although pigs housed 14-per-pen grew faster than those housed 19-per-pen with no difference in feed conversion efficiency, pigs in the …

Consequences Of Differing Wool Growth Rates On Staple Strength Of Merino Wethers With Divergent Staple Strengths, A. C. Schlink, G. Mata, R. M. Lewis

Department of Animal Science: Faculty Publications

An experiment was conducted to determine the effects of dietary protein intake after a period of weight loss on the wool components of staple strength for sheep with a history of low or high staple strength (18.0 vs 34 Nlktex). After being fed to lose 15% of their liveweight over 10 weeks, sheep within each staple strength group were assigned in equal numbers to either a low or high protein diet designed to re-gain initialliveweight in 8 weeks. Liveweight, feed intakes and the growth, fibre diameter and fibre length characteristics of wool were measured at regular intervals. After the weight …

Effect Of Winter Gain On Summer Rate Of Gain And Finishing Performance Of Yearling Steers, Dale Downs, Galen E. Erickson, Don C. Adams, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

The effect of winter rate of gain on subsequent grazing and finishing performance was evaluated using 80 medium- framed steers. During the winter period, steers were fed to achieve gains of approximately .7 (low gain; 40 head) or 1.7 lb/day (high gain; 40 head). Warm-season Sandhills range was grazed by 20 low-gain and 20 high-gain steers, while the other 40 grazed bromegrass pasture from May to September. Both low- and high-gain cattle grazing brome pasture gained slower than those grazing sandhills range. During summer grazing, low-gain cattle gained faster than high-gain cattle, but compensated for only 19.9% (sandhills) and 18.7% …

Feather Meal As A Source Of Sulfur Amino Acids For Growing Steers, Mark Klemesrud, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

One-hundred twenty individually fed steer calves were used to evaluate feather meal as a source of sulfur amino acids. Treatment proteins included a urea control and meat and bone meal (6.4% of dietary DM) plus 0, 1, or 2% feather meal with incremental levels of rumen protected methionine. Adding feather meal to meat and bone meal resulted in a linear increase in gain. Likewise, rumen-protected methionine also improved gain. These results indicate feather meal can provide a portion of the sulfur amino acids lacking in meat and bone meal. However, additional methionine may further improve performance.

Use Of The Nrc Model For Evaluating Nutrient Balances Of Grazing Beef Cattle, Greg Lardy, Don C. Adams, Terry J. Klopfenstein, Dennis R. Brink

Nebraska Beef Cattle Reports

Research conducted at the Gudmundsen Sandhills Laboratory evaluated the National Research Council Beef Cattle Nutrient Requirements Model. Equations describing seasonal variability in CP, IVOMD, escape protein and degradable intake protein of native Sandhills range and subirrigated meadow were developed. Estimates of TDN and protein degradability for feedstuffs commonly used by Nebraska cow-calf producers are given. The NRC Model generally predicted nutrient balances in agreement with research trials. Microbial efficiency is lower for less-digestible forages. The NRC model is useful for evaluating grazed diets when accurate estimates of protein degradability, digestibility and intake are available.

Summer And Fall Forage Grazing Combinations: Five-Year Summary, Drew Shain, Terry J. Klopfenstein, D. J. Jordon, Rick Stock

Nebraska Beef Cattle Reports

A five-year study using British-breed crossbred cattle included slaughter breakeven analysis and evaluated the effect of grazing alternative summer and fall forages on beef production systems. Grazed summer and fall forage combinations included continuous brome and combinations of brome, warm-season grasses, alfalfa, sudangrass, red clover, native Sandhills range, turnips, rye and cornstalks. The most consistent improvement in summer grazing gain and most desirable slaughter breakeven costs were observed in cattle grazing brome and warm-season grasses or brome and Sandhills range. A reduction in slaughter breakeven cost by grazing fall forages was observed in years with adequate moisture for forage growth. …

Effect Of Energy Source And Escape Protein On Receiving And Finishing Performance And Health Of Calves, R. A. Mccoy, Rick Stock, Terry J. Klopfenstein, D. H. Shain, M. J. Klemesrud

Department of Animal Science: Faculty Publications

Two receiving and two finishing trials evaluated energy source and escape protein supplementation for calves. In receiving Trial 1, 398 calves (257 ± 24 kg BW) were used in a 2 x 2 factorial arrangement of treatments. Energy sources were dryrolled corn (DRC) and wet corn gluten feed (WCGF); each was fed without or with supplemental escape protein (EP). Calves fed WCGF gained slower ( P < .05) and consumed less DM ( P < .01) than calves fed DRC. Feed efficiency improved ( P < .10) with EP supplementation. In finishing Trial 1, 240 calves (305 ± 21 kg BW) were used. The arrangement of treatments was the same as in receiving Trial 1. Calves fed DRC/WCGF tended ( P = .15) to be more efficient and consumed less DM ( P < .05) than calves fed DRC. In receiving Trial 2, 315 calves (252 ± 23 kg BW) were fed diets similar to those fed in receiving Trial 1. Calves fed WCGF consumed less DM ( P < .01), gained similarly ( P > .15), and were more efficient ( P < .10) than calves fed DRC. In finishing Trial 2, 320 calves (298 ± 23 kg BW) were fed diets containing DRC, DRC/WCGF, high-moisture corn (HMC), HMC/WCGF, and DRC/HMC; each was fed without or with supplemental EP. An energy source ´ protein supplement interaction was detected for gain ( P < .05) and efficiency ( P < .01). Results suggest that WCGF has a NE_g greater than DRC in receiving diets and a NE_g similar to that of DRC but lower than that of HMC in finishing diets.

Solvent-Extracted Germ Meal For Receiving Calves, Daniel Herold, Mark Klemesrud, Terry J. Klopfenstein, Todd Milton, Rick Stock

Nebraska Beef Cattle Reports

This study evaluated solvent-extracted germ meal as a dietary ingredient for receiving calves. Treatments were 7% of dry matter as either corn bran or solvent-extracted germ meal in 55% concentrate diets. Average daily gain, dry matter intake and feed to gain ratio were not influenced by treatment. Dry matter offered for the first 7 days calves were in the feedlot also did not differ due to treatment. Both dry matter consumption and calf performance indicated solvent-extracted germ meal can replace up to 7% corn bran in the diet without influencing either dry matter intake or performance.

Predator Urines As Chemical Barriers To White-Tailed Deer, Jerrold L. Belant, Thomas W. Seamans, Laura A. Tyson

Vertebrate Pest Conference Proceedings: 18th (1998)

The authors assessed whether bobcat (Lynx rufus) or coyote (Canis latrans) urine could reduce white-tailed deer (Odocoileus virginianus) use of established feeding areas or trails. A four-week experiment evaluating deer use of eight feeding stations, four each with coyote or bobcat urine was conducted at a 2,200 ha fenced facility in northern Ohio with high deer densities (38/km²). At this same facility, the authors also monitored deer use of four trails where coyote urine was applied. For both experiments, urine was placed in holders positioned at ground level within 2 m of …

Effect Of Degradable Intake Protein Level On Finishing Cattle Performance And Ruminal Metabolism, D. H. Shain, Rick Stock, Terry J. Klopfenstein, D. W. Herold

Department of Animal Science: Faculty Publications

Two finishing trials and a metabolism trial were conducted to evaluate level of supplemental degradable intake (crude) protein (DIP) in finishing diets on cattle performance, carcass characteristics, and ruminal metabolism. Finishing trials were conducted in two consecutive years using 128 crossbred yearling steers (BW = 343 ± 5 kg, Trial 1) and 176 crossbred yearling steers (BW = 375 ± 4 kg, Trial 2) in a randomized complete block design. Steers were fed dry-rolled corn diets containing urea at 0, .88, 1.34, or 1.96% (DM basis). No differences in DMI, daily gain, or feed efficiency were noted among steers receiving …

Complementary Responses Between Feather Meal And Poultry By-Product Meal With Or Without Ruminally Protected Methionine And Lysine In Growing Calves, M. J. Klemesrud, Terry J. Klopfenstein, Austin Lewis

Department of Animal Science: Faculty Publications

We evaluated feather meal (FTH) and poultry by-product meal (PBM) as complementary protein sources for growing calves. In a replicated 84-d growth trial, individually fed steer calves (n = 120; 252 ± 24 kg) were supplemented with urea or with graded levels of soybean meal (SBM), FTH, PBM, or 2/3 FTH:1/3 PBM (CP basis). Protein efficiency, calculated as gain above the urea control vs natural protein intake using the slope-ratio technique, was greater for FTH than for SBM, PBM, and 2/3 FTH:1/3 PBM ( P < .10). Addition of ruminally protected methionine and lysine did not affect protein efficiency ( P > .30) for FTH, PBM, or 2/3 FTH:1/3 PBM. Even though true protein digestibility in the …

Effect Of Acute Treatment With Progesterone On The Timing And Synchrony Of Ovulation In Bos Indicus Heifers Treated With A Norgestomet Implant For 17 Days, J. Cavalieri, J. E. Kinder, L. A. Fitzpatrick

Department of Animal Science: Faculty Publications

The aim of the present study was to develop a treatment protocol for the precise synchronization of oestrus that would avoid the development of persistent dominant ovarian follicles. Bos indicus heifers, in which oestrous cycles had been presynchronized, were allocated randomly, according to the day of their oestrous cycle, to one of five treatment groups. All heifers received a subcutaneous ear implant containing 3 mg of norgestomet for 17 days starting on day 0 and an injection of an analogue of prostaglandin F_2α on days 0 and 4. Heifers in group 1 (control group; n = 7) received no …

Variances Of Direct Genetic Effects, Maternal Genetic Effects, And Cytoplasmic Inheritance Effects For Milk Yield, Fat Yield, And Fat Percentage, L. G. Albuquerque, Jeffrey F. Keown, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Milk yield, fat yield, and fat percentage during the first three lactations were studied using New York Holsteins that were milked twice daily over a 305-d, mature equivalent lactation. Those data were used to estimate variances from direct and maternal genetic effects, cytoplasmic effects, sire by herd interaction, and cow permanent environmental effects. Cytoplasmic line was traced to the last female ancestor using DHI records from 1950 through 1991. Records were 138,869 lactations of 68,063 cows calving from 1980 through 1991. Ten random samples were based on herd code. Samples averaged 4926 dams and 2026 cytoplasmic lines. Model also included …

A Tale Of Two Chickens: Exploring The Social And Economic Implications Of Our Food Choices, Laura Bainbridge

Presidential Scholars Theses (1990 – 2006)

A century ago chicken was considered a luxury item. In fact, people would eat steak or lobster when they could not afford chicken and ladies' magazines advised on how to substitute veal for chicken in recipes (Gordon, 1996). In 1928, President Hoover promised "a chicken in every pot", but it was not until the 1960's that the poultry industry really took off. Today, there are 15 chickens in every pot; the average American consumes 71.8 pounds of broiler meat annually (Oberholtzer, 1997). Where does all of this chicken come from? Who grows the chicken we eat and how do they …

Effect Of Summer Grazing On Crude Protein And Digestibility Of Winter Diets Of Cattle In The Nebraska Sandhills, Dale Downs, Don C. Adams, Terry J. Klopfenstein, Walter H. Schacht, Patrick E. Reece

Nebraska Beef Cattle Reports

Twenty-one pastures (three pastures/ treatment) were used in a two-year study to determine the effects of summer grazing on winter diet quality of Sandhills range. Summer grazing treatments consisted of no summer grazing (control) and June or July grazing at three stocking rates. After summer grazing, pastures were then diet sampled using esophageally fistulated cows in November, January and March following summer treatments. Year and sampling date had a significant effect on CP and IVDMD of winter range diets, whereas summer grazing treatments did not have a large impact.

Cull Dry Edible Beans In Growing Calf Rations, Ivan G. Rush, Burt Weichenthal, Brad Van Pelt

Nebraska Beef Cattle Reports

Including cull dry edible beans into diets for steer calves in two yearly trials produced slightly different results. In the first year, calculated net energy levels were higher in diets with 5 or 10% dry beans and daily gains were equal or better than for the no-bean diets. In the second year, with equal net energy values in rations containing 0, 7.5 or 15% dry beans, daily gains and feed intake decreased linearly with dry bean additions. Feed efficiency was improved as bean level increased.

Heartworm And Lungworms In Illinois' Canids And Their Possible Effect On Coyote Condition And Reproduction, David G. Gregory

Masters Theses

This study focuses on the prevalence of heartworm and lungworms in Illinois' canid species, and the effect that they may have on condition (body weight, kidney fat, marrow fat) and reproduction (placental scars) on coyote populations. A total of 1,150 coyotes (Canis latrans), 2,269 domestic dogs, 47 red foxes (Vulpes vulpes), and 2 gray foxes (Urocyon cinereoargenteus) were examined. Prevalence of heartworms (Dirofilaria immitis) averaged 17.8% in coyotes, 3.0% in domestic dogs, 2.0% in red foxes, and 0% in gray foxes. Domestic dogs not receiving any type of prophylactic treatment had a higher prevalence (12.5%) of heartworms than dogs on …

Future Of International Markets – Beef Cattle, Norman L. Dalsted

Range Beef Cow Symposium

As cattle producers are slowly working their way through the downturn in the current "infamous" cattle cycle what will the next century bring. At the turn of the last century the cattle industry was in its infancy relative to the position it currently holds in the U.S. agricultural sector. Some experts often refer to the cattle business as a mature, well established entity indicating that cattle producers, processors, and packers represent an established, stable component of the agricultural sector. However, the dynamics of this industry are anything but stable to the individual cattle producer. Thus, as we enter the 21st …

Selection Emphasis For Carcass Traits, John Crouch

Range Beef Cow Symposium

Carcass evaluation for the Angus breed was conceived by Dr. Richard Willham and co-researchers at Iowa State University in 1972 as part of the original sire evaluation program. This very structured program consisted of random mating schemes throughout several commercial herds using the same set of bulls. These sires were later referred to as the original set of reference sires for the Angus breed and served as foundation benchmarks for future evaluation.

This structured sire evaluation program is still in place. While it has been refined and altered by Dr. Doyle Wilson to fit today's needs, the basic principles are …

Bovine Viral Diarrhea, Hana Van Campen

Range Beef Cow Symposium

Bovine viral diarrhea (BVD) is a common viral infection of cattle worldwide. The viruses responsible for BVD are classified as pestiviruses, a group of viruses that includes BVDV type I and type II, Border disease virus of sheep and hog cholera virus. Although BVD was first recognized as a disease of cattle 50 years ago, the genetics and epidemiology of BVD viruses have only been well-described in the last 10 years. These scientific advances have increased the accuracy of diagnostic testing for BVD and clarified the diseases caused by BVD viruses.

BVD is a confusing topic because the viruses cause …
