Population Status And Characteristics Of Macrhybopsis Gelida, Platygobio Gracilis And Rhinichthys Cataractae In The Missouri River Basin, Selena J. Werdon

Electronic Theses and Dissertations

Few sturgeon chub (Macrhybopsis gelida: Cyprinidae) have been collected in the last decade, therefore their status, habitat selection and morphology were investigated at 172 previous collection sites. Data on two ecologically similar species, Platygobio gracilis and Rhinichthys cataractae, were also collected. Macrhvbopsis gelida were collected at 28 sites on the Powder River (n = 158) in Wyoming and Montana, and at one site on the Yellowstone River (n = 1) in Montana. Age-I, Age-II and Age-III M. gelida were collected. Specimens were 37 to 95 mm in total length. Macrhvbopsis gelida were ripe in mid-June, at water temperatures of 18.3-22. …

Impacts Of Types On Feed And Market Requirements, Donald L. Boggs

South Dakota Beef Seedstock Symposium, 1991

So you want to make them bigger! Or, do you want to add some milk to your cow herd? Improvements in these and other traits offer opportunities to increase production through higher weaning weights. However, the increased outputs are accompanied by increased feed and management inputs. Available research indicates that the increased production may or may not outweigh the increased inputs. Mature cow size and level of milk production are typically the factors considered when changes in cattle type are discussed. Numerous research studies have been conducted to evaluate the effects of these factors on biological and economic efficiency. In …

Current Status Of National Cattle Evaluation Programs For Carcass Traits, Larry Benyshek

South Dakota Beef Seedstock Symposium, 1991

At present, diet conscious consumers are exerting considerable pressure on the beef industry. Consumers continually indicate they are concerned about, and in fact, will not tolerate fat associated with red meat products (Breidenstein, 1988). This has resulted in many retailers trimming various cuts of beef to 1/8 inch of subcutaneous fat and in some cases a complete trimming of fat. It is probably conservative to estimate the industry produces an excess of 500 million pounds of fat each year from those carcasses with a yield grade above two. This excess fat represents the nutritional energy in more than a million …

Computations Associated With National Beef Cattle Evaluation Programs, Larry Benyshek

South Dakota Beef Seedstock Symposium, 1991

In 1971-72 the first U.S. National Sire Summary was published by a beef cattle breed association. At that time the idea of extending beef performance records into a national progeny testing program was indeed revolutionary. Until 1972, truly accurate comparisons of bulls could only be made within a herd-year-season contemporary group. The first and subsequent National Sire Summaries compared bulls across herds and/or generations.

Calving Difficulty In Beef Cattle: Part I, Harlan D. Ritchie, Peter T. Anderson

South Dakota Beef Seedstock Symposium, 1991

Calving difficulty (dystocia) can increase calf losses, cow mortality, and veterinary and labor costs, as well as delay return to estrus, and lower conception rates. In two studies at the U.S. Meat Animal Research Center (MARC), Clay Center, Nebraska, calf losses within 24 hours of birth averaged 4 percent for those born with little or no assistance compared to 16 percent for those requiring assistance. Calf mortality increased by a 0.35 percent per pound increase in birth weight. In a Hereford herd at the U.S. Livestock and Range Research Station. Miles City, Montana, 57 percent of all calf losses were …

Calving Difficulty In Beef Cattle: Part Ii, Harlan D. Ritchie, Peter T. Anderson

South Dakota Beef Seedstock Symposium, 1991

Many cattlemen believe reducing dietary energy during late pregnancy will decrease fetal size resulting in improved calving ease, whereas increasing energy will increase fetal size leading to a higher incidence of dystocia. Generally speaking, research has shown that lowering the energy allowance will decrease birth weight but will not significantly reduce dystocia. At MARC, Hereford and Angus 2-year-old heifers were fed three levels of energy (10.8, 13.7 or 17 .0 lb TDN/head/day) for 90 days prior to calving. Increasing the level of dietary energy resulted in increased birth weight but not increased dystocia; in fact, the incidence of calving difficulty …

Which Cows Are More Efficient, D. M. Marshall

South Dakota Beef Seedstock Symposium, 1991

On the surface, the topic of cow efficiency may seem to be primarily of importance to commercial cow-calf producers. The topic is also of importance to seedstock producers, because the primary purpose of the seedstock industry is to provide genetic resources for the commercial industry. It is critical that seedstock producers develop a good understanding of the challenges faced by commercial producers in order to provide the best possible services. Feed costs for the cow herd represent the single largest expense in producing retail beef. The proportion of total energy utilized in beef production that is required to support the …

Beef Cattle National Genetic Evaluation Programs, Larry Benyshek

South Dakota Beef Seedstock Symposium, 1991

Selection alters the frequency of genes in a population (breed) affecting a particular characteristic. Population genetic change is difficult for breeders to understand because they deal with individuals when making selection decisions and in their merchandising programs. Nevertheless, breeds (populations) which practice intense selection for characteristics of economic importance to the cattle industry will change genetically and eventually be the successful populations because they will leave the most progeny in the next generation. The genetic improvement of a population (breed) cannot overlook the individual because the individual, if selected, is the vehicle containing the genes which are to be passed …

Replacement Beef Heifer Economics, D. M. Feuz

South Dakota Beef Report, 1991

The nutritional management of weaned heifer calves affects not only the conception rate of yearling heifers but also their subsequent conception rate as 2-year-old cows and the weight of their first weaned calf. The costs involved in raising the replacement heifer and the value of cull heifers, 2-year-old cull cows and weaned first calves all need to be considered when determining the least cost method of raising replacement heifers. 'The effects of raising replacement heifers to prebreeding weights of 50% 62.5% and 70% of expected mature weight are evaluated from an economic perspective. If replacement heifers are only evaluated for …

Factors Affecting Weaning Weight Production, T. B. Goehring, D. M. Marshall, D. L. Boggs

South Dakota Beef Report, 1991

Weaning weight records from a commercial cow herd were statistically analyzed to demonstrate suspected sources of variation in weaning weight. Data from first-calf heifers and mature cows (3 to 9 year olds) were analyzed separately. For every one day increase in calf age at weaning, weaning weight was increased by 1.65 and 1.76 Ib for first-calf heifers and mature cows, respectively. For every 1 percentage point increase in MPPA of the cow, weaning weight was increased by 4.5 Ib. A 10% advantage in weaning weights and weight per day of age (WDA) was observed in steers over heifers. A 3 …

Chaps Summary For South Dakota, 1990, D. L. Boggs

South Dakota Beef Report, 1991

Calving distribution and calf performance data were summarized from the CHAPS (Cow Herd Appraisal of Performance Software) analyses of 61 South Dakota cow herds. CHAPS uses standard beef cow weaning weight records to calculate adjusted 205-day weights and ratios, keep lifetime production records on cows, calculate Most Probable Producing Ability estimates for cows, produce a sire summary and analyze production according to cow age and 21 -day calving periods. The 1990 summary represents 6,771 calves for an average of 110 cows per herd. The average actual birth and weaning weights were 82.2 and 523.2 Ib, respectively, with the average age …

Implant Strategies For Yearling Steers, R. H. Pritchard, M. A. Robbins

South Dakota Beef Report, 1991

Various implant strategies were compared in heavy yearling steers fed for 98 days. Implant treatments included control (nonimplanted), 722 (72 mg zeranol), 36TBA (36 mg zeranol plus 140 mg trenbolone acetate [TBA]), 72TBA (72 mg zeranol plus TBA) and ETBA (20 mg estradiol-200 mg progesterone plus TBA). The 72-mg zeranol dosage represents two implants in one site. Combinations of implants were administered, one in each ear. Implanting increased (P<.05) ADG and DM1 and decreased (P<.05) feed/gain values. Among implanted steers, no differences (P>.10) in ADG or DM1 were observed. Feed/gain was lower (P< .05) for zeranol-TBA combinations than the 72-mg zeranol treatment. Carcasses were heavier and rib eye area was greater (P<.05) in the 72TBA than 36TBA treatment. Kidney-pelvic-heart fat was lower (P<.05) when the ETBA combination was used.

Effect Of Inoculants On High Moisture Corn Fermentation Characteristics And Cattle Performance, C. P. Birkelo, D. Sorenson

South Dakota Beef Report, 1991

High moisture corn was ensiled untreated (treatment 1) or treated with one of three different inoculants (treatment 2 = lactobacillus; treatment 3 = lactobacillus + streptococcus; treatment4 = lactobacillus + serratia), each at two moisture levels (27.2% and 22.4%). lnoculant effects on fermentation were moisture dependent. The pH, acetate concentrations and dry matter losses were generally lower and lactate concentrations higher due to inoculation at 27.2% moisture. Overall, treatment 3 was somewhat more effective than treatments 2 or 4. Inoculation effects were generally less at 22.4% moisture. lnoculant effects on soluble N were small and probably of little nutritional importance. …

Substitution Of Rolled Barley For Whole Shelled Corn In Finishing Diets For Steers, R. H. Pritchard, M. A. Robbins

South Dakota Beef Report, 1991

Rolled barley was substituted for 0, 25, 50, 75 or 100% of the whole shelled corn in finishing diets fed to steers for 84 days. Increasing barley substitution resulted in a linear (P=.12) decrease in ADG and a quadratic (P<.05) decrease in DM1 with no effect on feed conversion. At the termination of the study, barley substitution caused a linear reduction in carcass weight (P<.01) and dressing percent (P<.01). The 100% substitution of barley for corn reduced (Pc.05) the percentage of carcasses grading choice. Dietary net energy values calculated from steer weights, gain and feed intake increased linearly (P<.10) as barley content of the diets increased, possibly reflecting positive associative effects. Published energy values for barley may not be suitable for least cost pricing in all feeding situations.

Grain Sources And Roughage Levels For Limited Feeding Backgrounding Programs, R. H. Pritchard, M. A. Robbins

South Dakota Beef Report, 1991

The effects of grain source and roughage level in limited intake feeding programs were evaluated in 622-lb steer calves. Supplemented diets were based on high moisture ear corn (HMEC), whole shelled corn (WSC) + hay to provide similar NDF to the HMEC diet, HMEC diet containing 10% hay and the WSC + hay diet formulated to contain NDF similar to HMEC + hay. Steer calves were blocked by weight and fed to achieve 2.2 Ib ADG for a 52-day period. Steers fed HMEC had higher (P<.01) ADG and lower (P<.01) feed/gain than WSC fed steers. Low crude protein in the hay source caused lower (P<.01) crude protein in WSC diets. Lower crude protein intake could have limited steer growth. NE utilization appeared more efficient (P<.05) for heavy weight block steers, reflecting NRC equation low sensitivity to modest differences in frame size. Roughage level did not affect performance and did not interact with grain source.
