Effect Of Methionine Addition To A Urea-Grain Based Supplement On Digestibility Of Mature Prairie Grass Hay, P.A. Momont, R. J. Pruitt, R. H. Pritchard, P. S. Johnson

South Dakota Beef Report, 1989

A digestibility trial was conducted to determine the effect of methionine addition to a grain-urea based supplement on the digestibility of mature prairie hay. Ad libitum hay supplemented with .I Ib supplemental crude protein from either a (1) soybean meal, (2) methionine + urea-grain, (3) sulfur + urea-grain or (4) urea-grain supplement was fed to 20 Hampshire ram lambs. Dry matter, neutral detergent fiber and acid detergent fiber disappearances tended to be higher with methionine or sulfur-urea supplements over urea alone. Diet digestibilities between soybean meal, - methionine and sulfur treatments were similar. Methionine increased apparent nitrogen digestibility of the …

Effects Of Amino Acid And Branched-Chain Volatile Fatty Acid Additions On In Vitro Fermentation Of Dormant Range Grasses, P.A. Momont, R.J. Pruitt, R. H. Pritchard, B. J. Johnson Jan 1989

Effects Of Amino Acid And Branched-Chain Volatile Fatty Acid Additions On In Vitro Fermentation Of Dormant Range Grasses, P.A. Momont, R.J. Pruitt, R. H. Pritchard, B. J. Johnson

South Dakota Beef Report, 1989

Two-stage in vitro fermentation was used to screen five amino acids and three branched-chain volatile fatty acids as potential additions to a grain urea supplement for cows grazing dormant winter range. Urea addition alone increased dry matter and fiber digestibility of dormant cool season grasses. Methionine addition improved fiber digestibility and rate of fermentation of cool season grasses over urea alone. Compared to urea addition, the branched-chain volatile fatty acids did not increase dry matter or fiber disappearance or improve rate of fermentation of dormant range grasses. None of the buffer additions tested or urea increased digestibility of the dormant …

Alternate Day Supplementation Of High Escape Compared To Low Escape Protein Fed With Corn Stalks, R. M. Collins, R. H. Pritchard Jan 1989

Alternate Day Supplementation Of High Escape Compared To Low Escape Protein Fed With Corn Stalks, R. M. Collins, R. H. Pritchard

South Dakota Beef Report, 1989

A study was conducted using four ruminally fistulated wethers to compare ruminal fermentation characteristics of corn gluten meal (high escape) and soybean meal (low escape) supplements to corn stalks. Supplements were fed at 24 or 48-hour intervals. Ruminal ammonia nitrogen (RNH3-N) concentrations were affected (P<.05) by treatment and treatment by hour interactions occurred. Soybean meal fed at 48- hour intervals (SBM48) resulted in the highest mean and peak RNH3-N concentrations, as expected due to the quantity of rumen degradable protein fed. Soybean meal fed at 24-hour intervals (SBM24) caused higher (P<.05) RNH3-N concentration than corn gluten meal fed at 24-hour intervals (CGM24) but not CGM48. Total VFA concentrations averaged over time were not affected (P> .I0) by type of protein supplement. Treatment by hour interactions were observed (Pc.05) for total VFA, because SBM24 resulted in higher VFA concentrations at several points in the 48-hour sampling period. The ratios of acetate:propionate: butyrate were similar, 74:18:7, 74:18:7, 74:18:8 and 74:18:8 for SBM24, SBM48, CGM24 and CGM48, respectively. Ruminal fluid pH values were …

Frost Damaged, Immature Soybeans For Ruminant Diets, J.A. Loesche, R. H. Pritchard, J. M. Reecy Jan 1989

Frost Damaged, Immature Soybeans For Ruminant Diets, J.A. Loesche, R. H. Pritchard, J. M. Reecy

South Dakota Beef Report, 1989

The potential for including freeze damaged, immature soybeans (FDIS) into corn based diets for ruminant animals was evaluated in a series of experiments. No differences in feeding value were evident for FDlS and normal soybeans except due to oil content. Oil content of soybeans depressed dry matter and particularly fiber digestion of corn silage fed to lambs (Pe.05). Nitrogen digestion and retention were also reduced (Pe.10) by feeding raw soybeans. The effect on N utilization appeared to be due to trypsin inhibitor activity, since this did not occur when soybean meal + oil supplements were fed. Nitrogen, dry matter and …

Moderate Versus High Protein Diets For Finishing Yearling Steers, J.J. Wagner, R. Hansen Jan 1989

Moderate Versus High Protein Diets For Finishing Yearling Steers, J.J. Wagner, R. Hansen

South Dakota Beef Report, 1989

Sixty-four yearling crossbred steers (864 Ib) were utilized to study moderate versus high protein finishing diets. Diets were formulated to contain 11.25 or 12.25% crude protein on a dry matter basis. Differences observed for all performance and carcass traits were not significant. Steers on the 11.25 and 12.25% crude protein diets consumed 22.29 and 22.26 Ib dry matter per head daily, gained 2.83 and 2.90 Ib per head daily and required 7.91 and 7.69 Ib dry matter per pound of gain, respectively. Diets formulated to contain 11.25% crude protein appear adequate for finishing heavy yearlings.

Effect Of Late Season Protein And Energy Supplementation On Performance Of Yearling Steers Grazing Mixed Native Range Or Cool Season, Crested Wheatgrass Pastures, J.J. Wagner, P.S. Johnson, J. Cantrell

South Dakota Beef Report, 1989

Seventy-two yearling, black baldy steers were utilized in a grazing experiment to study the effect of late summer, early fall protein (2.33 Ib., 40% all natural, fed each Monday, Wednesday and Friday) or energy (4.4 Ib. corn fed daily) supplementation on average daily gain. Two pasture types, mixed native range and crested wheatgrass, were also examined. Cattle were purchased in May as part of a larger group and gained an average of 2.16 Ib. per head daily prior to initiation of the study on September 9, 1988. Average daily gain was significantly greater (P = .012) for cattle grazing crested …

Hydrolyzed Feather Meal Supplementation For Lactating Range Cows, P.A. Momont, R.J. Pruitt, J. Cantrell Jan 1989

Hydrolyzed Feather Meal Supplementation For Lactating Range Cows, P.A. Momont, R.J. Pruitt, J. Cantrell

South Dakota Beef Report, 1989

Sixty-eight cows calving in March and April grazing dormant winter range were used to evaluate hydrolyzed feather meal a protein supplement during early lactation. Within a week after calving cows were fed either a soybean meal or feather meal-corn supplement that provided approximately .83 Ib. crude protein per cow daily. Cow weight and condition score changes from calving until early May and percentage of cows cycling at the beginning of the breeding season in early June were similar between supplement groups. Calf average daily gains from birth until May were not affected by supplement fed to cows. In this study, …

New Breeds - Are They For You?, Kreg Leymaster, Roman L. Hruska

South Dakota Sheep Field Day Proceedings and Research Reports, 1989

Sheep breeds differ greatly in levels of performance for economically important traits. Because the differences among breeds are genetic in nature, these differences can be exploited rapidly and cheaply to increase profits for sheep producers. While over 30 breeds exist in the U.S., there are foreign breeds that may fit into our sheep industry. A past example is the use of Finnsheep to improve reproductive performance in commercial flocks. There is a growing opportunity to import the most promising breeds throughout the world. If subsequent experimental evaluation documents the usefulness of imported breeds, these breeds to improve the efficiency of …

Effects Of Melanocyte Stimulating Hormone (Msh) On The Transformation Of Phaeo- To Eumelanogenesis In The Lethal Yellow Mouse (C57bl/6j;Ay/A), Alexander W. Van Amerongen Jan 1989

Effects Of Melanocyte Stimulating Hormone (Msh) On The Transformation Of Phaeo- To Eumelanogenesis In The Lethal Yellow Mouse (C57bl/6j;Ay/A), Alexander W. Van Amerongen

Electronic Theses and Dissertations

The objective of this study was to assess if· MSH induces in yellow (Ay/a) mice, a program of black melanin production that is identical in terms of melanosome structure and development to that of normal black (a/a) mice. Since there is a difference between melanosomes of the two genotypes, Ay/a and a/a, and MSH induces eumelanin production in phaeomelanin producing Ay/a melanocytes of the opportunity exists to narrow down and define the Ay/a effects on melanosomal parameters after MSH treatment. If there is any significant difference between Ay/a and a/a melanosomal parameters measured, these differences are due solely to the …

Wall Lake, South Dakota : A Case Study In Geographic Planning, Jane E. Van Hunnik Jan 1989

Wall Lake, South Dakota : A Case Study In Geographic Planning, Jane E. Van Hunnik

Electronic Theses and Dissertations

Wall Lake is a hypereutrophic (overenriched with nutrients) glacial lake similar in character to many other glacial lakes in South Dakota. As is the case with most glacial lakes, Wall Lake is naturally eutrophic (nutrient enriched) because of the nutrient rich loess which usually occurs in close proximity to glacial kettles and is mixed with nutrient rich glacial till. A hypereutrophic state occurs when additional nutrients are added to the lake by such sources as agricultural runoff, mixing of water with enriched sediments, and by wastewater systems. The result is the accelerated natural progression from lake, to wetland, to dry …

Fed And Fasting Nitrogen Metabolism By Lambs Fed A Semi-Purified Diet Supplemented With Urea Or Zein, K. F. Hoppe, R. H. Pritchard Jan 1989

Fed And Fasting Nitrogen Metabolism By Lambs Fed A Semi-Purified Diet Supplemented With Urea Or Zein, K. F. Hoppe, R. H. Pritchard

South Dakota Sheep Field Day Proceedings and Research Reports, 1989

Most finishing diets include corn as a primary energy source. If the finishing diet consists mostly of corn, a large proportion of the protein needed by the ruminant is supplied through corn protein. A protein in corn, zein, largely escapes ruminal degradation (60%) and the ungraded fraction is passed into the small intestine for digestion. Since urea and zein act differently in supplying proteins and amino acids to the small intestine of the ruminant, an evaluation of nitrogen retention in lambs was conducted. The objective of this study was to evaluate the effects of diet nitrogen change, time and fasting …
