Comparison Of Domestic Fresh And Frozen And Imported Frozen Goat Meat, Jeffrey Cole Denis Gregorie Jan 2016

Comparison Of Domestic Fresh And Frozen And Imported Frozen Goat Meat, Jeffrey Cole Denis Gregorie

LSU Master's Theses

The objective of this research was to determine differences in carcass evaluation, yield, and meat quality from representative fresh domestic (FSD), frozen domestic (FZD), and frozen imported Australian (FIA) goat carcass sides (n=30 from each source). The U.S. carcasses were split into sides and the right side frozen and stored for 6 weeks. Left sides were fabricated into standardized primal cuts. After frozen storage, right sides and FIA carcasses were thawed for 3 days at 4°C. Three experiments were conducted on the carcass traits and meat yields, quality differences in leg cut, and differences in loin and racks across freezing …

Integrated Methods For Controlling Gastrointestinal Nematode Infections In Ewes And Lambs, Sarah Tammy Nicole Keeton Jan 2016

Integrated Methods For Controlling Gastrointestinal Nematode Infections In Ewes And Lambs, Sarah Tammy Nicole Keeton

LSU Doctoral Dissertations

Gastrointestinal nematode (GIN) parasites cause extensive damage to small ruminants, and Haemonchus contortus is a major concern to production worldwide. With the development of GIN resistance to anthelmintics, alternative strategies for control are needed. The major component of this study compared two strategies for effect on animal health and changes in GIN population. One flock of ewes and lambs (Strategy 1, S1) employed targeted selective treatment (TST) with an anthelmintic based on FAMACHA score, and one flock (Strategy 2, S2) employed sericea lespedeza (SL) supplement feeding and TST with copper oxide wire particles (COWP) based on FAMACHA score. S1 ewes/lambs …

Effect Of Increasing Levels Of Dietary Zinc (Zn), Manganese (Mn), And Copper (Cu) From Organic And Inorganic Sources On Egg Quality And Egg Zn, Mn, And Cu Content In Laying Hens, Nancy Katherine Rubio Zapata Jan 2016

Effect Of Increasing Levels Of Dietary Zinc (Zn), Manganese (Mn), And Copper (Cu) From Organic And Inorganic Sources On Egg Quality And Egg Zn, Mn, And Cu Content In Laying Hens, Nancy Katherine Rubio Zapata

LSU Master's Theses

Feeding laying hens or broiler breeder hens organic sources of trace minerals can improve egg quality, especially as related to shell quality. The objectives of this research were to evaluate the effect of increasing laying hen dietary zinc (Zn) levels on the content of Zn and other minerals in eggs (boron (Bo), iron (Fe), and calcium (Ca)), and to evaluate the effect of feeding increasing Zn, manganese (Mn) and copper (Cu) levels from inorganic (ITM) and organic (OTM) sources on egg quality and yolk content of Zn, Mn, and Cu. In the first experiment, a total of 64 (48 weeks …

Vitrification Of Immature And Mature Bovine Oocytes, Paige T. Hardin Jan 2016

Vitrification Of Immature And Mature Bovine Oocytes, Paige T. Hardin

LSU Master's Theses

Vitrification is the latest technique used in cryopreservation, the ability to utilize this method with oocytes and embryos has become a valuable system. Vitrification has been successful with bovine embryos and oocytes but is far from optimal. Following cryopreservation storage discarding embryos can cause ethical issues, and mature oocytes have fragile organelles that can be detrimentally affected by ice crystal formation during freezing. Immature oocytes have not formed some of these temperature sensitive microfilaments and can circumvent these detrimental effects. The common intracellular cryoprotective agents are dimethyl sulfoxide, glycerol and ethylene glycol. Different combination of these agents have been reported …

Effects Of Calf Starter Composition And Mixing Method On Growth And Rumen Health In Young Dairy Calves, Ruth Marisol Orellana Rivas Jan 2016

Effects Of Calf Starter Composition And Mixing Method On Growth And Rumen Health In Young Dairy Calves, Ruth Marisol Orellana Rivas

LSU Master's Theses

Twenty-four male Holstein calves (BW = 38.78 ± 7.26 Kg) were used to evaluate the effects of commercially available or farm mixed starter on animal performance, blood metabolites, and rumen health. Calves were randomly assigned to one of two treatments which included: commercial calf starter (minimum 20% CP; CCS) and starter of similar nutrient content but hand mixed on farm (FMS). Calves were offered treatments ad libitum on days 4 through 84. Milk replacer (MR) was offered beginning on day 4. On day 42, MR was reduced to once daily to decrease intake by 50%. On day 49 calves were …

The Evaluation Of Eprinomectin (Longrange®) On Long-Term Parasitic Infection In Nursing Calves During Summer Grazing®, Lyndsea D. Seibert Jan 2016

The Evaluation Of Eprinomectin (Longrange®) On Long-Term Parasitic Infection In Nursing Calves During Summer Grazing®, Lyndsea D. Seibert

LSU Master's Theses

One of the most significant threats to the well-being and performance of grazing livestock are gastrointestinal nematode (GIN) parasitic infections. Allowing a large GIN burden to manifest can cause a significant cost in terms of productivity in grazing cattle. Beef producers commonly rely greatly on the efficacy of broad-spectrum anthelmintics, to not only kill resident worms but to also prevent the establishment of ingested infective stage larvae (L3) for a period following treatment. Eprinomectin (LONGRANGE®, E-LR) is the first extended-release injectable cattle dewormer that claims to provide cattle producers season-long persistent parasite control for 100 to 150 d in a …

The Effect Of Sericea Lespedeza (Lespedeza Cuneata) On Eimeria Spp. Infection In Broiler Chickens, Long Nghi Trinh Jan 2016

The Effect Of Sericea Lespedeza (Lespedeza Cuneata) On Eimeria Spp. Infection In Broiler Chickens, Long Nghi Trinh

LSU Master's Theses

Parasites cause considerable economic losses in all fields of agriculture. In the poultry industry, coccidia infections are of major significance costing billions of dollars every year. Research on condensed tannins (CT) has been shown to be effective against various parasites such as gastrointestinal nematodes and Eimeria spp. in small ruminants. This study tested the effects of the CT containing forage, sericea lespedeza (SL), on broiler chickens infected with live Eimeria spp. oocysts. In Study 1, 300 Ross 708 broiler chicks were divided into 6 groups (negative control, positive control w/BioCox, 0% SL, 5% SL, 10% SL, 15% SL). In Study …
