Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones
Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones
Animal Science Undergraduate Honors Theses
Abstract
Anthelmintic resistance (AR) urges alternatives to control gastrointestinal nematodes (GIN). Copper oxide wire particles (COWP) are more efficacious when used with other dewormers and little is known on efficacy of diatomaceous earth (DE) to control gastrointestinal parasites. The objective was to examine the effects of DE and COWP on GIN control. Katahdin lambs (n = 32; ~150 d of age; 25.0 ± 1.8 kg) were randomly assigned to receive: 1) DE fed at an estimated 2% dry matter intake (with the assumption of moderate consumption of bermudagrass forage and provided supplement), 2) 1g COWP, 3) both 2% DE and …
Evaluation Of Enzyme Effectiveness At Enhancing Fiber Digestion In Small Ruminants, Rachel Ranells
Evaluation Of Enzyme Effectiveness At Enhancing Fiber Digestion In Small Ruminants, Rachel Ranells
Animal Science Undergraduate Honors Theses
Feed costs account for up to 70% of total production costs making it vital that livestock producers maximize feed efficiency in a cost-effective manner (Bach, 2012). Producers often utilize feed additives to optimize nutrient absorption and increase productivity (McGrath et al., 2018). This study was conducted to determine the effects of an enzyme supplement containing Aspergillus niger and Aspergillus oryzae on dry matter (DM), organic matter (OM), neutral detergent fiber (NDF) and acid detergent fiber (ADF) intake and digestibility by lambs fed ad libitum diets of either alfalfa or bermudagrass hay. The study was set up in a 2 2 …
Predicting Kidding Date Using Prepartum Milk Calcium Concentrations And Comparing Kid Growth To Colostrum Quality In Goats, Justin Hamm
Animal Science Undergraduate Honors Theses
Abstract
Goats have a very long history with mankind and are commonly used as a nutritious red meat source around the world. The supply of goat meat in the United States does not meet the growing demand from ethnic consumers. This provides an economic opportunity in Arkansas agriculture because goats are uniquely adapted to the Ozark environment. There is a wide gap in caprine research which facilitated the conception of the study’s objectives to determine whether prepartum milk in goats showed a sudden rise in calcium levels within 24 to 48 hours of kidding and to ascertain whether an increased …

Predicting The Onset Of Parturition By Determining Calcium In Prepartum Milk Of Sheep, Lensey Watson
Animal Science Undergraduate Honors Theses
Multiple methods of pregnancy detection can be used in sheep production. The gestation period for sheep is usually between 144 and 150 days; however, depending on the breed and age of the ewes, this number can vary. A breeding marker, such as a breeding crayon, is used to detect when the ewe is bred by the ram, and the date the ewe will lamb is typically calculated based on an average 145-day gestation. Unfortunately, this method provides only a rough estimate of when the ewe could lamb. In addition, because sheep routinely give birth to multiples (twins, triplets, and, sometimes, …

Calcium And Magnesium Absorption And Retention By Growing Goats Offered Diets With Different Calcium Sources., Jennifer Long
Animal Science Undergraduate Honors Theses
Calcium addition is necessary in order to balance the high phosphorus concentrations that are characteristic of high-concentrate ruminant diets. However, calcium sources differ in their bioavailability. Our objective was to determine apparent Ca and Mg absorption and retention in goats offered diets containing different sources of Ca. Spanish-Boer goats (n=18; 19.6 ± 1.88 kg) were stratified by BW and sex and randomized to dietary treatments consisting of Purina Antlermax 16 containing either calcium carbonate (CC), Calmin (CM) or Milk Cal (MC). Goats were adapted to a control, corn-based high-concentrate diet on pasture and then moved to individual 1.0 × 1.5 …
