(Texas A&M University. Libraries, 1982)Factors affecting egg production and hatching success of the copepod Acartia tonsa Dana were determined by measuring environmental variables and daily egg production of field collected females in the laboratory. During ...
-
(Texas A&M University. Libraries, 1993)Insecticides have been applied to cotton in combination with a variety of diluents and agrichemicals. Preliminary studies suggested that one agrichemical or diluent can improve, have no effect, or decrease insecticidal ...
-
(Texas A&M University. Libraries, 1983)Temporal and spatial use patterns of 2 South Texas feedlots by wintering blackbirds were examined. Economic impact associated with daily foraging was estimated. Effectiveness of 6 selected bird-damage control techniques ...
-
(Texas A&M University. Libraries, 1982)The U.S. cattle feeding/fed-beef economy will likely face a rapidly changing economic environment as a result of escalating energy and labor costs, population increases and interregional migrations, regional variations in ...
-
(Texas A&M University. Libraries, 1990)A study, using the prematurely weaned rat as an animal model for the pig, was undertaken to determine the effect of dietary cholesterol and carbohydrate source on small intestinal structure and function. Duodenal and jejunal ...
-
(Texas A&M University. Libraries, 1983)Laboratory studies were focused on developing feeds and feeding strategies for efficient postlarval and juvenile penaeid shrimp rearing through experimental manipulation of environmental factors and feed nutrient composition. ...
-
(Texas A&M University. Libraries, 1989)Growth studies were conducted with fingerling blue tilapia (Oreochromis aureus) to determine lysine and methionine requirements, and the cysteine replacement value for methionine. The fish were fed experimental diets ...
-
(Texas A&M University. Libraries, 1992)Nutrient delivery to aquatic larvae must be controlled before their nutrition can be critically studied. Conventional feed particles and microcapsules for larval shrimp have poor water stability and/or poor nutrient ...

Nutritional and physiological aspects of supplementing niacin and dietary fat in lactation rations (Texas A&M University. Libraries, 1986)Four studies were conducted to evaluate effects of supplemental niacin and dietary fat in lactation rations. In Experiment 1, 28 lactating Holstein cows were used to compare effects of niacin and whole cottonseed (WCS) on ...
-
(Texas A&M University. Libraries, 1993)The addition of menhaden oil (MO) to laying hen rations results in a significant increase in yolk omega-3 (n-3) fatty acid content. Due to proposed cardiovascular benefits associated with n-3 fatty acids, Americans have ...
-
(Texas A&M University. Libraries, 1987)Parameters were estimated for nonlinear growth curves for bulls of five straightbred and 20 crossbred breedtypes produced in two generations of a diallel. The primary intent of this study was to use the estimates obtained ...
-
(Texas A&M University. Libraries, 1982)Mature, ileal cannulated ponies were used to quantify partial and total tract nitrogen digestibility of forages, cereal grains and protein supplements. Feed, ileal, fecal and urinary nitrogen was determined and nutrient:chromic ...
-
(Texas A&M University. Libraries, 1984)Thirty mares were fed varying levels of protein during the last 90 days of gestation and the first 90 days of the subsequent lactation to determine the effect of protein intake on mare postpartum reproductive performance, ...
-
(Texas A&M University. Libraries, 1986)Twenty-four lactating Holstein cows offered diets containing (1) no buffer (control), (2) 1.8% potassium bicarbonate, (3) 1.2% potassium carbonate, or (4) 1.5% sodium bicarbonate in the concentrate, consumed more diet 3 ...
-
(Texas A&M University. Libraries, 1992)Data including actual measures and estimates of various performance and cost factors were collected from three commercial feedyards located in the Texas Panhandle. The effectiveness with which such performance and cost ...
-
(Texas A&M University. Libraries, 1980)Experiments were carried out in the summers of 1978 and 1979 in 12 outdoor plastic-lined circular wading pools (about 7 m('2) in area) at the Aquaculture Research Center of the Texas Agricultural Experiment Station near ...
-
(Texas A&M University. Libraries, 1990)Three experiments were conducted to determine quadratic growth functions based on cumulative protein and energy intake in broiler chickens during starter, grower, and finisher phases of feeding. Indian River male broiler ...
-
(Texas A&M University. Libraries, 1987)Two experiments were conducted to evaluate the potential of nonconventional diets with high protein to calorie ratios to limit abdominal fat in broilers. In experiment 1, 1,100 male and 900 female chicks were randomly ...
-
(Texas A&M University. Libraries, 1976)Restricting day length or feed consumption in winter-hatched Broad Breasted White turkeys were studied for their effects on reproductive performance. Turkey males were either full-fed and received 15, 12 or 8 hours of light ...
