The effect of monensin in lactating beef cows in poor body condition receiving low levels of energy (Texas A&M University. Libraries, 1977)Two studies were conducted to determine if reproductive patterns or blood constituents could be altered by feeding monensin. In the first study the effects of monensin on weight gain, body condition and reproductive ...

Effect of soluble nitrogen level in the ration on protein utilization by high producing dairy cows (Texas A&M University. Libraries, 1977)Twenty Holstein cows, six to 20 weeks in lactation were randomly allotted to four treatments in a complete block design to determine the effect of nitrogen solubility on protein utilization by dairy cows fed rations differing ...

(Texas A&M University. Libraries, 1988)A factorial experiment with four levels of crude protein [CP; 133 (HP), 100 (MP), 67% (LP) of NRC requirements and a control group which received no supplemental feed], three times of supplement initiation [TIME; mid- (P1) ...
-
(Texas A&M University. Libraries, 1984)Many peptides that are known to exist in the gastrointestinal tract and have established physiological functions in the process of digestion have also been localized in the brain. Several of these peptides are known to ...
-
(Texas A&M University. Libraries, 1980)Four experiments were conducted with Indian River broiler chicks in which the protein and energy levels were fed in different combinations in an attempt to produce a broiler at 49 days of age with reduced body fat while ...
-
(Texas A&M University. Libraries, 1985)Two experiments were conducted with commercial egg-type laying hens to determine the effects of housing body weight and parental egg weight on egg quality and laying hen performance. In experiment 1, egg production improved ...
-
(Texas A&M University. Libraries, 1992)Trial I. Twelve mature Thoroughbred horses were used to evaluate the efficacy of a fat-supplemented diet to maintain muscle glycogen stores and reduce thermal stress in exercising horses. In this study, exercising Thoroughbred ...
-
(Texas A&M University. Libraries, 1992)Lipid is a vital macronutrient that provides energy and fatty acids which mediate important biochemical processes. Lack of information on the specific essential fatty acid (EFA) requirements of red drum, as well as their ...
-
(Texas A&M University. Libraries, 1981)The feasibility of polyculturing Macrobrachium rosenbergii and Tilapia aurea was examined in 500 m('2) earthen ponds in central Texas. Monoculture of each species was also undertaken to provide comparative data. Secondary ...
-
(Texas A&M University. Libraries, 1980)Three different studies were conducted during the 1976, 1977, 1978 growing seasons with cool season annuals to characterize the composition of available and consumed forage under different grazing pressures and to interrelate ...
-
(Texas A&M University. Libraries, 1987)An experiment was conducted to measure voluntary intake, nitrogen flow and digestibility of fiber and nitrogen fractions in the gastric (G), small intestines (I) and hindgut (H) digestive segments of crossbred yearling ...
-
(Texas A&M University. Libraries, 1985)Freshwater shrimp, Macrobrachium rosenbergii, were fed experimental diets containing no fat, purified fatty acids (linoleate, linolenate, palmitate) and lipids of plant and animal origin. Gas chromatographic analysis of ...
-
(Texas A&M University. Libraries, 1987)The results of three different experiments involving different aspects of digesta flow in ruminants are presented in five chapters. In experiment one, increasing level of either rice hulls or ground hay from 0 to 30% in a ...
-
(Texas A&M University. Libraries, 1983)The first of two experiments was initiated in August 1975 to investigate methods to improve the management of goats on rangelands. Experiment I compared the botanical and nutritive composition of diets collected from ...
-
(Texas A&M University. Libraries, 1980)A study was intiated in May 1977 to examine the interaction of brush management and season on herbaceous production and composition,, chemical and botanical composition of cattle diets, and performance of lightweight steers ...
-
(Texas A&M University. Libraries, 1979)Clinical responses, general immune responsiveness, and lymphoreticular morphology were studied in 3 groups of yearling Hereford steers fed at low energy levels, maintenance energy levels, and high energy levels for 141-144 ...
-
(Texas A&M University. Libraries, 1984)A series of cattle in vivo and in vitro experiments were conducted to investigate ruminal fermentation, digestibility, growth patterns, energy retention and rate of passage responses to physical and chemical processing of ...
-
(Texas A&M University. Libraries, 1986)Two experiments were performed in order to determine the methionine and choline requirements for maximum protein synthesis by primary cultures of chick hepatocytes. In experiment 1, a 4 x 8 factorial design was employed ...
