(Texas A&M University. Libraries, 1984)A trial was conducted on pastures of Brazos bermudagrass in 1981 and 1982 to study both animal and pasture responses to grazing. Each pasture was divided into four paddocks to permit rotational grazing. Measurements were ...
-
(Texas A&M University. Libraries, 1986)Habitat factors, feeding ecology, and physiological body condition of northern shovelers (Anas clypeata) were studied on saline wetlands of the Texas Gulf Coast, and on several freshwater lakes 18 km inland. The hypothesis ...
-
(Texas A&M University. Libraries, 1990)The objective of this study was to calibrate and validate the Texas A&M forage dynamics, diet selection, and sheep production models for the Edwards Plateau region of Texas. Field data from three sites, one near Brady and ...
-
(Texas A&M University. Libraries, 1985)Five paddocks of a heavily stocked (3.3 AUM/ha) rotational grazing (RG) system at two stocking densities, two paddocks simulated 14 (RG-14) and three paddocks simulated 42 (RG-42) paddocks per herd, and a moderately stocked ...
-
(Texas A&M University. Libraries, 1981)To determine if amino acids are released equally during ruminal protein degradation, 4 hr ruminal in vitro degradation was determined on 10 proteins. Correcting for recovery of each amino acid, net release of 12 amino acids ...
-
(Texas A&M University. Libraries, 1977)Differences in adipose and skeletal muscle tissues between double-muscled (DM) cattle and normal cattle fed high energy or low energy rations were analyzed; 4 DM and 2 normal cattle were fed a high energy ration, while 3 ...

Characterization of puberty and growth near puberty in five cattle breeds and their diallel crosses (Texas A&M University. Libraries, 1977)Pubertal measurements and monthly weight and height measurements of 424 bulls and 475 heifers involved in a diallel mating of Angus, Brahman, Hereford, Holstein and Jersey cattle were analyzed to characterize puberty and ...
-
(Texas A&M University. Libraries, 1985)Thirty two feedstuffs and lysozyme were hydrolyzed using either Ba(OH)2, NaOH or LiOH and analyzed by ion-exchange chromotography to determine which gave the most accurate and repeatable results. The tryptophan recovery ...
-
(Texas A&M University. Libraries, 1976)Two factorial designed individual pig feeding trials and a digestion trial were conducted to delineate the effect of lysine, crude fiber and free gossypol in cottonseed meal (CSM) on the performance of growing pigs fed ...
-
(Texas A&M University. Libraries, 1979)The relationship of voluntary intake of grazed forage with digestibility, gastro-intestinal fill, turnover of undigested residues and rates of degradation and passage of forage particles was studied in 1977 and 1978 by ...
-
(Texas A&M University. Libraries, 1986)Various studies for the development of a purified diet for penaeid shrimp were investigated. No difference in food-seeking behavior and diet consumption was observed in shrimp fed diets with attractant mixtures of 6% and ...
-
(Texas A&M University. Libraries, 1983)Reciprocal influences of plants and animals were investigated in a study conducted in 1979 and 1980 by varying the ratio of cattle, sheep, and goats in five pasture grazing populations. Diet selection, voluntary forage ...
-
(Texas A&M University. Libraries, 1990)The dietary requirements for calcium, phosphorus, Ca:P ration, copper, iron, zinc and selenium as well as the effects of phytate on zinc bioavailability to juvenile P. vannamei were evaluated utilizing a casein/gelatin ...
-
(Texas A&M University. Libraries, 1976)Three experiments were conducted, with White Leghorn laying hens, to compare a conventional molt procedure with the use of zinc as an effective resting agent. In experiment one a molting and resting method were compared. ...
-
(Texas A&M University. Libraries, 1980)Barley (TAMBAR 401), wheat (TAM 101), oats (Coker 234), and wheat middlings were fed to 40 kg cannulated pigs to determine amino acid (AA) digestibilities at the end of the small intestine and over the total tract. Percentages ...
-
(Texas A&M University. Libraries, 1988)Thirteen standard metabolism trials were conducted from May 1986 to June 1987 with white-tail deer (Odocoileus virginianus) utilizing a pelleted diet or one of 3 browse species (guajillo, Acacia berlandieri; blackbrush ...
-
(Texas A&M University. Libraries, 1978)Economy of egg production is greatly affected by the quality of the egg shell and its ability ot withstand shock and resist breakage. The egg industry loses no less than 250 million dollars annually because of egg breakage ...
-
(Texas A&M University. Libraries, 1978)Experiments were conducted with 380 Hy-line pullets fed dietary supplements of 0, 5, 10, or 15 percent sand for twelve 28-day periods and with 440, 120, and 540 day-old Hubbard x Hubbard broiler chicks fed diets with up ...
-
(Texas A&M University. Libraries, 1987)Fifteen crosses of day-old Shaver Single Comb White Leghorn egg-type chicks were used to study the effect of early protein restriction on growth and subsequent performance during lay. Four dietary protein regimes ...
-
(Texas A&M University. Libraries, 1986)A study was conducted to determine the effects of increasing dietary pre-lay calcium levels from 1.00 to 2.00 or 3.00% between 15, 17 or 19 weeks of age. A total of 840 Single Comb White Leghorn pullets were randomly ...
