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 ...

(Texas A&M University. Libraries, 1981)A study was designed to evaluate the pulsatile patterns of plasma LH in five mature Jersey cows on day 3 of two consecutive estrous cycles, and at different time intervals following ovariectomy (4, 42 and >59 days ...
-
(Texas A&M University. Libraries, 1961)One thousand C -57 black mice were exposed to chronic continuous radiation from a Co⁶⁰ source. The dose rates employed were 0, 2, 5, 10 and 20r per day (23 hours), for total accumulated doses of 0, 60, 120, 240, 480 and ...
-
(Texas A&M University. Libraries, 1964)A study was conducted to obtain data on effects of chronic radiation at levels of 1, 2, 5, 10, 20, and 40r per day for a total dose of 30, 60, 150, 300, 600, and 1200r respectively on Holtzman strain offspring irradiated ...

(Texas A&M University. Libraries, 1983)In the first experiment twenty-four postpartum mares were infused on days two and three with either: (1) .2mg of estradiol benzoate (E(beta)) in a carrier 6 of 60 ml of physiologic saline, (2) 1 x 10('6) units of K Pencillin ...

(Texas A&M University. Libraries, 1976)A trial was performed attempting to shorten the postpartum interval of nursing cows by administration of exogenous progesterone (P) (4-pregnene-3, 20-dione) alone or combined with estradiol valerate (1,3,5, [10]-estratriene-3, ...
-
(Texas A&M University. Libraries, 1982)One hundred and six primiparous Brahman percentage cows were used to determine the effect of suckling manipulation on postpartum reproductive performance. Variables measured included weight, body condition scores, pelvic ...

(Texas A&M University. Libraries, 1982)The objective of this research project was to investigate the effects of nutrition and stress related factors on basic physiological parameters. Studies were designed and conducted independently to evaluate (1) the effects ...
-
(Texas A&M University. Libraries, 1984)A study was conducted to establish a 24 h serum melatonin profile in neonatal lambs and to correlate this profile with the maternal 24 h profile. Twin female crossbred lambs were separated, at birth, into 2 groups (suckled ...
-
(Texas A&M University. Libraries, 1976)Peripheral plasma levels of 17-hydroxyprogesterone (17-OHP), progesterone (P) and luteinizing hormone (LH) were determined by radioimmunoassay procedures in cyclic pluriparous cows from 36 hr before estrus until time of ...
-
(Texas A&M University. Libraries, 1981)A group of three experiments were conducted in the Central Llanos of Venezuela to determine physiological reproductive effects of ovaries transplanted to the uterine muscle or parotid muscle, the effect of feeding monensin ...
-
(Texas A&M University. Libraries, 1964)A study of the development of wool follicles during the pre-natal stage of the sheep was conducted on a group of Rambouillet fetuses. Factors studied were time of initiation and sequence of follicle development, density ...
-
(Texas A&M University. Libraries, 1981)A study was undertaken to further the understanding of the mechanism by which suckling inhibits the release of pituitary luteinizing hormone (LH) and depresses the postovariectomy rise of plasma LH in lactating mammals. ...
