(Texas A&M University. Libraries, 1985)To further study the endocrine environment of foaling mares at different levels of body condition, 12 mares were divided into two groups, one designed to foal at a condition score of 4.5 or less and the other to maintain ...
-
(2019-03-25)Information on mussel reproductive life history, age and growth is important for understanding evolutionary and ecological relationships and predicting how species will respond to threats and various conservation and ...

(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )Everyone wants good cows! These are females that wean a calf annually throughout their lifetime. A cow’s ability to do this depends heavily on her performance as a heifer. Thus, good heifers, make for good cows. There ...

(Texas A&M University. Libraries, 1978)To determine if luteinizing hormone (LH) patterns were different between ovariectomized Brahman and Hereford cows, before and after 500 ug of GnRH, animals were bled at 15-min intervals for periods of 4 and 6 hr. Serum was ...
-
(Texas A&M University. Libraries, 1989)The molt cycle was characterized in the white shrimp Penaeus vannamei based upon changes in the morphology of pleopod setae. These characters were used subsequently to determine changes in ecdysteroids and related biosynthetic ...
-
(Texas A&M University, 2005-11-01)Endometrial glands are required for adult uterine function and develop post-natally in mammalian species. Therefore, studies were conducted using neonatal ewes as a model to determine: 1) the roles of estradiol-17-alpha ...

(Texas A&M University. Libraries, 1992)Sequences at the 5' termini of the genomic RNAs of brome mosaic virus (BMV) and other (+)-stranded RNA viruses have been shown to resemble the internal control regions (ICRs 1 and 2, or A and B boxes) of tRNA genes. In ...
-
(Texas A&M University. Libraries, 1985)The spermatids of the bryophytes are the most structurally complex cell produced by the embryophytes. They consist primarily of the blepharoplast (multilayered structure, spline and basal bodies), nucleus, two mitochondria, ...
-
(Texas A&M University. Libraries, 1985)Serum steroid hormone profiles were investigated in mares foaling at different levels of body condition. Six mares (Thin) were managed to lose weight during late gestation and foal in thin condition (condition score [less ...
