Partial characterization of gelatinases produced by preimplantation porcine, ovine and bovine embryos

Chamberlin, RaeAnne (1995-08-08)
Perennial ryegrass nonstructural carbohydrates in dairy cattle nutrition

Buyserie, A. C. (Annette C.) (2004-09-21)
Phospholipase A₂ mRNA expression in testes from roosters (Gallus domesticus) characterized by high or low sperm mobility phenotype

Eguchi, Yuko. (2000-09-22)

Previous research has shown that sperm mobility is a primary determinant of fertility in fowl. Sperm mobility denotes the net movement of a sperm population, and males can be characterized by phenotype. Sperm acylcarniti ...
Physiological factors affecting ovine uterine estrogen and progesterone receptor concentrations

Prater, Patrice L. (1990-11-14)

Two experiments were conducted to determine whether in ewes uterine concentrations of estrogen and progesterone receptors are affected by the presence of a conceptus or by the hormonal milieu associated with extremes ...
Plasma and fecal progestins during placentation in the mare

Von Deneen, Karen M. (2002-07-10)
Porcine zona pellucida immunocontraceptive vaccine for horses

Bartell, Jennifer Ann (2011-12-05)

The Bureau of Land Management (BLM) maintains a growing number of feral horses on public rangelands. With population growth rates as high as 22% annually, herds are exceeding their carrying capacity and millions of dolla ...
Positive and negative regulators of adipocyte differentiation in primary culture

Suryawan, Agus (1995-08-17)
Postpartum disorders associated with high potassium forages in Holstein cows

Crill, Roberta L. (1998-07-10)

Until recently, occurrence of milk fever (MF) has been attributed to prepartum calcium intake. However, researchers in Iowa have concluded that high prepartum dietary potassium (K) is the major cause of MF. Potassium c ...
Preliminary investigation of artificial incubation of emu eggs, and alternative feeds and management techniques for emu chicks up to ten weeks of age

Allen, Carol Ann (1999-10-01)

A preliminary study was conducted to establish baseline data for emu artificial egg incubation and emu chick growth and management. Three experiments examined factors affecting hatchability of emu eggs that occur prior t ...
Progestin profiles near parturition in light horse, pony and miniature horse mares

Baumholtz, Heather Mackie (1998-08-06)
Puberty development and reproductive performance in beef heifers fed rations supplemented with Oregon by-product feeds

Oswald, Keely E. (2011-05-09)

In the majority of management scenarios, it is imperative that beef replacement heifers calve at two years of age. In order to achieve this goal, yearling heifers should reach 60 to 65% of their mature body weight by 13 ...
Purification and characterization of recombinant calpain-5

Wang, Mei-Chuan (2003-10-29)

Recombinant human calpain-5 was expressed in insect cells using a baculovirus system. The expressed calpain-5 was purified by both traditional chromatography and by affinity-column chromatography. Both methods yielded ...
Regulation of 3T3-L1 preadipocyte differentiation in culture

Chen, Chu-liang, 1961- (1996-06-11)
Regulation of adipose stromal-vascular cell differentiation in culture

Akanbi, Kamil Agbolade (1992-03-16)

Primary cultures of stromal-vascular (S-V) cells from adipose tissue were used to investigate the regulation of preadipocyte development. Differentiation of S-V cells was found to be under hormonal control. Insulin and ...
Regulation of skeletal muscle protein degradation by u-calpain and development of a skeletal muscle-specific inducible expression system

Xiao, Ying-Yi (2001-03-15)

The first goal of this study was to understand the role of u-calpain in skeletal muscle protein degradation in cultured muscle cells. Several strategies were developed to down-regulate endogenous u-calpain activity and ...
The relationship of estradiol to embryo-maternal interactions in the llama

Powell, Susan A. (1999-08-16)

In the first experiment, estradiol production was measured in cultured embryos collected on Days 7, 9, 11, 13 and 15 post-mating. Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P< ...
The relationship of prepartum body condition score to postpartum colostrum quality and milk yield and composition in polypay sheep

Al-Sabbagh, Tariq Ashour (1994-06-21)
Relationships among rump and rear leg type traits and reproductive performance in Holsteins

Shapiro, Leland Sanford (1990-12-20)

This study was conducted to determine the relationships among the linear type traits of rump angle, rump width, rump length, rear legs side view, rear legs position, rear legs rear view, tailhead, vulva angle, mobilit ...
The role of calpains in muscle protein degradation

Ou, Bor-rung (1994-08-29)
Role of IL-8 and TIMP-2 on term canine trophoblast migration, invasion, and proliferation

Gullaba, Justine Marie (2013-05-06)

Placental pathologies are not uncommon in dogs. For example, in primiparous bitches, the reported incidence of subinvolution of placental sites is 21% - 100%. Despite years of research in multiple species, the mechanisms ...
