Gonadotropin releasing hormone-induced alteration of corpus luteum function in beef heifers

Creator:: Rodger, Lynn Dian
Abstract:: Two experiments were conducted to evaluate the effects of gonadotropin releasing hormone (GnRH) on the function of the bovine corpus luteum during the estrous cycle. In Experiment 1, 10 heifers were assigned randomly into two groups with each heifer serving as her own control. Heifers in Group I (n=5) were...

Effect of dietary crude protein level and source of supplemental protein on performance of commercial rabbits

Creator:: Sanchez, William K.
Abstract:: A study was conducted to determine the effect of dietary protein on performance of commercial New Zealand White rabbits. In Part I of this study, three levels of crude protein (17.5, 19 and 20.5%) were fed to lactating does and their offspring during a 12 month period. Total rabbits born...

Inheritance of active and passive immune responses in sheep

Creator:: Berggren-Thomas, Priscilla L.
Abstract:: Six hundred sixteen ewes of six strains were inoculated twice with ovalbumin in Fruends' incomplete adjuvant in order to investigate genetic variation in immune response. Blood samples were collected from the ewes 6 days post-second injection. Serum samples were also collected from their 709 lambs, born in June 1984, between...

Two uses of the synthetic progestagen altrenogest for aiding in the establishment and maintenance of pregnancy in mares

Creator:: Weeks, Linda C.
Abstract:: Studies were conducted in order to evaluate the efficacy of the orally active, synthetic progestagen, altrenogest, for assisting in the establishment and maintenance of pregnancy in mares. In experiment I, nine pony mares were bred, and started on altrenogest treatment on Day 4 after ovulation. On Day 10 after ovulation,...

Dietary factors influencing enteric disorders of rabbits

Creator:: Grobner, Mark A.
Abstract:: An extensive literature review into the causes and controls of diarrhea was followed by three weanling rabbit performance trials to examine the influence of dietary modifications on diarrhea in the rabbit. In the first set of experiments, the ion exchangers clinoptilolite (0, 1.5 and 3.0%) and sodium bentonite (0 and...

Winter supplementation and delayed weaning of an autumn calving beef herd under western Oregon conditions

Creator:: Buehner, Heidi Renata
Abstract:: Two management systems were evaluated in terms of the effects on cow condition score and body weight changes and calf growth rates. The management systems evaluated were winter supplementation of energy, winter creep feeding and delayed weaning. The calves used in this study were born in September and October of...

Supplementation with lasalocid three times weekly to stocker cattle on pasture

Creator:: DelCurto, Timothy
Abstract:: Two experiments were conducted to study the efficacy of feeding lasalocid to cattle on pasture on a three times weekly basis. In experiment 1, 72 crossbred yearling steers were stratified across a randomized block design of 12 pens including three replications of four treatments. Treatments consisted of: (1) .45 kg...

Flow cytometric evaluation of spermatozoan nuclear chromatin structure and viability

Creator:: Ballachey, Brenda Elizabeth
Abstract:: I. Frozen bovine semen samples were measured by flow cytometry (FCM) to determine if FCM analyses could be useful for sperm quality evaluation and prediction of bull fertility. Fluorescent dyes utilized were acridine orange, to measure sperm nuclear chromatin heterogeneity by quantifying susceptibility of the chromatin to denaturation, and rhodamine...
