A Study Of The Prevalence Of Gastrointestinal Nematodes In Goats Obtained From Northwest Arkansas, Christine Rose Weingartz
A Study Of The Prevalence Of Gastrointestinal Nematodes In Goats Obtained From Northwest Arkansas, Christine Rose Weingartz
Graduate Theses and Dissertations
Parasitic helminths have always been an issue in small ruminant production; pathogens that pose great negative impact on goat health and productivity. Insufficient work has been done to document the prevalence of parasitic helminths in the United States, especially in the south and southeast, where the largest goat populations are found.
The aim of this study was to survey the prevalence of infections by gastrointestinal nematodes in goats in Northwestern Arkansas. Gastrointestinal tracts were examined from 41 goats of various locations around Northwest Arkansas. Worm species were identified and population burdens were determined. Coprology was correlated with the actual worm …
Improvement In Simple Artificial Insemination In Sheep Using Chilled Extended Semen And Consideration Of Fertility In Ewes, Mohan Acharya
Improvement In Simple Artificial Insemination In Sheep Using Chilled Extended Semen And Consideration Of Fertility In Ewes, Mohan Acharya
Graduate Theses and Dissertations
Three studies were conducted to improve simple artificial insemination in sheep using chilled extended semen and evaluate methods to predict fertility in ewes. The first study evaluated the effect of semen extenders and storage temperature on motility parameters of ram semen stored for up to 72 h. Single semen collected from each ram was divided into four parts and extended using four extenders: milk, TRIS, TEST, and CJ-2, diluted to 600 million sperm/ml and loaded into 0.25 ml straws for storage at 4 and 15° C. Most of the CASA motility parameters were higher after extension and storage at 4 …
Supplemental Trace Minerals (Zn, Cu, And Mn) As Sulfates Or Hydroxy Trace Mineral Sources For Beef Heifers, Randy Hunter Burnett
Supplemental Trace Minerals (Zn, Cu, And Mn) As Sulfates Or Hydroxy Trace Mineral Sources For Beef Heifers, Randy Hunter Burnett
Graduate Theses and Dissertations
Crossbred heifers (n = 286, 255 ± 4.5 kg initial BW, 295 ± 16.5 d of age) were used over a 2-yr period to determine the effects of mineral source on beef heifer development at 2 locations (n = 71 and n = 72, Fayetteville, blocks 1 and 4; n = 72 in each of 2 breeding groups, Batesville, blocks 2 and 3). Heifers were stratified based on initial BW, age, health, prior research projects, and sire, and then assigned to 6 groups of 12 heifers, that were assigned randomly to 1 of 2 trace mineral treatments. The 2 treatments …
