A Study Evaluating Genetic Trends And Molecular Predisposition To Improved Carcass Quality Of Brahman And Brahman Influenced Cattle, Amanda M. Royer
A Study Evaluating Genetic Trends And Molecular Predisposition To Improved Carcass Quality Of Brahman And Brahman Influenced Cattle, Amanda M. Royer
LSU Master's Theses
The first objective of the current study was to evaluate genetic trends from 10 years of the American Brahman Breeders Association Carcass Evaluation Program from 2004 to 2013. Changes of performance in growth, carcass composition, and carcass quality traits were evaluated. Overall means were calculated to report the total average for each trait along with an average rate of change per year. Growth traits evaluated included feedlot entrance weight (INWT), harvest weight (HRVWT), and average daily gain (ADG). Carcass composition and quality traits evaluated included hot carcass weight (HCW), rib eye area (REA), marbling score (MARB), dressing percent (DP), quality …
The Use Of Assisted Reproductive Technologies To Improve Pregnancy Rates In White-Tailed Deer, Jaclyn C. Lambe-Steinmiller
The Use Of Assisted Reproductive Technologies To Improve Pregnancy Rates In White-Tailed Deer, Jaclyn C. Lambe-Steinmiller
LSU Doctoral Dissertations
Detection of estrus in white-tailed (WT) deer is laborious and often missed, as there are few visual cues presented during the 24 h period in which females are receptive to mating. Reproductive management of WT operations is improved by the use of fixed-timed artificial insemination (FTAI) protocols. Fixed-timed AI removes the need for estrus detection and ensures the breeding of an entire herd, as well as the ability to schedule fawning within predetermined timeframes. Two studies evaluated two FTAI regimens and their ability to synchronize estrous in WT. The first study implemented the administration of eCG 200 IU (im) at …
Three Essays On Land Ownership, Gender, And Agricultural Productivity In The Case Of Developing Countries, Krishna H. Koirala
Three Essays On Land Ownership, Gender, And Agricultural Productivity In The Case Of Developing Countries, Krishna H. Koirala
LSU Doctoral Dissertations
This dissertation set out to evaluate the impact of land ownership and role of gender to the Filipino farmers and to investigate gender difference in agricultural productivity and technical efficiency of Malawian rural households. The first essay investigates the impact of land ownership on the productivity and technical efficiency of rice farmers in the Philippines. We use a 2007-2012 Loop Survey from the International Rice Research Institute (IRRI) and analyzed it by using a stochastic frontier function method. Results show that land ownership has a significant impact on technical efficiency. In particular, counter to the theory, the Comprehensive Agrarian Reform …
Essays On The Effect Of Trade Facilitation On Bilateral Agricultural Trade, Trina Biswas
Essays On The Effect Of Trade Facilitation On Bilateral Agricultural Trade, Trina Biswas
LSU Doctoral Dissertations
This dissertation offers three independent studies that each contributes to the literature on trade facilitation. The papers are built on the gravity model framework where the relationship between trade facilitation variables and the volume of agricultural exports across the border are examined. To deal with the issue of endogeneity, instrumental variable regression is used. The study also corrects for sample-selection bias present in the trade data. The first paper examines the role of e-governance on bilateral agricultural trade. The study finds that better quality of e-governance promotes agricultural exports. Specifically, according to the findings of the paper, the quality of …
Estimating Desirable Cattle Traits Using Latent Class And Mixed Logit Models: A Choice Modeling Application To The U.S. Grass-Fed Beef Industry, Isaac Sitienei
Estimating Desirable Cattle Traits Using Latent Class And Mixed Logit Models: A Choice Modeling Application To The U.S. Grass-Fed Beef Industry, Isaac Sitienei
LSU Doctoral Dissertations
This study examines the preferences for cattle traits using mixed logit and latent class models. Choice experiment data from a 2013 mail survey of 1,052 U.S. grass-fed beef producers were used. The findings indicate that grass-fed beef producers generally preferred lower-priced, heavy animals that were small-to-medium framed and easy to handle for grass-finishing. Black animals that were retained from their own calves were preferred. Relative to intact males, steers and heifers were preferred. Except for the estimated parameter for the weight attribute, the standard deviations for the temperament, body frame, source, color, gender, and price attribute levels were significant at …
