Abstract:
The objective of this research was to generate baseline information on follicular statistics of Red Chittagong Cattle (RCC).Ten heifers and ten regular breeder RCC cows were selected randomly from BLRI Research Herd. The ovary was grasped by inserting left hand through the rectum and the follicles were visualized by inserting a sectorial probe through the vagina. Ovarian follicles were visualized and recorded by counting on the screen of ultrasonography machine. All visible follicles (>2.0mm) were counted and graded as small (<3.0mm), medium (3.0 to 8.0mm) and large (>8.0mm). The foll

Abstract:
ABSTRACTDairy cows have been identified as common carriers ofCampylobacter jejuni, which causes many of the human gastroenteritis cases reported worldwide. To design on-farm management practices that control the human infection sourced from dairy cows, the first step is to acquire an understanding of the excretion patterns of the cow reservoir. We monitored the same 35 cows from two dairy farms forC. jejuniexcretion fortnightly for up to 12 months. The objective was to examine the concentration ofC. jejuniand assess the genetic relationship of theC. jejunipopulations excreted by individual cow

Our study, which investigates the factors affecting milk yield at metabolic and oxidative stress levels in Holstein breed cows raised in Aksaray Region, is the first at the regional level. It was aimed to perform biochemical and antioxidant screenings according to milk yield levels in healthy Holstein cows raised in the province, and thus, together with the determination of general metabolic parameters, the differences in total antioxidant and total oxidant levels according to milk yield were investigated.

Abstract:
A computer technique for interpreting geophysical logs of drill-holes in quantitative lithologic terms has been developed and tested on the deposits of the late Eocene Coaledo Formation, a well-studied fluvio-deltaic complex in southwestern Oregon. The technique involves the use of induced and natural gamma logs for separation of coal and claystone from coarse-grained detrital rocks and the use of the ratio of resistivity and natural gamma responses (defined here as the "grain size index") to divide the coarse elastic rocks into a series of textural classes corresponding to the Wentworth-Odden

AbstractThis chapter covers various issues related to the experimental design, a statistical technique at the core of a discrete choice experiment. Specifically, it focuses on the dimensionality of a choice experiment and the statistical techniques used to allocate attribute levels to choice tasks. Among others, the pros and cons of orthogonal designs, optimal orthogonal in the differences designs as well as efficient designs are addressed. The last section shows how a simulation exercise can help to test the appropriateness of the experimental design.
