Analysis Of The Reproductive Efficiency Of The Dairy Herd At Western Kentucky University Farm, Gregorio Lagombra
Analysis Of The Reproductive Efficiency Of The Dairy Herd At Western Kentucky University Farm, Gregorio Lagombra
Masters Theses & Specialist Projects
A study of the reproductive performance of 179 dairy cows during the period from December 1978 through March 1984 was conducted at the Western Kentucky University Farm, Bowling Green, Kentucky. The climatic data showed seasonal variation in temperature as follows: winter 3.10C, spring 15.7°C, summer 23.8°C, and fall 12.0°C. The seasonal humidity was similar for winter (81.2%), spring (83.4%), and fall (85.3%); but for summer it was considerably higher (89.4%).
The conception rate varied through all the months but was lowest during the summer months. Seasonal data for conception rate were obtained and the results were as follows: winter 54.1%, …

The Antibody Production By Swine In Response To Sheep Red Blood Cells, Deborah Seymour
The Antibody Production By Swine In Response To Sheep Red Blood Cells, Deborah Seymour
Masters Theses & Specialist Projects
Two experiments were conducted to study the antibody response of pigs challenged with the general antigen sheep red blood cells (SRBC).
In one experiment SRBC's were injected at one of four sties: intramuscularly into the neck, intramuscularly into the ham, subcutaneously into the fore flank or rear flank. These treatments were repeated four weeks later. The antibody responses to the four treatments were determined by microtiter and analyzed statistically. No significant (P> 0. 10) differences were found among responses to the four treatments during the fourth and eighth weeks after injections, but a significant (P<0.05) difference was found during the fifth week among all four groups. Coefficients of correlation showed highly significant (P<.0.01) relationships between SRBC antibody titer during the fourth week after injections and increase in weight of test animals from the beginning of the study until slaughter.
In a second experiment pigs …
The Relationship Between Linear Measurements & Subjective Placings In Elite Angus Cattle, Ted Dyer
The Relationship Between Linear Measurements & Subjective Placings In Elite Angus Cattle, Ted Dyer
Masters Theses & Specialist Projects
The cattle shown from 1981 to 1984 at the American Angus Breeders' Futurity were studied to determine the relationship between linear measurements and the judge's subjective placings. Linear measurements taken prior to the showing included wither height, hip height, and body length for both bulls and heifers. In addition body weight and scrotal circumference were recorded for bulls. A total of 624 cattle were studied-- 407 heifers and 217 bulls.
The cattle were divided into five groups by age and sex to analyze the annual difference in means and standard deviations for all recorded measurements. Among all five groups of …

Effect Of Rations On Some Selected Blood Constituents Of Dairy Heifers, Kamil Akanbi
Effect Of Rations On Some Selected Blood Constituents Of Dairy Heifers, Kamil Akanbi
Masters Theses & Specialist Projects
The study was conducted using nine Holstein heifers with weights ranging from 700 to 990 pounds (lb). The design was a 3 X 3 Latin Square. The three rations consisted of 26.5 lb of corn silage supplemented with 3 ounces of sodium bicarbonate, 26.5 lb of corn silage, and 26.5 lb of soybean and milo haylage per head per day. The rations were offered on a rotational basis for three experimental periods consisting of three weeks each. Blood samples were taken at weekly intervals during each period; plasma concentrations of glucose, ammonia, beta-hydroxybutyrate and volatile fatty acids were determined.
There …
