EXPERIMENTAL PROCEDURE

Ten pens of males and ten pens of females (Lancaster X New Hampshire) were used in the first experiment. Twenty pens of Single Comb White Leghorn males were used in the second experiment. In either experiment each pen contained twenty, day-old birds. Five experimental treatments were used resulting in four replicates being used with each treatment. Eight pens of birds were fed vitamin K low basal diet as shown in Table 1. Four of these pens served as the positive control and were not inoculated with E. tenella. The diets of the other three experimental groups were formed by the 1

addition of one gram of MSB per ton of feed, twenty grams of MSB per ton of feed, and three percent of alfalfa leaf meal respectively to the basal diet. These three experimental groups and four pens of the basal fed birds were inoculated with sporulated oocyts of E. tenella. Each bird in the first experiment was inoculated with 50,000 oocysts at 23 days of age while each of those in the second experiment received 60,000 oocysts at 28 days of age. All chicks were reared in electrically heated battery brooders with raised screen-wire floors. Feed and water were given ad libitum. Water troughs were washed and fresh water supplied daily in an effort to limit the synthesis of vitamin K in the watering troughs. The individual body weight of all chicks was obtained at time of inoculation and again fourteen days post inoculation. Mortality records were kept throughout the experiments. However, only mortality reTABLE 1.—Composition of basal diet Ingredient Yellow Corn Soybean Oil Meal (50% protein) Defluorinated Phosphate 1 Ground Limestone Salt Vitamin Mix2 1

ARMS and Tugwell (1956) reported that mortality from cecal coccidiosis in chicks could be significantly increased by the addition of dicumarol to the diet. This increased mortality was attributed to prolonging blood clotting time, since the addition of one gram per ton of menadione sodium bisulfite2 (hereafter referred to as MSB) significantly reduced mortality when added to the diet containing dicumarol. In view of these findings experiments were designed to study the possibility of reducing mortality from cecal coccidiosis by the addition of MSB to a vitamin K low diet.

peared to furnish adequate vitamin K to prevent excessive mortality from coccidiosis. Recently Otto et al. (1957) have also shown that vitamin K is necessary to prevent excessive mortality from coccidiosis. The addition of a source of vitamin K to the basal diet, in the second experiment, resulted in significantly reducing ing blood clotting time (Table 2). This reduction in blood clotting time may have been expected since vitamin K has been shown to be necessary for normal blood clotting (Dam, 1935).

In the second experiment, thirty birds were selected at random from each treatment group for blood clotting time determinations. Clotting times were measured by the capillary tube method with blood obtained by puncturing the wing vein. Statements of probability in this paper are based on analysis of variance according to Snedecor (1956) with significant treatment differences determined by Duncan's multiple range test (1955).

teridge et al. (1944) increased the environmental temperature of laying pullets by the use of artificial heat and insulation over a range of 37.8°F. to 59.9°F. and got no effect upon egg production. Hutt (1938) reported breed differences in susceptibility to extreme heat. White Leghorns withstood drastic increases in environmental temperatures better than did Rhode Island Reds or Barred Plymouth Rocks. Other workers have made similar observations. Fox (1951) demonstrated that White Leghorn hens withstood high temperatures better than Rhode Island Red hens.

UMEROUS studies at various geographic locations over a period of several years indicate rather conclusively that high environmental temperature is one of the major factors influencing the decline in egg production during the summer months. Winchester (1940), Byerly et al. (1947), Wilson (1948), Ragab and Assem (1953) and others have shown that reproductive performance of domestic fowl is adversely affected by high environmental temperatures. Bruckner (1936) found that in a poultry house artificially heated to a mean temperature of 60°F., the health, body weight, and egg size of the birds were adversely affected. Gut-
