In the various experiments outlined above, attempts have been made to elucidate some of the important factors influencing the normal bile excretion in Merino sheep. This work was undertaken primarily with the view of ...

1. The toxic principle of the Vermeerbos, Geigeria aspera, has been isolated. It is a dibasic acid C₁₈H₂₈O₇ and has been named “Vermeeric acid”. On standing in the air, Vermeeric acid gradually loses two molecules of water ...

1. The relationship between C.R. length and weight of two series of foetuses from Grootfontein School of Agriculture, Cape Province, and Ermelo, Transvaal, is considered. 2. The thirteen foetuses used in Sex Physiology ...

Since the Questionnaire dealt essentially with African cattle and only incidentally with cattle in certain countries outside Africa, it seems advisable to conclude by referring firstly to the position within Africa and ...

Of several living bovine cases of congenital porphyrinuria, discovered on a farm in Swaziland and all the progeny of a single pure-bred shorthorn bull (see Fourie, 1936), one animal was slaughtered for experimental ...

When the daily ration of Merino ewes contained 0.05 gm. KI for a period of about twelve months no effects were observed in bodyweight and food consumption. Reproduction was, however, abnormal in all the groups receiving ...

1. Doses of 3, 4, 5, 6, 10 and 15 c.c. of pure Tetrachlorethylene per sheep are not efficient for the removal of the hookworm – G. pachyscelis. 2. Doses of 3, 4, 5 and 6 c.c. pure Carbon tetrachloride are not ...

(1) Although toxins for the experimental reproduction of the disease have not actually been obtained from the nodular worms, there is very strong circumstantial evidence that during the course of the disease poisonous ...

The increase in surface area of the Merino foetus is discussed. The relationship between surface area and body weight, as estimated from the present series of foetuses is expressed by the equation a=3.320w⁰‧⁷⁷⁸. Several ...

1. Data are presented on the oxidation and reduction of elementary sulphur by animal tissues in vitro, and the enhancing or otherwise effects of certain chemicals on these reactions are also shown. 2. All protein tissues ...
