1298 - Gestation and Sterility in Cows. — Stalfors h., in Monatsciu-fte fur praktische 



Tieiheilkunde, Vol. 27, No. 7-8, pp. 338-35'^. Stuttgart, May 27, 1916. 



I. Studies on gestation. - During the years 1907 to 1915 a large number 

 of in-calf cows were examined for the purpose of determining in which 

 horn of the uterus the foetus was carried. The examinations were made per 

 rectum some time between the sixth and fifteenth week of gestation, that 

 period being the most favourable for the operation ; fluctuation, asj'mmetry 

 and an increase in size of the uterus were taken as symptoms of ])regnancy. 

 With at least half the animals under experiment the ovaries were also ex- 

 amined for corpora lutea though no records were kept of the observations. 



Out of a total of 923 cows examined, 577 cows or 62.5 per cent of the 

 cases carried the foetus in the right horn o^ the womb, and 346 in the left 

 horn, proportions which are approximately those found by other workers. 

 With T05 of the cows, the animals were kept under observation for two 

 successive periods of gestation and in 62 of the cases the foetus was twice 

 carried in the same horn, indicating that the one ovary was rather more 

 productive than the other. The greater productivity of the right ovary 

 with respect to the left is attributed to the pressure exerted by the paunch 

 on the nerves and blood vessels of the left side as well as on the left ovary * 

 itself.
