RESUMO
This work was carried out from a large herd of Zebu Cattle (Indu-Brasil breed) situated in Araçatuba, SP, where the cattle has been raised in range conditions. As a managerial practices the heifers are put together with the sires, in a freely consorting plan, when they are 2 to 2,5 years-old. With an idea to gather some added information about this subject, it was considered to be worthwhile to observe if heifers which were permitted to run with the male, in the herd, younger than 2 to 2,5 years old, could calve their first youngs at an earlier age than those which were older when mated for the first time. The heifers were selected from the herd at random and were consorted with the sires (ratio = 1:25), at different ages, in two groups as follows: Group I) Eighty-two heifers with the age of 12 to 18 months, and Group II) Eighty-five heifers with the age of 20 to 36 months. The null hypothesis, therefore, was that females of the first group should bore their first young at the same mean age of those heifers pertaining to the second group. The alternative hypothesis would be that the females of the first group should produce their first youngs earlier than those heifers of the group II. The results were as follows: (the level of significance was 0,05) Group I: X = 1.262,30 days; S = 167,70 days and V = 13,29% Group II: X = 1.205,93 days; S = 141,33 days and V = 11,72% It is cl

RESUMO
In the experimental epidemiological study on the use of phenothiazine in the profilaxis of chicken ascariasis the author was able to conclude that: 1 The number of worms found in the intestines of susceptiblc chicken that lived on soil previously inhabited by fowls infected with A. galli and treated continuosly with phenothiazine by oral route, is significantly lower than that observed in the intestines of susceptible chicken that lived on soil previously inhabited by fowls infected and not treated. 2 The number of worms found in the intestines of susceptible chicken that lived on soil previously treated with phenothiazine and inhabited by birds infected with A . galli, is significantly lower than that observed in the intestines of susceptible chicken that stood on soil not treated with the drug and inhabited by infected animals. 3 The number of worms found in the intestines of chicken that stood on soil inhabited by birds infected with A. galli and treated continuously with phenothiazine, by oral route, is significantly lower than that observed in the intestines of susceptible chicken that stood on soil treated with the drug and inhabited by infected animals. 4 The number of worms found in the intestines of susceptible chicken that stood on soil that had been inhabited by birds infected by A. galli and treated continuously with phenothiazine, by oral route administered

RESUMO
Studying the in vitro effect of phenothiazine upon the embryonic development of A. galli at various phases of their evolution the author was able to conclude: a) The eggs were highly susceptible to an inhibitory action of the drug, provided the treatment started inside the first three days of development, at 28 C; after the third day the susceptibility decreased rapidly, seeming to disappear after the seventh day of evolution at the above temperature; b) When the treatment was instituted on the first day, a 24 hour period of contact of the eggs with the drug was enough to determine an irreversible inhibition of embryonic development in all of them .

RESUMO
The total cholesterol was determined in 20 throughbred horses, with an average of 101.9 ± 7.06 mg/100 ml of serum. When compared with other published data, the results are considered low. As a matter of conjecture and in order to justify the values disclosed, some tentative explanations are offered concerning mainly the breed as well as the high level of indirect bilirubin present in the serum of horses, during the training period at the Jockey Club of São Paulo, Brazil.

RESUMO
Normal thoroughbred horses in the process of training at the São Paulo Jockey Club. When submitted both to direct and indirect bilirubin serum tests yelded values that were respectively 0,71 ± 0,30 and 2,33 ± 0,72 mg/100 ml. The indirect bilirubin level from animals with nuttaliosis was rather increased; there was however a considerable variation due probably to the phase of the disease. In chronic cases hyperbilirrubinaemia was not detected. As an objetive criterium for judging if horses which have recently been under treatment for nuttaliosis might be returned to training activities, the AA. suggest serum bilirubin determinations.

RESUMO
The average incubation period for Babesia bigemina was 7,2 ± 0,2 days in female hosts and 8,4 ± 0,3 days in males. As for the Anaplasma marginale the average was 28,2 ± 0,318 for female hosts and 28,7 ± 0,515 for males. The sex difference in average incubation period was statistically significant only for Babesia bigemina. As for the treatment of babesiosis there was no apparent advantage in the administration of acriflavin. For the treatment of anaplasmosis, terramicin by intravenous route showed good results, while antimalarics (Paludrine and Aralen) seemed to be of sligt or no value, when administered by oral route. Some modifications of the premunition technique are suggested.

RESUMO
The observation of cattle serum bilirubin levels during babesiosis and anaplasmosis indicates that this verification is not clinically interesting since the bilirubin increase occurred only in 4 of the 10 observed cases and this only when anemia had already developed very far. The determination of hemoglobin, hematocrit value and or red blood cells count are rather safer and more precocious indications than the bilirubin estimation. The creatine rate diminished in the course of the illness.

RESUMO
The ascorbic acid content in potatoes purchased on the local market, was determined for the different months of the year. By comparing our data with the ones from other authors, it was found that, for young potatoes the vitamin C levels obtained by us were among the highest. Furthermore, the loss resulting from storage is less intense here. As our climate allows at least two annual harvests, potatoes should be considered in this part of the country (São Paulo, Brazil), as a better source of vitamin C than in those countries subjet to a hard winter.

RESUMO
Polivinylborate, a compound mixture of polivinyl alcohol with boric acid, reacts with iodine in the same way as the amilo-solution, giving raise to blue color. The author carried out this reaction in the detection of boric ion in milk, butter and sausage. The simplicity of the test and its sensibility provided an easy way for the detection of the boric acid used as preservative in the above mentioned products.

RESUMO
The hemoglobin, total plasm protein and hemotocrit contents of 20 animals of the Red Danish breed, were determined during the premonition against cattle plasmosis. It was emphazised a pronounced fall in the hemoglobin and hematocrit levels, namely during the phase of anaplasmosis attack. On the other hand the total protides level showed no remarkable variation in the course of the disease. The authors suggest that the presence of cattle plasmosis in this country is the most important factor which would explain in part, either the low adaptability or the low hemoglobin content and the reduced number of hematias in imported cattle.

RESUMO
After rectal introduction of hydrogen peroxide in treating canine helmintosis, it can be shown that the fluid went ano-oralwards, through the entire digestive tract, by adding starch to the H202 solution and performing the iodine reaction on the vomited material. The vomit can therefore, be taken as a sign that the antihelmintic has, as desired, gone through the whole length of the digestive tract.
