Abstract. Title of the paper: Level estimation of metabolic parameters in the glucose tolerance test (GTT) of young bulls The metabolic parameters of the glucose tolerance test are suitable for an additional recommendation for the valuation of the breeding bulls before the start of the offspring’s test could be given. Very important is the level of glucose half live to the begin of lactation of the cows. The other limit is the hyperglycemias greater than 10 mmol/l (or 180 mg/dl) in the glucose level in the blood. The glucose half live measured nearly 48 minutes is comparable in the 8th week post partum in lactation of cows with the young bulls in the age one year. Their combination with the pedigree breeding value is leading to increase of information, that could be utilised to the selection of improper bulls if the present results were confirmed.

Abstract. Titel of the paper: Investigations into glucose tolerance test in cattle. I. Relations to stage of lactation and milk yield. Intravenous glucose tolerance test was used in 104 randomly selected milk cows to proove the influence of stage of lactation on test results. The test period enclosed the time from 8 weeks ante partum ( begin of dry period) to 36 weeks post partum. In another trial the glucose tolerance test was applied in 68 first lactation cows in the time from 2 to 7 days post partum. The test results were correlated to parameters of milk yield of the following lactation. The probands belong to two breeds (Friesian Dairy Cattle, SMR and Holstein-Friesian HF) The Parameters of glucose tolerance test show significant changes in the time from the dry period to the lactation cycle, which can be seen as a mean for supporting milk production. The glucose and insulin related parameters differ in their reaction in dependence on time of lactation. Back fat thickness as an parameter for body fat content shows a similar behaviour as insulin related parameters. In this context their were prooved significant correlation coefficients between parameters of milk yield and insulin function in the range from 0 3 to 0 6 But there were seen no relevant relations between glucose related parameters and milk yield datas. No substantial differences were established between the Friesian Dairy Cattle and Holstein-Friesian cows.

Abstract. Title of the paper: Relationships between parameters of the glucose tolerance test by young sires and estimated their breeding values A high milk Performance connected to a sound health regarding metabolism and a sufficient fertility in dairy cows depends on a well balanced distribution of energy in body. The terms "type of tumover" and "type of deposition" embody two extremes of food energy preferably for milk production or for body composition. Insulin plays an outstanding role based on its central position in energetic metabolism. The function of insulin may be recorded by means of the intravenous glucose tolerance test (GTT). The reaction of insulin and glucose was investigated after infusion of 1 g Glucose/kg075 because of the probable genetic determination of the reactive ability. The coefficients of heritability range from h2 = 0.16 + 0.10 to h2 = 0.28 ± 0.16. Investigating 28 sires the correlation coefficients amount to r = 0.5 for parameters of gluccose tolerance test and estimated breeding values which is closer than those between pedigree breeding value and glucose tolerance test.This is expecting additional Information for young sires before the insert of the test.

The association between several gene polymorphisms, the estimated breeding values for milk performance traits, and glucose metabolism measured by the glucose tolerance test (GTT) in German Holstein sires were evaluated. Polymorphisms in DGAT1, GH1, GHR, FASN, and OLR1 genes were not associated with the GTT. A significant relationship was obtained for the DGAT1 AA/GC polymorphism and estimated breeding values for milk performance (milk yield, fat and protein yield, fat and protein percentage). The polymorphism in GHR was significantly associated with estimated breeding values for fat yield, and the polymorphism in OLR1 with estimated breeding value for protein yield. It shows the importance of the polymorphisms and makes their use in the breeding possible. GTT may be helpful in metabolic analyses, but the gene polymorphisms assessed in our study were not associated with GTT traits and further studies should examine other gene polymorphisms to support the role of GTT for potential breeding purposes.

This show the Variation, the genetic determination and the mean correlations between physiological indicator and estimated breeding value by 0.40 to 0.50. The offspring's breeding value is suitable equivalent examined physiological indicators. These relationships are affected by factors such as experimental conditions, age and nutritional State of animals.

Background: Inadequate Blood Transfusion is responsible for various problemsin children with Thalasseima. On the other hand, repeated transfusions are related with hazards.About 25-50% of the children with thalassemia major have impaired glucose tolerance (IGT)or diabetes. Objectives: To find out the frequency of IGT in children with blood transfusiondependent β thalassemia. Study Design: Descriptive analytical study. Setting: Department ofPediatrics, Shahida Islam Teaching Hospital, Lodhran. Period: 1st July 2017 to 31st December2017. Material and Methods: Known 120 cases of beta Thalassemia major children between3-17 years of age that were regularly transfused. Demographics, disease history and personalinformation regarding all the patients were collected. Glucose tolerance test was performedand Serum ferritin levels were measured. Results were analyzed by SPSS software version20.0. Results: There were 78 (65.0%) children between 3-10 years and 42 (35.0%) between11-17 years. There were 70(58.3) male and 50 (41.7%) female. Frequency of impaired glucosetolerance was noted in 15 (12.5%). Conclusion: Frequency of IGT is high amongst children withthalassemia major having regular blood transfusions.
