Abstract

The objective of the study was to analyze the potential of fourier transform infrared (FTIR) asstress estimation instrument through measurement of catecholamine (CA) and cortisol (CO) levels byinvasive and non-invasive methods. Twelve heads of Ongole grade (PO) cow from slaughterhouse wereused in this study. Twenty four urine samples of pre-slaughter and slaughtering were collected toevaluate the CA and CO levels by ELISA method and Fourier Transform Infrared (FTIR). Data of CAand CO levels were statistically analyzed to determine the difference between pre slaughter andslaughter conditions. FTIR spectra were analyzed using chemo-metrics software. The results showedthat the levels of urinary cortisol were 2.12±1.68 ng/dl of pre-slaughter and 7.58±3.89 ng/dl ofslaughtered and the levels of urinary catecholamine in pre slaughter and slaughter were 3.07±2.05 and4.15±2.68 ng/dl respectively. The results showed a correlation between the FTIR spectra and the resultsof ELISA analysis. FTIR spectrums were distributed in different quadrants, this was caused bydifferences of CA and CO levels between pre-slaughter and slaughtered. It can be concluded that FTIRcan be supposed to analyze the status of stress in animals, especially in cattle.

Abstract

The aims of the research were to confirm the short estrous cycles and determine the blood level ofestradiol 17-β and ovarian follicukar dynamics in these cases. The research was conducted using sevenBali cattle, approximately 2 years of age, kept in healthy condition with normal estrous cycles.Observation of estrus symptoms was performed daily. Ovarian follicles was examined and measuredusing ultrasonography started at the estrus day. Blood samples were collected from jugular vein, bloodsample collection and ultrasonographical examination of the ovaries were performed daily in the sametime. Serum level of estradiol 17-β was performed using EIA. The short cycle estrus were observed in 4Bali cattle (n=7) among natural estrous cycle. They have only one wave ovarian follicular developmentwhereas the maximal size of ovarian follicles ovulation likes the normal cycle The duration of shortestrous cycle was 7-10 days with normal usual estrus behavior. The peak of blood serum level was107.77 ± 55.94 pg/ml when the diameter dominant follicle of short estrous cycle was reached 10.5 ±0.38 mm. It can be concluded that the short estrous cycles may occur in Bali cattle after puberty amongnormal cycles.
