Abstract

This study was conducted to determine the effect of various calcium and phosphorus levels on theproduction performance of Bantul Duck. A total of 270 female ducks, 26 weeks age, were used in thestudy with a 3x3 factorial treatment, which is a combination of three levels of Ca: 3.75; 3.25 and 2.75%and three levels of P: 0.45, 0.35 and 0.25%. Each treatment occupied three replication cages, each ofwhich consisted of 10 ducks. The experiment was conducted for 12 weeks.. Data recorded were: (a) feedintake (g/duck/day), (b) egg production (% HDA), and (c) feed conversion. All quantitative dataobtained during the study were analyzed by analysis of variance (ANOVA) using SPSS computerprogram. The results of the variables recorded did not show significantly difference. Increasing Ca levelon feed showed an increasing trend of egg production. The average feed consumption ranged at 151-159g/duck/day; egg production was 75-84%, and the feed conversion was 184-212 g/egg.

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 study was aimed to evaluate the effect of age on the serum metabolite of female Brahman crossbred cattle raised extensively under the cattle-oil palm integrated system for 3 months. Thirty calves aged 3-6 months, 30 heifers aged 12-18 months, and 30 cows aged 48 months which were clinically healthy were selected and used in this study. Blood samples were collected from coccygeal vein. The serum was separated by centrifugation and stored at -20oC until the time of analysis. Blood samples were collected from coccygeal vein as much as 4 mL. Serum metabolites were determined using an autoanalyzer (The Roche/Hitachi Cobas 6000 analyzer). Serum concentration of ALB, Ca, P, Na, K, and Cl in calves were higher than heifers and cows (P<0.05), while serum creatinine, total protein, blood urea nitrogen (BUN) and globulin concentration in cows were higher than those ofcalves (P<0.05). Serum glucose concentration in calves and heifer was higher than that in cows (P<0.05). It could be concluded that the age factor must be considered in the interpretation of the results of the examination of the serum metabolites of Brahman crossbred cattle raised extensively in oil palm plantations.
