Obračun ekonomskih vrednosti za rast, reprodukciju i osobine vune ovaca rase makui korišćenjem 'Ecoweight' softvera
Calculating economic weights for growth, reproduction and wool traits in Makui sheep breed by Ecoweight software
Sažetak
Parametri proizvodnje, reprodukcije, upravljanja i ekonomski parametri dobijeni iz podataka prikupljenih od 1993. do 2012. godine, u istraživačkoj stanici za Makui ovace pokrajine Zapadni Azerbejdžani u Iranu, su ocenjenivani u ovoj studiji. Osobine uključene u istraživanje su osobine plodnosti, stopa jagnjenja, težine jagnjadi od rođenja do kraja perioda, stopa preživljavanje jagnjadi, proizvodnja vune, prosečni dnevni prirast i proizvodnja mleka. Sadašnja vrednost profita izračunava se kao razlika između ukupnih prihoda i ukupnih troškova po ovci godišnje. Numeričko izvođenje svake posmatrane osobine je izračunato povećavanjem i smanjivanjem prosečne vrednosti osobine, dok su ostale osobine zadržane u prosečnoj vrednosti. Prvo su svi troškovi, prihodi, profit i struktura stado utvrđeni, onda internirani ulazni inputi i pokrenut softver ECOWEIGHT. Rezultati su pokazali da se ekonomske vrednosti po jedinici povećavaju u osobinama težina na rođenju, dnevni prirasti od rođenja do odbijanju, dnevni prirasta od odbijanja do kraja perioda, stope koncepcije ovaca, veličina legla, preživljavanje jagnjadi, životni vek ovaca, prinos mleka i vune prinos za 0,66; 0.51; 0,03; 0,66; 0,25; 0,85; 0,93; 0,53 i 1, respektivno. Odgajivački cilj za ovce rase Makui je prinos vune, životni vek, preživaljavanje jagnjadi kod odbijanja, stope koncepcije ovaca, telesna masa, prinos mleka, dnevni prirast od rođenja do odbijanja, veličina legla, dnevni prirasta od odbijanja do kraja perioda.
Abstract
Production, reproduction, management and economical parameters obtained from data collected from 1993 to 2012 Makui sheep research station of West Azerbaijan province in Iran were evaluated in the present study. Traits included of fertility, pregnancy rate, lamb weights from birth to the end of period, survival rate of lambs, wool production weight, average daily gain and milk production. The present value of profit computed as the difference between total revenues and total costs per ewe per year. The numeric derivation of each considered trait is calculated by increasing and decreasing the average value of the trait while was kept the other characters in the average. First all costs, revenues, profits and flock structure determined then interned input files and running the software ECOWEIGHT. The results showed that economic values per unit increase in the traits of birth weight, daily gain from birth until weaning, daily gain from weaning until end of period, conception rates ewes, little size, lamb survival, lifetime for ewes, milk yield and wool yield were 0.66, 0.51, 0.03, 0.66, 0.25, 0.85, 0.93, 0.53 and 1, respectively. Breeding objective in Makui sheep breed were productive wool yield, lifetime, lamb survival at weaning, conception rates ewes, birth weight, milk yield, daily gain from birth until weaning, little size, daily gain from weaning until end of period.
