Estimation of mixer distribution trailer function quality JF-Stoll in preparation of TMR feed mixture for dairy cows

Abstract

Quality of TMR feed homogenization and distribution is analyzed in this paper. TMR feed mixture for lactating cows feeding was prepared in vertical mixer distribution trailer JF- Stoll VM 8 1S. The mixture was consisted of components that are defined for dairy cows in the first lactation phase, with the milk production of about 40 l/day. Physical and chemical parameters are analyzed according to the regulations of quality and other requirements for animal feeds (Official Journal of SRJ nr. 20/00 38/01), such as contents of moisture, ash, fats, cellulose, proteins and non nitrogen extractive matter. For sampling and analysis are applied standard and non standard methods.

U radu je analiziran kvalitet homogenizacije i distribucije TMR obroka za muzne krave koji je formiran u vertikalnoj mikser distributer prikolici JF-Stoll VM 8 1S. TMR obrok je sastavljen po recepturi za grla u muži u prvoj fazi laktacije sa proizvodnjom mleka od oko 40 l/dan. Analizirani su fizičko hemijski sastojci u skladu sa pravilnikom o kvalitetu i drugim zahtevima za hranu za životinje (sl. list SRJ br.20/00 38/01), kao što su sadržaj vlage, sadržaj pepela, sadržaj masti, sadržaj celuloze, sadržaj proteina, sadržaj bezazotnih ekstraktivnih materija. Za uzorkovanje i analizu su primenjene standardne i nestandardne metode.
