Contemporary aspects in assessment of protein needs in dairy cows / Savremeni aspekti u normiranju potreba u proteinima za krave muzare
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2003)
The aim of meeting protein needs in dairy cows is to provide sufficient degradable proteins, which are optimally used in the rumen, to provide the required level of productivity with a minimal amount of crude protein in ...
Factors affecting dry matter intake and its prediction for Holstein cows / Faktori koji utiču na konzumiranje suve materije i njeno predviđanje za krave Holštajn rase
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2003)
Many factors affects dry matter intake (DMI). Individual theories based on physical fill of the reticulorumen, metabolic-feedback factors, or oxygen consumption have been proposed to determine and predict DMI (NRC, 2001). ...
Weed resistance to herbicides states: Causes and possibilities of preventive resistance / Rezistentnost korova na herbicide - stanje, uzroci nastanka i mogućnosti sprečavanja pojave rezistentnosti
(Privredni pregled, Beograd, 2003)
Resistance occurs as a result of heritable changes to biochemical processes that enable plant survival when treated with a herbicide. Resistance can result from changes to the herbicides target site such that binding of ...
Study of the project 'optimization and standardization of native technology for Pirot kachkaval - hard cheese of protected brand and origin' / Optimizacija i standardizacija autohtone tehnologije pirotskog kačkavalja sa zaštitom oznake porekla
(Institut za stočarstvo, Beograd, 2003)
Based on results of performed investigations and analysis of existing conditions relating to technological process in production of kachkaval, we propose the following: To determine the causes of disturbed secretion in ...
Changes in body proportion of roe deer with age / Promene u telesnoj razvijenost srneće divljači sa uzrastom
(Institut za stočarstvo, Beograd, 2003)
The aim of the present study was to estimate the development of body and some body parts and internal organs of roe deer, from 1 year of age (fawn) to 2-3 years of age (Buck). Average body mass of fawn was 16.6 kg and of ...
Morpho-physiological studies in held-grown maize genotypes selected for abscisic acid content / Morfo-fiziološka ispitivanja genotipova kukuruza gajenih u polju i selekcionisanih na osnovu sadržaja abscisinske kiseline
(Unija bioloških naučnih društava Jugoslavije, Beograd, 2003)
Selection program to produce closely related genotypes varying in the leaf content of plant hormone abscisic acid (ABA) was done with maize to test morpho-physiological consequences of this genetic modification. The cross ...
Partial drying of tomato root-zone: physiological effects and implications for solute transport mechanisms
(Oxford Univ Press, Oxford, 2003)
Regulation of voltage in the single-phase asynchronous generator with a double coil on the stator / Regulacija napona jednofaznog asinhronog generatora sa dva namotaja na statoru
(Naučno društvo za pogonske mašine, traktore i održavanje, Novi Sad i Univerzitet u Novom Sadu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Novi Sad, 2003)
The paper describes the problem of voltage regulation in the single-phase asynchronous generator with a double coil on the stator, which is particularly suitable for the cases where low output voltages are requested. This ...
