Effects of different soil prepartion methods on the foliage N dynamics in Finnish boreal forests; 15N natural abundance isotopic method approach

Sah, S.P.; Ilvesniemi, H. (2008)

Effects of type of grass silage and level of concentrate on the flow of soluble non-ammonia nitrogen entering the omasum of dairy cows

Choi, Chang-Weon; Vanhatalo, Aila; Huhtanen, Pekka
Journal of animal and feed sciences : 1 (The Kielanowski Institute of Animal Physiology and Nutrition, 2003)

Four ruminally cannulated Finnish-Ayrshire dairy cows were used to study effects of type of grass silage (primary vs secondary) and level of concentrate supplementation on concentration and the flow of soluble non-ammonia ...

Leaching of nitrogen in barley, grass ley and fallow lysimeters

Yläranta, Toivo; Uusi-Kämppä, Jaana; Jaakkola, Antti
Agricultural Science in Finland : 4 (Agricultural Research Centre of Finland, The Scientific Agricultural Society of Finland, The Finnish Society of Dairy ScienceAgricultural Research Centre of FinlandThe Scientific Agricultural Society of Finland, 1993)

Nelivuotisessa lysimetrikokeessa tutkittiin typen huuhtoutumista savi- ja hiesumaasta, karkeasta hietamaasta ja saraturvemaasta. Koekasveina olivat Kustaa-ohra ja timotei-nurminataseos. Puolet viljellyistä lysimetreistä ...

Nitrogen isotopic discrimination as a biomarker of between-cow variation in the efficiency of nitrogen utilization for milk production: A meta-analysis

Correa-Luna, M.; Johansen, M.; Noziere, P.; Chantelauze, C.; Nasrollahi, S.M.; Lund, P.; Larsen, M.; Bayat, A.R.; Crompton, L.A.; Reynolds, C.K.; Froidmont, E.; Edouard, N.; Dewhurst, R.; Bahloul, L.; Martin, C.; Cantalapiedra-Hijar, G.
Journal of Dairy Science : 6 (American Dairy Science Association, 2022)

Estimating the efficiency of N utilization for milk production (MNE) of individual cows at a large scale is difficult, particularly because of the cost of measuring feed intake. Nitrogen isotopic discrimination (Δ15N) ...

Quantitation of the flow of soluble non-ammonia nitrogen entering the omasal canal of dairy cows fed grass silage based diets
