  1. 21. Extrusion of grass silage and its effect on feed intake, milk production and ingestive behaviour of dairy cows

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Markos Managos; [2020]
    Keywords : extrusion; grass silage; dairy cows; milk production; milk composition; rumen pH; ingestive behaviour;

    Abstract : Grass and clover ley is the main forage crop in Sweden, however, its restrictive role in feed intake limits the total amount included in the diet of a dairy cow. This study examined the effect of extrusion on grass silage intake, milk production, ingestive behaviour and rumen pH. READ MORE

  3. 22. The digesta passage rate among dairy cows with different abilities to consume large quantities of roughage : its impact on the milk production, and the reliability of the chemical fibre marker

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Maria Elisabeth Eklund; [2020]
    Keywords : chemical markers; chromium; chromium mordanted fibre; cobalt; concen-trate level; EDTA; iNDF; mean re-tention time; ethylenediaminetetraacetic acid; forage consumption; indigestible neutral detergent fibre; liquid digesta phase; MRT; rumen evacuation; sol;

    Abstract : The objectives of the present master thesis were to investigate the passage rate among lactating Holstein and Swedish red dairy cows to investigate the hypotheses of: 1) The cows’ individual total mean retention time (TMRT) has a negative relationship to the cows’ individual forage intake capacity. 2) A reduced TMRT contributes to a reduced feed efficiency, but a higher milk yield.

    Abstract : Plastproduktionen har ökat avsevärt sedan 1950-talet, och dessvärre hamnar allt för stor del av plasten i naturen. På grund av plasters egenskaper kan det ta flera sekel innan de bryts ned, och idag befarar forskarna att det kan komma att finnas mer plast i haven än vad det kommer finnas fisk – redan år 2050.
