  1. 1. The cow eye : function and effect of light on milk yield

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

    Author : Hanna Tiilikainen; [2018]
    Keywords : cow-eye; light; photoperiod; milk-yield; prolactin; melatonin;

    Abstract : The purpose of this review was to study the cow’s eye physiology, focusing on how light affects the cow’s milk yield. It has been shown in studies that more hours of light per day (16 hours of light a day, as opposed to about 9-12 hours of light a day), increases milk yield for dairy cows. READ MORE

  5. 4. Mjölkureahalten som mått på vommikrobernas kväveförsörjning och kons miljöbelastning

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

    Author : Anna Strömgren; [2012]
    Keywords : mjölkurea; mjölkko; vommikrober; kväveförluster; fertilitet;

    Abstract : The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed.
