In a 2 X 2 factorial, randomized block experiment 12 Flemish X Danish cows with an initial mean weight of 423.8 kg and mean daily milk yield of 9.0 kg were fed for 8 weeks on Rhodes grass (Chloris gayana) pasture fertilized with 100 kg N/ha annually or on Rhodes grass and perennial soyabean (Glycine wightii) pasture continuously or in rotation. Mean daily milk yield on continuously grazed pasture was 8.9 and 7.2, and on rotationally grazed pasture 9.6 and 7.8 kg, respectively. Daily weight gain was 0.360 and 0.380 kg, and 0.767 and 0.066 kg. This abstract relates to the following species: |
