Studies of interspecific hybridization between perennial Trifolium species and Trifolium Pratense L.

Bastien, Denis Jean-Marie. January 1965 (has links)
Red clover has always occupied an important position anong the forage legumes grown in Canada and the United States. However, the acreage devoted to red clover (Trifolium pratense L.) has declined due to weaknesses in some important agronomic characteristics. A main weakness is its survival two or more winters. The winter survival of red clover depends, of course, on many different factors. Common objectives in breeding are (1) greater winter hardiness, (2) better disease resistance, and (3) a more perennial growth habit. [...]

A comparative study of techniques for the nutritive evaluation of grazed forage.

Perera, Michael Ernest. January 1966 (has links)
Several techniques were compared for the nutritive evaluation of grazed forage. It was shown that esophageal samples were more representative of the grazing animal's diet than clipped samples. High drying temperature affected the intake values obtained by different indicator methods. Results showed that the chromogen ratio and the lignin ratio methods could give relatively accurate and similar intake values provided the correct MEC combinations for chromogen and VanSoest's procedure for lignin were used. In vitro cellulose digestibility and animal behaviour studies suggested that the NVI computed using the lignin ratio method gave more meaningful results particularly for aftermath forages. In vivo and in vitro studies indicated that the first growth forage up to the midbloom stage was superior in feeding value to the best aftermath forage. As measured by the NVI the feeding value of pasture managed differently appeared to be affected more by stocking rate than by the method of grazing. [...]
