The effect of photoperiod on partition of digested energy between fat and protein synthesis : a dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln College
Abstract
Thirty Dorset Down x (Border Leicester x Corriedale) female lambs were used to determine the effect of two fixed photoperiods (16L:8D and 8L:16D) on growth rate and body composition. Pair-feeding and controlled conditions were maintained for 91 days. Comparative slaughter procedures
were used to determine changes in body composition. No significant
treatment differences were detected (P > 0.05). However trends observed
indicate the existence of a photoperiod effect on growth. Sheep in the
long photoperiod (16L:8D) gained bodyweight slightly faster and had a
higher protein content of gain.... [Show full abstract]
