Abstract

An experiment was conducted to determine the effect of egg weight on hatching weight and incubation period in Giant African land snail. A total of 30 Archachatina marginata eggs comprising of four weight range categories (1.24-1.55, 1.56-2.14, 2.15-2.83 and 2.84-3.20 g) were obtained from Dams of different body weight ranges ( 100g-150g, 151-200g, 201- 250g) from Snail Physiology Research Unit of the College of Animal Science and Livestock Production, Federal University of Agriculture, Abeokuta, Nigeria. Eggs were incubated, after which both incubation period and hatching weight after hatching were monitored. Results obtained showed that egg weight group had significant effect (P<0.001) on hatching weight. Egg weight with weight range of 2.84-3.20 had the highest hatching weight, followed by 2.15-2.14 while other two (1.24-1.55 and 1.56-2.14 g) were not significantly different from each other. Furthermore, egg weight had no significant effect (P>0.05) on incubation period. Positive significant correlation was obtained between egg weight and hatching weight, and also dam weight and hatching weight. It was concluded that egg weight had effect on hatching weight of eggs. It was also discovered that egg weight had no meaningful effect on incubation period.
