The Difference

Cytogenetic analysis was made of 1466 chick embryos at one day of incubation. The embryos were from reciprocal crosses of two genetically diverse stocks (G1) and from matings among resulting crossbreds (G2). The overall frequency of heteroploidy was 4.6% in G1 and 5.8% in G2. The difference was not significant but the difference in frequency of triploid embryos (0.5% and 3.1%) was significant. This difference was attributed to the younger age of dams of the group with high frequency of triploidy. Furthermore, the same group of dams produced more triploid embryos when commencing their laying cycle at 19-22 weeks of age than at subsequent ages, 23-27 weeks of age, when their laying cycle had stabilized. The gonosomic complement of 54 triploid embryos was 25 ZZZ: 22 ZWW: 7 ZZW, indicating that about 80% result from failure of meiosis II of oogenesis.

The present study was designed to assess the teratological effects of Indoxacarb on chick embryos (Gallus gallus domesticus) by administering different doses of commercial Indoxacarb (0.5, 1.0 and 1.5ml/1000ml/egg, in three experimental groups B, C and D) injected into the yolk sac of eggs before incubation. Embryos were recovered at day 12 of incubation. The mortality rate gradually increased from lower to higher doses. A total of twelve morphometric parameters viz., wet body weight, crown rump length, anterior posterior head diameter, eye diameter, beak length, neck length, humerus length, radius and ulna length, metacarpus length, femur length, fibula length and metatarsus length were recorded and compared with control group. These quantitative parameters indicated significant plessthan0.05) decrease in all treated groups compared to control group. While the qualitative anomalies such as microcephaly, hydrocephaly, edematous swelling, hematoma formation, abnormal body coloration, anophthalmia, microphthalmia, deformed beak, agnathia, wry neck, micromelia, amelia, omphalocele and ectopia cardis were also recorded in treated groups as compared to untreated groups. Therefore, it is concluded that Indoxacarb has potentially harmful effects on the development of avian embryos even at very low dose concentration. Hence, due to toxicity of this pesticide it must be used with utmost caution.
