Second and third group was administered with NHH 44Bt-Cotton seedsand NHH 44Non Bt-Cotton seeds at the dose level of 1000 mg/kg B.wt.respectively.The rats were observed daily <strong>for</strong> behaviour, appearance and toxicologicalsigns and symptoms, if any.Page 12 of 93

No toxic signs and symptoms were noticed in any of thetwo dose groups and the control group of animals.Mean body weightsNo significant differences were observed in the body weight gain(Appendix -1) pattern of the test groups when compared to the controlgroup of animals.Feed ConsumptionThe feed consumed by the rats in all the test groups was similar to thatconsumed by the animals of control group (Appendix-2).Haematological evaluationsNo significant changes were noted among the test groups and control groupof animals with respect to haematological findings (Appendix-3) as all theparameters fell within the accepted limits of normal variations <strong>for</strong> albinorats.Page 18 of 93

As there were nosignificant changes in the organ weights of the test animals, when comparedwith organ weights of control group animals, the test substance (NHH 44 Bt-Cotton seeds and NHH 44 Non Bt-Cotton seeds) was failing to suggest anyspecific target organ.Necropsy examinationsNecropsy examination of animals did not reveal any significant changes inboth the test groups i.e. NHH 44 Bt-Cotton seeds and NHH 44 Non Bt-Cotton seeds at the level of 1000 mg/kg B.wt when compared to its controlcounterparts, as shown in Appendix 6.Histopathological examinationNo significant histopathological changes (Appendix-7) were noticed in theanimals of NHH 44 Bt-Cotton seeds and NHH 44 Non Bt-Cotton seedsdosed at 1000 mg/kg B.wt when compared to its control counterparts.Page 19 of 93
