In specific project orientiated experimental studies a herd of dwarf goats has been kept at Bio-Saline Research Substation (BSRS), Rakh Dera Chal, Lahore District; of Nuclear Institute for Agriculture and Biology (NIAB) comprised Kallar grass alongwith minor proportions of other fodder materials. Kallar grass is being grown at BSRS with the objective of reclamation and improvement of the salinity affected soil. A two year observation of production and growth of the herd under Substation conditions is being presented. At the beginning of observation period 43 adult population included 31 females, 10 males and two infertile females. Total number of pregnancies during observation period was 97, it included 3 abortions and 94 full term deliveries. Kidding included 40 single, 24 twin and 2 triplet births. Maximum number of deliveries were observed in June followed by in the month of October and November. High mortality was observed in winter and inclusively of kids.

The haemolymph proteins, glucose and lipids of different developmental stages of Lucilia cuprina were estimated quantitatively. Starting with the early second instar, the protein contents decreased gradually as the fly reached the late pupal stage. The glucose level increased prior to the each larval molt but decreased as the pupa grew old. The lipid contents were higher in the early second instar larvae and decreased prior to molting, but in the third instar the values were reversed and in pupa also this value increased with age.

Muscle of fresh water fish, Cyprinus carpio exposed to zinc chloride (50 µg/ml) for two different time periods (48 hours and 4 weeks) were analyzed for zinc toxicity. The zinc chloride treatment for 48 hours did not produce any significant alteration in muscle enzymes (GOT, GPT and LDH) activities except for CPK which was raised 54 and 59% after 24 and 48 hours of treatment, respectively. Glycogen content exhibit 104 and 54% increase after 24 and 48 hours of treatment, while the total proteins decreased significantly by 21 to 27% at 6, 12 and 48 hours of treatment. In 4 week long zinc chloride treatment almost all the biochemical parameters remained unaffected except for GOT activity which was inhibited 49% after 2 weeks and for FAA content that decreased 59% during 1st week of treatment.
