This study was done to assess oxidative stress and haematologicalparameters of twenty male goats aged between eight and 22 months of the West African Dwarf breed reared under twomanagement systems. Ten bucks were reared under an intensive system, and another 10 bucks reared under an extensivesystem were used. The Hb concentration obtained in both groups was significantly (p<0.05) higher in the intensively managedgoats (12.39±0.02 gm %) compared to the extensively managed group. The total erythrocyte count in intensive goats, 35.34±1.36×106/μl, was significantly (p<0.05) higher than the value recorded in the extensive group (30.01±1.41×106/μl). Therecorded leucocytes counts in intensive goats of 10.26±0.70×103/μl was significantly (p<0.05) lower than 12.38±1.23×103/μlrecorded in the extensively managed goat, while the calculated value of MCV in intensive goat (9.8±0.73 fl) was significantly(p<0.05) higher than the recorded value in extensive group. The obtained value of MCH was significantly higher (p<0.05) in theextensively managed goats. The recorded neutrophil value of 5.00±0.50×103/μl in extensively raised goats was significantly(p<0.05) higher than 3.70±0.20×103/μl obtained in the intensively raised group likewise the lymphocyte count of 5.60±0.08 ×103/μl in intensively raised goats was significantly (p<0.05) lower than the value obtained in the extensively raised goat. The neutrophil:lymphocyte ratio was significantly higher (p<0.05) in the extensive versus the intensive group viz. 0.75±0.03 asagainst 0.67±0.04. In the extensive group a higher malondialdehyde (MDA) value of 2.30±0.07 ng/ml was recorded and this was significantly (p<0.05) higher than the corresponding value of 1.28±0.11 ng/ml obtained in the intensively managed goats. The recorded value of superoxide dismutase, catalase and glutathione peroxidase was significantly (p<0.05) higher in theextensive group than those on the intensive group. The fragility test of the extensively managed goats shifts more towards rightand was significantly (p<0.05) highest at a sodium chloride concentration of 0.2-0.7% in extensively managed goats. It can beconcluded from the present study that the biomarkers of oxidative stress were higher in the extensively than the intensively managed goats.

Napier Pakchong (Cenchrus purpureus cv. Pakchong) is another cultivar of Napier grass which was introduced from Thailand. This cultivar is mostly adapted for local soil conditions in Malaysia, has high yield and relatively high protein content making Napier Pakchong suitable for ruminant feeding. This experiment was carried out to determine the dry matter yield and nutritive values of Napier Pakchong at three different cutting ages (6ᵗʰ, 7ᵗʰ and 8ᵗʰ weeks old). All plots underwent a standard preparation and basal fertilizers during grass establishment. The cutting treatments were carried out 3 times at the 6ᵗʰ, 7ᵗʰ and 8ᵗʰ weeks. After each harvest, the rates of maintenance fertilizer used were NPK 150:60:100 (kg/ha/year). The harvested forage was weighed and sent for dry matter yield and proximate analysis. The data were analysed by one way analysis of variance (ANOVA) using the programme of SAS (Package Version 9.4). The difference between treatment means was measured by Duncan’s Multiple Range Test (DMRT) at 5 % level of significance. The data showed that dry matter yield production increased in line with the cutting interval. Crude protein (CP) value declined as the harvesting interval increased. Even though the CP value declined, the CP percentage still fulfils the protein requirements for ruminants. It is suggested that Napier Pakchong harvested at 7th to 8th weeks due to optimum dry matter yield and nutritive value.
