Napier grass (Pennisetum purpureum) has been the most promisingand high yielding fodder giving dry matter yields. This experiment was conducted to determine the effect of cutting intervals on the yield and nutrient composition of six cultivars of Napier grass (Pennisetum purpureum) which is 3rd Generation Napier, India Napier, Kobe Napier, Red Napier, Taiwan Napier and Zanzibar Napier. The grasses were cut close to the ground levelto get a uniform stand on day 70 after planting and the cutting intervals were at 35 and 42 days and carried out for 3 times.After each harvest, the rates of maintenance fertiliser used were 150 kg of nitrogen, 60 kg of phosphorus and 100 kg of potassium per hectare per year. Harvested plant material was weighed, pre-dried in a forced-air drying oven at 60 °C overnight before grinding. Ground samples were used to determine dry matter (DM), crude protein (CP), crude fibre (CF) and metabolised energy. The data were analysed using Statistical Analysis System (SAS™) followed by Tukey’s post-hoc test. AP value of less than 0.05 (p<0.05) are considered statistically significant. Results showed that increasing the cutting interval (i.e. advancing age of maturity) increased dry matter and crude fibre significantly.However, in terms of nutrient content, crude protein and metabolised energy percentage was markedly decreased as thecutting interval increased. From the results presented, it is clear that cutting a stand of Napier grass at 35 days will achieve greater yield and nutrient content.

The objective of the study was to establish the baseline values for blood and coagulation parameters in normal and healthy rusa deer (Rusa timorensis) of different ages and sexes. The samplepopulation consists of 40 rusa deer, divided into four groups of (i) juvenile males (ii) juvenile females (iii) adult males and (iv) adult females. The findings showed significant (p<0.05) higher values in erythrocyte count, calcium concentration and prothrombin time in the adult males compared to adult female rusa deer. On the other hand, the total protein concentration was significantly higher in adult females than adult male deer. No significant differences in blood or coagulation parameters were observed between sexes in the juvenile deer. Between age group, the adult deer had significantly higher mean cell volume, plasma protein and globulin concentration than juvenile rusa deer. Thus, it is necessary to take into account the age and sex of the rusa deer when using blood reference values for the diagnosis of diseases or health assessment.

In Malaysia, Guinea grass (Megathrysus maximus) and Napier grass(Pennisetum purpureum) are considered as good palatable fodder for goats and have been used widely. The objective of this study is to evaluate the potential grasses for goats to have optimum growth performance and optimum feeding cost. Fourteen male Jamnapari goats with an average age of five months were used in this experiment. All animals were individually weighed anddivided equally (seven goats) into two treatment groups. Group 1 was fed with cut and carry Guinea grass while group 2 animals were fed cut and carry Napier grass, and both groups were given the same quality and quantity of PKC and molasses. There was no significant difference observed in the average final weight (AFW), average weight gain (AWG) and average daily gain (ADG) among the two dietary treatment group. However, dry matter intake (DMI) and feed conversion ratio (FCR) showed a significant difference. The group fed with Napier grass showed lower ADMI and FCR. From the viewpoint of economic evaluation, feeding Guinea grass and Napier grass as an animal feed is economincally viable for local farmers.

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.

Information on the nutritional content of animal feed is very important in improving milk production and the quality of milk produced. Data on the nutrition and nutritional quality of feed given to livestock are not comprehensively evaluated and recorded in any dairy farms in Johore. The objective of this study is to determine the nutritional content of selected feedstuffs, with production and quality of milk in selected dairy farms in Johore. Data were collected from 94 dairy farms during field visits through face-toface interviews. Feed samples collected were dairy cattle pellet, Napier grass, palm kernel cake, palm kernel expeller, soybean hull, corn, cassava peel and agricultural waste. Proximate analysis was performed using standard AOAC methods. The result of this study found that 67.0% of dairy farmers in Johore use Napier grass as the main source of fodder. The survey showed that 46% of the farmers in Johore give a suitable quantity of Napier grass based on body weight, while for milk production, the survey showed that 54 dairy farms in Johore produce less than 100 litres/day, 18 farms produce 101-200 litres/day, 12 farms produce 201-300 litres/day, and 10 farms produce more than 300 litres/day. The overall status of dairy farms in Johore shows that 60% of the farms produce an average of 5.1-10 litre milk per cow per day in which 92.5% of milk samples collected had acceptable Total Dissolved Solid values indicating good quality of milk production.
