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.

A preliminary study on the effect of probiotics in fermented palm kernel meal (FPKM) and total mixed ration (TMR) to improve milk production in dairy cattle was carried out. TMR feeding enhances feed intake, improves the ecology of the rumen leading to stimulated microbial activity to digest more feed, and then finally increases productivity of the cows. Probiotics ofBacillus spp. was given through concentrate after a fermentation process for three days. The trial was carried out at the Dairy Unit, Veterinary Institute, Kluang, Johore. Twenty Mafriwal cows with low milk production were selected and divided into twoequivalent groups. Each group consisted of 10 cows. Group A were fed with TMR. Group B received TMR and 100 grams perhead/day FPKM (FPKM, probiotics Bacillus spp. and mollases). The cows were given TMR daily which consisted of 20 kg per headof fresh Napier grass, 5 kg per head palm kernel meal, 1 kg per head soya bean meal, 1 kg per head corn, 0.5 kg per head molassesand 0.5 kg per head of enalac. Feeding trial period was carried out for four weeks. Feed was given twice a day, morning and lateafternoon, meanwhile water was given adlibitum. Animals were given the same diet for seven days for an adaptation period.Milk was sampled twice a day for four weeks and were recorded accordingly. The average of daily and weekly milk productionwere calculated. The animals from Group B showed an improvement of milk production before trial to the fourth week from 5.2litres/head/day to 6.99 litres/head/day i.e. 14.80% to 34.44% as compared to Group A.

Palm kernel cake (PKC) has long been known to be an importantingredient for the formulation of animal feeds. However the recommended levels of inclusion seem to vary from one reporter to another. This factor is considered important especially when formulating feeds for nonruminant diets. The variation of its major constituents such as protein, fibre and fat contents is said to depend on the sources, oil removal technology and the efficiency of oil extraction from the kernel. For comparison,a set of compilation data of 300 local PKC samples from the past years on these basic nutritional constituents were studied.Majority of the samples analysed were from southern region of Peninsular Malaysia meant for animal feeds. Mean percentagevalues and their respective standard deviations were as follows; crude protein 16.1±1.65, crude fibre 19.3±4.22, crude ash5.9±2.48, ether extract 5.6±3.36, dry matter 91.3±2.65, and metabolisable energy 7.75 MJ/kg. The objective of the study was to observe the distribution pattern of these values compared to other surveys. From this study, the highest relative standarddeviation (RSD) reached 60% for ether extract, followed by ash 42.1%, and crude fibre 21.8%. From the variation point of view,periodical results for quality control of PKC must be initiated as an useful indicator for its accuracy of each diet formulation.

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.

This study was conducted to observe the occurrence of aflatoxin in chicken feed from Peninsular Malaysia. A total of 336 samples of chicken feed from Peninsular Malaysia were conveniently collected in this survey. The chicken feed represented the following three categories which are starter, grower and finisher. All samples werecollected from local poultry farms in East Coast Region (Kelantan, Terengganu, and Pahang), Northern Region (Perlis, Kedah, Penang, and Perak), Southern Region (Malacca, Johor) and Central Region (Selangor, Negeri Sembilan) of Peninsular Malaysia for a periodof six months (July-December 2015). Enzymelinked immunosorbent assay (ELISA) was used for screening of total aflatoxin (TA) in the samples. High performance liquid chromatography (HPLC) with fluorescence detector was used for determination of aflatoxin B and G. Moisture content of samples was determined using the hot airoven method (AOAC International, 2011). Overall, the incidence of positive TA >20 µg/kg in chicken feed is 14.9% (50 samples). The average level of TA was found significantly different between different states at p<0.05 for both broiler grower and finisher. Thechromatograph results showed that positive samples were found in broiler finisher from Kedah (94.6 µg/kg and 42.1 µg/kg) and Penang(56.4 µg/kg) with aflatoxin B1. In this study, the range of moisture content were around 6.5-27.3%. About 40% samples have more than12% moisture content. One of the predisposing factors for aflatoxin accumulation in chicken feed is moisture content. The results warrantthe need for surveillance and constant monitoring programmes for the prevention of aflatoxin incidence in poultry farms.

This study was conducted to investigate whether dietary enzymes alter the caecal microbial profile of broilers fed sorghum-based diets. Four sorghum-based diets (918 g sorghum/kg diet) were prepared. One was the control diet and three had enzymes (xylanase, phytase andprotease) added. Broilers, 35-day-old, were reared (8 birds/cage) in an environmentally controlled shed and randomly allocated to replicated (n=4) assay diets and free access to feed and water all time. On day-42, birds were euthanized and caecal contents collected, pooled on a per/pen basis and frozen (-20 °C). The DNA was extracted from caecal samples using a bead-beating protocol and the V2V3 regionof the bacterial 16S rRNA gene amplified by PCR. Amplicons were separated on sequence difference using Denaturing Gradient Gel Electrophoresis (DGGE) and microbial profiles generated and compared.The DGGE profiles, when analysed, indicated that there was approximately 80% similarity between caecal microflora in all types of the diet treatments. This suggests that there was no overalldifference between any of the profiles and therefore the addition of different types of feed enzymes in a sorghum-based diet had no impact on the overall composition of the broiler caecal microflora.

Cost of feed is one of the primary stumbling blocks for goat farming in Malaysia. Stage feeding was introduced as a method to formulate feed at minimum cost based on the requirement of different stages of production to improve overall farm productivity. A study was conducted to evaluate 5 feeding rations formulated based on the requirements of different production stages on Katjang-Boer crossbred. Ration formulated of creep feed (CF) for a period of 101d, starter grower (SG) (70d), grower finisher (GF) (98d), flushing feed (FF) (97d) and maintenance feed (MF) (155d) were compared with commercial feed (CCF and CMF) as control. Results showed a significantly higher (P<0.05 preweaning bodyweight of 12.83 ± 3.61 kg in CF at 101 days of age. Post weaning also achieved significantly higher bodyweight (P<0.05 of 22.20±2.78kg and 31.5±4.67 in SG (223 days) and GF (361 days) of age respectively. Feed cost per kg gain obtain in CF (RM5.68), SG (RM9.03) and GF (RM6.57) were lower compared to CCM of RM6.14, RM10.27 and 12.99 respectively. FF showed a significantly higher (P<0.05) average daily gain (ADG) of 67.01 ± 14.42 g while MF was able to maintain body weight at minimum cost. Stage feeding proved to be able to meet nutritional needs through significantly higher body weight in CF, SG, GF and FF as well as lower feed cost per kg gain rendering it as a more economical option.

To investigate premium palm kernel cake (PKC) based diet’s effect on amino acid digestibility, this study conducted a feeding trial. Four groups of 150 day-old broiler chickens in every group were given four isocaloric diets using these formulation: Diet 1 - commercial feed for both starter and grower phase Diet 2 - broiler feed that contains 30% PKC for starter phase + commercial grower, Diet 3 - commercial starter + broiler feed that contains 45% PKC for grower phase (and Diet 4 - broiler feed that contains 30% PKC for starter phase + broiler feed that contains 45 % premium PKC for grower phase. During the experiment’s day 31, bird faeces’ samples were collected based on group diets in order to estimate the availability of amino acid as well as the digestibility of amino acids using balance experiment. Ultra-Performance Liquid Chromatography with photo-diode array detector was used to analyse amino acid. The findings showed no significant difference in digestibility of amino acids with p<0.05 in the feed broiler chickens’ comparison with commercial feed in terms of different levels of PKC based diet. This study shows that by including 30-45% premium PKC in poultry diet, it could contribute as protein source in broiler feed production with suitable supplementation of essential amino acid. Further studies are encouraged to combine the analysis of excreta, ileal digesta and growth performance in order to achieve more concrete findings.

A study was conducted on 240 scavenging chickens randomly obtained from various districts from the state of Penang, Peninsular Malaysia. The chickens were closely examined for visible ectoparasites in the laboratory. The ectoparasites were collected using a blunt forceps and stored in universal bottles containing 70% ethanol. Ten species of ectoparasites were noted which consisted of five species of lice, two species of mites, two species of ticks and one species of chigger. The lice identifi ed were Menopon gallinae, Menacanthus pallidulus, Lipeurus caponis, Goniocotes gallinae and Goniodes dissimilis. These lice occurred in the fl uff of the feathers of the body especially the neck, back, abdomen and wings. The mites were Megninia sp. and Pterolichus sp. Examinations of the ears and combs revealed Haemaphysalis sp., the hard tick. Meanwhile, Ornithonyssus sp., the soft tick was found on feathers, whereas chigger, Leptotrombidium sp. was found attached to the skins. The study also revealed that M. gallinae was the most common ectoparasite with 76.7% occurrence, followed by Pterolichus sp. (69.6%), L. caponis (63.3%), M. pallidulus (41.7%), Leptotrombidium sp. (17.5%), G. gallinae (9.5%), Haemaphysalis sp. (6.7%), Megninia sp. (3.8%) and Ornithonyssus sp. (3.8%). The least common ectoparasite was G. dissimilis occurring in 2.1% of the chickens.

In vitro digestibility study was conducted to determine the effectsof supplementing fractionated Refined,Bleached and Deodorized Palm Stearin(RBDPST) on ruminal digestion. Fractionated RBDPST was soaked in incubation medium consisting of distilled water, buffer solution, trace element solution, micro and macro mineral solution, as well as rumen liquor that was collected from slaughtered cattle. This experiment was conducted at 39°C with an incubation period of 24 hours. Dried napier grass was used as control treatment. Gas producedwas recorded and collected to measure the methane gas produced. Methane gas produced from fractionated RBDPST was found to be relatively lower than control. This indicates that fractionated RBDPST had the ability to function as rumen bypass fat as it was not fully digested in the rumen.
