  • The meta-analysis of sheep body weight prediction with body measurement, breed and sex categories for practical livestock management purposes
    Millawati Gani, K. Karuppannan, Mohd Firdaus Ariff Abdul Razak and Ahmad Azhar Mohammed

    Elephant Endotheliotropic Herpesvirus (EEHV) is a highly destructive viral disease affecting both Asian and African elephants, posing a threat in captivity and the wild. Despite habitat loss, poaching, and human-elephant conflict being major concerns, EEHV emerges as a significant threat to elephant species' long-term survival. Until now, no reported cases of EEHV have been documented in Malaysia, particularly in Peninsular Malaysia. This raises questions about whether the absence of report is due to the virus's actual absence or a lack of awareness. Wildlife disease surveillance programmed initiated EEHV screening in Asian elephant at National Elephant Conservation Centre (PKGK) which one of establish ex-situ facilities for elephant conservation in Peninsular Malaysia. Molecular detection approach by utilizing polymerase chain reaction amplification targeting polymerase U38 gene region revealed 12 individuals out of 33 captive Asian elephants was found EEHV-positive, spanning ages from 2 months to 15 years and both sexes. Phylogenetic analysis revealed distinct EEHV subtypes identified in this this study. Despite being EEHV-positive, the captive Asian elephants displayed good health, indicating asymptomatic infections of EEHV1A, EEHV4, and EEHV5. This marks the initial identification of EEHV and subclinical infections in captive elephants in Peninsular Malaysia, emphasizing the need for urgent and enhanced health care management to safeguard these magnificent animals in Peninsular Malaysia for better conservation management strategies in the future.

    Background and Aim: To achieve optimal feed efficiency in ruminants, especially Pesisir cattle, it is necessary to maintain a harmonious equilibrium between energy and protein levels within the rumen. Sulfur supplementation can potentially escalate the energy–protein balance in the rumen. The aim of this study was to explore the formulation of ruminant diets by synchronizing rumen degradable protein (RDP) and non-fiber carbohydrate (NFC) while adding sulfur minerals at different levels. Nutrient digestibility, NH3 concentration, volatile fatty acids (VFA) production, microbial protein synthesis (MPS), and methane gas production were assessed. Materials and Methods: We employed a randomized block design with a 2 × 2 × 3 factorial arrangement and examined diverse incubation periods of 6, 24, and 48 h. Treatment consisted of RDP (60% and 65%), NFC (35% and 40%), and sulfur (0%, 0.15%, and 0.3%) levels. In this study, the Tilley and Terry in vitro technique, which used Pesisir cattle’s rumen fluid, was employed to assess the digestibility of dry matter, organic matter, acid detergent fiber, neutral detergent fiber, and RDP-Rumen undegradable protein. In addition, it measures various rumen fluid attributes, including pH, NH3, VFA, MPS, and methane gas production. Results: Treatment with a coordinated combination of 65% RDP and 40% NFC combined with 0.15% sulfur supplement yielded significantly improved digestibility and notably reduced methane gas production (p < 0.05). Conclusion: The enhancement in digestibility and reduction in methane gas emissions can be attributed to the interaction of RDP, NFC, and sulfur. Feed digestibility was increased in the 65% RDP treatment with 40% NFC and 0.15% sulfur, along with a decrease in methane gas production. Keywords: degradable and undegradable protein, digestibility, non-fiber carbohydrate, rumen fermentation, sulfur.

    Cymbopogon nardus waste has potential as an ingredient of cattle diet. C. nardus waste requires feed processing to increase ruminal fermentation characteristics. This study has aimed to discover the effect of fermentation and ammoniation treatment of soaked and unsoaked C. nardus on in vitro ruminal fermentation characteristics and nutrient digestibility. Five experimental diets with four replications were evaluated in this study: Cymbopogon nardus (CNW) as control, unsoaked fermented CNW (FCNW1), soaked fermented CNW (FCNW2), unsoaked ammoniated CNW (ACNW1), and soaked ammoniated CNW (ACNW2). A randomized block design was used and followed by post hoc Tukey-HSD if there is a significant effect (P<0.05). The results showed that there was no significant effect (P>0.05) of soaked or unsoaked ammoniated and fermented CNW on in vitro dry matter digestibility (DMD) and organic digestibility (OMD). Meanwhile, there was significant effect (P<0.05) on in vitro digestibility of crude protein (CPD), ADF (ADFD), NDF (ADFD), cellulose (CLD), and hemicellulose (HCLD). There was also no significant effect (P>0.05) of soaked or unsoaked ammoniated and fermented CNW on in vitro ruminal fermentation characteristics (pH, NH3, and total VFA level). In conclusion, soaked ammoniated of C. nardus waste has potential as cattle diet because it has high value of in vitro digestibility of crude protein (56.81%), ADF (47.67%), NDF (48.68%), cellulose (47.19%), and hemicellulose (50.52%).

    The nutritional value of sago pith is limited due to its low protein content, making it less suitable for poultry feed. To increase the benefit values of the sago pith, it is necessary to process it through fermentation. The current study aimed to determine the effects of substrate composition and fermentation time of fermented sago (Metroxylon sagu) pith (SP) and Indigofera (Indigofera zollingeriana) leaves (IL) mixture using Rhizopus oligosporus as an inoculum on crude protein, crude fat and crude fiber content of fermented SP and IL, nitrogen retention, crude fiber digestibility, and energy metabolism in broiler chickens. The study was performed on 30 broiler chickens, average weighing ± 1.5 kg at 6 weeks of age, along with SP, IL, and R. oligosporus. This experiment was conducted using a randomized design in a 3×3 factorial with three replications. Substrate composition, or factor A, was made up of A1 (80% SP + 20% IL), A2 (60% SP + 40% IL), and A3 (50% SP + 50% IL). Fermentation time as Factor B entailed B1 (2 days), B2 (3 days), and B3 (4 days). The findings demonstrated a significant interaction between the time of fermentation and the composition of the substrate in relation to crude protein content, nitrogen retention, crude fat, crude fiber digestibility, and energy metabolism. It can be concluded that the composition of substrate 50% SP and 50% IL with 3 days of fermentation yielded the best result, with crude protein at 25.45%, nitrogen retention at 59.72%, crude fat at 0.020%, crude fiber at 6.40%, crude fiber digestibility at 57.34%, and metabolic energy at 2658.44 kcal/kg.

    Online Journal of Animal and Feed Research
    Present research aimed to increase soybean meal waste quality and nutrient by fermentation using different ratio of mixed fungus inoculum (Aspergillus ficuum and Neurospora crassa) and fermentation time. The primary materials were soybean meal waste (SMW), fungus Aspergillus ficuum and Neurospora crassa. The experiment applied a completely randomized design (CRD) with a 3 × 3 factorial pattern and three replications. Two treatments were given in this study, factor A (combination of A. ficuum and N. crassa), comprising of A1 (3:1), A2 (3:2), and A3 (3:3). Factor B (fermentation time) comprising of B1 (5 days), B2 (7 days), and B3 (9 days). The variance analysis exposed a highly significant interaction between factor A and factor B, and those factors also exposed a highly significant effect. The correlation between SMW crude protein and broiler nitrogen retention showed a positive trend, contrary SMW crude fiber content negatively affected crude fiber digestibility. In conclusion, the combination of A. ficuum and N. crassa (3:2) and seven days fermentation period showed optimal results as seen from 28.25% crude protein, 13.77% crude fibre, 61.16 nitrogen retention and 58.76% crude fibre digestibility of fermented SMW. Keywords: Aspergillus ficuum, Crude protein, Digestibility, Fermentation, Neurospora crassa.

    Citronella residues (CR) have the potential to be used as an alternative to the fiber diet of ruminants. This study reports on the effects of pre-ingestive CR using ammonia (4 % dry matter (DM)) and fermentation (6 % DM) on in vitro rumen fermentation, metabolism, and methane (CH4) production. Four CR levels of 0, 25, 75, and 100 % DM were used. Each level was repeated 3 times and a complete randomized design method was used. The results showed that pre-ingestive CR significantly increased the pH rumen fluid but decreased ammonia-nitrogen concentration, total iso-volatile fatty acid (iso-VFA) production, and protozoa population (p < 0.01). The pre-ingestive CR significantly decreased the acetic acid composition and rumen microbial protein synthesis (p < 0.05), and significantly increased the proportion of propionic acid, n-butyric acid, and iso-valeric acid (p < 0.05). The total VFA production and rumen CH4 production did not significantly change (p > 0.05). In conclusion, pre-ingestive CR was compatible as a basal diet for ruminants.

    Aim: The aim of this study was to evaluate the effects of various combinations of tropical grass-legume species in rations on the biohydrogenation (BH) activity of unsaturated fatty acids (FAs), C18:0 composition, and fermentation profile in an in vitro rumen system. Materials and Methods: Samples of the following five fodder plants were used: One species of grass (Pennisetum purpureum) and four species of tree legumes (Leucaena leucocephala, Gliricidia sepium, Calliandra calothyrsus, and Indigofera zollingeriana). The following eight experimental diets were evaluated: 50% P. purpureum + 50% L. leucocephala (LL I); 50% P. purpureum + 50% G. sepium (GS I); 50% P. purpureum + 50% C. calothyrsus (CC I); 50% P. purpureum + 50% I. zollingeriana (IZ I); 75% P. purpureum + 25% L. leucocephala (LL II); 75% P. purpureum + 25% G. sepium (GS II); 75% P. purpureum + 25% C. calothyrsus (CC II); and 75% P. purpureum + 25% I. zollingeriana (IZ II). Each ration was replicated 3 times. In vitro rumen incubation was performed for 48 h, according to the Tilley and Terry method. Determination of the FA profiles of the forage materials and rumen fluid samples was performed using gas chromatography. Results: The percentage of polyunsaturated FA (PUFA) in the forage materials ranged from 34.18% (P. purpureum) to 74.51% (C. calothyrsus). The percentage of monounsaturated FA (MUFA) ranged from 5.06% (P. purpureum) to 8.71% (L. leucocephala). The percentage of saturated FA (SFA) was the lowest at 19.12% (C. calothyrsus) and highest at 60.76% (P. purpureum). In vitro BH of C18:3 n-3, C18:2 n-6, C18:1 n-9, and C18 PUFA in the experimental diets ranged from 72% to 100%. The BH of C18:1 n-9 in GS I (80%) and IZ I (72%) was significantly different (p&lt;0.05). The percentage of C18:0 was 10-50% and significantly different (p&lt;0.05) among treatments, with the highest (of 50%) in GS II. No significant differences (p&gt;0.05) were observed in the fermentation parameters (pH, total volatile FAs, in vitro dry matter digestibility, and in vitro organic matter digestibility) among the treatments, except in NH3 concentration (p&lt;0.05). Conclusion: The various combinations of tropical legumes do not have significant inhibitory effects on the BH of C18:2 n-6, C18:3 n-3, and C18 PUFA after in vitro incubation for 48 h. Furthermore, an increase in the tropical legume ratio in the ration tends to suppress C18:0 formation after the fermentation simulation process. IZ I has the potential to reduce C18:1 n-9 (MUFA) disappearance and yield an ideal rumen fermentation profile.

    Insight Society
    Rice straw as ruminant feed has low digestibility makes ruminants difficult to digest. Since ammoniated rice straw can increase its digestibility, it is necessary to supplement it with Gliricidia sepium. This research aimed to determine the effect of Gliricidia sepium supplementation on decreasing methane gas production and improving nutrient digestibility in complete ration with ammoniated rice straw. The treatments of this research were: A = 40% ammoniated rice straw + 60% concentrate, B = 40% ammoniated rice straw + 50% concentrate + 10% Gliricidia sepium, C = 40% ammoniated rice straw + 40% concentrate + 20% Gliricidia sepium, D = 40% ammoniated rice straw + 30% concentrate + 30% Gliricidia sepium. This research showed supplementation of G. sepium significantly decreased methane gas production from 27.22 mM to 13.13 mM and the number of protozoa from 6.3 x 105 cell/ml rumen fluid to 4.7 x 105 cell/ml rumen fluid. Gliricidia sepium supplementation increased digestibility significantly (P 0.05) among treatments. Higher levels of G. sepium supplementation increased N-NH3 concentration from 7.33 mM to 10.50 mM and microbial protein synthesis from 74.33 mg/100ml rumen fluid to 108.25 mg/100ml rumen fluid. The treatment had a significant effect (P <0.05) on propionate production and the ratio of acetate: propionate. It can be concluded that 30% of Gliricidia sepium supplementation decreased methane gas production and the number of protozoa. Besides, 30% of Gliricidia sepium supplementation increased digestibility and rumen fermentation.

    IOP Publishing
    Abstract Legume is the best source of protein to ruminant. Tannin content in legumes can provide protein by pass for ruminant. This study was conducted to determine the effect supplementation of legumes (Leucaena leucocephala) as substitute of concentrate on nutrient digestibility and microbial protein synthesis of the completed feed based on ammoniated rice straw. The study was conducted in an in vitro used a randomized block design where there were 3 treatments dan 5 replications. The treatments were A. 40% ammoniated rice straw + 60% concentrate, B. 40% ammoniated rice straw + 50% concentrate + 10% Leucaena leucocephala, C. 40% ammoniated rice straw + 40% concentrate +10, + 20% Leucaena leucocephala. The results showed that the addition of of Leucaena leucocephala had increased the digestibility of DM, OM, CP and microbial protein synthesis (p&lt; 0.05). Increased doses of Leucaena leucocephala until 20% decreased digestion of nutrition compared with dose 10% but was still higher than control. In conclusion, the supplementation of Leucaena leucocephala on completed feed based on ammoniated rice straw in vitro can increase nutrient degradability. Supplementation of 10% and 20% Leucaena leucochepala were suitable to be used for further studies, therefore in vivo experiment is required to study the effects on animal production.

    Abstract. Makmur M, Zain M, Marlida Y, Khasrad, Jayanegara A. 2019. Fatty acids composition and biohydrogenation reduction agents of tropical forages. Biodiversitas 20: 1917-1922. The study was conducted to determine the composition of fatty acids, measured rumen biohydrogenation reduction agents (total phenols and total tannins) content and selected promising plants in various species of tropical forages. Ten species of tropical forages, namely, Panicum maximum, Cynodon plectostachyus, Pennisetum purpurephoides, Pennisetum purpureum, Brachiaria decumbens, Glyricidia sepium, Calliandra calothyrsus, Stylosanthes guaianensis, Leucaena leucocephala and Indigofera zollingeriana were used in this study. The fatty acids composition (% of total identified fatty acids) which were dominant in grasses were C18: 3n-3 (29%), C16: 0 (28%) and C18: 2n-6 (23%). Whereas in legumes, the significantly higher composition of fatty acids was C18: 3n-3 (42%) followed by C16: 0 (17%) and C18: 2n-6 (17%). The average poly-unsaturated fatty acids (PUFA) composition in grasses was relatively lower (44.6%) than legumes (59%). Likewise the content of total phenols and total tannins (g/100g DM) of grasses (0.91 and 0.41) and legumes (1.72 and 0.70). The selection of the forage plant species was based on the criteria of PUFA composition and biohydrogenation reduction agents using TOPSIS method. The results obtained show that B. decumbens (grass) and I. zollingeriana (legume) had the highest preference value of 0.74 and 0.87, respectively. In conclusion, B. decumbens and I. zollingeriana are forage species that have potential to provide healthier ruminant products.

    Legume is a feed ingredient that contains high protein for ruminants. The tannin content in legumes can provide a bypass protein for ruminants. This study was done to find out the effect of legume supplementation ( Leucaena leucocephala ) on fiber digestibility, characteristic rumen, protozoa population and methane production from total mixed ration (TMR) based on ammoniated rice straw. The study was conducted in vitro using a randomized block design with 3 treatments and 5 replications. The treatment was A. 40% ammoniated rice straw + 60% concentrate, B. 40% ammoniated rice straw + 50% concentrate + 10% L. leucocephala , C. 40% ammoniated rice straw + 40% concentrate +10, + 20% L.leucocephala .The results showed that the addition of L. leucocephala increased digestibility of NDF, ADF, and Cellulose,  RUP (rumen undegradable protein) and reduced protozoa population and methane production (p <0.05). Increased doses of L.leucocephala up to 20% reduce fiber digestibility of feed substances compared to a dose of 10% but are still higher than controls. The results of this study concluded that L.leucocephala supplementation in TMR based on ammoniated rice straw in vitro improved digestibility, fermentability, and reduced methane gas production. Supplementation of 10% and 20% L. leucocephala needs further research, to see the effect on livestock in vivo .
