Multiple ovulation and embryo transfer is one of the reproductivetechnologies which is important to increase animal production. In this case report, four cows were selected as donors while elevencows were selected as recipients. Both donors and recipients had undergone the same procedures and steps for multiple ovulation and embryo transfer (MOET), such as cow preparation, synchronisation and where only donor cows follow the superovulation protocol. Cows were artificially inseminated and the embryos were flushed and graded. Out of four selected cows for donor, one of them was pregnant and only two cows actuallyproduced the embryos. The recovery rate for the embryo collection was 70.1%, and from 13 embryos (including unfertilised ova), 84.6% of the embryos was classified as good quality and suitable for embryo transfer. The overall results showed that out of eight recipients, five cows were detected pregnant, a 62.5% pregnancy rate. The aim of this report is to describe the procedures aswell as the factors that affect the successful of the MOET programme.

Mootoo, Natasha | Munoz, Kirk | Ganesh, Thotta Narasimhalu | Hosein, Ansarah | Auguste, Tennille | Legall, Curtis
Ginger, about one year old domestic shorthaired cat with paresis was reported with constipation. Enema and laxatives prior to presentation was not effective. On palpation of the abdomen, a long tubular mass was palpated in the left caudal abdomen. Radiographic diagnosis of the megacolon was made and a subtotal colectomy was planned for the cat. A ventral mid-line celiotomy was made to explore the abdomen. Exploration revealed ascending, transverse and descending colon including the caecum found to be markedly distended due to faecal stasis. Following standard technique, a subtotal colectomy was performed. The cat recovered well after surgery without any complication. The owner reported that Ginger was doing well but died about seven months after surgery. Carcass was not available for necropsy. By clinical examination, diagnostic investigation and surgical exploration, other causes of megacolon were ruled out. The cat was about one year old with a short duration of illness. Without a definite history and by ruling out other causes, neurologic trauma was attributed as the probable cause of constipation and megacolon in the present case.

In Malaysia, helminthiasis due to strongyles such as Haemonchuscontortus and coccidiosis caused by Eimeria sp. have been reported to cause severe economic losses in small ruminants livestock industry. This paper reports the occurrence of gastrointestinal parasite infections on small ruminants situated in Seberang Perai Selatan district, Penang. Faecal samples were obtained from a total of 193 animals,randomly selected from 14 ruminant farms. The results of this survey indicates that helminthiasis and coccidiosis is rampant insheep and goat farms. The most common infections diagnosed were helminthiasis (77.72%) and coccidiosis (60.10%) followedby Moniezia sp. (5.18%). From this study, it shows that parasitic diseases can be managed by good animal husbandryin farms since high parasitic infections were observed in farms that were poorly managed based on nutrition, hygiene andbasic animal husbandry practices. The smallholders depended on health and extension services from the State Veterinary Department. A continuous monitoring of small ruminant farms by the Department of Veterinary Services will provide important information for assisting farmers with managing the spread of parasitic infections and maintaining the productivity of animals.
Afficher plus [+] Moins [-]A qualitative investigation of animal-to-human brucellosis knowledge among health workers in Kajiado North Sub-County, Kenya
2018
Maina, A. G. | Gatongi, P. M. | Nguhiu, P. N.
Animal-to-human brucellosis transmission methods in Kajiado NorthSub - Count y, Kenya are inadequately documented. The Sub- County’s main livelihood is livestock-keeping, putting it at risk to brucellosis infections. Objective of this study was to determine the knowledge of brucellosis among animal and humanhealth workers. These workers were stationed in Kajiado North Sub-County and were the key informants of this study from whom qualitative data was collected. The data was analysed based on emerging themes, e.g. brucellosis significance in the community, livestock birthing and milk hygiene. Results revealed that brucellosis a significant disease in the community, informants were knowledgeable on the need for pre-purchase livestock examination, the need for proper disposal of livestock abortive material and on good milk hygiene measures. However, it was found that not all had adequate knowledge about brucellosis transmission through livestock birthing. The results indicated that measures to control and prevent brucellosis transmission to man, and between animals were inadequate as health workers were unable to adequately advise the community. It is recommendedthat health workers should be trained on all methods of brucellosis transmission, especially transmission during livestock births.

Mauida, F. Hasoon, | Buktiar, Nader | Majed, H. Mohammed
Mesenchymal stem cells derived from bone marrow (BM-MSCs) havethe ability to differentiate into multiple cell lineages. Although the cultivation of these cells has led to a number of characterisation studies, some significant morphological and immunohistochemical properties are still lacking. In this study, isolation of BM-MSCs, morphological features, cell viability, immunophenotypic properties and cryopreservation of BM-MSCs wereexamined in detail. The results demonstrate that the cells isolated from BM-MSCs were plastic adherent and had fibroblastic spindle shape after three passages and get confluent monolayer cells 70-80% after 4-7 days post-subculture. Based on the cell viability analysis, the BM-MSCs showed an increase in cell viability starting from passage 1 until passage 10. Immunophenotypic analysis demonstrated that BM-MSCs were positivefor CD44 and CD105 and negative for CD34. Functional analysis of cryopreservation of BM-MSCs from P6 after 6 months expressed good proliferation rate and cell viability.

Infectious diseases of livestockare a major threat to global animal health and welfare and their effective control is crucialfor agronomic health, for safeguarding and securing national and international food supplies and for alleviating rural povertyin developing countries. Some devastating livestock diseases are endemic in many parts of the world and threats from old and new pathogens continue to emerge, with changes to global climate, agricultural practices and demography presenting conditions that are especially favourable for the spread of arthropod-borne diseases into new geographical areas. Zoonotic infections that are transmissible either directly or indirectly between animals and humans are on the increase and pose significant additional threats to human health and the current pandemic status of new influenza A (H1N1) is a topical example of the challenge presented by zoonotic viruses (Tomley and Shirley, 2009). Malaysia, being one of the members of the World Organisation forAnimal Health (OIE) which is responsible for setting standards for control of animal diseases. For year 2017, the list included 116 animal diseases, infections and infestations, many of which are zoonotic in nature. As such, this paper discusses the commonzoonotic infections diagnosed in the five Regional Veterinary Laboratories which are spread across the country and entrustedto carry out diagnostic tests to aid in the treatment and control of animal diseases. A total of almost half a million samples weretested comprising more than a million tests to help the Department of Veterinary Services control and eradicate economically important diseases to safeguard the animal population. Of these, zoonotic diseases comprise a small but significant entity which needs careful attention (Chandrawathani et al., 2017) Dora Tan (1981) reported that among the many zoonotic diseases prevalent in Malaysia, are leptospirosis, rabies, influenza, Japanese encephalitis, toxoplasmosis,ornithosis, Q fever and monkeypox which have been investigated at the lnstitute for Medical Research, Kuala Lumpur. The regional laboratories have full capability to conduct tests to confirm parasitic, viral and bacterial infections except for rabies andavian influenza, which was diagnosed in the Veterinary Research Institute. However, preliminary tests for avian influenza wascarried out in regional laboratories.

Suriaty R. | Mohd Hafiz A. R. | Halimaton Sa’adiah T. | Zawawi I.
Malin sheep is the indigenous sheep breed of Malaysia and mainlykept for meat production. A total of 48 individuals from the National Institute of Veterinary Biodiversity (NIVB) in Jerantut,Pahang were used. The objective of this study was to assess the genetic diversity in the Malin using microsatellite markers.Eleven microsatellite loci were successfully amplified in 48 Malin sheep. All loci were polymorphic. A total of 66 alleles were detected. The number of observed alleles per locus varied from 12 to 21, with mean observed number alleles per locus of15.18±4.58. The observed heterozygosity and expected heterozygosity were 0.0189±0.01 and 0.8989±0.01, respectively. The mean polymorphic information content (PIC) value was 0.8970±0.01, indicating that the used markers were highly informative and could be used in parentage identification. Tests of genotype frequencies for deviation from the Hardy-Weinberg equilibrium (HWE), at each locus revealed depature from HWE due to loss in heterozygotes by high levels of inbreeding. The average inbreeding value for the 11 markers investigated was0.9797±0.01 indicating a more homozygous nature of the population. This is the first report of microsatelitte based variations in Malin sheep breed and can be useful for development of a rational breeding strategy for genetic improvement of sheepin Malaysia which may benefit future conservation programmes.

Aswanimiyuni A. | Norlindawati A. P. | Azman A. | Haryani H. | Norfadzrin F.
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.
Afficher plus [+] Moins [-]Influence of applying effective microorganism (EM) in controlling ammonia and hydrogen sulphide from poultry manure
2018
Nurzillah M. | Norfadzrin F. | Haryani H.
Poultry layer houses are mostly open house system that generally faced with flies and odour and has become nuisance factors to society and the environment. This study was aimed to determine the effectiveness of applying EM in controlling pollutant gas emission at poultry layer house. A commercial poultry layer farmwas selected. Two treatments were carried out, the control without any application of microorganisms and the treated group with commercial microorganism application. Atmospheric ammonia and hydrogen sulphide were measured using a special instrument called ‘multi-gas detector’. The levels of ammonia and hydrogensulphide were measured twice a week. Odour production cannot be completely prevented on a farm. Therefore, most odour control methods are designed to keep or dissipate odours within the farm boundary, thus minimising odour complaints from surrounding neighbours. This paper reports that applying of effective microorganisms into the manure showed some positive influence in controlling atmospheric ammonia levels.
