Farm records between 2004 and 2011 were analyzed for selected parameters, particularly the calving rate, calving interval, daily weight gain of calves and calf mortality. Following the analysis, interventions were implemented in January 2012, which included the increased in pasture area from 399 to 441 acres followed by application of fertilizer. The selected breeder buffaloes were prepared for breeding by supplementing palm kernel cakebased feed at the rate of 1.5kg/animal/day for 2 weeks before breeder males were introduced at the rate of 1 male to 20 females. Prior to the intervention, proximate analysis of pasture revealed 7.6% protein content, 79% of breeder buffaloes were with body score of >3, the average calving rate was 22%, the calving interval was 24±11.2 months, average daily weight gain of calves was 0.89±0.21kg, the average birth weight was 28.31±3.26...

The product of GH gene hastens metabolism and promotes the growth of many organs and tissues especially bone, muscle and visceral organs. It also regulates growth, mammary gland development and lactation. Polymorphism in this gene is associated with increase in growth and development of many tissues in the body. Aim: The objective of this study was to investigate the polymorphism of bovine growth hormone (bGH) gene in buffalo bulls (Bubalus bubalis) using the PCR-RFLP (polymerase chain reaction–restriction fragment length polymorphism) technique. Design: Genomic DNA was extracted from a total of 10 bulls, consisting of Murrah – Swamp crossbred and pure Swamp buffalo bulls. A The 446 segment of the bGH gene was amplified. The DNA amplicons were detected in 2% agarose gel following 45 minutes of electrophoresis. They were thereafter digesting with AluI endonucle...

However, insufficiency of good quality oocytes has become one of the major constraints in producing embryos from IVP. Thus, a preliminary evaluation of ovaries could provide information for further experiment regarding IVP of cattle embryos. The objective of the present study was to evaluate the morphology of ovaries from different breed of cattle, including surface follicles and follicular health status. Thirty two (32) ovaries from Kedah-Kelantan breed and 32 ovaries from crossbred cows were collected from an abattoir in Taiping, Perak. Follicles visible on the surface of each ovary were counted and the weight, length and width of the ovaries were measured. The ovaries were then fixed and processed for microscopic evaluation, where the number of healthy and atretic follicles were counted. The mean ovarian weight, length, width and number o...

Metabolic energy budgeting (MEB) was introduced to assess feed conversion efficiency (FCE) of a cut-and-carry feedlot cattle farming system at SPT Tawau, Sabah and its correlations with rainfall, Nitrogen (N) application, and mobilised body energy (MELWL) were assessed. The results indicated that there is a trend that high farm rainfall, N application, and MELWL will improve FCE. The relationship, however, is complex where all three variables as well as the farm management procedures may act in synergy. High N application during low rainfall, for example, will not lead to high FCE, but when rainfall increases, the benefit of the N added will be apparent. High MELWL will lead to low FCE, but with nutrient correction (with supplement), the production cycle that has high MELWL may yield a better overall FCE. It is recommended that more research be done to establish farm management guidelines with ...

Farm records between 2004 and 2011 were analysed for selected parameters, particularly calving rate, calving interval, average daily gain of calves and calf mortality. Following the analysis, interventions were implemented in January 2012, which included increase in pasture area from 399 to 441 acres followed by application of organic fertiliser. The selected breeder buffaloes were prepared for breeding by supplementing palm kernel cake-based feed at the rate of 1.5 kg/animal/day for two weeks before breeder males were introduced at the rate of one male to 20 females. Weaning age was reduced from six to three months. Prior to the intervention, proximate analysis of pasture revealed 7.6% crude protein content; approximately 79% of breeder buffaloes were found with a body score of >3; the average annual calving rate was 22%; the calving interval was 24±11.2 months; a...

Thus, a study was conducted to perform metabolic energy budgeting at SPT 16 Tawau to assess the feed demand and supply of the said system. Available data were retrieved from 2008 to 2013, analysed and evaluated to identify the feed supply components of the system. The average herbage consumed in the system, expressed in proportion to the cut-and-carry paddocks, was 6.22 t DM ha –1 yr –1 . In herbage equivalent, the average concentrate consumed and feed loss as live weight loss energy were respectively 1.80 t DM ha –1 yr –1 and 0.59 t DM ha –1 yr –1 . It appears that the amount of herbage consumed is lower than the potential dry matter production of around 21.3 t DM ha -1 yr -1 based on the availability of light and rainfall for the region. The amount of concentrate consumed is relatively low, and this could be replaced with wellcultivated and high quality herbage to reduce overall feed co...

A domesticated form of Banteng, called ‘Bali cattle’ considered to be the same species and occurs widely in Indonesia and has been introduced to other areas of the world. Banteng cattle were classified as endangered species by IUCN Red List. In the past few years an effort has been made by Department of Veterinary Services and Animal Industry (DVSAI) Sabah, Malaysia in Banteng research for conservation and breeding program purposes. Electroejaculation technique was applied on fifteen Banteng cattle for semen collection. Collected fresh semen then analyzed for semen volume, pH, sperm concentration and motility. The objective of this study was to determine the fresh semen quality of domesticated Banteng cattle reared in Sabah, Malaysia. Results in this study show the semen volume was between 2.2 to 11.5 ml (mean; 6.28±2.3 ml), pH 6.63 to 7.48 (mean;7.01±0.24), sperm concentration between 30 to 470 x 106 spe...

The farm was practicing extensive grazing system without supplementation since 2010 to 2011. In early 2012, the farm had implemented a new intervention to improve the growth performance via improving the feed and the feeding management. Farm records between 2010 to 2015 were analyzed for growth performance and partial budget analysis. So far, there is no comparative study done between Swamp and Murrah crossbred buffaloes in Malaysia. Therefore, in the present study, we aimed to study the differences in the biological and economical performances between Swamp and crossbred buffaloes in Malaysia. With a new intervention, a significant improvement was reported of the number of calves born, average birth weight, and reduced percentage of calf mortality rate, calving interval, and weaning age. Crossbred buffalo showed dominance in biological performance in terms of...

However, there is limited information about the effects of these supplements on the performance of buffaloes. This study evaluates the effects of concentrate and bypass fat supplementations on the growth performance, blood metabolites, and feeding cost of Murrah cross and Swamp buffaloes. Following diet supplementation, the feed intake, body weight, and body condition score were significantly improved without any side effects on the blood metabolites of both buffalo breeds. Although the mixture of concentrate and bypass fat supplement (26:4) used in this study was found to increase the cost of feed, overall, it resulted in a greater return. Abstract This study investigates the effects of supplementation of the basal diet with concentrate and rumen bypass fat on the dry matter intake (DMI), growth performance, blood metabolites and hormona...

In Sabah, a genetic improvement program on Brahman cattle was initiated at Livestock Breeding Centre, Tawau using Estimated Breeding Value (EBV) with the collaboration with Australian Brahman Breeders' Association. The objectives of this study were to evaluate the performances of the progeny from the Brahman cattle genetic improvement program in Sabah. There were 120 Brahman cows used in the breeding program. The cows were divided into five herds and each herd was mated with a single pedigree Brahman sire with known EBV. The average body weights of the male calves are heavier than the female calves at all stages of growth. The average weight of the male calves were 179.1; 203.2; and 259.1 kg and the female calves were 180.1; 197.6; and 246.4 kg at 200, 400 and 600 day respectively. The average age at first calving is 1290.8 days with ranges from 1190.9 to 1427.0 days. There was no significant different in the age at first calving among the heifers from all the sires. In addition, the time taken for the male calves to reach weight between 300 to 350 kg is on average 723.7 days and the average weight at that age was on average 316.67 kg. Indeed, the performances of the Brahman cattle using EBV technology in this study had shown big potential to be implemented in wider scale in Malaysia as to increase beef production.

In order to improve the performance of the Asian water buffalo, the optimal balance of all nutrients, including energy and protein, are important as macronutrients. Dietary supplementation is one of the alternatives to enhance the essential nutrient content in the buffalo diet and to improve the rumen metabolism of the animal. Researchers have found that supplementation of concentrate and rumen bypass fat could change growth performance and carcass traits without causing any adverse effects on the buffalo growth. Some studies showed that dry matter intake, body condition score and some blood parameters and hormones related to growth responded positively to concentrate and rumen bypass fat supplementation. In addition, changes of feeding management ...

The current study examined the effect a mixture of 4% bypass fat and 26% concentrate supplementations in buffalo basal diet had on both the carcass characteristics and the proximate and fatty acid composition in longissimus thoracis et lumborum (LTL), supraspinatus (SS) and semitendinosus (ST) muscles of Murrah cross and swamp buffaloes. In addition, profit and loss analyses were performed to determine the profitability. This study employed a completely randomized 2 × 2 factorial arrangement with two diets, two breeds and four replicates per treatment. A total of sixteen buffaloes (eight buffaloes per breed, bodyweight 98.64 ± 1.93 kg) were randomly assigned into two dietary groups. The first group was given Diet A, which consisted of 70% Brac...
