Abstract

The feedlot industry in Indonesia has developed very rapidly, along with the increase in meat consumption. Brahman Cross (BX) is an imported beef cattle from Australia which is widely used by feedloters as broodstock. Feedloter chooses BX cattle because besides the price is quite cheap, this breed also has a very good growth factor [1].In order to support the self-sufficient of beef meat, feedloters who imported BX from Australia have to conduct breeding program as part of the Ministry of Agriculture decree no. 02/PERMENTAN/PK.440/2/2017 related to the import of ruminants into Indonesia. BX Cattle is often crossed with other breeds through artificial insemination programs, in order to provide calving ease and to produce high-weight cattle.Beside the target to produce good body weight and average daily gain (ADG) of the calf from crossbreeding, the feedloters have also to manage the breeding efficiently by taking care of the reproductive disorder that might be affected the production.  Good reproductive efficiency will have a positive impact on increasing livestock production [2]. In various breeding programs, there are many factors that can affect the reproductive efficiency of cattle, such as reproductive disorders. Reproductive disorders can be a major economic problem in a farm. These reproductive health problems can be the bottleneck in the production process and productivity in the livestock sector [3].Therefore, this study will discuss the production performance in various cross-breed cattle and reproductive disorders in a feedlot breeding program.

Abstract

Banteng is considered as endangered species by the International Union for Conservation of Nature (IUCN). Banteng is currently distributed in Java, in Kalimantan [Indonesian Borneo], Sabah [part of Malaysian Borneo], Myanmar, Thailand, Cambodia and, probably Lao PDR and Vietnam (1). The populations in the Asian mainland have decreased by about 80% in the last decades. The total number of wild banteng is estimated to about 5,000-8,000 animals. No population has more than 500 animals, only a few have more than 50. Reasons for the population decline are reduction of habitat, poaching, hybridisation with domesticated cattle, and infections with cattle diseases (4).Since the wild population has been declining continously and the numbers of individual are getting smaller, therefore captive breeding is urgently needed in order to support the conservation of Banteng sustainably. Although breeding program of Banteng is important, but information about the reproductive biology of Banteng is very limited. Breeding programs in Banteng can be done by natural mating or using assisted reproductive technology such as artificial insemination (AI). The aplication of AI in Banteng can support Banteng conservation program in order to increase heterozygosity, prevent inbreeding and possible to use of the Banteng bulls from different facilities for AI of females in all breeding facilities of Banteng.AI applications require information on the estrous cycle and estrous signs to determine the precise AI time. Clinical signs of estrous in Banteng is difficult to observe, therefore determining the time of AI must be done through rectal palpation and ultrasonography. The objectives of  this research is to assess estrous cycle to determine time of insemination.

Abstract

Banteng (Bos javanicus) is listed as endangered species in IUCN Redlist. Only few thousand wild banteng survive and their numbers are decreasing as a result of hunting and the loss of habitat due to deforestation and conversion to agricultural land. One of the conservation measures is to preserve this species in ex-situ breeding center. The breeding centre with the largest number of individuals is Ragunan Zoo in Jakarta, with 21 animals. Despite those numbers of individuals available, the sex ratio was far from ideal at 16 males and five females. While in Taman Safari Prigen, there were with 16 individuals and a sex ratio of five males and 11 females [1] Since number of males are usually less than females, and also to avoid inbreeding in order to keep high heterozygosity population, therefore, assisted reproductive technology such as artificial insemination is considered to be necessary.For artificial insemination, semen collection sufficient quantitiy and quality of semen from males are needed. Thus, best semen collection method should be considered. Though transrectal massage procedure does not require the male to be anesthetized  prior to semen collection, semen collected by this technique contains urine contamination. Besides, volume of semen sample obtained by transrectal massage is lesser compared to electroejaculation. Electroejaculation is also suitable for wild animal because in this particular semen collection procedure, males are not required to be trained.The information about semen characteristics of banteng bulls collected by electroejaculation is less known. To date, study done by Johnston et al. (2002) is the only available data. That study only provided data from one semen sample from one 4-year-old banteng bull located at Western Plains Zoo [2]. Moreover such volume parameter and consistency was not reported from that study. Thus, this study is aimed to provide more reliable data from larger number of semen samples  collected by electroejaculation and to add information to previous data that are availabe.

Abstract

Demand and consumpsion of beef meat increases every year in Indonesia. The increase of  demand is not followed by the availability supply of beef cattle production nationaly. Statistical data from Direktorat Jenderal Peternakan Indonesia  showed that on the year of 2016 the demand of beef was 604.968 ton and the production of beef was only 354.770 ton. The goverment imported of beef and cattle to fulfill the lack of supply, as of 2016 there was  116.761 ton beef and 1.298.560 cattle imported to Indonesia(1).Indonesia has determined to achieve beef self–sufficiency by 2024. To achieve that goal the goverment want to increase the cattle population nationaly by requiring the cattle and buffalo farm industry to oblige the breeding programe. The goverment made some policy including Upsus SIWAB and an obligation of the feedloters of imported cattle to do breeding. According to PERMENTAN no 49 thn 2016 and it’s add on PERMENTAN no 2 thn 2017, importation of beef cattle must meet the ratio 1:5 between breeding cattle and feeder cattle.Reproductive efficiency is a parameter used to determine the success of breeding programe. Reproductive eficiency is a measure of the ability if a cow to become pregnant and produce offspring(2). Optimalization of reproductive efficiency can be one of means to increase national cattle population.Brahman Cross is one of the most common imported cattle breed to Indonesia. Husbandry and reproductive management play an important role to achieve the best result on cattle breeding programe. Feedloters who conduct breeding programe of Brahman Cross cattle (Breedlot) have the capacity and potential to increase the reproductive efficiency of their breeding programe due to they have capital and good management. Thus it is important to assess and measure the reproductive efficiency of Brahman Cross cattle artificially inseminated with frozen semen to increase the reproductive efficiency of beef cattle in the Breedlot.
