Abstract: Balai Pembibitan Ternak Unggul – Hijauan Pakan Ternak (BPTU-HPT) Siborongborong is one of breeding
station in Indonesia. One of animal which has been maintained is Murrah buffalo. The aims of the research
are to calculated inbreeding coefficient and inbreeding rate of Murrah buffalo. Data and pedigree
information were collected from 17 buffalo’s (7 males; 10 females) in 2017 and 14 buffalo’s (6 males ; 8
females) in 2018. The inbreeding coefficient was calculated using of pedigree analysis and inbreeding rate
per generation based on the population structure. The result of inbreeding coefficient was 0,219 while the
inbreeding rate was 2,29%. Significant inbreeding depression was found in BPTU-HPT Siborongborong
because the breeding station wasn’t regularly optimum rotated bull/generation.
1 INTRODUCTION
Balai Pembibitan Ternak Unggul-Hijauan Pakan
Ternak Siborongborong has a main duty to
maintenance, breeding, development, production and
distribution of superior livestock and production and
distribution of forage seeds. Some of its functions
include 1) maintenance and production of superior
livestock seeds, 2) implementation of performance
test and superior livestock zuriat test, 3)
implementation of superior livestock breeding, 4)
implementation of germplasm conservation and 5)
implementation of superior livestock breeding. In
carrying out the main tasks and functions of the
station, the implementation of activities is supported
by several installations such as Siaro installation,
Silangit, Bahal Batu and Rodaman Palas. Installation
Siaro is a pig development site with an area of 17.5
Ha. Installation of Silangit is a place for the
development of riverian buffalo (Murrah Buffalo)
with an area of 23 Ha. Installation of Bahal Batu and
Rodaman Palas where the development of swamp
buffaloes with an area of 59.5 Ha and 94 Ha.
The Silangit Installation is one of the existing
installations under the Siborongborong BPTU-HPT
that carry out their main tasks and specific functions
for the maintenance, production, breeding and
development of Murrah buffalo. Murrah buffalo was
brought to this location first time in 1994 about 25
heads from the Murrah buffalo breeder in Deli
Serdang district. Since 1994 until now, Silangit
installation has been maintaining, producing and
breeding Murrah buffalo. The current population of
Murrah buffaloes in Silangit installations is 81 heads
consisting of 2 males, 18 females, 4 adult males, 16
adult females, 2 young males, 5 young females, 12
calves male and 22 calves females. Murrah buffalo
is maintenanced with a system where in the morning
grazed and in the afternoon put into the cage. Feed is
given in the form of forage and concentrate. Patterns
of mating with natural and artificial mating systems
(artificial insemination). Natural mating is done by
utilizing the stud in the installation. While the
artificial mating is done by using the straw from
UPTD BBID North Sumatra. Where the bull in
UPTD BBID North Sumatra is coming from the
murrah buffalo breeder in Deli Serdang District.
Since the Murrah buffalo was introduced to the
BPTU-HPT Siborongborong, there has been no
observation and calculation of inbreeding.
Inbreeding may occur due to the origin of buffaloes
in BPTU-HPT Siborongborong and UPTD BBID
North Sumatera are originated from one population
in Deli Serdang District. The origin of the same
