Abstract

Abstract. Yendraliza, Rodiallah M, Zumarni, Elfawati, Hidayati, Kusnadi. 2021. Reproduction performance, morphometric and structure population of Kuntu buffalo (Bubalis bubalis Merr) in Kampar District, Riau, Indonesia. Biodiversitas 22: 3370-3377. Kuntu buffalo is one of the germplasm of Riau Province. This study aimed was to determine reproduction performance, potential output, population dynamics, and morphometrics of Kuntu buffalo in Kampar Kiri, Indonesia. The research was conducted in July-October 2019 with materials used in the study were 2.746 buffalo and 1.117 buffalo breeders. The research method used was a survey. The respondents from five locations were determined using a purposive sampling technique. The age at first mating of buffalo 42 ± 0.7 months, the S/C 2.6 ± 1.5 times, calving interval 15.3 ± 2.3 months and calving rate 55.59%. The reproductive efficiency of Kuntu buffalo 96.22%, a natural increase of 55.59%, the net replacements rates (male and female) were 289.60% and 446.59%, respectively and potential output of 39.24% was obtained. The population dynamics of the Kuntu buffalo from 2014 to 2019 experienced a growth of 48% with prediction of the population in 2023 is 7.277 heads. The average body size of male and female Kuntu buffalo is small. The conclusion of Kuntu buffalo reproduction is still efficient with the availability of substitute livestock exceeding the need of livestock and the natural increase of Kuntu buffalo population is very high.

Performa Reproduksi dan Body Condition Score Kerbau Rawa (Bubalus bubalis) Betina di Pulau Lanting

“…Efisiensi reproduksi kerbau pada Desa Pulau Lanting terbilang rendah yaitu sebesar 70,22%, berbeda dengan kerbau yang terdapat pada Kampar, Riau yang memiliki efisiensi reproduksi yang lebih tinggi yaitu 96,22% [19]. Rendahnya nilai efisiensi reproduksi pada Desa Pulau Lanting salah satunya disebabkan oleh terlambatnya umur kawin pertama yang kemudian akan berdampak terhadap sifat-sifat reproduksi lainya, hal ini kemudian akan menyebabkan rendahnya nilai paritas meskipun kerbau telah berumur hingga 84 bulan.…”

Kinerja Reproduksi Ternak Kerbau (Bubalus bubalis) pada Usaha Peternakan Rakyat di Kabupaten Klaten Provinsi Jawa Tengah

“…Indonesia dapat dipengaruhi oleh beberapa faktor, yaitu manajemen pemeliharaan yang masih tradisional, berternak kerbau merupakan usaha sampingan, kekurangan pakan di musim kemarau, dan berkurangnya lahan penggembalaan (Warriach et al, 2015), serta keragaman reproduksi yang masih rendah. Kinerja reproduksi kerbau di beberapa daerah di Indonesia sudah pernah dilaporkan, seperti kerbau Kuntu di Kampar, Riau, yang dilaporkan oleh Yendraliza et al (2021). Kerbau Kuntu memiliki umur pertama kali dikawinkan yaitu 2,5 tahun, umur pertama melahirkan 54 bulan, lama kebuntingan 10,5 bulan dan jarak beranak 15,3 bulan.…”

Effectiveness equilibration time on the quality of sperm buffalo in diluent tris yolk eggs with 4 % extract skin mangosteen (Garcinia mangostana L.)

“…The buffalo population shows a declining trend from 2017 (34,542 heads) to 2019 (23,677 heads) [1]. Shortage of males in the field is the cause of the decline in the population of buffalo [2]. Insemination artificial is one of the anticipations to overcome the shortage of males.…”
