Abstract

This study aimed to estimate natural increase (NI), net replacement rate (NRR), output, and population dynamics of Aceh cattle at Livestock Breeding and Forage Center in Indrapuri, Aceh province. Data of population structure, mortality, birth rate, the number of animals entering the herd, and the number of animals released from the herd during 2019 were used for determining NI and NRR , and it is used for estimation of output . P opulation structure data (2015-2019) were used to estimate the population dynamics. The results showed that NI was 19.08% (medium category). The availability of replacement stock exceeded the need for replacement (140.08% for male and 73.33% for female); the NRR was 240.08% (male) and 173.33% (female). The output of Aceh cattle was 3.92% (culled male), 5.58% (culled female); the remaining replacement stocks were 5.49% (male) and 4.09% (female) of the total population. The populatio n of Aceh cattle from 2020 to 2024 was expected to increase by 6.02% (65 heads) on average. In conclusion, that BPTU-HPT Indrapuri can be categorized as a beef cattle producing region, but still need efforts to increase natural increase by increasing birth rate minimum 32.77% and reducing mortality maximum 3.0%, in combination with better management systems.

Indrapuri畜牧养殖和饲料中心亚齐牛的自然增长、净替代率、产量和种群动态

本研究旨在估计亚齐省Indrapuri畜牧养殖和饲料中心亚齐牛的自然增长（NI）、净替代率（NRR）、产量和种群动态。2019年期间，种群结构、死亡率、出生率、进入牛群的动物数量和从牛群中释放的动物数量的数据用于确定NI和NRR，并用于估计产量。P种群结构数据（2015-2019）用于估计种群动态。结果表明，NI为19.08%（中等）。替代库存的可用性超过了替代需求（男性为140.08%，女性为73.33%）；NRR分别为240.08%（男性）和173.33%（女性）。亚齐牛的产量为3.92%（扑杀雄牛），5.58%（扑杀雌牛）；其余替换种群分别占总种群的5.49%（雄性）和4.09%（雌性）。从2020年到2024年，亚齐牛的数量预计将平均增加6.02%（65头）。总之，BPTU-HPT Indrapuri可以被归类为肉牛生产区，但仍需要努力通过提高出生率最低32.77%和死亡率最高3.0%来增加自然增长，并结合更好的管理系统。

期刊介绍： Journal of the Indonesian Tropical Animal Agriculture (JITAA) is a double blind peer-reviewed publication devoted to disseminate all information contributing to the understanding and development of animal agriculture in the tropics by publication of original research papers. The journal covers all aspect relating to Animal Agriculture, including: -Animal breeding and genetics -Animal feeding and nutrition -Animal reproduction -Animal biotechnology -Animal physiology -Animal production and technology -Animal products technology -Animal management and economics -Animal products processing and animal by-products -Animal microbiology -Livestock farming systems -Other related topics in relation to animal science. The topics of research are not only on Indonesian tropical animal agriculture, but also on other tropical regions of the world.
