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 2019were used for determining NIandNRR, and it isusedfor estimation of output. Population 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 population 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.

The method of data collection was done by interviewing farmers directly (respondents) using questionnaires. There were 4 subdistricts those were being the targets of the population, namely from 13 subdistricts in Pamekasan District were the locations for maintaining sonok cattle. Cluster proporsive sampling was determined by the sample of respondents, that was the method of sampling by setting characteristics those were in accordance with the objectives and criteria, namely all of the Sonok cattle those were kept by farmers in 4 subdistricts in Pamekasan District which were the centers for Sonok cattle breeding. The reproduction status of Sonok cattle in Pamekasan District was quite good. The first age of marriage was 23.40 ± 4.17, S / C 1.59 ± 0.53 times, the distance between young calf 14.50 ± 1.83 months, and the value of reproductive efficiency (ER) is 90.51%. The natural increase (NI) value of Sonok cattle in Pamekasan District in 2014 was 9.55%, the value of net replacement rate (NRR) was 101, 48%. The estimation result of Sonok cattle output was 8.24%. Madura cattle population dynamics at the Sonok cattle Nursery Center in Pamekasan District in the period of 2013 to 2017 experienced an average increase of 7.98% annually. The estimated results of the population dynamics from 2018 to 2022 were expected to increase annually by 9.18%. It was concluded that Sonok cattle in Pamekasan District still had the potential to increase the population and the output value was lower than NI (5.06% vs. 15.81%). Keywords : Pamekasan District, Reproduction Status, Natural Increase Value, Sonok Cattle, Questionnaire

AbstractA disrupted allele (r1) of a cadherin gene (Ha_BtR) is genetically associated with incompletely recessive resistance toBacillus thuringiensistoxin Cry1Ac in a Cry1Ac-selected strain (GYBT) ofHelicoverpa armigera. Ther1allele ofHa_BtRwas introgressed into a susceptible SCD strain by crossing the GYBT strain to the SCD strain, followed by repeated backcrossing to the SCD strain and molecular marker assisted family selection. The introgressed strain (designated as SCD-r1, carrying homozygousr1allele) obtained 438-fold resistance to Cry1Ac, >41-fold resistance to Cry1Aa and 31-fold resistance Cry1Ab compared with the SCD strain; however, there was no significant difference in susceptibility to Cry2Aa between the integrated and parent strains. It confirms that the loss of function mutation ofHa_BtRalone can confer medium to high levels of resistance to the three Cry1A toxins inH. armigera. Reciprocal crosses between the SCD and SCD-r1 strains showed that resistance to Cry1Ac in the SCD-r1 strain was completely recessive. Life tables of the SCD and SCD-r1 strains on artificial diet in the laboratory were constructed, and results showed that the net replacement rate (R0) did not differ between the strains. The toxicity of two chemical insecticides, fenvalerate and monocrotophos, against the SCD-r1 strain was not significantly different from that to the SCD strain. However, larval development time of the SCD-r1 strain was significantly longer than that of the SCD strain, indicating a fitness cost of slower larval growth is associated withHa_BtRdisruption inH. armigera.

Said S, Putra WPB, Anwar S, Agung PP, Yuhani H. 2017. Phenotypic, morphometric characterization and population structure of Pasundan cattle at West Java, Indonesia. Biodiversitas 18: 1638-1645. Identification of phenotypic and morphometric characteristics in indigenous cattle is important in characterizing breeds of animals. This study was carried out to identify the phenotypic and morphometric characteristics of 813 indigenous Pasundan cattle from West Java Province of Indonesia. The coat color of Pasundan cattle is mainly solid reddish brown (>90%) with black color on hoof (>90%), switch of tail (>80%), eyelid (>90%), muzzle (>90%), horn (>90%) and whitish color on mouth lash (>80%) and reddish brown color on legs (>60%) and rump patch (>60%). The physical characteristic of Pasundan cattle mainly is the hump in males (65.23%) or humpless in female (74.91%), small dewlap size (>60%), presence of back line (>60%) and horned (>80%) with upper curved horn (>90%). The average of withers height (WH), body length (BL), chest girth (CG) and scrotal circumference (SC) of adult male Pasundan cattle were 128.94+16.69 cm; 128.72+15.98 cm; 159.36+15.84 cm and 17.68+3.51cm respectively. Therefore, the average of WH, BL, and CG of adult female Pasundan cattle was 122.56+11.40 cm; 115.63+19.06 cm and 140.13+12.16 cm respectively. Natural Increase (NI) and calf crop values were 18.46% (low category) and 20.40% respectively. Net Replacement Rate (NRR) values were 300% (male) and 507% (female) and indicated that West Java province was still capable to produce seed stock per year.
