(Estimation of genetic parameters of body weight and body measurement of Madura cattle at 205 days) ABSTRAK. This research purposes to analyze the heritability value, genetic correlation, breeding value and rank correlation of breeding value based on body weight and body measurement at 205 days old of Madura cattle in UPT Pamekasan Cattle Breeding and Animal Health. The material used consisted of production records of Madura cattle born from 2014 to 2020. The number of Madura cattle used was 96 heads (46 males and 50 females) from 18 bulls. Data on weaning weight were corrected to 205 days of age. Heritability values were calculated using analyses of variance with paternal half sib correlation model. The results showed that the heritability values of 205 days old were included in the medium category for shoulder height (0.40±0.44), chest girth (0.38±0.43), body weight (0.29±0.39), and the high category for body length (0.82±0.62). The genetic correlation values of body weight with shoulder height, body length, and chest girth were 0.17, 0.08, and 0.017. The highest breeding value for body weight, shoulder height, and body length of Madura cattle aged of 205 days was found in Adikara bull with consecutive values of 2.53, 0.92, 3.98, while the highest breeding value for chest girth was found in 684 bull with a value of 3.25. The conclusion in this study is that the bulls of Madura cattle who have positive values in all variables observed at the UPT Breeding and Animal Health of the East Java Province are the bulls of Adikara and 934. So these bulls can be used as superior bulls to improve the genetic quality of Madura cattle.

Penelitian bertujuan untuk seleksi calon pejantan dan induk sapi Madura berdasarkan nilai pemuliaan berat lahir dan sapih di UPT Pembibitan Ternak dan Kesehatan Hewan Sapi Madura Pemekasan. Materi yang digunakan terdiri dari catatan produksi dan populasi sapi Madura tahun 2016 sampai 2019. Jumlah sapi Madura yang digunakan untuk mengestimasi nilai pemuliaan berat lahir dan sapih adalah 61 ekor (18 ekor calon pejantan dan 43 ekor calon induk) yang selanjutnya dilakukan koreksi untuk estimasi heritabilitas berdasarkan saudara tiri (paternal half sib correlation). Hasil penelitian menunjukkan nilai heritabilitas berat lahir dan berat sapih pada sapi Madura masing-masing adalah 0,41±0,37 dan 00,53±0,45. Rangking nilai pemuliaan calon pejantan sapi Madura berdasarkan berat lahir dan sapih tertinggi diperoleh pejantan no 20/911 (NP: 1,90 kg) dan 30/927 (NP: 16,06 kg) sedangkan pada calon induk diduduki oleh ternak no 10/680 (NP: 2,28 kg) dan 20/395 (NP: 16,48 kg).

Madura, a local cattle breed in Indonesia, is included as a national genetic resource. Genetic evaluation for growth traits in Madura cattle is important for appropriate utilization and improvement of this breed. The aim of this study was to estimate the heritability for growth traits in Madura cattle. The method used in this study is a data recording from 2010 until 2016 including birth weight (190 animals), weight at day 205 (155 animals) and weight at day 365 (135 animals) were used for heritability estimates by using paternal half sib correlation. The results showed that heritability estimates for birth weight, weight at day 205 and weight at day 365 were 0.38±0.17; 0.64±0.22 dan 0.54±0.18. Estimates of heritability for growth traits in Madura cattle ranged between medium and high. In conclusion,growth traits can be used as selection criteria for future genetic improvement in Madura cattle.

This study was aimed to evaluate the effect of complete rations containing soybean pod and soybean by-products (soybean meal and tofu waste) on rumen microbial population, fermentation characteristics, nutrient digestibility, and nitrogen retention of Madura cattle. Twelve Madura cattle of 1.5 years of age were given 4 feeding treatments in triplicates in randomized block design experiment. The treatments included T0 (100% native grass) as a negative control, T1 (concentrate: grass (60:40) as a positive control, T2 (complete ration containing 15% soybean pods), and T3 (complete ration containing 30% soybean pods). The treatments were based on feeding practices commonly applied by farmers in the village. The results showed that the use of concentrate rations or complete rations containing soybean pod and by-product did not affect protozoa population, ammonia concentration, and total VFA production compared to cattle fed 100% native grass. In contrast, the use of concentrate rations or complete rations containing soybean pod and by-products reduced acetate and increased butyrate proportion compared to native grass. The use of a concentrate ration resulted the highest propionate proportion. Methane estimation increased with the use of concentrate ration or complete ration containing 15% soybean pod, but it decreased when the level of soybean pod was increased to 30%. It can be concluded that soybean pod has a potential to be used as a fiber source in beef cattle ration to substitute native grass. [ABSTRACT FROM AUTHOR]

This study was aimed to evaluate the effect of dietary energy level on daily gain of Madura cattle and their blood metabolites (glucose and blood urea). Twelve (12) male Madura cattle aged at 2 years old, 156.27±6.92 kg (CV 4.43%) of body weight were used in this study which was assigned to completely randomized design for three feeding treatments (low, middle and high energy contents) and four replications. The daily gain was measured for 90 days, while the blood metabolites were measured at the middle of experiment. Results showed that dietary energy levels did not affect (P>0.05) average daily gain, dry matter intake, dry matter digestibility, energy intake and feed conversion ratio. Blood glucose and blood urea concentration were ranged at 67-75 and 35-50 mg/dL, respectively, while feed energy efficiency reached 0.145 MJ/g ADG. In conclusion, high-level energy could not provide better performance in Madura cattle because of a limitation factor on the DMI. [ABSTRACT FROM AUTHOR]
