ABSTRAKTujuan penelitian ini adalah untuk mengetahui bobot badan dan karakteristik morfometrik beberapa galur ayam lokal. Materi penelitian ini adalah ayam kampung super, ayam kampung unggul balitnak (KUB), dan ayam kampung masing-masing sebanyak 82 ekor. Data yang dihimpun adalah bobot badan, panjang paruh, lebar paruh, panjang kepala, lingkar kepala, tinggi kepala, panjang leher, lingkar leher, panjang sayap, panjang punggung, tinggi punggung, panjang dada, lebar dada, panjang shank, lingkar shank, panjang tibia, lingkar tibia, panjang jari ketiga dan jarak antara tulang pubis. Data bobot badan dan ukuran-ukuran tubuh dianalisis menggunakan uji-t  sedangkan vektor nilai rata-rata ukuran-ukuran tubuh dianalisis dengan menggunakan uji T2-Hotelling. Analisis komponen utama digunakan untuk mengidentifikasi penciri ukuran  dan bentuk tubuh ayam lokal.  Hasil penelitian menunjukkan bobot bahwa bobot badan ayam kampung Super (837,98±68,97 g) berbeda nyata dengan ayam KUB (713,15±66,75 g) dan ayam kampung (605,53±80,01 g). Secara umum ayam kampung super memiliki morfometrik yang relatif lebih tinggi daripada ayam KUB dan ayam kampung. Penciri ukuran tubuh ayam kampung super dan ayam KUB adalah panjang tibia, sedangkan ayam kampung adalah lebar dada. Penciri bentuk tubuh ayam kampung super adalah lebar dada, sedangkan ayam KUB dan ayam kampung adalah panjang punggung. Disimpulkan bahwa bobot badan dan morfometrik tertinggi ditemukan pada ayam kampung super, disusul ayam KUB dan ayam kampung. Ayam kampung Super dan ayam KUB memiliki penciri ukuran tubuh (panjang tibia) yang berbeda dengan ayam kampung (lebar dada). Ayam kampung super memiliki penciri bentuk tubuh (lebar dada) yang berbeda dengan ayam KUB dan ayam kampung (panjang punggung).Kata Kunci: ayam lokal, bobot badan, karakteristk morfometrikABSTRACTThis study aims to determine the bodyweight and morphometric characteristics of several local chicken strains. The research material were three strains of native chicken: kampong super chicken, kampung unggul balitnak (KUB) chicken, and kampung chicken, each strains consisted of 82 heads. Data collection on body weight and morphometric characteristics were performed at 2 months of age. Data collected includes: body weight and morphometric characteristics which include beak length, beak width, head length, head circumference, head height, neck length, neck circumference, wing length, back length, back height, chest length, chest width, shank length, shank circumference, tibia length, tibia circumference, third finger length and pubic bone distance. Data collected were analyzed using t-test to determine differences in body weight and body measurements between chicken strains. Average value vector of chicken body measurements was analyzed using T2-Hotelling statistical test. Principal component analysis statistical test was used to identify the shape and size characteristics of each chicken strain. Data processing was assisted by using Minitab statistical software version 18. Results of this study showed that kampong super chicken has best bodyweight and body weight gain among other strains. The identifier of body size and shape of kampong super chicken were tibia length and breast width. The identifier of body size and shape of KUB chicken were tibia length and back length, while the identifier of body size and shape of the kampung chicken were chest width and back length. Keywords: body weight, native chicken, morphometric characteristic

This study aimed to find out Bali calf performance hybrid with some of the males in Batanghari District Jambi Province.

Tujuan penelitian ini untuk mengetahui Bobot Badan, Pertambahan Bobot Badan Harian dan karakteristik morfometrik sapi Brahman cross dan sapi Bali di Kecamatan Pamenang Barat Kabupaten Merangin. Metode penelitian adalah survey dengan teknik pengambilan sampel secara purpossive sampling, Kriteria sampel umur I1 (16-19 bulan) dan hewan tidak sedang bunting sebanyak 120 ekor yang terdiri dari 60 ekor sapi Bali dan 60 ekor sapi Brahman cross. Data yang dihimpun adalah karakteristik morfometrik meliputi; bobot badan (BB), pertambahan bobot badan harian (PBBH), panjang badan (PB), lingkar dada (LiD), dalam dada (DaD), lebar dada (LeD), tinggi pundak (TP), tinggi pinggul (TPi), dan lingkar kanon (LK). Data yang diperoleh dianalisis menggunakan uji t dan T2-hotelling untuk membandingkan morfometrik antar kelompok bangsa dan bila hasilnya signifikan dilanjutkan dengan Analisis Komponen Utama (AKU) untuk menentukan penciri ukuran dan bentuk sapi Bali dan sapi Brahman cross. Hasil penelitian menunjukan BB, PBB dan ukuran-ukuran tubuh sapi Brahman cross dan sapi Bali berbeda nyata (P<0,05). Faktor penentu ukuran tubuh sapi Brahman cross dan sapi Bali adalah LiD dan faktor penentu bentuk tubuh adalah PB.

The purpose of this research was to determine the body weight, weight gain and morphometric characteristics of several local chicken strains. The research materials were KUB chicken, Sentul chicken, and Arab chicken. The method used was an experiment with a sample of 82 chickens from each strain. Data collected include body weight, weight gain, beak length, beak width, head length, head circumference, head height, neck length, neck circumference, wing length, back length, back height, chest length, chest width, shank length, shank circumference, tibia length, tibia circumference, third finger length, and pubic bone distance. Data collected were analyzed using the average difference test (t-test). The average value vector of body measurements of chicken lines was analyzed using the T²-Hotelling statistical test. Main Component Analysis statistical test was used to identify the shape and size characteristics of each chicken strain. The results showed that the body weight and morphometrics of KUB chickens at 3 months were significantly different (P<0.05) with Sentul chickens and Arab chickens. KUB chicken`s body weight gain at 3 months was not significantly different (P>0.05) from Sentul chickens, but it was significantly different (P<0.05) from Arab chickens. Body weight, weight gain, and morphometrics of KUB chickens were higher than Sentul chickens and Arab chickens. The size indicator in KUB chickens was the tibia length while in Sentul chickens and Arab chickens was chest length. The characteristic of KUB chickens was the back length, Sentul chickens was tibia length, and Arab chickens was the shank circumference.

<p class="MDPI17abstract"><strong>Objective: </strong>Native chickens (Kampung, Sentul, and Merawang) have great potential to be developed as both meat and egg producers. Quantitative data about native chickens are not widely known. The purpose of this research was to determine the quantitative characteristics of Native Chickens aged 1 month, 2 months, 3 months and 4 months.</p><p class="MDPI17abstract"><strong>Methods: </strong>The research material is native chickens. The method used was an 82 sample in each strain and a total of 246 samples. The data collected is of a quantitative traits. Quantitative traits are traits that are influenced by multiple gene pairs, can be measured, and are heavily influenced by environmental factors. Data collected were analyzed using the average difference test (t-test). The average value vector of body measurements of chicken lines was analyzed using the T2-Hotelling statistical test. Main Component Analysis statistical test to identify the shape and size characteristics of each chicken strain.

Bali cattle (Bos javanicus) is an important livestock for the farmers at Jambi Province of Indonesia for meat production purposes. This research was aimed to classify adult Bali cattle (about 3.5 years age) based on their body measurements (morphometrics). The animals in this study were collected from two different altitude areas (lowland and midland) of Jambi province. A canonical discriminant analysis (CDA) was computed in this study for discrimination of animals. A total of 480 animals collected from lowland (180 animals) and midland (300 animals) areas were used in the present study. Thus, seven (7) morphometrical measurements of body length (BL), withers height (WH), chest girth (CG), chest depth (CD), shoulder width (SW), canon circumference (CC) and rump height (RH) were measured in each animal. Research showed that four (4) body measurements, viz. BL, CG, SW and RH were described as the discriminating variables with a canonical correlation of 0.83 (very high). In conclusion, about 90% of Bali cattle at lowland and midland areas could be classified using body measurements.
