Abstract

The existence of selection on the rabbits with potential for meat has only been seen from phenotypic aspects including performance and productivity, while the molecular genetic studies are still very rare. One of the candidate genes for meat production traits in rabbit is myostatin. Totally 50 blood samples of male rabbits from Rex, Satin, Reza (crossing from Rex and Satin), Flemish Giant and FZ3 (crossing from Flemish Giant and Reza) breed were used at Indonesian Research Institute for Animal Production (IRIAP). Genetic polymorphism by Polymerase Chain Reaction – Restriction Fragment Length Polymorphism (PCR-RFLP) method used FspBI restriction enzyme. PCR-RFLP data were analyzed by calculating allele and genotype frequencies. Sequencing was performed in rabbit with different genotypes which represents each of the samples. Genotype of AT had two cut points of the FspBI restriction enzyme at the base position of 508 bp and 444 bp. The cut point at the base position of 446 bp was site mutation base T became A. Genotype of TT had one cut point at the base position of 508 bp and no mutation site. Allele T had higher frequency than allele A and just Rex and Reza rabbit breeds had two alleles. The other rabbits (Satin, Flemish Giant and FZ3) only had one allele i.e., allele T. PCR - RFLP analysis of the MSTN|FspBI gene segments was polymorphic in Rex and Reza rabbit breeds. All of rabbit breeds in this study did not have AA genotype.Key words: myostatin gene, rabbit

Abstract

Kelinci berpotensi sebagai alternatif sumber protein hewani. Daging kelinci mengandung protein tinggi dan kandungan lemak yang rendah dibandingkan dengan daging ternak lain. Saat ini, informasi terkait performa karkas kelinci Rex dan lokal masih sangat kurang. Penelitian ini bertujuan untuk mangetahui performa karkas, perlakuan fisik dan kimia pada daging kelinci Rex dan lokal. Analisis statistik yang digunakan pada penelitian ini adalah Rancangan Faktorial 2x2 dengan 3 kali ulangan. Faktor pertama adalah jenis kelinci dan faktor kedua adalah jenis kelamin. 6 ekor kelinci Rex dan kelinci lokal yang digunakan pada penelitian ini adalah 3 jantan dan 3 betina. Hasil penelitian menunjukkan bahwa kelembaban daging kelinci Rex lebih tinggi dibandingkan dengan kelinci lokal (P<0,05). Kelinci betina memiliki nilai pH, keempukan dan daya ikat air yang lebih baik dibanding kelinci jantan (P<0,05). Perbedaan antar perlakuan dipengaruhi oleh manajemen pemeliharaan, perlakuan sebelum antemortem dan postmortem, dan juga aktivitas kelinci.

Abstract

Food diversification need to use other kind livestock which have high biological potency, economic, halal, good nutrition as meat-animal including rabbit. Rex have a medium body size compared with other kinds of frayer. The aim of this research was to determine Rex carcass and non carcass productivity. The research was used completely randomized design with four treatments. Statistical analysis used in this research was Analysisof Covariance Design (ANCOVA). Rex males were used as sample. Rex’s growth, carcass and non carcass productivity were observed. The result showed that slaughter ages had an effect on slaughter weight, carcass weight, meat weight and percentage of meat and bone. The growth of non carcass components such as heads, feets, skins and digestive tracts were affected by slaughter ages. 12 weeks-old Rex produced highest meat percentages from body weight. It was obtained that 12 weeks-old Rex produced optimal growth, slaughter weight and carcass productivity.

Abstract

Rabbits are meat-producing livestock with high productivity. Rabbit meat has high nutritional content and is good for health. The DKI Jakarta Government through the Center for Animal Health and Livestock Services (Pusyankeswannak) has opened the Bambu Apus Livestock Park. This research was conducted to determine the productivity of bambu apus rabbit carcasses as broiler rabbits to support urban farming programs in DKI Jakarta. Ten of bambu apus rabbits (five males and five females), ten of new zealand white rabbits (eight males and two females) and 17 rexsi grinak rabbits (eight males and nine females) were used. The body weights of the rabbits ranged from 2000 to 3000 g per head. This research has obtained Ethical Clearance (Balitbangtan/Center for Animal Husbandry Research BRIN/NRm/01/2022). Rabbits were slaughtered according to Islamic Syar’i and the carcass were cutting according to the commercial cut. A completely randomized design with a 3 x 2 factorial pattern (sex and type of rabbit) was used with carcass productivity and meat physical properties as variables. Bambu apus rabbits have good carcass productivity (Carcass Percentage, Meat Bone Ratio), meat on commercial cuts (Loin and Hindleg) and carcass quality (pH, tenderness, Water Holding Capacity and cooking losses) which were the same as new zealand white rabbits and rexsi agrinak rabbits as the broiler rabbit. Bambu apus rabbits have good carcass production and carcass meat quality so they have the potential to be developed into broiler rabbits in support of urban farming programs.
