Potency of local feed ingredients and ability of livestock to use the feed: An study.

Objective: The study obtained data on the potential of local feed ingredients, both in quantity, quality, and continuity and to observe the absorption power and ability of livestock to use feed designed .

Materials And Methods: The method uses a survey method of potential sources of animal feed and calculates the carrying capacity of ruminants and nutritional analysis of feed ingredients with proximate analysis. Feed formulations were made based on proximate analysis results of four formulas (P, P, P, and P) and tested .

Genetic features of red and green junglefowls and relationship with Indonesian native chickens Sumatera and Kedu Hitam.

Background: More than 2,500 breeds of chicken are reared throughout the world as a source of eggs or meat and as pets. The primary ancestor of the present domestic chicken is widely believed to be the red junglefowl, although genetic contributions from other junglefowls cannot be excluded entirely. The reference genome for chicken was obtained from a red junglefowl, the genetic purity of which has been debated.

Evidence of Bos javanicus x Bos indicus hybridization and major QTLs for birth weight in Indonesian Peranakan Ongole cattle.

Background: Peranakan Ongole (PO) is a major Indonesian Bos indicus breed that derives from animals imported from India in the late 19(th) century. Early imports were followed by hybridization with the Bos javanicus subspecies of cattle. Here, we used genomic data to partition the ancestry components of PO cattle and map loci implicated in birth weight.
