  The main objective of this research is to investigate the potential of LABs isolated from processing byproduct of the VCO in in vitro conditions for use as probiotics in poultry. Forty eight LABs were isolated and four of them have been selected for further study i.e. Lh1, Lh2, Lh3 and Lh4. A series of tests carried out by studying the ability of bacteria to survive at 37 and 42oC, tolerance of LAB at pH 2, 0, 5, 7 and 7, 0 and tolerance to gastric juice as well as sensitivity to several antibiotics commonly was given to poultry. The survival of LABs was evaluated after 15, 30, 60, 90 and 120 and 300 min of incubation. The sensitivity test to antibiotics was performed by Muller Hinton′s agar. All the bacteria showed tolerance and ability to grow at pH 5 and 7, but only Lh4 enabled to tolerate at pH 2. All of LAB can grow at gastric juice stimulated. Lh4 was not sensitive to all antibiotics (clear zones: 0.33 mm) but the other LABs were sensitive (clear zones: 5-12 mm). The conclusion of this research is the ability of LABs to grow in in vitro conditions varies. The Lh4 has demonstrated its ability to grow and the best survival with the OD (λ = 580) is 1.99 after 300 min of incubation at pH 2 and has shown the most resistant to all antibiotics tested with a wide clear zone 0.33 mm, hence potentially be used for probiotic in poultry.

  Kokok Balenggek chicken is a poultry genetic resource from West Sumatera Province, Indonesia, well-known as song fowl for Minang Kabau tribes. This study was conducted in “Agutalok” Captive Breeding Farm in Solok Regency, West Sumatera Indonesia to characterize local chickens based on qualitative traits. This research was aimed to collect basic data of qualitative marker on Kokok Balenggek song fowl. Twenty one adult male of Kokok Balenggek chickens were sampled for this study. Traits studied were number of crow, feather morphology, plumage colour, skin colour, shank colour, comb type, comb colour, earlobes and wattles. The results showed that the number of crows was ranging 5-11 crows. The qualitative traits on Kokok Balenggek chicken were Taduang (4.76%), Jalak (9.52%), Kinantan (9.52%), Kinangkeh (9.52%), Sipatuang rimbo (4.76%), Kuriak padi masak (4.76%), Biriang kalek (23.81 %), Biriang pucek (14.29%), Biriang kuniang (19.05%). Overall, normal feather cover was the main plumage characteristics of Kokok Balenggek chicken populations in the study area. Yellow shanks were dominantly most frequent, followed by black shanks. All chickens studied had earlobes and had wattles. Further studies involving morphometric, production and molecular analyses are important for exhaustive characterization.

  This study was conducted to evaluate the effects of altitude and dietary protein level on performance of local ducks. Two hundred and forty of female Pitalah ducks 14 weeks old were used in this study. Ducks reared on high altitude (H) and low altitude (L). The research was carried out by using Split-plot arrangement in a Randomized Block Design with the H and L as main-plot and the dietary protein level (PL: T-1 = 14, T-2 = 16, T-3 = 18% protein) as sub-plot. Treatments were done when duck was 16 weeks old. Observations were made after the production of duck was 10 %. The environment and rectal temperature were recorded daily. Variables such as: feed intake, protein intake, egg production (Duck day and Egg mass) and Feed Conversion Ratio (FCR) were observed weekly. The altitude were highly significantly (P<0.01) influenced on feed intake, protein intake, egg production (Duck day and Egg mass) and Feed Conversion Ratio (FCR). PL were not significant (P>0.05) affect to feed intake but significantly (P<0.05) increased duck day production and highly significant (P<0.01) increased egg mass and FCR. There was no interaction (P>0.05) between altitude and dietary of protein level. The results of this study showed that the performance of the duck raised on the H was better than L. The increasing of protein level up to 18% have been given the best performance of Pitalah duck.
