Protein concentrate from palm kernel meal (BIS PRO) was produced using combination method of grinding and ethanol extraction. The experiment was conducted to evaluate physico-chemical properties and metabolizable energy value of BIS PRO in broiler. The metabolizable energy experiment was conducted in Completely Randomized Design using 19 broilers Ross strain with average body weight of 1.79 ± 0.11 kg. The treatment diets were: R1(90 % basal diet + 10% palm kernel meal), R2 (90% basal diet + 10% BIS PRO) and R3 (90% basal diet + 10% soybean meal).The result showed that BIS PRO had higher specific density (0.723 g/ml), compacted specific density (0.885 g/ml), specific gravity (1.596 g/ml), and angle of repose (28.320) compared to those of palm kernel meal and soybean meal. Total solubility of BIS PRO (70.22%) were higher than that of the others. BIS PRO had metabolizable energy of 1.94 – 2.66 time higher compared to metabolizable energy of palm kernel meal, but there was no difference compared to metabolizable energy of soybean meal. It is concluded that BIS PRO has physicochemical properties and metabolizable value better than that of palm kernel meal and were equal to that of soybean meal.

The experiment was conducted to investigate degradation of dry matter (DM) and protein of mulberry and rice bran when incubated in nylon bag in the rumen at different incubation times and different rumen environments of rumen-cannulated adult sheep. Three different rumen conditions were created by feeding the three rumen-cannulated sheep with urea-treated rice straw as basal diet and offered with three supplemental treatment diets on different source of energy and nitrogen. Mulberry, urea and rice bran were used as source of fermentable energy and protein. Treatments consisted of control diet mulberry and molasses (T0); 50% mulberry was replaced by rice bran and urea (T1); and 100% of mulberry was replaced with rice bran and urea (T2). The diets were formulated in iso protein and iso energy. Supplemental diets were offered at 1.2% BW. The study was conducted in three periods. For each period, the sheep was offered with one of three supplemental treatment diets. The nylon bags each, contains sample of either mulberrry or rice bran were incubated in the rumen of sheep at different incubation times in reverse order (48, 24, 12, 9, 6, and 3h). Degradation characteristic data were obtained by analyzing degradability data with the equation of p = a+b(1-e-ct) using Neway computer package. Data of degradation characteristic, degradability of DM and CP, DMI, rumen NH3-N and pH were subjected to analysis of variance (ANOVA) using a SAS software package. The results showed that the dry matter intake (DMI) and rumen pH were not significantly different between diets. The rumen ammonia concentration of T1 and T2 was significantly higher than that of T0. However, the rumen ammonia concentration was higher than that of critical value for rumen microbial synthesis (>5mg/100ml). The rate (c value) of DM degradability of mulberry and rice bran was affected by diet treaments, where T2 diet resulted in lower c of mulberry and rice bran. Only CP degradability of mulberry on the other hand was affected by diet treatments. But, both CP mulberry and rice bran had high degradability (>80% after 24 hs incubation) in all diet treatments. It is concluded that the three diets of this study were capable of creating the optimum condition for rumen fermentation. Supplementation of mulberry or urea-rice bran mixture had similar effect on protein degradability of rice bran. On the other hand, the rate of protein degradability of mulberry was reduced when it was incubated in the rumen of sheep fed urea rice bran mix supplement.

Wareng and Kampung chicken are Indonesian native chicken that have good potential to be dual purpose chicken. Information on these chickens has not hast’n widely published so that their genetic potential is unknown. The purpose of this research is to collect basic data of the external genetic characteristic from Wareng and Kampung chickens consisting feather color, feather pattern, feather feature, feather shine, shank color and comb shape; to identify rate of introgression imported breed (Rhode Island Red, White Leghorn and Barred Plymouth Rock), the purity and genetic variability of Wareng and Kampung chickens. This study was carried out at the Research Institute for Animal Production, Ciawi, Bogor. Materials used were 361 of Wareng chickens (313 females, 48 males) and 439 of Kampung chickens (352 females, 87 males). Data were analyzed using formulas to identify gene frequency, rate of introgression of purity native gene frequency and the genetic variability. The result showed that the control of gene constitution on external characteristic of Wareng chicken was I_ E_ bb S_ Id_ pp and ii e+ _bb ss idid pp on Kampung chicken. Wareng chicken own constitution of gene the same as with White Leghorn (II EE SS BB IdId pp). Wareng Chicken is not containing frequency of original gene of Indonesian local chicken (Kampung). The level of influence value (rate of introgression) from Europe and American chicken for Wareng chicken was of equal to 84% and 25% to Kampung chicken. So that the purity for Wareng chicken was 16% and 75% was for Kampung chicken. The variability genetic of Kampung chickens (39%) higher than Wareng chicken (16%).

The Mitochondrial DNA (mtDNA) D-loop segment was PCR amplified and subsequently sequenced for a total of 335 individuals from Indonesian native chicken. The individuals were drawn from sixteen populations of native chicken and three individuals of green jungle fowls (Gallus varius). Indonesian native chicken populations were: Pelung Sembawa, PL (n = 18), Pelung Cianjur, PLC (n = 29) and Arab Silver, ARS (n=30), Cemani, CM (n = 32), Gaok, GA (n = 7), Kedu Hitam, KDH (n = 11), Wareng, T & TW (n = 10), Cemani, CMP (n = 2), Kedu, KD (n=26), Kedu Putih, KDP (n = 15), Sentul Jatiwangi, STJ (n = 27), Ayam Kate, KT (n = 29), Ayam Sentul, STC (n = 15), Arab Golden, ARG (n = 26), Ayam Merawang, MR (n = 28), Kedu Putih Jatiwangi, KDPJ (n=6) and Kapas, KPS (n = 21). Green jungle fowls were: two individuals from Flores island (FL5 and FL57) and one individual (BD42) from Sumbawa island. The sequences of the first 530 nucleotides were used for analysis. Eighty two haplotypes were identified from 78 polymorphic sites for the 335 individuals. Seventy nine haplotypes were identified in native chicken from 57 polymorphic sites while three were of jungle fowls. Phylogenetic analysis indicates that Indonesian native chicken can be grouped into five clades (Clade I, II, IIIc, IIId and IV) of the previously identified seven clades (Clade I, II, IIIa, IIIb, IIIc, IIId and IV) in Asian domestic chicken. Haplotypes CM10 and CM32 fall to a different category while STC12 is also on its own. Interestingly STC12 clusters together with Gallus gallus gallus (GenBank accession No. SULANDARI et al. Analysis of genetic relationship among Indonesian native chicken breeds based on 335 D-loop sequences 296 AB007720). When CM10 (same as CM14), CM32 and STC12 were removed, 77 haplotypes of domestic chicken were identified from 53 polymorphic sites. All the green jungle fowls are clustered to one clade of their own. The clades of domestic chicken are: Clade I which has three haplotypes, Clade II has 52 haplotypes, Clade IIIc has one haplotype (represented by ARS30), Clade IIId has nine haplotypes while Clade IV has eleven haplotypes. The phylogenetic relationship between chicken populations has no link to the geographic locations. Analysis of molecular variance showed that the genetic variation within populations was 67.42% while 32.58% accounted for the genetic differentiation between populations.

Bucks semen is easily damaged compared to bull semen during cryopreservation process. Consequently, frozen semen quality decrease especially motility, live sperm, intact plasma membrane, and intact acrosomal cap after thawing. Objectives of this research was to evaluate the effect of egg yolk concentration in Tris extender with and without seminal plasma in maintaing frozen semen quality of Saanen buck. Four heads of Saanen buck of 2-4 years old were used in this experiment. Semen was collected once a week using artificial vagina. Experimental design applied was factorial complete random desing 2x2, viz. A factor was seminal plasma (A1 = with seminal plasma and A2 = without seminal plasma), and B factor was concentration of egg yolk (B1 = 10% and B2 = 20%). Duncan test were applied to identity differences between treatment. Result of these study indicated that the mean percentage of motility (M), live sperm (LS), sperm with intact plasma membrane (IPM) and intact acrosomal cap (IAC) after dilution and equilibration were not significantly different (P>0.05) in all treatment. After thawing, the mean percentage of M, LS sperm with IPM and IAC in A1 treatment (41.43, 51.52, 56.63 and 50.35% respectively) were significantly higher (P<0.05) than A2 treatment (37.14; 48.67; 52.31 and 45.09% respectively). Likewise, the mean percentage of M, LS, sperm with IPM and IAC in B2 treatment (41.79; 51.32; 55.78 and 49.50% respectively) were significantly higher (P<0.05) than B1 treatment (36.79, 48.86; 53.16 and 45.94% respectively). There were a significant interaction between factors of seminal plasma and concentration egg yolk in Tris extender, where the increase of egg yolk concentration from 10% to 20% in unwashed seminal plasma treatment caused increase in percentages of M, LS, sperm with IPM and IAC. On the other hand in washed seminal plasma treatment there were a trend of decreasing frozen semen quality. It is concluded that the combination of 20% egg yolk in Tris extender with seminal plasma is effective in maintaining frozen semen quality of Saanen bucks.
