An experiment in feeding pre-starter diets was carried out on local chicken (KUB chicken) raised to the age of 84 days. Four hundred and eighty day-old KUB chicks were allocated to experimental diets of P1 = standard diet without pre-starter; P2 = OASISÂ® pre-starter for 48 hours feeding; P3 = COBA-1, a mixture of 76.3% yolk powder, 0.76% inulin powder, 7.63 % honey and 15.3% tomato sauce, for 24 hours feeding; P4 = P3 given for 48 hours feeding; P5 = fresh papaya for 24 hours feeding; P6 = P5 for 48 hours feeding; P7 = fasting for 24 hours and P8 = fasting for 48 hours. Following treatment, the chicks were then fed with standard diet, containing 17.5 % crude protein with 2800 kcal ME/kg up to the end of the experiment. Results showed that the group of chicken on pre-starter diet of ripe papaya fruit (P5 and P6), responded better EPEF (European Performance Efficiency Factor) value of 442 and 356 g/bird, respectively in chicken of P5 and P6. This better response was due to particularly higher viability and the efficiency in utilization of feed. Key Words: Pre-starter Diets, KUB Chicken, Performance

Observation on carcass and carcass cuts of F1 crossbred of Pelung x Kampung chickens influenced by dietary protein (15%, 17%, 19%, and 21% crude protein=CP) was carried out at the Research Institute for Animal Production, Ciawi Bogor. There were 360-day-old chicks of the crossbred, allocated to 9 dietary-protein treatments. The treatments were P1 (21%-17% CP), which was the ration with 21% CP given to chicks aged of 0-6 weeks, then continued with 17% CP ration up to 12 week of age; P2 was 21%-15% CP; P3 was 19%-19% CP; P4 was 19%-17% CP; P5 was 19%-15% CP; P6 was 17%-17% CP; P7 was 17%- 15% CP; P8 was 15%-19% CP and P9 was 15%-15% CP. At 6 and 12 weeks of age each two out of 10 birds per cage were randomly picked for carcass and carcass portion analysis. Results showed that carcass and wings of 6 weeks of age birds were not significantly (P>0.05) influenced by dietary protein, whilst breast and thighs & drumsticks were significantly (P<0.05) lower on lower dietary protein. The weight of carcass and carcass parts were 256, 58, 71, 32, 44, 8.6, 9.7 and 2.09 g/bird, for carcass, breast, thighs and drumsticks, wings, oval; liver, gizzard and abdominal fat, respectively. At 12 weeks of age, weight of carcass and carcass cuts were not affected by dietary protein. The weight of carcass and carcass cuts of 12 weeks of age were 803, 189, 251, 102, 123, 20, 25 and 21 g/bird, for carcass, breast, thighs and drumsticks, wings, oval, liver, gizzard and abdominal fat, respectively. The results indicated that ration with 15% CP given up to 12 weeks of age was recommended to be optimum without any reduction in carcass quality.

This experiment aimed to determine the effect of phytase enzyme and ZnO supplementation on the percentage of weight of carcass, commercial cuts, abdominal fat of males, and females of Sentul-G3 chicken fed high rice bran diet. There are nine treatments, R1 = 50% commercial diet: 50% rice bran; R2 = R1 + 1.5 g ZnO/kg; R3 = R1 + 3.2 g ZnO/kg; R4 = R1 + phytase 1.000 U/kg; R5 = R1 + (phytase 1.000 U/kg + 1.5 g ZnO/kg); R6 = R1 + (phytase 1.000 U/kg + 3.2 g ZnO / kg); R7 = R1 + phytase 2.000 U/kg; R8 = R1 + (phytase 2.000 U/kg + 1.5 g ZnO/kg); dan R9 = R1 + (phytase 2.000 U/kg + 3.2 g ZnO/kg). Each experimental unit consisted of 6 animals unsexed local chicken Sentul-G3. Beside that, used commercial diet treatment. Parameters observed were percentage of weight of carcass, commercial cuts, abdominal fat of males, and females of Sentul-G3 chicken. The experimental results showed that the diet treatment did not gave effect to percentage of weight of male and female carcass, male and female backs, the female wings, upper thights and abdominal fat of male and female chickens Sentul-G3. Diet treatments gave varies effect to weight percentage of male and female breast, upper thighs female, male and female lower thighs chicken Sentul-G3. The combination of 2.000 U phytase and 3.2 g of ZnO/kg diet lowers weight percentage of male wings. Supplementation of 1.5 g ZnO/kg diet increases abdominal fat deposition.

One hundred unsexed chicks of each group of Kedu x Arab cross, of Arab x Arab and of Kedu x Kedu were kept under intensive husbandry for about 52 days (from 32 to 84 days of age). Each group was allocated to 10 cages of 10 unsexed birds. Experimental rations consisted of main ingredients of ground yellow corn, soybean meal, rice bran and fishmeal. Experimental ration were R1 containing energy of 2920 kkal ME/kg with crude protein of 15.17%. R2a contained energy of 3087 kkal ME/kg with crude protein of 7.36% and R2b contained energy of 2336 kkal ME/kg with crude protein of 42,51%. R1 ration was given ad libitum for 24 hours and R2a ration was given from 08.00 a.m.–12.00 p.m. and continued with R2b ration was given up to 8.00 a.m. in the following day. Results showed that live bodyweight and bodyweight gain were not significantly different among the three groups of chicken. Feed consumption of Kedu x Arab cross was significantly lower than that of Kedu x Kedu nor Arab x Arab. Feed conversion ratio of Kedu x Arab cross was also significantly lower (3.74) than its comparative groups. Birds on R1 ration grew faster (804 g/bird) than that on R2a-R2b ration (738 g/bird) with feed consumption of 2135 g bird-1 52 day-1 on R1 ration versus 2338 g bird-1 52 day-1 on R2a-R2b ration. FCR of the birds were lower on R1 ration (3.44) than on R2a-R2b ration (4.26). Energy consumption, protein consumption, protein efficiency ratio, energy efficiency ratio did not show significant different among the three groups of chicken, but for all those variables under R1 ration were significantly higher than for those under R2a-R2b ration. Whole carcass and carcass cuts were not significantly affected by neither the kind of chickens nor dietary treatments. Development of liver was the slowest among development of other carcass cuts and organs, whilst development of breast meat was 4.4–6.0 times, and drumstick meat was 4.6–6.6 times.

The success of freezing chicken semen is the hope for preserving Indonesian native chickens. Semen from twenty Arab roosters were collected using massage technique once in a week. Cryoprotectant DMA (dimethyl acetamide) or DMF (dimethyl formalmide) of 7 or 9% and thawing A at temperature of 30oC for 30 seconds or in B at 5oC for 5 minutes. The volume of fresh semen was 0.3 ± 0.072 ml/ejaculate, white colour, rather thick to thick, with 2200 ± 372 millions sperms/ml and pH 6.95 ± 0.32, 4+/3+ mass movement, 80% motility, 84 ± 4.48% and abnormality of 14.75 ± 1.28%. There were not statistically significant (P>0.05) effect of interaction of treatments (kinds and concentrations of cryoprotectant, and thawing methods) on motility and live-sperms. Sperm motility preserved with DMA (34.69%) significantly higher than with DMF (29.84%). Sperm motility was also significantly higher (34.53%) when preserved with 7% cryoprotectant than with 9% (30%). Thawing-A significantly gave higher motility (35.31%) than thawing-B did (29.22%). Live-sperms of semen preserved with DMA (46.75%) was significantly higher than with DMF (41.72%). Cryoprotectant concentration of 7% gave higher live-sperms (46.98%) than of 9% did (41.48%). Thawing-A left live-sperms of 47.14%, which was significantly higher than thawing-B did (41.30%).

This study was conducted to determine the effect of phytase enzymes and ZnO supplementation on the performance of native chicken Sentul-G3 fed high rice-bran diet. Two hundred and seventy day old chicks (DOC) native chicken Sentul-G3 from three different hatcheries were used in this study. Factorial randomized block design (3 x 3) was applied in this study. The first factor was the enzyme phytase supplementation levels (0; 1000; 2000 U/kg), the second factor was the level of supplementation of ZnO (0; 1.5; 3.2 g/kg), so that there are nine treatment given, namely R1 = 50% commercial diet : 50% rice bran; R2 = R1 + 1.5 g ZnO/kg; R3 = R1 + 3.2 g ZnO/kg; R4 = R1 + phytase enzyme 1000 U/kg; R5 = R1 + (phytase enzyme 1000 U/kg + 1.5 g ZnO/kg); R6 = R1 + (phytase enzyme 1000 U/kg + 3.2 g ZnO/kg); R7 = R1 + phytase enzyme 2000 U/kg; R8 = R1 + (phytase enzyme 2000 U/kg + 1.5 g ZnO/kg); R9 = R1 + (phytase enzyme 2000 U/kg + 3.2 g ZnO/kg). Each experimental unit consisted of 6 head unsexed native chicken Sentul-G3. The experimental diet was fed for 10 weeks. The variables measured were body weight, body weight gain, feed intake, feed conversion ratio, mortality, mineral deposition of Ca, P, Zn in the tibia bone, alkaline phosfatase enzyme activity in serum. Results showed that there was significant interaction (P<0.05) between phytase enzyme and ZnO supplementation on body weight, body weight gain, feed conversion, zinc deposition in the tibia bone. There was no significant interaction (P> 0.05) between phytase enzyme and ZnO supplementation on feed intake, mortality, alkaline phosphatase enzyme activity in serum, and deposition of calcium and phosphorus in the tibia bone. It was concluded that supplementation of phytase enzyme and ZnO were not able to increase the growth of native chicken Sentul-G3 on fed diet containing high rice bran.

An experiment in feeding pre-starter diets was carried out on local chicken (KUB chicken) raised to the age of 84 days. Four hundred and eighty day-old KUB chicks were allocated to experimental diets of P1 = standard diet without pre-starter; P2 = OASIS® pre-starter for 48 hours feeding; P3 = COBA-1, a mixture of 76.3% yolk powder, 0.76% inulin powder, 7.63 % honey and 15.3% tomato sauce, for 24 hours feeding; P4 = P3 given for 48 hours feeding; P5 = fresh papaya for 24 hours feeding; P6 = P5 for 48 hours feeding; P7 = fasting for 24 hours and P8 = fasting for 48 hours. Following treatment, the chicks were then fed with standard diet, containing 17.5 % crude protein with 2800 kcal ME/kg up to the end of the experiment. Results showed that the group of chicken on pre-starter diet of ripe papaya fruit (P5 and P6), responded better EPEF (European Performance Efficiency Factor) value of 442 and 356 g/bird, respectively in chicken of P5 and P6. This better response was due to particularly higher viability and the efficiency in utilization of feed.

Two lines of native chicken (Kampung and Pelung cross) were subjected to diets differed in protein content (21, 19, 17and 15%), but isocaloric (2,900 kcal ME/kg). Ten (5 males, 5 females) day old chicks were allocated as replicate and thetreatments were 2 lines x 4 levels dietary protein. The trial was conducted for 12 weeks period . Bodyweight gain of Kampungchicken (704 g/bird) was lower than ofPelung cross chicken (844 g/bird). Based on bodyweight gain and feed conversion ratio,the optimum level of dietary crude protein was 19% for both lines, whilst consumption was not affected either by lines nor bydietary protein. Pelung cross chicken converted feed to body weight more efficiently than Kampung chicken did. However feedconversion ratio increased with decreasing in dietary protein. Mortality was not affected either by lines nor by dietary protein.Twelve weeks carcass percentage of Pelung cross (64,9%) was higher than of Kampung chickens (62,9%), however carcass percentage was not affected by the dietary protein. Abdominal fat pad was not affected by lines of chickens nor dietary protein. Key words : Native chicken, protein, growth, carcass

One hundred and eight pullets of 13 weeks old white Tangerang-Wareng, were allocated to numbers of wire cages. Each cage had 4050 cm2 floor space. The treatments were three cage-densities (4, 6 and 8 pullets/cage) with six replications for each treatment for growth observation, while there were other three treatments (observation times), which were 07.00-08.00 (morning), 12.00-13.00 (noon) or 17.00-18.00 (afternoon), that were applied and replicated in three for behavior observation. Commercial ration containing 20.86% crude protein, 3.22 Ca, 0.87% total P and 2982 kkal metabolizable energy (ME)/kg and drinking water were provided ad libitum. Results showed that cage density neither significantly (P<0.05) affected birds’ final bodyweight, bodyweight gain, feed consumption nor feed conversion ratio. Analysis of variance showed that there was no interaction effect of cage densites and observation times on every observed behavior variable, except on standing activity. Cage density did not significantly (P<0,05) affect behavior, except behavior of cleanning, which increased with the increase of space allocation. The presentages of eating and pecking were significantly increase in the morning, while presentage of bird having a rest increased at noon. Drinking behavior was not affected by both cage density and observation time. The most birds showed the highest activities in the morning. In general the most cage density of 8 birds/4050 cm2 of floor space (506 cm2/bird), was more likely comfortable to the birds to live.
