Sensi-1 Agrinak is a strain of the improved native chickens for meat production in Indonesia. The objective of this study was to investigate influence of different dietary energy and protein levels on performance, meat bone ratio, and meat chemical composition of Sensi-1 Agrinak chicken, reared until 10 weeks of age. Two hundred and sixteen of unsexed day old chickens (DOC) of Sensi-1 Agrinak were subjected to six experimental rations differed in dietary crude protein (CP) content,. Namely: 21;19; and 17 % and dietary metabolizable energy (ME) (2800 and 3000 kcal/kg). Each treatment combination was replicated four times and fed from day old to 10 weeks old. In each treatment combination there were nine unsexed-DOCs. The parameters observed were performance (i.e. live weight, feed intake, viability, FCR), economic index (European Production Efficiency Factor/EPEF), meat bone ratio, and meat chemical composition. Result showed that increased of dietary CP level increased live weight and EPEF (p<0.05). Sensi-1 Agrinak chicken had the best FCR (2.59), when fed diet containing 21% CP and 3000 kcal/kg. Increased dietary CP level increased the meat-bone ratio of breast, thighs, and drumsticks. Meanwhile, increased levels of dietary CP and ME did not affect (p>0.05) meat chemical composition. It is concluded that optimal dietary levels of crude protein and energy for unsexed Sensi-1 Agrinak chicken up to 10 weeks of age were 21% CP and 3000 kcal/kg.

One of local chicken breeds develop in Indonesian Research Institute for Animal Production (IRIAP) is local SenSi-1 Agrinak chicken. This new improved local-meat-type breed was released with Ministry Agriculture Decree Number 39/Kpts/PK.020/1/2017 on 20th January 2017. SenSi-1 Agrinak was originally selected from native Sentul chicken breed obtained from Ciamis district in West Java Province. Selection criteria were two feather colors of grey or black spotted white (pucak), which were applied to both males and females. Pea-comb type was also one criterion for males, applied at the age of 10 weeks. Live weight at the age of 10 weeks with the selection intensity of 25% was applied to each generation of males chicken. Selection proceeded for six generations. Selection program was carried out under standard feed formulae containing around 17% crude protein with 2850 kcal ME/ kg, and containing other nutrients following the ones recommended for modern chicken of White Leghorn. Observation was conducted on each of about 2000 young chickens of grey and of Pucak SenSi-1 Agrinak both males and females age of 10 and 84 weeks. Results showed that grey SenSi-1 Agrinak chicken in total population, had: i) Grey feather color distribution of 55.51% in males, and 60.77% in females; ii) Yellow shank color of 52.51% in males, and 33.33% in females; iii) Pea type comb of 90.98% in males, and 89.23% in females; iv). Ten weeks live weight of 886.38+142.93 g/bird in males, and 739.17+ 118.87 in females. Pucak SenSi-1 Agrinak chicken in total population, had: i) Pucak feather color of 75.65% in males, and 8330% in females; ii) Yellow shank color of 51.91% in males, and 36.59% in females; iii) Pea type comb of 91.55% in males, and 92.28% in females; iv) Ten weeks live weight of 908.76+ 130.98 g/bird in males, and 750.53+ 110.56 g/bird in females. Whilst for grey SenSi-1 Agrinak male chicken after selection had live weight at 10 weeks old of 1015+107 g/bird, and for Pucak SenSi-1 Agrinak male chicken was 1051+76 g/bird. This initial performance information for those two breeds of considerably improved local chicken can be used as the base of information for SenSi-1 Agrinak breed for male line of meat type of local chicken breeding.

SenSi-1 Agrinak chicken is Indonesian local chicken that was selected for growth rate for six generations. The aim of this study was to estimate of carcass weight and carcass cuts of female SenSi-1 Agrinak chicken, based on age and live weight. The chicks were reared intensively in colony wire cages and they were slaughtered with Islamic method when they reached age of 5, 8 and 15 weeks. Empty carcass and carcass cuts were weight in fresh. Data were analyzed using correlation and regression analysis method. Results showed that the live weight had a high positive correlation to carcass weight and carcass cuts weight of female SenSi-1 Agrinak chickens aged 5, 8 and 15 weeks. Estimation of live weight, carcass, carcass cuts, gizzard, liver and abdominal fat of female SenSi-1 Agrinak, using mathematical model, showed small value differences (0.09 - 4.43%) from the actual data. It was concluded that female SenSi-1 Agrinak chicken’s carcass weight and carcass cuts, could be estimated based on of age in days and live-body weight in gram without slaughtering.

KUB-2 line of chicken has improved local chicken selected from the KUB-1 chicken line. KUB-2 was selected for more egg production and yellow shank. KUB-1 chicken has 64% various of black feather color, which sometimes tends to have unpreferred dark carcass. Yellow shank color has a positive correlation with the skin color of carcass. As many as 517 pullets of KUB-2 at 4th generation were divided into two groups of 194 pullets of KUB-2kk (yellow shank) and 323 pullets of KUB-2nk non-yellow shank). The chickens were raised intensively in the individual cages for the 24 weeks observation. Variables measured were age at first egg (AFE) bodyweight at first egg (BWFE), egg weight at first egg (EWFE), average egg weight (AEW), average egg production (AEP) during 24 weeks, feed conversion ratio (FCR) of 25-43 weeks of age, and mortality. The result showed that there was no statistically significant different (p>0.05) between KUB-2nk and KUB-2kk respectively for AFE of 156.2 d and 158.1 d, for BWFE of 1788 g and 1808 g, for EWFE of 31.32 g and 31.34 g, for AEP24 of 103.3 eggs or 61.5% and 101.9 eggs or 60.7%, and for FCR25-43 of 3.53 and 3.54. AEW increased with increasing age of hen, the mortality of the whole population was 0.98%.

The aim of doing this experiment was to observe the growth response of improved native breeds of chicken under diets differed in energy and protein content. Three groups of improved native breeds, obtained from mating of ♂KUB to ♀KUB (Line 1), of ♂SenSi to ♀KUB (Line 2) and of ♂Gaok x ♀KUB (Line 3), were subjected to three experimental diets, differed in metabolizable energy (ME) and crude protein (CP) content. The experimental diets consisted of Diet 1 (2,800 kcal ME/ kg with 17,81% CP), Diet 2 (2,950 kcal ME/ kg with 18,61% CP) and Diet 3 (3,100 kcal ME/ kg with 19,25% CP). The experiment was designed as factorial 3 x 3 with 7 replications of each treatment combination, consisted of 5 birds per treatment combination. The chickens were raised up to 10 weeks of age. Results of the experiment showed that Line 2 (♂SenSi mated to ♀KUB) had highest body weight at 10 weeks of age (P<0.05), lowest feed conversion ratio (FCR) and highest European Production Efficiency Factor (EPEF), compared to other two lines. The appropriate diet for Line 2 was Diet 2. It could be concluded the crossbred line that was resulted from crossing of ♂SenSi to ♀KUB (Line 2), had potential to be used as improved native chicken for the industry in Indonesia supported by appropriate diet containing 2,950 kcal ME/kg with 18.61% crude protein.
