Abstract

High egg production and good egg quality for IPB D3 chicken is very important to produce a lot and quality DOC, then a high repeatability value is also needed to maintain continuous DOC availability. The purpose of this study was to examine the estimated repeatability value of egg production and eggquality as well as the production performance and quality of chicken eggs IPB D3. The observed poultry were 30 IPB D3 G3 females and 90 eggs. Repeatability values were analyzed using a variance table and egg production and quality data were analyzed descriptively. The repeatability value of egg production is 0.42 (high), the Haugh unit repeatability of egg is 0.40 (medium), the egg weight repeatability value 0.67 (high), the egg yolk score repeatability value 0.40 (medium) and the egg index repeatability value 0.95 (high). Egg weight 40.76 g, Haugh unit value 76, and egg production 44.8%.

Abstract

Bogor Agricultural University local chicken which named IPB-D3 is a prospective male line obtained from the chicken selection program IPB-D1. The establishment of IPB-D3 chickens aims to produce local chickens with fast growth weight. This research aims to evaluate the performance of local chickens from IPB-D3 Generation 4 (G4) and its heritability values. The observed samples include 10 males and 30 females of IPB-D3 chickens of Generation 3 (G3) aged 21-40 weeks as parent and 100 Day Old Chickens (DOC) IPB-D3 G4 up to 12 weeks old. The results obtained that IPB-D3 G4 chickens show an average body weight for males 1021.44 g and females around 648.33 g at the age of 12 weeks. The feed given to IPB-D3 G4 chickens is the same as the parents, namely it has nutrients below commercial feed because the feed given uses a mixture of local feed which are bran and corn which already used in Sinar Harapan Farm Sukabumi. Weight gain is the change in body weight that occurs over a specific period, and the weight gain of IPB-D3 G4 chickens is relatively fast, especially from the 2nd to the 3rd month, with a weight gain rate reaching 406.27 g. Growth rate from IPB-D3 G4 chickens experiences a slowdown at the age of 2 months and falls below their optimal growth rate. Another aspect to report is the mortality rateof IPB-D3 G4 chickens, which is quite high at the DOC and female age due to environmental conditions and disease attacks. However, the mortality rate decreases with the increasing age of the chickens, and no deaths are found in 12 weeks old male chickens. The heritability value of body weight in IPB-D3 G4 chickens is high at the age of 4 weeks and can be used as a basis for selection based on body weight.

Abstract

Myoglobin (MB) gene encodes the protein of myoglobin, which is a protein found in muscle tissues that plays a crucial role in binding and storing oxygen. This study aimed to analyze the polymorphism of the MB gene, examine its relationship with the meat mineral content, and analyze its expression in the liver and thigh muscle tissue of IPB-D2 chicken. A total of 55 IPB-D2 chickens were used in this study. Identification of the gene polymorphism, quantification of the mineral content, and gene expression were performed using the direct sequencing method, the Atomic Absorption Spectroscopy (AAS) method, and the qRT-PCR, respectively. Chicken thigh muscle and liver tissues were used as the source of mRNA in this study. The statistical analysis methods used were the chi-square test to test Hardy-Weinberg equilibrium, and the T-test for mineral association analysis and gene expression analysis. IPB-D2 chicken on average contains 17.81, 0.22, 16.50, and 0.34 mg/kg of Fe, Se, Zn, and Mn, respectively. Two SNPs were found in 5’UTR of the MB gene, namely SNP g.17 G>T and SNP g.25 T>C. Genotype TT (g.17 G>T) and genotype CC (g.25 T>C) were significantly (P<0.05) associated with high Fe content in IPB-D2 chicken. The gene expression analysis showed that MB mRNA expression in the liver was not statistically different between high Fe (TT/CC) and low Fe (GG/TT and GT/TC) genotype combination. Meanwhile, in the thigh muscle, MB mRNA expression in TT/CC genotype combination was significantly higher than GG/TT and GT/TC genotype combination (P<0.05). These results suggest that the identified polymorphisms in the IPB-D2 MB gene could serve as references for investigating similar gene in other chicken breeds, especially regarding Fe, Se, Zn, and Mn mineral content.

Abstract

Research on the 11 morphometrics of IPB-D chicken in Sukabumi district has not been conducted. This study aimed to evaluate the morphometrics of IPB D1, IPB D2 and IPB D3 chickens in Sukabumi District. The design of this study was a completely randomized design with 3 levels of treatment linesnamely IPB D1, IPB D2 and IPB D3 with 95% confidence interval. Treatments that had a significant effect were followed by the Tukey test. Measured morphometric parameters such as shank length, shank circumference, femur length, tibia length, breast length, breast width, breast depth, breast circumference and back length. IPB D3 chickens show that their genetic condition is not yet stable as meat type. At the age of 4 to 8 weeks, IPB-D3 chickens have a larger size in the variables of shank circumference, femur length, tibia length, breast length and breast circumference. However, at the age of 8 to 12 weeks IPB-D3 chickens have a smaller size in the variables of breast length, breast width, breast depth, breast circumference and back length. Meanwhile, IPB D1 chickens show that they are genetically stable and IPB D2 is able to adapt because of its resistance traits.
