Goats are one of the mainstay commodities for farmers in rural areas, especially in several development centers in the West Sulawesi region, Indonesia. Generally the local goats that are kept are Kacang goats which are the type of meat production, but since the introduction of the Etawa breed most of the goat population that is currently being kept is from the Peranakan Etawa (PE) goat which is a cross between Kacang and Etawa goats which later develop into dual-purpose goats (meat and milk). The purpose of this study was to characterize the phenotypic (qualitative and quantitative) properties of Peranakan Etawa (PE) goats which were maintained by communities in the West Sulawesi region, Indonesia. This study used a survey method by identifying the qualitative and quantitative performance of the PE goat population. Characterization activities carried out were to identify the performance criteria of qualitative traits which included the characteristics of coat color, horn and ear shape and quantitative properties such as body weight, height, body length and chest circumference and chest width. A total of 113 goats (111 females and 2 male Peranakan Etawa breeds) were selected to be used as samples from the existing goat population. Peranakan Etawa breeding performance based on morphometric data included the characteristics of shoulder height (67.98 ± 5.61 cm), back height (71.34 ± 5.73 cm), body length (71.70 ± 6.46 cm), chest circumference (72.19 ± 6.46 cm), chest width (15.41 ± 1.86 cm) and body weight (33.04 ± 6.09 kg). The qualitative and quantitative performance of Etawa breeds in West Sulawesi is very diverse and need genetic improvement to meet Indonesia National Quality Standards (SNI).
Black soldier fly larvae or maggot (Hermetia illucens) is one type of insect that meets the requirements as alternative protein source of feed. The purpose of this research is to obtain high quality feed production. This research will be carried out in the Animal Husbandry Department of Unasman for the rearing and the nutrition analysis will be carried out in the Feed Chemistry Lab, Faculty of Animal Husbandry, UNHAS. This study was designed using a completely randomized design (CRD) consisting of 5 and 3 replications. The treatments in this study are as follows: A0: 5 days, A1: 10 days, A2: 15 days, A3: 20 days, A4: 25 days. The results obtained are the rearing period that significantly affect the levels of dry matter, crude fat, and crude protein of black soldier fly maggot (Hermetia illucens) and doesn’t have significant effect on crude fibre levels. The rearing period of 25 days (A4) has the highest dry matter content that is 30.47%. Crude fat at 25 days rearing time (A4) is 34.09% significantly higher than A0 (22.09%), A1 (24.82%) and A2 (26.79%). Maggot with a rearing period of 20 days (A3) has the highest crude fibre content of the other treatments that is 10.50% and the lowest is A0 (9.07%). The A0 (49.91%) treatment is significantly higher than A2, A3, and A4. The longer the rearing period of Hermetia illucens maggot, the level of dry matter, crude fat and crude fibre tends to increase. However, the crude protein decrease, although not significantly.
Some important genes are involved in controlling the reproductive trait of goats, one of which is the Melatonin Receptor 1A (MTNR1A) gene. The MTNR1A gene is known with seasonal reproductive activity and related to lambing frequency in the goat. The purpose of this research was to determine the genetic polymorphisms of the MTNR1A gene in Kacang, and Peranakan Ottawa (PE) goat population reared traditionally in South Sulawesi region of Indonesia. In total 253 heads of goat consist of 137 heads of Kacang and 116 Peranakan Ottawa from South, Sulawesi region was used as research samples for blood collection. The blood samples were collected from the jugular vein, which was then continued for DNA extracted by using a DNA extraction kit. The MTNR1A genotype was identified by PCR-RFLP technique using restriction enzyme RsaI. The result showed that there was genetic diversity in the MTNR1A gene in Kacang and PE population with the obtained of two alleles R and r. The common allele was R with frequency 0.93 in Kacang population while in PE population was 0.89. The r allele was 0.06 and 0.10 in Kacang and PE population, respectively. The most common genotype found in the population was RR (0.95), while Rr was only 0.05 and rr genotype did not found in this population. Observed heterozygosity value was 0.05. According to the Hardy-Weinberg test, this population was in equilibrium for MTNR1A gene. In conclusion, this finding indicated that there was genetic diversity exists in local goat population, and future research needed to find any association with this genetic variation with reproductive performance, the data obtained from this study could be used for the strategic program in goat breeding to increase reproductive performance of local goat especially fertility traits.
Singing chicken is germplasm, genetic resources, indigenous chicken in Indonesia and be known of their unique, exclusive, superiority of singing style with long-melodious rhythm, and different crowing style-tone-tempo comparing with other singing chickens breeds in the world. Some crowing character information was needed to optimize conservation and utilization strategies. The aim of the study was to compare crowing duration and number crowing syllables four singing chicken breeds in Indonesia (Bekisar, Kokok Balenggek, Pelung and Gaga’). This research used 532 birds Gaga’ chicken from Sidrap, Barru and Maros Districts, South-Sulawesi province, Indonesia. They were separated based on crowing speed into Slow-group (234 birds) and Dangdut-group (298 birds). Then, Dangdut-group has separated again, based on total number crowing syllables, into Long-Dangdut-type (51 birds) and Short-Dangdut-type (247 birds). All crowing sounds were recorded and computerizing digitalized using Cool Edit Pro. Software to visualized bioacoustic character as a wave form then data interpreting for analyzing mean and standard deviation. Average crowing durations of Pelung, Kokok Balenggek, Bekisar and Gaga’ chicken (Short-Dangdut-type and Slow-group) were 2.0 to 10.0 sec. Dangdut-Long-type was the longest crowing duration (30.5 sec) and the highest number syllables (140.92). Average number syllables of Pelung (3 sec), Kokok Balenggek (3 to 12 sec) and Bekisar (2 sec) chicken were less than Gaga’ chicken (Dangdut-Long-type: 140.9 sec, Dangdut-Short-type: 20.9 sec and Slow group: 8.2 sec). Each singing chicken breed in Indonesia have uniqueness and differences crowing character. A crowing character such as crowing duration and number of syllable could be identified as one of basic selection to promote and to maintain conservation of singing chicken as germplasm of Indonesia.
The purpose of this study was to evaluate carcass and non-carcass characteristics of local ducks. The research material was carcasses of five local male ducks aged 24 weeks (relative weight of about 1220 g) and five male Pekin ducks of 9 weeks of age (relative weight of about 1440 g) which were kept in the duck cage at the laboratory of Breeding and Genetics, Faculty of Animal Science, Hasanuddin University, Indonesia using intensive housing systems and commercial feed. The research method was all ducks were fasted and rested for 8 hours, slaughtered, carcasses, and parameters analyzed. Parameters measured were weight and percentage of carcass traits (wings, dorsal, thighs, breast, and neck), weight and percentage of non-carcass traits (head, shank, kidney, heart, trachea, esophagus, gizzard, liver, intestine, feathers), three types of weight (live weight, slaughter weight, and carcass weight), percentage of the total carcass, and meat bone ratio (thigh and breast). The results showed that there were no significant differences in all carcass and non-carcass parameters between local ducks and Pekin ducks except for non-carcass parameters, namely head, gizzard, shank, intestine, heart, and trachea. At different ages, Pekin ducks and local ducks showed similar carcass characteristics. These results show that the growth rate of Pekin ducks is faster than that of local ducks. These results become one of the bases and references that local ducks still need a breeding program for improving carcass growth to reach optimum carcass characteristics.
