Abstract

The purpose of this study was to know productivity and repeatability of local pigeon. Data werecollected from 124 birds that reared under intensive management. The results showed that artificial pairwas 100% and polygamy was 16% (n=62 pair of pigeon). The ration of local pigeon consisting of 50%corn+50% of commercial feed for starter broiler chicken can be applied in field. The average of eggproduction was 1.8 eggs/pair/period, egg weight was 17.7 g, fertility was 96.6%, hatching rate was 77%,embryo mortality rate was 23%, interval period from laying to hatching and suckling was 51 days, 31.4days with hatching, and 17.6 days without hatching and suckling. The day old pigeon weight ranged10.9-16.2 g. Repeatability value of productive traits was high, in which egg weight was 0.64 and day oldpigeon weight was 0.737. Repeatability of reproductive traits was low, that was fertility and hatchabilitywas 0.12 and 0.048, respectively). The squab weight increased from week 0 to 4, then decreased in theweek 5. The growth rate was highest at the week 1, then decreased from the week 2 to 5 with thenegative growth rate occur at the 5th week. The squab growth rate followed a quadratic pattern. It wasconcluded that slaughter squab selection could be done at 4th week old.

Abstract

Kampung chicken is one of Indonesia native chickens which has slow growth and it needs to be improved. Growth is a quantitative trait which is controled by many genes. One of the genes which plays a crucial role in controling growth is IGF2 gene. The objective of this study was to analyze the association of IGF2 gene polymorphisms with growth traits in kampung chicken. A total of 56 male and female chicks were maintained for 16 weeks and genotyped using PCR-RFLP method.Result showed there was TC muation on IGF2 gene and it was polymorphic in kampung chicken. Frequency of heterozigous TCwas the highest than the others. There was no association between IGF2 gene polymorphismswith growth traits in kampung chicken. It can be caused by the synonimus mutation on IGF2 sequence that does not alter the amino acid. Bot of the nucleotides coded for histidine. It may not give different effect toward the growth traits in kampung chicken.Keywords: growth traits, IGF2 gene, kampung chicken, polymorphisms

Abstract

The aim ofthis study was to examine the preservability of local chicken semen in extender added with various level extra virgin olive oil (EVOO).Semen was collected from three roosters using massage method. Immediately after collection the semen evaluated macro and microscopically. Semen demonstrated   motility, individually divided into five tubes. Each of them diluted with ringer fructose that supplemented with 0%, 4%, 6%, 8% or 10% EVOO. Semen was stored in  refrigerator (5 oC) for sixty hours and evaluated every twelve hours for spermatozoa motility and viability. Results revealed that supplementing the diluent of roosters semen with EVOO and then storing it for different storage periods (, , ,  or  hours) resulted in significant (p .) improvement in spermatooa motility and viabilityin comparison with the control group.Moreover, used of 8% EVOO surpassed other treatments afterin vitro storage for up to 60 hoursand resulted fertilizing ability up to 73.81%.This research conclude that 8% EVOO can be used as antioxidant source for roosters semen during preservation.Keywords : extender, local chicken, extract virgin olive oil, sperma

Abstract

Kampung chicken is Indonesian native chicken that potential to be developed as commercialchicken.  The large-scale breeders less interest to breed kampung chicken because it has slow growth toreach slaughter weight than commercial meat type. Therefore, kampung chicken’s performance needto be improved by crossing with commercial meat type that has fast growth. This research purposedto observed the effect performance of first generation (F1) from commercial meat type crossing withkampung and their reciprocal.  Research conducted performance of crossing chicken in age 0-12 weeksage. T test used for knowing difference body weight mean, body weight gain, feed consumption, and feedconvertion rate.  The result of this research were not significant between KB cock with BK cock andKB hen with BK hen on body weight, body weight gain, feed consumption, and feed convertion rate.Whereas mortality percentage BK chicken was higher than KB chicken althought less of mortality.  KBand BK cocks had better performance than hens. Reciprocal crossing between kampung chicken andcommercial meat type had performance better than kampung chicken, so crossing had been increasedgenetic quality of kampung chicken.

Abstract

Local chicken in Indonesia is commonly maintained traditionally for meat consumption so that ithas the potential to be developed as an economical livestock commodities. The increasing of meat local chicken demand should be followed by the increasing of its quality. FMO3 gene as a gene that control meat quality especially controlling fish odor in livestock product, can be used as a functional gene in its function as a genetic marker. This research was aimed to identify the FMO3 gene polymorphism in exon 6 inbroiler, kampung,sentul, merawang, pelung and nunukan chicken population. Identification of polymorphism was used 129 samples from those populations. AlwnIenzyme was used in PCR-RFLP technique to digest PCR product overnight.Genotypingshowed only AA genotype (275/249 bp) in 524 bp product amplification. There was no polymorphism found in every population. It needs further study in the different sequences to findthe polymorphism of FMO3 in local chicken.

Abstract

This study aimed to identify the GHSR genes polymorphism in chickens and to analyze the association of these genes on carcass weight and commercial cuts in chicken. A total of 60 local chickens (33 hen and 27 roosters) was used in this study. The chickens were bred in the colony cages and given full time access (ad libitum) to the commercial feed. The PCR-RFLP method was used to analyzed the gene polymorphism. The Hin6I was used as a restriction enzyme. The genotype frequency, allele frequency and Hardy Weinberg equilibrium were analyzed in this study. The phenotypic characteristics (body weight, carcass weight, breast weight, thigh weight, drumstick weight, wing weight and back weight) were analyzed using T test. The result showed that there were two genotypes (CT and TT) found in kampung chickens. The frequency of CT and TT genotype were 0.317 and 0.683, respectively. The value of Ho and He were 0.317 and 0.267 respectively. This population was not equal according to Hardy Weinberg  equilibrium analysis. The GHSR gene polymorphism was significantly associated (P<0.05) with  body weight, carcass weight, breast weight, thigh weight, drumstick weight, wing weight and back weight. The TT genotype was higher than CT genotype on all traits. The locus of GHSR|Hin6I could be used as a marker associated selection (MAS).
