Abstract

Earthworm meal (Lumbricus rubellus) has become one of natural material that could be used asfeed additive. Powdering method of earthworm was done by using formic acid addition. The study wascarried out (1) to evaluate the essential amino acid profile of earthworm and earthworm meal, (2) tocalculate the value of essential amino acid index (EAAI) of both materials. A modified EAAI equationwas developed from the essential amino acid profile of earthworm and earthworm meal. The resultshowed that essential amino acid of earthworm was dominated by histidine (0.63% of dry matter basis),meanwhile the earthworm meal was dominated by isoleucine (1.98% of dry matter basis). The nonessential amino acid of earthworm and earthworm meal was dominated by glutamic acid (1.52% and3.60% of dry matter basis respectively). The value of essential amino acid index obtained fromearthworm meal was higher (58.67%) than those from earthworm (21.23%). It is concluded thatpowdering method of earthworm by using formic acid addition had higher amino acid balance thanearthworm.

Abstract

The objectives of this study were to detect the Mendelian mode inheritance of growth hormone(GH) and to establish genotype frequency of GH gene in Ongole-crossbred cattle mated by the artificialinsemination (AI) technique. Total of 76 blood samples were collected from Ongole-crossbred cows andbulls (G0), and their progenies (G1) at the Tumaratas AI service center in North Sulawesi province,Indonesia. All blood samples were screened for the presence of GH locus using a PCR-RFLP methodinvolving restricted enzyme Msp1 on 1.2 % of agarose gel. Data were analyzed using statistical programfunction in Excel XP. The results showed that GH locus using alleles of Msp1+ and Msp1- enzymerestriction in Ongole-crossbred cows and bulls was inherited to their Ongole-crossbred progeniesfollowing the Mendelian mode inheritance. This Mendelian inheritance generated by AI technique wasnot under genetic equilibrium for the Msp1 genotype frequencies in groups of G0 and G1. The breedingprogram using genotypes of bulls and cows (G0) for generating the genotype of GH Msp1 enzymerestriction by AI technique should be maintained to increase these various allele dispersion rates forbreeding under genetic equilibrium of the Ongole-crossbred cattle population.

Abstract

The aim of this study was to identify the polymorphism of leptin gene and its association with growth traits in Kebumen Ongole Grade cattle. One hundred blood samples were collected for molecular analysis. Polymorphism of the leptin gene was analyzed using Polymerase Chain Reaction - Restriction Fragment Length Polymorphism (PCR-RFLP) with HpyCH4V restriction enzyme and DNA sequencing. Association analysis of the leptin gene with growth traits was analyzed by T-test. The results showed that SNP g. 1180 C>T was found in the population.The SNP changed amino acid from arginine to cysteine. The SNP was significantly associated with a high chest circumference at weaning age in animal having CC genotype (P<0.05). There were two identified alleles, namely C and T, with frequencies were 0.885 and 0.115,respectively. The genotype frequencies of CC, CT and TT were 0.78, 0.21 and 0.01, respectively. Allelic and genotypic distribution in the studied population were in Hardy-Weinbergequilibrium. Animals with CC genotype had a higher circumference at weaning age (WCC) than those with CT genotype. In conclusion, SNP g. 1180 C> T in the leptin gene is potential as genetic marker for growth traits in Kebumen Ongole Grade cattle.

Abstract

The purpose of this research was to find out the effects of liquid turmeric extract (LTE) supplementation as a phytobiotic on carcass production and chemical quality of broiler chicken meat. The research is conducted with a directional pattern completely randomized design. Eighty-four broiler chickens were raised from day old (DOC) to 42 days old chick. From DOC to 14 days old chicks were fed with commercial feed (ME 3,100 kcal/kg; CP 22%; Ca 1%; P 0.75%). During 15-21 days of age given a commercial feed mixture and basal feed (ME 3,201.77 kcal/kg; CP 20.21%; Ca 0.90%; and P 0.43%). At 22-42 days old given treatments. Seven treatments were replicated 3 times consisted of 4 broiler chickens for each replication. The treatments were positive control (P1), negative control (P2), water + LTE 2% (P3), water + LTE 4% (P4), water + LTE 6% (P5), water + LTE 8% (P6), and water + LTE 10% (P7). The results showed that LTE 10% significantly decreased (P<0.05) on the slaughter weight and 8% until 10% dossage had a significant decrease (P<0.05) on the meat water content. However, it did not show a significant influence (P>0.05) on the carcass weight, carcass percentage, meat protein and fat content.

Abstract

The objectives of the research were to investigate the behavior of dairy farmers and factorsaffecting the effort to enhance the economic of scale. Survey was conducted on 75 dairy farmers atGetasan District, Semarang Regency. Samples were drawn in random from villages of Jetak, Batur andTajur, 25 farmers each. The data were analyzed by logit model regression, using 15 indicators ofbehavioural approach and socio-economic factors as predictors (independent variables) i.e. ages, formaleducation, family size, experience in cattle rearing, number of cattle raised, production of milk and landoccupation. The result showed that 40.04% of the farmers were good, 33.07% were moderate and20.89% were low risk takers. The farmers’ behaviour in enhancing economic of scale significantlyinfluenced by the farmers’ age, milk production and number of cattle reared. The odds ratio of ages,milk production and number of cattle reared were 0.93; 1.32 and 1.37, respectively. These valuesindicated that as values of ages increased as much as 1 year, the values of the willingness on risk takingwill decrease as much as 0.93 times; the values of milk production increase as much as 1 litre, the valuesof the willingness on risk taking will increase as much as 1.32 times; and the values of the number ofcattle increased as much as 1 AU, the values of the willingness on risk taking will increase as much as1.37 times.

Abstract

The aim of this research was to analyze the correlation of age of Bali bull to the body weight and semen qualities. The materials were 50 Balibulls data collected from 2012 to 2018. Therecordeddatawere consisted ofsemen productions (n = 1304) and body weight (n = 1544). The observation was conducted to analysis the interrelationship between the Bali bulls age and body weight (BW), to the semen volume (SV), individual motility (IM) and sperm concentration (SC). The obtained data was analyzed with One-Way ANOVA analysisby using SPSS 24 and followed with Duncan’s Multiple Range Test to determine any significant differences. The correlation between Bali bulls age (the independent variable) and semen quality (the dependent variable) was computed by using Pearson correlation method and presented in linear regression models. The results showed that the Bali bulls agesignificantly affect (P<0.05) the BW from the age of 1 to 10 years old. The age also showed a significant effect (P<0.05) on the semen qualities. The age correlated significantly (P<0.05) with BW, SV, IM, SC were 0.658, 0.386, 0.134 and 0.086, respectively. Inconclusion,the age of Bali bull could be used as an indicator todetermineits BWand semenqualities.

Abstract

It was indicated that layer smallholders awareness of biosecurity was low. This paper aimed todetermine the level of adoption within the South Sulawesi layer smallholders of a range of standardbiosecurity measures. Sidenreng Rappang (Sidrap) regency was chosen as a location of the research,because it was famous as a central of layer smallholders. Total sample was 60 respondents. The samplewas chosen through random sampling from two districts which were the most populous of layersmallholders, namely Baranti and Maritengae. Data were collected using structured questionnaires anddepth-interview. The data were tabulated and analysed using a simple method of scoring with regard totheir biosecurity status. The status of biosecurity was used to know the level of biosecurity adoption.Biosecurity status was obtained based on the adoption of biosecurity measures which consisted of 9stages: farm inputs, traffic onto farms, distance from sources of pathogens to shed, exposure of farm,biosecurity at farm boundary, biosecurity between farm boundary and shed, biosecurity at the shed door,traffic into the shed and susceptibility of the flock. Using adoption index, this research revealed thatbiosecurity adoption of layer smallholders in South Sulawesi was classified into a “partial adopter”.
