Abstract

Point mutation on exon 2 of leptin gene, which changes amino acid encoding from Arginine to Cysteine, may alters the physiological function of the leptin hormone. This study aimed to identify leptin gene polymorphism of Ongole Grade (OG) cattle based on Single Nucleotide Polymorphism (SNP). The DNA sample was taken from 48 head of OG cattle at Balai Pengembangan Perbibitan Ternak Sapi Potong(BPPT SP) Cijeungjing West Java, which was isolated from white blood cell using the high salt method. Amplification of DNA was done by Polymerase Chain Reaction (PCR), followed by direct sequencing to obtain nucleotide sequence. The SNP analysis was carried out from alignment of sequencing result using Bioedit and MEGA 5.2 program. The results indicated in exon 2 leptin gene of OG cattle there was one synonymous SNPs that did not changeamino acids Serine encoding on g.1025T >C/S17S, while two non synonymous SNPaltered amino acids encoding, those were g.1047C> T /R25C and g.1048G>A/R25H. Those mutations changed amino acids encoding from Arginine to Cysteine and Arginine to Histidine respectively.In OG cattle, the frequency of A allele (44.8%) was higher than C allele (33.3%) and T allele (21.9%). Six genotypes were also identified, i.e. AA (41.7%), CC (20.8%), CT (20.8%), CA(4.2%), TT (10.4%) and TA (2.1 %). Heterozigosity of OG cattle based on leptin gene was 0.65 that was a high category. The A allele was a specific allele on Indonesian local cattle.

Abstract

An estimation of most probable producing ability (MPPA) value based on the calves performance is very important for the cow selection. The birth data record of 48 Sumba Ongole (SO) cows and record data from 52 callf birth’s performance were used to estimate the value of MPPA. High of r value (r > 0.30) was obtained at the body length (BL). Birth weight (BW), withers high (WH) and chest girth (CG) had a moderate value (0.10 < r < 0.30) of repeatability. The MPPA value of the cumulative calf birth’s performance of cows based on the highest birth records was 4.64 (cow number 3770) and the lowest was -4.64 (cow number 2283). Calf number B2076 (cow number 3586) had the highest ratio of WH (115.70); BL (124.26); CG (118.90), while the highest ratio of BW (168.35) was obtained in calf number B2095 (cow number 3731). It was concluded that the BW of birth had a moderate value of r (0.10) and could be used as a selection criteria accurately.

Abstract

This research was conducted to study the influence of kapok seed oil (KSO) supplementation oncellulolytic enzyme and microbial fermentation activity. Sheep rumen fluid was used as enzyme sourceand inoculant, whereas carboxymethylcellulose (CMC) was used as the substrate. There were 4 levels ofKSO supplementation as treatment, i.e. : 0% (T0), 5% (T1), 10% (T2), and 15% (T3). Two measuredvariables were reduced sugar production rate and gas fermentation production. The data were analyzedby analysis of variance in completely randomized design. The result showed that reduced sugarproduction rate in T0, T1, T2 and T3 treatment groups were 2.58; 2.93; 2.08 and 1.58 mg/gCMC/minute, respectively, whereas gas production were : 15.97; 13.26; 10.54 and 7.57 mg/g CMC,respectively. Kapok seed oil supplementation up to 5% DM of cellulose substrate (CMC) did notinfluence the ruminal cellulolytic enzyme activity. The KSO supplementation level 10% - 15%decreased the ruminal cellulolytic enzyme activity.

Abstract

High occurrence of aflatoxin contamination in feed stuffs implicates for a long time experience ofaflatoxin B1 (AFB1) exposure to dairy cattle in Indonesia. A latin square 4X4 research design wasadopted to study the characteristic of AFB1 carry-over rate (COR) of Indonesian crossbred FriesianHolstein (PFH) as effects of inclusions of AFB1-naturally contaminated feed and bentonite in the diet.Results showed a rapid aflatoxin M1 (AFM1) excretion in the milk, detected in the first milking sampleor 10 hours after AFB1 ingestion. The steady state of AFM1 concentration observed since the first dayof treatment period and AFM1 contamination was still detected until 5 days after AFB1 removed fromthe diet. The COR in this study was observed 0.1%. AFM1 concentration was highly significantly(P<0.01) affected by treatments. However, there were no significant effects (P>0.05) of levels of AFB1and bentonite inclusions on the COR, nutrients intake, milk production, and milk composition. IIt isconcluded that AFM1 concentration was influenced by AFB1 intake and that transfer of AFB1-feed intoAFM1-milk (COR) in PFH cow was lower compare to reported COR value for dairy cow in sub tropicalregion.

Abstract

A feeding trial was conducted to study the use of natural limestone meal originated from Bukit Kamanglocated at Agam district of West Sumatra to substitute fresh water oyster shell as the main source ofcalcium in diet of laying hens. The mineral feed formula, as treatments, composed of limestone in combinationwith freshwater oyster shell in five different percent ratios: 100:0; 75:25; 50:50; 25:75 and 0:100. The mineralswere mixed in the level of 6 % into basal diet composed mainly corn, rice bran and concentrates. The fiveexperimental diets were then fed to 150 laying hens. They were divided into 5 groups; each group wassubdivided into 3 replicates groups containing 10 hens. Parameters measured included: feed intake, eggproduction, FCR, eggshell quality, Ca and P retention, tibia bone mineralization. Results showed the nutritivevalues of limestone of Bukit Kamang as mineral source of laying hen diet were found not significantlydifferent from those of oysters shell. The hens fed with diet supplemented with Bukit Kamang’s limestonetended to give better laying performances than those of supplemented with fresh water oyster shell. Thelaying performances, egg shell quality and Ca and P retentions did not significantly improved, when limestonewas mixed by oyster shell.
