Abstract

This study was aimed to analyze factors and models of business sustainability of smallholder layer farms in Kendal Regency, Indonesia. Purposive sampling method was used to select 120 active layer chicken farmers in Sukorejo, Pageruyung, Patean, Limbangan, and Boja Districts as research respondents with the ownership of 300 to 10,000 birds. Research variables consisted of three external variables (social, economic, and institutional) and two internal variables (income and business sustainability). Closed questionnaires were used to collect data. The data were analyzed descriptively using Structural Equation Modeling (SEM) by AMOS 21 software. The results showed that the exogenous and endogenous variables met the modeling criteria with Chi square value = 160.764; probability = 0.380; CMIN / DF = 1.031; GFI = 0.892; AGFI = 0.841; TLI = 0.998; CFI = 0.998; RMSEA = 0.016. Social, economic, institutional and income variables had a significant and positive influence (P≤0.05) on business sustainability. The constructed model had a strong and positive relationship, so it could illustrate the sustainability model of layer business in Kendal Regency.

Abstract

Objectives of this study were to compare the percentage of Sodium Chloride (NaCl) and cervical mucus profile which includes potential of Hydrogen (pH), abundance of cervical mucus, spinnbarkeit and ferning of dairy cattle at different age during estrus cycle. Thirty Two head of dairy cattle were used as materials which are 2 years old (n = 2), 3 years old (n = 18), 4 years old (n = 8) and 5 years old (n=4). Dairy cattle were estrus synchronized using 50 mg/head of prostaglandin. Data was collected on 48, 72, 78, 84, 90, 120, 144 and 408 hours after prostaglandin administration. The data were analyzed by using non parametric statistic which was Kruskal-Wallis H test. The significant data was tested with Mann-Whitney U test. The result showed that the abundance of cervical mucus was significantly different (P<0.05; χ2 = 0.011) on 84 hours after estrus synchronization. However, level of NaCl, abundance, spinnbarkeit and ferning of cervical mucus was not sigificantly different. In conclusion, the age of dairy cattle did not affected to the condition NaCl percentage, spinnbarkeit, pH and ferning of cervical mucus, but affected to the abundance of cervical mucus on 84 hours after adminitration of prostaglandine.

Abstract

The aim of this research was to evaluate the effect of feed restriction on growth hormone profiles and ovarian morphology during the growth period. Three hundred 14-day-old quails were used. The quails were maintained on two feeding restriction programs: two dietary regimes based on metabolizable energy (ME), R1 = 2900 kcal/kg and R2 = 2800 kcal/kg, and 3 quantitative feed restriction diets, P0 = 100% ad libitum; P1= 90% ad libitum and P2 = 80%ad libitum (n=300). Each group (n=50) was processed with five replications, 10 birds in each replicate. The change in growth hormone was determined at 28, 35, 42, and 49 days of age, while ovarian morphology was determined at sexual maturity. The results indicated that feed restriction induced a significant increase in growth hormone and insulin-like growth factor-1 after re-feeding. There was no significant effect caused by the rationing of metabolizable energy. The number of large yellow follicles was not different between quails fed with 100% ad libitum and 90% ad libitum. However, feed restriction significantly increased the number of small yellow follicles. In conclusion, the feed could be restricted to 90% ad libitum with a 2900 kcal/kg ration of ME and fed during the starter period (14 to 42 days of age) without influencing ovarian morphology in quails.

Abstract

The aim of this study was to evaluate the effect of simvastatin (SIM) and L-carnitine (LC) additives and their interactions, on productive performance and carcass quality of broilers. For this purpose, a feeding trial was conducted, under 3×3 factorial design, using SIM at 0, 1 or 2 g/kg level and LC at 0, 150 or 300 mg/kg level in a basal-diet and originating a total of nine treatments: T1 (control-diet, 0/0), T2 (0/150), T3 (0/300), T4 (1/0), T5(1/150), T6 (1/300), T7 (2/0), T8 (2/150), and T9 (2/300). Feed intake was higher in T2 (4716 g), T7 (4722 g) and T9 (4698 g) than in T1 (4545 g; P<0.05) considering the last growing phase (35-42 days) or whole 42-day production cycle. An improvement of feed efficiency was also observed in T8 (1.64) and T9 (1.67) when compared to T1 (1.77; P<0.05), and these were mainly due to SIM × LC interactions (P<0.05). The LC influenced positively (P<0.05) the weight of eviscerated carcass, breast, drumsticks and abdominal fat, as well as plasma triglycerides level. This findings suggests that the combination of SIM and LC additives have a positive influence on growth performance and carcass traits of broiler chickens.

Abstract

This study was conducted to evaluate the combination of ginger and turmeric extracts added with Lactobacillus spp. (GTL) on body resistance and productivity of broilers. 576 broilers with an initial body weight of 36 ± 0.99 g were used and were observed for 35 days. GTL containing ginger extract (0.2 g/liter), turmeric extract (0.4 g/liter) and Lactobacillus spp. (2,997 x 107 cfu/ml), and was given since 1-day old. Parameters observed were bursa fabriscius, spleen, and thymus weights, gluthationine peroxidase (GSH-Px), superoxide dismutase (SOD), Lactobacillus spp., Coliform, and Eschericia coli, feed consumption, body weight gain, and feed conversion ratio (FCR). A completely randomized design (CRD) was assigned with 3x4 factorial pattern (3 types of feed, 4 levels of GTL), with 4 replications (12 birds each). First factor, types of feed (A): self-formulated feed (A1), combination of self-formulated and commercial feed with 50 portion each (A2) and commercial feed (A3). Second factor, levels of GTL (B): 0 ml (B0), 2 ml (B2), 4 ml (B4) and 6 ml (B6) per litre drinking water. Data were subjected to ANOVA and continued to Duncan test at 5% probability. Results indicated that self-formulated feed with inclusion of GTL at 4 ml (A1B4) improve body resistance and increase production performance of broilers.

Abstract

A factorial design was used to analyzethe influenceofSauropus androgynusleaf extract (SALE) and turmeric powder (TP) on fat deposition in broilers fed high-fat diet. The first factor was the source of fat (6% beef fat and 6% palm oil), and the second factor was SALE plus TP [0 g SALE plus 0 g TP (G1), 9 g SALE plus 0.5 g TP (G2), 18 g SALE plus 0.5 g TP (G3), 9 g SALE plus 1 g TP (G4), 18 g SALE plus 1 g TP (G5)]. SALE plus TP affected cholesterol,lauric acid, myristic acid, palmitic acid, stearic acid and eicosapentaenoic acid contents (p<0.01).Fat sources affected fat, cholesterol, lauric acid, myristic acid, palmitic acid, stearic acid and eicosapentaenoic acid (p<0.01). There was a significant interaction between the two factorson fat, cholesterol, lauric acid, palmitic acid, stearic acid, and eicosapentaenoic acid contents. In conclusion, 18 g SALE plus 1 g TP supplementation to high-fat diet resulted in lower stearic acid, but it resulted in higher eicosapentaenoic acid. Supplementation of SALEplus TPto a high-fat diet lowered cholesterol content and changed fatty acidscomposition.

Abstract

This study aimed to investigate the diversity of the complete sequence of D-loop mitochondrial DNA (mtDNA) in Bali and Sumba Ongole (SO) cattlebreeds. A total of 24 blood samples were collected from Bali cattle (19 heads) and SO cattle (5 heads), and were extracted and then analyzed to obtain the sequence of D-loop mt DNA.Multiple alignments of the whole sequence of D-loop mtDNA were determined using clustal W. Genetic distance was calculated using a p-distance method, while the genetic tree was constructed using neighbor-joining (NJ) based on MEGA 6. Haplotype number, haplotype diversity (Hd) and nucleotide diversity (Pi) were analyzed using DnaSP version 6. As a result, the sequence of D-loop mtDNA in Bali cattle (921-1119 bp) and SO cattle (913 bp) was reported to have 8 and 4 haplotypes. Hd and Pi of Bali cattle reached 0.625±0.139 and 0.0266±0.0145, respectively, which wwere different from that of SO cattle, namely 0.900±0.1610 and 0.0064±0.0015, respectively. Specifically, we found 22 bp-repetitive nucleotide in Bali cattle, existing 3-9 times with a length of 66-198 bp present in D-loop mtDNA. This unique feature did not exist in SO cattle. Genetic distance and genetic tree determined according to sequence in hypervariability (HV-1) region of D-loop mtDNA (166 bp) resulted in satisfied separation, successfully classifying Bos javanicus, Bos indicus, and Bos taurus cluster.

Abstract

The study aimed at investigating the population, the protein profile and the ultrastructure of adult worms in the intestine of domestic chicken treated using Areca catechu crude aqueous extract. Fifty domestic female chickens of 6 weeks of age were assigned to 5 groups. Group A (negative control) was not given any treatment and any drug. Groups B, C and D were given the treatment at the doses of 26 mg/mL, 53 mg/mL and 79 mg/mL, respectively. Group E (positive control) was given Pyrantel®. Necropsy was conducted to all of the chickens 14 days after the treatment. Adult worms were collected and counted. The worms used in Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE) and Scanning Electron Microscopy (SEM) were those collected from the jejunum of the chickens in the groups A, B and C. The biggest number of the worms was found in the jejunum. The results of electrophoresis showed that the dose 53 mg/mL gave fewer protein bands than the negative control (21:12 ratio), while the results of the SEM showed that there was cuticle damage and anterior labia abrasion at the dose of 53 mg/mL. The Areca catechu crude aqueous extract showed anthelmintic activity potential by reducing the number of the adult worms, lowering their protein profile and damaging the A. galli worms in the intestine.

Abstract

The objectives of this study were to analyze and identify the β-LG genotype and examine its association with milk protein and milk production of Saanen goats. Materials used in this study were DNA that originated from 22 Saanen does and its milk protein and milk production recording that was taken at 2,5; 3,0; 3,5 and 4,0 years old of Saanen does. DNA was analyzed using PCR-RFLP method with SacII restriction enzyme to identify genotype of B-LG gene and then were sequenced for each genotype. Sequencing data was analyzed using Clustal W in MEGA7.0, while association of B-LG gene genotype with milk protein and milk production was analyzed using General Linear Model (GLM) in SAS 9.0. The results showed that two alleles (A and G), forming two homozygous genotypes (AA and GG) and one heterozygous genotype (AG) were found, but there were no significant different within genotype on milk protein and milk production. In conclusion, there was no association between β-LG genotype and milk protein and milk production of Saanen goats.
