Abstract

The objective of this research was to study the nutrient digestibility and the metabolizable energyvalue of the waste of saccharification process from cassava bagasse (WSPCB) on the laying hens.Twenty ISA-Brown laying hens at the age of 72 weeks were randomly distributed into three feedingtreatments which consisted of cassava bagase (CB), WSPCB of solid state fermentation method(WSPCB-SSF), and WSPCB of sub merged fermentation method (WSPCB-SmF). All of the hens werefasted for 24 hours and 15 of them were fed with CB, WSPCB-SSF and WSPCB-SmF (five hens foreach test-diet). The other five hens were still fasted. Then, all of the hens were fasted again and theirexcreta were collected during 48 hours. The nutrient digestibilities which were measured consisted ofthe Apparent and True Digestibility of Dry matter (ADDM and TDDM), Crude Fiber (ADCF andTDCF), Starch (ADS and TDS), and the Apparent and True Metabolizable Energy (AME and TME).The result of this research showed that the saccharification process generated the solid waste with thenutrient digestibility value (ADDM, TDDM, ADS, TDS, AME, and TME) which were significantlylower (P<0.05) than those of CB. The crude fiber digestibility value of the WSPCB has an opositephenomenon in which the ADCF and TDCF of WSPCB-SmF were greater than CB. In conclusion, thenutrient digestibility value, except for ADCF and TDCF, of the WSPCB on the laying hens were lowerin value than those CB.

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.

Abstract

This research is aimed to evaluate the nonlinear mathematical model in predicting the age and weight of Kebumen Ongole Grade (PO) cattle at puberty. The data used in this research was weight recordings of (768) PO cattle, ranging from calf (< 1 month) to adult (60 months), collected by Kebumen PO cattle Breeder Association (ASPOKEB) from 2013 to 2015. These cattle were reared by a group of farmers located in six sub-districts: Mirit, Lembu Purwo, Ambal, Puring, Petanahan, and Klirong in Kebumen district, Jawa Tengah Province. Brody, Bertalanfy, Logistic and Gompertz mathematical models were used to analyze the data. The analysis showed that the R2of the four models classify high in the category (R2 >0.70). Mature weight (A) of PO cattle predicted by Logistic (349 kg) and Gompertz (358 kg) were most appropriate. Out of the four models, the Logistic model was the most accurate in predicting the weight at puberty (174 kg) of PO cattle, but all observed cattle are still in the follicular phase.

Abstract

The PUFA (polyunsaturated fatty acid)-concentrates containing fatty acid sources (roasted corn grain,roasted soy bean meal, and corn oil) was designated as PUFA- concentrate for dairy goat. There werefour PUFA-concentrates, no supplement (PC0), 0.5% or 5 g yeast (PCY), 2% or 20 g curcuma powder(PCC), and 0.5% or 5g yeast with 2% or 20g curcuma powder (PCM). These PUFA-concentrates wereevaluated for nutrients and fatty acid contents during 2, 4, and 6 weeks of storage. The application oftreatments utilized in this research was completely randomized design with repeated measurement andsplit plot statistical analysis. Results showed that the contents of dry matter, organic matter, ether extract,crude protein, N-free extract, gross energy, acid detergent fiber, Ca, P, and Saccharomyces cereviseaewere significantly (P<0.05) remained stable as caused by unchained moisture of PUFA-concentrate withcombined supplements (Y5C20) in the 6 weeks of storage. The total PUFA (P), P/S, monounsaturatedfatty acid (MUFA), and long chained fatty acid contents tended to be high in PUFA-concentrate with 2%or 20 g curcuma powder. Whereas, the PUFA-concentrate with a combination of 0.5% or 5 g yeast and2% or 20 g curcuma powder was higher in unsaturated (U) fat and the ratio of U/S. In conclusion, combining all nutrient performances during the storage of 2 to 6 weeks, the PUFA-concentrate with0.5% or 5 g yeast and 2% or 20 g curcuma powder was considered nutritionally good.

Abstract

Each four young bulls of Madura cattle and Ongole Crossbred (OC) cattle were used to study theefficiency of ruminal fermentation by comparing the proportion of Volatile Fatty Acid (VFA) of thesetwo breeds which were raised under intensive feeding. All the cattle were in about 1.5 years-old with anaverage body weight of 147.75 ± 14.57 kg and 167 ± 22.57 kg, for Madura and OC cattle, respectively.They were fed Napier grass (Pennisetum purpureum) hay, and concentrate feeding consists of pollard,soybean meal and rice bran for 10 weeks. Parameters measured were concentration of VFA at 0, 3 and 6h post-feeding and pH. The concentration of VFA in both Madura and OC cattle was peaked at 3 h postfeeding,being 136.1 mmol and 158.9 mmol, respectively, and then were decreased at 6 h post-feeding ata level of 58.1 and 98.2 mmol, respectively. The proportion of acetic acid in Madura and OC cattle were53.33% and 52.0% of total VFA, respectively, while the proportion of propionic acid and butyric acidwere 28.80% and 17.87% for Madura cattle, and 30.71% and 17.28% for OC cattle, respectively. Inaddition, the Acetic/Propionic ratios were 1.85 and 1.69 for Madura and OC cattle, respectively. RumenpH conditions of both cattle breeds tended to be basic, i.e. Madura cattle was ranged at 8.0-8.4, while thePO cattle was ranged at 7.6-8.4. In conclusion, both cattle breeds (Madura and OC cattle) have a similarefficiency to utilize the feeds in the rumen.

Abstract

The study investigated the influence of dietary incorporation of formic acid, butyric acid or their blends on growth rate, haematological indices and intestinal morphometric of broilers. A number of 240 Lohmann MB-202 chicks were pass rounded to four dietary groups, including CONT (chicks taking in basal feed with no additive), BTRT (chicks receiving basal feed with 0.03% butyric acid), FRMT (chicks receiving basal feed with 0.1% formic acid) and BTRT+FRMT (chicks receiving basal feed containing 0.03% butyric acid and 0.1% formic acid). Weight of chicks and intake were measured every week, while blood sample was collected at day 21 and 35. At day 35, birds were slaughtered and small intestinal segments and digesta were collected. At day 21, body weight was bigger (P<0.05) in BTRT+FRMT than in other birds. Feeding the blends of formic and butyric acids resulted in higher (P<0.05) value of mean corpuscular haemoglobin concentration (MCHC) at day 21. Feeding organic acids was associated with the lower (P<0.05) proportion of thrombocytes in broilers at day 35. Supplementation of butyric acid resulted in higher (P<0.05) serum albumin concentration at day 35. Butyric acid produced higher (P<0.05) levels of triglyceride as well as low-density lipoprotein (LDL) in the serum. The mixture of formic and butyric acids resulted in higher (P<0.05) titer of antibody against Newcastle disease vaccine (NDV) at day 21. Feeding formic acid decreased (P<0.05) ileal population of lactose negative enterobacteria at day 35. Overall, dietary supplementation of the blends of formic and butyric acids resulted in improved growth and immune defence of broiler chicks.

Abstract

Kappa-casein (κ-casein) gene is known as a gene that plays a role in controlling milk protein andalso play a crucial role in the coagulation and curdling of milk. This study was aimed to identifypolymorphisms of the κ-Casein gene of local buffaloes in Indonesia. A total number of 40 heads ofriverine buffalo and 250 heads of swamp buffalo. This study used PCR-RFLP method, whichamplification of the κ-Casein gene resulted an amplicon with length of 157 bp, located in exon 4. Theamplified fragment were digested with EcoRV restriction enzyme, which cut the κ-Casein gene in exon4 at nucleotides of GAT|ATC, revealed the presence of one polymorphism at the base position of 23 bpthat occurs with a substitution of Ile (ATC) of the T genetic variant into Thr (ACC) of the C geneticvariant. Genotyping κ-Casein gene in riverine buffalo produced two types of allele, namely C allele (157bp) and T allele (136 and 21 bp). These two alleles resulted in three types of genotypes, namely CC, CT,and TT. Frequency of the C allele was dominant to T allele. κ-Casein gene in swamp buffalo wasmonomorphic with one allele, namely C allele. Heterozygosity value of riverine and swamp buffaloeswere low. PIC value in riverine and swamp buffalo ranged 0.000-0.288. Fixation index of κ-Casein genein riverine buffalo was low (Siborong-borong SBBC = -0,0036; Deli Serdang = -0.025), but in swampbuffalo was in fixation. This study showed that κ-Casein|EcoRV were polymorphic in riverine buffaloand monomorphic in swamp buffalo.

Abstract

The objective of this study was to determine leucocyte and offspring production of guinea pig (Cavia cobaya) giving Anredera cordifolia leaf extract. Materials used were female 16 heads of guinea pig with body weight of 425g. The treatments were an extract of A. cordifolia leaf at doses of 0, 10, 50 and 90 mg/head, designated as T0, T1, T2 and T3, respectively. A. cordifolia leaf extract was administered orally from 10 days prepartum to 10 days postpartum. Blood was taken at 10 days prepartum and 10 days postpartum. Total birth of the offspring was observed. Data were analyzed by analysis of variance and if there was effect of treatment, then continued with Duncan multiple range test and Chi-Square test for fetal production between the given A. cordifolia leaf extract and control. The result showed that there was no significant difference for 10 days prepartum after addition of A cordifolia leaf extract treatment. The postpartum treated showed a total 50 mg/head level increaed for monocytes than that of level 0, 10 and 90 mg/head. Ten days postpartum treatment showed the total increase for leucocyte and monocytes total were 50 and 90 mg/head, respectively compared to 10 mg/head level. Total lymphocyte of 90 mg/head increased compared to level 10 and 50 mg/head. The highest total neutrophil as found at level of 50 mg/head which increased compared to the level of 0 and 10 mg/head. ProvisioningA. cordifolialeaf extract at doses level of 50 and 90 mg/head could increase litter size (P<0.05; χ2=9.267) and decreased offspring mortality (P<0.05; χ2=6.4). In conclusion, by giving 50 mg/head A. cordifolia leaf extract could increase leucocyte profile and offspring production of guinea pig.

Abstract

The aim of the research was to determine the associations between polymorphism of the bovine growth hormone (GH) gene (Leu/Val) and milk production of Friesian Holstein Cattle. A total of 62 cows which consist of two Friesian Holstein cattle groups (from New Zealand=19 heads and Australia=43 heads) were used for the research. We performed the Polymerase Chain Reaction and followed by Restriction Fragment Length Polymorphism using AluI restriction enzyme. The genotype was observed base on the target gene GH 211 bp in the part of intron 4 and exon 5 of growth hormone gene. The frequencies of genotypes LL were found higher than genotype LV in both groups. Friesian Holstein cattle from New Zealand showed the genotype LL and LV as 84% and 16%, respectively. Friesian Holstein cattle from Australia show the genotype LL and LV as 79% and 21%, respectively. The association between Leu/Val polymorphism on milk production, fat and protein content in both groups did not show the significant effect. Base on two groups of the origin of cattle, the result showed the significant different on fat and protein content of milk. Fat and protein contents of milk were higher in breed of FH imported from Australia compared to those in breed of FH imported from New Zailand.

Abstract

The purpose of this research was to analyze factors influencing farmers' decision to increasebeef cattle business scale through improved technology. The research was conducted by using a surveymethod. Five districts were purposively selected in three base areas and two non-base areas of beefcattle in Central Java Province, Indonesia. Twenty beef cattle groups were selected based on the largestcattle population managed and their performance, while 196 respondents were randomly selected.Farmers’ decision to increase beef cattle business scale was determined using a probit model. Result ofthe research indicated that the number of family labor and expectation to increase income had asignificantly positive influence on the farmers’ decision to increase beef cattle business scale. It meantthat if the total number of family labor increased, so did the farmers’ decision to increase the beef cattlebusiness scale. Also, if the expectation to revenue increased, so did the farmers’ decision to increase thebeef cattle business scale. On the contrary, education level and business risk had negative significantinfluence on the farmers’ decision to increase the beef cattle business scale with the significance levelsof 1.1 and 0.84, respectively.
