Identification of genes in rabbits correlated to economic traits were intended to improve and develop their genetic quality. The objective of this research was to analyze the variability of growth hormone gene (GH) in three rabbit breeds, i.e. Rex, Satin, and Reza (Rex and Satin crosses) then was associated with ultrasound imaging of Longissimus dorsi muscle and perirenal fat thickness. Identification of the variability of growth hormone gene was analyzed using PCR RFLP technique from blood samples of 33 mature male rabbits in Indonesian Research Institute for Animal Production (IRIAP). Thickness of Longissimus dorsi muscle and perirenal fat were imaged and measured by using ultrasound unit at 2nd to 3rd lumbar vertebrae in the left body side. PCR product of GH gene fragment (231 base pair /bp) was digested with restriction enzyme Bsh1236I. PCR-RFLP patterns were allele T resulted in an undigested fragment of 231 bp; allele C resulted in fragment of 169 bp and 62 bp. The result showed that Bsh1236I GH gene had three genotypes, i.e. CC, TT, and CT. There were signifficant association of Longissimus dorsi muscle thickness between rabbit breed (P<0.05). There was no significant association between GH Bsh1236I gene polymorphism and imaging ultrasound of Longissimus dorsi muscle and perirenal fat thickness. The association of characteristic genotype of GH|Bsh1236Igene with measurement phenotype was not significant, however it had potency as marker assisted selection (MAS). Key words: growth hormone gene, Longissimus dorsi, perirenal fat, rabbit, ultrasound

The aim of this study was to estimate genetic and phenotypic parameters of growth traits consisting of birth weight (BW), weaning weight (WW), 6 mo body weight (6WM), 12 mo body weight (12WM), and 18 mo body weight (18WM) of Ettawa Grade goats. The number of goat used to determine growth traits of BW, WW, 6WM, 12WM, and 18WM were 316; 316; 259; 259 and 165 heads, respectively. Data were analyzed using General Linear Model (GLM) to identify non-genetic effect. Estimation of genetic and phenotypic parameters including heritability, repeatability, genetic and phenotypic correlation were calculated using Restricted Maximum Likelihood and GLM. Genetic trends were calculated using the regression of mean breeding values on birth year. The results showed that parity and type of birth had significant (P<0.05) influence on all growth traits. Estimated heritability of birth, weaning, 6WM, 12WM, and 18WM were 0.54±0.12; 0.35±0.07; 0.37±0.09; 0.68±0.16 and 0.63±0.19, respectively. Estimated repeatability of WW, 6WM, 12WM and 18WM, WW, 6WM, 12WM and 18WM were 0.98±0.01; 0.97±0.01; 0.94±0.03; 0.71±0.12 and 0.91±0.04, respectively. The genetic trends for traits of BW and 18MW were decreased fluctuatively. However, the WW, 6MW, 12MW were increased fluctuatively. The high and positive genetic correlations between all growth traits and 12WM traits in this study indicated that selection for high 12WM will improve genetic merit in Ettawa Grade goats. Key words: body weight, EBV, Ettawa Grade goat, genetic and phenotypic parameters

The objectives of this research were to: 1) design the stocking density of broiler reared at a closed house system in wet tropical climates based on the heat released by broiler, 2) design broiler harvesting system based on the housing heat load, and 3) design required housing area based on the broiler age. The housing design used to determine the broiler stocking density was based on Computational Fluid Dynamics (CFD) with Solid Works Flow Simulation software. The method had good validation shown by small number of average percentage of deviation (6.07%). Simulation was carried out by changing the number of broilers i.e. 16, 18, 20, 21 and 22 birds/m2. According to the CFD simulation result, total heat load inside the house was 233.33 kW at 21 birds/m2 at weight 1.65 kg/bird. At that stocking density the housing can be occupied by 27,224 birds until 22 days of age. The highest total weight was produced by daily harvesting started from 22 to 32 d. It can be concluded that the stocking density of closed house for broiler is 34.65 kg/m2, total production is 45,717 kg per period and the required area for 27,224 broilers is 248.63 m2 (1 to 7 days of age broiler), 562.52 m2 (8 to 14 days of age broiler) and 1,000 m2 (15 to 22 days of age broiler). Key words: broiler, computational fluid dynamics, stocking density, total heat

The research was aimed to investigate the influence of minimizing chromium use on combined chromium-gambier process upon the characteristics of tanned leather. At the first stage of tanning process, chromium was used and in the second stage it was replaced by gambier. The raw material used was dried saline-preserved goat skin. The treatments applied on the tanning process were the different concentrations of chromium ranging from the highest level of 6% to the lowest level of 1% which was then re-tanned by using 8% concentration of gambier. The examination parameters included chemical and physical properties as well as visual investigation on the tanned leather in accordance with SNI-06-0463-1989-A. The result showed that the tanning process by using 2% chromium in the first step and 8% gambier in the second step was a treatment combination producing tanned leather that met the standard. The examination on tanned leather resulted from such treatment showed 56.33% rawhide, 17.45% of bound tannin, 31.22% of tanning level, tensile strength 386.30 kg/cm2, flexibility 31.91%, leather width 1.3 mm, density 0.75 g/cm3, the leather was quite elastic with light brownish color. In conclusion, minimizing the use of chromium in the combined tanning process of chromium and gambier can be implemented to the lowest of 2% chromium concentration and 8% gambier in the first and second step, respectively. Key words: gambier, leather, minimizing chromium, tanning

Publisher : Faculty of Animal Science, Bogor Agricultural University

This research aimed to study the carcass characteristics of Kacang goats fed ration containing kapok seed meal (KSM) as a component of the concentrate. The experiment was conducted in two stages. The first stage was to find out the best variety of kapok that will be used in the second experiment; the second stage was to determine the benefits of KSM on carcass characteristics. Twenty-five, 8 months old Kacang goats with initial body weight of 11.71±1.08 kg, were used in this experiment. The animals were housed individually based on completely randomized design (CRD) with 5 treatments and 5 replications. The rations were based on forage:concentrate ratio of 50:50 dry matter basis. The ration contained concentrates, with increasing levels of KSM, i.e.: R0 (napier grass + concentrate: rice bran, coconut cake, corn, urea + 0% KSM); R5 (R0 + KSM 5%); R10 (R0 + KSM 10%); R15 (R0 + KSM 15%); and R20 (R0 + KSM 20%). Drinking water was provided ad libitum. The result of first stage showed that KSM variety of MH-1 would be used as a component of the concentrate on the second experiment. The increasing level of KSM in the rations had significant effect (P<0.05) on physical characteristics of the carcass, such as dressing percentage (44.35%), carcass length (54.006 cm), fleshing index (130.59 g/cm), plumpness of leg (87.48%), loin eye area (5.06 cm2), and percentage of carcass meat (64.69%). It is concluded that MH-1 variety of KSM can be used as a feed component up to 20 % in the goat ration. Key words: carcass characteristics, Kacang goat, kapok seed meal (KSM)

The main objective of this study was to compare the effects of different plantain ash sources (plantain root base ash (PRA) and plantain stalk ash (PSA) supplementation on the performance of pullets fed commercial diets. Ninety six Isa brown pullets aged 15 weeks were therefore used to assess the effect of supplementing commercial diets with plantain root base (PRA) and stalk ashes (PSA) on growth performance, carcass and organ characteristics of pullets during 4 weeks before point of laying (19 weeks of age) and 6 weeks of laying period (25 weeks of age). The pullets were divided into two groups of 48 each for supplementation with either PSA or PRA. Each group was divided into four groups of 12, which were further replicated 3 times with 4 birds per replicate in a completely randomized design. At each developmental stage, the feed offered to the birds was supplemented with 0 (control), 1, 2, and 3 g/kg body weight of PSA or PRA. One g/kgBW of PRA supplementation elicited observable growth performance effects on the birds, while for PSA it was 2 g/kgBW. The 2 g/kgBW PSA supplemented birds gained significantly (P<0.05) more weight than the other groups except the control, which consumed significantly (P<0.05) more feed. At point of laying, the 1g/kgBW PRA group recorded significantly (P<0.05) higher body weight and weight gain than the control. Plantain root base ash affected dressing percentage significantly (P<0.05) resulting in higher thigh weights, while organ weights decreased with increasing ash supplementation levels. Plantain ash therefore has positive effect on growth and edible carcass cut. Key words: plantain ash, pullets, feed, carcass

Forages in swamp area consist of grass and legumes that have good productivity and nutrient quality. This research was aimed to evaluate the potency of swamp forage on digestibility and performance of goats. There were 24 local male goats aged 10-12 months with initial body weight of 13.10±1.55 kg, allocated into 6 treatments. Those were control (R0): 60% grass and 40% legumes; (R1): 60% swamp forages and 40% concentrate; (R2): 100% swamp forages; (R3): 100% swamp forage hay; (R4): 100% swamp forage silage; (R5): 100% haylage swamp forages. Results showed that silage treatment significantly increased (P<0.05) consumption and digestibility. Swamp forages could be utilized well by preservation (silage, hay, and haylage). Ensilage of swamp forages increased protein content from 13.72% to 14.02%, protein intake (74.62 g/d), dry matter intake (532.11 g/d), nitrogen free extract intake (257.39 g/d), with total body weight gain (3.5 kg) in eight weeks and average daily gain (62.60 g/d). It is concluded that ensilage of swamp forages (R4) is very potential to be utilized as forage source for ruminants such as goats. Key words: body weight, goat, haylage, silage, swamp forage

The objective of the study was to investigate broiler immune responses during the starter phase to graded levels of digestible lysine. This experiment used 175 mixed sex broiler chickens from 1 to 21 days of age. Seven chicks were selected and allocated to each floor pens. Chicks were fed experimental diets from one day old to 21 days of age. Dietary treatments included the following levels of digestible lysine: 6.0, 8.0, 10.0, 12.0 and 14.0 g/kg diet. Supplemental synthetic L-Lysine-HCl which was considered to be 100% digestible was added to diets to obtain the concentration of the digestible amino acid. At 21 days of age, two chickens from each pen with body weights close to the pen mean were selected for evaluation of immunological variables. Immune organs (spleen and bursa), cellular immune response (skin test), and antibody production against infectious bronchitis virus (IBV) were determined. Blood samples (plasma) were taken from the same birds to determine antibody titer against IBV. The birds were euthanized, and immune organs (spleen and bursa) were removed, and weighed individually. The results showed that spleen and bursa weight of birds fed diet containing 6.0 g/kg digestible lysine was significantly lower than those given diet containing 10 to 14 g/kg of digestible lysine. Toe web thickness of chickens fed diet containing 6.0 g/kg digestible lysine was significantly lower than the birds fed diets containing 14 g/kg digestible lysine. In conclusion, diet containing 8.0 g/kg appeared to have greatest potential to modulate immune response among other levels. However increasing levels of lysine did not have significant effect on antibody production. Key words: amino acid, lysine, broiler, digestible

Publisher : Faculty of Animal Science, Bogor Agricultural University

Iran together with Afghanistan is the third largest producer and exporter of cashmere in the world, after China and Mongolia. This paper assesses the status of cashmere marketing of Iran in order to evaluate sustainability, and to identify some constraints limiting the productivity and compa-tibility. In August to December 2011 structured questionnaires and interviews were used to compile information regarding market chains cashmere industry of Iran. Information compiled revealed that nearly all the cashmere was marketed by direct buying in Iran. The principle centers for the gathering and rough sorting raw cashmere in Iran were Baft, Sirjan, Mashad, and Birjand. The principle cashmere-importing countries of Iranian cashmere were China, England, Belgium and Italy. The price for Iranian cashmere has showed large fluctuations in the last forty years: it increased from 25 dollars in 1972 to 110 dollars in 1988 and decreased to 65 dollars in 2006 and again increased to 110 dollars in 2012. Given the present status of production and marketing there seems to be substantial scope to improve the value addition of Iranian cashmere. Key words: cashmere, production, marketing, export, value addition
