Abstract

The objective of this study was to evaluate the effectiveness usage of Indigofera zollingeriana leaf meal (I) and Sardinella lemuru fish oil (L) in diets on the decreasing levels of cholesterol and lipid metabolism of laying duck. One hundred and forty-four Magelang ducks aged 20-32 weeks, laying periode, with an average body weigth of 1,72±0,12 kg were used, which were divided into 6 groups of experimental diets, 3 replications, and of 8 layers each. A completely randomized design, 3x2 factorial design was used in this experiment. The first factor was usage Indigofera zollingeriana leaf meal which replaced protein soybean meal (0%, 5,5%, 11%). The second factor was usage Sardinella lemuru fish oil (0%, 2%). The results showed that the treatment (I5.5L2) was highly significant affected (P<0.01) the level of triglyceride, HDL, and LDL in the blood. The treatment I0L2 significantly decrease (P<0.05) total cholesterol of blood lipid profile and meat cholesterol. The treatment (I11L2) was highly significantly decreased (P<0.01) egg cholesterol. The conclusion of this study was that feeding Indigofera zollingeriana leaf meal 5.5% and Sardinella lemuru fish oil 2% in laying duck’s diet could maintain the balance of blood lipid profiles by lowering plasma triglycerides, LDL, cholesterol and raising up plasma HDL and plays an important role on lipid metabolism of Magelang laying ducks to produce eggs and meat with low cholesterol content.

Abstract

The experiment was conducted to evaluate the effect of fermented cacao shell on the carcassquality, percentage of non carcass components, marbling and cholesterol content of Bali cattle. NineBali cattle of 1.5-2 year old and 165-175 kg weight were grouped into three feeding trials. The firstgroup P0 was fed ration containing 30% cacao shell fermented with its own microorganism and 70%corn straw, the second group P1 was fed ration containing 30% cacao shell fermented with ruminal fluidand 70% corn straw, and the third group P2 was fed ration containing 30% cacao shell fermented withBioplus and 70% corn straw. All cattle were also given commercial concentrate amounting to 1% oftheir bodyweight. The cattle were slaughtered at the end of feeding trial and their carcasses, meat andnon carcass components were analysed. Experimental design used was completely randomized design.The results showed that carcass percentage, back fat thickness, rib eye area and meat index of Bali cattle were as follows group PO 53.33%, 3.08 mm, 59.65 cm2, 0.79%; group P1 52.64%, 5.31 mm, 58.52 cm,0.82% and group P2 5.32%, 5.7 mm, 57.75 cm, 0.79%, respectively. The marbling and cholesterolcontent of Bali beef were group PO 2.65% and 71.25 mg/100g, group P1 2.12% and 48.75 mg/100g,and P2 2.63% and 74.50 mg/100g. It could be concluded that fermented cacao shell could be used asfeed ingredient without any effect on the carcass and meat quality, marbling and cholesterol contents ofmale Bali beef.

Abstract

The main objective of this research is to present an alternative approach to meet beef selfsufficiencyin West Papua, Indonesia. It mainly focuses on calculating the needed number of productivecows to enhance beef production in the province. Out of the total farmer households in Manokwari,Indonesia, 189 farmer-respondents were selected as samples of the study. Selection of the sample wasbased on the number of cattle kept in every age group (less than one (<1) year old; one to two (1-2)years old, and more than two (>2) years old and the number of productive cows. Secondary data camefrom the time series data of the number of slaughtered cattle vis-à-vis the population of all districts inWest Papua Province from 1980-2008. Data were analyzed using the Partial Adjustment Model (PAM)and Ordinary Least Square (OLS) method. Results of the study showed that beef self-sufficiency in WestPapua depend on the availability of the number of productive cows to produce ready-slaughtered-bull inthe previous year. Particularly for West Papua, to produce one unit of bull in the tth –year, with theassumption that cattle mortality is 4.92%, a number of 2.38 animal units AU of productive cows must beprovided in the previous two (2) years.

Abstract

Birth weight and calving interval are included of productivity traits that can be increased by selection program. However, the standard of desirable birth weight in cattle during the selection program is important to prevent dystocia incident risk. This study was aimed to select Bali cattle (Bos javanicus) based on Estimated Breeding Value of birth weight (EBVBW) and Most Probable Producing Ability of birth weight (MPPABW) and calving interval (MPPACI). Total of 758 records data of BW were collected from Lombok and Sumbawa islands, West Nusa Tenggara Province. Research showed the average of BW in Bali calves were 15.69±1.70 kg (Lombok) and 13.49±1.89 (Sumbawa). The average of CI in Bali cows at both islands were about 385 days. In addition, the heritability (h2) values of BW in both islands was about 0.90. The repeatability (r) values of BW in both islands were about 0.30. Meanwhile, the r value of CI in Sumbawa island was 0.39. The highest of EBVBW for sire was +4.25 kg by bull’s ID: 0838 (Sumbawa). Meanwhile, the highest of EBVBW for calves was +6.07 kg by calf’s ID: 0917 (Sumbawa). The highest of MPPABW was +2.67 kg by cow’s ID: 0872 (Sumbawa). The lowest of MPPACI was -25.70 days by cow’s ID: 02076 (Lombok).

Abstract

An experiment was conducted to observe the effect of non-starch polysaccharides (NSP) onperformance and digestive activity of laying hens. Thirty-two ISA Brown hens were individually cagedand offered four diets (wheat-based, millrun-based, barley-based, and barley-enzymes diets) for 10weeks. The present experiment was assigned in a completely randomized design with 8 replicates perdietary treatment. Wheat- and barley diets caused significantly higher (P<0.05) viscosity than otherdiets. Increased viscosity caused lower digesta dry matter (DM) (P<0.01) and higher excreta moisture(P<0.05). The wheat diet did not cause a negative effect on intestinal starch digestibility, feed intake, andbird performance (P>0.05). Birds fed the barley-based diet had lower weight gain (P<0.05) and highercaecal weight (P<0.05) than those given other diets. Enzyme supplementation on barley dietssignificantly (P<0.05) reduced jejunal digesta viscosity and caecal weight, increased weight gain(P<0.05) and ileal digesta DM (P<0.01), and numerically reduced excreta moisture. The current studydemonstrated that NSP have a profound effect on digesta viscosity, performance, and digestive organs ofbirds; however, the NSP action may be modified by an interaction with each other and with other cellwallcomponents of grains in the gut. Enzyme supplementation reduced the negative effect of digestaviscosity.

Abstract

Growth hormone gene that controls metabolism and body size of animals and polymorphism of the gene is known related to performance of livestock. Identification of gene polymorphisms was important to get early information to determine genetic markers associated with economically desirable traits. Genetic mapping is one of important characterizations in the selection process. Pesisir cattle is one of local cattle in Indonesia that are reared in West Sumatera and have become adaptive to local environment. The present study aimed to identify the genotype of Growth Hormone gene (GH891│MspI) of the Pesisir cattle and crossbred Simmental-Pesisir cattle (designated as SimPes) and relationship between growth performance (body weight and body size). The present study was conducted to 30 blood samples consisted of 15 Pesisir cattle and 15 SimPes cattle. Body weight and body size were measured at 12-18 months of age. The Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method was used in this research. The results showed that there exist three variant genotypes (MspI-/-, MspI+/-, MspI+/+) and that allele frequencies of MspI- and MspI+ were 53.3% and 46.7%, respectively. Non-significant effect has found between GH’s genotype and growth traits (Body measurement and body weight) in both of breed cattle. In conclusion, three variant genotypes (GH891│MspI) in Pesisir and SimPes (Simmental x Pesisir) cattle population were found and no significant effect on growth trait performance.

Abstract

This study was conducted to determine the effect of crude palm oil (CPO) protected byformaldehyde on chemical and physical quality of lamb. The research design applied was completelyrandomized design with 3 treatments and 5 replications Fifteen local male sheeps aged 9-12 monthsweighing 14-17 kg were divided into 3 groups for different ration treatments. The first group receivedonly basal ration (R0), the 2nd group received basal ration and 3% of CPO (R1), while the 3rd groupreceived basal ration and 3% of CPO protected by 2% of formaldehyde (R2). The data were analyzed byanalysis of variance. The differences among treatments were tested by Duncan’s New Multiple RangeTest. The results showed that the addition of CPO protected by formaldehyde (R2) in the sheep dietincreased lamb protein and fat content (P<0.05), produced tenderer lamb (P<0.01) with lower cookingloss (P<0.01). The diet with CPO protected by formaldehyde can improve the chemical and physicalquality of meat sheeps.

Abstract

Twenty sows housed indoors in individual stalls were used to determine the relationships betweenatmospheric ammonia exposure and microclimate on olfactory metabolic and sows RNAreticulocyt, and toknow the prediction models of the olfactory metabolic and sows RNAreticulocyt by measurement ofatmospheric ammonia exposure and microclimate level. Result indicated a significantly negative effectof ammonia on commonly olfactory metabolic parameters and %RNAreticulocyt. The results also showedthat ammonia has been reduced the function of olfactory receptors and activities of Ca2+-gated chloridechannel open and efflux of Cl- to depolarize cell, as soon as reducing an electrical signal to the brain, sogives impact to blood metabolism (especially RNAreticulocyt). Simultaneous effect between ammonia andhumidity proved to be a good indicator for predicting model of olfactory metabolic, and %RNAreticulocytespecially for creatine kinase (=16.65+0.02H-0.59A), glucose (=21.55-0.10H-0.01A), lactate (=8,87-0.03H-0.20A), ATPase (=0.05+0.00H-0.02A), adenosine triphosphate (ATP) (=13.19-0.19H+0.86A).

Abstract

An experiment was conducted to determine the effect of different insoluble non-starchpolysaccharides (NSP) sources supplementation at levels 0, 20, 40, 60 g/kg on performance anddigestive tract development of young broilers (doc-21 d). Results showed that there were no interactionsbetween insoluble NSP sources and levels at any variable measured. Only levels of insoluble NSP hadsignificant effect. Young broilers fed mash basal diet supplemented with 6% insoluble NSP decreasedbody weight gain (P<0.05) and impaired gain-to-feed ratio (P<0.01). Diets did not have a significanteffect on feed intake (FI), in addition to the relative weight of gizzard, jejunum-ileum, caeca, andpancreas. Levels of NSP affected the weight of gastrointestinal digesta with jejunal-ileal digesta wasfound to be the highest (P<0.01) in 6% insoluble NSP supplementation. Dry matter of jejunal-ilealdigesta and excreta moisture also did not significantly affected by diets (P≥0.05). The present studydemonstrated that the insoluble NSP can be supplemented to young broilers diet up to 4%. It is likelythat increased performance of young broilers supplemented with insoluble NSP up to 4% was due toincrease FI and a better gut environment. The supplementation of insoluble NSP did not produce strongimpact considering that the diets were given in mash form.
