Abstract

Study on Indigofera arrecta has not been explored widely yet. Therefore, its growth characteristicand its nutritive value need to be studied. The research was conducted to evaluate growth characteristicand its nutritive value of Indigofera arrecta planted on different planting spaces and different levels ofNPK fertilizer dose. Two factors experiments were assigned in a Split-Plot Design. The first factor (A)was planting space, (1) 50x50 cm and (2) 75x75 cm. The Second factor (B) was level of fertilizer dose,(1) 0 kg P2O5/ha+100kg K2O/ha, (2) 100kg P2O5/ha +100kg K2O kg/ha and (3) 200kg P2O5+100kgK2O/ha. The results showed that planting space had no effect on height of plant (P>0.05) but diameter ofstem were statistically different (P<0.05). In addition, their dry matter yield and crude protein contentwere not different (P>0.05) on either planting space or P fertilizer dose. There were no interactionbetween planting space and P fertilizer dose. In addition, there were no effects either planting space or Pfertilizer dose on dry matter edible part, crude protein content, and plant height. Indigofera arrectaplanted on wider planting space produce bigger stem diameter and bigger number of branch.

Abstract

The research aim was to study the variance of some morphometric characteristics and morphologyof Moa buffalo, and the genetic relationships analysis between buffalo subpopulations in Moa Island.Characterization was by using 174 buffalos from any group of ages and sex that were collected fromWest area (Werwaru, Patti), Central area (Syota, Klis) and East area (Tounwawan, Poliwu). Thevariables observed were morphometric characters (body weight, shoulder height, body length, chestwidth, chest depth, chest girth, skull length, skull width, skull height, ear width, ear length, cannon girth,horn length, horn girth and distance between horns), body morphology characters (horn position, headcolor, body color and scheme of body color), and genetic distance between buffalo subpopulations.Body morphometric data were analyzed using mean, standard deviation and variance coefficient. Bodymorphology data were analyzed using relative frequencies. The genetic distance was analyzed usingcanonical discriminant function through Mahalanobis distance approach and by making phylogeny usingUPGMA method. The result indicated that variation of body morphometric was related to productionperformance, variation of color and color scheme of body. Based on genetic distance, central and westsubpopulations were the nearest where West subpopulation was isolated from Central and Eastsubpopulation.

Abstract

The study was aimed to examine the effect of the use of fish fermented by lactic acid bacteria(LAB) as a subtitution for fish meal on serum lipid profile of broiler. One hundred and twenty five dayoldbroiler chicks of CP 707 strains were divided into five groups for five treatments. A CompletelyRandomized Design was used in this experiment. The treatments were 0 (control), 2, 4, 6 and 8% fishfermented by LAB substitution of basal diet containing 8% fish meal. The parameters were blood lipidprofile including total cholesterol, Low Density Lipoprotein (LDL) and High Density Lipoprotein(HDL) cholesterol and triglycerides. Data was analyzed by one-way Analysis of Variance (ANOVA).When the F test indicated a significant effect, the differences between the mean values were analyzed byDuncan’s Multiple Range test. Results showed that using fish silage fermented by LAB on broiler’s feeddid not affect total cholesterol and HDL cholesterol, but significantly affect (p<0.05) levels of LDLcholesterol and serum triglycerides of broilers. Based on serum lipid profile, it could be concluded thatfish fermented by LAB can be used as a substitute for the 100% fish meal in broiler’s feed.

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

The study was carried to identify the phenotypic variation of Alabio duck (Anas platyrhynchosBorneo) being kept by smallholder. This research was conducted in Hulu Sungai Selatan (HSS), HuluSungai Tengah (HST) and Hulu Sungai Utara (HSU), South Kalimantan from May until November2009. Six hundreds (75 males and 525 females) duck characterized in this study was age ranged from5-5.5 months old. The observed parameters were plumage color, color feature, plumage shine, the colorof bill, feet and shank. The results showed that the ducks from three locations (HSS, HST and HSU)performed different plumage color and color feature. The dominant plumage color of the Alabio maleduck was grayish white on the neck (44-56%), grayish black on the back (40-60%) brownish grey onthe chest (52-80%), while the wing was more dominated by blue-green (56%) and black (80%) in thetail. Whereas the female ducks was dominated (70-100%) brown spotted color, the rest blackish gray attail, such as back, neck and chest. Twinkle Alabio duck plumage on males and females have the highestpercentage was the glint of silver (100%) and of shiny blue-green for males (85-100%). The percentageof phenotypic color of bill, feet and shank of male and female ducks were lite yellow (40-60%), brightorange (12-44%), pale yellow (8-28%) and black (4-12%).

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

Morphologically abnormal sperm in semen has been associated with the sub fertility and sterilityfor many years. This study assessed the sperm morphology of Friesian Holstein bull semen which wascollected from three Artificial Insemination centers in Indonesia. Total of 22 bulls were used in thisstudy; an ejaculate from each bull was examined. Three to four glass slides were prepared for each bullsample; a drop of semen was placed on each glass slide, smeared, and air-dried. The smeared sampleswere stained with carbolfuchsin-eosin (Williams stain). Morphological abnormality types were recordedfrom total of 500 spermatozoa. Results demonstrated that all 22 bulls had low sperm abnormality(<10%). Pearshaped was the most frequently type of sperm abnormality found in the samples(0.81±0.93%); while detached head was the lowest (0.01±0.04%).

Abstract

An experiment with 480 day-old chicks of four commercial strains was conducted to study theeffect of genotype on response in body composition to variation in dietary protein: energy ratios. Thechicks were randomly allocated into 4x2x4 factorial and fed on a commercial starter diet (250 g CP and12.5 MJ of ME /kg) from hatching to 5 d of age and divided into two groups with three replicationseach of 16 birds and given either the such starter diet (S) or a finisher diet (F) containing 190 g CP and13.0 MJ of ME /kg. The birds were reared in strain-and sex-intermingled groups in brooders and followoncages until they reached the target body weight of 600-650 g (females) or 650-700 g (males) andtransferred to single cages and fed S or F diet until 1200-1300 g (females) or 1300-1400 g (males). Thelighting program was 23 h light for the first two days, and reduced to 18 h/d for the remainder of theexperiment. There were considerable variations in relative growth performance, FCR, carcass fat andabdominal fat due to genotypes and dietary regimen. Although birds tend to response in similar waywhen dealing with the excesses and insufficient supply, the nutrient requirements in relation to theprotein: energy ratios should be designed according to genetic background.The accumulation of fatduring the growing period was primarily due to the genetic variation whereas beyond this age, variationin abdominal fat was due principally to dietary effects.

Abstract

The productivity of the carabao subsector is influenced by several constraints such as social,technical, economic and policy factors. The need to enhance the local production of carabaos will helplocal farmers to increase their income. Thus, producing thorough breeds of carabaos and improving itgenetically is the best response to these constraints. This study was conducted to present the feasibilitystudy of establishing an Artificial Insemination (AI) Center and its planned area of operation in Brgy.San Juan, Ildefonso, Bulacan. The market, production, organizational and financial viability of operatingthe business would also be evaluated. This particular study will provide insights in establishing an AICenter. Included in this study is the identification of anticipated problems that could affect the businessand recommendation of specific courses of action to counteract these possible problems. Primary datawere obtained through interviews with key informants from the Philippine. Carabao Center (PCC). Togain insights about the present status of an AI Center, interviews with the technicians of PCC and privatefarm were done to get additional information. Secondary data were acquired from various literatures andfrom San Ildefonso Municipal Office. The proposed area would be 1,500 square meters that would beallotted for the laboratory and bullpen. The AI Center will operate six days a week and will be openedfrom 8 AM until 5 PM. However, customers or farmers can call the technicians beyond the office hoursin case of emergency. The total initial investment of Php 3,825,417.39 is needed in establishing the AICenter. The whole amount will be sourced from the owner’s equity. Financial projection showed an IRRof 30% with a computed NPV of Php 2,415,597.00 and a payback period of 3.97 years. Based on all themarket, technical, organizational, financial factors, projections and data analysis, it is said that thisbusiness endeavor is viable and feasible.
