Abstract

The effect of waru leaf (Hibiscus tiliaceus) supplementation as saponin source on ruminalfermentation characteristics were studied using in vitro gas production techniques. Rumen fluid wastaken from fistulated Ongole crossbreed cattle. The treatments consisted of control treatments (Napiergrass with monensin and Napier grass without waru leaf (0% saponin level) and waru leafsupplementation treatments as much as 11, 22, 33, and 44 mg of feed (in dry matter basis) or equal to 5,10, 15, and 20% saponin level added to feed substrate of Napier grass (Pennisetum purpureum). Theresult showed that protozoa numbers and total gas production were significantly reduced (P<0.05) inline with the increasing of saponin level compared to 0% saponin level, while NH3, VFA concentrationand pH after 48 h fermentation were not affected by the treatment. VFA concentration increased by waruleaf up to 10% saponin level then decreased at level 15 and 20%. Ratio of acetate to propionate (A/P)and non glucogenic ratio (NGR) decreased at 5, 10, and 15% saponin level, but increased at level 20%.It could be concluded that waru leaf supplementation at 10% saponin level of feed was the optimumlevel which gave positive effect on rumen feed fermentation.

Abstract

The purposes of this study were to investigate the effect of administration of GnRH and PGF2α ononset of estrus and conception rate in different postpartum swamp buffalo (Bubalus bubalis). Twentypostpartum (pp) buffalo-cows were divided into four groups of five buffaloes as follows: Group A (30day pp), Group B (45 dpp), Group C (60 dpp), and Group D (75 dpp). The buffaloes in each group wereinjected intramuscularly with 3 ml GnRH at day 0, followed by intramuscular injection of 2.5 ml PGF2α,10 ml) at day 7 after GnRH injection. Observation of estrus was performed 24 h after injection of PGF2α.Artificial insemination was performed 18 h after estrus signs clearly visible. The result of study showedthat there were no difference (p>0.05) among treatments on the percentages of estrus (100%), onset ofestrus (37.4 to 38.4 h), duration of estrus (16.8 to 18.2 h) and conception rate (100%). In conclusion,buffalo-cows in Kampar Regency can be served as early as 30 days post partum using combination of 3ml GnRH and 2.5 ml of PGF2α.

Abstract

An experiment was conducted to observe the effect of dietary fiber given in mash form onperformance and cannibalism mortality in laying hens. Three different diets: a wheat-based diet, a guargum diet (a wheat-based diet + 20 g/kg guar gum) and a lucerne meal diet (a wheat-based diet + 40 g/kglucerne meal) in mash form were offered for 12 weeks. The results showed that birds fed guar gum diethad the lowest intake (p<0.01), egg weight (p<0.05), body weight (p<0.05) and the lowest eggproduction (p<0.01) compared to those fed other diets. Diets did not have a significant effect (p>0.05)on feed to egg ratio and cannibalism mortality, but numerically the birds fed the guar gum diet had thehighest mortality (11.3%) and the lucerne diet had the lowest (6.9%). The lack of profound differenceswas probably due to the diets were given in mash form. In conclusion, diets containing high soluble NSPreduced the performance and increased the mortality due to cannibalism in laying hens. The use of mashform may have a potential in reducing the negative effect of soluble NSP on cannibalism.

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

A study of effect of inclusion of calcium-palm fatty acid (Ca-PFA) in the diets on growthperformance and profile of body fatty acid has been conducted for 4 weeks in broiler. A total of 160birds were used in present experiment which was arranged in a Completely Randomized Design with 4treatments and 5 replications (8 birds each). Dietary inclusions of Ca-PFA of 0, 5, 10 and 15% werereflected as R0, R1, R2 and R3, respectively. Results of the experiment showed that growth performancebased on the feed consumption significantly decreased (p<0.05), but there were no significant (p>0.05)effect for final body weight, carcass percentage and carcass composition. The inclusion of Ca-PFA in thediet was not affected the saturated fatty acid (p>0.05), but showed significant effect on unsaturated fattyacid and omega-3 fatty acid (p<0.05). Body fat distribution was not affected by inclusion level of Ca-PFA at a level of 15%. In conclusion, the inclusion of Ca-PFA in the diet until 15% decreased feedconsumption and produced similar growth performance, however it increased unsaturated fatty acid,omega-3 fatty acids and decreased body fat of broiler.

Abstract

The experiment was carried out to investigate the effect of turmeric extract on blood parameters,feed efficiency and abdominal fat content in broilers. A total of 100 mixed-sexes Lohman chicks wereused in the experiment set up with completely randomized design of 5 different doses of turmeric extractgiven orally start from day-15 to day-35. The chicks given no turmeric extract were used as a control(T0), whereas T1, T2, T3 and T4 were the chicks given turmeric extract of 200, 400, 600 and 800mg/kg-live BW, respectively. Hemoglobin values of broilers given turmeric extract 800 mg/kg-live BWwas significantly higher (p<0.05) at week-3 and week-4, but not at week-5, compared to broilers giventurmeric extract with lower doses or control group. Turmeric extract did not affect significantly (p>0.05)the concentration of erythrocytes, the levels of hematocrit as well as FCR and abdominal fat content ofbroiler. Turmeric extract seemed to be able to improve the digestion and metabolism (of fat) resulted inenhanced production of hemoglobin in broilers. The hypolipidemic effect of turmeric that could hamperits potential to promote the growth of broilers per se might explain why turmeric could not improve thefeed efficiency of broiler.

Abstract

The aim of study was to evaluate the effect of dietary vitamin E supplementation in Kedu andCemani hens reraed in situ and given farmer-formulated diet on egg performances. A total of 120 femaleand 24 male birds were equally divided into two groups of Kedu and Cemani, with average body weightof 1890+216.79 and 1830+396.23 g, respectively. Basal ration was based on the diet formulated by thefarmer (R1) consisting of corn (30%), rice bran (50%), protein concentrate (15%), and premix (5%).Dietary treatments evaluated were R1 (without additional vitamin E), and the other three were theinclusion of DL α-tocopheryl acetate into the R1 diet up to 2 (R2), 4 (R3) and 6 IU (R4). The experimentwas arranged in a Randomized Block Design with 4 treatments, and 2 different groups of hen (Kedu andCemani) were assigned as block. Parameters observed were feed consumption, hen day production, feedconversion ratio, egg quality, fertility, and hatchability. The result showed that vitamin Esupplementation did not affect whatever parameters, except egg fertility. Egg hatchability between Keduand Cemani hens was significantly different (p<0.05). Trend comparison test indicated significantlylinear (p<0.05) for fertility and hatchability. In conclusion, vitamin E supplementation up to 6 IUincreased linearly egg fertility and hatchability of about 5-8%, and egg hatchability of Kedu hens washigher (11%) than that of Cemani.

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.

Abstract

The aim of this study was to find out the influence of vitamin-mineral supplementation ondigestibility and rumen fermentation in Bali cattle. The randomized block design with 4 treatments and 4replications were used in the research. In this study was used 16 Bali cattle with body weight around295.31+23.07 kg. Rations used in the treatments were Treatment A (control): rice straw ad libitum pluscommercial feed; Treatment B: Treatment A ration plus 0.2% vitamin-mineral in commercial feed;Treatment C: Treatment A ration plus 0.3% vitamin-mineral in commercial feed, and Treatment D:Treatment A ration plus 0.4% vitamin-mineral in commercial feed. Parameters measured were nutrientdigestibility, rumen metabolites and urinary allantoin. The results showed that supplementation ofvitamin-mineral at 0.2 - 0.4% in commercial feed did not increase the digestibility of dry matter, organicmatter, crude protein and crude fiber, except for dry matter and organic matter digestibilities at 0.2%supplementation (p<0.05). However, the vitamin-mineral supplementation increased concentrations ofpartial VFA and ammonia as well as for methane gas production, except for VFA and ammonia at 0.4%level. Vitamin-mineral supplementation at 0.2-0.4% level did not affected pH value of rumen fluid andurinary allantoin.

Abstract

Twelve growing female goats (Anglo-Nubian) were assigned to a multiple latin square designexperiment to evaluate the effectiveness of additions of nitrogen (N) supplements to a high isocaloricenergy ration on N utilization. In this experiment, microbial synthesis and N balance were assessed. Thedaily rations were either unsupplemented barley meal (BM), or BM supplemented with one of threenitrogen sources. All rations were isocaloric (3.0 Mcal ME/kg DM) and the N supplements weresoybean meal (BSBM), cottonseed meal (BCSM) or urea (BU) to provide 2.9% N in the concentratecomponent. The unsupplemented BM contained 1.7% N. The addition of N supplements to the rationenhanced N utilization in dairy goats. The organic matter (OM) intake, N intake, N balance, andmicrobial N synthesis for BM, BSBM, BCSM and BU were 660.5 g, 721.9 g, 728.1g and 703.5 g; 13.5g, 21.5 g, 20.9 g and 20.7 g; 2.7 g; 7.1 g, 5.4 g, and 5.7 g; and 14.1 g 19.1 g, 19.1 g, and 20.0 g,respectively. It can be concluded that when sufficient dietary energy was available for ruminal microbialactivities, the source of N did not affect N balance, and microbial N synthesis.
