Abstract

The present study was designed to evaluate the effectiveness of Sauropus androgynus leavesextract (SALE) plus turmeric powder (TP) on carcass quality and blood profile in broilers fed lowprotein diets. Sixty broilers aged 14 days were divided to 5 treatment groups as follows: 1) Broilers fed19% protein diet without SALE plus TP as control (P0); 2) Broilers fed 17% protein diet supplementedto 4.5 g SALE/kg diet plus 0.5% TP (P1); 3) Broilers fed 17% protein diet supplemented to 4.5 gSALE/kg diet plus 1% TP (P2); 4) Broilers fed 15% protein diet supplemented to 4.5 g SALE/kg dietplus 0.5% TP (P3) and; 5) Broilers fed 15% protein diet supplemented to 4.5 g SALE/kg diet plus 1%TP (P4). Supplementation of SALE plus TP significantly affected body weight gain, feed intake, proteinintake, thigh meat haemorrhage and fat deposition (P<0.05). No significantly different was observed oncarcass odor, shank color, breast meat haemorrhage, leg and breast weight, meat cholesterol, fatty liverscore and tocixity (P>0.05). In conclusion suplementation of SALE plus TP had no beneficial effect onreducing fat deposition in broilers fed low protein diets, but it reduced blood uric acid but increasedblood glucose concentration.

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

The mechanism of the hypothalamus, pituitary, and ovaria is important in the early postpartum luteal activity. This study aims to measure levels of the leptin hormone, Luteinizing Hormone (LH) during the first-time postpartum estrus appears and to observe the signs of estrus. The study uses a prospective observational method. The samples were Bali cattle on peripartum conditionwhile postpartum estrus appeared from several sistem pertanian terintegrasi (Simantri) in Mengwi District, Badung Regency, Bali, Indonesia. The measured parameters were leptin levels, LH, and the onset of postpartum estrus. The technique of measuring hormone levels with the Direct Elisa method and Double Antibody Sandwich. The results showed there were a positive correlation (r=0.773) between leptin levels at peripartum and the onset of postpartum estrus.The higher level of leptin, the faster of postpartum estrus appears. However, a minimum leptin value is needed to increase the LH level so that expression of estrus appearance is clearly.

Abstract

The objectives of this study were to determine socio-economic factors that influence milkconsumption and propensity to routine milk consuming in a household that have children in growing agein both urban and rural area of Yogyakarta Special Province. Numbers of respondent were 122households in urban area and 102 in rural area. Survey method was used to collect data usingquestionnaires presented to respondents. The data were analyzed quantitatively using a log linearmultiple regression and binomial logistic regression models. Results of the research showed that milkprice and mother’s education background were highly significant factors in determining the milkconsumption expenditure. Individually, the income was not significant factor. Furthermore, urbanhousehold group with higher mother’s education and household income were different significantly withthe rural one. A number of children who were less than 12 years old had significantly greater propensityto consume milk routinely. The program to increase milk consumption for children in growing ageshould be focused on improving the knowledge of mothers in low income communities especially inrural areas accompanied with required skills to get employment opportunities and extra cash income.

Abstract

Ettawa Grade (PE) are potentially developed goats to produce milk and meat. Milk is food of animal that is rich in nutrients, but it is a perishable food easily contaminated by microorganisms. Contaminated pathogenic bacteria in milk can decrease the quality and has an organoleptic effect on milk, as well as endangers human health. Milk contaminated with bacteria antimicrobial resistance (AMR) in which is resistant to antibiotics, may adversely affect the response to treatment with antibiotics in humans when suffering from infectious diseases and using antibiotics in therapy. In this study Ettawa Grade's samples of fresh milk and other dairy products were taken from some of the goat farms in Yogyakarta Sleman district. The samples were tested for the presence of pathogenic bacteria and for its resistance to several kinds of antibiotics. In this study 35 Ettawa Grade's samples of fresh milk and other dairy products (fresh milk, milk powder, ice cream, and yoghurt) were taken from some of the goat farms in Sleman district-Yogyakarta. The samples were tested for the presence of pathogenic bacteria and for its resistance to several kinds of antibiotics. The result of the prevalence of pathogenic bacteria in goat fresh milk and other dairy products was 15% Escherichia coli and had multi resistance to multiple antibiotics, namely ampicillin, colistin sulphate, cefixime, kanamycin, oxytetracycline, tetracycline and sulfonamide.

Abstract

A 75 days feeding trial was completed to study the effect of inclusion of a combined probioticyeast+herbs in finishing diet on carcass characteristics of beef cattle. Thirty bull of Ongole crossbred,age 2.5-3 years old with average body weight (BW) of 320 kg were used in this experiment. They weredivided into 2 groups, each of 15 animals and were allotted to control and treatment. They wereslaughtered at around 450 kg BW. The treated animals were given a supplementation containingcombined yeast (Saccharomyces cerevisae and Candida utilis) and herbs. All animals were fed a diet ofammoniated rice straw and commercial concentrate with a ratio of 10: 90. Addition of combinedprobiotics + herbs in the diet increased percentage of carcass, dressing and meat, but there were noeffect on live weight gain (LWG), % bone, meat:bone ratio, % body fat, back fat thickness and eyemuscle area. There was a reduction in the percentage of offal due to a decrease in intestinal weight in thetreated animal.

Abstract

Ongole Grade cattle is one of local cattle in Indonesia.This study was aimed to analyze the effect of bull age and season on semen quality of Ongole Grade cattles macroscopically (sperm motility, and sperm concentration) and microscopically (semen ejaculate volume) to support the policy and management on improvement of semen production. Data were collected from 533 ejaculates of 10 bulls aged 3, 4, and 5 yr at Singosari National Artificial Insemination Center(SNAIC). The 4-year-old bulls hadhighestsperm motiliy and semen ejaculate volume. The lowest ejaculate volume was reported in Ongole Gradecattlesaged 3 yr. Sperm motility and concentrationweresignificantly higher (P<0.01) in wet season than dry season. In conclusion, the bull age and season should be considered by Singosari National Artificial Insemination Centerwhen collecting the semen, especially on bulls aged 3 yr old and in dry season.

Abstract

This experiment was aimed to study the degradation kinetics of limestone-urea mixtures in the goats rumen using the nylon bag technique. Samples of limestone were obtained from two limestone mountains, Pamotan Subdistrict of Central Java Province and Wonosari Subdistrict of Yogyakarta Province. The mixtures were created by combining urea at levels 25, 50, 75and 100%; respectively with two limestones on the basis of their Ca contents: L0U100, LP25U75, LP50U50; LP75U25, LW25U75; LW50U50; and LW75U25. The soluble fraction, potentially degradable fraction, the degradation rate of potentially degradable fraction, and effective degradation of respective dry matter (DM) and nitrogen (N) ruminal degradation kinetics were measured in each mixture. The mixture of LP75U25 had lowest effective and degradation rate of potentially degradable fraction (P<0.05) respectively for DM and N compared with those of other mixtures. In conclusion, the limestone-urea mixture of LP75U25 could be suggested as a dietary supplement of ruminal N slow release.
