Abstract

The aims of this study were to estimate the heritabilities, examine the effects of dairy femaleselection and calculate the genetic gains on milk yield and milk composition in Baturraden Dairy CattleBreeding and Forage Centre (Balai Besar Perbibitan Ternak Unggul dan Hijauan Pakan Ternak /BBPTU–HPT Baturraden), Indonesia. The first lactation records of 221 dairy cows from 2006 to 2014were used. Heritabilities were estimated by paternal half-sib correlation. Comparison of averageperformances between daughter population (Ā) and initial dam population before selection ( ) wereconducted by Z-test. Annual genetic gain was calculated as genetic gain per generation (the differencesbetween Ā dan ) divided by generation interval. Heritabilities for milk fat percentage (FP), milk fatyield (FY), milk protein percentage (PP) and milk protein yield (PY) were 0.46, 0.30, 0.28 and 0.17,respectively. A significant increase (P=0.025) in the total milk yield (TMY) from the first generation(G1) to the second generation (G2) resulted in a high significant decrease in the FP (P=0.004). Geneticgains of TMY, FP and PP were 9.76 kg, -0.04% and -0.01% per year, respectively. It is concluded thatselection for higher TMY only negatively affect FP and PP. Selection can be applied based on FY to avoid the decrease of FP. Negative effects of genetic-environmental interaction resulted in slowergenetic gain because the imported cows needed time to adapt to the local environment.

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 purpose of this research was to determine the reproductive quality of normal compared withabnormal postpartum estrus (PPE) of Jawa Randu Goats (n = 16 goats) on estrogen hormon level andestrus profile. Total samples were 16 Jawa Randu goats. The data were analyzed descriptively and nonparametric data were analyzed using Mann Whitney U-test of Statistical Package for the Social science(SPSS) 16. Descriptive statistics was used on estrogen hormone and resulting that normal postpartumestrus (PPE) Jawa Randu Goats had a better level (133.8; 141.5; 155.6; 162.25; 167.75 pg/mL)compared with abnormal postpartum estrus of Jawa Randu Goat (109.9; 111.35; 101.2; 132.2; 142.45pg/mL). Mann Whitney U-test used for the abundance of cervical mucus and ferning showed nonsignificantly different of postpartum estrus between both groups. Jawa Randu goats with normal PPEhad a higher estrogen level than abnormal PPE goats. However, for the abundance and ferning ofcervical mucus, between the two groups of goats was not different.

Abstract

The present study was conducted to investigate the effects of duration and temperature storageof sheep ovaries on nuclear maturation in vitro of oocytes obtained from stored ovaries. Ovaries werecollected from slaughterhouse and stored in physiological saline for 2-4 h, 5-7 h and 8-10 h at varioustemperatures (27-28°, 36-37° and 4°C). Cumulus oocyte complexes (COCs) were collected with slicingmethod from each group and matured in vitro for 26 h. There was no difference between the proportionsof oocytes maturation to metaphase II when collected from ovaries stored at 27-28°C and 36-37°C for 2-7 h of slaughter. However, the percentages of oocytes from ovaries stored at 4°C were significantlylower (P<0.05) than those stored at higher temperature (69.23%, 70.83% and 45.65%, for 27-28, 36-37and 4°C at 2-4 h, respectively; 59.61%, 64,58% and 36.36% for 27-28, 36-37 and 4°C at 5-7 h,respectively). The proportion of oocytes meiosis to metaphase II (MII) were significantly (P<0.05)decreased when the ovaries stored at 27-28 and 36-37°C for 8-10 h, but not in oocytes stored at 4°C(24.37%, 7.84% and 45.23%, respectively). The maturation rate of oocytes from ovary stored at 4°C washigher than those collected from ovaries stored at higher temperature (P<0.05). This finding indicated that the storage of ovaries at 4°C for 8-10 h is effective for maintaining the development competence ofsheep oocyte better than storage at higher temperature.

Abstract

Sixteen Ettawah cross bred goats were used to study the effect of waru leaf (Hibiscus tiliaceus)sapponin combined with soybean meal protein supplementation on some parameters of proteinmetabolism. Goats had body weight average of 16 kg and aged at 7 months. The experimental dietswere: T0 = total mixed ration (0.9% saponin of hibiscus leaf, 8% CP, 62% TDN), T1 = T0 + 3% soybeanmeal protein, T2 = T0 + 6% soybean meal protein, and T3 = T0 + 9% soybean meal protein. Thetreatments were allocated in a completely randomized design. The parameters observed in this studywere dry matter (DM) and crude protein (CP) intakes, DM and CP digestibilities, ruminal amonia andVFAs concentrations, blood urea level, nitrogen retention, digestible organic matter in rumen (DOMR),urinary allantoin, and estimated microbial nitrogen (N) synthesis. DM intake, DOMR, urinary allantoinand estimated microbial N synthesis were not affected significantly (P>0.05) by treatments. CP intake,DM and CP digestibilities, ruminal amonia and VFAs concentrations, blood urea level and nitrogenretention increased (P<0.05) with increasing levels of soybean meal protein. Balancing energy levelshould be considered for the dietary protein supplementation in Hibiscus tiliaceus leaf contained diet of goat.

Abstract

The study was aimed to improve the physical characteristics of culled duck meat using marinationin ginger extract and aging. The material used were Magelang culled ducks (2.5 years old). Gingerextract was derived from the rhizome of fresh ginger (Zingiber officinale Roscoe). The experimentalused was a factorial design (3x3), with two main factors, namely the concentration of ginger extract andaging time in completely randomized design. Level of ginger extract concentrations were 0, 5, 10% andlong times of aging were 24, 48, 72 hours as combination treatments, and replication for each treatmentwere 3 times. There was a significant interaction between the factors of aging time with ginger extractconcentration in influencing moisture, pH , hardness and the water holding capacity of culled Magelangduck meat. The best treatment to improve the physical characteristics of culled duck meat weremarination in 5% ginger extract and aging for 48 hours.

Abstract

A study was conducted to assess the genetic characterization of the Sumba Ongole (SO) cattlebased on DNA microsatellites and also to study the potency of SO cattle based on carcass productivity.Blood samples were collected from 28 individual cattle and 12 microsatellite primers as recommendedby FAO were used to identify the genetic characterization of the SO cattle population. Data of carcassproductivity were collected from 506 individual cattle that slaughtered in Karawaci abattoir, Banten,Indonesia. The heterozygosity values of microsatellite loci ranged from 0.143 to 1.000 (mean 0.536).The highest PIC values was 0.814 (locus TGLA122), while the lowest was 0.280 (locus BM1818).Cattle in range of 351-475 kg slaughter weight was most slaughtered in year 2013 and 2014 with carcasspercentage ranged from 52.89% to 53.43%. The highest carcass percentage (56.34%) was obtained fromcattle in range of 626-650 kg slaughter weight while the lowest (51.42%) was obtained from cattle inrange of 250-275 kg slaughter weight. The results of genetic characterization showed that allmicrosatellite locus were highly polymorphic and highly informative for detecting the level of geneticdiversity in the SO cattle population. The results of carcass productivity showed that the SO cattle hasexcellent potential as beef cattle compare with other local breeds cattle in Indonesia.

Abstract

This research was done to measure the added value of goat and sheep with cut and carry systemand influencing factors of goat/sheep productivity and to measure the added value of manure to palmproductivity. The research was done in Deli Serdang Regency by determining two districts as researcharea: Tanjung Morawa District and Bangun Purba District. Location was determined by purposivesampling technique based on population of small ruminants and area of oil palm plantation in bothdistricts. Sample consisted of 50 goat farmers and 50 sheep farmers. Results indicated that farmers have18 to 24 heads of goats or sheep. Performance of goat and sheep reproduction tended to similar togenereral performance. Amount of doe, feed from palm oil and intercropped plant, livestock type andlocation influence significantly at livestock productivity (P<0.01). Goat contributed manure 16.86% and11.26% of total palm trees in Tanjung Morawa and Bangun Purba, respectively, while sheep contributedmanure 21.49% and 22.56% of total palm trees, respectively. Therefore, it was necessary to increasepopulation of livestock, to increase technology and diversification of production. It may be done by establishing partnership with local government, animal of science office and private corporation .
