Abstract

The objective of the research was to examine unfermented solid cassava-waste (USCW) andfermented solid cassava-waste (FSCW) as the substitution of corn in broiler ration. Two hundred and tenbirds of one-week-male broiler chicken were divided into seven kinds of one-way treatment ofcompletely randomized design. Five replications were used for each treatment; there were six chickensin each replication. The substitution levels of corn in broiler ration by USCW and FSCW were 0%(control), 10, 20, and 30%. The result showed that corn substitution up to 20% using USCW and FSCWdid not affect the digestibility of feed (DF), digestibility of soluble protein (DSP) and crude protein(DCP), and digestibility of starch (DS). Substitution up to 30% using FSCW did not affect the DSP andDCP. However, substitution of USCW at the same level decreased DSP, DCP, DF, and DS. Cornsubstitution up to 20% using USCW and FSCW did not affect the feed intake (FI), body weight gain(BWG) and feed conversion ratio (FCR). Substitution up to 30% using FSCW did not affect the BWGand FCR. However, substitution of USCW at the same level decreased BWG and increased FCR. FSCWcan be used as a substitute for the corn up to 30% without affecting the performance and the values ofthe nutrient digestibility, meanwhile USCW is only able to substitute corn up to 20%.

Abstract

The present study was conducted to evaluate the effect of Sauropus androgynus (katuk) leavesextract (SAE) and lemuru fish oil (LO) on fat deposition and fatty acid composition of meat in broilerchickens. One hundred and fifty six broiler chickens were distributed to 13 treatment groups with 3cages in each treatment group as replicate. Completely randomized design was used in this study. Thethirteen groups were subsequent of broiler chickens that were fed diet containing commercial feedsupplement as a control (P1), 10 g/kg SAE and 1% LO (P2); 10 g/kg SAE and 1% LO plus 60 mgvitamin E (P3), 10 g/kg SAE and 2% LO (P4), 10 g/kg SAE and 2% LO plus 60 mg vitamin E (P5), 10g/kg SAE and 3% LO (P6), 10 g/kg SAE and 3% LO plus 60 mg vitamin E (P7), 18 g/kg SAE and 1%LO (P8), 18 g/kg SAE and 1% LO plus 60 mg vitamin E (P9), 18 g/kg SAE and 2% LO (P10), were18 g/kg SAE and 2% LO plus 60 mg vitamin E (P11), 18 g/kg SAE and 3% LO (P12), and 18 g/kg SAEand 3% LO plus 60 mg vitamin E (P13). The data were analyzed by analysis of variance and if it weresignificant, it were then determined by Duncan's Multiple Range test. The present results showed thatsupplementation of SAE and LO significantly affected (P<0.05) fat deposition in abdomen and leg, butit had no effect on neck fat deposition and Fatty Liver Score. Supplementation of SAE and LO hadsignificantly reduced (P<0.05) cholesterol content and thiobarbituric acid (TBA) in leg meat, but itsignificantly increased (P<0.05) vitamin A and vitamin E and it had no effect on fat in leg meat.Supplementation of SAE and LO proved to change fatty acid composition in leg meat. The treatmenthighly significant increased ecosapentaenoic acid (EPA) and docosahexaenoic acid DHA (P<0.01),arachidonic acid and stearic acid (P<0.05), but it significantly reduced linolenic acid (P<0.05). Inconclusion, the supplementation of SAE and LO reduced fat deposition in abdomen and leg, the contentof cholesterol in meat, and it enriched EPA and DHA of meat.

Abstract

Forty laying hens Hysex Brown consisting of 2 age groups (27 and 77 weeks of age) were used inthe study to elucidate the hypocholesterolemic effect of garlic powder on egg production, serum and eggcholesterol. They were caged individually and fed diet containing 0 (control), 1, 2, and 4% oven driedgarlic powder for 4 periods of 4 weeks. The old hens consumed more food compared to those of theyoung one, while water consumption was in the reverse condition. The egg production indicated by theyoung hens fed dietary 1 and 2% garlic powder was significantly higher than those fed control diet.However, the old hens produced heavier eggs than those of the young hens, particularly when 1% garlicpowder was supplemented. There was a closed relationship between serum and egg cholesterol, whichreduced gradually with longer time the hens fed dietary garlic. The results clearly demonstrated that thelaying hens fed dietary garlic powder up to 4% produced egg containing lower cholesterol (-34%)compared to those fed control diet; The hypocholesterolemic effect of garlic powder is apparently higherin the old hen compared to that in the young hen.

Abstract

A study was conducted to collect information on Bali bulls carcass traits estimation as one of theselection criteria using ultrasound. Ultrasonic estimation of carcass traits such as M. longissimusthoracis area (MLTA), Subcutaneous Fat Thickness (SFT), Inter Muscular Fat Thickness (IMFT), RibThickness (RT) and Beef Marbling Score (BMS) were obtained from 92 head of bulls at Barru districtand 74 head of bulls at Bone district, South Sulawesi, Indonesia. The carcass traits estimation werescanned between the 6th - 7th ribs using ultrasound. The ultrasound is made of Fujihira Super-Eye FHK,Co. Meat. Ltd. with B-Mode and electronic linear probe, which used frequency of 2 MHz. The carcasstraits estimation photos were printed by video-copy machine (Aloka Co. Ltd., SSZ-300S). The dataobtained were analyzed using basic statistic and was discussed descriptively. The averages of all carcasstraits estimation of the Bali bull at Bone district at 12, 18 and 24 months of ages were higher than thoseat Barru district. The MLTA estimation of Bali bulls at Bone and Barru districts were 18.0 cm2, 24.3cm2, 23.8 cm2 Vs 16.6 cm2, 18.5 cm2, 23.3 cm2, respectively; the BMS estimated were 0.14, 0.24 and0.20 Vs 0.00, 0.15 and 0.17, respectively; the SFT estimation were 0.26 mm, 0.33 mm, 0.34 mm Vs0.28 mm, 0.26 mm, 0.34 mm, respectively; the IMFT estimation were 1.13 mm, 1.24 mm, 1.31 mm Vs0.97 mm, 1.06 mm, 1.14 mm, respectively; the RT estimation were 2.04 mm, 2.52 mm, 2.72 mm Vs1.19 mm, 2.12 mm, 2.30 mm, respectively. The growth of MLTA, SFT, IMFT, RT and BMS of thebulls of Bali cattle at the 12, 18 and 24 months of age were not reaching the optimally performances,yet. Therefore the selection process of the bulls of Bali cattle to be candidate of sire based on theestimation of carcass traits should be done after since 4 years of age.

Abstract

The research aimed to identify carcass characteristic that can be used for estimating composition ofbeef carcass. It was used 165 Brahman crossbred cattle in this research. Carcass characteristics wereweight of a half cold carcass (WC) ranged from 96 to 151 kg, loin eye area (LEA) ranged from 22.09 to304.8 mm2, 12th rib fat thickness (FT12) ranged from 0.80 to 2.90 mm, meat ranged from 53.55 to 90.10kg and carcass fat ranged from 5.54 to 39.72 kg. Result showed that a half weight cold carcass as asingle indicator major may be used to predict meat weight and carcass fat with regression linearequation: Meat (kg) = 10.64 + 0.49 WC (R2=0.728 and SE=3.58), and Fat (kg) = -21.70 + 0.36 WC**(R2=0.582 and SE=3.65). Multiple regression to predict meat weight based on fat percentage of kidney,pelvic and heart (KPH) was Meat (kg) = 7.99 + 0.58 WC** - 4.41 KPH** (R2=0.751 and SE=3.43).

Abstract

Post-mortem spermatozoa recovery is an important technique for obtaining germplasm reservesfrom genetically valuable animals or endangered species. The purpose of this study was to studywhether ram spermatozoa within epididymides stored at 4º C for 24 and 48 h remain their motility andviability. The characteristic of ram epididymal spermatozoa after freezing and thawing was alsoobserved. Six pairs of ram testes with attached epididymides were used in this study. The motility ofcontrol spermatozoa was well maintained throughout the dilution procedure (83.3±1.1, 80±1.3, and80±1.3% for collection, Niwa and Sasaki freezing -1 extender (NSF-1 and NSF-2 groups respectively);but declined (P<0.05) after freezing and thawing (38.3±3.1%). Motile and viable spermatozoa could berecovered from epididymides up to 48 h of storage, although their quality declined significantly(P<0.05) as post-mortem storage time increased (motility: 83±1.2, 67±3.0, and 46±5.1; viability:84.2±2.4, 73±2.8, and 66.6±2.6 % for control, 24 h and 48 h group respectively). These data indicatethat ram epididymides could be stored at 4º C for 48 h when epididymal spermatozoa cannot beimmmediately collected and cryopreserved. These storage conditions might be possible to use forepididymal sperm recovery in wild ruminants.

Abstract

This research was aimed to examine the effect of undegraded protein supplementation on nutrientsintake, production and milk composition in dairy cows. The purpose of this research was to provideinformation on the undegraded protein supplementation to increase milk production and composition indairy cows. The research was conducted for 3 months in Boyolali-Central Java. The study used 20lactation cows (<3 months of lactation), aged 3 to 3.5 years with body weight from 350 to 400 kg. Thecows were then randomly divided into 2 groups of ten based on their body weight, milk production,lactation period and age. The first group (control) and the second group (treated), both were fed dietbased on NRC (1987). The second group was added undegraded protein (UDP) of 30 g/l milk that mixedby concentrate. The observed variables were dry matter intake (DM), organic matter (OM), crudeprotein (CP), neutral detergent fiber (NDF), milk production and milk composition including fat, proteinand solid non fat (SNF). Data obtained were examined by t-test.The results showed that intake of DM, OM, and the NDF of treated and control groups were notdifferent (9.57; 8.49; 4.98 vs 9.44; 8.38; 5.40 kg/cow/d, respectively); however, protein intake of treatedgroup was higher (P<0.01) than that of the control group (1097 vs. 1210g/cow/d). Milk production ofcows receiving UDP supplementation tended to be higher than that in the control group (+ 1:45kg/cow/d). Although they tended to be lower in fat (4.13 vs. 3.88%), protein (2.45 vs. 2.27%) and SNF(7.26 vs. 6.94%), but protein and fat production were higher for cows receiving UDP supplementation(366 each; 214 vs. 330; 196g/cow/d). It can be concluded that UDP supplementation increased milk, fatproduction and milk protein but it tended to reduce the level of fat, protein and SNF milk.

Abstract

s to assess different CPAs on stallion semen cryopreservation. Skim milk (SM) and Dimitropoulos(DV) were the extenders used in this study; each was added by glycerol (Gly), combination of ethyleneglycol-glycerol (EG+Gly) or dimethilformamide (DMF). Each semen sample was evaluated and dividedequally into six tubes; semen in the three tubes was diluted 1:1 with (SM), while in the remaining tubesthe semen was diluted 1:1 by DV. After being diluted, all tubes were centrifuged at 1006xg for 10minutes. The supernatan discarded, the pellet was rediluted by SM trehalosa or DV trehalose, and addedby G, EG+Gly, or DMF to reach the final sperm concentration of 200x106/ml. The extended semen wasindividually packed in 0.3 ml minitube, equilibrated at 4oC for 2 hours, frozen in liquid nitrogen vaporfor 10 minutes, and then was stored in liquid nitrogen container at -196 oC. After 24 hours, the semenwas thawed at 37 oC for 30 second. There were no significantly different (p>0.05) on the percentages ofmotile and viable sperm in SMT (21.7% and 43.4%, respectively) compared with those extended withDV T extender (26.9% and 50.8%, respectively). DMF demonstrated better results as CPA compared tothe others; and DVTDMF combination had the best protection during cryopreservation in this study.

Abstract

Lignin is limiting factor for cellulose and hemicellulose degradation in rumen. Isolation andselection bacteria from buffalo and horse gastrointestinal tract and elephant dung could be foundbacteria that have superiority to degrade lignin, xylan, and cellulose. Those animals were chosenbecause they were herbivores that consume low quality crude fiber as their main energy sources.Lignocellulose degrading bacteria were isolated by Hungate selective media, by using lignin (tannicacid), xylan, and cellulose as selective substrates. The morphological identification used an enrichmentmedia by measuring color, colony size, diffusion zone, clear zone, and biochemical identification usingproduction of ligninase, xylanase, and cellulase enzymes. The best lignocellulose degrading bacteriathen was determined by the morphological and biochemical character. This study showed thatlignocellulose degrading bacteria could be found in gastrointestinal tract of buffalo and horse, andelephant dung. Highest number colony was found in samples from buffalo's colon (376), followed byhorse's cecum (203), elephant’s dung (46), buffalo’s cecum (23), buffalo's rumen (9) and horse’s colon(7). The highest isolates activity of lignolytic, xylanolytic, and cellulolytic were reached by buffalo’scecum (7.64), horse's cecum (6.27), and buffalo’s colon (2.48). Meanwhile the highest enzymesproductivities were: buffalo’s cecum (0.0400 µmol), horse’s cecum (1.3912 µmol) and buffalo’s colon(0.1971 µmol). Based on morphologycal character and biochemical test, it could be concluded thatlignolytic from buffalo’s cecum, xylanolytic from horse’s cecum, and cellulolytic from buffalo’s colonwere the superior isolates and they were 99% analyzed as Enterococcus casseliflavus/gallinarumspecies.

Abstract

An experiment imposing the multi continuous phase feeding was carried out to evaluate the EFG(Emman, Fisher and Gous) Growth Model in its capacity to predict amino acid requirements in broilers.Birds were fed using blended summit (247.91g/kg CP, 3200 kcal of ME /kg) and dilution (166.26 g/kgCP, 3200 kcal of ME g/kg ) diets and offered to 2-4 or 8 phases. Two hundred male day-old broilerchicks of two commercial strains (A=Ingham and B = Steggles) were used. The predicted responseswere greater than the observed both gain (g/d) and feed intake (g/d). The discrepancy between theobserved and predicted gain in the strain A and B birds, showed a different pattern, with a markeddifference during the early growing period, with a degree of convergence in the late growing period forthe strain A but the reverse picture for the strain B. This shows that strain characterization is notaccurate due to an inadequate definition of the genotypes by the model. Non agreement betweenpredicted and determined gain and feed intakes provided little benefit in moving towards a morefrequent change in diet to accommodate predicted growth-related changes in amino acid requirements.
