Abstract

Penelitian dilakukan untuk mengetahui degradabilitas nutrien bahan kering, bahan organik dan neutral detergent fibre pada bagasse amofer dan bagasse tanpa amofer pada domba secara in sacco. Materi penelitian adalah dua ekor domba jantan berfistula, ransum standar, bagasse amofer dan bagasse tanpa amofer. Degradabilitas dilakukan menggunakan metode in sacco. Sampel dimasukan dalam kain nilon kemudian diinkubasikan pada 7 titik waktu (0, 3, 6, 12, 24, 48 dan 72 jam). Parameter yang diteliti adalah degradasi bahan kering (BK), bahan organik (BO) dan neutral detergent fibre (NDF) dihitung dengan persamaan eksponensial, P = a + b (1?exp-ct). Uji t dilakukan untuk mengetahui ada tidaknya perbedaan diantara kedua perlakuan bagasse. Hasil penelitan menunjukan bahwa perlakuan bagasse amofer berpengaruh nyata (P<0,05) lebih tinggi dibanding bagasse tanpa amofer terhadap degradasi BK, BO, dan NDF. Simpulan penelitian yaitu pengolahan bagasse amoniasi dan fermentasi mampu meningkatkan degradabilitas nutrien bahan kering, bahan organik dan neutral detergent fibre.

Abstract

The objective of this research was to study the effects of synchronization of carbohydrate and protein supply in sugarcane bagasse based ration on the body composition of sheep. The studywasconsistedoftwo steps of experiment. The first step of experiment used two rumen cannulated adult rams to create formulation of three diets with different synchronization index, namely 0.37; 0.50 and 0.63 respectively. The experimental diets were designed to be iso-energy, iso-nitrogenous and iso-neutral detergent fibre (iso-NDF). The second step of experiment was to determine the body composition of sheep fed the experimental diets, which were created in the first experiment. The body composition of fifteen rams were determined on week 0; 4; and 8 of experimental period, these were accomplished using the technique of urea dilution. The alteration of synchronization index did not affect on feed intake, ratio of ruminal acetate to propionate and serum glucose concentration, but dry matter (DM) digestibility was affected (P<0.05) by the treatment of synchronization index in the diet. The alteration of synchronization index in the diet did not affect on the percentage of body protein, fat and water significantly, though body weight of sheep gained slightly during the experimental period.

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.

Abstract

The experimental research was conducted to clarify the effect of synchronization of ruminal carbohydrate and protein releases from sugarcane bagasse based diet (SBBD) on microbial protein synthesis in sheep. The first experiment was the formulation of three SBBD with similar nutrient content but differed in synchronization indexes (namely 0.36; 0.50 and 0.63). The in sacco nutrient degradability coefficient was used to calculate the synchronization index of each feedstuff. The second experiment was determination of post feeding ruminal pH, ruminal concentrations of total volatile fatty acids (TVFA) and ammonia nitrogen (NH3-N), and blood urea nitrogen (BUN) level in sheep fed on experimental SBBD. The third experiment was determination of feed digestibility and estimation of microbial nitrogen synthesis (MNP) on the basis of excreted urinary allantoin. The alteration of dietary synchronization index did not change nutrient intake, but the digestibilities of DM, OM and CP were increased (P<0.05). The post feeding ruminal pH was decreased (P<0.05) but concentrations of post feeding ruminal TVFA and NH3-N, and level of BUN were increased (P<0.05) by the treatment of dietary synchronization index. The treatment of dietary synchronization index improved MNP (P<0.05), although dietary synchronization index at 0.63 lowered the MNP (P<0.05).

Abstract

The study was aimed to predict body composition of local goats fed bagasse based total mixedration (TMR). Fifteen male local goats (18 months old with average body weight of 18 kg ) were used inthis study. Goats were divided randomly into 3 groups, and were fed TMR’s those contained 15, 25, and35% of sugarcane bagasse, respectively. All experimental diets were designed to be isoenergy andisoprotein. After 12 weeks of adaptation to experimental diets and environment, each group wassubjected to feed digestibility trial, body composition, and experiment of feeding effect on serumglucose. The data were analyzed using one way analyses of variance. The results showed that the bodycomposition and serum glucose concentration were not significantly different (P>0.05) amongtreatments. The bagasse portion in the TMR upto 25% lowered daily feed consumption and body weightgain (P<0.05). It was concluded that the use of sugarcane bagasse up to 35% in the TMR did not affectbody composition of goats.

Abstract

This study was conducted to evaluate diets containing durian (Durio zibethinus Murr) seed meal (DSM) on the performance, nutrient retention and egg qualities of commercial layers. A total of 120 fifty two -week-old laying hens were distributed according to a completely randomized design in four treatments and five replications with six birds each. The treatments consisted of different levels of durian seed meals (control, 3% DSM, 6% DSM, and 9% DSM). Feeding diets containing durian seed meal had no significant effect (p > 0.05) on the feed consumption of laying hens at 58 wk of age. Inclusion of up to 6% DSM in formulated layer diets did not reduce egg production and nutrient digestibility, but reduced egg weight. No differences (p>0.05) were observed in egg calcium content, egg calcium mass, and yolk color score fed diets containing DSM. This study suggests that DSM could be incorporated up to 6% in laying hen diets without adverse effect on production performance, nutrient retention and egg qualities.

Abstract

Fifteen Jawarandu male goats were used to study the effect of different portion of sugarcanebagasse in diets on some parameters of protein metabolism. Goats had average of body weight of 18 kgand aged at 18 months. Animals were housed in metabolic cages and were alloted to a completelyrandomized design receiving three experimental diets with sugarcane bagasse portions of 15, 25, and35% (dry matter basis), respectively. After eight weeks of adjustment period to experimental diets andenvironment, each group of treatment was subjected to ten days of digestion trial, and followed bycollection of rumen liquid samples. Parameters observed were feed digestibility, nitrogen retention,ruminal feed fermentation, and excretion of urinary allantoin to estimate microbial protein synthesis.Data were tested using one way analysis of variance, and followed by Duncan’s mulitiple range test. Drymatter and protein intakes lowered (P<0.05) as the increasing of sugarcane bagasse in diets. Proteindigestibility and retention were unaffected by the treatment of bagasse portion. The dietary treatment didnot change ruminal ammonia, total VFA, acetate, propionate, and butyrate concentrations. Microbialnitrogen synthesis and efficiency of microbial nitrogen synthesis were unaffected by the dietarytreatment.

Abstract

Two adult male sheeps fitted with rumen cannula were used in two experiments to study the effects of synchronization of carbohydrate and nitrogen supply in sugarcane bagasse based total mixed ration (TMR) on in situ nutrient degradation. The first experiment was aimed to create three TMR with different synchronization index. Ingredient feedstuffs of TMR were evaluated for its in situ organic matter (OM) and nitrogen (N) degradation kinetics. On the basis of the OM and N degradation kinetics of feedstuffs, three sugarcane bagasse based TMR were formulated with synchronization indexes of 0.37; 0.50; and 0.63; respectively. The TMR had similar levels of crude protein (CP), total digestible nutrients, and neutral detergent fiber (NDF). In the second experiment, the three TMR with different synchronization index were evaluated for in situ degradability characteristics of OM, CP, NDF, and sulfur. The in situ degradation of OM in TMR were decreased (P<0.05) with the increasing of synchronization index. The higher synchronization index in TMR increased (P<0.05) CP degradation of CP. The NDF degradation decreased slightly by the alteration of synchronization index in TMR. The higher synchronization index in TMR reduced (P<0.05) in situ sulfur degradation, and this may not support to effects of synchronization of carbohydrate and nitrogen supply.
