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 diversity of leptin genes in cattle has an impact to the physiological function of the leptin hormone as anti-obesity. This study was aimed to determine polymorphisms of the Leptin gene based on Single Nucleotide Polymorphism on exon 3rd and their effect to body weight, of Padjadjaran sheep. DNA samples were obtained from the blood of 26 Padjadjaran rams 1 years. Data of leptin gene diversity were analyzed from the results of PCR product sequencing by Sanger Methode of 696 bp leptin exon 3. Point mutations (SNPs) on nucleotide sequence were analyzed using Bioedit and MEGA 7 Program. Growth parameters which were measured i.e. monthly body weight gain until one year of age. The association of leptin gene polymorphism with body weight was find out by unpaired T test. The results showed there were SNPs in Leptin gene in exon 3 of Padjadjaran sheep, namely g.170 G> A and g. 332.A> G. Both of these mutations are non-synonymous mutations because there were altered amino acids from Arginine to Glutamine. Genotyping was done based on the two mutations above and got two alleles G and A, each of which has an allele frequency of 0.75 and 0.25, with the frequency of each genotype, AG and GG was 0.5. There was not association between SNPs on leptin gene with body weight from birth to 12 months of age.

Abstract

The objectives of this study were evaluate the dietary turmeric powder and swangi fish meal onsize of muscle fiber diameter and fat tissue score of major pectorales and semimembranosus of quailmeat. Research was conducted based on 2x3 of factorial completely randomized design, in which thefirst factor was 2 types of diet, i.e. RA : standard diet; RB : 85% standard diet + 15% swangi fish meal,and the second factor was 3 levels of period time of turmeric powder addition, i.e. P0 : without turmericpowder; P1 : turmeric powder 54 mg/quail/day was given since quail age 210 days old; P2 : turmericpowder 54 mg/quail/day was given since quail age 14 days old. Difference of means between treatmentgroups were analyzed by Duncan’s Multiple Range Test in 95% significance level. The results showedthat combined treatment of tumeric powder with RA (P0 : 2.33 μm; P1 : 3.06 μm; P2 : 2.98 μm) and RB(P0 : 2.22 μm; P1 : 3.12 μm; P2 : 2.92 μm) increased (P<0.05) muscle fiber diameter on majorpectorales significantly. Muscle fiber diameter on semimembranosus were increased (P<0.05) bycombined treatment of tumeric powder with RA (P0 : 2.83 μm; P1 : 3.50 μm; P2 : 3.24 μm) and RB (P0= 2.85 μm; P1 = 3.28 μm; P2 = 3.33 μm). In conclusion, combined treatment of RA (standard diet) andRB (diet with Swangi fish meal) increased (P<0.05) the size of muscle fiber diameter in majorpectorales and semimembranosus.

Abstract

The objective of this study was to evaluate the survival of L. plantarumU40 quantified with real-time PCR during in vitro rumen fermentation. The experiment was arranged in a randomized block design with 3 treatments and 4 replications. Treatments were control, rumen fermentation inoculated with L. plantarumU40and L. plantarumU40 + glucose solution. Population of L. plantarum U40 was higher at inoculation treatment. After 8 hours incubation, glucose addition tended to decrease L. plantarum U40 population. Control treatment showed lowest population of L. plantarum U40 along in vitro fermentation compared with other treatment. Inoculation of L. plantarumU40 significantly (p<0.05) increased population of LAB until 12 hours incubation compared with control. Control treatment had highest pH at all incubation time. Glucose addition significantly (P<0.05) decreased final rumen pH (24 hours) (6.30), compared with control treatment (6.85). Inoculation of L. plantarum U40 with glucose addition significantly (P<0.05)increased propionic acid, decreased acetic acid and A/P ratio compared with other treatments. Lactobacillus plantarum U40 without glucose addition did not affect propionic acid production significantly. As conclusion, Lactobacillus plantarum U40 can survive in rumen fluid and changes rumen fermentation when glucose is added as carbon source.

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

An experiment was conducted to observe the effect of different diets containing different level ofnon-starch polysaccharides (NSP) on performance and cannibalism of laying hens. Six diets (wheatbased,rice hull-based, plant protein-based, millrun-based, MOS, and bentonite) were used and wererandomly given to 6 groups of ISA Brown hens, with 18 replicates per group and 5 birds per replicatefor 8 weeks. The results showed that diets did not have a significant effect (P>0.05) on cannibalismmortality, but numerically the rice hull diet gave the lowest effect, the millrun gave the intermediateeffect, whereas the plant protein diet gave the largest negative effect. Diet significantly affected feedintake (P<0.01), egg production (P<0.01), feed to egg ratio (P<0.01) and egg weight (P<0.05). Birds onmillrun diet had the lowest intake, but the feed to egg ratio was superior and egg production was thehighest compared to those fed other diets. In contrast, the feed to egg ratio in rice hull diet was inferior,and egg weight was also lighter than those fed other diets. In conclusion, fibre sources have beenverified as contributing factors involved in the outbreak of cannibalism in laying hens. Diets containinghigh insoluble NSP had a potential to decrease the mortality due to cannibalism.

Abstract

This study aimed to evaluate the administration of Lactobacillus plantarum AKK-30 and Saccharomyces cerevisiae B-18 as probiotics in reducing cholesterol of blood, egg, and meat and also the production performance of laying quail (Coturnix coturnix Japonica). A number of 600 birds of the twenty one-day-old quails were distributed in a completely randomized design with 5 treatments and 6 replications (initial BW= 101.35 ± 1.64 g). Treatments were as follows: A = negative control (basal diet without probiotic), B = 1% of L. plantarum AKK-30 (107 cfu/g), C = 1% of S. cerevisiae B-18 (106 cfu/g), D = 1% of a probiotic consortium, E = positive control (commercial probiotic). Parameters observed were blood biochemistry profiles, product quality, and production performance. The results revealed that administration of 1% S. cerevisiae (C) resulted the lowest cholesterol in blood (101.75 mg/dL) and egg (9.44 mg/g) and while administration of 1% L. plantarum(B) increased meat protein and decreased fat content (P<0.05). Level of blood triglycerides, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were not different among treatments. Probiotic treatments did not affect the growth performance, quail day production (QDP), feed conversion ratio (FCR) and egg uniformity. However, probiotic increased diameter of egg yolk (P<0.05). It was concluded that administration of single probiotic L. plantarum AKK-30 or S. cerevisiae B-18 improves the quality of laying quail products.
