Abstract

The purpose of this research was to produce the enriched eggs, but low in cholesterol content. Forty eight layer chickens aged 72 weeks (strain Dekalb Warren) were distributed into six treatment groups. One group of laying hens was fed diets without Sauropus androgynusleaf extract (SALE) as the control, and another five groups were fed diet supplemented to 9 g SALE, 18 g SALE, 27 g SALE, 36 g SALE, and 45 g SALE/kg diet, respectively. Completely randomized design was used in the present study.The experimental results showed that SALE supplementation had no effect on egg production, feed intake, feed conversion ratio, egg weight, yolk weight, albumen weight, shell egg, egg index, eggshell thickness, and yolk index (P>0.05), but significantly affected Haugh Unit, albumen index, yolk color, egg odor, egg taste, and yolk color (P<0.05). The protein, fat, calsium, phosphor, kaliumand iron contents of eggs  did not change (P>0.05), but the cholesterol content of egg was significantly reduced (P<0.05). In conclusion, the supplementation of SALE did not enhance performance, but it improve egg quality and its chemical composition.

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

Calpain-1 gene (CAPN1) produces an calpain enzyme controlling structure of meat protein and tenderness. The aims of this study were to identify Single Nucleotide Polymorphism (SNP) in exon 5 and 6 of CAPN1 gene and its associate with carcass and meat characteristic traits in bali cattle. A total of 48 bali cattles from BPTU-HMT Bali Cattle, Bali Province were used in the research. SNP in exon 5 and 6 of CAPN1 gene were identify with direct sequencing using MEGA 5 program. Analysis of polymorphism was conducted by PopGen 1.32 software to identify frequencies of genotype, allele and Hardy-Weinberg equilibrium. The association of CAPN1 gene genotype with carcass and meat characteristic traits was analyzed using Generalized Linear Model (GLM) procedure of SAS. Sequencing analysis at exon 5-6 of CAPN1 gene in Bali cattle resulted in eight polymorphic SNPs. They are c.3669T>C, c.3854G>A, c.3881T>C, c.3899C>T, c.3908C>G, c.4002C>A, c.4021G>T and c.4037A>C. The SNPs c.3669T>C, c.3854G>A and c.3899C>T were significantly (P<0.05) associated with rump thickness (RT), rump fat thickness (RFT) and marbling score (MS), while SNP c.4037A>C was not significantly associated with carcass and meat characteristic traits. The SNPs were significantly associated with carcass and meat characteristic traits namely c.3669T>C, c.3854G>A and c.3899C>T. Those SNPs may be used as candidate marker for Marker Assisted Selection (MAS) in bali cattle.

Abstract

The purpose of the research was to assess the effect of α-tocopherol and ascobic acids on the performance and immunity blood profile of male native Muscovy duck. The materials used were 84 male Muscovy ducks at 9 weeks old. The research used completely randomized design with 7 treatments. The treatments were E0C0 : basal diet without α-tocopherol and ascobic acids, E400: basal diet+ α-tocopherol 400IU, E600: basal diet+α-tocopherol 600IU, C400: basal diet+ascorbic acid 400mg/kg, C600: basal diet+ascorbic acid 600mg/kg, E200C200: basal diet+α-tocopherol 200IU+ ascorbic acid 200mg/kg, and E300C300: basal diet+α-tocopherol 300IU+ ascorbic acid 300mg/kg. Each treatment was repeated 4 times and each replication consisted of 3 ducks. The observed variables were body weight, feed consumption, feed conversion ratio, packed cell volume (PCV), total of plasma protein (TPP), leucocyte count, basophil, heterophil, eosinophil, monocyte, lymphocytes count and heterophil/lymphocyte (H/L) ratio of Muscovy duck. The result indicated that E0C0, E400, E600, C400, C600, E200C200 and E300C300 had no significant difference in body weight, feed intake and feed conversion. There were significant effects on PCV, leucocyte count, percentage of heterophil and lymphocytes, but had no significant effect on eosinophil, monocyte and the H/L ratio. The C400 resulted a higher PCV count, percentage of heterophil, and H/L ratio. The C 600 produced the highest leucocyte count. In conclusion, the supplementation of ascorbic acid at 400 - 600 mg/kg feed ascorbic acid could improve theimmune profile, but could not improve the performance of Muscovy duck.

Abstract

The liver of female poultry has a vital role as an organ for biosynthesis of the yolk precursor and has a greater chance of experiencing cellular damages. This experiment was designed to study the uses of curcumin and monochromatic light in suppressing liver destruction during the period of yolk biosynthesis in Magelang ducks. One hundred and ninety two female Magelang ducks were assigned into a completely randomized design with a 4x4 factorial arrangement.  The first factor was dose of curcumin supplementation consisted of 4 levels i.e., 0, 9, 18, and 36 mg.  The second factor was the color of monochromatic light consisted of 4 levels i.e., white, red, green, and blue. The results showed that hydropic and fat degenerations in the livers of Magelang ducks entering laying phase were still in a normal range. There was an interaction effect between curcumin and monochromatic light on the serum SGPT/GOT and liver MDA concentrations (P<0.05). Serum lipid concentrations positively correlated with the increased serum SGPT/GOT and liver MDA concentrations as indicators of liver damages. Supplementation of curcumin and the use of monochromatic light could reduce and suppress liver destruction and damage during laying period.

Abstract

The objectives of present study were to formulate development strategies for dairy goat' farms that capable of supporting goat's milk agribusiness. Three medium scale dairy goat farms located in Bogor Regency which has population of more than 100 heads and has established more than 10 years were purposively selected for the study. Data were collected during February to May 2014. The design of this study was based on descriptive qualitative approach (rapid appraisal approach). Data were analized using internal factors evaluation (IFE) and external factors evaluation (EFE), strategic position and action evaluation (SPACE) matrix, and grand strategy matrix. It was revealed that dairy goat farms in Bogor Regency were located in quadrant I in SPACE matrix, which was on the aggressive strategy. Dairy goat farms have many resource advantages, despite facing various threats. The Grand Strategy Matrix analysis showed that dairy goat farms were in quadrant I. Dairy goat farms were in an excellent position to take advantage of the opportunities, overcome internal weaknesses and avoiding multiple external threats. The best strategies to be selected for dairy goat farms were market penetration and product development.

Abstract

The present study was conducted to evaluate the optimum level of dietary inclusion and the form of feeding sapu-sapu fish (SSF) as a single protein source for feed components of small holder Mojosari duck farming. A total of 180 twenty four wk-old laying ducks were fed with two forms (sun-dried and ground-fresh) and three levels of SSF (10, 20 and 30%) from 24 to 32 wk of age. Experimental diets were formulated containing 105.1; 141.5 and 177.9 g/kg crude protein and 3078; 3065 and 3052 kcal metabolizable energy (ME) /kg diet. Production performance and egg quality were measured. The form of SSF had a significant effect (P<0.0001) on feed intake, egg production, feed conversion, egg mass and egg number except final body weight. No significant effects (P>0.05) were found on all of the performance parameters measured due to feeding levels of SSF except feed intake and final body weight. The interaction of form and feeding level was significant (P<0.05) on egg and body weights. Low performance and egg quality were observed in the birds fed a diet containing the dried SSF. It can be suggested that local ducks required 20% SSF as a single protein source for maximum egg production (41.2%) and total egg number per wk (3.1 eggs/bird/wk) during 8 wk of rearing period. Egg quality can be improved by feeding the fresh SSF. However, due to be sufficiently better processing technique, the dried SSF would be potential to replace the common fish for laying ducks.
