The material used was Day Old Duck of male Tegal duck  as much as 120 heads with experimental research methods and Completely Randomized Design (CRD). There were 6 treatments: feed without breadfruit leaf powder, feed + breadfruit flour 3% / kg feed, feed + breadfruit flour 6% / kg feed, feed + breadfruit flour 9% / kg feed, feed + flour breadfruit 12% / kg feed, and feed + breadfruit flour 15% / kg feed. Each treatment was repeated 5 times and each replication consisted of 4 ducks. The variables observed were the number of red blood cells, white blood cells, HDL, LDL, blood triglycerides, correlation between cholesterol, HDL and LDL blood with meat cholesterol of male Tegal duck of 10 weeks old.  The result of the analysis showed that the supplementation of breadfruit leaves has significant effect (P <0,05) on the number of red blood cells, white blood cells, HDL, and blood triglyceride. There is a positive correlation between blood cholesterol with duck meat cholesterol which given breadfruit leaf powder. This research can be concluded that the supplementation of breadfruit leaf powder (Artocarpus altilis) can increase the number of red blood cells, white blood cells, blood HDL level but lowers blood cholesterol and triglyceride blood of male Tegal duck of 10 weeks old. Cholesterol meat is affected by blood cholesterol with regression coefficient of 0.780941, influenced by LDL (r = 0.407849), but negatively affected by HDL (r = -0.47022)
Nutritive Value and the Quality of Ensiled Napier Grass (Pennisetum purpureum Schum.) and Banana (Musa acuminata) Peelings
Full text linkThis paper aimed to evaluate the nutritive value and the quality of ensiled Napier grass (Pennisetum purpureum Schum) and banana (Musa acuminate) peelings.  Different levels of banana peeling and Napier grass were used in this study.  The levels of Napier grass and banana peeling compared as treatments with four replications were as follows: 100% Napier Grass (NG), 75% (NG) + 25% Banana Peeling (BP), 50%NG + 50%BP, 25%NG + 75% BP and 100%BP. Napier grass and banana peeling were mixed based on the percentage combination as treatments, weighed and placed into empty jam bottle with weights ranging from 64.4 grams to 509.2 grams as a simulated laboratory silo. Samples were stored in eight weeks at the Dairy Training Research Institute. Proximate analyses were done at Animal Nutrition Laboratory Institute of Animal Science while ADF, NDF, IVDMD, and IVOMD were done at the Animal Nutrition Division Laboratory at Dairy Training and Research Institute, UP Los Baños. Physically, the color of silage were light yellow with a  little greenish color for 100% napier grass, light to moderately yellow for the  three combinations of napier and banana peel and  yellow for 100% banana peel. Texture ranged from dry and coarse for napier grass, relatively dry for the combinations and moderately wet for the banana peel. The napier grass had a slightly acidic smell, the combinations had slightly sweet, acidic smell while the 100% banana peel had a sweeter, acidic smell.  Likewise, pH before ensiling had ranged from 5.7 (25%NG + 75%BP) to 7.5 ( 100% BP) while after  ensiling the pH changed from 4.575  ( 100% napier grass) to 5.75 ( 100% banana peel ). There were significant differences on DM, Moisture, CP, EE, CF, and Ash before ensiling. Similar trend was observed after ensiling except the ash content of all the treatments. ADF and NDF did not show significant variations in all treatments. IVDMD and IVOMD before ensiling varied significantly, but after ensiling only IVDMD of the treatments differed significantly. In terms of physical attributes, nutritive value and digestibility, banana peel can be used as silage material. All treatments generated comparable acceptability when fed to the animal.  It is suggested that further study, specifically in vivo trial, will be conducted to validate the feeding and nutritional value of banana peel as alternative silage for ruminants
The Physicochemical and Sensory Qualities of Goat Cheese with Indigenous Probiotic Starter at Different Temperatures and Storage Durations
Full text linkThe research is conducted aiming at analyzing the physical, chemical, and sensory qualities of goat cheese with different temperatures and storage duration. The research materials are goat milk and L. plantarum TW14 and L rhamnosus TW2 isolates, and its equipments include a set of cheese production tools, colorimeter, and SEM. The variables analyzed are cheese’s physical quality (color and structure), chemical qualities (total titrated lactic acid) and sensory qualities (texture, flavor, aroma and likeness). The treatment consists of 2 factors, namely the first factor including: storage temperature (freezer and refrigerator) and the second factor: storage duration (0; 15; 30; 45 and 60 days) with 3 replicates. The obtained results indicate that storage temperature does not influence the cheese’s brightness level (L*), a* value (redness) and b* value (yellowness) and sensory qualities (texture, flavor, aroma and likeness), yet storage duration influences the cheese’s L* value (P0.05) on it. The cheese’s structure shows protein aggregate, void and lactic acid bacteria. The conclusion is that frozen-stored goat cheese still has good physical, chemical, and sensory qualities
Evaluation of two estrus synchronization protocols in dairy cattle at North Shoa zone Ethiopia
Full text linkThis study was initiated to change the hesitation of the farmer on the effectiveness of estrus synchronization under their (Ethiopian small holder) livestock management system using two synchronization protocols. Non-pregnant animals with normal reproductive tract and that fulfilled the preconditions for estrus synchronization were considered for treatment & assigned into two synchronization protocols (single PGF2α injection; and double PGF2α injection). Among 94 (27 heifer and 67 cows) synchronized cows using one and two injections of PGF2α protocols 26 heifers and 63 cows (89/94.7%) were exhibited estrus by visual observation and rectal palpation the remaining 5 (5.3%) did not illustrate heat. The overall pregnancy was 59.6 % with overall birth 94.3 %. High pregnancy was obtained in the double injection of PGF2α treatment group (63.1 %) than animals treated with one shot protocol 55.8 % there were statistically significant difference between treatments (p<0.05). Higher pregnancy was obtained from cross breed animals than local breeds. More over most of the animals come to estrus greater than 96 hrs. There was also significant difference between technicians on detecting the CL and conception. The estrus response, conception rate, pregnancy rate and calving rate was higher in both protocols so producers or farmers can use either the two protocols to achieve remarkable result but tight follow-ups and more resources are need to be exploited at farmer level
Physiological Response and Haematological Profile of Reproductive Ewe Consuming Diet Supplemented with Black Tea Extract and Sunflower Seed Oil
Full text linkThis study was aimed to examine the effect of black tea extract addition in diet containing 4% and 6% sunflower oil on ewe physiological responses and blood profiles from late pregnancy until early lactation. This study was designed using a 2×2 factorial completely randomized design with 5 replications on 20 late-pregnant ewes. The first factor was two levels of sunflower seed oil (4% and 6%) and the second factor was the levels of black tea extract addition (0 ppm and 500 ppm). Data were analyzed by using analysis of variance (ANOVA) and Duncan’s multiple range test. Results showed that supplementation of sunflower seed oil and black tea extract had no effect on physiological responses and blood profiles of ewe during late pregnancy until early lactation except for erythrocyte numbers. Erythrocyte numbers were higher on 6% sunflower seed oil supplementation than that of 4% (P<0.05). In conclusion, addition of black tea extract in diets containing 4% and 6% sunflower seed oil limitedly affect physiological responses and blood profiles of ewe
Genetic diversity and structure of domestic cavy (Cavia porcellus) populations from smallholder farms in southern Cameroon
Full text linkAlthough domestic cavies are widely used in sub-Saharan Africa as a source of meat and income, there are only a few studies of their population structure and genetic relatedness. This seminal study was designed with the main objective to assess the genetic diversity and determine the population structure of cavy populations from Cameroon to guide the development of a cavy improvement program. Sixteen microsatellite markers were used to genotype 109 individuals from five cavy populations (Wouri, Moungo and Nkongsamba in the Littoral region, and Mémé and Fako in the Southwest region of Cameroon). Twelve markers worked in the five populations with a total of 17 alleles identified, with a range of 2.9 to 4.0 alleles per locus. Observed heterozygosity (from 0.022 to 0.277) among populations was lower than expected heterozygosity (from 0.42 to 0.54). Inbreeding rates between individuals of the populations and between individuals in each population were 59.3% and 57.2%, respectively, against a moderate differentiation rate of 4.9%. All the tested loci deviated from Hardy-Weinberg equilibrium, except for locus 3. Genetic distances between populations were small (from 0.008 to 0.277), with a high rate of variability among individuals within each population (54.4%). Three distinct genetic groups were structured. This study has shown that microsatellites are useful for the genetic characterization of cavy populations in Cameroon and that the populations investigated have sufficient genetic diversity that can be used to be deployed as a basis for weight, prolificacy and disease resistance improvement. The genetic of diversity in Southern Cameroon is wide and constitute an opportunity for cavy breeding program.Â
Measurement of Phenotype Characteristics of Sasak Ducks: Indian Runner Ducks of Lombok Island Indonesia
Full text linkThis study was designed to determine the phenotype characteristics of Sasak ducks in Lombok Island. Â The study used 64 Sasak ducks at production stage which were kept intensively by small holder farmers. Observations on the characteristics of the feather color were carried out directly on each animal. The data observed were feather colors, beak color, and the color of the foot and shank, while the data on the size of the body that was observed were body weight, beak length, neck length, back length, breast circumference, back length, thigh length, shank length, and the distance between the two pubic bones. The data obtained were tabulated and analyzed descriptively. The study concluded that the characteristic of the color of feathers in Sasak ducks were dominated by Roman color (50.13%), followed by Tanak color (21.87%), Tongkak color (15.63%), Rombak color (6.25%), and Cemaning color (3.12%). Â Sasak ducks with medium size were observed to have a relatively long beak, medium-long neck, short back, broad and deep chest, medium height, and the distance between the two pubic bones was quite wide. These characteristics indicate that Sasak ducks are the type of superior Indian Runner having better production ability compared to the other types of Indian Runner duck.Â
Effect of Synbiotics Supplementation in Feed on Tegal Male Duck’s Internal Organs
Full text linkThe aim of this research was to review the application of synbiotics in duck feed towards its gastrointestinal and internal organs’ effectivity. The study was carried out to 60 two-months old drake. The feed given to the research subjects consisted of soybean meal, fishmeal, methionine, lysine (PT. CJeil Jedang Tbk. Indonesia), corn, bran, oil, premix, CaCO3 and synbiotics (Lactobacillus sp. and inulin prebiotics). The ratio of feed was based on isoprotein and isocalorie, with 19% of protein and 2900 kcal/kg of metabolic energy. The research was under a fully randomized in vivo experimental method with 4 treatments and 5 replicates, using 3 drakes each. These treatments were R0: controlled feed, with 0% of synbiotics; R1: feed with 2% of synbiotics; R2: feed with 4% of synbiotics; and R3: feed with 6% of synbiotics. Data obtained were subject to analysis of variance. The results show that the use of synbiotics in feed does not have any significance on the weight and length of duodenum, jejunum, and ileum. It also does not have any significance on the weight of gall, pancreas, gizzard, liver and heart. In conclusion, feed with 6% or less of synbiotics can be used without affecting the physical condition of gastrointestinal (weight and length) and internal organ (weight
