Abstract

The objective of this study was to estimate potential genetic of Friesian Holstein at Taurus Dairy Farm, Cicurug, Sukabumi. Data observed were secondary data of milk yield, calving interval, service per conception, age at first calving, and length of lactation records of cows that have been experiencing one or more lactation since year 2003 to 2009, then were standardized based on milk yield by using correction factor 305 days of lactation period and mature equivalent (ME). Production trait (milk yield), reproduction traits (CI, S/C, length of lactation, and age at first calving) were analyzed by descriptive statistic. Data were analyzed by paternal half-sib correlation and nested method to get heritability, while the repeatability value were obtained by interclass and intraclass correlation method. Heritability and repeatability value then was used to count most probable producing ability (MPPA) and estimated real producing ability value and estimated transmitting ability (ETA) and breeding value (NP) of dairy cows. Estimates of heritability of milk yield by using nested are 0.287±0.135 (h2s), 0.310±0.154 (h2d), and 0.299±0.103 (h2(d+s)), and paternal half-sib correlation method was 0.63±0.23. Estimates of CI heritability with paternal half-sib method was 0.46±0.23, and values obtained using nested were 0.038±0.106 (h2s), 0.733±0.231 (h2d), 0.385±0.117 (h2(d+s)). Estimated heritability of S/Cwith paternal half-sib method was 0.001±0.110 and using nested method are -0.022±0.043 (h2s), 0.098±0.133 (h2d), 0.038±0.072 (h2(d+s)). Estimated value of milk yield repeatability with interclass correlation was 0.43±0.1 and intraclass correlation was 0.15±0.05. CI repeatability value with interclass correlation method was 0.00±0.09 and intraclass correlation was 0.19±0.07. S/C repeatability value with interclass correlation method was 0.12±0.15 and intraclass correlation was 0.02±0.05. Based on the calculation, the highest five ranks on the estimated relative value of MPPA and ERPA from 147 holstein friesian dairy cows with interclass repeatability method and 279 Friesian Holsteindairycows with intraclass method were 1966, 1941, 2180, 2087, and 2248. Database, Kimball, Beam, Doeboy, Paul, Varlour and Cassela get the highest rank, based on the estimated value of ETA and NP for 40 bulls using paternal half-sib heritability method and 38 bulls using nested heritability method.(Keywords: Friesian Holstein dairy cows, Milk yield, Reproduction traits, Genetic parameter)

Abstract

The aims of the study was to analyze the phenotype of Ongole Grade, SIMPO, and LIMPO cows based on the exterior characteristics and body size of cattle, and to distinguish the phenotype of the first filial (F1) and the backcross(BC1) of SIMPO and LIMPO cows, reared by farmers at Pacitan, East Java. The study was conducted with purposive sampling method, involving 5 districts: Pacitan, Arjosari, Pringkuku, Nawangan, and Punung. Eighty four farmers asrespondents with total of 100 head cattle were used in the study. The results showed that the dominant coat color in Ongole Grade was white. However, none of crossbreed in F1 and BC1 had white color, but the color phenotype changeto brown and dark brown, which increase the dark intensity. The muzzle color of Ongole Grade was black, and changed to red in BC1. The hoof color’s of Ongole Grade was black, and brown for BC1. The color phenotype of F1 was similarto both color of Ongole Grade and BC1 phenotype. The increasing intensity of coat color in F1 to BC1 indicated that there was a combination of gene from Simmental or Limousin with F1 and BC1which containing of two or several set ofgenes. SIMPO and LIMPO cows had greater body size than those of Ongole Grade cows. The body’s sizes of BC1 was larger than F1 in SIMPO and LIMPO cows, which was influenced by increasing the effect of additive genes from F1 toBC1.(Keywords: Ongole Grade, SIMPO, LIMPO, First filial, Backcross, Phenotype of cattle)

Abstract

his research aims to determine the physical characteristics and quality of eggs of mountain Maleo bird (Aepypodius arfakianus) in Papua and to determine hatching rate by using some modified hatching method to improvethe egg’s hatchability. This research used observation method to analyze variable egg hatching, temperature and humidity. There were three experiments of hatching method, which were semi-natural hatching outside of the habitat(ex-situ), hatching by using soil and serasah as the media, and hatching by using electric shelves as the media. Observation data of natural hatching showed that the temperature inside of the nest was about 30-35oC with humidityof 70-90%. The variables measured were embryo durability or fertility, hatchability, period of incubation, hatch weight, and embryo mortality. The data were analyzed using descriptive statistics and correlations for some data required and was presented as mean values and standard deviation (SD). Hatching using electric shelves as the media showed the best result. Length of incubation, egg fertility, hatchability, embryo mortality and hatch weight were 40.14±0.69 days,90.00%, 77.78%, 22.22%, 112.94±7.84 g, respectively; those of ex-situ modification were 47.50±0.71 days, 80%, 25%, 75%, 109.05±2.33 g, respectively; and those of soil and serasah media were 41.33±0.58 days, 90%, 33.33%, 66.67%, 113.33±5.05 g, respectively. Hatching modifications using electric shelves improves the quality of hatching, shorten theperiod of incubation, and reduced the mortality.(Keywords: Mountain Maleo (Aepypodius arfakianus), Hatching modification, Hatchability)

Abstract

The aim of this study was to evaluate performance and in vitro digestibility of Guinea grass grown on saline soil. Yield, quality, and in vitro digestibility of Guinea grass cultivated on coastal area with crop populations of 10,000,20,000, and 30,000 plants per hectare. Experiment was conducted following randomized complete block design (RCBD). Higher crop population increased fresh and DM biomass production, crude protein (CP) yield, dry matter(DM) content, neutral detergent fiber (NDF), lignin, and hemicellulose content, but decreased CP content, and in vitro organic matter digestibility (OMD). The increased population had no effect on acid detergent fiber (ADF) and in vitrodry matter digestibility (DMD). It could be concluded that guinea grass was recommended to be planted in saline coastal area by addition of fertilizer 20 tons/ha manure, 3 tons/ha gypsum, and 50 kg N (239 kg ZA/ha) as source ofnitrogen.(Keywords: Forage, Salinity, Saline soil, Manure, Gypsum, Nitrogen source)

Abstract

The experiment was conducted to study the effect of stuff feeding given during 22 to 28 days of ages on growth, meat fat and abdominal fat of broiler. Ninety broiler males (J) and 90 broiler females (B) were divided into 6 treatments groups with 3 replications of 10 broiler chickens each. The treatment were control (K) chicken which was fed with commercial diets from DOC to 42 days of age, DJ and P chickens were fed with corn bran (DJ) or pollard (P) from 22 to 28 days and continued with commercial feeding until 42 days. Feeds for DJ and P treatment was supplemented with B-12 mineral. Data collected were body weight, feed consumption, feed conversion, carcass weight, meat as well as abdominal fat. The data were analyzed by analysis split-plot design (3 feed treatments, 2 sex treatments and 3 phases) and then were tested by DMRT. The results showed that the feed treatments (K, DJ, and P) significantly affected (P<0.05) the body weight (1583, 1289, and 1213 g), feed consumption (1180, 1051, and 1035 g), feed conversion (1.67; 2.62; and -1.89), percentage of abdominal fat (1.80, 2.03, and 1.29%). Sex (J and B) significantly influenced (P<0.05) on body weight, feed conversion, percentage of abdominal fat, but feed consumption, percentage of carcass, meat fat, had no significant differences. The interaction of sex and feed showed significant influence (P<0.05) on meat fat at 22 day of ages. The interaction of feed, sex, and phase had significant influence (P<0.05) on body weight and feed consumption. It could be concluded that stuff feeding decreased body weight, feed consumption, percentage of abdominal fat, but increased feed conversion and meat fat.(Key words: Broiler chicken, Sex, Feed stuff, Broiler Starter, Corn bran, Pollard)

Abstract

The objective of the experiment study was to determine the effect of canary shell liquid smoke on the chemical, physical and sensory qualities of beef stored at room temperature. Beef samples were dipped in liquid smoke solutionwith the concentration of 0, 4, 8, and 12% (v/v) during 15 minutes and then stored for 0,2, and 4 days at room temperature. Each treatment was carried out three times and the variables measured were water, phenol and acidcontent, pH, water-holding capacity, cooking loss and sensory properties of samples. Data on chemical and physical qualities were analyzed using analysis of variance (Completely Randomized Design/CRD) with factorial 4x3. Thesensory properties were analyzed by a non parametric h-test. The results showed that liquid smoke concentration up to 12% significantly (p<0.05) increased water holding capacity and cooking loss of samples. Storage time up to four dayssignificantly (p<0.05) increased its pH value, cooking loss, whereas water-holding capacity was decreased. The meat sensory test showed that flavor and slimming rate were affected significantly (p<0.05) by liquid smoke. There was nointeraction between liquid smoke concentration and storage time. In conclusion, the addition of liquid smoke up to 12% increased phenol and acid content, while the physical quality of meat has decreased. Quality of beef stored up to 4 daysshowed a decreased of quality such as pH, water-holding capacity, cooking loss, and sensory meat.(Keywords: Canary shell, Liquid smoke, Storage time, Quality of beef)

Abstract

The study was aimed to identify and to analyze the strengths, weaknesses, opportunities and threats that facedthe city of Samarinda in fulfilling the egg need and to formulate the best and suitable strategy for the region to face theshortage of egg supply. The study was conducted in November 2009. The method used in the study was descriptive analysis method. Methods of data collection using questionnaires, interviews, observation and literature study. Methodsof data analysis using the SWOT analysis (strengths, weaknesses, opportunities, threats) were used to identify the internal environmental factors (strengths and weaknesses) and external environmental factors (opportunities and threats) areas. The result was then drawn in the quadrant analysis of SWOT and interpreted in the SWOT matrix could be to show the position and direction of regional development as well as alternative strategies that can be run. The results showed that internal identified value was 0.3922 and the external identified value was 0.0308. Development strategy at Samarinda in the first quadrant with a strengths was greater than the opportunities, so the region must be able to use these strengths to take advantage of existing opportunities. The area should implement an aggressive growth strategy (growth oriented strategy) in order to meet the self need of eggs in the region Samarinda.(Key word: Layer, Development strategy, SWOT analysis)

Abstract

The purposes of study was aimed to investigate the work ethics, motivations and innovative attitudes and its correlation with income of buffalo farmers in West Manggarai Regency. The surveys was conducted in December 2009until February 2010, involving 103 respondents chosen based on certain criteria. The relationships between work ethics, motivations and innovative attitude with the farmers income was analyzed using the chi-square, they are foundto have a significant correlation, and then continued by Phi test. The results showed that buffalo farmers in Lembor Subdistrict, West Manggarai regency, had a high working ethics, farming motivations and a positive innovativeattitude. The work ethics and innovative attitudes were not related to the income of buffalo farmers. The Breeding motivations had significantly correlated to income of buffalo breeder’s (X2count 14.934 > 3.84 X2table), meaning that thehigher breeding motivations, would bring effect to a higher income. The relationship between the variable of breeding motivations and the breeder’s income shows a medium (Phi coefficient = 0.381). The average income of respondents per livestock unit was Rp. 756,944 ± 221,542/year, while the average contribution from buffalo breeding activities for the household income, was 31.2%. This research implicated, that work ethics, and innovative attitudes, cannot be used to predict the farmers income, while breeding motivations, plays the role as a variable reliable to predict the farmers income.(Key words: Work ethics, Motivations, Innovative attitudes, Farmers income, Buffalo)
