Buffalo Moa is Indonesia's local livestock which is potentially maintained by the community on Moa Island as a source of family income and nutrition. This study aims to examine the marketing system, selling prices and factors that influence the price of buffalo at the farmer level. The results of the study found that the maintenance system was still traditionally carried out with two systems, namely semi-intensive during the rainy season and extensive during the dry season. The main motivation for raising livestock as a source of income, others as a means of payment for customary sanctions, family and religious events, marriage dowries. Buffalo cattle are marketed in the form of live animals and use intermediary traders. Weak market information so traders are more dominant in selling prices. Determination of the value of buffalo as a medium of exchange based on horn length and sex, the value of buffalo to be traded based on its performance, not defective, male sex at a higher price and the age range of 5–10 years, normal skin (not albino) is preferred Factors that influence the selling price at the breeder level are buffalo age, gender, skin color and climate.

This research has been carried out for a month using eighty three-month-old female Cihateup ducks and has been used to study the influence of glutathione on the endogen antioxidant response and histological illeum. The separation of glutathione was carried out using the distillation technique. Each experimental group consisted of 20 ducks, each treated with G0 = without glutathione; G1= Administration of glutathione 150 µL/head; G2 = Administration of glutathione 175 µL/head; G3= Administration of glutathione 175 µL/head. Tissue and blood sampling was collected at the end of the study by EDTA tube and a fixative solution, and tissue preparations were made using the Mallory-Asan technique and analyzed using a binocular microscope. Antioxidant levels were measured using a spectrophotometer technique based on the instructions of the Randox Kit. The results showed that glutathione affected (P<0.05) morphometric ileum (villi, Peyeri's plaque and goblet cells) and increased with increasing glutathione level and endogenous antioxidant response. It was concluded that glutathione is able to stimulate protein and lipid anabolism, as well as hormonal signals related to ileal tissue growth and antioxidants.

This research aimed to estimate the repeatability and MPPA values of Sapudi ewes based on the lamb’s daily gain from birth to pre-weaning and weaning. Using recorded data in a pedigree of lamb, 53 data with half-sib relationship came from 14 ewes which included the record of body weight gain of Sapudi lambs from birth to pre-weaning and weaning. The data were analyzed by descriptive method with a quantitative approach. The study showed that the average daily gain of pre-weaning and weaning was 007 kg/day. The repeatability value of pre-weaning and weaning daily gain was 0.636 in the high category and 0.377 in the medium category. The MPPA daily gain values for pre-weaning and weaning ranged from -0.032 to 0.018 and -0.016 to 0.009. The research concluded that the Sapudi sheep ewes based on the MPPA daily gain pre-weaning were six heads with four rankings, while the daily weight gain weaning was ten heads with ranking of five. The highest rank of Sapudi ewes in pre-weaning and weaning daily gain was ear tag 094 with MPPA values of 0.018 and 0.009. It is recommended that further research can be conducted to estimate the repeatability value of quantitative periodically as the basis for the selection and culling of livestock.

This study was conducted to determine and analyze the effect of differences in altitude levels on the macroclimate and microclimate in a closed house. This research was carried out at a closed house in the lowland, medium land, and highland with a length of 120 m and a width of 12 m. Observed data were made for 28 days at three times. Parameters observed include temperature, wind speed, humidity, and solar radiation. Macroclimate contribution to the microclimate was calculated based on the relationship's strength using correlation analysis and forming a regression equation. The results showed that the gift of macroclimate components to microclimate conditions in the form of temperature and humidity was more significant in the cages in the lowland and highland. In contrast, the contribution to wind speed was minimal. The predictor of air humidity in a cage in the lowland during the brooding phase was influenced by temperature, humidity, wind speed, and solar radiation; during the finisher phase, the temperature and humidity in the cage in the lowland were influenced by temperature, humidity, and solar radiation. This study concluded that the contribution of macroclimate factors to microclimate conditions in the brooding phase is more significant in the cage in the lowland. In comparison, in the finisher phase, the contribution is more important in the lowland and medium land.

This study was conducted to estimate the repeatability and MPPA values of Sapudi ewe based on birth weight and weaning weight. Samples used 93 Sapudi lambs from 26 ewes that lambed three times, and the observed variables were lambing weight and weaning weight. Collected data were analyzed quantitatively. Estimating repeatability by analyzing the variance of the relationship between sibling and the parental rank was based on the relative MPPA formula.. The results showed that the average lambing and weaning weights were 2.789±0.206 kg and 10.058±1.470 kg. The repeatability of lambing and weaning weight were 0.108±0.119, and 0.565±0.104 belonged to the low and high categories. The average MPPA of lambing and weaning weight were 0.001 and 0.087. MPPA values of lambing and weaning weight range from -0.087 to 0.075 and -1.721 to 2.713. The highest ranking of the Sapudi ewe in lambing and weaning weight is ear tag 103 and ear tag 27 with MPPA 0.075 and 2.713. It can be concluded that there were 11 ewes with MPPA lambing and weaning weight above the average MPPA population that should be maintained in the population.

The Payakumbuh region is an important tourist destination in West Sumatra. They produce various snack food made from cassava tubers, producing a large cassava peel as a by-product. The research aimed to study the meal yield rate, crude nutrient, fiber fraction, and mineral composition of cassava peels as by-products of cassava farm and snack food industries. Twenty cassava farms and ten snack food industries were visited, and the owners were interviewed for data on the type of cassava used, products, and handling of cassava peel. The quantity of cassava peel produced and potentially used as feed was recorded. Samples of fresh peels from three different varieties and tuber sizes were collected, weighed, dried, and ground in meal form to determine the meal yield rates and analyze for dry matter (DM) content, crude nutrient, fiber fraction, and mineral composition. Results found three cassava cultivars used to produce snack foods, i.e., black, bread, and sticky cassava. The percentage of fresh peel and meal yield rates ranged from 16.4-16.7% and 21.9-26.9%, respectively. DM and crude protein content varied between 23.8 to 27.0% and 9.3 to 11.2%, respectively. Bread cassava peels showed the highest DM, ash, and ADF content. Cassava peel contained considerably high Fe and was a good source of K, Mg, P, Na, Mn, and Zn.

Samples of fresh peels from three different varieties and tuber sizes were collected, weighed, dried, and ground in meal form to determine the meal yield rates and analyze for dry matter (DM) content, crude nutrient, fiber fraction, and mineral composition. Results found three cassava cultivars used to produce snack foods, i.e., black, bread, and sticky cassava. The percentage of fresh peel and meal yield rates ranged from 16.4-16.7% and 21.9-26.9%, respectively. DM and crude protein content varied between 23.8 to 27.0% and 9.3 to 11.2%, respectively. Bread cassava peels showed the highest DM, ash, and ADF content. Cassava peel contained considerably high Fe and was a good source of K, Mg, P, Na, Mn, and Zn.","PeriodicalId":33136,"journal":{"name":"Jurnal Sain Peternakan Indonesia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42335263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Flying fish are the fish that are widely found in the waters of the Makassar Strait, especially in Majene Regency. During the harvest season, flying fish leave a lot of waste that pollutes the environment. This research aimed to evaluate flying fish waste silage's physical and chemical qualities. The design used was a completely randomized design (CRD) with four treatments and four replications groups. To process the sample, formic acid at concentrations of 0%, 2.5%, 3%, and 3.5% was used. Anova was applied for data analysis, followed by Duncan's test if the treatments differed significantly. Parameters observed were chemical quality, including crude protein and fat content, total bacteria count, and pH, while physical-chemical quality included aroma, color, and texture of flying fish waste silage. The results showed that the addition of formic acid to fly fish silage had a significant effect (P < 0.05) on protein, fat, pH, and total bacteria levels but had no significant effect (P> 0.05) on the aroma, color, and texture of the hay. This research concludes that chemically processing flying fish silage with the addition of 2.5% formic acid can increase the protein content to the optimum level in the P1 treatment resulting in the highest protein content of 48.81% and the fat content of 1.63%, pH 3.5, total bacteria 4 x 104, sour taste, gray color and liquid texture that can be safely used as raw feed.
