The variables analyzed were milk production as the dependent variable (Y), and the independent variable (X) included forage feed, concentrate feed, lactation period, dry period, age of cows, age at first estrus, age at first calving, days open and service per conception. Data analysis was carried out descriptively and statistical analysis using multiple linear regression equations. The results showed that the factors that affect milk production, namely factors X1, X2, X3, X4, X5, X6, X7, X8, and X9 together had a significant effect (p<0.05) on milk production. Milk production performance can be influenced by independent factors by 60.1% while 39.9% is caused by other factors outside the study. It can be concluded that the factor that has a very strong influence on milk production is the lactation period, while the factor that has a low influence is the dry period
Effect of Heating Treatments on Nutritional and Antinutritional Contents of Flaxseed Flour (Linum usitatissimum) as Poultry Feed
No full textABSTRACT This research aimed to evaluate the effect of several heating treatments on the nutritional and antinutritional content of flaxseed flour as a poultry feed. Raw brown flaxseed was picked as the material. The method of this research was a laboratory analysis using a completely randomized design (CRD) with 5 treatments (T0: without heating as a control, T1: sand fried flaxseed, T2: steamed flaxseed, T3: autoclaved flaxseed, T4: microwaved flaxseed) and 5 replications. The variables observed were dry matter, crude protein, crude fat, crude fiber, ash, gross energy, tannin, and phytic acid. The data were analyzed by analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT). The result showed that several heating treatments had a highly significant effect (p<0.01) on all of the variables observed. Heating treatments given to the flaxseed flour showed a general reduction trend to the nutritional and antinutritional content at different rates, but the losses in antinutritional content of microwaved flaxseed flour were higher than the other treatments. It concluded that microwaved flaxseed gives the best results to be used as poultry feed.Keywords: antinutrient factor, flaxseed, heat treatment, nutrient valu
The Improvement Genetic Quality Of Muscovy Ducks: Review
No full textIndonesia has the potential of muscovy duck resources with various characteristics and qualities that are spread throughout the region. muscovy duck has a larger body size than ducks but has a weakness in terms of lower egg production. To produce ducks with high body weight and egg production, Indonesian breeders often cross muscovy ducks with ducks. The use of a cross model with 4-crossbreeding is an efficient strategy, but genetic improvements need to be made to the two parents including the muscovy duck and the ducks itself because, in some crosses, sterile hybrid results will be obtained. The use of artificial insemination can be done to support the crossing of offspring in obtaining the desired production results. Therefore, a recording should be made to determine the quality of the offspring either using natural marriage or with the help of artificial insemination and its effectiveness on fertility in the next few periods. The use of marker-assisted selection (MAS) can help in the selection to get superior mutton traits and to find out the metabolic pathways related to the formation of the desired body weight and liver weight.Keywords: genetic quality, 4-crossbreeding, muscovy duck, marker-assisted selection (MAS

The research was conducted in vitro. The treatment used was: P1 = Complete Feed (40% corn straw + 60% concentrate), P2 = Complete feed (40% corn straw + 60% concentrate + 0% calliandra leaf flour + myristic acid 30 g/kg DM, P3 = Complete feed (40% corn straw + 35% concentrate + 25% calliandra leaf flour + myristic acid 30 g/kg DM, P4 = Complete feed (40% corn straw + 30% concentrate + 30% calliandra leaf flour + myristic acid 30 g/kg DM, P5 = complete feed (40% corn straw + 25% concentrate + 35% calliandra leaf flour + myristic acid 30 g/kg DM. The variables of research were the nutritional content of DM, OM, CP, CF, EE, Ash, NDF, ADF, CPD, and NH3. The data obtained were analyzed using the Randomized Block Design (RBD) method consisting of 5 treatments and 3 repeats. If data shows a significant difference, proceed with Duncan Multiple Range Test (DMRT). The results showed a very significant difference in CPD increase and un significant difference in NH3 increase. The increase of NH3 was still normal amounts for rumen microbes’ growth. The conclusion of this research was the best treatment for P5 (complete feed 40% corn straw + 25% concentrate + 35% calliandra leaf flour + Myristic acid 30 g/kg DM), P5 could increase rumen fermentation products in vitro.Keywords: calliandra, myristic acid, in vitro, rumen fermentation product

No full textThis research aims to determine the appropriate substitution treatment of coconut milk with FiberCreme for beef rendang based on physical characteristics and organoleptic. The research material used was silverside beef, coconut milk, FiberCreme, and rendang seasoning. This research used a completely randomized design consisting of P0 (100% coconut milk), P1 (75% coconut milk:25% FiberCreme), P2 (50% coconut milk:50% FiberCreme), P3 (25% coconut milk:75% FiberCreme), P4 (100% FiberCreme) with 4 replications. Data analysis used analysis of variance (ANOVA), followed by Duncan's Multiple Range Test (DMRT) if the results showed significantly different or very significant effects. Parameters measured in this research were pH, color La*b*, and organoleptic (color, aroma, texture, taste, and overall acceptance). The ANOVA results showed that the substitution treatment of coconut milk with FiberCreme had no significant effect (P>0.05) on pH, the color of rendang a* (redness), and organoleptic rendang, but had a very significant effect (P<0.01) on the color of rendang L* (lightness) and b* (yellowness). It can be concluded that the substitution of FiberCreme up to 100% did not have a negative effect, so rendang was generally accepted based on physical and organoleptic properties.Keywords: Beef rendang, coconut milk, FiberCreme, physical quality, organolepti

No full textABSTRACT
This study aims to determine the effect of Moringa leaf powder (Moringa oleifera Lamm) on concentrated feedstuff to improve the body weight, scrotal circumference, and semen production of kacang goat. A total of 20 male kacang goats aged 12-18 months with an average body weight of 15.96±1.82 kg have been used in this study. The feedstuff given is elephant grass (Pennisetum purpureum) as basal feed and concentrated feed substituted with Moringa leaf powder in isoprotein feed. This study uses a completely randomized design. The male kacang goats are divided into 4 treatment groups with different dose of Moringa leaf powder substitution in the concentrated feed, namely P0 = 0%, P1 = 10%, P2 = 20%, and P3 = 30%. Each treatment is repeated five times. The data are then analyzed by ANOVA. Analysis of the nutritional content of Moringa leaf powder substituted in concentrate feed includes DM content = 87. 98%; OM = 91.59%; CFb = 8.03%; CP = 27.73%; CF = 4.16%; NFE = 39.92%; ADF = 8.68%; NDF = 9.96%; Tannin = 29.64%; Saponin = 2.37%, GE = 3997.00 cal / g. The results show that substituting Moringa leaf powder in concentrated feed has a significantly different effect (P 0.05) on the amount of feed consumption and semen production. The study concludes that feeding with Moringa leaf powder by 20% as concentrate substitution is given 1% of body weight (based on Dry Matter) can be applied to increase body weight, scrotal circumference, and semen production of male kacang goats.

Physical Characteristics of Three Types of Muscles with Different Aging Duration
No full textThe demand for premium quality meat continues to grow along with changes in the lifestyle of the upper middle class community, the increasing number of tourists and expatriates from abroad. The premium meat must be imported from abroad to meet the needs of special markets such as hotels, restaurants and supermarkets. Some Indonesian cattle cannot produce meat that meets the premium quality criteria, especially tenderness. The hardness of the flesh can be overcome by aging. This study aims to determine the physical and microbiological quality of bali beef with different aging times. This study used bali cattle. The treatments were aging for 1, 21 and 42 days and three different muscle types (Longisimus dorsi, Gluteus medius and Semitendinosus). This study used a completely randomized design (CRD) with a 3 x 3 factorial pattern. If the data obtained were significantly different, it would be continued with the Least Square Means test. The results showed that the combination of aging treatment for 21 days and muscle type (Longisimus dorsi, Semitendinosus) showed the best and most efficient steak tenderness results.
