Abstract

This study aims to determine the chemical and organoleptic quality of yoghurt made using different milk and yoghurt culture types. This research was carried out on January 2020. Located at the Faculty of Agriculture Laboratory of the University of Timor Kefamenanu (for organoleptic testing of yoghurt) and at the Faculty of Chemistry Laboratory Nusa Cendana Kupang Animal Husbandry (for testing pH, lactic acid levels, protein content and fat content). In this study using the 3 type of (fresh milk, UHT milk (Ultra High Temperature) and powdered milk), the experimental design used was a Completely Randomized Design (CRD) with 3treatments 3 replications so that there were 9 sample trial units. The treatment consisted of R0= Fresh milk, R1= UHT milk and R2= Milk powder. Based on the results of statistical analysis that the use of different types of milk showed significant or significant differences (P˂ 0,05). The use of fresh milk can give a good color of yoghurt that is equal to 1,77 which shows the yoghurt is yellowish white. The aroma of the best yoghurt is found in the UHT milk type which is 2,74 which shows the yoghurt is flavorful. The best yughurt texture is found in the type UHT milk that yoghurt is rather thick texture. The best acidity level of yoghurt is found in the UHT milk type which is 3,04 which shows that the yoghurt has acidic level, the good level of yoghurt preference is found in the type of milk powder of 2,37 which indicates that the yoghurt has a level of liking like. The best pH yoghurt in fresh milk is 4,35. The best level of lactic acid in milk powder is 0,78%. The best protein content in fresh milk is 2,86% and the best yoghurt fat content in the type of milk powder 0,30%. The conclusion of this study is the type of UHT milk is a type of milk that is better used in making yoghurt. When compared with the type of fresh milk and milk powder in terms of aroma, texture, acidity, Ph and protein content.

Abstract

The purpose of this study was to determine the effectiveness of nipple dip with mengkudu extact (Morinda citrifolia) on CMT test result. Mengkudu contains anti-bacterial substances, consisting of acubin, L. asperuloside, alizarin and some antraquinon substances that have been shown to show strength against pathogenic bacteria. This study used four Friesian Holstein (FH) cows which are known for sub-clinical mastitis and nipple dyeing solution from mature noni fruit. Nipple FH dipped using 30% concentration of noni fruit extract. After dyed, a Californian mastitis test (CMT) was performed. Based on the stastistic analysis of T-Test used, extract of noni fruit significantly (p <0,01) can inhibit bacteria cause mastitis. Noni fruit extract is able to inhibit the spread of bacteria that cause mastitis, thus lowering the risk of mastitis.

Abstract

This research was carried out in June 2020 at the Chemistry Laboratory of the Faculty of Animal Husbandry, Nusa Cendana University, Kupang for testing protein and fat levels. This study aims are to determine the protein and fat content of yoghurt made from various types of milk, the protein and fat content of yoghurt made from different amount cultures, and to determine the interaction between the type of milk and the number of yoghurt cultures. Research material in the form of fresh milk, UHT milk, yoghurt cultures. The design used in this study was a completely randomized design (CRD) with a factorial pattern using 2 treatment factors, namely factor A in the form of type of milk, which consisted of: A1 = fresh milk, A2 = UHT milk (Ultra High Temperature) and factor B in the form of culture. yoghurt consisting of: B1 = Lactobacillus bulgaricus and Streptococcus thermophilus, B2 = Lactobacillus acidophilus, Lactobacillus bulgaricus, and Streptococcus thermophilus, B3 = Streptococcus thermophilus, Lactobacillus adhophilus, Lactobacillus bulgaricus, and Bifidobacterium animals. From the two factors above, there were 6 treatment combinations consisting of: A1B1, A1B2, A1B3, A2B1, A2B2, A2B3, each combination consisting of 3 replications so that there were 18 experimental sample units. The results showed that the type of milk and the number of bacterial cultures affected the fat content and protein content of yoghurt and there was an interaction between the type of milk and the number of different cultures on the percentage of fat and protein content of yoghurt produced. types of milk with different culture brands had a significant effect (P<0.05) on the percentage of yoghurt fat content. The results of the follow-up test with Duncan's test showed that the combination of treatment between the type of UHT milk and the culture Lactobacillus bulgaricus had a significant effect (P<0.05) on the percentage of yoghurt protein content in all treatments. It can be concluded that fresh milk has higher protein and fat content than UHT milk. The number of cultures 2 (Lactobacillus bulgaricus and Streptococcus thermophilus) produced yoghurt with the highest fat content and protein content.

Abstract

This study aims to determine the effect of the sugarcane juice diluent in egg yolk citrate on viability, spermatozoa abnormality, and pH of Bali bull semen. This study has been carried out in Poultry Housing of Animal Science Study Program, and the Laboratory of the Faculty of Agriculture, University of Timor. Semen is collected from a a bull, ± 4.5 years old, in healthy condition. The method used in this study was a completely randomized design method with 5 treatments and 4 replications. The treatment giving are: T0 (diluent citrate-egg yolk without sugarcane juice); T1 (diluent citrate-egg yolk + 5ml sugarcane juice); T2 (diluent citrate-egg yolk + 10 ml sugarcane juice); T3 (diluent citrate-egg yolk + 15 ml sugarcane juice) and T4 (diluent citrate-yolk + sugar cane juice 20 ml). The variables measured were viability, abnormal spermatozoa, and semen pH of Bali bull. The results showed that T4 treatment with a 20 ml sugarcane juice level showed the best value for spermatozoa viability (92.875%), spermatozoa abnormality (6.375%), and semen pH (6.6). Conclusion: that the level of 20 ml of sugarcane juice in semen diluent can maintain the life of Bali bull spermatozoa.

Abstract

The study aimed to determine the carcass characteristics of local male pigs fed different energy sources. The research location is in Sasi Village, Kefamenanu District, North Central Timor Regency. The livestock used are 12 castrated local male pigs aged 12–16 weeks with a body weight range of 5–7 kg. The method used in the study is an experimental method using a completely randomised design (CRD) with 3 treatments and 4 replicates. The treatments tested were as follows: T1: 40% ground corn + 23% rice bran + 15% bran pollard + 22% fish meal; T2: 15% ground corn + 40% rice bran + 23% bran pollard + 22% fish meal; T3: ground corn 23% + rice bran 15% + pollard bran 40% + fish meal 22%. The variables observed in this study were slaughter weight, carcass weight, non-carcass weight, carcass percentage, and non-carcass percentage. The results showed that the treatments had no significant effect (P > 0.05) on slaughter weight, carcass weight, non-carcass weight, and carcass and non-carcass percentages of local male pigs in the growing phase. The slaughter weight for each treatment (T1, T2, and T3) was as follows: T1 was 6.867 kg, T2 was 7.936 kg, and T3 was 8.498 kg; the carcass weight for each treatment (T1, T2, and T3) was as follows: T1 was 3.466 kg, T2 at 4.115 kg, and T3 at 4.621 kg; the non-carcass weight for treatment T1 was 3.401 kg, T2 at 3.821 kg, and T3 at 3.886 kg; the carcass percentage for treatment T1 was 50.094%, T2 was 51.766%, and T3 was 52.674%; while the non-carcass percentages for treatments T1, T2, and T3 were 49.905%, 48.234%, and 47.325%, respectively.  It can be concluded that the use of ground corn, rice bran, or bran pollard as an energy source feed results in carcass and non-carcass production of local male pigs in the growing phase that are not significantly different, although there is a higher tendency when using 40% bran pollard in the diet.
