Abstract

Research was aimed to determine nitrogen balance, microbial protein synthesis, and blood metabolites of male Bali cattle fattening fed ration with different protein level in smallholder farms North Central Timor, Province of East Timor Tenggara, Indonesia. The cattle used were 18 heads aged 2 to 2.5 years with initial body weight of 229.86±12.46 kg. The cattle were randomly divided into three treatment groups. The T0 group was given feed the same as traditional fattening cattle practices by farmers,T1 group fed ration containing 12% crude protein (CP) and 72% total digestible nutrients (TDN), andT2 group fedration containing 15% CP and 72%TDN. Cattle were fed individually for 90 days and drinkingwater ad libitum. The data were analyzedby analysis of variance.Results of research indicated the nitrogen balance, and blood urea nitrogen between T1 and T2 were relatively similar, but those were higher (P<0.05) than T0 . In contrast, microbial proteins synthesis, and blood glucose at 0, 4, and 6 hours before and after feeding were relatively similar between the groups. Blood glucose of T2 at 2 hours after intake were higher (P <0.05) than T0, but was not different with T1 . It can be concluded, that the fattening maleBali cattle fed ration containing 12% CP and 72% TDNimprovedthe nitrogen balance and blood metabolites, butit was no positive effect on the microbial proteins and N synthesis.

Abstract

This research was conducted at Claretian Benlutu dairy farm, Batu Putih District, TTS Regency for one month. This research consisted of 2 stages, namely 1 month of nipple dyeing and the second stage of testing the sample in the laboratory. The purpose of this study was to determine the effect of the use of garlic extract (Allium sativum) as a natural ingredient in the nipple on the microbiological quality of fresh cow's milk. In this study used 16 nipples from 4 dairy cattle. The experimental design used was a Completely Randomized Design of 4 treatments and 3 replications, with the treatment being R0 = commercial antisep solution as a control, R1 = concentration of garlic extract 20%, R2 = concentration of garlic extract 25% and R3 = concentration of onion extract white 30%. The variables observed in this study were reductase time and total bacteria. The results showed that the use of garlic extract (Allium Sativum) had the same effect as the commercial antisep solution seen from the time of bacterial and total bacterial reductase (P> 0.05). This is because garlic has anti-bacterial allicin which can inhibit bacterial growth. It can be concluded that garlic extract has the same ability as a commercial antisep solution in inhibiting the bacteria that causes mastitis in the nipples of dairy cows. Microbiological test results of 2 variables of milk use of garlic extract with a concentration of 20% are very optimal in the use of dairy milk nipple dyes in addition to inhibiting bacteria also saves costs in making garlic extract.

Abstract

This study aims to determine the effect of using different levels of thinner olive oil (extra virgin olive oil) on the viability and abnormality of spermatozoa and the pH of the semen of duroc pigs. The research took place in September 2020 in Noenebu, Tapenpah Village, Insana District, North Central Timor Regency, and the Laboratory of the Faculty of Agriculture, University of Timor. This study used a completely randomized design (CRD) with 4 treatments and 5 replications. Treatment R1 consist of 10% tris solution, 10% olive oil, 80% semen; R2 treatment consist of 15% tris solution, 15% olive oil, 70% semen; R3 treatment consist of 20% tris solution, 20% olive oil, 60% semen, and R4 treatment consist of 25% tris solution, 25% olive oil, 50% semen. The results showed that the effect of different treatments was very significant (P <0.01) on the viability of spermatozoa. The mean spermatozoa viability of each treatment was R1 of 89 ± 2.57%, R2 of 76.9 ± 12.51%, R3 of 62.8 ± 3.11%, and R4 treatment of 41.2 ± 15, 38%. The spermatozoa abnormalities were significantly different (P <0.05). Where the abnormality of the spermatozoa in treatment R1 was 8.8 ± 1.30%, R2 was 10.4 ± 1.67%, R3 was 11.6 ± 1.81%, and R4 was 14.4 ± 3.78%. The degree of acidity (pH) of the semen was not significantly different between treatments. The pH value of each treatment was R1 of 7.92 ± 0.83, R2 of 8.04 ± 0.54, R3 of 7.96 ± 0.39; and R4 treatment of 8.06 ± 0.64. It can be concluded that the addition of 10% to 20% olive oil can maintain the viability and abnormality of duroc boar male spermatozoa. However, the use of olive oil up to 20% does not affect to degree of acidity of the semen produced.

Abstract

The objective of research was to determine the effect of different protein levels on the carcass and meat characteristics of male Bali cattle fattened in smallholder farms. The cattle used were 18 heads aged 2 to 2.5 years with initial body weight of 229.86±12.46 kg. The experimental cattle were randomly divided into 3 treatment groups i.e., T₀, T₁, and T₂. The T₀ group cattle were fed ration according to traditional practices of fattening cattle by farmers (100% forage). The T₁ group cattle were fed ration with 12% CP and 72% TDN. The T₂ group cattle were fed ration with 15% CP and 72% TDN. The variables measured were final body weight and the characteristics of the carcass (meat, fat, and ratio of meat to bone), and meat quality including the chemical composition of the meat (protein, fat, and collagen), meat tenderness, cooking loss, water holding capacity, and degree of acidity (pH). Data were analyzed by variance analysis. Results of research showed that the final body weight, and weight of carcass, meat, and fat of T₁ and T₂ groups were similar; conversely, those parameters in T₀ group cattle were lower (P<0.05) that those in T₁ and T₂ groups cattle. The meat protein content of T₁ and T₀ groups cattle were similar; conversely, T₂ group cattle had lower (P<0.05) meat protein content compared to T₁ and T₀ groups cattle.  Fat content of T₁ group of cattle was higher (P<0.05) than that of T₀ group; while moisture contents and cooking losses of T₀ group cattle were higher (P<0.05) compared to those of T1 and T₂ groups cattle. Collagen content of meat in T₁ group cattle was higher than (P<0.05) that in T₀ group cattle, but T₂ group cattle had similar meat collagen content to T₁ and T₀ groups cattle. Meat tenderness of T₁ group cattle was higher (P<0.05) compared to those of T₀ and T₂ group cattle. It is concluded that the male Bali cattle fed ration with 12% CP and 72% TDN can increase the carcass characteristics and meat quality. This proves that the productivity of male Bali cattle can be increased when fed ration with adequate protein with a balanced energy content.
