In Vitro Digestibilities of Six Rumen Protected Fat-Protein Supplement Formulas

Abstract . The aim of the research was to evaluate the efficacy of protection method of rumen protected fat-protein supplements. In vitro digestibility test was carried out to examine nutrients digestibility of different supplement formula based on the sources of protein and oil. The research used two sources of fat namely crude palm oil (CPO) and fish oil (FO) and three sources of protein namely milk skim, soy flour, and soybean meal. Thus there were 6 combinations that subjected in the in vitro digestibility test. The observed variables were the digestibility of dry matter (DM), organic matter (OM), crude fat (CF), and crude protein (CP). Results indicated that the method for protecting protein and fat was effective. This was showed by low nutrients digestibility in the rumen and high nutrients digestibility in the post rumen. In conclusion the combination between skim milk and CPO gave the best results among the other supplement formula.

Effect of Different Rumen Undegraded Protein Level on Feed Consumption, Nutrient Digestion, Body Weight and Body Condition Score in Early Lactating Dairy Cattle

The objective of this study was to determine effect of different rumen undegraded protein level on feed consumption, nutrient digestion, body weight and body condition score in early lactating dairy cattle. Ten Friesian Holstein cows were divided into two groups (five animals were used as control and another group as treatment object). Diets were forages and concentrates with ratio of 60:40, DM basis. The cows feed after parturition until 100 days of lactation. The control group concentrate diets containing Crude Protein (CP) 18.55%, Total Digestible Nutrient (TDN) 56.94% and Rumen Undegraded Protein (RUP) 5.10 CP%, while the treatment group concentrate diets containing Crude Protein (CP) 18.83%, Total Digestible Nutrient (TDN) 58,91% and Rumen Undegraded Protein (RUP) 6.17 CP%. Drinking water was given by ad libitum. The comparison results between the two conditions (control and treatment) were tested using independent t-test analysis. Results indicated that nutrient intake and digestion (dry matter, organic matter, crude protein, crude fibre and ether extract), body weight and body condition score were not significant. The conclusion is supplementation with different rumen undegraded protein level on early lactating dairy cattle could not increase feed consumption, nutrient digestion, body weight and body condition score.

Dairy Cows Productivity and Socio-Economic Profile of Dairy Smallholder’s Communities in Yogyakarta, Indonesia

The objective of this field questionnaire survey was to describe the dairy cow productivity and socio-economic profile of dairy cattle farmers in Daerah Istimewa Yogyakarta smallholder farming communities which have been targeted dairy development policy. The study was conducted on 190 Friesian Holstein (FH) cows maintained under smallholders management system in Daerah Istimewa Yogyakarta, Indonesia. A total of 83 farmers were randomly selected and interviewed with structured questionnaire to assess the socio-economic dairy farmer and productivity performance of dairy cows. The number of dairy productivity performance within the normal. Shortages as well as high cost of feed, occurrence of disease, scarce information about feeding and high medicament cost were the main constraints which might have contributed considerably to delayed age at first service, late age at first calving, long calving interval, short lactation length and low milk production. Therefore, strategies designed to solve the existing problem should be important by involving all stakeholders in the formulation and implementation of improvement strategiesor dairy development policy was being implemented and necessary respect to environmental factors affecting agricultural activities such as a constraint on land use and access to water resources.
