“…Soybean meal by treatment with formaldehyde would appear to be a potential method of decreasing rumen degradation of high quality protein and allowing more dietary protein by-pass the rumen to abomasum and lower digestive tract. Widyobroto et al (1995;2010) added that protein protection (by-pass) by formaldehyde addition or heating could increase the undegraded protein fraction of 50 to 80% and did not decrease its digestibility in the intestinum. Rumen Undegraded Protein (RUP) supplement based on the requirement of rumen microbes on nitrogen precursor has to be calculated to improve nutrient efficiency and milk production; and an increase in RUP level in the ration will increase the use of nutrients by dairy cows, although it also depends on the energy intake (Widyobroto et al, 2001).…”

Abstract: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.

This research was aimed to examine the effect of undegraded protein supplementation on nutrients intake, production and milk composition in dairy cows. The purpose of this research was to provide information on the undegraded protein supplementation to increase milk production and composition in dairy cows. The research was conducted for 3 months in Boyolali-Central Java. The study used 20 lactation cows (<3 months of lactation), aged 3 to 3.5 years with body weight from 350 to 400 kg. The cows were then randomly divided into 2 groups of ten based on their body weight, milk production, lactation period and age. The first group (control) and the second group (treated), both were fed diet based on NRC (1987). The second group was added undegraded protein (UDP) of 30 g/l milk that mixed by concentrate. The observed variables were dry matter intake (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), milk production and milk composition including fat, protein and solid non fat (SNF). Data obtained were examined by t-test. The results showed that intake of DM, OM, and the NDF of treated and control groups were not different (9.57; 8.49; 4.98 vs 9.44; 8.38; 5.40 kg/cow/d, respectively); however, protein intake of treated group was higher (P<0.01) than that of the control group (1097 vs. 1210g/cow/d). Milk production of cows receiving UDP supplementation tended to be higher than that in the control group (+ 1:45 kg/cow/d). Although they tended to be lower in fat (4.13 vs. 3.88%), protein (2.45 vs. 2.27%) and SNF (7.26 vs. 6.94%), but protein and fat production were higher for cows receiving UDP supplementation (366 each; 214 vs. 330; 196g/cow/d). It can be concluded that UDP supplementation increased milk, fat production and milk protein but it tended to reduce the level of fat, protein and SNF milk.
