“…Microbial synthesis in the rumen is incapable of providing sufficient protein to the high producing cows, and recommendation has been developed for undegraded intake protein or rumen undegraded protein (RUP) and high quality of essential amino acid profile of bypass protein (NRC, 2001). Because ruminal undegraded protein may increase the total amount of essential amino acid that is delivered to the small intestine and modify their profile (Calsamiglia et al, 1995;Calsamiglia et al, 2007;Ahari et al, 2011), adequate supply of protein to the small intestine of lactating dairy cows is essential for optimum milk production. Roseler et al (1993) and Kohn (2007) reported that the ration lease excess degraded protein in the rumen will have high endogenous urea concentration in blood, milk and urine.…”

Penelitian ini dilakukan untuk mengetahui dampak suplementasi energi dan protein seimbang dengan high rumen undegraded protein (HRUP) terhadap produksi dan kualitas susu pada sapi perah awal laktasi. Dua belas ekor sapi Friesian Holstein awal laktasi dibagi menjadi dua kelompok (kontrol dan HRUP). Kelompok kontrol dan HRUP memperoleh pakan basal dengan rasio hijauan dan konsentrat 60:40 (bahan kering), dengan konsentrasi rumen undegraded protein (RUP) masing-masing sebesar 27,47% (kontrol) dan 32,78% (HRUP). Pakan diberikan dua kali, pagi dan sore hari. Air minum diberikan secara ad libitum. Variabel yang diamati adalah konsumsi nutrien, produksi dan kualitas susu. Data yang diperoleh dianalisis dengan analisis t-test. Hasilnya menunjukkan bahwa konsumsi nutrien, produksi susu dan 4% FCM, produksi dan konsentrasi lemak dan laktosa susu, konsentrasi solid non-fat dan total solid susu antara kontrol dan HRUP tidak berbeda nyata (P>0,05). Namun, produksi dan konsentrasi protein susu antara kontrol dan HRUP menunjukkan nilai yang berbeda nyata (P<0,05). Disimpulkan bahwa suplementasi energi dan protein seimbang dengan HRUP pada sapi perah awal laktasi tidak memberikan dampak terhadap produksi susu dan 4% FCM, produksi dan konsentrasi lemak dan laktosa susu, solid non-fat dan total solid susu, namun memberikan dampak terhadap produksi dan konsentrasi protein susu pada sapi perah awal laktasi.

Objective. The aim of the study is to determine the effect of different plant essence oil supplementation to TMR, concentrate and hay on methanogenesis and at 2, 8 and 24 hours (h) using in vitro gas production technique in cattle. Material and methods. Three fistulated Holstein dairy cows were used for rumen fluid collection for application of in vitro gas production technique. Four essence oils (T. vulgaris, O. vulgare, S. aromaticum, Z. officinale) were used as plant extracts. Results. Essence oil supplementation, particularly at increased doses, significantly decreased methane production for TMR, concentrate and hay at 8 and 24 h compared to negative and positive control groups (p<0.05). Among all plant extracts, Syzygium 200 ppm supplementation resulted the lowest methane production values(p<0.05). While methane production at 24 h in positive control groups were recorded respectively as 10.45, 10.75 and 10.07 for TMR, concentrate and hay, the values in Syzygium 200 ppm group were recorded respectively as 1.65, 3.28 and 1.98 for these feed groups. Conclusions. The findings of the study indicate that increased doses of essence oil supplementation significantly decrease methane production in ruminants. Hence, it is suggested that essence oil will be highly beneficial in ruminant nutrition.
