“…Synchronizing the rate of N and energy release in the rumen for 24 h resulted in stable rumen condition and increased microbial efficiency (Fadel Elseed 2005). However Henning et al (1993) and Valkeners et al (2004) showed that rumen fermentation is not affected remarkably by an asynchronization of N and energy supply over a 48-h period.…”

“…A new diet evaluation system using protein balance in the rumen has been developed in the Netherlands (Tamminga et al 1994). Following these evaluation methods, several researchers had reported that the improvements in microbial metabolism due to upgrading rumen synchronicity resulted in greater improvements in animal performance (Sinclair et al 1993;Witt et al 1999;Fadel Elseed 2005;Mitani et al 2005), but some have disputed that ruminal synchronization between N and energy release improves microbial yield and animal performance (Kolver et al 1998;Kim et al 2000;Valkeners et al 2004). As described in the latest review on microbial synthesis by Dewhurst et al (2000), recent research into the synchronization efficacy has produced results confounded by factors such as intake response to experimental diets, dietary proportion of RDN and fermentable carbohydrates, rumen degradation kinetics with N and OM, fluctuation of both RDN and energy supply to rumen microbes in a specific feeding regimen including ruminal infusion procedures.…”

Two diets differing in their degrees of ruminal degradation synchronicity between nitrogen (N) and organic matter (OM) were fed to six adult rams at a maintenance level for three months in a two‐way layout design combining a randomized block design. Adaptive changes in microbial N (MBN) supply and N balance were investigated for both diets. The in situ rumen degradation parameters of OM and N were determined for four feeds and subsequently were used to formulate the two diets to have different ruminal degradation synchronicity and to be identical with metabolizable energy (ME), metabolizable protein (MP) and ruminally degradable N concentrations. The animals were divided into two groups and fed asynchronous (ASYNC) or synchronous (SYNC) diet, respectively. On days 30, 60 and 90 of each feeding period, a five‐day metabolism trial was carried out. Animals consumed their diets thoroughly and did not show marked body weight change during the observation. The apparent digestibility of OM and N did not differ significantly between the diets throughout the periods. The MBN supply was significantly greater for ASYNC than that for SYNC (P < 0.01) and was greater on days 60 and 90 than that on day 30 (P < 0.05). Neither diets nor periods had a significant effect on the efficiency of MBN synthesis. There was a significant period effect on N retention (P < 0.05) together with tendency of diet × period interactions (P = 0.1). There was no significant dietary effect. An improvement in N retention with advancing feeding period was observed for both diets. The plasma urea concentration decreased with feeding period (P < 0.01) and there was a concomitant decrease in urinary N excretion. Plasma glucose concentration tended to increase (P = 0.07). The results suggest that lengthening feeding duration from 30 days might have caused ameliorative changes in the utilization of ME and MP, and may have improved microbe synthesis irrespective of the degradation synchronicity.

“…Many researchers stated that using of high quality forage increased the production with low input cost. On the other hand, the higher amount of concentrates used in the Diet-AM caused the impaired energy protein synchronization which resulted low milk production (Lardy et al, 2004;Elseed, 2005;Schwab and Boucher, 2005).…”

The conventional diets have been fed to dairy cows since many years ago in Myanmar, however there is a little scientific information regarding the use of those diets as feed. Therefore, this study was conducted to evaluate the feeding values of conventional diets and their effects on the performances of dairy cows in Central Myanmar. Nine cross-bred Holstein Friesian cows (460±22kg) with the 12 th week of lactation were randomly allocated to one of three treatment groups with three replicates in a completely randomized design. The three treatments were Diet-ST (common diet from Sin Tel, Tatar U Township), Diet-MN (common diet from Myay Ngu, Tatar U Township) and Diet-AM (common diet from Amarapura Township). Cows were fed treatments for 60 days. The roughage to concentrate ratios ranged from 53:47 to 72:28 and the nutritive values were significantly different (p<0.05) each other. The highest nutrient intakes were observed in dairy cows fed on Diet-MN, however the nutrient digestibility were not different (p>0.05) except the CP and ether extract digestibility (CPD and EED). The nitrogen utilization was highest in dairy cows fed on Diet-ST and the lowest value was observed in the dairy cows fed on Diet-AM. Although the milk compositions were not different (p>0.05), the average milk yield of dairy cows offered the Diet-MN was significantly higher (p<0.05) than those of dairy cows fed on other diets. The highest total feed cost (p<0.05) was found in Diet-AM and the lowest value (p<0.05) was in Diet-MN. According to these findings, it was concluded that the highest feeding value was observed in Diet-MN and its effect on the performances of dairy cows was also greater than others. Moreover, it would be suggested that better bean residues and sesame residues could be used as fibre sources in the diets of dairy cows.

“…Pada ternak ruminansia dengan pemberian pakan berupa hijauan berkualitas rendah, maka penerapan sinkronisasi melalui penggunaan bahan pakan tambahan berupa sumber energi dan protein mampu memberikan pengaruh terhadap peningkatan sintesis protein mikroba (Lardy et al 2004;Elseed 2005;Hersom 2008).

ABSTRAKLimbah pertanian dapat digunakan sebagai sumber pakan berserat meskipun mempunyai keterbatasan karena mengandung protein kasar dan bahan organik terlarut yang rendah, serta serat kasar yang tinggi. Sinkronisasi nutrien melalui suplementasi dapat menghasilkan pengaruh positif pada sintesis protein mikroba terutama pada ternak ruminansia yang diberi pakan berupa hijauan berkualitas rendah. Kontribusi protein yang berasal dari mikroba rumen penting bagi produksi ternak pada manajemen pakan berbasis limbah pertanian. Protein mikroba mampu menyediakan 70-100% total protein tersedia bagi ternak pada pakan berkualitas rendah dan mempunyai profil asam amino yang sangat ideal untuk memenuhi kebutuhan ternak ruminansia. Makalah ini menguraikan tentang penerapan sinkronisasi suplai protein dan energi ke dalam rumen yang sudah dilakukan oleh beberapa negara. Penerapan sinkronisasi suplai protein dan energi ke dalam rumen di Indonesia masih terbatas pada: (1) Pengaturan penggunaan bahan pakan melalui imbangan hijauan dan konsentrat; (2) Suplementasi bahan pakan sumber protein dan energi; dan (3) Pengaturan frekuensi pemberian pakan. Penerapan sinkronisasi melalui penggunaan bahan pakan berdasarkan tingkat degradasi dan nilai indeksnya masih terbatas karena kurangnya ketersediaan data mengenai nilai degradasi protein dan energi bahan pakan yang digunakan di Indonesia. Oleh sebab itu, informasi nilai degradasi protein dan energi dari bahan-bahan pakan yang tersedia di Indonesia sangat diperlukan agar dapat mengoptimalkan penggunaan bahan pakan berkualitas rendah.

Synchronization of nutrients through supplementation can provide a positive effect on microbial protein synthesis, especially on ruminants fed low quality forage. Contribution of protein from rumen microbes is essential for feed management based on agricultural by product. Microbial protein can supply 70-100% of the total protein available for ruminants fed low quality feed. Microbial protein has amino acid profile which is ideal to meet ruminant's requirement. This paper describes synchronization of protein and energy supply in the rument that has been applied by several countries. Application of this synchronization in Indonesia is still limited on: (1) Arranging the use of feedstuffs through the ratio of forage and concentrate; (2) Supplementation of protein and energy sources; and 3) Feeding frequency regulation. The application of synchronization through the use of feed ingredients based on degradation level and its index value is still limited due to lack of data on protein and energy degradation of feed ingredients used in Indonesia. Therefore, the information on the degradation value of protein...
