  Four, lactating dairy cows were randomly assigned according to a 2x2 Factorial arrangement in a 4x4 Latin square design to study supplementation of malate level at 500 and 1,000 g and cassava hay in high-quality feed block. The treatments were as follows: T1 = supplementation of high-quality feed block without cassava hay + malate at 500 g; T2 = supplementation of high-quality feed block without cassava hay + malate at 1,000 g; T3 = supplementation of high-quality feed block with cassava hay + malate at 500 g; T4 = supplementation of high-quality feed block with cassava hay + malate at 1,000 g, respectively. The cows were offered the treatment concentrate at a ratio to milk yield at 1:2 and urea-treated rice straw was fed ad libitum. The results have revealed that rumen fermentation and blood metabolites were similar for all treatments. The populations of protozoa and fungal zoospores were significantly different as affected by malate level and cassava hay supplementation. In conclusion, the combined use of cassava hay and malate at 1,000 g in high-quality feed block with concentrates containing high levels of cassava chip at 65% DM could highest improved rumen ecology and nutrients digestibility in lactating dairy cows.

  Ten, one year old male cattles with initial body weight of 150±10 kg were randomly divided into 2 groups and received concentrate at 14% CP (T1) and Yeast-Malate Fermented Cassava Chip (YMFCC) (T2). The cows were offered the treatment concentrate at 1 %BW and urea-treated rice straw was fed ad libitum. Means were compared using t-test. All animals were kept in individual pens and received free access to water. The results have revealed that replacement of YMFCC on feed intake was non-significantly different, while Average Daily Gain (ADG) and digestibility of nutrients were higher (p<0.05) in cattle fed YMFCC (T2) treatments than received concentrate at 14% CP (T1) (235 and 203 g/d). In addition, the ruminal pH, ammonia-nitrogen and blood urea nitrogen concentration were significantly different (p<0.05). The concentration of volatile fatty acid was significantly different especially the concentration of propionic acid was slightly higher in cattle receiving T2 than T1 (23.9 and 17.8 mol/100 mol). Supplementation of YMFCC (T2) could improve population of bacteria and fungal zoospore, but decreased populations of Holotrich and Entodiniomorph protozoa in rumen (p<0.05). The results indicate that supplementation of Yeast-Malate Fermented Cassava Chip (YMFCC) as a replacement concentrate at 14% CP could improve rumen fermentation efficiency and digestibility of nutrients in cattle.

  Ten, one-year old heifers with initial body weight at 150±10 kg were randomly divided into 2 groups according to receive concentrate at 14% CP (1 kg/head/day) + Ivermectin (T1), cassava hay (T2) (1 kg/head/ day) and means were compared using t-test. All animals were grazing on ruzi grass pasture. The results have revealed that supplementation of cassava hay as anthelmintics replace ivermectin was non significant affected to fecal parasitic egg counts and average daily gain in buffaloes grazing on ruzi grass pasture (p>0.05). In addition, fecal parasitic egg counts dramatically declined for both treatment groups with 60.5 and 50.6%, respectively. However, Average Daily Gain (ADG) tended to be higher in swamp buffaloes fed on groups cassava hay (T2) treatments than in those fed concentrate + ivermectin. However, digestion of coefficients of nutrients particularly organic matter was significantly higher in T2 than those in T1. It was, hence concluded that cassava hay could not only provide as a protein source but also high efficiency serve as an anthelmintics in heifer.

  Six, one-year old male swamp buffaloes with initial body weight at 200±10 kg were randomly divided into two groups according to receive concentrate at 14% CP (1 kg/head/day) + Ivermectin (T1); cassava hay (T2) (1 kg/head/day) and means were compared using t-test. All animals were grazing on ruzi grass pasture. The results have revealed that supplementation of cassava hay as anthelmintics replace ivermectin was non significant affected to fecal parasitic egg counts and average daily gain in buffaloes grazing on ruzi grass pasture (p>0.05). In addition, fecal parasitic egg counts dramatically declined for both treatment groups with 64.8 and 57.4%, respectively. However, Average Daily Gain (ADG) tended to be higher in swamp buffaloes fed on groups cassava hay (T2) treatments than in those fed concentrate + ivermectin. However, digestion of coefficients of nutrients particularly organic matter was significantly higher in T2 than those in T1. It was, hence concluded that cassava hay could not only provide as a protein source but also high efficiency serve as an anthelmintics in swam buffaloes.

  Four, lactating dairy cows were randomly assigned according to a 2x2 Factorial arrangement in a 4x4 Latin square design to study supplementation of concentrate containing different level of protein at 14 and 18% CP and urea-treated corn silage at 2 and 5% respectively. The treatments were as follows by concentrate containing protein at 14% CP + 2% urea-treated corn silage (T1); concentrate containing protein at 14% CP + 5% urea-treated corn silage (T2); concentrate containing protein at 18% CP + 2% urea-treated corn silage (T3) and concentrate containing protein at 18% CP + 5% urea-treated corn silage (T4), respectively. The animals were offered the treatment concentrate at a ratio to milk yields at 1:2 and urea-treated corn silage were fed ad libitum. The results have revealed that total DM intake (%BW) and ruminal pH were not affected (p>0.05). Likewise, the concentration of ammonia-nitrogen (NH3-N) and Blood Urea Nitrogen (BUN) were significantly different affected by protein levels in concentrate with urea levels treated corn silage. In addition, rumen microorganism populations such as bacteria, protozoa and fungal zoospores were affected (p<0.05) by different by protein levels in concentrate with urea level treated corn silage. Moreover, the differences of protein levels in concentrate and urea level treated in corn silage were affected to milk yield and composition (p<0.05), especially income over feed highest in dairy cows were received a concentrate containing protein at 18% CP + 5% urea treated corn silage (T4). Therefore, results from this experiment indicated that the differences of protein levels in concentrate and urea level treated corn silage affected on rumen ecology and milk production in lactating dairy cows.

  Ten, one year old of native cattle with initial body weight of 150 ± 10 kg were randomly divided into two groups and received concentrate at 14% CP (T1) and Yeast Fermented Cassava Chip (YFCC) (T2). The cows were offered the treatment concentrate at 1% BW and ruzi grass was fed ad libitum. Means were compared using T-test. All animals were kept in individual pens and received free access to water. The results have revealed that replacement of YFCC on feed intake was non-significantly different, while Average Daily Gain (ADG) was higher (p<0.05) in native cattle fed YFCC (T2) treatments than received concentrate at 14% CP (T1) (259 and 205 g/d). In addition, the ruminal pH, ammonia-nitrogen and blood urea nitrogen concentration were significantly different (p<0.05). Supplementation of YFCC (T2) could improve population of bacteria and fungal zoospore, but decreased populations of Holotrich and Entodiniomorph protozoa in rumen (p<0.05).

  Four, one-year old of dairy heifers, weighing at 200±10 kg were selected. Cows were randomly assigned according to a 4 x 4 Latin square design to study supplementation levels of Yeast Fermented Cassava Chip (YFCC) replaced concentrate on rumen ecology, cost production and average daily gain. The dietary treatments were as follows: T1 = supplementation of concentrate: YFCC ratio at 100:0; T2 = supplementation of concentrate:YFCC ratio at 75:25; T3 = supplementation of concentrate:YFCC ratio at 50:50; T4 = supplementation of concentrate:YFCC ratio at 25:75, respectively. The animals were offered the treatment concentrate at 1.5 %BW and rice straw was fed ad libitum. The results have revealed that feed intake and average daily gain cost productions were significantly different among treatments especially affected the rice straw intake and average daily gain were higher in dairy heifers receiving T3 than T4, T2 and T1. In contrast, the cost productions was lower in dairy heifers receiving T3 than T4, T2 and T1. However, the rumen fermentation and blood metabolites were similar for all treatments. The populations of protozoa and fungal zoospores were significantly different as affected by levels of yeast fermented cassava chip supplementation. These results suggest that supplementation of yeast fermented cassava chip could highest replace at 75% of concentrate in dairy heifers.

  The objectives of this study was to evaluate the influence supplementation levels of Yeast-Malate Fermented Cassava Pulp (YMFCP) replace soybean meal in concentrate on feed-intake, Average Dairy Gain (ADG), rumen ecology and blood metabolites in crossbred native cattle. Five, two years of female crossbred native cattles weighing at 250±10 kg were randomly assigned according to a 5 x 5 Latin square design. The dietary treatments were as follows: T1 = supplementation of YMFCP replace soybean ratio at 0:100%; T2 = supplementation of YMFCP replace soybean ratio at 25:75%; T3 = supplementation of YMFCP replace soybean ratio at 50:50%; T4 = supplementation of YMFCP replace soybean ratio at 75:25%, T5 = supplementation of YMFCP replace soybean ratio at 100:0%, respectively. The cows were offered the treatment concentrate at 1.0%BW. All cows were fed ad libitum of rice straw with water and a mineral salt block. The results have revealed that rumen fermentation, blood metabolites and average daily gain were significantly different for all treatments. The populations of protozoa and fungal zoospores were significantly different as affected by supplementation levels of Yeast-Malate Fermented Cassava Pulp (YMFCP) replace soybean meal in concentrate. Moreover, supplementation levels of Yeast-Malate Fermented Cassava Pulp (YMFCP) replace soybean meal ratio at 50:50% in concentrate with rice straw as roughage source could highest improved ruminal fermentation efficiency, average daily gain including increase populations of bacteria and fungi zoospores, but decreased protozoal populations in rumen of crossbred native cattle.

  This experiment aimed to study the effects of rumen undegradable protein levels on productive performance of Thai Native-Brahman beef cattle. Four yearling Thai Native x Brahman beef cattle with an average Body Weight (BW) of 175.5±18.6 kg were used in a 4 x 4 Latin square arrangement. The treatments were levels of Rumen Undegradable Protein (RUP) in concentrate at 30, 35, 40 and 45%. Concentrates were formulated to contain 14% CP and were fed at 2.0% BW. The results showed that the DM intake, OM digestibility and TVFA increased linearly (p<0.05) while the level of RUP increased. Moreover, the ruminal NH3-N (p<0.01) and BUN linearly decreased, whereas at 45% RUP the ruminal NH3-N concentration increased (quadratically, p<0.01). The bacteria and protozoa populations also increased as the level of RUP increased. However, the bacteria and protozoa populations decreased quadratically (p<0.05) when the level of RUP changed from 40 to 45%. The N retention (g/d) tended to increase with increasing the level of RUP. However, the N retention tended to decrease at the level of 45% RUP. It could be concluded that RUP level at 40% in concentrate had positive effects on productive performances.

  Nine, two-years old of crossbred native cattle were used to examine the effects of supplementation levels of palm oil in yeast culture fermented cassava pulp on rumen fermentation and average daily gain. The cows were randomly allocated in a complete randomized design and three replicates (animals) per treatment. The first group (control) was fed on a yeast fermented cassava pulp without palm oil (YFCP0), The second group was fed yeast fermented cassava pulp + palm oil at 1% (YFCP1)and third groups was fed yeast fermented cassava pulp + palm oil at 2% (YFCP2), respectively. The cows were offered the treatment diets at 2%BW and rice straw was fed ad libitum. The results have revealed that supplementation of dietary treatment on feed intake, ruminal pH, ammonia-nitrogen and blood urea nitrogen concentration were non-significantly different, while Average Daily Gain (ADG) and cost production were significantly different and had highest in cattle receiving YFCP2 than those fed YFCP1, YFCP0 diets (633.1, 614.5 and 511.1 g/day of ADG and 0.92, 0.81, 0.73 US$/kgBW of cost production, respectively). The populations of bacteria and fungal zoospores were significantly different as affected by levels of palm oil supplementation. Especially, supplementation of YFCP2 in cattle had highest increase populations of bacteria and fungi zoospore than those fed YFCP1 and YFCP0 but decreased protozoal populations. Therefore, supplementation levels of palm oil at 2% in Yeast Culture Fermented Cassava Pulp (YFCP1) as supplement diets with rice straw as roughage source could highest improved ruminal fermentation efficiency, average daily gain including increase populations of bacteria and fungi zoospores, but decreased protozoal populations in rumen of crossbred native cattle.

  Ten, two-years old of crossbred native cattle weighing about at 250±20 kg were randomly divided into two groups according to receive two groups of supplemental dietary treatments by receiving YFCP1 + YFCP2 (T1) and YFCRR + YFDH (T2). The cows were offered the treatment diets at 2%BW and rice straw was fed ad libitum. Means were compared using pair t-test. All animals were kept in individual pens and received free access to water. The results have revealed that supplementation of dietary treatment on feed intake was non-significantly different, while average daily gain (ADG) and rumen microorganisms especially bacteria and fungi zoospores were significant different and cattle in heifer fed YFCRR + YFDH (T2) treatments and received YFCP1 + YFCP2 (T1) (646.4 and 533.2 g/d). In addition, the ruminal pH, ammonia-nitrogen and blood urea nitrogen concentration were non-significantly different. Supplementation of T2 could improve population of bacteria and fungal zoospore higher than those fed T1, but decreased populations of Holotrich and Entodiniomorph protozoa in rumen. The results indicate that supplementation of yeast fermented cassava and durian hull as supplement diets with rice straw as roughage source could improve ruminal fermentation efficiency, average daily gain in crossbred native cattle.
