The objective of the present study was to determine the effect of urea-lime treatment on nutritive value and rumen degradability of rice straw by using the nylon-bag technique. Straw was assigned to treatments according to a 2 × 3 × 5 factorial arrangement in a completely randomised design. Factor A comprised two storage times (10 and 20 days), Factor B comprised three levels of lime addition (0%, 1% and 2%) and Factor C comprised five levels of urea treatment (1%, 2%, 3%, 4% and 5%). Two ruminal fistulated beef steers (410 ± 10 kg) were used to determine in situ DM degradability. The results showed that increasing the urea treatment level increased crude protein and organic matter concentrations, while concentrations of neutral detergent fibre and acid detergent fibre decreased linearly with an increasing lime treatment level (P < 0.05). Moreover, urea and lime treatment increased the soluble fractions at time zero (a), insoluble degradability fractions (b), rate of degradation (c), potential degradability (a+b) and the effective degradability of DM (P < 0.05). Furthermore, rice-straw treatment at 20 days showed a better straw chemical composition and rumen degradability (P < 0.05) than that at 10 days. In conclusion, treatment with urea and lime improved the quality and ruminal degradability of rice straw. The present study suggested that urea treatment can improve the nutritional value of rice straw, especially, treatment with 3% urea together with 2% lime.

The current study was aimed to determine the effect of rambutan peel powder (RPP) supplementation on in vitro gas production, rumen fermentation characteristics and methane production. The experimental design was a completely randomized design and the dietary treatments were different levels of RPP supplementation at 0, 4, 8, 12, 16 and 20 mg/0.5 g DM. Under this investigation, RPP supplementation did not affect gas production kinetics and in vitro digestibility (p >.05). The concentration of NH3-N decreased linearly with the increasing levels of RPP supplementation (p <.05). Propionate was increased (p <.05) when supplemented with RPP at 16 mg, while acetate and butyrate remained the same. On the other hand, supplementation of RPP decreased methane production (p <.05). This study indicated that RPP at 16 mg could be used as a rumen enhancer for manipulating rumen fermentation.

The objective of this research was to evaluate the effect of feeding fresh cassava root (CR) along with a feed block containing high was to sulfur (FBS) on feed intake, digestibility, rumen fermentation, and blood thiocyanate concentration in Thai native beef cattle. Four Thai male native beef cattle, initial body weight (BW) of 130 + 20.0 kg, were used in this study. The experiments were randomly assigned according to a 2 × 2 factorial arrangement in a 4 × 4 Latin square design. The main factors were supplemented fresh CR levels (1.0 and 1.5% BW) and across to a feed block supplemented with sulfur added 2% (FBS-2) and 4% (FBS-4). Intakes of rice straw, concentrate diets, and FBS were not affected by treatments. Intakes of CR, sulfur, and total intake were significantly altered by the FBS treatment. The apparent dry matter and organic matter digestibility coefficient were significantly higher in animals fed FBS-4 than in those fed FBS-2. The ruminal ammonia nitrogen concentration was not affected by treatment and ranged from 15.6 to 17.6 mg/dl. Populations of protozoa and fungal zoospores were similar across treatments, whereas the bacterial population was significantly different between sulfur levels in the feed block. Feeding CR with FBS did not change total volatile fatty acid (VFA) concentrations and VFA profiles except for the propionic acid concentration, which was higher in the group with CR supplementation at 1.5% BW. Cattle fed CR with FBS showed similar blood urea nitrogen concentration at various feeding times and overall. In contrast, CR supplementation at 1.5% BW with FBS-2 increased blood thiocyanate concentrations. Therefore, supplementation of FBS-2 was beneficial to Thai native beef cattle fed with 1.5% BW fresh CR as it improved digestibility and rumen fermentation presumed, because HCN from fresh cassava root was converted into thiocyanate, which is nontoxic to farm animals.

Mao pomace meal (MPM) contains condensed tannins and saponins at 92 and 98 g/kg, respectively, and these substances can be used to manipulate ruminal fermentation in ruminant. Four multiparous lactating Holstein cows with 45 ± 5 days in milk were randomly assigned according to a 4 × 4 Latin square design to receive four different levels of MPM supplementation at 0, 100, 200, and 300 g/head/day, respectively. Cows were fed with concentrate diets at 1:1.5 of concentrate to milk yield ratio and urea-treated (3%) rice straw was fed ad libitum. The results revealed that feed intake, nutrient digestibility, blood urea nitrogen, and hematological parameters were not affected by MPM supplementation (p > 0.05). However, ruminal pH and propionate were increased quadratically (p < 0.05) in cows receiving MPM whereas acetate, acetate to propionate ratio and estimate methane production were decreased (p < 0.05). Supplementation of MPM linearly decreased ruminal ammonia nitrogen and protozoal population at 4 hr postfeeding (p < 0.05). Milk production and milk composition were similar among treatments (p > 0.05). In conclusion, supplementation of MPM at 200 g/head/day could modify ruminal fermentation and reduce methane production without adverse effect on feed intake, digestibility, hematological parameters, and milk production in dairy cows.

This experiment was conducted to investigate the effects of replacing rice bran with mao pomace meal on feed intake, digestibility, and rumen fermentation in beef cattle. Four crossbred (50% Brahman × 50% Thai native) beef cattle with an initial body weight of 195 ± 13 kg and 16 months of age were used in a 4 × 4 Latin square design. The dietary treatments included four levels of RB replacement with mao pomace meal at 0, 33, 67, and 100% in concentrate diets. Rice straw was used as a roughage source, fed ad libitum. Replacement of mao pomace meal with rice bran did not affect (p > 0.05) the intakes of concentrate, rice straw, and total dry matter intake. Ether extract intake decreased linearly when increasing the levels of mao pomace meal (p < 0.01). The experimental diets had no effect (p > 0.05) on the digestibility of fiber and crude protein, while dry matter, organic matter, and ether extract digestibility decreased linearly in the group of mao pomace meal replacing rice bran (p < 0.05). Increasing levels of mao pomace meal in concentrate diets did not alter rumen pH, ammonia–nitrogen, or total volatile fatty acid concentration (p > 0.05). The proportion of propionate increased linearly (p < 0.05), whereas acetate and the acetate to propionate ratio decreased linearly (p < 0.05) when replacing rice bran with mao pomace meal. Moreover, the proportion of propionate was greatest, while acetate was lowest when mao pomace meal was included at 100% in the concentrate diet. In conclusion, the replacement of rice bran with mao pomace meal in a diet could enhance the efficiency of rumen fermentation. Nonetheless, it reduced the digestion of nutrients in tropical beef cattle.

In this study, chemical composition, fatty acids, collagen solubility, calpains, and troponin T degradation were investigated in various muscles of native Thai cattle (NTC). Five muscles, namely Bicep femoris, Infraspinatus, Longissimus thoracis, Supraspinatus and Semimembranosus were sampled from five Kho Isaan bulls. Moisture content of Longissimus thoracis was lower (p < 0.05) than others. Protein content of Longissimus thoracis, Bicep femoris and Semimembranosus was higher (p < 0.05) than that of Infraspinatus and Supraspinatus. Infraspinatus and Longissimus thoracis had higher fat content (p < 0.05) than Bicep femoris and Semimembranosus. Muscle pH, color, and drip loss did not differ between muscles. Semimembranosus and Supraspinatus showed higher cook loss (p < 0.05) than Infraspinatus and Longissimus thoracis. Infraspinatus had the lowest Warner–Bratzler shear force (p < 0.05). Supraspinatus, Infraspinatus and Bicep femoris had higher (p < 0.05) soluble, insoluble and total collagen content than Semimembranosus and Longissimus thoracis. Infraspinatus had higher collagen solubility than Semimembranosus and Supraspinatus. Collagen content and solubility were not affected by ageing time. The relative band intensities of intact troponin T and its degradation product at 2- and 14-days postmortem were higher in Longissimus thoracis than in other muscles. Infraspinatus and Supraspinatus had significantly higher expression of m-calpain and calpastatin genes than Longissimus thoracis, Bicep femoris, and Semimembranosus. Total fatty acid was higher while the percentage of C22:6n-3 was lower in Infraspinatus and Longissimus thoracis (p < 0.05) than in other muscles. These results show differences in specific nutritional, technological and eating quality characteristics of NTC muscles and thus provide information for optimizing storage and processing conditions for various NTC muscles.

This experiment was conducted to investigate the utilisation of yeast waste as protein source to replace soybean meal in concentrate mixture on kinetic of gas, rumen ammonia-nitrogen and digestibility of nutrients by using in vitro gas production technique. The experimental design was a completely randomised design and the dietary treatments were replacing soybean meal with yeast wastein concentrate at the ratio of 100: 0, 75: 25, 50: 50, 25: 75 and 0: 100, respectively. Yeast waste was obtained from KSL Green Innovation Public Co. Limited, Thailand. The gas production was recorded at 0, 0.5, 1, 2, 4, 6, 8, 12, 16, 24, 48, 72 and 96 h of incubation. The yeast waste contained 26.4% crude protein. Gas production from soluble fractions (a), gas production from the insoluble fraction (b), potential extent of gas production (a+b) and the gas production rate constants for the insoluble fraction (c) were not altered when increasing concentration of yeast waste replacing soybean meal (P > 0.05). Cumulative gas production (at 96 h of incubation) ranged from 69.3 to 72.8 mL and was similar among treatments. Ruminal NH<inf>3</inf>-N concentration was linearly increased (P < 0.05) whereas ruminal pH did not alter when inclusion various levels of yeast waste replacing soybean meal, which ranged from 15.2 to 19.1 mg/dL and 6.90 to 6.94, respectively. In vitro dry matter digestibility and in vitro organic matter digestibility did not changed by increasing levels of yeast waste in the diets (P > 0.05), except only in vitro dry matter digestibility at 12 h, which higher in soybean meal: yeast waste at 25: 75 ratio (P < 0.05). Furthermore, propionate (C3) molar was linearly higher when compared between inclusion yeast waste and the control group whereas acetate was decreased quadratically (P < 0.05) and protozoal population tended to be decreased (P = 0.07) when increasing the level of replacing yeast waste. In conclusion, yeast waste could replace soybean meal in concentrate mixture with no negative effect on gas kinetics, rumen fermentation and in vitro digestibility, and therefore its use in animal feeding would contribute to a reduction in environmental pollution.

The objective of this study was to determine the influence of urea and whole soybean meal or calcium hydroxide [Ca(OH)<inf>2</inf>] treatment on sugarcane bagasse nutritive values and in vitro fermentation. The experimental design was a completely randomized design (CRD) and the dietary treatments were sugarcane bagasse treated with urea (0, 20, 40g/kg) and whole soybean meal or Ca(OH)<inf>2</inf> (0, 25, 50g/kg). It was found that the protein content of sugarcane bagasse was significantly increased by whole soybean meal and urea treatment, and the values ranged from 65-71 g/kg DM. On the other hand, treatment of Ca(OH)<inf>2</inf> 50 g/kg with urea 40 g/kg could reduce (p<0.05) fiber content of sugarcane bagasse and the values were 533, 514 and 104 g/kg DM for NDF, ADF and ADL, respectively. Gas production from the insoluble fraction (b), potential extent of gas production (a+b) and cumulative gas production were significantly increased (p<0.05) in sugarcane bagasse treated with urea 40 g/kg and urea 40 g/kg + whole soybean meal 25 g/kg (55.3, 53.5 and 50.1 ml), respectively. Urea and Ca(OH)<inf>2</inf> treatment could increase DM and OM degradability, true digestibility and microbial mass of sugarcane bagasse(p<0.05). Furthermore, the concentration of C3, C2 and C2:C3 were improved by urea and whole soybean meal or Ca(OH)<inf>2</inf> treatment. In addition, methane production was decreased in sugarcane bagasse treated with urea 40 g/kg in the present study. Based on this experiment, it could be concluded that treatment of urea and Ca(OH)<inf>2</inf> was an alternative method to improve the nutritive value of sugarcane bagasse, gas production, digestibility and ruminal fermentation characteristics.

The aim of this study was to investigate the effect of Terminalia chebula meal (TCM) supplementation on digestibility, rumen fermentation, nitrogen utilization, and protozoal population in goats. Eight goats with an initial body weight (BW) of 13 ± 3.0 kg were randomly assigned according to a double 4 × 4 Latin square design to receive different levels of TCM supplementation at 0, 8, 16, and 24 g/kg of total dry matter (DM) intake, respectively. The goats were fed with concentrate diets at 13 g/kg BW, while rice straw was used as a roughage source, fed ad libitum. The results revealed that the feed intake and the apparent digestibility of DM, organic matter (OM), neutral detergent fiber (NDF), and acid detergent fiber (ADF) were similar among the treatments (p > 0.05). However, crude protein (CP) digestibility decreased significantly (p < 0.05) when supplemented with TCM at 24 g/kg of total DM intake (p < 0.05). The addition of TCM did not change the ruminal pH and blood urea nitrogen concentrations (p > 0.05), whereas the concentration of NH<inf>3</inf>-N at 4 h post feeding was reduced with the inclusion of TCM at 16 and 24 g/kg of total DM intake. The total numbers of bacteria were enhanced by the addition of TCM, while the protozoal population, in both entodiniomorph and holotrich, was reduced (p < 0.05). The supplementation of TCM did not change the concentration of total volatile fatty acids (TVFA), acetic acid, or butyric acid, while the propionic acid concentration at 4-h post feeding increased significantly, especially when supplemented at 16 g/kg of total DM intake (p < 0.05. In addition, urinary nitrogen (N) excretion decreased, while fecal N excretion, N absorption, N retention, and the proportion of N retention to N intake increased with the inclusion of TCM at all levels. In summary, the inclusion of TCM could improve rumen fermentation efficiency and N balance without having an adverse effect on feed intake, nutrient digestibility, and rumen ecology; however, the protozoal population decreased. Therefore, this study suggests that TCM (16 g/kg of total DM intake) could be used as a plant source for rumen enhancement in goats fed a diet based on rice straw without having an adverse effect on feed intake or nutrient digestion. However, further studies on the production of types of meat and milk that have a long-term feeding trial should be carried out.
