Abstract The aim of this study was to determine the effect of coating urea by chitosan at graded levels on ammonia concentration and rumen fermentation in vitro. This study used Factorial Randomized Complete Block Design (RCBD) to test ammonia parameter and Randomized Complete Block Design (RCBD) for pH, microbial protein synthesis, dry matter and organic matter digestibility, and Volatile Fatty Acid (VFA). The treatments tested were: P0 = addition non coating urea 1%; P1 = coating urea by chitosan 1%; P2 = coating urea by chitosan 2%; P3 = coating urea by chitosan 3%. The data obtained were analysed by using ANOVA and continued with Tukey HSD test with SPSS version 25. The results of this study showed that the coating of urea chitosan had no significant effect on pH, dry matter and organic matter digestibility, microbial protein synthesis, and amonia concentration in the rumen. However, it significantly reduced (P <0.05) total VFA concentration. It can be concluded that the application of urea coating by chitosan does not affect on the degradation of urea in the rumen.

Four concentrations (0, 200, 400, 600 and 800 mg extract per ml of water) of mesquite extract were used as phytogenic additive to verify the potential to increase the nutritional value of the feed, ruminal parameters (primarily propionate production) and nitrogen use efficiency, microbial protein synthesis and quantify the reduction of ciliated protozoa and characterize the ingestive behavior of sheep. Ten adult male sheep were subjected to a 5 × 5 double Latin square design. Prior to feeding, the animals received the mesquite extract. Nutrient intake was estimated from the difference of the amount of feed provided and the total surplus. Rumen content samples were collected to evaluate the profile of short-chain fatty acids, ammonia nitrogen, pH, ciliated protozoa, turnover rate and disappearance rate. To estimate the microbial protein synthesis, the technique of purine derivatives was used. The mesquite extract quadratically increased (P < 0.05) the digestibility of dry matter, organic matter, crude protein and total digestible nutrients, as well as increased propionate production, acetate:propionate ratio and microbial protein synthesis. The numbers of ciliate protozoa in the rumen decreased as a result of mesquite extract inclusion in the diet. The use of mesquite pod extract at a concentration of 488 mg/mL is recommended to improve digestibility of dry matter, organic matter, crude protein and total digestible nutrients, and to optimize microbial protein synthesis and increase propionic acid production.

Replacement of chemical compounds by dietary sources as rumen enhancers have been of great interest and concern by researchers. Four, rumen-fistulated swamp buffalo bulls with average liveweight of 365 ± 15.0 kg were randomly assigned to treatments, to investigate the impact of banana flower powder (BAFLOP) as a rumen modifier on pH, rumen fermentation, nutrient digestibility, microbial protein synthesis and volatile fatty acids. All buffaloes were allotted according to a 4 × 4 Latin square design. Dietary supplementation treatments were as follows: 2 g concentrate/kg bodyweight (BW; T1), 15 g concentrate/kg BW (T2), 15 g concentrate/kg BW plus BAFLOP 300 g/head.day (T3) and 15 g concentrate/kg BW plus BAFLOP 600 g/head.day (T4). Untreated rice straw was fed ad libitum. The findings showed that total feed intake was increased in buffaloes fed a diet supplemented with concentrate at 2 g/kg BW, while rice straw intake was reduced. Nutrient digestibility was increased by BAFLOP supplementation at both levels (T3 and T4; P &lt; 0.05). Ruminal pH dropped (5.9) in buffaloes fed with concentrate at 15 g/kg BW, while buffaloes with BAFLOP supplementation could maintain ruminal pH when fed with high-concentrate diet. Ruminal ammonia-nitrogen increased in the buffaloes fed concentrate at 15 g/kg BW, especially with BAFLOP supplementation. Feeding high-concentrate diet increased the concentrations of ruminal total volatile fatty acids and propionic acid (C3), while the concentration of acetic acid and the acetic acid:C3 ratio and methane production were subsequently reduced (P &lt; 0.05). In addition, efficiency of microbial protein synthesis was increased by the BAFLOP feeding (P &lt; 0.05). In the present study, using BAFLOP as a dietary rumen enhancer at 300–600 g/head.day resulted in an increased rumen pH, C3 concentration, nutrient digestibility and microbial protein synthesis, while mitigating ruminal methane production. Higher nutrient digestibility and lower ruminal methane production, more dietary energy and production efficiency are expected.

The study compared the influence of chitosan sources on rumen fermentation, methane emission and milk production in lactating dairy cows fed a glycerin-based diet. Six, lactating Holstein-Frisian crossbreeds (410 &plusmn; 5.0 kg BW, 120 &plusmn; 21 day-in-milk), were arranged in a 3 x 3 replicated Latin square design. In addition to control, a 2% chitosan extract supplement and a 2% commercial chitosan supplement of dry matter intake were the treatments. The results denoted that no significant differences on daily dry matter, nutrients or estimated energy intake were noted when cows received different sources of chitosan. Nutrient digestibility was not influenced differently by extraction based or commercial chitosan supplements. The pH, temperature, ammonia nitrogen, blood urea and microbial count were similar among treatments. The different sources of chitosan supplements did not change the totals of volatile fatty acids, acetate and butyrate; in contrast, different chitosan sources influenced (P&lt;0.05) propionate content. The ruminal acetate to propionate ratio was markedly (P&lt;0.05) reduced with chitosan supplement, but no change appeared between sources of chitosan. At 4 hours after feeding, the methane estimation significantly decreased with the addition of chitosan supplementation (P&lt;0.05) compared to the control group. The purine derivatives and microbial protein synthesis were not altered by the treatments. No significant differences existed on milk yield, milk composition or milk urea nitrogen when cows received different sources of chitosan (P&gt;0.05). In sum, supplementing extracted chitosan showed more potential than did commercial chitosan for enhancing economic efficiency and recycling shrimp residues, therefore, reducing environmental waste.
