“…Inherent low nutritive values of RS limit its utilization by rumen microorganisms and consequently by the host animal. Treating RS with urea can be a routine practice, safe to use, provides a source of inorganic nitrogen (N) that is deficient in RS ( Van Soest, 2006 ) and increases the fiber degradation in the rumen ( Yulistiani et al, 2011 ). Although the digestibility of urea-treated rice straw (TRS) has been shown to be improved when fed as a sole diet to sheep, the animals showed negative N balance and lost body weight (BW) due to low voluntary feed intake ( Elseed, 2004 ).…”

A digestibility study was conducted to evaluate the effects of supplementing mulberry foliage and urea rice-bran as a source of fermentable energy and protein to 12 sheep fed diets based on urea-treated rice straw (TRS). The three dietary treatments were: T1, TRS with mulberry; T2, TRS with 50% mulberry replaced with rice bran and urea; and T3, TRS with rice bran and urea. The study was arranged in a completely randomized design with four replications for each treatment. The sheep were fed one of the three diets and the supplements were offered at 1.2% of the body weight (BW) and the TRS was provided ad libitum. There were no differences (p>0.05) among the three treatment groups with respect to dry matter (DM) intake (76.8±4.2 g/kg BW0.75) and DM, organic matter (OM), and crude protein (CP) digestibility (55.3±1.22; 69.9±0.85; 46.3±1.65% respectively for DM, OM, and CP). The digestibility of fiber (neutral detergent fiber [NDF] and acid detergent fiber) was significantly lower (p<0.05) for T3 (46.2 and 46.6 respectively) compared to T1 (55.8 and 53.7 respectively) and T2 (54.1 and 52.8 respectively). Nitrogen (N) intake by sheep on diet T3 was significantly (p<0.05) higher than sheep fed diet T1. However, N balance did not differ among the three diets (3.0±0.32 g/d). In contrast, the rumen ammonia (NH3-N) concentrations in sheep fed T2 and T3 were significantly (p<0.05) higher than in sheep fed T1. The NH3-N concentrations for all three diets were above the critical value required for optimum rumen microbial growth and synthesis. Total volatile fatty acid concentrations were highest (p<0.05) in T1 (120.3 mM), whilst the molar proportion of propionic acid was highest in T3 (36.9%). However, the microbial N supply in sheep fed T1 and T3 was similar but was significantly (p<0.05) higher than for sheep fed T2. It was concluded that mulberry foliage is a potential supplement of fermentable energy and protein for sheep fed TRS based diet. The suggested level of supplementation is 1.2% of BW or 32% of the total diet since it resulted in similar effects on the intake of DM, OM, and NDF, digestibility of DM, OM, and CP, N utilization and microbial supply when compared to rice bran and urea supplementation.

The addition probiotics brings several benefit including protect the environment by reducing ammonia gas. This research aims to evaluate probiotics as a substitute for AGP on carcass percentage and physical quality of broiler’s meat. This experiment used 300 Lohmann broilers day old chick (DOC) is divided into 3 groups of treatment and 5 replications in each treatment during the 35 days. The experimental design used was Completely Randomized Design (CRD) with three treatments, there are P0: (basal diet); P1: (P0 + AGP zinc bacitracin 0.04%); P2: (P0 + probiotics in drinking water). The parameters measured were carcass percentage, pH, tenderness, meat cooking loss, water holding capacity and organoleptic. All data collected within the present study were analyzed using Analysis of Variance and if there were significant differences further tests needed to be performed with Duncan’s multiple range test by SPSS version 25. The results showed that the probiotics not significantly (P>0.05) influenced carcass percentage, pH, cooking loss, and organoleptic values include aroma and flavor of broiler’s meat. The probiotics significantly (P<0.05) influenced tenderness, water holding capacity and organoleptic value including texture of broiler’s meat. From these results, it can be concluded that probiotics increased the tenderness of meat and water binding capacity. Probiotics also influence the consumer’s taste for the texture of broiler meat. The AGP can be replaced by probiotics for broilers.

“…Treating rice straw with urea is a common practice that is safe to use and usually utilized to supply inorganic nitrogen (N) that is lacking in RS [1]. According to [2] the addition of urea to RS improves the fiber degradation in the rumen. However, feeding urea-treated rice straw as a sole diet to sheep is reported to improve digestibility, but the associated low VFI results in negative N balance and loss of body weight [3].…”

Three experiments were conducted to measure the preference, voluntary feed intake (VFI), and digestibility of forest type (FT) sheep fed untreated rice straw (RS) and supplemented with either sole or combined fodder tree leaves [Leucaena (L), Samanea (S) or Gliricidia (G) and their equal combinations]. The preference index (PI) was determined by consumption difference of the three fodder tree leaves (FTL), using 12 FT sheep (6 rams and 6 ewes of average weight 17.0 ± 1 kg). The sheep were offered the FTL in a cafeteria-style, and the consumption within the first 1 h was used to rank them. The sheep showed marked preference (P < 0.0001) for Leucaena over either Samanea or Gliricidia. The PI followed this order: Leucaena > Samanea > Gliricidia. For the VFI study, a total of 24 FT sheep (16 rams and 8 ewes) of average weight 17.0 ± 1.0 kg were randomly assigned to 1 of 8 dietary treatments in a completely randomized design. The treatments were T1 (100% urea-ammoniated straw), T2 (RS + 100% L), T3 (RS + 100% S), T4 (RS + 100% G), T5 (RS + 50% L: 50% S), T6 (RS + 50% L: 50% G), T7 (RS + 50% G: 50% S), T8 (RS + 33% L: 33% G: 33% S). There were significant differences in the total and straw DM intakes. Total DM intake ranged from (523 to 694 g/d) whilst straw DM intake ranged from (430 to 692 g/d). The highest (P < 0.0001) total and straw DM intake were observed in sheep fed T8 and T1 diets compared to the other treatment diets. Feeding sole Gliricidia resulted in the lowest straw and total DM intakes but combining it with either Leucaena or Samanea improved intakes. In the digestibility study, 16 rams (average weight = 17.0 ± 1.0 kg) and same treatments for the VFI study were used to determine DM digestibility (DMD) and digestible organic matter in dry matter (DOMD). The DMD values ranged from 52.50% to 67.20 % while the DOMD was between 55.14 and 70.36%. Feeding T1 resulted in the highest (P = 0.027) DMD, and (P < 0.0001) DOMD but combining the FTL improved DMD and DOMD for the supplemented diets. The results of the study indicated that feeding combined FTL (3 FTL) resulted in a similar performance as that of the urea-ammoniated straw and could be used a low-cost protein supplement for sheep on low-quality roughage.
