Effect of urea and molasses fermented cassava pulp on rumen fermentation, microbial population and microbial protein synthesis in beef cattle

Effects of cassava chips (Manihot esculenta Crantz) and rain tree pods (Samanea saman) fermented with traditional fermentation starter (loog-pang kaomark) on growth performance, rumen fermentation, and microbial population in goats

To obtain guidelines for improving the quality of animal feed on production performance, rumen fermentation, and microbial population in goats. A total of 16 native-bore crossbred goats were used. A randomized complete block design (RCBD) was planned to compare four supplementation forms. There were four different loog-pang kaomark fermented cassava chips and rain tree pods (CRFLK) at proportions 100:0, 60:40, 50:50, and 40:60, respectively. The results of this study found that rice straw intake in terms of kg was higher in goats fed CRFLK 50:50, 60:40, and 40:60. While CP, NDF, and ADF digestibility were increased in goat fed CRFLK 50:50 and 40:60. The concentration of acetic acid was decreased by supplementation of CRFLK (p < 0.05) whereas NH3-N and propionic acid were increased (p < 0.05) by goat fed CRFLK. However, CH4 was decreased (p < 0.05) as a result of supplementation of CRFLK. The goat fed CRFLK decreased the protozoal population (p < 0.05). Moreover, the bacteria population was increased by fed with CRFLK (p < 0.05). This study concluded that feeding concentrate inclusion with CRFLK 50:50 and 40:60 resulted in higher propionic acid, CP digestibility, and lowest CH4 production.

Comparative study of depotash vinasse and molasses as binder and production performance in lactating Murrah buffaloes

Dairy sector has recently focused a lot of attention on the addition of agricultural by-products as functional feed additives as an environmentally friendly and sustainable technology. Depotash vinasse (DPV) serves as a cheap source of nutrients and a binder for animal feed in dairy sector. However, there is little information available on the usage of depotash vinasse on animals. Therefore, the aim of the present study was to assess the role of depotash vinasse as pellet binder on nutrient digestibility, blood parameters and milk production in early lactating Murrah buffaloes. Fifteen Murrah buffaloes (daily milk yield 8.5 to 9.0 kg/day) were randomly assigned to three groups, viz., control, group 1 (G1) and group 2 (G2) on the basis of milk yield and days in milk. The control group animals received a basal diet of concentrate mix, oat greens and wheat straw, G1 animals received molasses as a binder (8%), while G2 received DPV as binder (8%). Results revealed that there was no significant effect on nutrient digestibility. Blood parameters and hepatic enzymes were statistically similar (P > 0.05). Supplementation of depotash vinasse as binder had no effect on plasma minerals and was comparable to control group. There were no changes in milk production and 6% fat-corrected milk yield in treated groups as compared to control. It was concluded that depotash vinasse (8%) may be used for pellet production with no negative impact on milk yield and composition, nutrient digestibility and blood biochemical parameters in early lactating buffaloes.
