This study examined the effect of supplementing exogenous cellulase on nutrient and energy utilization. Twelve desexed Boer crossbred goats were used in a replicated 3×3 Latin square design with 23-d periods. Dietary treatments were basal diet (control, no cellulase), basal diet plus 2 g unitary cellulase/kg of total mixed ration dry matter (DM), and basal diet plus 2 g compound cellulase/kg of...

This study aimed to determine milk production and efficiency of feed utilization a mixed mineral-enriched essential oils supplementation lactating dairy cows. Forty-eight Holstein-Friesian cows with 3.45±0.58 body condition score 187.08±21.53 days in were randomly allocated two dietary treatments for 46 days. Treatments consisted no (CON) or (AGB) 0.5% Agromix Booster® the Total Mix Ration (TMR...

The objective of this study was to investigate the effects of a flaxseed-supplemented diet on archaeal abundance and gene expression of methanogens in the rumen of dairy cows. In all, 11 non-lactating dairy cows were randomly divided into two groups: group A (five cows) and B (six cows). The two diets fed were: (1) the control diet, a conventional dry cow ration; and (2) the flaxseed-supplement...

Numerical simulation of migration of chemical substances from HDPE into foods(simulants)is performed based on the finite element method(FEM). The results show that concentration of migrants in foods at equilibrium increases with the increase of its initial concentration in packaging. Diffusivity of migrants is key to migration dynamics. Partition coefficient represents ration of concentration i...
