This paper examines the nutritional and veterinary effects of tannins on ruminants and makes some comparisons with non-ruminants. Tannin chemistry per se is not covered and readers are referred to several excellent reviews instead: (a) Okuda T et al. Heterocycles 30:1195–1218 (1990); (b) Ferreira D and Slade D. Nat Prod Rep 19:517–541 (2002); (c) Yoshida T et al. In Studies in Natural Product C...

Several points of view may be taken if we want to describe a dairy farm. An animal nutritionist would focus on the individual animal and describe how feeds are transformed to meat, bones, tissues, skin, hair, embryos, milk, manure etc. A physiologist would further describe the roles of the various organs in this process and how the transformations are regulated by hormones. A biochemist would e...

Since the 1940s, the widespread adoption of synthetic fertilizers has reduced the need for manure as a nutrient source in crop production. This has led to separation of crop and animal production, increased use of imported feeds, and a growth in animal numbers relative to land area on dairy and other livestock farms. A net flow of nutrients into areas with a concentration of dairies is now comm...

This article aims to assess the feasibility of using native legumes as alternative sources protein in compound feeds by poultry producers and pig producers. Data achieve this objective came from a direct survey conducted 2018, with twenty-three Measures descriptive statistics were used calculations. The collected information was analyzed then described statistical methods. research data databas...

Zeolites are crystalline hydrated tektoalumosilicates consisting of a three-dimensional framework of SiO4 4and AlO4 5tetrahedra linked through shared oxygen atoms. The heulandite group of zeolites including clinoptilolite are the most abundant zeolites in nature 1, 2 . Clinoptilolite is used in a wide range of industrial and agricultural applications, particularly in animal nutrition. Dietary i...

Since the use of antibiotics in animal feeds has been banned, researches on alternative natural products that modulate ruminal fermentation have been intensified. Natural compounds such as plant extracts have been considered to be replaced antibiotics as safe and sustainable alternatives. Plant extracts especially essential oils and saponins have strong antimicrobial, antiparasitic, antiprotozo...
