to determine the chemical compositions, minerals and in vitro digestibility lathyrus sativusstraw during three years in shahrekord, kohrang and lordegan climates in chaharmahal & bakhtiari. this was one of the important legume straws that farmers used in ruminant winter diets in south west of iran. this legume straw gathered of different climates for three years. all samples were chemically ana...

Zinc concentrations in alfalfa hay were varied using a N-Zn liquid fertilizer as a foliar applicant (.34 or .68 kg Zn/ha) or as a soil fertilizer (4.07 kg Zn/ha). Mean concentrations of Zn across five cuttings of alfalfa in 2 yr were 18, 27, 41 and 21 mg Zn/kg DM for control, low foliar, high foliar and soil treatments, respectively. Each treatment was fed in ad libitum amounts to eight crossbr...

Three experiments were conducted to measure energy and nutrient digestibility in dried distillers grain with solubles (DDGS) by growing pigs. In Exp. 1, apparent (AID) and standardized (SID) ileal digestibility coefficients of CP and amino acids (AA) were determined in four samples of DDGS using growing pigs equipped with a T-cannula in the distal ileum. Exp. 2 was an energy balance experiment ...

The effect of type of fiber, site of fermentation, method for quantifying insoluble and soluble dietary fiber, and their correction for intestinal mucin on fiber digestibility were examined in rabbits. Three diets differing in soluble fiber were formulated (8.5% soluble fiber, on DM basis, in the low soluble fiber [LSF] diet; 10.2% in the medium soluble fiber [MSF] diet; and 14.5% in the high s...

The ability of young and mature horses to digest DM, OM, and NDF was compared using 6 weanling colts and 6 mature (13.2 ± 3.0 yr) geldings. Each colt was paired with a gelding, and the pair was adapted to a diet containing 67% alfalfa cubes and 33% concentrate for 21 d. During the adaptation period, horses were accustomed to housing and all handling procedures. The adaptation period was also us...
