the objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (dm), crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) of ten pasture forage species dominant in the west provinces of iran. duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. the chemical com...

An in vitro experiment was conducted to study the effect of non-fiber carbohydrates (NFC) on ruminaldisappearance kinetics of dry matter (DM) and neutral detergent fiber (NDF) of alfalfa hay, wheat bran andunmolassed sugar beet pulp. Non-supplemented or NFC supplemented samples [70 mg/g DM of each feedsample as sucrose (SU) or starch (ST) or SU + ST as 1:1] were incubated in bottles containing ...

The chemical composition, in situ  rumen degradability coefficients of dry matter (DM) and crude protein (CP), in vitro gas production and in vivo  digestibility were evaluated for olive cake (OC) silage treated (DM basis) with different additives as follows: (1) untreated OC; (2) OC, 8% molasses and 0.4% formic acid and (3) OC, 8% molasses, 0.4% formic acid and 0.5% urea. After addition of the...

A trial involving a 2x2 factorial arrangement of treatments was conducted to evaluate two corn silage hybrids (Agromen, AGN35-A42) and (Bayer, A3663) and concentrate levels (25 and 50%) on animal performance. Twenty-four Holstein x Zebu crossbred steers, averaging 335±30kg of BW, were distributed in six randomized blocks to evaluate intake, digestibility, and performance. Treatments consisted o...

The aims of this study were to determine the effects of feeding medium-roasted soybean meal (SBM) and corn dried distiller's grains with solubles (CDDGS) in dairy cows on milk production and income over feed costs. A randomized complete block design experiment was conducted with 24 crossbred multiparous Holstein Friesian dairy cows in early- and mid-lactation. Four dietary treatments were as fo...

21 Three levels of metabolizable protein supply (108, 98–95 and 85 g PDIE kg DM) (PDIE: protein digested in the small intestine when rumen-fermentable energy is limiting) in the diet and three levels of difference between rumen-degradable 21 energy and N (PDIE 2 PDIN 5 0, 10 and 20 g kg DM) (PDIN: protein digested in the small intestine when rumenfermentable nitrogen is limiting) were used in t...

This experiment evaluated different strategies for allocating first-cut grass silages to dry dairy cows that had low body-condition score (BCS) at drying off. A total of 48 moderately yielding Holstein-Friesian cows were used, receiving one of three dietary treatments in the dry period and a single lactation diet based on a flat-rate of concentrates and grass silage ad libitum. Throughout the d...

to evaluate the effects of garlic on some blood metabolites in pre-partum dairy goats, the ration was supplemented with raw garlic at the doses of 0, 30, 50 and 70 g kg-1 of dry matter (dm) in eight pregnant mahabadi breed goats (59 ± 1 kg initial live weight) in a replicated latin square design during the last two months of pregnancy. each experimental period lasted 14 days with the first 12 d...

In this work we studied the relationship between kiwifruit dry matter (DW) measured using the destructive method with a fruit dehydrator (Nesco/American Harvest®, Wisconsin, USA) and a non-destructive Kiwi meter sensor (Turoni Inc., Forli, Italy). This was an approach to develop a reliable non-destructive method to predict harvest and postharvest quality based on dry matter. There was a signifi...

This study presents the chemical composition and in vitro fermentation of five diets with different forage (alfalfa) to concentrate (faba bean) (F:C) ratios, F0:C100, F25:C75, F50:C50, F75:C25, F100:C0 on a dry matter (DM) basis. Results indicate that the chemical composition in term of organic matter (OM), ether extract (EE), crude protein (CP), acid detergent fiber (ADF), neutral detergent fi...
