Omasal, Reticular Sampling Techniques, and Dual-flow Continuous Culture System for Assessing Ruminal Digestion, Nutrient, and Microbial Protein Flow out of the Rumen and Canola Meal as a Protein Supplement for Lactating Dairy Cows
نویسنده
چکیده
This paper is divided in three components: 1) Comparing the omasal and the reticular sampling techniques; 2) Elaborating on the dual-flow continuous culture system; and 3) Summarizing recent studies on canola meal as the main protein supplement for lactating dairy cows. The goal is to illustrate some peculiarities among these three different methodologies and to point out recent findings on canola meal research.

Estimation of rumen outflow in dairy cows fed grass silage-based diets by use of reticular sampling as an alternative to sampling from the omasal canal.
A study was conducted to compare nutrient flows determined by a reticular sampling technique with those made by sampling digesta from the omasal canal. Six lactating dairy cows fitted with ruminal cannulas were used in a design with a 3 x 2 factorial arrangement of treatments and 4 periods. Treatments were 3 grass silages differing mainly in neutral detergent fiber (NDF) concentrations: 412, 53...
متن کاملEffects of Thyme Essential Oil and Disodium Fumarate on Ruminal Fermentation Characteristics, Microbial Population and Nutrient Flow in a Dual Flow Continuous Culture System
The aim of the present study was to investigate the effects of di-sodium fumarate (DSF) and thyme essential oil (TEO) solely and simultaneously on ruminal fermentation properties and microbial abundance. A dual-flow continuous culture system (DFCC) with eight 1400-mL fermenters was used in a period of 12 d that divided to 9 d for adaptation and 3 d for sampling. Fermenters were fed 100 g d...
متن کاملEffect of source of rumen-degraded protein on production and ruminal metabolism in lactating dairy cows.
Twenty-eight (8 with ruminal cannulas) lactating Holstein cows were assigned to seven 4 x 4 Latin squares in a 16-wk trial to study the effects on production and ruminal metabolism of feeding differing proportions of rumen-degraded protein (RDP) from soybean meal and urea. Diets contained [dry matter (DM) basis] 40% corn silage, 15% alfalfa silage, 28 to 30% high-moisture corn, plus varying lev...
متن کاملInvestigation of Ruminal Degradability and Intestinal Digestibility in Soybean and Canola Meals Coated with Different Fat Sources
The aim of this study was to evaluate the in vitro effect of coating soybean meal and canola meal with different fat sources on ruminal degradability and intestinal digestibility, as well as, the in vivo digestibility. For this purpose, calcium salt of omega-3, calcium salts of unsaturated fatty acids and prilled fat were used for coating. To determine ruminal degradability, three lactating Hol...
متن کاملEffect of Processing Protein Supplements with Tannin Extracted from Pistachio by-Products on Performance of Holstein Dairy Cows in Early Lactation
This experiment was conducted to evaluate the effects of processing protein meals by tannin extracted from pistachio by-product on apparent total tract digestibility, ruminal fermentation and performance of dairy cows. For tannin extraction, one kilogram of sun-dried pistachio by-products was immersed in four liters of water for 48 h. Then, pistachio by-products were removed from the water and ...
