Estimating dry matter digestibility and intake in wapiti (Cervus elaphus canadensis) using the double n-alkane ratio technique
We estimated dry matter digestibility and intake (DMI) in wapiti hinds using the double n-alkane method. We also assessed intra-ruminal controlled-release devices (CRD) for administering n-alkane markers C32 and C36. Nine wapiti hinds were offered alfalfa-based compounded diet for ad libitum consumption and actual DMI was measured daily (mean: 9.2 1.6 kg DM/day). The DMI estimate for C33:C32 (9...

Effect of Millettia ferruginea (Birbra) foliage supplementation on feed intake, digestibility, body weight change and carcass characterstics of Washera sheep fed natural pasture grass hay basal diet
Twenty-four yearling male local Washera lambs with an average initial body weight of 18.14 ± 1.07 kg were used to assess the nutritional value of Millettia ferruginea. Experimental animals were grouped into six blocks of four animals, and each animal was randomly assigned to one of the four dietary treatment feeds. The treatments used were; Sole natural pasture grass hay (T1), and 150, 300, 450...
متن کاملInfluence of feed intake level on site of digestion in steers fed a high concentrate diet.
A high concentrate diet was fed at 1.2, 1.5, 1.8 and 2.1% of body weight to four Angus steers (258 kg) equipped with cannulas in the proximal duodenum and distal ileum. As level of feed intake increased, flow of N, nonammonia N, microbial N and feed N to the small intestine increased linearly (P less than .05). Bypass of feed N increased from 44 to 71% of fed N. At the highest intake level, rum...
متن کاملThe Use of N-alkanes as Markers for Determination of Intake and Digestibility of Fish Feed
Introduction Measurements of intake and digestibility are among the most critical estimates needed to determine the nutrient requirements and feed utilization in fish. Many methods have been devised to study these parameters, but all have their shortcomings and disadvantages, as direct measurements are not applicable. One of the most common methods used to measure intake of livestock is based o...
