The effects of dietary extruded linseed (EL) on growth performance, meat quality, and lipid profile of Semimembranosus and Longissimus lumborum muscles of 81 Sarda lambs were studied in a 3 × 3 design: EL content (0%, 10%, and 20%) of maternal dietary concentrate fed from 20 d to parturition to 60 d of lactation and EL content (0%, 10%, 20%) of lamb concentrate fed after weaning for 30 d. The b...
this study was conducted to determine nutritive value of common animal feed sources in east azerbaijan province including second cutting of alfalfa hay ( n=35) and wheat straw (n=26). chemical composition and mineral contents of alfalfa hay and wheat straw were determined according to standard methods. then the average chemical compositions of these samples were compared with those of the gilan...
Alfalfa is usually wilted 15% or less moisture prior to baling for hay. However, harvesting at low moistures increases loss of leaves (protein) during baling and reduces nutritive value. In addition, long wilting times increases the risk for damage from rain. In order to retain more nutrients and prevent rain damage, hay can be baled at higher moistures but the risk of spoilage from undesirable...
The key chemical analysis used to estimate the energy value of alfalfa hay for trading purposes, ADF (acid detergent fiber), has been supplanted by NDF (neutral detergent fiber) as the key chemical analysis used by nutritionists to evaluate the fibrosity and energy value of alfalfa hay for nutritional purposes. It is important that the alfalfa hay trading industry abandon ADF, as it will genera...
OBJECTIVE To measure pH, volatile fatty acid (VFA) concentrations, and lactate concentrations in stomach contents and determine number and severity of gastric lesions in horses fed bromegrass hay and alfalfa hay-grain diets. ANIMALS Six 7-year-old horses. PROCEDURE A gastric cannula was inserted in each horse. Horses were fed each diet, using a randomized crossover design. Stomach contents ...
Perennial forage production exists in Ontario to support the livestock industry, but also provides nesting habitat for grassland birds such as threatened Bobolink (Dolichonyx oryzivorus) and Eastern Meadowlark (Sturnella magna). Delaying hay harvest until July 15 or later allows most nestling leave nest, nutritional value of decreases substantially. This project estimated economic impact delayi...
Supplementation of forage-fed livestock has been studied for decades; however, as by-products become available research is needed to determine optimal feeding rates for increased efficiency. Five ruminally and duodenally cannulated beef steers (446 +/- 42 kg of initial BW) were used in a 5 x 5 Latin square to evaluate effects of increasing level of supplemental corn distillers dried grains with...
The objective of this study was to evaluate the effect of partially replacing forage sources (alfalfa hay) with treated wheat straw on nutrient digestibility, chewing activity, blood metabolites, rumen fermentation, and performance of finishing lambs. Wheat straw (WS) was treated with 7 % sodium hydroxide, 3.5 % salt, and 3.3 % calcium carbonate and then ensiled for 2 months. Twenty-three male ...
OBJECTIVES The balance between interferon gamma (IFN gamma) and interleukin 4 (IL4) producing T cells (T1 and T2 cells) seems to be of importance in many (auto)immune disorders. In general, T1 cell activity is important in cellular immunity whereas T2 cell activity plays a part in humoral responses. T1 cell activity predominates in joints of patients with rheumatoid arthritis (RA) whereas T2 ce...
Three experiments were conducted to evaluate the response of supplementing primiparous heifers based on the metabolizable protein (MP) system during pregnancy and lactation. In Exp. 1, 12 pregnant, March-calving heifers (432 +/- 10 kg) grazing Sandhills range were randomly allotted to one of two treatments: supplementation based on either the MP system (MPR) or the CP system (CPR). Supplements ...
