Adapting feeding system is an effective way for improving the nutritional quality of milk as currently intended by dairy industry. The objectives of this work were (1) to characterize milk from feeding systems based on herbage or corn silage with or without flaxseed and (2) to authenticate the milk from the three systems on the basis of the fatty acid (FA) profile. Bulk milk samples were collec...

The preservation of forages by ensiling has been a well known technology for many years and is popular in North America and Europe. This technology requires high investment in facilities, accurate timing in the several stages of the ensiling process, and better understanding of the whole process than hay making demands. In addition to these demands, silage making and management in tropical cond...

Khorvash, M., Colombatto, D., Beauchemin, K. A., Ghorbani, G. R. and Samei, A. 2006. Use of absorbants and inoculants to enhance the quality of corn silage. Can. J. Anim. Sci. 86: 97–107. This study examined whether inoculants and various absorbent materials could be used during ensiling to reduce effluent losses and improve nutritive value of corn silage. Two corn forages were harvested: conve...

Two trials were implemented to explore nutritional strategies to improve lactation performance of dairy cows fed red clover silage (RCS)-based diets. In Trial 1, 18 earlyto midlactation dairy cows were assigned to a replicated 3 × 3 Latin square trial design and fed diets containing forage bases of all RCS, a mixture of RCS and brown midrib corn silage (BMR), and a mixture of RCS and normal cor...

Three 2.4-ha wheat (Triticum aestivum L.) fields were used to test the effects of maturity at harvest (boot vs. dough) and preservation method (hay vs. silage) on forage yield, chemical composition, and animal performance when fed in mixed diets. Forages were incorporated into 4 diets in a 2 x 2 factorial arrangement of treatments with hominy feed, soybean hulls, and cottonseed meal as the prim...

Twenty-four multiparous Holstein-Friesian dairy cows were used in a replicated 3×3 Latin square changeover design experiment to test the effects of changing from corn (Zea mays) silage to red clover (Trifolium pratense) silage in graded proportions on feed intakes, milk production, and whole-body N and P partitioning. Three dietary treatments with ad libitum access to 1 of 3 forage mixtures plu...

The objective of this study was to determine the effects of a homolactic acid inoculant on ensiling characteristics and nutritive value of high dry matter (DM) alfalfa. The ensiling characteristics were determined by ensiling inoculated and untreated alfalfa haylage in mini-silos for 0, 2, 4, 8, 16 and 45 days. Two lactating cows fitted with ruminal fistulas were used to determine ruminal degra...

This study examined ruminal microbial community composition alterations during initial adaption to and following incubation in a rumen simulation system (Rusitec) using grass or corn silage as substrates. Samples were collected from fermenter liquids at 0, 2, 4, 12, 24, and 48 h and from feed residues at 0, 24, and 48 h after initiation of incubation (period 1) and on day 13 (period 2). Microbi...

E-mail address: [email protected] Silage has been the prevailing type of preserved forage for cattle feeding in many countries. Carry-over of some components from silage to cow’s milk has been thus of concern. Silage is a richer source of available provitamins A, o...

Kura clover (Trifolium ambiguumM. Bieb.) grown in monoculture is difficult to harvest mechanically because of its decumbent growth habit, and legumes in general have poor ensiling characteristics. Our objectives were to assess forage yield, nutritive value, and silage characteristics of kura clover–winter wheat (Triticum aestivum L.) mixtures to determine usefulness as a silage crop. ‘Cardinal’...
