Digestibility, microbial protein synthesis, rumen and blood parameters in sheep fed diets containing hydroponic barley fodder
This experiment was conducted to determine the possibility of replacing part of the barley grain by hydroponic barley fodder (HBF), and evaluating its effect on digestibility, rumen parameters, microbial protein synthesis and blood parameters in sheep. Four male Kermani sheep, 18-month-old (34.7 ± 1 kg live weight) were randomly assigned to a change over 4 × 4 design and fed the experimental di...
متن کاملEffect of wheat forage maturity and preservation method on forage chemical composition and performance of growing calves fed mixed diets.
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...
متن کاملMicrobial Activity in Bovine Rumen
bengal, asparagus agar (Allen, 1951), asparagus agar plus 1:80,000 crystal violet, and asparagus agar plus 1:15,000 rose bengal. The addition of dyes decreased the number of contaminants but also appeared to inhibit the development of the rhizobia. All plates were examined daily for 2 weeks. Smears of colonies which resembled rhizobia were examined. Pure cultures were obtained by the use of bot...
متن کاملRumen microbial ecosystem
The inhabitants of the rumen microbial eco-system, a complex consortium of different microbial groups living in symbiotic relationship with the host, act synergistically for the bioconversion of lignocellulosic feeds into volatile fatty acids which serve as a source of energy for the animals. The constraints, imposed by the host and the feed consumed by the animal, under which these microbes ha...
متن کاملEstimation of Rumen Microbial Protein Supply Using Urinary Purine Derivatives Excretion in Crossbred Calves Fed at Different Levels of Feed Intake
A study was carried out to study the response of total purine derivatives (PD) excretion in urine to determine microbial N (MN) supply at four fixed levels of feed intake (namely 95, 80, 60 and 40% of voluntary intake). The crossbred (CB) calves were allocated according to a 4×4 Latin Square Design and fed wheat straw and concentrate (1:1). The rate of PD excretion (mmol/d) as a linear function...
