this experiment was conducted to consider the effects of maturity and cutting time on chemical composition and available protein content of alfalfa hay for dairy cows.. alfalfa hay harvested at two maturity stages (pre-bloom and early bloom) and two cutting times (morning and afternoon). available protein was predicted using nrc (2001) and dve/oeb (1994) models. in the nrc model (2001), alfalfa...

Molting is a process commonly utilized by commercial laying facilities to extend and improve the productivity of a flock. This practice usually involves the deprivation of feed for a period of several days in order to rejuvenate the reproductive system. Due to food safety and comsumer awareness factors, alternatives to this approach are being investigated. Feeding alfalfa as an insoluble fiber ...

this experiment was conducted for three consecutive years from 2000 to 2002 to evaluate the effects of integrated weed management on weeds of alfalfa at the safi abad agricultural research farm of dezful. the experimental design was a randomized complete block with strip-split plot arrangement of treatments. herbicide treatment was as horizontal factor at five levels which in 2000, consisted of...

Honeycomb mass selection design have been used in a genetic broad based ecotype of Alfalfa to assess its efficiency in yield improvement through two cycles of selection. The selection intensities used were: 14.26%, 7.69% and 5.26% in the first and 14.26%, 7.69%, 5.26%, 2%, 3.22%, 2.77% in the second cycle of selection. According to the results obtained from field trials it was concluded that th...

introduction using agro-industrial by-products in ruminants feeding could help in semi arid climate condition throughout the year. raisin by-product is produced in huge magnitude in malayer city, hamedan province. local different raisin by-products which produced during machinery cleaning and sorting of sun dried treated grapevine cluster (vitisvinifera l. cv. sultana), are as:1) some outer lay...

Twenty-four lactating Holstein dairy cows (12 first lactation and 12 multiparous; day in milk = 11 ± 5 days) were allotted to a randomised complete block design in a 2 × 3 factorial with four replicates per treatment to evaluate the effects of two methods of alfalfa feeding (dry and reconstituted to achieve a theoretical dry matter (DM) content of 350 g/kg) and three geometric mean (GM) particl...

OBJECTIVE This study was conducted to determine molecular structures related to carbohydrates and lipid in alfalfa hay cut at early bud, late bud and early flower and in the afternoon and next morning using Fourier transform infrared spectroscopy (FT/IR) and to determine their relationship with alfalfa hay nutrient profile and availability in ruminants. METHODS Chemical composition analysis, ...

High fiber and nonstarch polysaccharide-based poultry diets have received more interest recently for retaining or promoting beneficial gastrointestinal microbial populations. The objective of this study was to investigate and compare the in vitro potential fermentability of high-fiber feed substrates (HFFS) by laying hen cecal microflora. Feed sources examined included soybean meal, soybean hul...

Potential biological control inoculants, Pseudomonas fluorescens 2-79 and microbial communities derived from market sprouts or laboratory-grown alfalfa sprouts, were introduced into alfalfa seeds with and without a Salmonella inoculum. We examined their ability to inhibit the growth of this foodborne pathogen and assess the relative effects of the inoculants on the alfalfa microbial community s...
