For the request of rational and scientific farming of dairy cow, the database of dairy cow’s feed composition and ratio is established, and the feed formula service management platform and transaction processing platform is realized in Science Feed Management System. The application of this system contributes to improve science of dairy cow’s feed formula, enhance the utilization of the raw mat...

Thirty six male Chall lambs (four-month old and 26  ±1.5 kg body weight) were randomly assigned into four treatments (nine lambs per treatment) to study the effect of Powerfeed® (a commercial mixture made from wheat processing by-product and wheat bran) on weight gain, feed intake, feed conversion ratio, serum sodium and potassium concentration and urine pH. Lambs in control group were fed with...

the objectives for this study were first to understand and estimate energy consumption in each stage of production and processing of milk using regional data and second, suggesting improvement opportunities. a cradle to gate assessment of market milk was performed by separating the system into three stages: agronomy, animal farm and processing plant. data were collected from multiple sources e....

The present study was conducted to evaluate the effects of physical form of starter and alfalfa hay (AH) provision on growth performance, ruminal fermentation, and blood metabolites of Holstein dairy calves. Forty-four 3d-old Holstein dairy calves with a mean starting BW of 39.9 ± 1.1 kg were used in a 2 × 2 factorial arrangement. The factors were dietary forage level (0 or 150 g kg-1</sup...

A study was conducted to determine the effects of a replacement finisher feed (RF) on carcass yield and carcass bacteria recovery. RF is a commercial formulation of a D-glucose polymer (maltodextrin) with added salts and vitamins. Commercial male broilers (41 d of age) were given either RF or control-feed (traditional starter feed) for 8 h, followed by feed withdrawal for 0, 4, 8, or 12 h befor...

acid-binding capacity (abc) of a feed is the amount of acid required to reduce the ph of feed to a special level such as 3. all poultry feed ingredients used in this study were collected from feed mills in iran. the ph and abc were determined using the standard methods in deionized and magnetized water at room and body temperatures. the ph of most feed ingredients was raised in magnetized water...
