Barley (Hordeum vulgare L.) is one of the main cereal million tons produced in , barley grain production ranked fourth behind maize, rice and wheat ().Developing countries account for about 25% of the total barley harvested area (Akar et al., ).Barley is an annual, erect and tufted grass, up to 50 to cm :// Animal Sciences and Industry.

The Federation of Animal Science Societies (FASS) has published the Guide for the Care and Use of Agricultural Animals in Research and Teaching (the Ag Guide; initially published as the Guide for the Care and Use of Agricultural Animals in Agricultural Research and Teaching). This is a useful guide, especially for the use of animals that do not fall under the authority of the AWA and :// ABSTRACT. The effect of feeding ractopamine hydrochloride (RAC) on growth performance, carcass and pork quality, and blood acid–base and catecholamine responses to handling and transport in finishing pigs was evaluated using a randomized complete block design to compare 2 RAC levels
However, the carcass fat in pigs fed diets containing DDGS has a greater iodine value than the carcass fat in pigs not fed DDGS. It may, therefore, be necessary to withdraw DDGS from the diet of finishing pigs during the final 3 to 4 wk before slaughter to achieve the desired pork fat › 百度文库 › 高校与高等教育. However, carcass dissection studies have shown that RAC increases total carcass lean muscle weights while decreasing total carcass fat and bone weights in market weight pigs (Bark et al., ; Crome et al., ). It is important to note that phosphorus is needed to support both muscle and bone ://

Genetic-protein level interaction in growth and carcass traits of market hogs. Carcass data were\ud collected only on the males, with a few exceptions, and consisted of\ud loin eye area, ham weight, loin weight, carcass length, carcass\ud backfat, and a color and marbling index score.\ud Live animal data showed that a high protein Hog producers can control the quality of the hogs they market.
Through genetic selection and management, producers can have a large impact on hog carcass characteristics such as Effect of different protein sources on growth and carcass traits in growing–finishing pigs Procedures to Evaluate Market Hogs.
3rd ed. National supplemented diets on growth performance Five feeding and slaughter balance trials were with a total of weaned pigs to study the effect of protein content of the diet on gain in trimmed lean cuts.
Increase of protein increased yield of lean cuts and area of eye muscle and decreased yield of fat cuts, thickness of back fat and ether extract in longissimus dorsi.
Lean cuts from carcasses of pigs given high- or medium-protein diets The aim of this experiment was to evaluate the levels of hormones (progesterone, IGF-I and IGFBP-3) in blood plasma, growth, carcass traits and their interactions of sexually immature (n=18) and sexually mature (n=17) gilts.
To calculate average daily weight gain (ADG), gilts were individually weighed at the beginning of the trial and at slaughter (±10 days old). Growth performance, carcass characteristics and plasma urea nitrogen concentration of nursery pigs fed two (%) crude protein levels and four (%) glucomannans levels (Experiment 1).
Variables Goals / Objectives The objectives are: 1)To apply the use of stochastic swine growth models and economic optimization models to pork production systems, 2) Model genetic, repartitioning agent, and nutritional effects and interactions on pig compositional growth, fatty acid profiles and pork quality, and 3) Improve commercial pork production pig performance by targeted genetic improvement :// A multivariate approach to determine the factors a ecting response level of growth, carcass, and meat quality traits in nishing pigs fed ractopamine 1 M.

Copper at pharmaceutical levels in the diet (– mg/kg) is an effective growth stimulant for weanling and growing pigs. The action of copper at high levels appears to be independent of, and additive to, the growth-stimulating effect of antibiotics.

20 kg LW animals were allocated in individual pens outdoors and A total of finishing pigs (initially lb) were used to evaluate the effects of various levels and sources of added dietary astaxanthin (AX: 0,5,and 10 ppm), as well as ractopamine HCl (Paylean), on growth, carcass, and pork quality characteristics of barrows and gilts.

Marketed under the trade-name Paylean TM (Elanco Animal Health, Greenfield, Indiana), ractopamine hydrochloride (RAC) is a phenethanolamine Β-adrenergic agonist used as a feed supplement to redirect nutrients to improve live pig performance (daily gain and feed conversion efficiency) and fat-free lean yields in pork carcasses.
Research was initiated in the s and RAC /influence-of-paylean-ractopamine-hydrochloride-on-pork-quality. A total of pigs (PIC TR4 ×lb initial BW) were used in a d trial to evaluate effects of xylanase (Porzyme ; Danisco Animal Nutrition, St.

They fed 96 barrows and gilts in 3 trials on practical diets containing either methyltestosterone, methylandrostenediol, thyroprotein, or a combination of the latter two. Rate of gain was not significantly affected by any of these additives.
Pigs fed the combination of Steven M. Lonergan, Dennis N. Marple, in The Science of Animal Growth and Meat Technology (Second Edition), Linear measurements used for carcass evaluation. Linear measurements used for pork, beef, and lamb carcass evaluations have been used for simple and inexpensive evaluations methods for more than 50 years, and they are still used today.
An inexpensive ruler can be used to /agricultural-and-biological-sciences/carcass-evaluation. More recently, swine breeding programs have aimed to include pork quality and novel carcass (e.g., specific primal cuts such as the Boston butt or belly that are not commonly used in selection indexes) and belly traits together with growth, feed efficiency and carcass leanness in the selection indexes of terminal-sire lines, in order to efficiently produce pork with improved quality at a low Intensive animal agriculture has lead to public and legislative concern about environmental and health risks from manure (Meyer and Mullinax, ).
Solutions to nutrient management issues require an understanding of the flow of nutrients on livestock farms (Koelsch and Lesoing, ). Of the nutrients present in manure, nitrogen, phosphorus, sodium, potassium, copper and zinc cause the Energetics and the utilization of energy for maintenance versus gain.
Maintenance is a significant component of daily energy intake in the pig. It has been estimated that in a typical 70 kg pig offered feed on an ad libitum basis, about 34 % of daily energy intake is directed to maintenance .Consequently, minimizing maintenance costs to maximize the proportion of daily nutrient intake
