Compensatory responses to short-term feed restriction during the growing period in swine.
Two experiments involving 288 pigs were conducted to determine the effects of shortterm feed restriction during the growing period on average daily gain (ADG), average daily feed consumption, feed required/unit of gain (F/G), age at 100 kg and average backfat depth at 100 kg. Pigs were fed 100, 85 or 70% of ad libitum consumption for 2or 4-wk periods in Exp. 1 and 100 or 85% for 2or 4-wk period...
متن کاملMolt performance and bone density of cortical, medullary, and cancellous bone in laying hens during feed restriction or alfalfa-based feed molt.
A study was conducted to evaluate the effects of alfalfa-based molt diets on molting performance and bone qualities. A total of 36 Single Comb White Leghorn hens were used for the study. There were 6 treatments: pretrial control (PC), fully fed (FF), feed withdrawal (FW), 90% alfalfa:10% layer ration (A90), 80% alfalfa:20% layer ration (A80), and 70% alfalfa:30% layer ration (A70). For the PC t...
متن کاملEffect of Dietary Supplementation of Liquid Prebiotic and Antibiotic on Egg Production, Egg Quality, Blood Parameters, Immune System Response of Layer Hens at Post Molt Period
Extended Abstract Introduction and Objective: The inclusion of prebiotics in layer hen diets can act as a growth-promoting antibiotic replacer and have beneficial effects on egg production and egg quality. This study aimed to investigate the effects of liquid prebiotic on the post-molt laying performance, egg quality at different storage temperatures and times, immune system function, and bloo...
متن کاملthe effects of using alfalfa-based molt diet compared with feed deprivation on blood parameters changes during molt period and post-molt performance of commercial laying hens
introduction: induced molting is a process that stimulates natural molting events. when birds return to full feed, a new plumage develops and the birds resume egg peroduction at a higher rate with better egg quality. induced molting extends the productive liffe of commercial chicken flocks and results in substantial reduction in the number of chickens needed to produce the nation's egg supply. ...
متن کاملFeed Restriction in Broiler Chickens Production
The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...
