“…Blood metabolites and liver hormone Nir et al (1996) reviewed the metabolic and hormonal changes in chickens as a consequence of feed restriction. In the present study, at the end of the feed restriction period, the TC levels in the feed restricted groups were higher than in the ad libitum group, in agreement with Ebeid et al (2012).…”

A total of 144 weaned hybrid HYLA rabbits (40-day-old) were randomly divided into 4 groups, to investigate the effects of the intensity of one week's feed restriction on short-and medium-term growth performance, blood metabolites and hepatic IGF-1 in growing rabbits. Restricted groups were fed with 30% (Group L30), 50% (Group L50) 70% (Group L70) of ad libitum feeding for 1 wk and then fed ad libitum until the end of the experiment (75 d of age). The control group (Group AL) was fed ad libitum throughout the experiment. Total feed intake (-15.8%) and feed conversion ratio (-13.2%) were lower in the L50 than in the AL group (P<0.05), but no difference was found between the L30, L70 and AL groups (P>0.05) for these parameters. Total weight gain did not significantly differ among the 4 experimental groups (38.5 g/d; P>0.05). At the end of the feed restriction period, the total serum protein level (P=0.01) was higher in restricted rabbits than AL rabbits (P<0.01), while the hepatic IGF-1 level was lower in L30 and L50 groups than in the 2 other groups (P<0.001). However, no difference remained between groups at the end of the experiment. In contrast, calcium, triglycerides, alkaline phosphatase, urea nitrogen and total cholesterol levels were similar between groups (P>0.05) throughout the experiment. In conclusion, a short-term feed restriction improves feed conversion ratio in a lasting way, transiently alters serum protein and IFG-1 levels and leads to compensatory growth in growing rabbits.

“…Unfortunately, this growth rate is accompanied by increased body fat deposition, high mortality and high incidence of metabolic diseases and skeletal disorders (Zubair and Leeson, 1996). These situations most commonly occur with broilers that consume feed ad libitum when compared to feed restricted birds (Nir et al, 1996). Thus feed restriction has been proposed to reduce these problems.…”

“…Our concerns with using lighting programs to limit access to feed, and thereby reduce feed intake are: (1) limiting early (before 10 d of age) feed access may negatively impact the development of the gastro intestinal tract (Dibner et al 1996) such that overall growth and ability to convert dietary nutrients to body weight are restricted; (2) use of lighting programs to restrict growth may result in increased bird injury during peak feeding when lights come on after an extended dark period [injury from scratching may increase incidence of cellulitis (Elfadil et al 1996), or muscle or skeletal injury reducing growth and value (Julian 2000)]; (3) reduced early growth may be too severe for broilers marketed at younger ages (<35 d) to fully recover, thus increasing days to market; and (4) gorging on feed (e.g., prior to extended dark periods) may increase gut growth (Joly 1994;Nir et al 1996) and thereby bird maintenance costs (Dibner et al 1996), and also increase feed passage rate through the gut and result in reduced feed utilization (May and Lott 1992).…”

Scott, T. A. 2002. Evaluation of lighting programs, diet density, and short-term use of mash as compared to crumbled starter to reduce incidence of sudden death syndrome in broiler chicks to 35 d of age. Can. J. Anim. Sci. 82: 375-383. Restricted lighting is used commercially to regulate early growth and limit losses associated with sudden death syndrome (SDS), ascites and leg problems. Standard lighting programs may not be suited for broilers marketed at 35 d of age, and promote injury (scratching, i.e., cellulitis) by creating peak feeding periods. This study evaluates four lighting programs, three phases of mash or crumble starter feeding and two diet densities on performance and mortality of broilers marketed at 35 d of age. Two trials each Low as compared to high-density diets did reduce SDS mortality significantly (0.72 vs. 1.81%, respectively). Lighting programs that do provide variable extended dark periods will alleviate broiler mortality as compared to constant (23 or 16 h ) or intermittent lighting programs. However, these broilers had a significantly lower body weight when marketed at 35 or less days of age.
