“…The highest Lactobacillus count (P = 0.002) was observed in restricted group 2, which was significantly greater than that in the restricted group, which was in the free range and was significantly lower than that in the AL group. These results correspond with Metzler-Zebeli et al (2019) and Ebeid et al (2022). The proliferation of Lactobacillus is associated with increased lactic acid production, which suppresses pathogen proliferation (Ebeid et al 2022).…”

“…Tumova and Chodova (2018) and Tumova et al (2021; did not observe an effect of feed restriction on the FCR. Ebeid et al (2022) postulated that the decreased growth and feed consumption of restricted chickens might be attributed to a reduction in essential amino acids, which inhibits protein synthesis and increases proteolysis. In addition, pasture access did not have a beneficial effect on the FCR, according to Ponte et al (2008).…”

“…Feed restriction influences the composition of the microbiota in the intestines, for example, increasing Lactobacilleceae in the ileum and caecum (Metzler-Zebeli et al 2019). Moreover, Lactobacillus species produce lactic acid, which suppresses pathogen proliferation and adhesion, leading to stabilisation of the gut microbial ecosystem (Ebeid et al 2022).…”

The aim of the present study was to evaluate the effects of feed restriction and the combination of feed restriction with pasture on the performance parameters of fast-growing chickens, the proportion of internal organs and the caecum microbiota. In the experiment, one-day-old Ross 308 chickens were divided into three groups. Group 1 was fed ad libitum (AL), group 2 was restricted on feed at a rate of 70% ad libitum (R), group 3 was restricted to the same age and level as group 2, and was restricted to 22 days on pasture (FR). Feed restriction and the combination of feed restriction and pasture significantly reduced body weight beginning at the age of 14 days and at the end of the experiment (at 35 days), mortality, and the European Production Efficiency Factor (EPEF) but improved the feed conversion ratio (FCR) beginning at the 4 th week of age. Conversely, feed restriction and the combination of feed restriction and pasture significantly increased the proportion of liver, gizzard and Lactobacillus in the caecum. In summary, feed restriction and the combination of feed restriction in the free range had negative effects on growth, feed conversion ratio and economic profit, presumably because of the short realimentation period and because pasture did not have a beneficial effect.

“…The modern broiler chicken has greater growth rates, better FCR and rapid metabolic rates boosting their sensitivity to nutritional disorders including sudden death syndrome, myopathies and ascites (Ebeid et al, 2022). Quantitative and qualitative feed restriction programs are used to modulate the growth curve and metabolic rates to alleviate the incidence of metabolic disorders and decrease the cost of production (Sahraei, 2014;Aziz et al, 2021).…”

Background: Compensatory growth is a well-established characteristic even in broiler chicken having very short grow-out cycle. Feeding manipulations that take advantages of compensatory growth after a period of nutrient restriction might be beneficial to poultry industry. Methods: In total, 1400 one-day-old straight run broiler chicks (Hubbard) were allocated to 8 experimental treatments, replicated 7 times with 25 chicks in each, in a completely randomized design. The 3 isocaloric corn soybean meal experimental diets; a high BP (HBP) with 1.2% standardized ileal digestible lysine (SID Lys), a medium BP (MBP) with 1.1% SID Lys and a low BP (LBP) 1.0% SID Lys, were offered in starter, grower and finisher phases, as HML (conventional) and LHH, MHH, LMM, MMH, LLM, LLH and LMH as all steps-up. Result: Greater (P less than 0.05) BW and BWG were observed in HML groups during all phases. The MMH group had greater FI (P less than 0.05) during grower and finisher phases. The HML group had better FCR (P less than 0.05) during starter and grower phases. The LMM group had heavier (P less than 0.05) abdominal fat pad, whereas, MHH and HML groups had greater (P less than 0.05) dressed carcass, breast meat, drumstick and thigh yield. The MHH and HML groups, similarly, had higher (P less than 0.05) spleen, thymus, bursa weights, greater antibody titers against NDV and IBDV and total protein concentration. The LLH group had greater (P less than 0.05) blood glucose, urea and total cholesterol concentrations. It is, therefore, recommended that HBP (1.2% SID Lys) should be gradually step down to LBP (1.10% SID Lys) for efficient and sustainable production of broiler chicken.

“…Although it is generally accepted that pellet diets promote broiler growth, several studies have found no difference between the performance of chickens fed pellet or mash diets [7], feed forms are one of the most crucial elements affecting how well broiler chicken utilize their feed. Mash diets gives greater unification of growth, less death loss and are more cost-effective because pellets costs slightly more than the same ration in mash form [8].…”

Aims: The colours of the polymer used during brooding could impair the vision of the chicks. For chicks reared in the dark environment, they have limited access to daylight and find it difficult to gain access to feed and water. Therefore, for better understanding of the effect of the polymer colours on broiler production in the humid tropical climate, a study was carried out to evaluate the effect of coloured polymer light filter and feed forms on performance of broiler chickens. Methodology: A total of two hundred and forty (240) chicks were allocated in 2 × 4 factorial arrangements with two feed forms (mash and pellet). The chicks were reared under four (4) different coloured polymer light filter, namely; white (T1), blue (T2), black (T3), and green (T4) and an incandescent bulb (100 Watts) each. Results: The results showed that the birds reared under the white polymer light filter had the highest weight gain (1565.28 g), while the least weight gain (1469.72 g) was observed in birds reared under black polymer light filter. For rectal temperature of the birds, it was discovered that broiler chicken reared under white polymer light filter had the highest rectal temperature (39.63°C), while the least rectal temperature of 39.33°C was observed in the chicken reared under black polymer light filter. The highest environmental temperature (34.03°C) was observed in birds reared under black polymer light filter, while the least environmental temperature (30.03°C) was observed in birds reared under white polymer light filter. The results further showed that birds fed with pelletized feed form had the highest weight gain than the birds fed with mashed feed form. Conclusions: From the findings of this study, it is certain that polymer light filter and feed forms are important factors that could influence birds’ performance.
