“…Higher energy content of the current feed caused lower feed intake that agree with Valkonen et al [17,18]. [16] report but disagree with the Riberio PAP et al [19] who reported higher feed intake from using higher energy feed compared to using lower energy feed.…”

Four experimental rations were formulated from locally available protein and energy source feed to study its effect on the production performance, on some egg quality traits for fayoumi chickens and to know the financially feasibility of such locally formulated rations for fayoumi layer chickens. Ninety six fayoumi chickens of 24 weeks of age were subjected to four formulated rations. Each of the four treatments were replicated three times with 8 birds (1 male: 7 females) per replicate. Each replicate feed was fed in group in feeding pens. Feed intake and egg production data were collected daily for each replicate. Dry matter feed intake was not significantly different (P >0.05) between treatments 1 and 3, and between treatments 2 and 4. Significantly higher (P<0.05) egg production and egg weight were observed in treatment 2 with no significant difference (P>0.05) among the other three treatments. Egg shell weight (g), shell thickness (mm) and Yolk color did not differ (P>0.05) significantly among the treatments. In the current study net profit of 47.2, 39.4, 21.41 and 15.3 Ethiopian Birr were obtained per bird on treatments 2, 3, 4 and 1 respectively within six months of feeding period. Locally available protein and energy source feed can be used for the formulation of nutritionally balanced and economically feasible diet for fayoumi layers chickens. Ration formulated from 0.5% limestone, 0.5% salt, 1% layers premixes, 28% wheat bran, 3.5% fish meal, 11.5% soybean, 32% maize and 23% noug cake was found to be financially feasible and recommendable in areas with similar climatic conditions to Adami Tulu area and in area where these feed ingredients are available.

“…And this decrease in intake, physiologically, can be caused by the presence of lipid in the duodenum that stimulates the release of hormone cholecystokinin (CCK), that causes the enterogastric reflex, decreasing passage rate through the digestive system, with consequent absorption of nutrients (Brunelli et al, 2010;Pinheiro et al, 2012;Torres and Drehe, 2015). However, the modern laying hens have the ability to adjust feed intake from food energy content (Gunawardana et al, 2008;Ribeiro et al, 2014).…”

This study aimed to evaluate the inclusion of pirarucu by-product acid silage meal in diets for laying hens on performance and egg quality. One hundred sixty eight Hissex White laying hens 73-wk-old were distributed in completely randomized design with seven treatments (0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0%) and four replicates of six birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of pirarucu by-product meal levels were determined by polynomial regression. Differences (p<0.05) were observed in all variables of performance, in egg weight, yolk height and yolk pigmentation, with pirarucu by-product meal inclusion in diets showed better results than control diet. The pirarucu by-product acid silage meal can be used as alternative food in diets for commercial laying hens. Up to the 2.5% inclusion level there wasn't negative effect in performance and egg quality.

“…(2008) demonstrated that feed intake increased with increasing dietary energy levels from 2,390 to 2,629 kcal/kg feed. These conflicting results may be attributed to differences in environmental conditions, diet composition, egg production, hens' genotype, and age ( Ribeiro et al., 2014 , Classen, 2017 ). In a recently published review, Classen (2017) demonstrated that the nature of the feed intake response to dietary energy is neither uniform nor predictable in laying hens.…”

Effects of dietary probiotic (Pediococcus acidilactici) supplementation on productive performance, egg quality, and body composition in laying hens fed diets varying in energy density

et al. 2020

This study was conducted to determine the effect of probiotic Pediococcus acidilactici ( PA ) strain MA18/5M supplementation of diets with different dietary energy levels on productive performance, egg quality, and body composition in Hy-Line Brown hens during a 16-week period from 32 to 47 wk of age. The experimental treatments with a 2 × 2 factorial design received a 2 wheat–corn–soybean diet: a moderately low energy density diet with 2,650 kcal ME/kg ( M-LED ) and a low energy density diet based on the M-LED diet with 2,550 kcal ME/kg ( LED ), each diet without and with probiotic supplementation (M-LED, LED, M-LEDp , and LEDp , respectively). Reduced dietary energy levels had a particularly negative effect on egg weight (61.7 vs. 63.3 g; −2.6%, P < 0.001), egg mass output (1.67 vs. 1.71 kg; −2.4%, P = 0.015), and FCR (2.01 vs. 1.97 kg feed/kg egg; +2%, P = 0.028). In hens administered the LED diet, deteriorated productive performance was accompanied by greater body weight loss ( P < 0.001) and reduced abdominal fat content ( P < 0.033) as compared with the M-LED group. Dietary probiotic inclusion increased egg weight ( P = 0.015), including relative eggshell weight ( P = 0.008) and eggshell thickness ( P = 0.002) and significantly improved FCR ( P = 0.010). No interactions between the PA-based probiotic and dietary energy levels were found in any of the tested parameters. Adding the probiotic on top of the M-LED diet improved layers performance but resulted in nonbioequivalence for the egg weight, egg mass output, and FCR compared with this group without probiotic. Probiotic supplementation of the LEDp diet improved all performance parameters except for egg weight. As a result, the laying rate, egg mass output, daily feed intake, and FCR in the LEDp treatment were bioequivalent to those noted in the M-LED group without the probiotic. The results of a bioequivalence test suggest that a low energy diet fed to laying hens promoted a probiotic response to improve energy utilization by birds.
