The aim of this study was to test the use of carrot juice fermentation with probiotics in rations with different levels on the production performance and quality of egg-laying hens. The material used was Lohman Brown strain of laying hens, 27 weeks old with an average initial body weight of 1.69 kg, as many as 45 birds. The research was conducted with experimental methods and used a Complete Design Acal (CRD). The treatment tested was the use of Carrot Extract Fermentation (FLSW) with probiotic SOC in the feed consisting of T1 = 100% basal ration, T2 = basal ration (97.5%) + FLSW (2.5%): T3 = basal ration ( 95%) + FLSW (5%); T4 = basal ration (92.5%) + FLSW (7.5%); T5 = basal ration (90%) + FLSW (10%). The variables observed were production performance (consumption, egg production (HDA / Hen Day Average), egg weight, egg mass, feed conversion and income over feed cost) and egg quality variables (albumin index, yolk index, Haugh Unit (HU), yolk color, albumin pH, yolk pH). The results of the analysis of variance showed that the use of carrot extract fermentation (FLSW) with different levels had a significant effect on feed consumption (Sig.115) and HDA (Sig.063), yolk index value (Sig.087) and yolk color (Sig. 000). , and not significantly different on feed conversion (Sig. 403), albumin index value (Sig. 522), and Haugh Unit (Sig. 259). The conclusion of the research showed that the use of fermented carrot juice waste (FLSW) in the feed of laying hens had an effect on feed consumption, egg production (Hen Day Averag / HDA), yolk index and yolk brightness (yolk color), but had no effect on conversion. feed, Haugh unit and albumin index value. Key words : probiotics, fermentation, carrot juice waste, production performance, egg quality

Four groups of 48 laying hens (Gallus domesticus), midway in their laying cycle were fed diets containing graded levels (0.00%, 1.5%, 2.5% and 3.5%) of dietary Nutrafos 3 for 56 days. The completely randomized experimental arrangement was designed to evaluate the responses of the caged layers to the inclusive levels of the additive under humid tropical conditions. The dietary additive produced statistically significant (P< 0.01) improvements in the rate of egg production of the hens. Significant increases (P< 0.01) in feed consumption and improvements in feed efficiency (P < 0.01) were also observed. Haugh unit was significantly (P < 0.05) depressed by dietary Nutrafos 3, especially at the highest level of inclusion. There was no treatment effect on egg size as well as some major anatomical characteristics. The best overall performance was achieved at the 3.5% level of dietary inclusion in contrast to the proprietary recommendation of 2.5%.

An experiment was conducted to determine the effects of feeding diets containing 0, 5, 10, and 15% ground raw rapeseed to three replicates of 14 laying hens each. Isocaloric isonitrogenous diets were fed for a 28-day experimental period and performance and egg quality parameters were measured. Egg production was depressed at the two higher levels of rapeseed inclusion but was not affected at the 5% level of inclusion. Haugh unit, albumen height, and shell deformation were not affected significantly (P > 0.05) but egg weight decreased progressively as rapeseed inclusion increased. Feed consumption was significantly depressed (P < 0.05) at the 15% level of rapeseed and slightly reduced at the other levels.

Two experiments were conducted to compare the performance of Leghorn hens fed a barley-based diet (68.93%) containing three levels of a Trichoderma viride enzyme supplement (0, 100 and 200 mg kg−1 as treatments T2, T3 and T4, respectively) with those obtained when fed a corn-based diet (Treatment T1). In exp. 1, 80 hens were used to determine performance during four 28-d periods, between 21 and 37 wk of age. Egg production, feed consumption, feed efficiency and egg weight of the hens were not affected by enzyme supplement and were similar to those of hens fed the corn diet (P > 0.05). There were also no significant effects on feed consumption per gram of egg or per bird per day (P > 0.05). There was a significant interaction for egg weight between enzyme addition and periods (P < 0.034), indicating that enzyme supplementation improved egg size in the early periods. In exp. 2, 20 hens were fed the same diets to measure water consumption and the ratio of water to feed consumption. Water consumption was not affected (P < 0.07) but the ratio of water to feed was significantly reduced (P < 0.0005) when enzyme was added to the barley-based diet. Water consumption in g d−1 was 172 for T1, 215 for T2, 211 for T3, and 195 for T4, and the water to feed ratios were 1.40, 1.85, 1.66, and 1.56, respectively. These results demonstrate that barley can replace corn in layer diets and that the addition of enzyme to barley-based diets appears to improve egg size and to reduce water consumption relative to feed intake in young laying hens.

Feed shortage had become a major factor constraining the development of animal husbandry. Forage canola has been found to be a potential feed crop due to its high yield and good quality. Therefore, this study mixed different proportions of forage canola to the diet of laying hens and all eggs were collected for analysis. Laying hens were divided into four groups according to the feeding amount of canola: 0 kg, 3 kg, 6 kg, 9 kg, with 30 laying hens in each group. In the feeding trial, there was no negative effect on hen body weight, egg production, or overall egg quality. The results showed that Group B, C and D complete feed consumption is less than Group A. From the spectrum analysis, the trend of the Group A was different from that of the other three groups. After 35 days of rearing, the laying rate of the Group B and the Group C increased about 30% compared to 1 to 7 day. The weight of the Group B and Group C increased about 5% compared with the initial period, while the Group A increased 0.6% and the Group D increased by 3%. The eggshell strength of the Group B and Group C also increased significantly. The contents of phosphorus and potassium in the Group B and C were higher than those in the Group A and Group D. The effects of canola to poultry diets is therefore of practical interest. This study will provide us a potential forage substance in laying hens production performance. © 2021 Friends Science Publishers

In this study, it was investigated the effect of clove oil supplementation at increasing levels into laying hens’ diets on performance, egg quality traits, some blood parameters and yolk TBARS (Thiobarbituric Acid Reagent) values. For this purpose 96 Lohman white laying hens, 28 weeks of age, were divided into four treatment groups. Control group was fed with basal diet (C) and treatment groups were fed with diets formed by addition of clove oil at 50 ppm (CO1), 100 ppm (CO2) and 150 ppm (CO3), respectively. During the trial, feed and water were given as ad-libitum, and poultry house was illuminated for 17 hours. Experiment lasted for 13 weeks. Addition clove oil at increasing rates into diet did not affect the live weight. The data analysed as polynomial showed that supplementation of clove oil into layer diet linearly improved feed conversion ratio and increased the egg production. But, daily feed consumption, egg weight, damaged egg ratio and egg quality parameters were not affected by treatments. Serum parameters such as triglyceride, glucose, aspartate aminotransferase, alanine aminotransferase and calcium were not affected by the clove oil supplementation. TBARS values in C, CO1, and CO2 were found higher than the CO3 group fed with diet including 150 ppm clove oil. In conclusion, clove oil at 150 ppm level in diets of laying hens could be used due to extend the egg shelf life and to decline serum cholesterol content.

Abstract This study was conducted to evaluate the effects of corn protein concentrate (CPC) levels in the diets on laying performance, and egg quality of laying hens. A total of 180 64-wk-old laying hens (2.05 kg ± 0.19 kg of live weight) were randomly assigned to 36 cages (5 birds/cage) with separate feeders, including 6 dietary treatments. Birds were fed 1 of 6 experimental diets containing CPC at different levels (0, 0.5, 1.0, 1.5, 2.0 or 2.5%) for 10 weeks. Diets were isocaloric (2850 Mcal/kg) and isonitrogenous (CP, 15.0%), having similar digestible amino acid profile. Hens were weighed at the beginning and at the end of the experiment to determine BW change. Egg production, feed consumption and egg weight were recorded daily, while egg quality variables were evaluated every 14 days. Data were analyzed using the general linear model procedure of SAS in a complete randomized design. The cage was considered the experimental unit. Linear and quadratic effects of treatment were used for mean separation and significance was declared at P ≤ 0.05. Hens fed CPC maintained BW and gain at an increased rate (Quadraic: P &lt; 0.01). Feed intake increased as CPC increased in the diet (Lineal and quadratic: P &lt; 0.01). Egg production, mass and weight were increased as CPC increased in the diet (Quadraic: P &lt; 0.01). Feed conversion rate was improved as CPC increased in the diet (Lineal and Quadraic: P &lt; 0.02). Shell thickness and breaking strength tended to linearly increased as CPC increased in the diet (P &lt; 0.06). Albumen height and Haugh unit were not altered by dietary treatment (P &gt; 0.25). Yolk color was increased as CPC increased in the diet (P &lt; 0.01). Results from this experiment suggest addition of up to 2.5% CPC in the diet enhances egg production and some parameters of egg quality.

The aim of this study was to explore the potential of Pistacia terebinthus (terebinth) seed meal as a dietary supplement for laying hens. One hundred and ninety-two Babcock 30-week-old laying hens were assigned to one of six treatments (n = 32) with four replicates (n = 8). The hens were fed diets containing 0%, 1%, 2%, 3%, 4%, and 5% terebinth seed meal for eight weeks. Weekly egg production, feed consumption, egg weight, and egg mass were recorded. Egg quality was assessed at the beginning, middle and end of the study. Blood sampling was carried out on 12 birds from each treatment. Total antioxidant capacity, total oxidant status and oxidative stress index were determined. Egg production was greater from hens fed 3% and 4% terebinth than those in the other treatments. Egg weight was increased by supplementation with 2% or more terebinth. Feed consumption, feed conversion ratio, eggshell breaking strength, yolk colour, Haugh units, concentrations of glucose, total cholesterol, high density lipoprotein, low density lipoprotein, alanine aminotransferase, aspartate aminotransferase, total protein, phosphorus and calcium in serum, and total antioxidant capacity, total oxidant status, and the oxidative stress index did not differ across treatments. It is concluded that dietary terebinth seed supplementation generated positive effects on egg production and egg weight without adverse effects on egg quality or the metabolism of the hen.Keywords: antioxidant, egg production, egg quality, feed consumption, serum biochemistry

Poultry Farming

Compound feed are subject to requirements for their composition, since they use several types of grains that contain anti-nutritive substances that reduce the digestibility and use of nutrients. One of the tasks of domestic poultry farming is to reduce losses by increasing the digestibility and accessibility of feed. Among the most effective ways to solve this problem is to add enzymes to the feed of poultry. The inclusion of enzyme drugs in the composition of compound feed contributes to the inactivation of anti-nutritive substances, which contributes to an increase in the coeffi cient of digestibility of nutrients. The purpose of the work was to establish the feasibility and eff ectiveness of the enrichment of compound feed used in the production technology of chicken eggs with mixtures of enzyme drugs of domestic production of Amylosubtilin G3x, Cellolux-F and Protosubtilin G3x. Three groups of laying hens with 57 heads in each have been formed: a control group and two experimental groups. The duration of the experiment was 420 days. Laying hens of the control group have been received farm compound feed depending on their age. Laying hens of the 1st experimental group have been received compound feed of the control group enriched with the enzymes Amylosubtilin G3x and Cellolux-F depending on the age. In the compound feed of laying hens of the 2nd experimental group enzyme drugs were additionally introduced depending on the age Amilosubtilin G3x and Protosubtilin G3x. Higher egg production rates have been observed in the 1st experimental group – 357,81 eggs, which was 6,48 % higher than in the control group and 1,84 % higher than in the 2nd experimental group. The weight of eggs of laying hens of the 1st experimental group was 1,85 g or 2,97 % more, and the 2nd experimental group was 0,7 g or 1,12 % more than in the control group. The diff erence between the egg weight in laying hens of the 1st and 2nd experimental groups was 1,85 % or 1,15 g. The lowest feed consumption of 1,37 kg for the production of 10 eggs was in the laying hens of the 1st experimental group, which was less than the indicator of the control group by 10,94 and by 4,2 % than in the 2nd experimental group.
