“…They correlated breaking strength with egg production and ash percentage; the lower the egg production, the higher the breaking strength. In our case, overall egg production was higher in the HB hens ( Sharma et al., 2020 ) than in W-36 hens, whereas ash percentage was similar in both strains. Sparke et al.…”

“…Cortical and trabecular BMD was higher in W-36 hens than in HB hens; however, total and trabecular BMC was higher in HB hens than in W-36 hens. These differences might be due to the difference in egg production ( Sharma et al., 2020 ), wherein overall hen day egg production eggshell percentage, and eggshell thickness were higher in the HB hens than in W-36 hens. Although total and cortical BV was higher in the HB hens, higher BV/TV was observed in the W-36 group, which further supports the fact that higher mobilization of bone for egg production might occur.…”

“…Eggshell thickness was measured using an Ames micrometer (B. C. Ames Incorporated, MA) at the top, equator, and bottom of the eggshell, and the average measurement was obtained. Eggshell breaking strength was measured using an Instron Universal Testing Machine model 3,345 (Instron Inc., Norwood, MA), at a constant crosshead speed of 20 mm/min using a 100-N static load cell and a 35-mm circular steel probe as a compression device ( Clerici et al., 2006 ; Sharma et al., 2020 ). To calculate the eggshell percentage, eggs were broken, and the eggshell was rinsed with tap water to clear the albumin and then allowed to dry for 2 d. Eggshell percentage was calculated by dividing the eggshell weight by egg weight and multiplying by 100 ( Sharma et al., 2020 ).…”

Effects of the housing environment and laying hen strain on tibia and femur bone properties of different laying phases of Hy-Line hens

et al. 2021

This study aimed to determine the effect of the housing environment and laying hen strain on tibia and femur properties. A 3 × 2 factorial arrangement of 3 housing environments (conventional cages [ CC ], enriched colony cages [ EC ], and free range [ FR ]) and 2 laying hen strains (Hy-Line W-36 [ W-36 ] and Hy-Line Brown [ HB ]) in a completely randomized design was conducted from 32 to 85 wk of age. Six left tibias were collected at 8 different time points (38, 45, 52, 59, 65, 72, 79, and 85 wk of age), whereas 6 left femurs were collected at 3 time points (38, 65, and 85 wk of age). Tibias were evaluated for tibia breaking strength ( TBS ) and ash percentage, whereas femurs were evaluated for bone mineral density ( BMD ), bone mineral content, bone volume as a fraction tissue volume, and porosity percentage from total, cortical, medullary, and trabecular bones. The higher TBS ( P = 0.0005) and ash percentage ( P = 0.045) was observed in hens raised in FR systems compared with those raised in the CC. Overall, TBS of W-36 hens was significantly greater than that of HB hens ( P < 0.0001); however, there was no difference in the ash percentage between the strains ( P > 0.05). An interaction between the housing environment and hen strain was observed for BMD ( P = 0.04), wherein W-36 hens raised in the FR system had higher BMD than HB hens. Similarly, hens raised in FR systems had higher trabecular bone volume than those raised in CC ( P = 0.022). Hen strain influenced total and cortical bone properties: BMD, bone volume as a fraction tissue volume, and porosity percentage, wherein W-36 hens had better properties than HB hens ( P < 0.05). Trabecular BMD was higher in W-36 hens than in HB hens ( P = 0.04), whereas bone volume was higher in HB hens ( P < 0.0001). The results suggest that raising laying hens in alternative housing systems that have provision for exercise such as FR reduces structural bone loss, stimulate structural bone formation, and improve breaking strength of bones; however, it varies with the strain.

“…These features have been attributed to bioactive compounds (i.e., hydrocarbons, phenols, esters, alcohols, acids, and steroids) present in phytogenic products, which have positive effects on animal production and health ( Shirani et al., 2019 ). Other characteristics of phytogenic feed additives include an increase in the production of digestive secretions such as endogenous digestive enzymes, saliva, bile, and mucin ( Brenes and Roura, 2010 ; Sharma et al., 2020 ). Therefore, phytogenic feed additives can influence animal productive and physiological responses, both quantitatively and qualitatively.…”

Productive parameters, cecal microflora, nutrient digestibility, antioxidant status, and thigh muscle fatty acid profile in broiler chickens fed with Eucalyptus globulus essential oil

This study was conducted to evaluate the effects of different dietary inclusion of eucalyptus essential oil ( EEO ) on growth performance, relative organ weight, cecal microflora, nutrient digestibility, serum biochemical parameters, and thigh muscle fatty acid profile in broiler chickens. A total of six hundred 1-day-old male broiler chickens were randomly allocated into 5 treatment groups with 8 replicate pens, and each pen contained 15 birds. The experiment lasted for 42 d. Dietary treatments included corn–soybean meal-based diet supplemented with 0, 250, 500, 750, and 1,000 mg/kg EEO. The results indicated that dietary treatments had no effect on growth performance parameters in the 1 to 10 d period. From day 11 to 24, dietary supplementation of EEO showed a linear decrease in feed conversion ratio ( FCR , P < 0.05). From day 25 to 42 and the overall period (1–42 d), broilers fed with different levels of EEO showed a linear increase in body weight gain ( BWG ) and reduction in feed conversion ratio (linear, P < 0.05). The relative organ weight were unaffected by any of the dietary treatments. With increasing levels of EEO, the cecal Escherichia coli (linear, P = 0.085) count showed a trend in reduction, and the cecal lactic acid bacteria population tended to increase (linear, P = 0.063). The apparent ileal digestibility of ether extract and organic matter were linearly and quadratically increased in response to increasing dietary EEO supplementation ( P < 0.05). A trend of linear decrease in total cholesterol in the serum of birds fed with different levels of EEO was recorded ( P = 0.074). Eucalyptus essential oil's inclusion increased serum superoxide dismutase linearly but reduced serum malondialdehyde linearly ( P < 0.05). Dietary supplementation of EEO affected the fatty acid profile of thigh muscle so that increased the concentrations of total polyunsaturated fatty acids (linear, P < 0.05) and reduced total saturated fatty acid contents (linear, P < 0.05). Taken together, the inclusion of EEO increased BWG and decreased FCR during day 25 to 42 and day 1 to 42, and partially improved cecal microflora balance, nutrient digestibility, antioxidant activity, and thigh muscle fatty acid profile in broiler chickens.

“…Its vitamin content is excellent; primarily a source of vitamin D. Egg is rich in carotene and contains most of the minerals for example calcium, iron, and phosphorus. The quality of egg is significantly influenced by animal feed quality [10]. The protein, fat, and carbohydrate contents of eggs are summarized in Table 1.…”

Nutrition plays a very important role in healthful living. Daily consumption of balanced diet is pertinent to mainatin good health. Eggs contain both macronutrients as well as micronutrients, which are essential to the body. Eggs are one of the richest sources of complex protein (5 g/piece). The complex protein need for the normal healthy diet is 75-80 g. Therefore, eggs help to provide the amount of aminoacids required for the human body. Amino acids perform many functions. It is primarily a building block of proteins, thus helping the human body to develop. Proteins increase the muscle mass and prevent their breakdown. This also serves as an energy reserve that is why a high protein egg is called a complex protein. In addition, to its positive biological values, it has significant cholesterol content as well. Due to this reason, it is imperative to reduce consumption of eggs in case of high-cholesterol. Eggs are also suitable for enriching the foods in order to increase the nutritional value of the product. The consumption of raw egg must be avoided as it can be the source of infections in humans. Contamination of eggs poses a high risk to food safety. Good hygienic practice is highly imperative to mainatin high quality and safety of eggs. In the manuscript, we summarize the most important properties of the eggs in healthy diet. Furthermore, we are also looking for a place in international gastronomy. It is hoped that the nutritionists and other scientists can get a new knowledge through our publication.
