“…Similar results were observed by Vieira et al (2011), when evaluating the calcium levels of 28, 33 and 38 g/kg in the diet of brown egg layers from 40 weeks of age, and by Pelícia (2009b), in an experiment with brown egg layers in the period from 59 to 70 weeks of age fed diets containing the calcium levels of 30, 35, 40 and 45 g/kg. These authors verified increase in the calcium excretion, in g/bird/day and in g/kg, respectively, and attributed this result to the concentration of calcium in the diet.…”

“…In this sense, Vieira et al (2011), evaluating the calcium levels of 28, 33 and 38 g/kg for brown egg layers at 40 weeks of age, verified that the calcium levels also did not influence the calcium deposition in the shell (g/kg), as in the results obtained by Lichovnicova (2007) with commercial layers at the post-peak of laying. Thus, the efficiency of calcium deposition in the shell reduced with the increase of calcium in the diet.…”

“…Therefore, it can be affirmed that there was decreasing effect in the efficiency of calcium retention as the level of calcium in the diet increased, which was also observed by Vieira et al (2011).…”

“…Vieira et al (2011) recommended calcium at the level of 34.1 g/kg and Dantas et al (2010), at 41.3 g/kg of diet, whereas Rostagno et al (2011) recommended the levels of 40.2 g/kg for calcium and 3.0 g/kg for phosphorus. However, Lelis et al (2009) indicated the level of 2.3 g/kg for phosphorus.…”

-The experiment was conducted to determine the nutritional requirement of calcium and the best calcium: available phosphorus ratio for commercial layers at the post-laying peak. A total of 324 Hy-Line W-36 laying hens were utilized in the period from 42 to 58 weeks of age, distributed in a completely randomized design in a 3 × 3 factorial arrangement, composed of three levels of calcium (39, 42 and 45 g/kg) and three calcium:phosphorus ratios (12.12:1; 10.53:1; and 9.30:1), totaling nine treatments with six replications and six birds per experimental unit. There was no significant effect from the calcium levels × calcium:phosphorus ratio interaction for any of the variables studied. The calcium levels and the calcium: phosphorus ratios did not affect the variables performance or egg and bone quality. At the evaluation of the calcium:phosphorus balance, as the levels of calcium of the diet were raised, the intake of calcium and phosphorus and the contents of mineral matter and calcium in the excreta increased linearly, and the retention of calcium by birds decreased linearly. With the reduction of the calcium:phosphorus ratios of the diet, intake, retention and excretion of phosphorus by layers increased. Diets containing calcium at 39 g/kg and a calcium:phosphorus ratio of 12.12:1, corresponding to an increase in calcium of 3.51 g/bird/day and available phosphorus of 289 mg/bird/day, meet the requirements of calcium and available phosphorus of white egg layers in the period from 42 to 58 weeks of age.

“…In agreement with this study, Underwood and Suttle (1999) stated that calcium was absorbed based on the requirements. Improvement in calcium intake and retention did not affect eggshell weight since calcium deposition was maintained to be constant (Lichovnicova, 2007;Vieira et al, 2011). The unused calcium for egg formation was deposited in bone (Bar, 2008), or excreted through excreta (Wahju, 2004).…”

The objective of this study was to investigate the effect of hatchery waste meal (HWM) as a whole or without shell (shell-less) in the diet on nutrient retention and performance of quails. The study used 500 female quails (Coturnix coturnix japonica) aged 30 days with an average initial body weight of 94.75±4.17 gr. The quails were randomly allocated to five dietary treatments in a completely randomized design with 5 replicates of 20 quails. The dietary treatments were: Control = basal diet, Whole 4% = 96% basal diet + 4% whole HWM, Whole 8% = 92% basal diet + 8% whole HWM, Shell-less HWM 4% = 96% basal diet + 4% of shell-less HWM, Shell-less HWM 8% = 92% basal diet + 8% of shell-less HWM. The data were subjected to analysis of variance, when the treatments indicated significant effect it was continued with Duncan’s Multiple Range Test. Quails fed HWM up to 8% improved (P<0.05) their crude fat retention, apparent metabolizable energy, calcium consumption and calcium retention (P<0.05). In addition, HWM in the ration increased the performance, and also yolk and albumen weight, but decreased (P<0.05) yolk and albumen index. It can be concluded that HWM improved performance and nutrient retention of quails.

Implications of butyrate and its derivatives for gut health and animal production

2018

Butyrate is produced by microbial fermentation in the large intestine of humans and animals. It serves as not only a primary nutrient that provides energy to colonocytes, but also a cellular mediator regulating multiple functions of gut cells and beyond, including gene expression, cell differentiation, gut tissue development, immune modulation, oxidative stress reduction, and diarrhea control. Although there are a large number of studies in human medicine using butyrate to treat intestinal disease, the importance of butyrate in maintaining gut health has also attracted significant research attention to its application for animal production, particularly as an alternative to in-feed antibiotics. Due to the difficulties of using butyrate in practice (i.e., offensive odor and absorption in the upper gut), different forms of butyrate, such as sodium butyrate and butyrate glycerides, have been developed and examined for their effects on gut health and growth performance across different species. Butyrate and its derivatives generally demonstrate positive effects on animal production, including enhancement of gut development, control of enteric pathogens, reduction of inflammation, improvement of growth performance (including carcass composition), and modulation of gut microbiota. These benefits are more evident in young animals, and variations in the results have been reported. The present article has critically reviewed recent findings in animal research on butyrate and its derivatives in regard to their effects and mechanisms behind and discussed the implications of these findings for improving animal gut health and production. In addition, significant findings of medical research in humans that are relevant to animal production have been cited.
