The current feeding study was designed to validate the two dietary essential amino acid profiles(EAAP)established based on linear broken-line(LBL) and quadratic broken-line(QBL) models, in a previous study, against Evonik(AMINOhen) and breeder recommendations for ISA Brown layers for peak production(PP, 20 to 44 weeks of age), and post peak production(post PP, 44 to 75 weeks of age). The EAAP based on LBL models on average had 19.5% and 26.0% lower digestible AA(Lys, Met + cys, Thr, Trp, Ile and Val), than the EAAP based on QBL models for PP and post PP, respectively. The EAAP based on AMINOhen and breeder recommendation had lower digestible AA than QBL, and higher EAAP than LBL models for both production phases. At 20 weeks of age, 224 ISA Brown layer hens were weighed and randomly allocated to individual battery cages. Each of the four diets was replicated 8 times with 7 birds per replicate. Egg production was recorded daily, and egg weights were measured at the end of each week. Feed consumption was measured at the end of each period. The egg production rate was not significantly affected by the diets and remained at around 98.0%(PP) and 95.0%(post PP)(P > 0.05). Birds fed diets based on LBL recommendation consistently laid smaller eggs, resulting in a lower egg mass(59.8 vs. 62.0 g egg/hen per day during PP, and 60.3 vs. 63.0 g egg/hen per day during post PP; P had no significant effect on feed intake and body weight(P > 0.05). The highest feed conversion ratio(FcR) during PP(P = 0.067) and post PP(P corded for the birds offered diets based on LBL recommendation. In conclusion, all four EAAP tested in this study support an above average egg production rate. however, the EAAP based on LBL models may potentially decrease the input feed cost per kilogram of eggs but are not set to optimise FcR and maximise egg mass.

1 INTRODUcTION,This is the third Editorial/commentary that one of us(***)has written relating to boron neutron capture therapy(BNcT)[1,2].For those readers who are unfamiliar with BNcT we would refer them to several recent comprehensive reviews[3–5].The second Editorial ended on a hopeful note that with the introduction of acceleratorbased neutron sources(ABNSs),BNcT would enter into the mainstream of radiation therapy[2].

Recently, reconsidering the Rastall idea T_(μ;νν)^(v)=α_(,μ) through relativistic thermodynamics gives a new form for the scalar field α which led us to construct modern modified theory of gravity debugged ‘non-conserved gravity theory’ Fazlollahi 2023 Euro. Phys. J. c 83 923. This theory unlike other modified theories of gravity cannot directly explain the current acceleration expansion in the absence of the cosmological constant and or existence of other forms of dark energy. hence, in this study we have reinvestigated holographic dark energy Ρ_(X)~h^(2) in the non-conserved theory of gravity. In this context, the density and pressure of dark energy depend on the non-conserved term and density of the dust matter field. As shown, due to non-conservation effects on large-scale structures, unlike the original holographic model, our model onsets an acceleration epoch for the current Universe satisfies observations. Moreover, the interaction and viscous scenarios are studied for this model.
