Improvements in the welfare of animals intensive production industries are increasingly being demanded by public. Scientific methods improvement have been developed and beginning to be used on farms, including those provided precision livestock farming. The number challenges that facing is growing rapidly, farmers a key component attempts improve because their livelihood at stake. include climate change, which not only exposes heat stress but also potentially reduces forage water availability for systems. Heat-stressed reduced welfare, it important they convert feed products human consumption less efficiently, immune system compromised, both quality animals’ reproduction adversely affected. Livestock escalating fertiliser costs, may jeopardise animals. skilled labour work limited, with rural migration cities succession older uncertain. In future, high-energy protein feeds unlikely available large quantities when required expanding population.

Coffee is a renowned beverage derived from plants globally. In the coffee production process, pulp by-product that abundant in phenolic compounds. Therefore, this study aimed to assess effect of extract (CPE) on growth performance, blood biochemistry, intestinal morphology, carcass characteristics, and meat quality broiler chickens. A total 160 one-day-old male Ross 308 broilers were randomly allocated four treatments with five replicates eight chicks per replicate completely randomized design. These dietary included basal diet CPE 0 (Control), 250 (CPE250), 500 (CPE500), 1,000 (CPE1000) mg/kg for 35 days. The results showed body weight (BW) CPE500 group was significantly higher (P < 0.01) compared other groups at Moreover, increased average daily gain (ADG) = 0.004) reduced feed conversion ratio (FCR) 0.008).

Environmental stress poses serious threats to animal welfare and production, particularly in poultry, which are susceptible such stress. It can increase susceptibility diseases infections, reduce growth rates reproductive performance, behavioral issues. caused by conventional housing conditions negatively affect well-being productivity. High temperature, overcrowding, poor ventilation, insufficient lighting, wire cages some of the most prominent stressors systems. To address environmental chicken farms, strategies tools, as using anti-stress feed additives enriching cages, help improve bird activities welfare. Breeders overall performance implementing these creating a more enriched comfortable environment. Thus, this review discusses importance different enrichment materials farms (broiler layer) productivity well-being.

The effects of Enterococcus faecalis (E. faecalis) at a concentration 1.0 × 108 CFU/mL on growth performance, hepatic lipid metabolism, and mRNA expression related to intestinal morphology, flora were investigated in geese. A total 60 male geese, aged 30 days similar weight, randomly assigned 2 groups. Each group was divided into six replicates, with five geese per replicate. During the 45-day experiment, control received basal diet, while experimental provided same diet supplemented E. drinking water CFU/mL. significantly increased half-eviscerated weight improved ileal morphology (p < 0.05).

The 1:1 resveratrol–piperazine cocrystal was successfully synthesized and scaled-up to 300 g scale with the mechanochemical method, as a result of investigating key process parameters, namely solvent grinding time. use water, ethanol or ethanol–water mixtures reaction times up 50 min were evaluated relative dry process. Cocrystal formation purity monitored through X-ray diffraction calorimetry measurements. resulted in an incomplete formation, while water water–ethanol mixture yielded monohydrate solid phase. Pure found be optimal for large-scale cocrystallization, it delivered cocrystals high crystallinity after 10–30 time at laboratory scale. Notably, relatively fast (30–60 min) sufficient completion cocrystallization larger scales, using planetary ball mill plant reactor. Also, obtained increases aqueous solubility resveratrol by 6%–16% pH = 6.8. Overall, this study highlights potential solvent-assisted synthesis promising new approach efficient production pure cocrystals.
