Ultrasonic Assisted Creep Feed Grinding of Inconel 718 [PDF]

Procedia CIRP, 2013
AbstractThe paper details the effects of depth of cut and vibration amplitude when ultrasonic assisted (US) creep feed grinding Inconel 718 with an open structured alumina based wheel. The workpiece was actuated at a constant frequency (∼20.5kHz) via a block sonotrode attached to a 1kW piezoelectric transducer-generator system.

The natural diet composition of young piglets suggests an overlook of fibre and food structure in farmed suckling piglets [PDF]

Porcine Health Management
Background The often disappointing intake of creep feed by suckling piglets coincides with a limited ability to cope with challenges such as weaning diarrhoea.

An insight into the temporal dynamics in the gut microbiome, metabolite signaling, immune response, and barrier function in suckling and weaned piglets under production conditions

Frontiers in Veterinary Science, 2023
Little information is available on age- and creep-feeding-related microbial and immune development in neonatal piglets. Therefore, we explored age- and gut-site-specific alterations in the microbiome, metabolites, histo-morphology, and expression of ...

Utilization of exogenous enzymes in beef cattle creep feeds

Journal of Applied Animal Research, 2020
Two experiments were conducted to evaluate the inclusion of feed enzymes into beef cattle creep feeds. In the first one, the following treatments were tested in vitro: (1) 100% bermudagrass (GRASS); (2) a mixture of 75% bermudagrass and 25% creep feed ...

Different protocols for piglet creep feeding in the farrowing stage and residual effects in the nursery phase

Anais da Academia Brasileira de Ciências, 2022
This study was aimed at the effects of different Creep-feeding protocols on piglet performance and its residual effects during the nursery phase. Experimental design used was five groups: WC (without creep); DCF (dry creep feeding); WCF (wet creep ...
