In this context, the present study aimed to characterise the adsorption and desorption curves of extruded dry foods for dogs and cats using the Guggenheim-Anderson-De Boer (GAB) model, as well as to compare these results with those obtained from a simpler and faster method, the drying curve. Three foods for dogs and three for cats were evaluated. The equilibrium moisture content by isotherm method was determined at 30°C using the gravimetric method with six saturated saline solutions, covering aw from 0.11 to 0.83. The isotherm curves between aw and moisture content were plotted by GAB model. The drying curve for each food was plotted between aw and moisture using direct data obtained during the drying of samples after extrusion in an air oven at 60°C, to compare this result with the desorption curve. The parameters for each curve using the GAB model were determined using RStudio software. To compare the drying curves with the sorption isotherm, the Wilcoxon paired t-test was used. All pet foods exhibited a type II isotherm. The average R2 was 0.99 for the adsorption curves, 0.87 for desorption and 0.99 for drying curves, showing a good fit of the models. The adsorption and desorption isotherms, as well as the drying curves, showed different predicted equilibrium moisture contents, with higher values predicted by the desorption method. In conclusion, the adsorption curves were the most suitable for the dry pet foods evaluated, and the drying curve could not be recommended due to the lower accuracy compared to the sorption isotherms.","PeriodicalId":14942,"journal":{"name":"Journal of Animal Physiology and Animal Nutrition","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146112794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A proof-of-concept trial with a commercial dry renal diet was conducted in 33 healthy cats to assess its palatability over three consecutive 6-day phases: acceptance (renal diet only), control (usual food only), and preference (both foods simultaneously). The first two phases used the one-bowl test, whereas the third used the two-bowl test methodology, with latency time, food intake, and behavioural patterns being recorded by the caregivers at home. During the acceptance phase, caregivers classified it as good/very good, bad/very bad, or normal in 60.6%, 24.2%, and 15.2% of cats, respectively. Cats over 6 years, those weighing ≤ 4.9 kg, females, and those accustomed to have food available all day showed a lower median renal diet intake. Among the 29 cats that finished the one-bowl test, only four cats showed significant differences in food consumption: two ate less and two ate more renal diet compared with their usual food. Latency time and food-related behaviours did not differ with the food. Thirty cats completed the two-bowl test, with 43.3%, 43.3%, and 13.3% reportedly preferring the renal diet, their usual food, or neither in particular, respectively. Overall food intake ratios did not differ significantly, although 12 and 8 cats consumed significantly more and less renal diet, respectively. The variables 'first approached' and 'first eaten' showed a significant association in the third phase. In most cases (83.3%), the renal diet would likely/very likely be offered again if recommended. These findings suggest that this commercial renal diet was not less palatable than most of the maintenance foods used as control, reinforcing that its acceptance in CKD cats may depend more on clinical status than food palatability.","PeriodicalId":14942,"journal":{"name":"Journal of Animal Physiology and Animal Nutrition","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146029577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distinction between organic phosphate (oP) from feed ingredients and Pi with standard laboratory methods is impossible. Most Pi sources are highly soluble after 1 min in water (Psol1). Measuring fractions of P according to solubility by the method of Lineva et al. (2019) can be used to estimate Pi addition. Heat processing reduces the fraction of Psol1 in meat. The aim of this study was to investigate the effect of heat- and pressure processing on complete wet diets with Pi addition. An experimental cat diet with loaf-type consistency was prepared. One sample without additives, one with a complete mineral-vitamin premix without Pi to balance and 16 samples with such premixes plus Pi addition from four different commonly used sources (H3PO4, NaH2PO4*H2O, KH2PO4, CaHPO4) were tested in various combinations and concentrations. Ca/P ratios were adjusted in ranges between 1/1 and 2/1 and for three samples above 2/1. Part of the samples was kept raw and stored frozen, the rest was canned individually according to specifications common for the canning process. The samples were analysed by the method of Lineva et al. (2019), measuring fractions of soluble P in water and 0.4% HCl after 1 and 90 min in raw and canned samples. The results showed a strong correlation between Pi addition and measured amount of Psol1 in the raw samples. However, Psol1 strongly decreased in the identical canned samples. High amounts of Psol1 are found in commercial pet food. The findings of this study indicate that the amount of added Pi in commercial pet food is probably even higher than can be expected by measuring Psol1.","PeriodicalId":14942,"journal":{"name":"Journal of Animal Physiology and Animal Nutrition","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145849805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
