“…In Costa Rica, the basis for pet food formulations is corn and soybean meal. Additionally, fish, poultry by-products, meat and bone meals (i.e., swine and cattle and other ruminants) are regularly used to supply protein and fat, which is especially practical for animals that are strictly carnivore [6]. Our data for crude protein and amino acid profiles are in agreement with other reports [48].…”

“…Pets play a particularly important role in the lives of people, including the emotional and physical wellbeing of their owners [2,3] who nowadays consider their pets as “family members” [3]. Appropriate nutrition is essential to satisfy the needs of pets effectively, ensuring their good health and long-term well-being [4,5,6]. As pet owners have become more aware of the quality of food, they feed their pet companions; commercial dry pet food has become a staple [4].…”

Costa Rican animal feed production is continually growing, with approximately 1,238,243 metric tons produced in 2018. Production-wise, pet cat and dog food are in fifth place (about 41,635 metric tons per year) amongst animal feeds, and it supplies up to 90% of the national market. Pet food production has increased as a response to the increase in the population of dogs and cats in Costa Rica, where 50.5% of households own at least one dog and indicates more responsible ownership in terms of feeding pets. Part of the process of making dry pet food involves a thermal process called extrusion, which is capable of eliminating the microbial load. However, extrusion can compromise nutritional quality to some extent by denaturing proteins, oxidizing lipids, and reducing digestibility. The objective of this study was to evaluate the quality and safety of dry pet food and to assess the effect of the extrusion process on digestibility and the quality of proteins, amino acids, and fatty acids. Pet food samples were collected before and after extrusion and were used to evaluate Good Manufacturing Practices (GMP), based on Central American Technical Regulation (RTCA 65.05.63:11). In general terms, weaknesses in infrastructure, documentary evidence, and post-process practices were observed in two Costa Rican feed manufactories. Feed safety was surveyed through the analysis of Salmonella spp., Escherichia coli, Listeria spp., Staphylococcus aureus, aerobic mesophilic microorganisms, fungi, and yeasts counts. The extrusion process effectively reduced pathogenic microorganisms, and showed no effect on the digestibility of dog food (p = 0.347), however, it could reduce the availability of some nutrients (e.g., amino acids, fatty acids). Furthermore, a retrospective diagnosis was made for puppy food (n = 68), dog food (n = 158), and cat food (n = 25), to evaluate the history of nutritional quality and safety. Finally, it can be confirmed that the correct implementation of GMP allows feed manufacturers to deliver a product of optimum texture, smell, nutritional composition, and safety.

“…Despite the importance given to the nutrient content of dog foods, there is only limited information about the digestibility of foods (Cipollini, 2008). Besides being loved and consumed by the animals, it is important to regularly analyze the dog food and also determine the quality of its nutrients declared by the food manufacturers along with the digestibility trials since the nutrient contents written on the label of food package declared by the manufacturers do not always match with the nutrient analysis (Rolinec et al, 2016).…”

This study was aimed to evaluate and compare the nutrient digestibility of grain-inclusive and grain-free commercial dry dog foods using the method of total fecal collection and also explore their effects on fecal consistency. 21 different foods, including 14 grain-inclusive (7 grain-chicken meat, 7 grain-lamb meat) and 7 grain-free were investigated. 12 adult Golden retriever dogs (age 3-4 years, body weight=22.5±1.7kg) were divided into 3 groups. The results of digestibility trials indicated that the grain-lamb meat foods showed the highest digestibility of dry matter, organic matter, and crude fiber. Overall, in the grain-inclusive and grain-free group evaluation, grain-inclusive foods showed higher digestibility of crude fibers while grain-free foods had higher ether extract digestibility whereas the differences in the scores of fecal consistencies between the groups were insignificant. Contrary to popular belief, grain-inclusive foods were more digestive than grain-free foods in terms of dry matter and organic matter. There are studies involving starch sources in the dog food formulations, but there is a need to study the digestibility of complete dog food to supply them with adequate nutrients. Also, each diet should be assessed based on its overall nutrient profile and digestibility rather than individual ingredients.

“…Laboratory analysis is the first step to assess whether a diet contains the necessary nutrients (Daumas et al, 2014). Several studies conducted the revelation of nutrient deficiencies as compared to nutrient profile requirements (Alvarado et al, 2008; Burdett et al, 2018), as well as discrepancies between values declared on the package label and results of laboratory analysis (Burdett et al, 2018; Hill et al, 2009; Rolinec et al, 2016). Therefore, more attention should be paid to the nutritional evaluation of complete dry dog foods (Zicker, 2008).…”

Dry dog and cat foods represent approximately 70% of the pet food market in the USA, with extruded foods predominating (Donadelli et al., 2019). Dry foods are popular with dog owners, because they are easy to store and provide an economical way of feeding (Daumas et al., 2014). Recent studies performed in France and Germany have shown that a high number of owners feed their dogs at least partly with commercial food, and a third to half of the owners provide dry food only (Becker et al., 2012;Colliard et al., 2006). Dry dog food is often designed as a complete diet, so it should meet the nutritional requirements of different dog breeds, ages and workloads (Case, Daristotle, Hayek & Raasch, 2011). According to the definition by the European Pet Food Industry Federation (FEDIAF, 2019) and Regulation (EC), No 767/2009 of the European Parliament and the Council, complete pet food is pet food which, due to its composition, extended period as the only source of nutrients, it will provide all
