ArticleItem Open Access Assessment and Acceptability Evaluation of Prepared Therapeutic Pet Food for Obese Dogs(2020-01) Abinaya, A; Pasupathi, Karu; Karunakaran, R, et al.; TANUVASExtruded therapeutic pet foods of four different types for the management of obesity were prepared and stored at room temperature (30.16±1.26˚C) for 120 days. The shelf-life quality of pet foods was assessed on every 30 days by analyzing the thiobarbituric acid value (TBA), tyrosine value (TV), total plate count and yeast and mould count. The high-protein high- bre diet revealed higher TBA and TV of 2.61 mg malondialdehyde/kg and 97.46 mg/100 g, respectively, on 120th day. The pet owners’ opinion on the prepared pet food revealed that the overall acceptability of the pet food was good without any complaints. Thus, the prepared pet foods packed in LDPE bags can be safely stored up to 120 days at room temperature without any quality deterioration.ArticleItem Open Access Preparation of dry extruded pet foods and its nutrient composition(2022) Abinaya, A; Pasupathi Karu; Karunakaran, R, et al.; TANUVASThe four different dietary formulations viz., Normal diet (T1) based on AAFCO recommendations for an adult dog maintenance diet (2014), high protein high fibre diet (T2), high protein medium fibre diet (T3) and control diet supplemented with choline chloride (T4), were prepared by dry extrusion. The percentage of crude protein and crude fibre of T1, T2, T3 and T4 diet were 15.74 and 4.09; 21.90 and 11.28; 21.73 and 8.23; 15.72 and 3.99, respectively. The gross energy value (kcal/kg) of normal (T1) and choline supplemented diets (T4) were 4448.50 and 4478.50, respectively, whereas T3 and T4 were 3714.50 and 3743.50, respectively. The four therapeutic diets were extruded through BTPL twin screw extruder (Model – TSE 002, Kolkatta, India) with the extruder temperature fixed at 124 ˚C and the prepared food was conveyed through pneumatic conveyer to the drier, where the product was dried at 80 ˚C for two hours. Then, the therapeutic diets were packed in LDPE bags and stored at room temperature (30.16 ± 1.26 ˚C).
