The objective of this study was to evaluate the residue of the cookie industry for growing pigs. A physical-chemical analysis of the cookie waste (RB) was performed to determine its composition, then a digestibility trial was developed to determine the digestibility coefficients of dry matter (DM) and crude protein (CP). For this, 16 castrated male Landrace x Moura crossbred pigs were kept in metabolism cages, grouped in an entirely randomized design with two treatments (control diet and diet with 40% cookie waste substitution), eight repetitions and one animal per experimental unit in the growth phase (mean initial weight of 34.68 ± 4.14 kg). The experimental period consisted of 14 days, with the first 7 days for adaptation to the cage and feed, and the last 7 days for collection. During this period the animals received water and feed twice a day. Dry matter digestibility, crude protein digestibility and digestible protein were evaluated. The cookie residue presented 90.47% DM, 4.59% CP, 14.80% EE, 1.94% CZ. The gross energy of the cookie residue was 4061 kcal/kg, while the DP was 90.61%. The apparent digestibility coefficients of the cookie residue showed 94.24% CDAMS and 90.21% CDAPB. The results of chemical composition and nutrient digestibility allow us to conclude that the industrial cookie residue has the potential to be used in the feeding of growing pigs.

The objective of this experiment was to find correlation values between the body measurements for the weight measurement of the animals, since this will facilitate a measurement of the weight gain of the animals for the producers who do not have access to a scale. The experiment was conducted in the swine sector of the Animal Science Department of UFRPE. Eighteen male castrated animals of the Piau breed, with average initial weight of 100 kg, were housed in individual bays. The weighing and measurements were performed every fortnight, the data were submitted to Pearson test: thoracic perimeter (TP), body length (BL), head length (HL), neck length (NL), and a sum of the thoracic perimeter and body lenght (TP+BL). It was found strong and positive correlations with body length and thoracic perimeter with body weight (0.72 and 0.74), the head length presented moderate and positive (0.65) correlation, followed by neck length that showed weak correlation (0.31) with body weight. When it was used the sum of two measurements it was found a stronger correlation with body weight (0.93), indicating that this way is more efficient to predict the animals body weight than one measure alone (TP or BL)
