Item Avaliação nutricional do resíduo de biscoito para a alimentação de suínos em crescimento(2021-02-26) Carmo, Matheus Rocha do; Dutra Junior, Wilson Moreira; http://lattes.cnpq.br/5594343814011398; http://lattes.cnpq.br/1116419112841949The 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.Item Efeito da utilização de diferentes promotores de crescimento sobre o desempenho de suínos nas fases de pós-desmame(2021-12-01) Souza, Andréa Silva Marques de; Lima, Tayara Soares de; http://lattes.cnpq.br/3100045021780173; http://lattes.cnpq.br/5272839332691842The objective of this work was to evaluate the effect of different types of growth promoters in the diet of pigs in nursery phase. The performance test was conducted in the Pig Farming sector of the Animal Science Department of the Federal Rural University of Pernambuco. The handling and treatment of the animals followed the guidelines of the Ethics Committee on the Use of Experimental Animals, under license number 6272191120. A total of 48 weanling pigs, from 25 to 81 days of age, were used in a randomized block design, with four treatments and six blocks representing the repetitions, the blocking factor used was the piglet weight. The treatments consisted of a reference diet based on corn and soy, without addition of antimicrobial (CO), a reference diet with the addition of antimicrobials Zinc Bacitracin/Florphenicol/Enrofloxacin (C+A), a reference diet with addition of 0 .5% organic acids (AO) and a reference diet with addition of moringa seed oil (Basal + 500ppm) (OM). For performance evaluation, daily feed intake (CRD), daily weight gain (GPD) and feed conversion (CA) were evaluated. Data were submitted to normality, homoscedasticity, and analysis of variance tests by the PROC MIXED of SAS. Duncan's test was used for the performance means, it was observed that there was no statistical difference between the promoters for the different variables tested and due to the lack of sanitary challenge in the present study, it was concluded that the addition of any would not be necessary. of these additives in the diet of the animals, since the animals that received the control diet showed the same performance as the supplemented animals.
