Paulino valdinei_paulino@yahoo.com.br <p>It was aimed in this study to evaluate the ensiled pejibaye&nbsp; residue in the feeding of ruminants as roughage. For the <em>in vitro</em> digestibility assay, a randomized block design was used, with four treatments (pejibaye residue without additives; pejibaye residue + banana residue; pejibaye residue + rice residue and pejibaye residue + citrus pulp), with four replications. The variables studied were: chemical composition, specific mass, pH, average particle size, fermentation temperature and fermentative losses. Apparent digestibility was performed with sheep in a completely randomized design, to evaluate the same treatments mentioned above, using five replications. Heart-of-palm pejibaye residue silages showed average particle size, pH and density values within the range appropriate for their manufacture. Among the additives used in this study, silage with 15 g/100g of rice provided improvements in several nutritional parameters, such as DM, NDF, ADF, CF and NDF/NFC. High moisture content impairs the ensiling process, but it was solved with high dry matter content ingredients addition to promote the material stability.</p> 2021-01-29T17:38:00-02:00 ##submission.copyrightStatement## http://iz.sp.gov.br/bia/index.php/bia/article/view/1716 Teeth wear of piglets in lactation phase: performance and injuries aspects 2021-02-01T09:31:21-02:00 J. Tasca julitasca@outlook.com B. P. Santarosa biancasantarosavet@gmail.com H. B. Hooper hoopervet@gmail.com S. R. S. Surian soraya.surian@ifc.edu.br <p>Piglets are born with a total of eight teeth and on the second day of life, teeth wear management is carried out to avoid lesions on the sows' ceilings and on the faces of the piglets. For this, an electric wearer is used that only wears the apex of the teeth. In this experiment, a comparison of twelve litters divided into: a control group (CG) was performed, which the intact teeth were kept ; with the management of tooth wear and treatment group (TG). The animals were followed from the first day of life until weaning.&nbsp; The weighing was carried out on the respective days of life: second, seventh, fourteenth and twenty-first. It was observed that the fights between piglets and for the ceilings did not present significant difference, on the other hand the injuries caused by the teeth and the dirt injuries had significant difference with greater presence in the group without wear. In the comparison of the piglets’ daily weight gain, there was noted that no significant difference between two groups was observed, which can state that the non-wear of the teeth does not interfere in the daily weight gain, however it was concluded that the animals without wear (CG) had a higher incidence of dirt lesions.&nbsp;</p> 2021-01-29T17:47:37-02:00 ##submission.copyrightStatement##
