This work was carried out to evaluate the effect of dietary conjugated linoleic acid (CLA) inclusion (1.2%) on pacu performance and fillet fatty acids deposition and profile. A hundred and twelve growing pacus (256.19 ± 24.09 g of initial weight) were allotted to a completely randomized design with two treatments and four replicates, in eight tanks (1 m3 each) and hand fed to apparent satiation, three times a day, for 60 days. Extruded diet with 28% CP and 3,000 kcal […]

With the objective of evaluating the effects of the number of animals per experimental unit and the type of feeder on the nutritional requirement and carcass characteristics of pigs from 60 to 95 kg, 704 castrated male pigs with initial body weight of 59.84 ± 1.67 kg were used. The animals were distributed in a randomized experimental design subdivided into parcels, with different number of animals per experimental unit (EU) and in the subplots, a 2 × 4 factorial scheme, […]

A meta-analytical study was conducted to evaluate the performance and characteristics of the carcass of finishing pigs fed with diets containing ractopamine. Eighteen experiments containing four treatments and 2.991 animals were used. The treatments were composed of 0, 5, 10 and 20 ppm of ractopamine levels. The variables of performance and the quantitative characteristics of the carcass were analyzed. The average duration of the experimental periods was 28 ± 0.32 days. The average initial and final weights were 74.7 ± […]

This study was aimed to evaluate the effect of microbial additives containing hetero fermentative or homo fermentative bacteria on the characteristics of sugarcane silages. Sugarcane was inoculated with the following bacteria: Lactobacillus plantarum (LP), L. paracasei (LPARA), L. brevis (LBREVIS), L.buchneri (LB), isolated from sugarcane silage, and three commercial inoculants, two of them containing L. buchneri (Pioneer 11A44TM-LBP and Lalsil Cana-LBLC) and one L. plantarum (Biomax®-LPB) and control (without inoculation). All the inoculants were applied in population of 105 log […]

The effect of the addition of phytase enzyme on performance and metabolism of laying hens was evaluated. Three hundred and sixty Bovans Goldline hens were allotted to a completely randomized design, with 12 replicates of 6 birds per unit and 5 experimental treatments as follows: T1 = positive control (PC), T2 = Negative control (NC by 0.15% phosphorus available), T3 = NC + 200 FTU of phytase, T4 = NC + 400 FTU of phytase, T5 = NC + 600 […]

This study describes the differential effect of sexual reversion in tilapia strains on survival rates, growth and the percentage of phenotypical males under different environmental conditions. Two Orechromis niloticus strains (common Nile tilapia and Thai-chiltralada) and one hybrid Oreochromis sp (red tilapia) were used, which were fed from hatch during the first thirty days of life with 17-α-methyltestosterone hormone incorporated to the ration (60 mg/kg). At the 90th days, the survival rate of the common Nile had surpassed Thai-chiltralada in […]

This research was conducted with the objective of evaluating the use of different Maniçoba hay (Manihot glaziovii Muell. Arg) levels (30, 40, 50 and 60%) on intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), gross energy (GE), ether extract (EE), total carbohydrates (TCHT), non fiber carbohydrates (NFC), neutral detergent fiber (NDF), acid detergent fiber (ADF), water intake (WI), besides total digestible nutrients intake (TDNI). Eight multiparous Moxotó dairy goats with initial weight of 44,26 […]

This study aimed to evaluate the effect of the addition of two L. buchneri strains on the aerobic stability of the Mombaça grass silages. The experiment was carried out in a completely randomized design with three replicates in split-plot in time scheme, so that the treatments (silages without inoculant and with experimental or commercial inoculants) were randomized on plot and in times of aerobic evaluation of the silages (0, 2, 8, and 10 days after the opening of the silos) […]

This study had the objective of verifying the differential growth of carcass organs and visceras in relation to the empty body weight of Santa Ines and Bergamacia lambs. Thirty-six non-castrated male lambs, 24 Santa Ines breed and 12 Bergamacia breed, slaughtered at 15, 25, 35 and 45 kg of live weight under feedlot system receiving a diet with forage:concentrate ratio of 20:80 were used. The study of the relative growth of internal organs, fats, carcass non-integrant parts, carcass parts and […]

The aim of this work was to evaluate the physiological, productive and behavioral variations in Alpine goats during transportation. Twelve multiparous Alpine goats at late lactation period were used. Milk production, composition and somatic cells count, as well as the behavioral responses of goats during milking were measured in three time periods: three days before transportation, in the transportation day and three days after transportation. Also, blood samples were collected 120 min and 10 min before transportation and equal period […]
