13. Early postnatal protein malnutrition impairs recognition memory in rats (Rattus norvegicus)
The initial period of postnatal life is critical for brain development in both rodents and humans. Protein malnutrition imposed during this period produces irreversible consequences that include structural, neurochemical, and functional changes in the central nervous system, leading to long-term alterations in behavioral and cognitive parameters, such as mem

14. Validation of the gastroschisis experimental model and the influence of the mother's diet enriched with glutamine in the fetal morphology
PURPOSE: To validate the gastroschisis experimental model in female rats and the effects on the glutamine fetal morphology during pregnancy.METHODS: Twelve pregnant rats Wistar were separated in two groups: Group I (n = 6 rats, 71 fetuses) took glutamine and Group II (n = 6 rats, 75 fetuses) took isocaloric supplementation. At the 18th day of pregnancy, fema

15. Digestible threonine to lysine ratio in diets for laying hens aged 24-40 weeks
Two-hundred sixteen white laying hens were used to assess the ideal ratio of digestible threonine:lysine in diets for laying hens at 24 to 40 weeks of age. Birds were assigned to a randomized block design, with six treatments, six replicates per treatment and six birds per experimental unit. The cage was used as the blocking criterion. Experimental diets con

16. Ideal digestible isoleucine: digestible lysine ratio in diets for laying hens aged 24-40 weeks
Two hundred fifty-two Hy-Line W36 laying hens were allotted in a randomized block design with 6 treatments, 7 replicates and 6 hens per experimental unit in order to determine the ideal digestible isoleucine: digestible lysine (Ile:Lys) ratio for laying hens aged 24-40 weeks. Experimental diets contained 5.92, 6.33, 6.73, 7.14, 7.54 and 7.95 g/kg of digestib

17. Dietary crude protein reduction on growth and carcass performance of 22 to 42-day-old broilers reared under different temperatures
This study was conducted to verify the effects of dietary crude protein reduction on growth and carcass performance of 22-42-day-old broilers reared under different temperatures. Treatments were set up in a five by two factorial arrangement, with five crude protein levels (220, 210, 200, 190 and 184 g/kg) and two temperatures (21.6 and 32.2 ºC). Diets were

18. Digestible lysine levels in diets for laying Japanese quails
The objective of this study was to estimate the digestible lysine requirement of Japanese quails in the egg-laying phase. A total of 336 female Japanese quails (Coturnix coturnix japonica) of average initial age of 207 days were distributed in a completely randomized experimental design, composed of 6 treatments (lysine levels) with 7 replicates and 8 birds

19. Protein, calcium and phosphorus requirements in the maintenance of captive-bred capybaras
The objective was to determine the nitrogen-protein, calcium and phosphorus requirements of adult capybaras (Hydrochoerus hydrochaeris) bred in captivity through a nutritional balance study under conditions that favored the occurrence of cecotrophy. In a completely randomized design with four replicates per treatment, 16 adult female capybaras were fed isoca

20. Maternal protein restriction affects gene expression and enzyme activity of intestinal disaccharidases in adult rat offspring
This study investigated the consequences of intrauterine protein restriction on the gastrointestinal tract and particularly on the gene expression and activity of intestinal disaccharidases in the adult offspring. Wistar rat dams were fed isocaloric diets containing 6% protein (restricted, n = 8) or 17% protein (control, n = 8) throughout gestation. Male off

21. Utilização de resíduos de frutos e da fitase em dietas para juvenis de tambaqui, Colossoma macropomum (Cuvier, 1818) / Use of waste fruits and phytase in diets for juvenile tambaqui, Colossoma macropomum (CUVIER, 1818)
The first objective of this research evaluated the apparent digestibility of a test diet (without fruits residues) and other two, the first with an inclusion of 20% of passion fruit seeds and the other with an inclusion of 20% of peel and seeds from tucumã for tambaqui juveniles (Colossoma macropomum). The total apparent digestibility, ether extract, protei

22. Determination of digestible isoleucine: lysine ratio in diets for laying hens aged 42-58 weeks
Two hundred and fifty-two Hy-Line W36 laying hens were allotted in a completely randomized design with 6 treatments, 7 replicates and 6 hens per experimental unit in order to determine the ideal ratio of isoleucine (Ile) in relation to lysine (Lys) to laying hens aged 42-58 weeks. Experimental diets contained digestible Ile at different levels, resulting in

23. Performance and egg quality of Japanese quails submitted to cyclic heat stress
Aiming at evaluating the influence of cyclic temperatures on the performance and egg quality of Japanese quails an experiment was carried out with 480 birds after egg production peak. Birds were housed in a bioclimatic chamber with automatic temperature control that contained two rooms, one maintained at thermoneutral temperature (21 ºC) and the other adjus

24. Suplementação com análogo de metionina HMB (2-Hidroxi-4-(Metil) ácido Butânico) em dieta de bovinos da raça Nelore terminados em confinamento / Supplementation with HMB (2-hydroxy-4-(methyithio) Butanoic acid) methionine analog in diet of Nellore cattle finished in feedlot
Two experiments were conducted to evaluate the inclusion of levels of HMB (DL, 2-hydroxy-4-(methyl) botanical acid) methionine in diets of Nellore beef cattle finished in feedlot. In Experiment 1, 128 male, unneutered Nellore animals, with initial weight of 290 kg ( 20,50), were housed for 111 days (21 days of adaptation and 90 days of experiment) in 16 pens
