Nutritional improvements in intensive aquaculture production systems is necessary for the reduction of stress, maximum utilization nutritional components, and expression genetic potential fish. The objective this study was to evaluate hemato-immunological, histological parameters gut microbiota Nile tilapia fed with microalga Schizochytrium sp. Males were distributed among eight net cages (6 m3), 105 days two diets: control (CON), without sp., supplemented (SUP), 1.2% diet. final weight,...
1. Two experiments were performed to study the supplementation of valine, isoleucine, arginine and glycine (Val, Ile, Arg, Gly) in low-protein diets for broiler chickens starter (1-21 d; Exp. 1) grower (22-42 2) phases. 2. A low-crude protein (CP) diet was formulated meet requirements all amino acids (AA) supplied by control except Val, Arg Gly. The other experimental obtained isolated or combined studied AA low-CP diet. 3. Growth, serum parameters litter characteristics taken both...
A study was conducted to evaluate Gly requirements in low-CP diets with different levels of digestible (dig) Thr, and their effects on performance, intestinal mucosal development, nutrient utilization broiler chickens from 21 35 d age. total 240 twenty-one-day-old Cobb-Vantress male were distributed a completely randomized 4 × 2 factorial arrangement for 8 treatments 5 replicates 6 birds each.

Genetically improved farmed tilapia (GIFT) is a strain of Nile ( Oreochromis niloticus ) developed for production and commercial parameters. Skin color, one the characteristics distinguishing varieties, an important phenotypic trait associated with qualitative productive performance. This study aimed to assess fillet skin in GIFT black red phenotypes. For this, 24 from same spawning stock were divided into two groups based on namely variety (dark skin) (reddish skin). There no significant...
Was evaluated the pattern of growth among females and males tambaqui by Gompertz nonlinear regression model. Five traits economic importance were measured on 145 animals during three years, totaling 981 morphometric data analyzed. Different curves adjusted between for body weight, height head length only one curve was to width length. The asymptotic weight (a) relative rate maturity (k) different sexes in with ± 5 kg; slaughter practiced a specific niche market, very profitable. However,...
This study evaluated the performance, prevalence of ectoparasites and morpho-functional response liver branchiae Nile tilapia (Oreochromis niloticus) raised on fish meal with added homeopathic complex Homeopatila 100(®) at different concentrations.Post-reversed juvenile (O. GIFT (Genetic Improvement Farmed Tilapia) strain were used in this study. The ectoparasite parasite load skin as well branchial histology. Fish randomly assigned to receive one four treatments: control, 20 mL...
Phenotypic characters of honeybees, relevant to beekeepers, can be evaluated by studying correlations between them, and the correlated characteristics in short term assist monitoring annual genetic progress. This work therefore aims evaluate production honey propolis, hygiene defensive behaviours two generations Africanized Apis mellifera (Hymenoptera, Apidae), estimate them their heritability. We used 30 Langstroth beehives apiaries Marechal Cândido Rondon, Paraná State, Brazil. a method...
Abstract Digital image analysis is a practical, non‐invasive, and relatively low‐cost tool that may assist in the evaluation of body traits Nile tilapia, being particularly useful for assessing difficult‐to‐measure variables, such as areas. In this study, we aimed to estimate variance components genetic parameters areas tilapia obtained by digital images. The data set comprised weight (BW) records 1,917 pond‐reared fish at 366 days age. Of total, 656 animals were photographed subjected trunk...
A analise da morfologia dos espermatozoides do semen colhido de 30 pacus (Piaractus mesopotamicus) consistiu tres solucoes fi xadoras: formol salina tamponada (FS), citrato sodio diidratado a 3% (CS) e agua destilado (Ag) para corar as celulas espermaticas corantes: Vermelho Congo (VC), Rosa Bengala (RB) Williams-modifi cado (WM). As combinacoes corantes xadoras utilizadas foram: RB X FS, WM VC Ag, CS CS. Na avaliacao esfregacos levaram-se em consideracao alteracoes anatomicas, efi ciencia...
The influence of the age Japanese breeder quails was studied by analysis fertility and sperm-egg interactions on perivitelline layer fertile eggs along reproductive lifetime. Thus, 10 quail couples were observed every 30 d from 70 to 430 d. In each analyzed period, males remained with females for 24 h, oviposited up laying 3 consecutive infertile eggs. examined, their number sperm (sptz)adhering outer over germinal disc determined expressed as sptz/mm(2). had no effect (P > 0.05) maintenance...
The main factor considered in breeding programs for fish is growth, which can be assessed terms of a gain either weight or body measurements. This study was undertaken to evaluate the morphometric traits GIFT strain tilapia (Oreochromis sp.) selected gain. data set used contained information on 6,650 animals. genetic values 8,590 animals relationship matrix five generations were predicted. following measurements evaluated: standard length; depth and width. Body area volume also calculated....
Weight gain and morphometric growth of the genetically improved tambaqui (Colossoma macropomum) are evaluated. Current assay was carried out on Fish Farm Experimental Station Federal University Mato Grosso, in municipality Santo Antonio de Leverger - MT Brazil. Seven fish families from breeding program a control group (not improved) were All animals individually identified with transmitter-responder label (transponder). gain, overall standard length, head size, height, width body perimeter...

Heritability estimates low measured (0.10 0.19) moderate high (0.23 0.81). Common full-sib effects (>73%),...
An algorithm to perform mate selection in aquaculture breeding using a computational optimization procedure called "differential evolution" (DE) was applied under optimum contribution and scenarios, assess its efficiency maximizing the genetic merit while controlling inbreeding. Real data sets with 8,782 Nile tilapias from five generations 79,144 coho salmon eight were used optimize objective functions accounting for coancestry of parents expected inbreeding future progeny.
