Weight gain and morphometric growth of genetically improved tambaqui (Colossoma macropomum)

Weight gain and morphometric growth of the genetically improved tambaqui (Colossoma macropomum) are evaluated. Current assay was carried out on the Fish Farm Experimental Station of the Federal University of Mato Grosso, in the municipality of Santo Antonio de Leverger - MT Brazil. Seven fish families from the breeding program and a control group (not genetically improved) were evaluated. All animals were individually identified with a transmitter-responder label (transponder). Weight gain, overall and standard length, head size, height, width and body perimeter were measured. A completely randomized design was used and comparisons among families and the control group were carried out by Dunnett test at 5% significance level. The genetically improved fish families showed a 14.8% higher weight gain when compared to that of control group. Five out of seven families showed greater weight gain when compared to control group, with the best family exhibiting a 24.8% higher rate. Four families had higher growth in all evaluated morphometric characteristics when compared to control group. Only one family did not differ in any of the evaluated characteristics with regard to the control group.

The objective of this study was to determine the optimal digestible threonine to lysine ratios in diets of tambaqui (Colossoma macropomum) juveniles. Five-hundred fish with a mean ± SE initial weight of 2.16 ± 0.03 g were used in a completely randomized design, consisting of four treatments, five replicates per treatment, and 25 fish per experimental unit. The treatments consisted of four isoenergetic, isophosphoric, isocalcic, and isolisinic (1.45%) diets, consisting of a basal diet supplemented with four L-threonine levels (1.013, 1.085, 1.158, and 1.230%), resulting in different threonine to lysine ratios (70, 75, 80, and 85%). Fish were maintained in twenty 500-L aquaria with independent water supply, drainage, and aeration systems, and were fed to apparent satiation six times a day for 45 days. Performance, feed efficiency, daily protein and fat deposition, body moisture content, and nitrogen retention efficiency of fish were evaluated. The digestible threonine intake increased linearly, and the efficiency of threonine for weight gain decreased quadratically, with increasing digestible threonine to lysine ratios. Weight gain, specific growth rate, feed:gain ratio, protein efficiency for weight gain, and nitrogen retention efficiency of fish increased in a quadratic manner with increasing digestible threonine to lysine ratios up to the levels of 75.96, 76.06, 76.36, 76.47, and 74.02%, respectively. It was concluded that the digestible threonine to lysine ratio for use in diets of juvenile tambaqui to achieve optimal performance and nitrogen retention efficiency is 76 and 74%, respectively, which corresponds to a digestible threonine level of 1.102 and 1.073%.

Filial Behavior

Mortality of perinatal lambs and low weight at weaning cause huge liabilities to farmers. Current study describes maternal-filial behavior and evaluates the use of maternal behavior score (MBS) to estimate the behavior of ewes and lambs soon after birth, and correlate it with lamb mortality and performance during lactation. Thirty-seven Corriedale ewes were used in a completely randomized design. MBS was assessed up to 24 hours after birth, taking into consideration the distance of the ewe from the lamb at the approach of a person. Maternal behavior, placental weight, weight gain of the lambs until weaning and their survival rate were also evaluated until two hours after lambing. More than 90% of the ewes had adequate maternal behavior, with parental care, even though ewes were very sensitive to the presence of people. There was no significant correlation between MBS and maternal behavior, lamb mortality rate and live weight gain. Under these conditions, MBS was not a useful tool to estimate maternal behavior and performance of lambs.

The seedling quality affects the plant performance in the field and proper techniques can increase the productivity of vegetables. The objective of this study was to evaluate the production of eggplant seedlings, cultivar Embu, under protected environments, containers and substrates, and its development in the field at the State University of Mato Grosso do Sul, in Aquidauana, Brazil. For seedlings production, each environment was considered an experiment, which was carried out in a completely randomized design, in split-plot scheme (containers x substrates), with eight replications. Subsequently we realized joint analysis of the experiments to compare the environments. In the field, the design was in randomized blocks using four replications. The seedlings were grown in the protected environments: greenhouse covered with polyethylene film, light diffuser, 150 micron, and nursery monofilament screen with 50% of shading (Sombrite®). Inside environments, polystyrene trays with 72 cells and 128 cells were tested. The containers were filled with six substrates, from the combination of cattle manure and cassava stems. In the field were distributed 24 treatments generated from combinations of three factors. In both environments, the best seedlings are formed in trays with 72 cells. For two trays the best seedlings are formed in the greenhouse. In greenhouse, the substrate with 80% cattle manure and 20% of cassava stems promoted better growth of seedlings. In the screened, beyond this substrate, seedlings produced in the substrate with 100% manure showed higher vigor. For all substrates, the best seedlings are formed in tray with 72 cells inside the greenhouse. In the field the combination, "greenhouse + 72 cell tray + 80% manure and 20% cassava stems" was where the plants had better growth and productivity.

The okra grows well in hot weather, finding favorable conditions for development in Brazil. We evaluated the production of okra seedlings and productivity. The experiment was conducted in the experimental area of the State University of Mato Grosso do Sul, in Aquidauana. In the seedling phase we tested substrates (100% triturated cassava stems, 75% triturated cassava stems and 25% vermiculite, 50% triturated cassava stems and 50% vermiculite, 25% triturated cassava stems and 75% vermiculite and 100% vermiculite). These substrates were placed in two protected environments (nursery with black screen, 50% of shading, and aluminized screen, 50% of shading). Each environment was considered an experiment conducted in completely randomized design with eight replications. After that we realized joint analysis. In the field, a total of 10 treatments generated from combinations of environments and substrates (2 environments x 5 substrates) were distributed in a randomized block design with four replications. The average proportions of cassava stems and vermiculite may be suitable for okra seedlings. The results of shoot and total dry phytomass indicate that the aluminized screen can be recommended for okra seedlings production when the substrate with a 1:1 ratio is used. Seedlings grown on higher percentages of vermiculite anticipate production, while seedlings produced only in cassava stems tend to slow it down. The aluminized screen tends to increase the yield of okra seedlings. Average proportions of vermiculite and cassava stems for seedling production under aluminized screen, provide more fruits and yield of okra in Aquidauana.

EFFECT OF REPLACEMENT OF CORN WITH SORGUM Cv. KAWALI IN PELLET RANSUM ON LOCAL RABBIT PERFORM. The purpose of this study was to determine the effect of substitution corn with sorghum in rabbit rations on feed consumption, body weight gain, and ration conversion. The duration of the study was 28 days using 20 local rabbits. The statistical design used in this study was a completely randomized design, with 4 (four) treatment rations and 5 (five) replications. The four experimental rations, namely R0: 45% corn + 0% sorghum, R1: 30% corn + 15% sorghum, R2 15% corn + 30% sorghum, R3 0% corn + 45% sorghum. Variables were measured, viz: feed consumption, body weight gain and ration conversion. The results showed that the average of feed consumption, body weight gain, and feed conversion, were: 28.27–30.59 g /head /day, 15.76–21.55 g / head /day, and 1.42-1.80 g /head /day, respectively. Based on the analysis of variance, the treatments ration had no significant effect (P> 0.05) on consumption, but had a very significant effect (P <0.01) on body weight gain and feed conversion. The LSD test showed that all treatment rations using sorghum (R1, R2, and R3) gave results of body weight gain which were very significantly different (P <0.01) and higher than R0. Whereas, on ration conversion, treatments R1, R2, and R3 give very different results (P <0.01) lower than R0. It is concluded that the substitution of corn with sorghum at the level of 45% in the ration gives the highest results for body weight gain and conversion of rations for rabbits.

Plants that can be used as pesticides are Gadung tubers. Gadung tubers contain cyanide acid to kill armyworm pests because they contain dioscorin toxins which can cause nervous disorders. The purpose of this study was to determine the effect of Gadung tuber extract (Dioscorea hispida) on Caterpillar mortality (Spodoptera exigua) in Shallot plants. This type of research is experimental research. This study used a completely randomized design (CRD). The sample used was 5 caterpillars (Spodoptera exigua) in each polybag with 5 repetitions for each concentration of Gadung tuber extract, namely 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%, so the total Caterpillar used was 150 Caterpillars. Gadung tuber extraction was carried out by maceration method with methanol solvent. Data were analyzed using a one-way analysis of variance at the 95% significance level, followed by DMRT (Duncans Multiple Range Test). The results showed that the Gadung tuber extract had a significant effect on the mortality of caterpillars (Spodoptera exigua) because the F count was greater than the F table (45.40>2.62), and the DMRT test results showed that the optimal concentration of Gadung tuber extract was 2.5%. Therefore, it can be concluded that the extract of Gadung tuber (Dioscorea hispida) affects the mortality of Caterpillars (Spodoptera exigua) in Shallots (Allium cepa).
