Performance of growing lambs supplemented with ground licuri (Syagrus coronata)
Daza Adin,Souza Jocely G.,Monnerat Joao Paulo I. S.,Ribeiro Claudio V. D. M. 아세아·태평양축산학회 2021 Animal Bioscience Vol.34 No.6
Objective: The aim of this study was to determine the effect of dietary ground licuri on lamb performance. Methods: Forty male lambs were used in a completely randomized design to test the effects of 0, 5, 10, and 15 g/kg of ground licuri added to diets. The trial lasted for 75 days. Intake, digestibility, physically effective neutral detergent fiber, and chewing activity were estimated. Blood samples were taken on day 45 to determine the concentrations of glucose, urea, nonesterified fatty acids, and triglycerides. Average daily gain (ADG) were determined on the last day of the experimental trial. Results: Licuri inclusion markedly increased dietary neutral detergent fiber and ether extract (EE) content, but it decreased dry matter (DM) intake. However, the intake and digestibility of EE linearly increased. The ADG decreased linearly (p<0.05) with licuri inclusion. Licuri had no effect (p>0.05) on the concentrations of blood metabolites; however, blood urea increased (p<0.05), while serum glucose decreased (p<0.05). Conclusion: The physically effective fiber of ground licuri is similar to Tyfton hay and licuri inclusion decreases lamb performance due to a decreased in DM intake.

The shoot borer, Hypsipyla grandella Zeller, is a Lepidopteran that practically covers the entire Brazilian territory. Its damage to mahogany is so intense that it can prevent establishment of commercial plantations of the species. Studies of its control are critical for mahogany planting in different regions to be feasible and sustainable. To conduct bioassays and studies of this insect's biology, mass rearing is necessary. This study aimed to develop a method of mass rearing based on a diet of mahogany seeds. Caterpillars arising from mahogany populations located in Brasilia, Brasil were placed in plastic containers containing mahogany seeds. Morphological and morphometric aspects were evaluated through eight successive generations. The mahogany seeds produced a good supply of quality insects for performance of bioassays, with uniform sizes and weights for each instar and a low adult deformation rate.

Effects of Castor Meal on the Growth Performance and Carcass Characteristics of Beef Cattle
Diniz, L.L.,Filho, S.C. Valadares,Campos, J.M.S.,Valadares, R.F.D.,Da Silva, L.D.,Monnerat, J.P.I.S.,Benedeti, P.B.,De Oliveira, A.S.,Pina, D.S. Asian Australasian Association of Animal Productio 2010 Animal Bioscience Vol.23 No.10
The purpose of this study was to evaluate the effect of replacing soybean meal with treated castor meal with (CMT) or without lime (CMNT) on the nutrient intake, performance, carcass characteristics, and yield of commercial cuts of beef cattle from a feedlot. Thirty male, castrated, crossbreed zebu cattle were used in the study, with an average initial weight of $360{\pm}30.27\;kg$. Five animals were used as a control group and were slaughtered at the beginning of the experiment; the remaining animals (n = 25) were distributed in random blocks (repetitions), with body weight as the criterion for block assignment. The animals were fed a diet containing 65% corn silage and 35% of concentrate on dry matter (DM) basis. Five diets consisted of four levels of soybean meal (SM) substituted with CMT (0, 33, 67 and 100%) on a DM basis and a diet with 100% of SM replaced with CMNT. At the end of the experiment, all animals were slaughtered, and their gastrointestinal tracts were emptied to determine their empty body weights (EBW). No significant effects were observed (p>0.05) for the substitution of soybean meal with CMT on intake of dietary nutrients, the average daily body weight gain (ADG) or EBW gain (EBWG). In spite of greater (p<0.05) ricin intake for the diet containing CMNT (3.06 mg/kg BW) compared to the CMT diet (0.10 mg/kg BW/d), there were no effects (p>0.05) on intake of dietary nutrients, ADG or EBWG. The average intake of DM and the ADG were 10,664.63 and 1,353.04 g/d, respectively. Regarding carcass characteristics, only carcass yield in relation to body weight was linearly reduced (p<0.05) upon substitution of SM by CMT. There was no effect (p>0.05) of the substitution of SM by CMT or CMNT on the yield of carcass basic cuts. CMT prices that are higher than 85% of the SM price do not economically justify the use of CMT. For CMT prices between 20 and 80% of the SM price, the optimal level was 67% substitution, while for prices below 15% of the SM price, the optimal level was 100% substitution with CMT. It can be concluded that treated castor meal with 6% lime can totally replace soybean meal in beef cattle diets.
