Assessment of carcass and meat characteristics of Nellore young bulls finished in feedlot with crude glycerin levels (0, 60, 120, and 240 g kg-1 dry matter) in millet-based diets. Twenty-eight young bulls with mean age of 18 months and average weight of 357 ± 23.56 kg were used. The animals were distributed in a completely randomized design with four treatments and seven replicates. It was observed that the physical composition and edible portion of the carcass were not affected by crude glycerin levels in the diets. However, the increased dietary crude glycerin level raised the weights of the forequarters (kg and % of cold carcass weight), but not that of the pistol cut and short ribs. Among the commercial cuts prepared to marketing of the pistol cut, only the weight of the rump cap (% cold carcass weight) was changed, decreasing linearly with increasing dietary crude glycerin levels. Additionally, meat characteristics remained unaltered by the increased levels of crude glycerin. It was concluded that inclusion of up to 240 g kg-1 of crude glycerin in millet grain-based diets for Nellore young bulls finished in feedlot does not alter the main carcass and meat characteristics or affect their economic value.

Assessment of carcass and meat characteristics of Holstein-Zebu crossbred young bulls finished in feedlot with crude glycerin levels (0, 60, 120, and 240 g kg-1 dry matter) in replace of ground pearl millet grain and babassu mesocarp bran mixture-based diets. Twenty four bulls 30-month-old and initial average body weight of 390 ± 31.5 kg were used. The animals were distributed in a completely randomized design with four treatments and six replicates. The absolute weight (kg) of commercial cuts did not fit any of the tested regression models. However, the weight of the short ribs and the pistol cut were higher for animals fed with crude glycerin in relation to those fed without inclusion of this food in the diet. The proportion of the commercial cuts, however, was not changed. The increase of the crude glycerin levels linearly increased the proportion of carcass fat and reduced the muscle proportion, without changing the proportion of bone and the edible portion of the carcasses. The ratio muscle/fat reduced linearly with the advance of crude glycerin level of diets. The color of the meat, evaluated subjectively, increased linearly with the advance of crude glycerin levels of the diets, from dark red to slightly dark red. The texture, marbling, shear force, thawing loss and cooking loss were not changed by dietary levels of crude glycerin. The inclusion of up to 240 g kg-1 of crude glycerin in the diets increases the proportion of fat without changing the marketable portion of carcasses. The benefits to the meat quality refer to the improvement of color, without changing the other characteristics of economic interest.

Corn (Zea mays L.) is one of the most important cereals grown and consumed in the world not only for its economic value but also due to its importance in human and animal nutrition. This study aimed to assess the initial development of corn as a function of increasing nitrogen doses. The study was carried out in a greenhouse on the Sipal Farm, Confresa, MT, Brazil. The experiment was set up in a completely randomized design, consisting of five treatments (0, 100, 200, 300, and 400 mg N dm−3 soil), with four replications, conducted from April to June 2020. Four seeds of the hybrid K 9606 VIP 3 were sown per 8-L polyethylene pot. The plants were thinned at 7 days after emergence (DAE), leaving only one plant per pot. Morphological components were assessed. A significant effect was found for almost all the analyzed parameters, except for stem diameter and root dry matter. The maximum plant height, shoot fresh matter, leaf area index, shoot dry matter, root fresh matter, and root volume was obtained by applying the maximum agronomic efficiency doses of 248.83, 271.90, 336.91, 279.66, 403.92, and 272.90 mg N dm−3 soil, respectively. Nitrogen doses influenced the initial development of the corn crop.

Eel is one of the fisheries commodity that have not been rearing widelyin Indonesia. Constraint that occured in rearing eel is slow growth. A way to accelerate eel growth isfeeding with enrichment by using an amino acids. An amino acids can be used directly by eel for cell growth and the formation of body tissue. An amino acid that is used from the stingrays are not utilized by people  because it has no economic value to production activities. This research was aimed to study the growth rate of eel whichis fed with enrichment of an amino acids derived from stingray extract. The method in this research used completely randomized design (CRD) with 3 treatments and 3 replications. The measure of eel that usedare 26-28 cm, the average weight is 28 grams and an amino acids dosage that used are 0 ml, 0.5 ml and 1 ml. It use FR 3% which is given at night to support the characteristic of eel that is nocturnal (active at night). The analyze result from the parameters that have been observed, there is not a significant effect (P> 0.05) and the fed with enrichment by using an amino acids with the dosage used hasn't been able to be utilized as fish feed mixture to increase growth rate.

The objectives of this work were to determine the apparent digestibility coefficients (ADC) of dry matter (DM), crude protein (CP) and gross energy (GE) of coconut biscuit residues (CBR), sweet biscuits (SBR) and noodles (NR) for Nile tilapia and evaluate the performance of fingerlings fed with diets containing the residues with the highest nutritional value. In the digestibility study, 72 juveniles (with an average weight of 70.5 ± 2.7 g) were organized in a completely randomized design with three treatments and three replications (12 fish per replication). ADC was determined using an indirect method in which 0.10% chromium oxide (Cr2O3) acted as an indicator. To evaluate performance, 225 fingerlings (with an average weight of 3.4 ± 0.5 g) were distributed across 15 tanks (150 L), creating a completely randomized design with five treatments and three replications. The test diets contained 0, 4, 8, 12 or 16% CBR. ADCDM, ADCCP and ADCGE for each of the different residues were, respectively: 85, 88 and 86% for CBR; 32, 51 and 46% for SBR; 24, 31 and 26% for NR. The inclusion of CBR significantly affected final weight of the fish, specific growth rate and protein retention rate, as well as the carcass composition values for dry matter, mineral matter, gross energy and ethereal extract. CBR presents better digestibility than the other tested residues and it can be used as a substitute for maize meal in quantities up to 11.62%, thus improving fish performance.

Teripang merupakan salah satu komoditas perikanan penting dan mempunyai nilai ekonomi yang tinggi di Asia. Teknologi pembenihan teripang sudah mulai dikembangkan dan telah mampu memproduksi benih secara massal untuk budidaya. Pakan merupakan salah satu faktor yang sangat menentukan keberhasilan budidaya teripang. Penelitian ini bertujuan untuk mengevaluasi beberapa formula pakan berbasis rumput laut untuk pendederan teripang pasir. Empat pakan percobaan diformulasi menggunakan kombinasi beberapa jenis bahan baku, khususnya rumput laut. Pakan dibuat dalam bentuk pelet dengan kandungan protein 14% dan lemak 4,5%. Kontrol adalah pakan berupa bentos segar. Benih teripang pasir yang digunakan berukuran bobot 2,0 ± 0,6 g dengan panjang 2,8 ± 0,5 cm. Benih teripang dipelihara dalam bak persegi berkapasitas 150 L dengan kepadatan 50 ekor per bak. Benih teripang diberi pakan percobaan sekali dalam sehari pada sore hari. Percobaan dirancang dengan Rancangan Acak Lengkap terdiri atas lima perlakuan pakan dan empat ulangan. Percobaan berlangsung selama 120 hari. Hasil percobaan menunjukkan bahwa benih teripang pasir yang diberi pakan buatan menghasilkan pertumbuhan (pertambahan bobot 341,3%-386,8%) dan sintasan (92,5%-97,5%) lebih tinggi dan berbeda nyata (P<0,05) dibandingkan dengan yang diberi pakan bentos (kontrol), yaitu masing-masing 126,9% dan 75,0% untuk pertambahan bobot dan sintasan. Namun pertumbuhan benih teripang pada semua perlakuan pakan buatan tidak berbeda nyata (P>0,05). Kandungan protein teripang yang diberi pakan buatan (22,3%-24,4%) lebih tinggi (P<0,05) dibandingkan dengan yang diberi pakan kontrol (18,4%). Hasil penelitian ini menunjukkan bahwa benih teripang pasir dapat memanfaatkan pakan buatan dengan baik dan pakan berbasis tepung Sargassum sp. dapat diaplikasikan pada pemeliharaan benih teripang pasir.Sea cucumber is one of the important fishery commodities and has high economic value in Asia. Technology for seed production of sea cucumber has been developed and able to produce juveniles for supporting sea cucumber farming. Feed is an important factor that largely determines the success of sea cucumber farming. Therefore, this research aimed to evaluate several feed formulas based on seaweed powder for good growth performance of sea cucumber juveniles. Four experimental feeds were prepared by using a combination of several different raw materials, especially for the seaweed. The experimental feeds were prepared in pelleted form with protein and lipid content of 14% and 4.5%, respectively. Fresh benthos was used as the control feed. Juveniles of sea cucumber from hatchery with average weight of 2.0 ± 0.6 g and total length of 2.8 ± 0.5 cm were distributed into 20 of 150 L polycarbonate tanks, with a density of 50 juveniles per tank. Sea cucumber were fed the experimental feeds once a day in the afternoon for 120 days. The experiment was designed with Completely Randomized Design, with five dietary treatments and four replications. Results of the experiment showed that juvenile sea cucumber fed the artificial feeds produced significantly higher (P<0.05) growth (weight gain 341.3%-386.8%) and survival (92.5%-97.5%) than that of the control which were 126.9% and 75.0% for weight gain and survival, respectively. However, growth of juveniles among the artificial feed treatments was not significantly different (P>0.05). Protein content of sea cucumber fed the artificial feeds was significantly higher (22.3%-24.4%) (P<0.05) than that of the control (18.4%). Results of this study indicated that juveniles of sea cucumber could utilize artificial feed properly and Sargassum sp. based diet could be applied for nursery of sea cucumber juveniles.

ABSTRACT Cowpea is broadly cultivated worldwide, especially in semi-arid or arid regions where soil or irrigation water salt contents can negatively influence the species’ productive capacity. The objective of this study was to evaluate the morphophysiological responses of cowpea genotypes to irrigation water salinity. The experiment was conducted in a greenhouse, under a completely randomized design with nine replications and in a 5x3 factorial scheme. Treatments consisted of five levels of irrigation water electrical conductivity - EC (EC0: 0.55; EC1: 1.60; EC2: 3.20; EC3: 4.80 and EC4: 6.40 dS m-1), applied from the 15th day after sowing (DAS), and three cowpea genotypes (G1: BRS Imponente; G2: MNC04-795F-168 and G3: MNC04-795F-159). EC increases at 35 DAS promoted stem diameter reductions of 8.0% (G1), 11.4% (G2), and 7.7% (G3), indicating different resistance to salinity by each genotype. Leaf area reductions at 25 and 38 DAS were 30.9% and 38.8% for EC0 and EC4, respectively. The BRS Imponente cultivar presented a performance superior to those of G2 and G3 in relation to stem diameter and stem dry matter at 25 DAS, and root-shoot and root-leaf ratios at 38 DAS.

ABSTRACT Competition is the best known form of direct interference of weeds on agricultural crops. However, there is relatively little information on the competition of the weed sudangrass on soybean, which has been common in agricultural areas in the southern of Rio Grande do Sul. The objective of this study was to evaluate the competition between sudangrass and soybeans using replacement series experiments. The experiment was carried out in a greenhouse in a completely randomized design with four replications. The treatments consisted of soybean and sudangrass associations. The experimental units were 8-L plastic pots, in the proportions 0: 8, 2: 6, 4: 4, 6: 2, 8: 0, corresponding to 0, 25, 50, 75 and 100% of the crop and weed respectively. Shoot, root and total dry matter and plant height were analyzed through diagrams applied to replacement series and competitive indices. Soybean showed competitive superiority in coexistence with sudangrass in relation to shoot, root and total dry matter. The intraspecific competition was more significant for the crop and inter-specific competition was more important for the weed.

This study aimed to evaluate the Texel lambs’ meat quality fed with increasing levels of crude glycerin (0, 7, 14, and 21% of dry matter) in the diet. Thirthy-two-two non-castrated male Texel lambs were used, with initial weight of 15.9 ± 4.1 kg, using a completely randomized design with four treatments and eight repetitions, per treatment. Upon reaching the average weight of 35 kg, the animals were slaughtered. The meat chemical composition was similar among treatments (P>0.05) and total lipids and crude protein presented averages of 3.47 and 20.05 g 100g -1, respectively. No changes in pH, marbling, color, and water loss under pressure were observed. The shear force did not change among treatments and the texture can be considered soft, with average values of 5.48 kgf. There was a linear (P0.05) were observed for the attributes flavor, tenderness, juiciness, and overall acceptance among treatments. Fatty acids in higher proportions in the meat lamb were to C18:1n-9 (1298.90 mg 100g-1), C16:0 (709.07 mg 100g-1) and C18:0 (433.30 mg 100g-1), with percentages of 42.72, 23.07 and 14.35%, respectively. Significant difference according to the glycerin level in the diet was observed only for the margaric acid (C17:0) with an increasing linear effect, reaching 58.95 mg 100g-1 muscle to the group with 21% crude glycerin, corresponding to 1.77% of total fatty acids. The other fatty acids did not change, and provided a satisfactory result for conjugated linoleic acid (CLA), totaling about 6.1 mg 100 g-1 muscle, corresponding to 0.21% of total lipids. The use of glycerin in the diet for finishing lambs does not alter the characteristics of the meat, maintaining the product quality for consumption.
