Abstract Reduction in dietary crude protein and addition of fiber could mitigate the incidence and severity of post-weaning diarrhea, a common gastrointestinal condition in newly weaned pigs. Therefore, 360 weanling pigs, initially 5.0 ± 0.10 kg, were used to evaluate the effects of crude protein (CP) level and fiber source on growth performance and fecal microbial communities. At weaning, pigs were randomly assigned to pens and allotted to 1 of 8 dietary treatments in a 2 × 4 factorial with main effects of CP (21 or 18%) and fiber source (none, coarse wheat bran, oat hulls, or cellulose). There were 5 pigs per pen and 9 pens per treatment. Experimental diets were formulated in two dietary phases from d 0 to 10 and 10 to 24, with a common post-treatment diet fed from 24 to 45. The 21% CP diets contained 1.40% standardized ileal digestible (SID) Lys in phase 1 and 1.35% SID Lys in phase 2. By using a maximum SID Lys:digestible CP ratio of 6.35%, the 18% CP diets contained 1.25% SID Lys in both phases. Diets containing a fiber source were formulated to the level of insoluble fiber provided by 4% coarse wheat bran, resulting in the addition of 1.85% oat hulls and 1.55% cellulose. No fiber source × CP level interactions (P > 0.05) were observed. Decreasing CP (and subsequently SID lysine) decreased (P = 0.05) ADG and G:F during the experimental period. From d 0 to 45, ADG decreased (P = 0.05) for pigs fed 18% CP diets compared to pigs fed 21% CP. No effect of fiber source was observed for growth performance. Fecal DM on d 17 increased (P < 0.001) for pigs fed 18% CP diets compared to pigs fed 21% CP diets. Pigs fed diets with added cellulose had increased (P < 0.05) fecal dry matter during the experimental period compared to pigs fed no fiber source or wheat bran. Bacterial community structure was investigated by sequencing the V4 region of the 16S rRNA gene. Analysis indicated a significant difference between CP content at d 24 (P = 0.023) using a Weighted UniFrac distance matrix. Further investigation identified five differential Amplicon Sequence Variants associated with CP content at d 24. In conclusion, reducing crude protein (and subsequently SID Lys) decreased growth performance but increased fecal dry matter content. The source of dietary fiber in nursery diets had no impact on growth performance; but pigs fed added cellulose had increased fecal DM compared with other treatments. Microbial analysis identified differential taxa associated with CP content.

Abstract A total of 360 pigs (DNA 200′400, initially 5.0 kg) were used in a 45-d growth trial to determine the effects of fiber source and crude protein (CP) level in diets without pharmacological levels of ZnO on nursery pig growth performance and fecal dry matter (DM). Pigs were randomly assigned to 1 of 8 treatments with 5 pigs/pen and 9 pens/treatment. Treatments were arranged in a 2×4 factorial with main effects of CP (21 or 18%) and fiber source [none, coarse wheat bran (CWB), oat hulls, or cellulose (Arbocel, J. Rettenmaier USA, Schoolcraft, MI)]. Fiber source was added to equalize the level of insoluble fiber contributed from 4% CWB, resulting in the addition of 1.85% oat hulls or 1.55% cellulose. Diets were fed in two phases (d 0 to 10 and 10 to 24) followed by a common diet (d 24 to 45). The 21% CP diets contained 1.40% SID Lys in phase 1 and 1.35% SID Lys in phase 2. Treatment diets were formulated to a maximum SID Lys:digestible CP level of 6.35%, thus SID Lys decreased in the 18% CP (1.25% SID Lys) diets. Data were analyzed using the lmer function in R. No fiber source × CP level interactions (P >0.05) were observed. Decreasing dietary CP decreased (P = 0.05) ADG, G:F, and d 24 BW. Overall, ADG and d 45 BW decreased (P < 0.05) for pigs fed 18% CP diets. No main effects of fiber source were observed for growth performance throughout the study. Fecal DM increased (P < 0.05) for pigs fed added cellulose compared to pigs fed no fiber or CWB in the experimental period. In conclusion, reducing dietary CP decreased growth performance and the inclusion of cellulose improved fecal DM of nursery pigs.

The purpose of this study was to determine the effect of the addition of tofu waste in concentrate feed on the nutritional value of ruminant animal feed. Concentrate feed used in this study uses concentrated feed for sheep. Tofu waste was obtained from the place of making tofu in Girimarto sub-district, Wonogiri Regency. The research method used was concentrate feed for sheep given the addition of tofu waste. The study used 3 treatments namely T0 = Concentrate without the addition of tofu waste (control), T1 = Concentrate with 10% tofu waste addition, and T2 = Concentrate with 20% tofu waste addition. The results of the study were analyzed in the laboratory to determine the nutritional value of sheep feed. The study was designed with a completely randomized design. Observation parameters of nutritional value of feed include dry matter, crude protein, crude fiber and in vitro digestibility. The results showed that dry matter content was 78.54 ± 0.23% and crude protein was 16.63 ± 0.46% with the addition of tofu waste until 20% showed a significant difference, whereas crude fiber was 20.37 ± 0.48 % showed no significant difference, while the dry matter digestibility and organic matter digestibility  showed no significant difference. The conclusion of this study was the addition of tofu waste in the concentrate had an effect on the dry matter and crude protein, but not significantly different on crude fiber. The addition of tofu waste to the concentrate did not affect the digestibility of dry matter or the digestibility of organic matter.Key words : Animal feed, concentrate,  in vitro digestibility, tofu waste

The experiment was condunted at the Alfredo Volio Mata Experimental Station of the University of Costa Rica, located at 1542 meters above sea level. The purpose was to determine the effect of plant density on total forage mass and the nutritive value of corn. Three diferent plant distances were used: 30 x 70 cm, 50 x 70 cm and 70 x 70 cm resulting in 47619, 28600 and 20449 plants per hectare, respectively. The first sampling was taken out 42 days after establishment and every two weeks thereafter, until 126 days. Dry matter, crude protein, ashes, neutral detergent fiber (NDF), acid detergent fiber (ADF) and lignin were analyzed for different parts of the plant. The values for celulose and hemicelulose were calculated. Total forage mass (kg/ha) was greater at higher plant densities. Dry matter content of leaves was higher than in stems, all of the plant densities. No significant difference (P<0,05) was found for crude protein content in the different parts of the plant. ADF was always higher in stems than in leaves. Stage of growth considerably affects biomass yield and nutritional quality of fodder. Before 70 days the dry matter content in leaves was higher than in stems. Latter accumulation of dry matter in stems was greater than in leaves. Crude protein content in leaves was over 18% during the first 70 days, then decreases a level of 13% at the end of the period. The lowest value of ADF was found before 84 days in leaves and stems. Under the enviromental conditions of this experiment, it appears that plant densities of about 48000 plants per hectare are optimal.

An understanding of feed ingredient digestibility for the pirarucu is a fundamental step in the development of feeds that promote proper growth of the specie while in captivity. A digestibility trial was conducted with four treatments in triplicate (corn starch, corn, rice bran and wheat bran) to evaluate the digestibility of dry matter, gross energy, crude protein and amino acids by the pirarucu. We used indirect methodology with the inclusion of chromium oxide at 0.1% in the feeds. In total, 18 juveniles were used, with an average live weight of 235 ± 36 g. The sampled juveniles were trained to consume the feeds prior to testing. The corn and cornstarch presented the best apparent digestibility coefficients (ADCs) of dry matter, with 76.37% and 70.66%, respectively, followed by rice bran (46.23%) and wheat bran (45.13%). The best ADCs of crude protein were observed in corn (93.44%) and cornstarch (90.94%) compared to rice bran (68.23%) and wheat bran (68.58%). There was no significant difference in the ADC of gross energy; the values ranged from 47.10% for corn starch to 40.10% for corn. The corn and corn starch presented the best ADCs for all the amino acids evaluated, followed by rice bran and wheat bran.

<p>Most fish farmers in Malawi culture unimproved fish strains whose growth is slow and mature while still small. Four strains of <em>Oreochromis</em>, namely; selectively-bred/improved <em>O. shiranus</em> (F<sub>8</sub>), two reciprocal F<sub>1</sub> <em>Oreochromis</em> hybrids, and <em>O. karongae</em> as a control (mean weight 2.5 ± 0.7 g) were stocked at a density of 5fish/m<sup>2 </sup>in 9m<sup>2 </sup>hapas replicated three times, and cultured for 90 days at Bunda Fish Farm. Fish were fed twice a day with feed formulated using maize bran and soybean containing 30% crude protein throughout the experimental period. The final mean weights were significantly different (p&lt;0.05) across the treatments whereby; hybrid <em>O. shiranus</em> (male) X <em>O. karongae</em> (female) was 12.09g, hybrid <em>O. shiranus</em> (female) X <em>O. karongae</em> (male) was 9.72g, improved <em>O. shiranus</em> (F<sub>8</sub>) registered 9.23g, and <em>O. karongae</em> was the least with 9.00g. Apparent food conversion ratio was also statistically different (p&lt;0.05) across the treatments whereby; <em>O. karongae</em> was 3.63, hybrid <em>O. shiranus</em> (female) X <em>O. karongae</em> (male) was 3.25, improved <em>O. shiranus</em> (F<sub>8</sub>) was 3.16 and hybrid <em>O. shiranus</em> (male) X <em>O. karongae</em> (female) was lowest with 2.26. There were no significant differences on the water quality parameters across the treatments throughout the experimental period and were within the required ranges for growth and survival of tilapias fish species. The results suggest that <em>Oreochromis</em> hybrids may be suitable candidates for aquaculture in terms of production as they performed better than the improved <em>O. shiranus</em> and the control <em>O. karongae</em>.</p>

Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.

A estrutura da pastagem é uma característica determinante tanto da dinâmica de crescimento da planta quanto do comportamento ingestivo dos animais. O objetivo do trabalho foi descrever a densidade da forragem e a proporção dos componentes morfológicos da planta, nos estratos verticais de pastagens de capim Marandu, submetido ao pastejo em diferentes alturas. O delineamento utilizado foi o inteiramente casualizado e as análises de variância e de regressão. Durante o experimento, as alturas médias dos seis piquetes utilizados foram de 10, 17, 18, 29, 32 e 50 cm. O material coletado foi separado, em lâmina foliar, colmo verde e material morto, que foram analisados quanto ao teor de matéria seca, proteína bruta e fibra em detergente neutro. Os estratos verticais apresentaram diferentes composições em relação aos componentes morfológicos de acordo com a altura do pasto. Os estratos próximos ao solo apresentaram maior densidade de forragem com valores de 370 a 543 kg/ha.cm, maior proporção de colmos verdes (30 a 53%) e material morto (25 a 52%) e menor de lâminas foliares (10 a 35%). Independente da altura do pasto, os estratos superiores são mais sensíveis aos efeitos do animal e do ambiente, e apresentaram maiores teores de PB e FDN para lâminas foliares e colmos. Nos estratos acima de 15 cm, os valores de PB e FDN das lâminas foliares verdes variaram entre 10,3 e 13,6% e 49,3 e 54,2%, respectivamente. O manejo em diferentes alturas altera as características dos estratos verticais do pasto, principalmente, nos estratos acima de 15 cm.   Palavras-chave: Altura do Pasto. Densidade Forrageira.

The objective of the work was to describe the density and the proportion of the plant’morphological components, in the pastures vertical strata of Marandu grass, subjected to grazing at different heights. The design used was completely randomized and the analysis of variance and regression.  During the experiment, the average heights of  six paddocks used were 10, 17, 18, 29, 32 and 50 cm. The collected material was separated into leaf blade, green stem and dead material, which were analyzed as to the dry matter content, crude protein and fiber in neutral detergent. The vertical strata presented different compositions in relation to the morphological components according to the height of the pasture.  The near-soil strata showed higher forage density with values from 370 to 543 kg/ha.cm, higher proportion of green stems (30 to 53%) and dead material (25 to 52%) and smaller number of leaf blades (10 to 35%). Regardless of the height of the pasture, the upper strata are more sensitive to the animal and the environment effects, and presented higher levels of CP and NDF for leaf blades and stems.  In the strata above 15 cm, the values of PB and NDF of the green leaf blades varied between 10.3 and 13.6% and 49.3 and 54.2%, respectively. The management of different heights change the characteristics of the pasturevertical strata, mainly in the strata above 15 cm.   Keywords: Height of the Pasture. Forage Density. Green Stems.

The average data for 2018–2019 are presented for yield, dry matter content in grain-haylage mass, nutritional value of test grain-haylage samples produced from plant mass of white lupin, oat and Sudan grass from single and mixed cenosis of different sowing times. The grain-haylage mass was harvested in the phase of brilliantly ripening lupin bean, milky-waxy ripeness of oats and the end of flowering of the Sudan grass. It’s revealed that variants of the second sowing date — 2 decade of May — have the best yield of grain-haylage mass and its dry matter content. The yield of grain-haylage mass in the best variants of the second sowing period exceeded by 7–8 t/ha. According to the nutritional value of grain silage samples (the content of metabolic energy, crude protein, crude ash and carotene), the best results were obtained in most variants of the first sowing period. In content of the metabolic energy and crude protein of 1 kg of dry matter of grain-haylage, the best were variants of the single-species cenosis of lupine and its mixture with oats of the first sowing period. Variants of single-species sowing of lupine and Sudan grass were distinguished by the content of carotene.
