The effects of body weight or age and dietary digestible lysine and metabolizable energy on apparent digestibility of energy and dry matter were evaluated in piglets after weaning. The animals were weaned at 21 days of age and distributed in two groups: 8.68 ± 0.76 kg at 28 days of age (weaned 7 days earlier); and 12.73 ± 0.99 kg at 35 days of age (weaned 14 days earlier). The pigs were allotted in digestibility cages in a completely randomized block design with the following factorial arrangements: 2 × 4 composed of two weight categories and four levels of digestible lysine (1.222; 1.305; 1.390 and 1.497%); and 2 × 3 composed of two weight categories and three levels of metabolizable energy (3,510; 3,700 and 3,830 kcal/kg rations). Digestible lysine was evaluated in six replications and metabolizable energy in eight replications and each animal constituted an experimental unit. Piglets with higher body weight and age were more efficient in nitrogen retention and energetic balance, compared to lighter and younger piglets, particularly those given lower concentration of lysine in the diet. The energy increase favored nitrogen retention by the heavier and older piglets. However, coefficients of dry matter and energy apparent digestibility did not differ among weight categories. Older and heavier piglets were more efficient in nitrogen retention, although this efficacy depended on concentration of the energy in the diet. This better use of protein and energy suggest differences on nutritional requirements.

Ensilage Corn

The objective of this study was to evaluate different textures and storage forms of corn in piglet diets. Two experiments were conducted, one of which tested digestibility of nutrients and the other diet performance. In the digestibility trial, 24 crossbred (Landrace X Large White) barrows with an initial weight of 18.7 ± 1.5 kg were used. They were kept in metabolic cages in a randomized block design using the factorial arrangement 2 X 2 (type of corn - dent and flint X type of storage - moist grain silage and dry grain) and six replicates, with one animal as the experimental unit. The values of metabolizable energy (ME) obtained were 3841 kcal of ME/kg of dry matter (DM) from dry corn, 3912 kcal of ME/kg of DM from moist corn, 4022 kcal of DM from ensiled dry corn and 3928 kcal of ME/kg of DM from ensiled humidity corn. The ensilage process increases the digestibility coefficient of dry matter and crude protein and increases the digestible energy of the diets, independent of the process form. The type of corn did not influence these variables. In the performance trial, 60 barrows (initial weight of 6.5 ± 1.5 kg) of the same stock were used during 28 days of post-weaning distributed in the same experimental design, with five replicates and three animals as the experimental unit. The treatments did not influence the daily weigh gain or the daily feed intake. The dentate corn and the ensilage process decreased the feed conversion of the independent form (no significant interaction). The substitution of dry for ensilage corn increased the digestibility of the nutrients in the diets and the feed conversion of the piglets from 7 to 15 kg. Dentate corn promotes best feed conversion in this phase.

SUMMARY1. A split-plot design was used to study apparent digestibility of dry matter, gross energy and nitrogen of a whole grain wheat diet and processed (hammermilled, rolled or hammermilled and then steam-pelleted) wheat diets by eight small (33·9 ± 0·1 kg) and eight large (70±1·7 kg) pigs. Metabolizable energy and nitrogen retention were also studied with the small pigs.2. The processed wheat diets were superior to the whole grain wheat diet in all the parameters measured.3. There were no significant differences between the performance of pigs given the differently processed wheat diets.4. Apparent digestibility of dietary components particularly in the whole wheat diet was significantly higher when diets were given to small pigs than when given to large pigs.

The proximate and mineral constituents of six plantain forms, raw green plantain (RGP), cooked green plantain (CGP), raw ripe plantain (RRP), cooked ripe plantain (CRP), green plantain meal (GPM) and ripe plantain meal (RPM) were determined by chemical analysis. 24 large white barrows, weighing initially, between 40-45 kg., were used to study the apparent digestibility of nutrients, digestible energy (DE), metabolizable energy (ME), metabolizable energy corrected for nitrogen retention (ME(n) and total digestible nutrients when the plantains served as the only source of nutrients. In a second experiment ME and ME(n) were measured for the plantain forms using 28 Large White barrows, with diets in which the plantains replaced 50% of maize in a basal diet. All the plantain forms had low fat, crude fibre and crude protein content but high in nitrogen-free extract, phosphorus, potassium and Iron. Identically high dry matter (D.M.) and nitrogen-free extract (N.F.E.) digestion coefficients were obtained for all the plantain forms except RPM, which had significantly lower values. Digestion coefficients for crude protein (46.9, 53.6, 51.8, 34.3,-32.7 %), crude fibre, (46.6, 49.5, 58.7, 62.6, 56.9, 39.6 %), ether extract (55.9, 56.6, 66.9, 69.2, 54.7 and 34.6 %) for RGP, CGP, RRP, CRP, GPM and RPM respectively were considerably lower than for D.M. and N.F.E. The DE, ME ME(n) and TDN values were comparable for all plantain forms except RPM, which had significantly lower values in most cases. The fresh green plantains and green plantain meals had slightly higher energy values than the ripe plantains, even though the nutrients in the ripe plantains were better digested than in the green forms. The results are discussed in relation to variations in the relative proportions of the simple and more complex carbohydrates during ripening.

A research aimed to evaluate nutrients digestibility in growing local male pig fed spontaneous bioconverted-tamarind seed has been done in animal feed technology laboratory of Kupang State Agricultural Polytechnic.The research used 25 local male grower pigs with body weight around 3-6 kg. The study used a randomized block design with five treatments, i.e. R0 = ration using tamarind seeds without bioconversion, R1 = ration using spontaneous bioconversion tamarinds for 24 hours, R2 = rations using spontaneous bioconversion tamarinds for 48 hours, R3 = rations using bioconversion tamarinds spontaneous for 72 hours, and R4 = rations using spontaneous bioconversion tamarinds for 96 hours. Each treatment was repeated five times in which each of them used five pigs. Parameters observed were nutrient digestibility (dry matter, crude protein, crude fat, crude fiber, and ash). The data were analyzed by using variance and continued by Duncan’s multiple range test to determine the differences between treatments. The results showed that the time of spontaneous bioconversion of tamarind seeds increased the digestibility of tamarind seed nutrients and it was concluded that the best time of spontaneous bioconversion was for 72 hours.

Zeolites are hydrated crystalline aluminosilicate minerals of natural occurrence, structured in rigid third dimension net that can be used as slow release plant-nutrient source. The main objective of this study was to evaluate the effects of plant growth substrate under zeolite application, enriched with N, P and K, on dry matter yield and on nutrient contents in consecutive crops of lettuce, tomato, rice, and andropogon grass. The experiment was carried out in a greenhouse, with 3 kg pots with an inert substrate, evaluated in a randomized block design with three replications. Treatments consisted of four types of enrichment of concentrated natural zeolite: concentrated zeolite (Z) only, zeolite + KNO3 (ZNK), zeolite + K2HPO4 (ZPK) and zeolite + H3PO4 + apatite (ZP), and a control grown in substrate fertilized with a zeolite-free nutrient solution. Four levels of enriched zeolite were tested: 20, 40, 80, and 160 g/pot. Four successive crops were grown on the same substrate in each pot: lettuce, tomato, rice, and andropogon grass. Results indicated that N, P and K enriched zeolite was an adequate slow-release nutrient source for plants. The total dry matter production of above-ground biomass of four successive crops followed a descending order: ZP > ZPK > ZNK > Z.

AbstractThe morphological development of the sheep and the goat is different and this difference is manifested from early post-natal life. The main characteristic of kid goat carcasses is their low adipose tissue, and this is considered detrimental to quality. In an attempt to determine the nutritional causes of this, a study was performed with kid goats of the Granadina breed and lambs of the Segureña breed. Six kid goats and six lambs were slaughtered at birth, while a further eight kids and eight lambs were fed a milk replacer to satiety until the 60th day of life and slaughtered on the 61st day. Dry matter (DM) and metabolizable energy (ME) intakes and apparent digestibility of energy were determined in four balance periods between 8 and 60 days of life. From the intakes of ME and comparative slaughter data it was possible to calculate energy retention (ER), heat loss (HL) and energy retained as protein (ERp) and as fat (ERf) for kids and lambs. Kid goats showed a similar apparent digestibility of energy to lambs but had lower DM and ME intakes per kg metabolic body weight (M0·75) than lambs. For kids and lambs respectively these values were: 0·93 and 0·94; 45·4 and 50·1 g/kg M0·75 per day; 937 and 1033 kJ/kg M0·75 per day. Mean values for ER, HL, ERp and ERf rates were: 263, 674, 131 and 132 kJ/kg M0·75 per day for kid goats and, 343, 690, 132 and 211 kJ/kg M0·75 per day for lambs. Together with the different intake, kid goats showed a lower rate of ER and overall, a lower rate of ERf than lambs.

Two experiments were carried out to determine the nutritional value of a dehydrated cassava co-product (DCC) and its effects on the performance and blood variables of piglets fed with different levels of DCC. In experiment I, a digestibility assay was performed and 30 whole-male crossbred piglets with initial body weight of 18.00 ± 0.673 kg were housed individually in metabolism cages and distributed in a completely randomized experimental design with 5 treatments, 6 replicates and one animal per experimental unit. A reference diet was formulated to meet the category nutritional requirements and the different levels of DCC replacement (6, 12, 18 and 24%) were used to replace the reference diet and composed the treatments. In experiment II, 120 piglets (60 whole males and 60 females) were used, with initial body weight of 13.05 ± 1.59 kg, distributed in a randomized complete block design with 5 treatments, 6 replicates and 4 animals per experimental unit. Treatments consisted of five feeds with increasing inclusion levels (0, 3, 6, 9 and 12%) of the DCC. The feed based on corn and soybean meal were formulated to meet the recommended levels in starting piglets feeding. The data were submitted for statistical analysis and, when presenting significant difference, the averages were compared by the Dunnet’s test at 10 % significance. In the digestibility assay, the values of DCC’s digestive energy and metabolizable energy of 3,022 and 2,984 kcal kg -1 in natural matter, respectively, were found. There was no significant effect (p > 0.10) of inclusion levels of DCC on the final weight and daily gain of weight however we observed a quadratic effect (p < 0.10) of the DCC levels on daily feed intake and feed conversion. For the analysis of blood parameters, the results showed that there was no effect (p > 0.10) of DCC levels on glucose and blood urea in the different treatments. The use of the dehydrated cassava co-product can be an energetic alternative to piglets in starting phase and can be used up to 12 %.

This study evaluated levels of digestible lysine and organic zinc for male Ross strain broilers from 1 to 11 days of age. It was used 1,050 chicks distributed in randomized block design, in 5 × 2 factorial scheme, with seven repetitions of 15 birds per experimental unit. The dietary concentrations of digestible lysine were 0.90; 1.00; 1.10; 1.20; and 1.40% combined with 43 and 253 ppm zinc chelate. The diets contained 2,965 ± 18 kcal/kg of apparent metabolizable energy (AME) and 21.48 ± 0.18% of CP. It was determined chemical composition, protein, lipid, mineral and water depositions on carcass and empty body. There was no interaction among the factors digestible lysine and organic zinc. Effect of zinc concentration increase was observed on greatest deposition of body fat, indicating that there is interference in lipid metabolism of the birds in the studied phase. The most pronounced effects resulted from the dietary inclusion of lysine. There was a linear effect on reconstituted body weight as a response to the increase of dietary lysine, which suggests equal or superior requirement to the greatest studied level. However, the deposition of water and protein on the carcass had a quadratic increase, characterizing higher muscle mass accumulation up to the levels 1.25 and 1.27 of this amino acid in the diet. Considering the studied strain, broiler chickens from the first to the 11th days of age require 1.28 ± 0.01% of digestible lysine, according to the deposition of muscle mass.

Abstract This study aimed to evaluate, through life cycle assessment and using experimental data, the environmental impacts of growing pigs’ production (30 to 50 kg) fed diets with reduced crude protein (CP) levels, and supplemented with industrial amino acids. Experiment I (nitrogen and phosphorus balance): 20 crossbred barrows, averaging 31.80 ± 2.39 kg of initial body weight, were housed in metabolic cages and allotted in a randomized block design with four treatments, five replicates and one animal per experimental unit. Experiment II (performance): 44 crossbred barrows, averaging 30.10 ± 0.63 kg of initial body weight, were housed in a randomized block design, with four treatments, 11 replicates and one animal per experimental unit. The treatments for both experiments consisted of four diets containing 18.15, 17.15, 16.15 and 15.15% of CP, and supplemented with industrial amino acids, in order to meet the pig’s requirements of SID amino acids. According to the obtained data (Experiments I and II), the environmental impacts for global warming potential (GWP), acidification potential (AC), eutrophication potential (EU), cumulative energy demand (CED), terrestrial ecotoxicity (TE) and land occupation (LO), per kg of body weight gain, were calculated (CML 2001 method). There was a reduction in some studied environmental impacts as the dietary CP reduced from 18.15 to 15.15%, observing a reduction in the AC from 35.34 to 31.58 g SO2-eq (P = 0.015), there was also a reduction in the EU from 11.90 to 10.31 g PO4-eq (P = 0.001), and the LO was reduced from 2.15 to 1.89 m2-year (P = 0.005), respectively. GWP, CED and TE were not affected (P &gt; 0.05) by the dietary CP reduction, although some variations were observed. It was concluded that the dietary CP reduction, supplementing with industrial amino acids, may help to mitigate the environmental impacts caused by growing pig production for the AC, EU and LO categories.

Dietary Treatments

This study evaluated diets including whole or peeled (legs removed) crickets (Teleogryllus testaceus) in terms of diet digestibility, growth and nitrogen retention, using pigs as an animal model. The experiment included three iso-nitrogenous diets (18.4% crude protein) including either whole cricket meal (WC), body cricket meal (legs removed, BC) or fish meal (control) as the main protein source. Castrated male piglets (n=21, 30-45 days) with initial body weight 13.0±0.3 kg were allocated to one of the dietary treatments (7 piglets/treatment) in a fixed block design. The piglets were kept in single bamboo/wooden stalls with slatted floors and were adapted to the feeds and the housing for 5 days before starting the 25-day experiment. The diets were offered ad libitum, but close to appetite (approximately 5% of body weight). Feed intake was recorded and piglets were weighed every 5 days. During days 20-25, total collection of faeces and urine was performed. Dry matter and nutrient intake were higher for piglets fed the WC and BC diets than for those fed the control diet. From day 10, piglets fed BC and WC were heavier than piglets fed the control diet, but there were no differences between WC and BC. Dry matter digestibility was highest for diet WC, and ash, crude fibre and crude fat digestibility was higher for BC and WC than for the control diet. Feed conversion ratio was lower for the WC and BC diets than for the control diet, and nitrogen retention (% of digested) was higher. We concluded that field cricket meal is a nutritious feedstuff for mono-gastric animals, and most likely also for humans. Removal of legs did not facilitate or improve the digestibility values and nitrogen retention. Thus, in order to minimise food waste, crickets should not be peeled in this way if they are going to be processed into meal.
