Two experiments were conducted to determine the value of poultry offal meal (POM) as a protein supplement for layers and finisher broilers, respectively, at dietary levels of O, 10, 15 and 20%. In the layer experiment, body weights of layers increased with increasing dietary levels of POM. Treatments effects on feed intakes were not significant but egg production as well as feed efficiency were significantly (P < 0.05) improved by POM. In the broiler experiment, feed intake, growth rate, feed efficiency ad weights of livers were significantly (P < 0.05) higher at 15 and 20% POM dietary levels. Abdominal fat became significantly (P < 0.05) higher as from 10% POM dietary level. Poultry offal meal (POM), the processed edible and inedible parts of poultry (viscera, feathers, beaks, blood, discarded eggs and dead birds), used in this study contained (on dry matter basis) crude protein 56.4%, crude fat 20.9%, total ash 7.7%, crude fibre 4.6%, metabolizable energy 3.18kcal/gm.

1. Four varieties of marrow stem kale, three of thousand headed kales, Hungry Gap Kale and Rape-Kale were grown at three centres in mid-Wales. They were sampled in the early winter period and separate leaf and stem samples analysed for the proximate constituents and minerals.2. Leaf to stem ratios were measured on both a green and dry matter basis and the latter values used to calculate whole plant values for the chemical constituents.3. The leaves of the marrow stem kales were higher in dry matter than the stems, except in the case of the Purple Stem Kale. This variety resembled the thousand headed and rape-type kales in having a higher dry matter in the stems. On a dry matter basis, the leaves of all the varieties were richer than the stems in ether extract, crude protein, total ash and all the minerals except potassium and sodium. These elements occurred to a greater extent in the stems of the fleshy stemmed marrow stem kales than in the leaves. The stems were higher in crude fibre and nitrogen-free extractives.4. The leaves of the rape-type kales were higher than those of the other varieties in silica, phosphorus and potassium. They were the best source of phosphorus on a whole plant basis. The marrow stem kales had considerably higher leaf and stem values for sodium and were markedly superior to the other varieties as a source of the element.

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.

AbstractA study was conducted to compare the digestibility of organic matter (OM), neutral-detergent fibre (NDF), acid-detergent fibre (ADF), hemicellulose and nitrogen (N) and N balance in Mukota (M), Large White (LW) and the LW × M F1 pigs. Four male pigs of each breed, at proportionately 0·3 of their mature body weights, were randomly allocated to each of four diets in a cross-over design. The diets, which were formulated to contain similar levels of protein (ca. 160 g crude protein per kg) and energy (ca. 9 MJ metabolizable energy per kg), contained 0, 100, 200 and 300 g maize cob meal per kg, which corresponded to NDF levels of 276·4, 360·3, 402·9 and 523·5 g/kg dry matter, respectively. There was a negative correlation (P < 0·001) between the digestibility of OM, NDF, ADF and hemicellulose and the level of NDF in the diet. The digestibility of OM, NDF, ADF and hemicellulose decreased linearly (P < 0·05) with increase in the level of NDF among all three genotypes. There was a genotype × diet interaction on NDF and ADF digestibilities with digestibility in the LW decreasing faster (P < 0·05) than in the Mukota and LW × M F1 cross with increasing NDF. Both breed and level of maize cob meal affected N digestibility (P < 0·001), whilst the N retained per unit metabolic body weight was only affected by diet (P < 0·01). Increasing the level of maize cob meal beyond 100 g/kg, however, did not reduce N digestibility (P < 0·05). There was neither genotype nor dietary effect (P > 0·05) on N retained per unit N intake. These findings showed that the Mukota and the LW × M F1 cross were better able to digest the fibrous components than the LW. In addition, the Mukota and the LW × M F1 cross displayed an ability to retain protein to the same extent as the LW.

A 16-week feeding trial, involving 18 weaner pigs in a randomized complete block design, was carried out to determine the value of poultry offal meal (POM) as a protein supplement for grower pigs at three dietary levels, 0%, 10% and 20%. Liveweight gain, dressing percentage and backfat thickness were significantly (<0.05) higher in pigs fed 20% POM dietary level. The cut parts, heart, liver and kidney, also increased with increasing level of POM), the diets. The poultry offal meal (POM), the processed, edible and inedible parts of poultry (viscera feathers, beaks blood, discarded eggs and dead birds) used for this study, contained 56.4% crude protein 20.9% crude fat, 7.7% total ash 4.6% crude fibre and 3.18Kcal/gin metabolizable energy. The results of this study suggest that POM could be incorporated in grower pig rations up to 20% with good results.

The objective of this research was to evaluate the effect of sow age on apparent total tract digestibility of nutrients and the concentration of metabolizable energy in the diet. The experiment was carried out on 20 gestating sows, divided into two groups: Group I - 10 sows in first pregnancy (131 ± 4.5 kg) and Group II - 10 sows in fourth pregnancy (225 ± 8.2 kg). Sows in the two groups were fed identical diets for sows during early pregnancy. The total collection of faeces began on day 30 of pregnancy and lasted eight days. Sows in the fourth pregnancy had greater digestibility coefficients of dry matter (4.1 percentage units), organic matter (3.4 percentage units), crude protein (5.5 percentage units) and crude fibre (6.2 percentage units) than sows in the first pregnancy. The total tract digestibility of ether extract, starch and sugars was not affected by pig age. The metabolizable energy, determined according to the content of digestible nutrients, in the sow diet in fourth pregnancy was 0.7 MJ/kg higher than in the diet of sows in their first pregnancy. Results of this research indicate that sow age should be considered when formulating diets during early pregnancy.______________________________________________________________________________________Keywords: Digestibility, gestation, metabolizable energy, nutrients, age of sow

Abstract. The aim of the study was to determine the digestibility and energy content of Paulownia elongata S.Y.Hu leaves after leaf fall. Leaves together with petioles were dried at room temperature and milled with a roughage mill before feeding to animals. A classical digestion trial was performed, with three rams weighing 55.4kg on average, by determining the chemical composition of consumed feed, feed leftovers and excreted faeces. Digestibility was evaluated as difference in the amount of ingested nutrients and nutrients excreted with faeces and it was determined to be 50.72, 52.08, 31.63, 54.09, 55.15 and 56.06% for dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), crude fibre (CF) and nitrogen-free extract (NFE). The energy value for ruminants calculated on the basis of chemical composition and established digestibility was 8.29 MJ digestible energy (DE)/kg DM, 6.55 MJ metabolizable energy (ME)/ kg DM, 0.59 feed units for milk (FUM)/kg DM and 0.52 feed units for growth (FUG)/kg DM.

IN two separate experiments dried poultry waste (DPW) from caged-layer units was evaluated as a protein supplement for small ruminants. In experiment 1, nine goats divided into three groups of three animals each were randomly assigned to three diets containing 0,25, and 30% DPW in three periods of 17 days per period. Experiment 2 involved eight sheep, six of which were grazed and in addition fed in pairs to each of three diets containing 0, 20 and 30% DPW over a period of 12 weeks. The remaining two sheep were maintained solely on grazing during the same period of time.  Dry matter intake and digestibilities of dry matter, crude protein, crude fiber, other extract as well as liveweight gains and feed efficiency were not significantly different among the different treatments in experiment 1. Digestibility of nitrogen free extract was however significantly (P 0.05) different. In experiment 2, the control diet was consumed significantly (P 0.01) more than the diet containing 20% DPW. In general, intake decreased as DPW inclusion increased, but performance of animals on DPW supplemented remained as good or even better than those on the control diet. While supplementation produced on increase in liveweight gain of between 48-58% over initial bodyweight in 12 weeks, grazing alone promoted an overall in increase of 0.04% only during the same period.
