Valor nutritivo do resíduo da indústria processadora de abacaxi (Ananas comosus L.) em dietas para ovinos. 1. Consumo, digestibilidade aparente e balanços energético e nitrogenado

Abstract: O presente estudo foi conduzido para avaliar a influencia da inclusao do residuo do processamento de abacaxi (Ananas comosus L.) nas dietas sobre os consumos (por unidade de tamanho metabolico - UTM) e coeficientes de digestibilidade da materia seca (MS), materia orgânica (MO), proteina bruta (PB), extrato etereo (EE), fibra detergente neutro (FDN), fibra detergente acido (FDA), hemiceluloses (HCEL), celulose (CEL) e energia de dietas experimentais isofibrosas e isoproteicas. Avaliaram-se tambem os balancos nitrogenados e de energia dos animais. Vinte ovinos machos, inteiros receberam racoes com quatro niveis de inclusao do residuo (0; 11%; 16%; 27%) em base de materia seca, em delineamento inteiramente ao acaso, com cinco repeticoes por tratamento. Maiores consumos de materia seca foram evidenciados quando as racoes continham 11% do residuo. Maiores consumos de proteina bruta, fibra detergente neutro, fibra detergente acido e celulose (g/UTM) e energia metabolizavel (kcal/UTM) foram apresentados por animais alimentados com dietas contendo 11% de residuo em relacao ao das dietas com 27% de inclusao (P<0,05). Maior coeficiente de digestibilidade da FDA ocorreu para dietas que nao continham o residuo de abacaxi. Os coeficientes de digestibilidade da CEL foram semelhantes. Os balancos energeticos e proteicos foram positivos. Melhores resultados para os parâmetros analisados foram observados para dietas que incluiam ate 16% do residuo de abacaxi na base da materia seca.

Comportamento de ovinos em capim-tanzânia sob lotação rotativa com quatro níveis de suplementação concentrada

Abstract: The sheep behavior over 24 hours in Tanzania grass irrigated pastures under four supplementation levels (0.0; 0.6; 1.2 and 1.8% LW) was evaluated in this work. A complete randomized design with six replicates (sheep) was used. The percentage of total time under shade, grazing, ruminating, in "other activities", in idleness, the number of supplement/salt ingestions, defecations, urinations, water ingestion and bite rate were estimated, splitting the day in eight periods of three hours (from 5 to 8 a.m.; 8 to 11 a.m.; 11 a.m to 2 p.m; 2 to 5 p.m.; 5 to 8 p.m.; 8 to 11 p.m.; 11 p.m. to 2 a.m.; 2 to 5 a.m). The highest grazing time occurred in animals without supplementation and decreased gradually and increased back again in the supplementation level of 1.8% LW. The rumination time was higher in the supplementation level of 0.6% LW, mainly in the periods from 2 a.m. to 5 p.m and from 5 p.m to 8 p.m. The idleness time was higher in the supplementation level of 1.2% LW. Water ingestion increased up to time the supplementation level of 1.2% LW and was concentrated in the period from 11 a.m to 2 p.m. The urination and defecation frequency was higher in the supplementation level of 1.8% LW. The gradual increase of bite rate up to the supplementation level of 1.2% LW, in the periods from 11 p.m to 8 p.m, with posterior decrease, suggests an additive effect of the supplement on the grass until such level, and a substitutive effect beyond this level. The total time under shade was concentrated in the periods from 8 a.m. to 2 p.m and decreased with the supplementation level up to 1.2% LW. The supplementation level affected the sheep behavior under grazing, where the supplementation level of 1.2% LW presented optimization of the ingestive capacity of the grazing sheep. The highest supplementation levels compromised the ingestive behavior, suggesting that changes on ration formulation in such levels should be implemented.

Desempenho produtivo e características de carcaça de ovinos em confinamento alimentados com rações contendo torta de mamona destoxificada em substituição ao farelo de soja.

Abstract: The objective of this study was to evaluate the influence of four substitution levels (0; 33; 67 and 100%) of soybean meal by detoxified castor cake on performance and carcass characteristics of 20 non-castrated male crossbred Morada Nova lambs, with mean body weight of 18.7 kg, in a randomized blocks design with four treatments and five replicates. Performance, carcass weight, carcass yield and relative composition of the commercial cuts were evaluated. The substitution levels of soybean meal by detoxified castor cake had no effect on final live weight or total weight gain in feedlot, but it caused decreasing linear effect on average daily gain and feed conversion ratio was observed. There was no effect of the substitution levels of soybean meal by detoxified castor cake on final body weight, live weight at fasting, empty body weight, hot carcass weight or cold carcass weight. The hot carcass yield was affected by substitution levels; the same behavior was observed for cold carcass yield. Rib weight and yield and shoulders yield had linear decrease of substitution levels of soybean meal by detoxified castor cake, whereas weight and yield of other regions did not present any effect for the substitution levels. Detoxified castor cake can be utilized in levels of up to 67% in substitution of the soybean meal in sheep diets.

Resíduo agroindustrial da carnaúba como fonte de volumoso para a terminação de ovinos

Abstract: The objective of this work was to evaluate the effects of ammonization with different levels of urea and the use of soybean grains as a urease source, for the improving of the chemical composition of carnauba (Copernicia prunifera) agroindustrial residue (BC) The levels of urea were 0, 25, 5, 75 and 10% in relation to the percentage of total dry matter of BC and the levels of toasted soybean grains were 0 and 20% Evaluations were also made for forage intake and performance of confined sheep subjected to diets with increasing levels of replacement of Tifton 85 grass (Cynodon spp) hay (FT) by BC: 100% FT, 25% BC plus 75% FT, 50% BC plus 50% FT, 75% BC plus 25% FT, and 100% BC Thirty crossbred 80-day old weaned sheep with 17 kg initial average weight were used Crude protein in the forage increased with the increasing doses of urea Increases were also observed for neutral detergent fiber and cellulose contents and reductions were observed for roughage digestibility The highest daily intake of dry matter, organic matter, crude protein, ethereal extract and neutral detergent fiber were observed in animals fed only FT Animal performance decreased with increase of BC in the diet

Developing novel anthelmintics from plant cysteine proteinases

Abstract: Intestinal helminth infections of livestock and humans are predominantly controlled by treatment with three classes of synthetic drugs, but some livestock nematodes have now developed resistance to all three classes and there are signs that human hookworms are becoming less responsive to the two classes (benzimidazoles and the nicotinic acetylcholine agonists) that are licensed for treatment of humans. New anthelmintics are urgently needed, and whilst development of new synthetic drugs is ongoing, it is slow and there are no signs yet that novel compounds operating through different modes of action, will be available on the market in the current decade. The development of naturally-occurring compounds as medicines for human use and for treatment of animals is fraught with problems. In this paper we review the current status of cysteine proteinases from fruits and protective plant latices as novel anthelmintics, we consider some of the problems inherent in taking laboratory findings and those derived from folk-medicine to the market and we suggest that there is a wealth of new compounds still to be discovered that could be harvested to benefit humans and livestock.
