“…According to the authors, this is due to lower dry matter intake of treatment with 10% hay, since the animals usually consume food to meet their energy requirement. Parente et al (2009) 0.20 kg. Considering the forage: concentrate ratio of 42.75: 57.25, this result is higher than those observed herein, probably the explanation is related to higher proportion of concentrate used in the diet.…”

This study aimed to evaluate the performance of feedlot lambs fed diets formulated with hay of different genotypes of Cynodon spp. and to compare the dry matter digestibility of diets using different evaluation methods (total fecal collection and chromium oxide). Suffolk crossbred neutered male lambs (n=30), with an average age of 90 days and average body weight of 21.5 kg ± 1.6. Diets were formulated using a standard concentrate and hay of the following genotypes of Cynodon dactylon: Jiggs, Vaquero, Tifton 68, Coast-Cross, Tifton 85 and Russell, in a 60:40 forage concentrate ratio, composing the treatments distributed in a randomized block design in a factorial 5 x 2 arrangement of 5 diets and 2 digestibility evaluation methods. Animals receiving Vaquero hay showed dry matter intake of 18.3; 16.9; 25.6; 20.7 and 24.2% higher than those fed hay of Jiggs, Tifton 68, Coast Cross, Tifton 85 and Russell, respectively. There was no difference between diets for digestibility using total fecal collection, chromium oxide and final weight of animals. Jiggs hay based diets allowed greater daily weight gain and better feed conversion.

“…O desempenho produtivo de ovinos em sistema de confinamento foi avaliado por Parente et al (2009), com diferentes dietas, sendo uma delas a base de 19 % de inclusão do resíduo de maracujá. O consumo de matéria seca (MS) foi elevado para todas as dietas, obtendo-se uma média de 1458,10g animal -1 dia -1 , já para o ganho médio diário de peso (217,20 g) se destacou em relação às demais.…”

Uso de coprodutos de frutas tropicais na alimentação de ovinos no Semiárido do Brasil

Os resíduos agroindustriais, coprodutos, podem servir para amenizar a falta de alimento para ovinos na região Nordeste e somam mais de 290 milhões de toneladas, representando perda de biomassa e de nutrientes, além de ser potencialmente poluidor de solos e corpos hídricos. O Brasil é o terceiro maior país produtor de frutas do mundo e o primeiro na produção de frutas tropicais, com 47 % das frutas consumidas in natura e 57 % processadas, cujo resíduo pode chegar a 50 % da biomassa original. A região Nordeste apresenta condições favoráveis para a fruticultura, possuindo mais de 30 pólos de produção que juntos produziram 11 297 984 toneladas de frutas, o que corresponde a mais de 55 % da produção das principais frutas tropicais do território brasileiro, com potencial de geração de 5 787 884 toneladas de coprodutos. As frutas estudadas foram o abacaxi, melão, caju, goiaba, mamão e maracujá que, de maneira geral representam fontes alimentares para os ovinos, apesar de terem restrições em proporção da dieta e que são diferentes para cada fruta. O processo de agroindustrialização de frutas no Brasil, devido aos mercados mais exigentes, tende a gerar coprodutos com menos variação na sua composição química, o que é benéfico ao setor pecuário devido à qualidade do coproduto gerado.

“…It is expected that, due to existing commonalities, the information emerging from this study regarding the characteristics and major constraints to Awassi lamb fattening systems could be useful for other tropical and subtropical dry areas where a large demand for small ruminant meat provides income generation opportunities thorough fattening systems for resource-poor farmers, i.e., in Mexico (Pinos-Rodríguez et al, 2007;Zamudio et al 2009) and Brazil (Parente et al 2009). …”

Intensive lamb fattening systems are evolving in developing Middle Eastern countries due to high demand for lambs at favorable prices; however, little is known about their characteristics and constraints. A survey was conducted in Syria involving 241 farmers to characterize the fattening production systems and main constraints, with emphasis on feeding, management, labor, and marketing. Most farmers (90%) considered the income from fattening to be from medium to high, and 57% expressed that lamb fattening along with alternative income sources compose the family's livelihood strategies. Fattening systems offer employment to family members. Market price was the main decision factor to buy and sell lambs, but this was only part of various marketing aspects. Male lambs usually bought at markets at the mean age of 4 months (mean weight of 31 kg) are sold after fattening at a 50-60 kg weight range. The average yearly fattening cycle was 2.7 batches, and the average number of lambs per batch was 232. For 65% (n = 241) of the farmers the major constraint to fattening was feeding cost, and for about a half of farmers (51%, n = 241), disease outbreaks and prices for veterinarian services constituted the second important constraint. Research on least-cost fattening diets and curbing disease problems to increase farmer's income margins is needed. It is expected that due to existing commonalities, the information emerging from this study regarding major constraints to Awassi lamb fattening systems could be useful for an across-synthesis on Awassi fattening production in the region.
