“…periods of scarcity, obtaining an alternative food for the animals becomes of great importance for the intensive farming system, reducing feed costs. Current studies and work on the use of pineapple crop residues have shown very promising results with the use of silage as a form of forage storage and with good results from its use in feeding ruminants (Fagundes & Fagundes, 2010;Lallo et al, 2003;Prado et al, 2003;S. C. Santos et al, 2014), as well to minimize environmental contamination with the large amount of vegetable waste produced (M. Santos, 2010).…”

“…Brazil occupies a prominent position in pineapple growing as the third largest world producer, with almost 1.5 billion fruits harvested from approximately 64,147 ha of cultivated area (Instituto Brasileira de Geografia e Estatística [IBGE], 2022). The industrialization of tropical fruit farming has provided enormous surpluses of byproducts, which in the natural or processed form could contribute a significant portion to ruminant nutrition (Cunha et al, 2009;S. C. Santos et al, 2014).…”

The use of crop residue silages is a viable alternative for producers to reduce feed costs. The present study was developed with the objective of investigating the inclusion of pineapple silage in replacement of sorghum silage in the diet of lactating cows regarding feed intake, production, and quality of milk. Eight crossbred (Holstein × Gir) cows with an average weight of 555±30 kg and an average milk yield of 12.50±3.25 kg/day, between 60 and 90 days in milk, were distributed into two simultaneous 4 × 4 Latin squares, at one animal per experimental unit. Silage of pineapple crop residue (PS) using plants after the harvest of the fruits was included in the roughage portion of the diet at increasing levels, with simultaneous and proportional removal of sorghum silage (SS) from the diets. The studied treatments thus consisted of the roughage portion containing: 1- 0% PS and 100% SS (100SS); 2- 34% PS and 66% SS (34PS66SS); 3- 67% PS and 33% SS (67PS33SS); 4- 100% PS and 0% SS (100PS). The diets were supplied twice daily, allowing 5% leftovers in relation to the quantity offered. The amounts of feed supplied, and orts of each animal were weighed for a subsequent determination of intake. The experiment was divided into four 21-day sub-periods, the first 14 days of which were used as an adaptation to the diet, while the others served for data collection. The milk was weighed from the 15th to the 19th day of each experimental period, and milk samples were collected on the last day of each period. Milk samples were sent to the laboratory, where they were analyzed. Dry matter, mineral matter, and lignin concentrations in the diet did not vary (P>0.05) as a function of PS inclusion in the roughage portion, while protein content, fiber content, and fat content levels were influenced. No effect of PS inclusion was observed (P>0.05) on the intakes of dry matter, neutral detergent fiber, mineral material, or lignin. However, PS inclusion prompted (P<0.05) a linear increase in the intakes of protein and total fat. The inclusion of pineapple plant silage in the roughage part of the diet had a positive effect (P<0.05) on milk yield, 4% fat-corrected milk yield, and on the milk fat and total solids contents. Milk production, as well as fat and total solids content, increased moderately with inclusion of pineapple plant silages in the roughage portion of the diet. Therefore, pineapple silage can replace sorghum silage in the roughage part of diets for lactating crossbred cows.

“…The expansion of fruit farming combined with investments in agroindustries results in increased amounts of byproducts, which may increase operating costs for companies and potentially become an environmental problem depending on how the byproducts are discarded (Santos et al, 2014). Brazil is among the largest pineapple-producing countries (Ananas comosus (L.) Merril) in the world, contributing 9.89% of global production (CONAB, 2020).…”

“…Although few studies have been carried out using pineapple crop waste in ruminant feeding, they have shown very promising results, apparent digestibility of dry matter (DM) of 665.80 g/kg, and digestibility of neutral detergent fiber of 548.6 g/kg (Santos et al, 2014). Thus, we hypothesized that pineapple crop waste can be used as a roughage source in sheep feeding in times of feed scarcity.…”

The study aimed to nutritionally evaluate the silage of pineapple crop waste in sheep feeding in different planes of nutrition (L). We used eight growing sheep and four male castrated adults, in individual metabolic cages distributed in a switchback design with two treatments and three periods. The treatments were the different planes of nutrition: L = MEI⁄M m , MEI⁄1.5M m , and MEI⁄2.5M m , in which L = MEI/M m , MEI is the energy amount of the feed intake and M m is the maintenance. We performed a digestibility trial of the diet composed of silage of pineapple crop waste, ground corn, and soybean meal. Data were analyzed using regression analysis. Nutrient intake behaved linearly according to the increase in the L, except for organic matter, which presented a quadratic behavior. Planes of nutrition did not affect protein and fiber digestible fractions. However, digestible fractions of fat and non-fibrous carbohydrates (NFC) increased with L. The indigestible fractions displayed a quadratic behavior with an increase in the L. Regarding the microbial synthesis efficiency, we observed a linear decrease with the increase in L. Thus, the silage of pineapple crop waste is a feed very rich in NFC. Besides, silage of pineapple crop waste presented a good alternative roughage during forage shortages. Diet inclusion of 2.5x the maintenance does not compromise the sheep performance.

“…A industrialização da fruticultura tropical tem propiciado importantes quantidades de resíduos ou de subprodutos, que in natura ou beneficiados, possuem potencial de contribuir de forma expressiva na alimentação de ruminantes (Santos et al, 2014), consequentemente, se faz necessário avaliar esses substratos no intuito de se determinar níveis de inclusão adequados, baseando-se nos aspectos nutricionais, digestivos, comportamentais e na viabilidade econômica destas diferentes alternativas.…”

Objetivou-se avaliar os níveis de sementes de cupuaçu em substituição ao grão de milho (0; 25; 50; 75 e 100%) na alimentação de ovinos, sobre o desempenho e digestibilidade das dietas. Os 20 ovinos machos, idade de 10±1 meses, receberam, durante 56 dias, dietas compostas por feno de tifton, farelo de soja, ureia, minerais e grão de milho (60% da matéria seca da dieta) sendo substituídos por sementes de cupuaçu, conforme os níveis. Os animais foram confinados em baias individuais e receberam a dieta a vontade, duas vezes ao dia, preconizando 10% de sobras. O delineamento foi inteiramente casualizado e os dados submetidos à análise de variância, contrastes polinomiais e análise de regressão, ao nível de 5%. O consumo de matéria seca, consumo de proteína bruta, ganho de peso, peso final e digestibilidade da matéria seca reduziram linearmente com o aumento da substituição do grão de milho pela semente de cupuaçu. O consumo de extrato etéreo aumentou linearmente com a substituição do grão de milho pela semente de cupuaçu. O valor da conversão alimentar aumentou com a inclusão da semente de cupuaçu. As digestibilidade do extrato etéreo e da fibra detergente neutro apresentaram efeitos quadráticos. A substituição do milho pela semente de cupuaçu influencia no desempenho de ovinos confinados e na digestibilidade das dietas, mas não comprometeu a terminação dos animais visando o peso de abate.
