“…High digestibility coefficients in passion fruit by-product were also observed by Lousada Jr. et al (2005) and Azevêdo et al (2011). Working with sheep fed silages containing increasing proportions of passion fruit by-product and elephant grass, Reis et al (2000) observed a linear decline in the digestibility of DM, CP, and NDF from the silages as the level of by-product in the mix was reduced.…”

Performance and digestibility of steers fed by-product of fresh passion fruit or sorghum silage, with and without concentrate supplementation

-The objective of this study was to evaluate the nutritive value of passion fruit by-product for cattle, contrasting the results with those found with sorghum silage. Four treatments were then constituted, comprising the combinations of the two roughages and the two levels of supplementation (with or without), in a completely randomized design with four animals per treatment. The considered variables included: feed intake, digestibility coefficients of the diets, and live weight gain of the animals. The experimental period lasted 70 days, preceded by a standardization period of 30 days. Chromium oxide was utilized to estimate the fecal output, in the digestibility trial. Treatments were compared by means of three orthogonal contrasts: between the two roughages and between the two concentrate levels within each roughage. Animals fed passion fruit by-product showed higher feed intake (total, per 100 kg of live weight (TLW), and per unit metabolic size) and had higher TLW gain than those fed sorghum silage (1.304 kg vs. 0.134 kg). The coefficients of apparent digestibility of dry matter (DM), organic matter (OM), and crude protein (CP) and the digestibility coefficient of neutral detergent fiber from passion fruit by-product were high, and much higher than those from sorghum silage. The concentrate supplement did not improve the TLW gain of animals fed passion fruit by-product and had a limiting effect on the digestibility coefficients of the diet. The concentrate supplement had a positive associative effect on intake and digestibility coefficients of DM, OM, and CP from sorghum silage. The by-product of fresh passion fruit is an excellent food for growing cattle as it provides high intake levels and weight gains, even when supplied as the only feed.

“…Alternatives to foods commonly used in intensive confinement systems have been researched, particularly due to the impact of this component on the cost of the system. In this context, agroindustrial residues have shown nutritional potential in the diet of ruminants, with satisfactory results on intake and animal performance (Azevêdo et al, 2011a(Azevêdo et al, , 2011b.…”

This study aimed to evaluate intake, digestibility, and performance in sheep fed increasing levels of annatto byproduct (AB). A total of 32 male sheep without defined breed were used. Their initial weight was 23.17±1.45 kg. The animals were housed in individual pens and offered feed twice a day. Nutrient intake was quantified by the difference between the fractions present in the offered feed and the remains. The apparent digestibility was estimated with the aid of the external marker LIPE ® . Weight gain was measured by the difference between the initial and final weight of the animals. The intake of dry matter (DM; g/day; g/kg BW; g/kg 0.75 ), organic matter (g/day), crude protein (CP; g/day), and neutral detergent fibre (g/day) was not affected (P>0.05) by addition of AB. The intake of ether extract (EE; g/day) and non-fibre carbohydrates (g/day) was influenced by the inclusion of AB. The apparent digestibility of DM, organic matter, CP, and EE was not affected (P>0.05) by the addition of AB. The AB can be included in the diet at levels up 300 g/kg of total DM without affecting consumption, digestibility, and weight gain in sheep.

The effect of pineapple by-product silage as a substitute for elephant grass on carcass yield, commercial cuts and non-carcass components was evaluated in 25 castrated male Santa Inês feedlot finishing lambs. The lambs had an initial body weight of 18.0±3.4 kg, and they were fed four pineapple by-product silage concentrations (0, 25, 50, 75 and 100%) distributed in a completely randomized design with five treatments and five repetitions. Lambs were slaughtered at a body weight of 30 kg. The hot carcass weight and hot carcass yield were recorded and chilled at 4°C for 24 h. The quantitative parameters of the carcass, the wholesale cuts expressed in kg and percentage, and non-carcass components were determined. Carcasses were divided into seven commercial cuts. The hot and cold carcass yields significantly increased when elephant grass was replaced with pineapple by-product silage in the diets. The weight of the false rib and loin cuts increased linearly when pineapple byproduct silage was added to the diets (P< 0.05). No significant differences were observed in the weights of the other cuts (P>0.05). The average weights of the non-carcass components were not affected by the addition of pineapple by-product silage, except for gastrointestinal tract (GIT) content, which decreased linearly, and omental-mesenteric, perirenal and internal fat depots, which increased linearly with the addition of pineapple by-product silage to the diets. The use of pineapple by-product silage as a substitute for elephant grass in growing lamb diets is recommended because it did not negatively affect the carcass characteristics, commercial cut yields or non-carcass components.
