This aim of this study was to evaluate the intake and apparent digestibility of nutrients, ingestive behavior, blood parameters, and performance of lambs fed two roughage:concentrate (R:C) ratios, with or without liquid residue of cassava (LRC). Forty lambs (19.5?±?1.45 kg body weight) were distributed in a completely randomized 2?×?2 factorial design. The intake of dry matter (1311 g/day) and total digestible nutrients (755 g/day), and the intake (172 g/day) and digestibility (552 g/kg) of crude protein were higher for lambs fed R:C of 40:60. The R:C ratio of 80:20 promoted a higher intake (585 g/day) and digestibility (461 g/kg) of neutral detergent fiber. There was an intake of LRC of 1.37 L/day for lambs fed R:C of 80:20 and 0.42 L/day for lambs fed R:C of 40:60. The lambs fed R:C of 80:20 spent more time in feeding (326 m/day) and rumination (530 m/day). The metabolic profile and performance of lambs were not affected by LRC inclusion. The body weight gain (220 g/day) was higher in lambs fed R:C of 40:60. A roughage:concentrate ratio of 40:60 is recommended for lambs because it resulted in the best performance, regardless of supplementation with liquid residue of cassava. 相似文献

Five lactating goats were used in a 5 x 5 Latin square experiment to determine the effects of feeding whole sugarcane (WSC)
on intake, total tract nutrient digestibilities, milk yield and milk composition. Goats were fed diets containing 0, 100,
200, 300, and 400 g kg-1 WSC and 400, 300, 200, 100, and 0 g kg-1 tifton hay (TH). Intake of dry matter and neutral detergent
fiber (NDF) decreased linearly (p < 0.05) as the level of WSC in the diet increased. Total tract nutrient digestibilities
were not influenced by WSC inclusion except for the digestibility of NDF which decreased linearly (p < 0.05) as the level
of WSC in the diet increased. Inclusion of WSC linearly (p < 0.05) decreased milk yield without affecting milk composition.
It was concluded that WSC had a lower feeding values than TH for lactating goats. 相似文献

The objective of this experiment was to determine the effects of replacing corn with soybean hulls (SH) or Bermudagrass tifton
hay (TH) on performance of sheep fed cactus-based diets. Three ruminally fistulated sheep were used in a 3 × 3 Latin square
experiment with 21-day periods. All diets contained 75% spineless cactus (dry matter basis, DM) and formulated to be isonitrogenous.
Fiber source had no influence on nutrient intakes except for the intake of neutral detergent fiber (NDF) which was lower (p < 0.05) for animals fed corn relative to those fed SH or TH. Time expended in rumination and total chewing time were higher
(p < 0.05) for animals fed TH than those fed SH or corn. In vivo nutrient digestibilities were similar for all dietary treatments
and averaged 69.6%, 74.8%, 69.9%, and 61.8% for DM, organic matter, crude protein, and NDF, respectively. Feeding SH relative
to TH and corn decreased ruminal pH (p < 0.05) and increased concentration of total volatile fatty acids (p < 0.05). However, ruminal NH3–N concentration was higher (p < 0.05) for animal fed TH than for those fed SH or corn. Abdominal distension and ruminal biofilm production were greater
(p < 0.05) in animals fed corn or SH than in those fed TH. It was concluded that replacing corn with SH or TH up to 15% of the
diet DM in a cactus-based diet had no effect on nutrient intakes or total tract nutrient utilization. Changes in ruminal fermentation
parameters reflected differences in ruminal degradability between the two fiber sources. Bermudagrass tifton hay was more
effective than SH in reducing the risk of bloat associated with feeding high levels of spineless cactus to ruminants. 相似文献
