| Abstract |
The experiment objective was to assess the shifting efect from cassava chip (CC) to fresh cassava
root (FC) afected feed utilization, rumen metabolism, cyanide-using bacteria, and milk quality in
lactating Thai Friesian dairy cows fed diets based on high sulfur-containing pellet (PS). Four lactating
Thai Friesian dairy cows of 481.5 ± 31.3 kg BW (about 4 years old were allocated with four treatments
in a 4 × 4 Latin square design. The four treatments were: replacement FC for CC at 0%, 60%, 80%, and
100% dry matter (DM), respectively. Feed intakes for four diets in terms of total dry matter intake
(kg/day and % BW) was linearly correlated with levels of replacement of FC (p< 0.01). Digestibilities
of crude protein (CP), DM, organic matter (OM), amylase-treated neutral detergent fber (aNDF),
and acid detergent fber (ADF) did not change with increasing levels of FC in the diet (p> 0.05).
Moreover, the total bacterial counts and cyanide population utilizing bacteria cubically increased
with an increase of FC replacement (p< 0.01). The efect of CC substitution with FC in the PS diet was
cubically increased on blood thiocyanate concentrations (p< 0.01). In addition, the propionate (C3)
concentration at 0 and 4 h post-feeding changed signifcantly among treatments (p< 0.01), which were
linearly improved with an increasing dose of replacement FC and were highest when FC was replaced
at 100%. The yield of 3.5% fat-corrected milk was high in the treatment with the replacement of FC as
compared to the control (p< 0.01). The yield of fat and milk fat percentages was high (p< 0.01) in the
group with the replacement of FC as compared to feed with no diet replaced. The milk thiocyanate
concentration was cubically enhanced when levels of FC replacement increased (p< 0.01) and was the
highest when FC was replaced at 100%. As the amount of FC replacement was raised, the somatic cell
count in the milk decreased linearly (p< 0.01). In conclusion, the replacement of FC at 100% in PS could
enhance the feed intake, microbial populations, total volatile fatty acid (VFA), C3 concentration, milk
yield, and milk quality. |
