“…Based on the published result, the total production area of the Iranian potato sector is estimated at 160,000 -170,000 hectares. Total annual production of about 5 to 5.5 million tons [2]. The potato processing industry in Iran is growing, and about 13% of the total volume of potatoes production is processed (about 700,000 to 800,000 tons per year).…”

“…The potato processing industry in Iran is growing, and about 13% of the total volume of potatoes production is processed (about 700,000 to 800,000 tons per year). French fries and chips are the most important segments in the processing industry [2]. In addition to this, potatoes are processed for flakes, mash potatoes and salads as well.…”

In this way, for each incubation time (2,4,6,12,24,36, and 48 h), 4 vials (replicates) were allocated to each of the experimental treatments, and 4 vials were assigned to the blank as well. Each run contains 224 vials (including 7 experimental treatments plus blank, 7 incubation times, and 4 replications).…”

Background: The increasing urban population requires more dairy product (meat and milk) production; therefore, using agricultural sector by-products as animal feedstuffs has found double importance. Objective: The effects of replacing barley grain with heated potato slices (HPS) and French fries waste (FFW) in iso-energetic total mixed dairy cow rations on cumulative gas production and in vitro DM degradability were evaluated using in vitro techniques. Methods: Seven experimental dairy cow total mixed rations (TMR) were formulated based on partial replacing barley grain with HPS or FFW, including Control: a diet containing 16% (DM basis) barley grain as one of the main sources of non-forage carbohydrates; 5 HPS: a diet containing 11% barley grain and 5% HPS; 10 HPS: a diet containing 6% barley grain and 10% HPS; 15 HPS: a diet containing 1% barley grain and 15% HPS; 5 FFW: a diet containing 11% barley grain and 5% FFW; 10 FFW: a diet containing 6% barley grain and 10% FFW; 15 FFW: a diet containing 1% barley grain and 15% FFW. Two in vitro gas production approaches were conducted separately to measure the production of gas volumes and dry matter (DM) degradability at 2, 4, 6, 12, 24, 36, and 48 hours of incubation. Results: After 48 h of incubation, the gas production volume varied between 174 and 197 ml/g DM, with the highest value observed with control and the lowest value with FFW treatments (P < 0.05). Also, the gas production rate for the insoluble fraction varied from 0.031 to 0.054 ml/h and was higher for HPS treatments than for control and FFW treatments (P < 0.05). After 48 h of incubation, DM degradability was significantly lower for the control than other treatments. DM effective degradability, with a passage rate of 0.05 h−1, found to be higher for FFW and HPS treatments compared with the control. Moreover, the rate of the B fraction degradation was significantly lower for the control (0.14 % h−1) than for treatments. Conclusion: The heated potato processing by-products could be replaced with barley grain by 15% in the diet of dairy cows without having negative effects on ruminal fermentation.
