“…Forage quality parameters of both types of silage used in the dairy cow experiment described in [1] were close to the phenological stages, digestibility and the CP content of the yields of the two-cut and one of the three-cut systems at Løken Research Station used in Flaten et al. [4] .…”

“… [4] . Therefore, we considered it to be appropriate to use these two- and three-cut systems too estimate the costs of feeding dairy cows with low crude protein silage and optimal crude protein silage in study [1] , respectively. The two-cut system in [4] were represented by harvesting regime 8 ( Table 1 ), whereas the three-cut system was composed of a 50:50 mixture of harvesting regime 4 and harvesting regime 7.…”

“…Based on these calculations, the total cost of producing silage were NOK 1.84 per kg DM for the two-cut system and NOK 2.29 per kg DM for the three-cut system ( Table 3 ), and in [1] these estimates are used to represent the cost of low crude protein silage and optimal crude protein silage, respectively.…”

This article presents input data and procedures used to estimate costs of producing grass-clover silages under Norwegian farming conditions. Data of yield, botanical composition and forage quality of the grass crop were derived from a field experiment comparing a three-cut system, harvested at early crop maturity stages producing highly digestible forages, and a two-cut system returning higher herbage yields of medium digestibility. Secondary data on prices of specific inputs were also provided. The data presented here can be used by advisors and farmers as a decision support tool for assessing and comparing costs of different ways of producing silage. Cost estimates of home-grown forages are also needed in bio-economic evaluations of grassland production and utilization by researchers. The data presented is related to the research article entitled: “Technical and economic performance of alternative feeds in dairy and pig production” [1] .

“…Processing costs and energy sources are a concern in the production of alternative ingredients [ 5 ]. An increased cost to produce animal protein reflects the ineffective use of nutrients and excretion, e.g., of nitrogen, to the environment, as well as an increase in carbon emission [ 26 ]. The introduction of vegetable leftovers in pig feed is unavoidable due to upcoming food-feed competition.…”

The objective of this study was to determine the effect of bitter gourd (BG) leftovers (stems and leaves) as an alternative dietary ingredient on pig performance, carcass characteristics, serum parameters (urea, insulin, and leptin levels), and faecal consistency. Healthy Tempo × Great Yorkshire and Landrace pigs (N = 240; 120 gilts and 120 boars) weighing 25.8 kg (9–10 weeks of age) were randomly assigned to three treatments (eight pens per treatment; each pen with five gilts and five boars). The three treatments consisted of a non-supplemented commercial diet (control; CON) and a CON diet supplemented with 6.5 g/kg BG (BG1) or 13 g/kg BG (BG2). Pigs were fed the experimental diets until slaughter (120 kg body weight; BW). Feed intake was recorded daily and calculated for each experimental phase (i.e., days 0–36, days 36–66, days 66–98, and the overall experimental period). Average daily feed intake (ADFI), average daily gain (ADG), and feed conversion ratio (FCR) were calculated. The frequencies of visiting the feed station and of feeding were recorded daily. Faecal scores (FS) for consistency were measured per pen twice weekly. On the day of slaughter, two pigs per pen (one male and one female) were randomly selected for the measurement of muscle thickness and blood collection. At the slaughterhouse, carcass weight, dressing percentage, back fat thickness, muscle depth, and lean meat percentage were recorded. Data were analysed using ANOVA, with the pen as the experimental unit. Diets BG1 or BG2 did not affect the performance of the pigs, except for a significant decrease in the ADG of the pigs fed the BG2 diet in the feeding period of 50–80 kg. However, no differences in performance were observed in the overall experimental period. Faecal scores, carcass quality, and serum levels of urea, insulin, and leptin were also not affected by the diet. In summary, leftovers (stems and leaves) of BG can be successfully added to the diet of growing-finishing pigs without interfering with performance and carcass characteristics.
