“…The chemical composition of forage used in the study is presented in Table 1. The AH and IRH used in the study (Table 1) had a high DM content that is usual when ensiling forage into bales wrapped with plastic (Vranic et al, 2018). Corn grain had a high starch content and dried whey had a high lactose content (Table 1).…”

“…The higher digestibility of DM, OM, NDF and higher D-value of a low intake of forage-based dietary treatments can be accounted for by the longer presence of forage high in fiber and low in CP in the digestive tract of ruminants. The intake of low-quality forage will be limited by the rumen's physical fill (Allen, 2000), and the intake of high-quality forage by the energy consumed (Vranic et al, 2018). The high-quality forage with a high DMI will linger in the digestive tract of ruminants for one to two days and that of low quality and low DMI for more than three days (Sayan et al, 2010).…”

“…For the foregoing reasons, high-energy supplements to forage will have a variable effect on the nutritional value and energy efficiency of diet for ruminants. It depends on the type and quantity of supplement (Chamberlain et al, 1993) as well as the main forage (Orr et al, 2001;Vranic et al, 2007;Salcedo et al, 2010;Vranic et al, 2013;Vranic et al, 2018) that can have a higher impact on intake and digestibility than the high-energy supplement itself (Waldo, 1986). The aim of our study is to establish the effects of partial replacement of corn grain with dried whey on ad libitum feed intake, in vivo digestibility and N The present study hypothesized that (i) replacing corn grain with dried whey would increase the intake, digestibility and N retention of feed based on alfalfa haylage (AH) or on Italian ryegrass haylage (IRH), and that (ii) an AH-based diet would have higher intake, digestibility and N retention compared to IRH-based diet.…”

An in vivo study was conducted into the effects of partial replacement of dried ground corn grain with dried whey -as a supplement to alfalfa haylage (AH) or Italian ryegrass haylage (IRH) -on ad libitum intake, in vivo digestibility and N retention in wether sheep. The chemical composition of AH and IRH was roughly the same, except for the crude protein (CP) content which was much higher in AH compared with IRH. Sheep fed the AH-based diet had higher feed intake. Higher CP digestibility and higher N retention, as well as higher levels of excreted N, were shown compared IRHbased diet. The IRH-based diet increased the digestibility of chemical parameters studied, except CP and starch. The partial replacement of corn grain with dried whey reduced the intake of acid detergent fibre (ADF), improved the starch digestibility in AH and IRH-based diets, and increased the overall N intake in wethers fed the AH-based diet. In practical conditions, replacing 10% of corn grain with dried whey in a ration based on higher quality forage is a way to increase N intake in sheep. In conclusion, the partial replacement of corn grain with dried whey in a forage-based diet with higher CP content improves the nitrogen efficiency in the diet of wether sheep.

“…Alfalfa is a leguminous crop that has abundant crude protein, vitamins, and amino acids (Wang et al 2003). It is a favorite forage for livestock (Wang et al 2017;Vranic et al 2018;Zhao et al 2019). Due to the low bulk density of alfalfa, it takes up a lot of space during storage and transportation.…”

Compression alfalfa into briquettes is an effective way to solve the problem of storage and transportation. In the process of compression, heat is generated, which raises the temperature in the material. The appropriate temperature can improve the quality of alfalfa briquettes. In this paper, the effect of assisted vibration frequency, moisture content, and particle size on the compression temperature were tested. The results showed that when the vibration was applied, the material particle temperature in the mold rose significantly, and the core particle temperature rose faster than the edge temperature. The vibration frequency was the most significant factor affecting heat transfer in the three studied factors. When the moisture content and particle size were constant, the heat transfer effect increased first and then decreased with the vibration frequency, and it had an optimal value at 17 Hz. When the vibration frequency and particle size were constant, the heat transfer effect increased first and then decreased with the moisture content. It had an optimal value of 20%. The experimental results explained the effect of vibration frequency, moisture content, and particle size on temperature variation during alfalfa compression and provided a basis for reasonable process parameters.
