“…There is only a small amount of okara, which is sometimes used for feeding purposes [ 90 ]. For example, in the United States, part of the okara, which comes from the production of organically certified soy milk and tofu, is used for feeding purposes in organic herds [ 99 ]. Due to differences in sources and processing methods, the nutritional value of okara is very variable.…”

“…Research focused on the use of dried okara (i.e., okara meal) as a protein source in lactating dairy cows is lacking. Recent results have proved that okara meal is a suitable replacement for soybean meal in dairy diets, without negative effects on lactation performance and dry matter intake [ 99 ].…”

“…Camelina seeds are also relatively abundant in essential amino acids [ 114 ], highlighting the potential of camelina as a high-quality feed for ruminants. Several studies have shown that the usage of camelina seeds, cakes, or oil can alter the milk fat composition in cows fed with diets based on maize silage [ 99 ], red clover silage [ 119 ], or grass silage [ 116 , 120 ]. Similar effects were also observed in goats and sheep [ 121 , 122 , 123 ].…”

Milk fat is an important nutritional compound in the human diet. From the health point of view, some fatty acids (FAs), particularly long-chain PUFAs such as EPA and DHA, have been at the forefront of interest due to their antibacterial, antiviral, anti-inflammatory, and anti-tumor properties, which play a positive role in the prevention of cardiovascular diseases (CVD), as well as linoleic and γ-linolenic acids, which play an important role in CVD treatment as essential components of phospholipids in the mitochondria of cell membranes. Thus, the modification of the FA profile—especially an increase in the concentration of polyunsaturated FAs and n-3 FAs in bovine milk fat—is desirable. The most effective way to achieve this goal is via dietary manipulations. The effects of various strategies in dairy nutrition have been thoroughly investigated; however, there are some alternative or unconventional feedstuffs that are often used for purposes other than basic feeding or modifying the fatty acid profiles of milk, such as tanniferous plants, herbs and spices, and algae. The use of these foods in dairy diets and their effects on milk fatty acid profile are reviewed in this article. The contents of selected individual FAs (atherogenic, rumenic, linoleic, α-linolenic, eicosapentaenoic, and docosahexaenoic acids) and their combinations; the contents of n3 and n6 FAs; n6/n3 ratios; and atherogenic, health-promoting and S/P indices were used as criteria for assessing the effect of these feeds on the health properties of milk fat.

“…The mammalian lignan content in livestock milk changes with the type and ratio of livestock diet; these changes also influence the composition of other constituents in milk (Petit and Gagnon, 2009;Brito et al, 2015). The components and fatty acid profiles in the milk of lactating dairy cows are influenced by their feed (Zang et al, 2021). These reported examples demonstrated the significant effects of livestock's feed on the milk composition.…”

Cynomorium songaricum is a traditional medicine and also a food material that is eaten raw or processed as tea or beverages. As a featured plant in semi-desert grasslands, C. songaricum is also eaten by the cattle and sheep in the area. This research study fed dairy sheep C. songaricum to determine the flavan-3-ols in sheep milk. Catechin (Cat), epicatechin (Epi), procyanidin A1 (A1), procyanidin A2 (A2), and procyanidin B1 (B1) were detected in sheep milk with the concentration being Epi > A2 > Cat > B1 > A1 at 24 h after the administration of C. songaricum. Neither A1 nor A2 were detected in the methanol extract of C. songaricum. Cysteine degradation of the plant revealed that in addition to Epi, A2 was the extending unit of the polymeric flavan-3-ols in C. songaricum, indicating that A2 is released digestively from the polymers and enters the milk. Procyanidin B-1 was converted to A1 on incubation in raw but not heated milk, indicating that the A1 in milk is the enzymatically transformed product of B1. Accelerated oxidation showed that the flavan-3-ols, B1, Cat, and Epi significantly protects the unsaturated triacyglycerols in the milk from oxidation. The flavan-3-ol could slow down the oxidation of glutathione and the latter may play an important role in preventing the milk triglycerides from oxidation. Flavan-3-ols are polyphenols with many health benefits. The present research revealed the antioxidant activities of flavan-3-ols that could be absorbed to sheep milk, adding new evidences for the values of these flavan-3-ols and for the milk.

“…Reportedly, okara is an effective source of proteins for lactating ewes and their twin lambs [ 24 ]. Zang et al [ 25 ] reported that okara meal can completely replace soybean meal without negatively affecting production and nutrient digestibility in early- to mid- lactation Jersey cows. Rahman et al [ 26 ] reported that the goats fed with supplemental soybean waste had a lower total dry matter intake, feed conversion ratio, and feed cost per kilogram of body weight gain than those fed with commercial pellets.…”

Pelleting experiments were carried out in this study to clarify the influence mechanism of wet-fermented soybean dregs on the forming of corn stover. The effects of addition of water or wet fermented soybean dregs on the forming quality of corn stover were comparatively studied under different corn stover particle sizes and compression displacement. The fermented soybean dregs significantly affected the relaxed density, dimensional stability coefficient, and hardness of feed pellets. The relaxed density, dimensional stability coefficient, and hardness of feed pellets increased first and then decreased with the increase of fermented soybean dregs. The forming quality of corn stover added with fermented soybean dregs was higher than that of corn stover added with the same amount of water. The mechanism allowed soybean dregs to strengthen the bonding between corn stover particles and thus improved the quality of feed pellets. A certain amount of water was favorable for corn stover pelleting, but excessive water may decrease the quality of pellets. The comprehensive analysis showed that the addition of 5%–10% fermented soybean dregs to the corn stover improved the relaxed density, dimensional stability coefficient, and hardness of feed pellets by 10.76–23.51%, 7.32–15.74%, and 33.39–454.47%, respectively.
