“…Results of our studies are in agreement with Peixoto et al (2015) who found non-significant differences of various levels of dried citrus pulp on ammonia nitrogen. This ammonia nitrogen is necessary to promote growth of fiber degrading bacteria which use ammonia nitrogen as nitrogen source, resulting in improved fiber digestion.…”

The study was planned to investigate the effects of dried citrus pulp on nutrient intake, digestibility, nitrogen balance, blood metabolites, growth performance and economics in Nilli Ravi buffalo calves. Twenty buffalo male calves of 18 to 24 months of age having 200 to 250 kg body weight were used in a randomized complete block design. Four iso-caloric and iso-nitrogenous diets containing 5, 10, 15 and 20% dried citrus pulp were formulated. The experiment lasted for adaptation period while last five days of each month served as collection period. Feed was offered ad libitum twice a day. Animals were weighed fortnightly before morning feeding to assess their growth performance. The results showed non-significant effects of various levels of dried citrus pulp on nutrient intake and digestibility. Nitrogen metabolism was also remained unaltered among the treatments. There were non-significant differences in weight gain and blood metabolites in calves fed various levels of dried citrus pulp. However, a linear reduction in price per kg diet was observed as the level of dried citrus pulp was increased from 5 to 20% in the diet. The study showed that dried citrus pulp can be used successfully up to 20% in the diet of calves without any ill effect on feed intake, digestibility and growth performance.

“…In our study, we incubated CBP and MT as energy and nitrogen sources in supplemented media with inorganic nitrogen and organic nitrogen sources. A recent study by Peixoto et al (18) reported higher values for CP (6.0), NDF (18.3), and ADF (13.7% DM) in citrus pulp, whereas the OM content of our CBP was higher than that reported by Miron et al (6), 91.2% DM. In earlier research both the NRC (19) and Miron et al (6) found different contents of CP (6.9%, 6.70%), NDF (24%, 21.6%), and ADF (22.2%, 21.2%) in % DM basis.…”

In order to evaluate rumen microbial activity, the effects of two nitrogen sources (organic and inorganic) were analyzed in vitro by inoculating dairy cow rumen fluid and using citrus byproduct (CBP) and milk thistle (Silybum marianum, MT) as energy source substrates. The experimental design was 2 × 3 where we used three different nitrogen sources (N1: no nitrogen added, N2: ammonium bicarbonate, N3: sodium glutamate) with a basic concentration of nitrogen (100 mg/1 L). Culture pH, dry matter degradability %, ammonia-N (NH 3-N), total volatile fatty acids (TVFAs), individual volatile fatty acid proportions, and acetate propionate ratio (A:P) were measured after 24 h of fermentation. Culture pH values were in the optimal range with CBP and MT in all media. Supplementing nitrogen sources had similar tendencies to increase dry matter degradability (P < 0.01) and NH 3-N production in N2 and N3 with MT and CBP. Glutamate significantly (P < 0.01) increased TVFAs, which were twice as high than in N1 and N2 with MT. These results show that N supplementation had minor effects on in vitro rumen microbiota activity compared to N1; however, it could be proposed to improve microbial biomass production in mixed rations of agricultural byproducts with local forages.

“…In one study, Macias [79] reported an increase in carcass pH up to 45 min postmortem with the dietary inclusion of Ferulic acid from winery by-products in ruminant diets. Several studies have reported that carcass traits were not affected by dietary inclusion of citrus and winery by-products in ruminant diets, except for dressing percentage, which was reduced with the addition of these fruit by-products in ruminant diets [50,[80][81][82][83]. In another trial, Kafantaris [76] observed that an inclusion level of up to 100 g/kg DM of citrus and winery by-products in ruminant diets increased slaughter, warm, and cold carcass weights and longissimus muscle area.…”

Citrus and Winery Wastes: Promising Dietary Supplements for Sustainable Ruminant Animal Nutrition, Health, Production, and Meat Quality

Citrus and grapes are the most widely grown fruits globally, with one-third of total production used for juice and wine making. The juice and winemaking processes generate large quantities of solid organic wastes including citrus pulp and grape pomace. These fruit wastes pose serious economic, environmental, and social challenges, especially in low-to-middle-income countries due to financial, technological, and infrastructural limitations. They are, however, rich in valuable compounds which can be utilized in the ruminant livestock industry as novel, economical, and natural sources of cellulose, polyunsaturated fatty acids, and phytochemicals, which have nutritional, anthelmintic, antioxidant, and antimicrobial properties. Despite citrus and grape fruit wastes having such potential, they remain underexploited by the livestock industry in low-to-middle-income countries owing to lack of finance, skills, technology, and infrastructure. Inclusion of these fruit wastes in ruminant diets could combine the desirable effects of enhancing animal nutrition, health, welfare, production, and meat quality attributes with the prevention of challenges associated with their disposal into the environment. The current review explores the valorization potential of citrus and winery wastes as dietary supplements to sustainably enhance ruminant animal nutrition, health, welfare, production, and meat quality.
