“…These components have many properties, such as anticarcinogenic, anti-inflammatory, antioxidant, and antimicrobial [15]. Many studies have reported that these PSCs enhance rumen fermentation characteristics by reducing methane emission and increasing animal productivity [16][17][18]. For instance, Wall, et al [19] reported that a blend of plant extracts containing cinnamaldehyde, the main bioactive of cinnamon, can increase milk production and dry matter intake in lactating dairy cows.…”

Background In recent years, researchers have become increasingly interested in developing natural feed additives that can stabilize ruminal pH and thus prevent or eliminate the risk of severe subacute rumen acidosis. Herein, 3 experiments were conducted using a semi-automated in vitro gas production technique. In the experiment (Exp.) 1, the efficacy of 9 plant extracts (1.5 mg/ml), compared to monensin (MON; 12 μg/ml), to counteract ruminal acidosis stimulated by adding glucose (0.1 g/ml) as a fermentable carbohydrate without buffer was assessed for 6 h. In Exp. 2, cinnamon extract (CIN) and MON were evaluated to combat glucose-induced acidosis with buffer use for 24 h. In Exp. 3, the effect of CIN and MON on preventing acidosis when corn or barley grains were used as substrate was examined. Results In Exp. 1, cinnamon, grape seeds, orange, pomegranate peels, propolis, and guava extracts significantly increased (P < 0.05) pH compared to control (CON). Both CIN and MON significantly increased the pH (P < 0.001) but reduced cumulated gas production (P < 0.01) compared to the other treatments. In Exp. 2, the addition of CIN extract increased (P < 0.01) pH value compared to CON at the first 6 h of incubation. However, no significant differences in pH values between CIN and CON at 24 h of incubation were observed. The addition of CIN extract and MON decreased (P < 0.001) lactic acid concentration and TVFA compared to CON at 24 h. The CIN significantly (P < 0.01) increased acetate: propionate ratio while MON reduced it. In Exp. 3, both CIN and MON significantly increased (P < 0.05) ruminal pH at 6 and 24 h and reduced lactic acid concentration at 24 h compared to CON with corn as substrate. However, CIN had no effect on pH with barley substrate at all incubation times. Conclusions It can be concluded that CIN can be used effectively as an alternative antibiotic to MON to control ruminal acidosis when corn is used as a basal diet.

“…Moreover, the low quality and quantity of animal feeds are serious problems that limit the productivity of livestock worldwide. The importance of shrubs, trees, and herbs as fodder sources has been suggested because of their nutritional value (when compared with fodder trees, herbs, grasses, and shrubs with relatively higher levels of neutral detergent fiber, minerals, and crude protein) for grazing animals in low-quality grazing areas for long periods of the year [3,4]. Nowadays, nutritional solutions and strategies are being used to resolve these crises by using alternative feed ingredients, such as tropical and subtropical plants in rabbit rations [5].…”

This experiment was conducted to study the effects of paulownia leaf meal (PLM) as a nontraditional feed on the growth, carcasses, digestibility, blood chemistry, and intestinal microbiota of growing rabbits. Sixty rabbits (5-weeks old) were randomly allotted to three dietary treatments containing three amounts of PLM (0%, 15%, and 30%). The results showed that PLM has a higher content of ether extract, organic matter, methionine, tyrosine, histidine, manganese, and zinc than alfalfa hay. Body weight gain decreased when 30% PLM was provided. The best feed conversion ratio was recorded in the rabbits fed 15% PLM. A notable increase in high-density lipoprotein levels with a significant decrease in low-density lipoprotein was noted in the rabbits fed the PLM diets. Total fungi and Enterobacteriaceae and total bacterial count in the feed were significantly reduced because of PLM. In the cecum, coliforms, Enterobacteriaceae species, and total bacterial count declined in the rabbits fed the PLM diets. Conclusively, up to 15% PLM can be used in rabbit diets without any deleterious effects on the performance, nutrient digestibility, and blood constituents. In addition, dietary inclusion of PLM has the potential to reduce cecal pathogenic bacteria in rabbits.

“…In a study conducted in Thailand, it was determined that the DM and protein degradability in guava leaves are high (71%) and it is a high-value feed for cattle (Paengkoum et al, 2012). Al-Sagheer et al (2018) stated that when 25% of guava leaves are used in the diet, there is no harmful effect on ruminal degradability of nutrients and may be an alternative contribution in reducing CH4 production. Hassan et al (2016) state that dried guava wastes can be used effectively in the diet at a rate of 20% without adversely affecting the performance, digestibility, carcass characteristics or health parameters of Ossimi lambs.…”

Roughages have vital importance in the diet of ruminants because they are cheap and absolutely necessary for digestive physiology. Ruminant nutrition requires quality feeds to obtain high amounts of product. As more than half of the business inputs are made up of feed expenses, the necessity of high-quality roughage sources, which are cheaper compared to concentrate, arises. The high quality of roughage means that the amount of mixed feed that can be put into the ruminant ration to meet the nutrient requirement is less. Thus, the cost of the product to be obtained will decrease and the net profit will increase. Since the leaves of some plants grown in the tropical region and the fruits and shells that cannot be used as human food are not utilized, they cause environmental pollution, and the feed cost cannot be reduced because the vegetable waste is not used in animal feeding. Many tropical plant leaves and waste are rich in protein and crude fiber. Crude protein levels in the leaves of some tropical plants can be up to 30%. The usability of tropical plant leaves and fruit peels, which are rich in nutrients, as roughage has not been adequately studied. These plants can be used as an alternative roughage source for ruminants in times of shortage of quality roughage and in times of famine, increasing animal production and preventing problems in the environment. The purpose of this review is to examine the possibilities of using leaves and fruits and wastes of some tropical plants (Guava, papaya, banana, mango, pineapple, cassava, moringa and avocado) as an alternative roughage source in ruminants.
