“…In the present study, Caat inclusion reduced the A:P ratio around 15% compared with negative control, a similar reduction to that found by Kholif et al (2018) when evaluating doses of Moringa oleifera leaf extract on feed intake, nutrient digestion, and ruminal and blood serum measurements in goats. On the other hand, Takiya et al (2017) evaluated the increasing dietary doses of an Aspergillus oryzae extract with alpha-amylase activity on ruminal fermentation of lactating dairy cows.…”

“…Additionally, we observed in this study that CH 4 concentration was reduced by approximately 5% with the Caat inclusion compared with AMC inclusion. Similarly, Kholif et al (2018) described a 7% decrease in CH 4 (mmol/L) in ruminal fluid of goats fed Moringa oleifera leaf extract. Moreover, a reduction of 19% in CH 4 (g/DM) production was reported by Cattani et al (2016), when evaluating the inclusion of pure oils extracts (limonene, allyl sulfide, cinnamaldehyde, and eugenol) on in vitro ruminal fermentation.…”

Ruminants Full-length research article In vitro evaluation of novel crude extracts produced by actinobacteria for modulation of ruminal fermentation ABSTRACT-We evaluated the inclusion of two crude extracts produced by Streptomyces genus on in vitro dry matter and organic matter digestibility (IVDMD; IVOMD), cumulative gas production, volatile fatty acids (VFA), and methane (CH 4) and ammoniacal nitrogen (NH 3-N) concentration. The experimental design was randomized blocks with three blocks and four treatments: AMC (1.2 mg/25 mL ruminal inoculum), Caat (1.2 mg/25 mL ruminal inoculum), negative control (no inclusion of extracts), and positive control (sodium monensin, 1.7 mg/25 mL ruminal inoculum). Ruminal fluid samples were collected from three multiparous Holstein dairy cows fitted with ruminal cannula and incubated in a 24-h fermentation assay. There was no effect of crude extract inclusion in comparison with negative control on cumulative gas production in 24 h. However, cumulative gas production was lower when Caat extract was included in comparison with AMC inclusion. The Caat inclusion increased propionic acid concentration and reduced the concentration of butyric acid and acetate:propionate (A:P) ratio in relation to negative control. The CH 4 concentration was lower with Caat inclusion in relation to AMC, and the ratio of CH 4 concentration to digestible dry matter was lower in the negative control compared with all additives. Caat inclusion decreased the NH 3-N concentration, and IVDMD was not altered compared with negative control. Additionally, the inclusion of Caat crude extract increased propionic acid concentration and reduced butyric acid concentration and A:P ratio, without reducing the IVDMD and IVOMD. Caat extract modulates rumen fermentation, increasing available energy and decreasing gas production without causing changes in dry matter and organic matter digestibility.

“…High levels of secondary metabolites have detrimental effects on feed utilisation (Salem et al 2014). However, recent reports stated that low and medium levels of secondary metabolites have some positive effects on ruminal fermentation and productivity in vivo (Cedillo et al 2015; Kholif et al 2018) and in vitro (Chaudhry & Khan, 2012). Ruminal microflora has the ability to degrade and utilise low and moderate concentrations of the secondary metabolites without negative effects on animal performance and ruminal fermentation (Kholif et al 2015, 2018).…”

The experiments reported in this Research Paper aimed to study the effects of mustard and cumin seeds inclusion on feed utilisation, milk production, composition, and profile of milk fatty acids in lactating Damascus goats. The study was a completely randomised design with repeated measurements in time using fifteen goats (6 ± 2 d of lactation) divided into 3 treatments (5 goats per treatment). Goats were offered a control diet of berseem clover and concentrates (1 : 1 dry matter (DM) basis) or the control diet supplemented with either 10 g/d of dried mustard seeds (mustard treatment) or 10 g/d of cumin seeds (cumin treatment) for 12 weeks. Treatments had no effect (P > 0·05) on feed intake, but enhanced (P < 0·05) digestibility of DM, organic matter, non-structural carbohydrates, and fibre fractions. Digestibility was greater (P < 0·001) with cumin treatment compared with mustard treatment. Mustard and cumin seeds had greater (P < 0·05) ruminal total short chain fatty acids (SCFA) production, and molar proportion of propionate, with greater (P < 0·001) SCFA production for cumin vs. mustard treatment. Mustard and cumin seeds increased (P < 0·05) concentrations of serum total proteins, globulin, and glucose and lowered (P < 0·05) serum cholesterol concentration. Mustard and cumin seeds inclusion elevated milk production (P = 0·007), while cumin increased milk contents (P < 0·05) of fat and lactose. Cumin treatment lowered (P < 0·05) milk saturated fatty acids (SFA) and had greater total unsaturated fatty acids (UFA) and total conjugated linoleic acid (CLA) contents. Overall, supplementing diets of Damascus goats with mustard or cumin seeds at 10 g/daily enhanced feed digestion, ruminal fermentation, milk yield (actual production by 6·8 and 11·1%, and energy corrected milk yield by 10·1 and 15·4%, respectively) and positively modified milk fatty acid profile with a 3·9% decrease in milk individual and total SFA, and an increase in individual and total UFA by about 9·7%, and total CLA by about 23·1%.

“…183 vs. 164 g/day). Likewise, very positive results were reported by Kholif et al (2018) from oral doses of an extract from MO leaves. Nubian goats in early to mid-lactation consumed a 40% forage (berseem clover) diet; however, BW and DM intake relative to BW again appeared lower than expected (initial BW of 36.5 kg and DM intake of 2.1-2.3% BW).…”

Dairy goats can mobilize considerable body fat for support of milk production, but this can necessitate a high nutritional plane later for replenishment. Tissue mobilization during gestation should be controlled so as not to impair lactational performance. Dairy goats can markedly vary feeding behaviour in response to factors such as restricted periods of access; however, further studies are needed to address the efficiency of production. With some tolerance of goats to plant secondary metabolites and voluntary consumption of a wide array of materials, regionally available byproducts and other nonconventional feedstuffs can be used to minimize production costs. Dairy goats are resilient to moderately harsh environmental conditions, but more extreme ones should be addressed with anticipated future climate change. Some differences in the effects of dietary inclusion of fats and oils between dairy goats and cattle may relate to ruminal microbial conditions as well as the susceptibility of mammary gland enzymes to bioactive conjugated linoleic acid isomers. Much research is being conducted to improve the fatty acid composition of fat in goat milk in regard to effects on human health through the use of fats and oils as well as plant secondary metabolites, and effects on antioxidant status are increasingly being considered as well.
