Impact of Leaves on Nutrient Utilization, Enteric Methane Emissions, and Performance of Goat Kids.

The development of different innovative feed resources for livestock is important to provide the essential nutrients and diminish the emission of greenhouse gases. The purpose of the present experiment was to study the response of replacing concentrate with Moringa oleifera leaves in terms of the nutrient intake, digestibility, enteric methane emissions, and performance of goat kids with a berseem-fodder-based diet under different roughage (R)-to-concentrate (C) ratios. Twenty-four goat kids (3 months of age) were distributed into four groups of six animals each, using a randomized block design (RBD).

Impact of Moringa oleifera on rumen fermentation and methane emission under in vitro condition.

Exploring innovative methods to provide essential nutrients and reducing ruminant greenhouse gas emission is crucial for animal production and diminishing global warming. This study was conducted to examine the efficacy of Moringa oleifera leaves (ML) in ruminants at 0%, 5%, 10%, 15%, 20%, 30% and 40% level in different roughage (R) and concentrate (C) (80R:20C, 70R:30C and 60R:40C) under in vitro conditions. Chemical composition of ML, concentrate mixture and berseem were estimated.

Effect of supplementing Leucaena leucocephala leaves alone or in conjunction with malic acid on nutrient utilization, performance traits, and enteric methane emission in crossbred calves under tropical conditions.

Dietary strategies aiming at minimizing enteric methane (CH) emission in ruminants are of practical interest from nutritional, economical, and environmental point of view. The present study evaluated the effects of supplementing Leucaena leucocephala leaves either alone or in conjunction with malic acid on nutrient utilization, growth performance, and enteric CH emission in crossbred cattle fed wheat straw and concentrate-based diet under tropical conditions. Eighteen crossbred (Karan-Fries) calves were randomly allocated into 3 groups: G-I (control)-fed wheat (Triticum aestivum) straw and concentrate mixture in the ratio 50:50; G-II-fed wheat straw, concentrate mixture, and Leucaena leucocephala leaves in the ratio 45:45:10; and (3) G-III-fed similar diet like G-II with an additional supplementation of 1% malic acid on dry matter intake basis.

Effects of monensin feeding on performance, nutrient utilisation and enteric methane production in growing buffalo heifers.

Murrah buffalo heifers (live weight 135 ± 17 kg) were fed a total mixed ration without supplementation (CON), or supplemented with sodium monensin (MON; Rumensin® 200, Elanco Animal Health, Brazil) @ 0.6 mg/kg of body weight for 90 days. Nutrient digestibility and nitrogen retention were estimated during the mid-experiment, and enteric methane production was measured by sulphur hexafluoride tracer technique for consecutive-5 days after the digestion trial.

Growth performance, and enteric and manure greenhouse gas emissions from Murrah calves fed diets with different forage to concentrate ratios.

The present study investigated the effects of different dietary forage to concentrate ratios on animal performance, and enteric and manure greenhouse gas emissions in growing calves. Fifteen male Murrah calves (153.5 ± 18.

Nutrient utilisation and methane emissions in Sahiwal calves differing in residual feed intake.

The presented study aimed at investigating the residual feed intake (RFI) of Sahiwal calves, nutrient utilisation as affected by RFI and its relationship with methane (CH4) emissions and some blood metabolites. Eighteen male Sahiwal calves (10-18 months of age; mean body weight 133 kg) were fed ad libitum with a total mixed ration. After calculating RFI for individual calves (-0.

Methane emissions from river buffaloes fed on green fodders in relation to the nutrient [corrected] intake and digestibility.

Fifteen male Murrah buffalo calves (15-18 months, 227.98 ± 4.44 kg body weight) were distributed randomly in to three equal groups and fed solely on either berseem (G1), oats (G2), or chicory fodder (G3).

Nutritional evaluation of wheat straw treated with Crinipellis sp. in Sahiwal calves.

Wheat straw was subjected to solid-state fermentation (SSF) with lignolytic white-rot fungus (WRF) Crinipellis sp. for 5 days to improve the nutritive value and digestibility. The fungal treatment caused a significant (P < 0.

Evaluation of complementary effects of 9,10-anthraquinone and fumaric acid on methanogenesis and ruminal fermentation in vitro.

The objective of the present study was to investigate the hypothesis that 9,10-anthraquinone (AQ) in combination with fumaric acid (FMA) may provide complementary effects to inhibit methanogens and enhance rumen's capacity for better utilisation of FMA towards propionate production. Three levels of AQ and four levels of FMA were tested in a 3 x 4 factorial design using in vitro gas production technique. AQ reduced the total gas and methane production significantly.
