Variation among individual beef cattle in methane ‐to‐carbon dioxide ratio measured under on‐farm conditions using the sniffer method
This study proposed a method for measuring the methane (CH4)/carbon dioxide (CO2) ratio from individual beef cattle under on-farm conditions and estimated the variance components of the CH4/CO2 ratio. Gas measurements were conducted using 166 Japanese Black cattle group-housed in pens equipped with individual feed bins. The gas containing the animal's breath was measured individually after concentrate feeding by covering the feed bin with a sheet with sampling inlets. Measurements were performed six times (three consecutive days, twice daily) per individual. Most of the sampled gas contained more than 1000 ppm of the me...

Ovarian dynamics in progesterone tablet ‐induced superovulation in goats assessed by magnetic resonance imaging
AbstractControlled internal drug-releasing (CIDR) devices are commonly used for superovulation in goats. However, such devices are unavailable in some countries, including Japan. In this technical note, we aimed to explore the efficacy of an alternative superovulation protocol using progesterone tablets in goats. We employed intravaginal progesterone tablets (LUTINAS ® Vaginal Tablet 100 mg) following a standard superovulation protocol. Additionally, we assessed the ovarian dynamics using 3T-magnetic resonance imaging (MRI) 1 day preceding the progesterone treatment (Day “−1”) and 3 days before the end of treatm...

Human social enrichment is linked with reduced mortality in artificially reared ewe lambs
AbstractGrowth of lambs in an artificial rearing system is key to the economic success of sheep-milking farms. Social enrichment in the form of quiet human contact has been shown to increase growth rates of lambs after weaning, perhaps by reducing stress and enhancing immune function. One hundred fourteen artificially reared dairy ewe lambs were assigned either to a Social condition receiving quiet human company in three 20-min segments per day, or a Control condition without quiet human contact. Feeding and housing conditions were otherwise identical. Starting weights for the Social (M = 6.29 kg; SD = 1.19 kg)...

Gas chromatography –mass spectrometry‐based quantitative method using tert‐butyldimethylsilyl derivatization for plasma levels of free amino acids and related metabolites in Japanese Black cattle
In this study, we developed and validatedtert-butyldimethylsilyl derivatization method using gas chromatography –mass spectrometry to quantify plasma levels of free amino acids and related metabolites in Japanese Black cattle. Of the 51 metabolites examined, 24, including 20 amino acids, one amine, and three keto acids, could be quantified. Compared with the trimethylsilyl derivatization method using gas ch romatography–mass spectrometry, which has been used for untargeted metabolomic analysis, the present method had higher analytical reliability. This method is advantageous for assessing branched-chain amino acid (BCA...

Effect of fermented tomato pomace on the growth performance, antioxidant capacity, and intestinal microflora in broiler chickens
This study was conducted to investigate the effects of tomato pomace (TP) andAspergillus niger-fermented tomato pomace (FTP) on the growth performance, some carcass traits, antioxidant status, and intestinal microflora in broiler chickens. A total of 140 Ross 308 one-day-old male chicks were allocated to one of four treatment groups consisting of five replicates of seven chicks each. Chicks were fed ad libitum with the corn-soybean based basal diet (control), the basal diet supplemented with 0.25 g/kg synthetic antioxidant, 10 g/kg TP or 10 g/kg FTP for 42 days. Dietary TP increased serum glutathione peroxidase (GPx...

Fennel seeds dietary inclusion as a sustainable approach to reduce methane production and improve nutrient utilization and ruminal fermentation
AbstractRuminants are considered a major producer of methane (CH4). Therefore, the present study aimed to determine the ability of dry fennel seeds to affect in vitro gas production and fermentation. Fennel seeds were included at 0% (Control), 0.5%, 1%, 1.5%, and 2% DM of a diet containing per kg DM: 500 g concentrate feed mixture, 400 g berseem hay, and 100 g of rice straw. The incubations lasted 48 h. Fennel seeds increased (P < 0.001) the asymptotic gas production and decreased its rate, while decreasing the production and proportion of CH4 (P < 0.05) and increased its rate. Moreover, fennel seed ...

Morphological aspects of rumen papillae of lambs fed agro ‐industrial wastes
AbstractSheep meet production systems require roughage feed of good nutritional quality. However, the production of sorghum or corn silage, besides expensive, also depends on large cultivable areas and favorable weather conditions. Thus, agro-industrial residues have stood out as a feed alternative that contribute to the reduction of production costs and to the conservation of the environment. Fragments of the ruminal mucosa of 30 healthy lambs fed with agro-industrial residues and slaughtered with a final weight of 36 kg were analyzed by light and scanning electron microscopy. We observed that the coproducts grape resi...

Comparison of plant extract ‐derived nano‐zinc particles with different zinc sources and effects of different Zn sources on egg yield and quality traits
This study aimed to compare the zinc (Zn) nanoparticles obtained from plant extracts with different zinc sources and to reveal the effects of different Zn sources on growth performance, egg quality traits and blood serum parameters of laying quail. Treatment groups as follows: control and 3 and 6 mg/kg inorganic, organic, and plant extract-derived nano-Zn particles to quail diet supplementation. Animals were fed on experimental diets for 6 weeks. Different Zn sources supplemented into quail diets did not significantly affect live weights (P > 0.05). On the other hand, different Zn sources increased egg yields (P...
