Impact of different dietary fibre sources on production performance, bacterial composition and metabolites in the caecal contents of rabbits
This study was conducted to investigate the effects of different dietary fibre sources on growth performance, gastrointestinal tract development, caecal fermentation and bacterial composition in the caecal contents of rabbits. A total of 120 35-day-old weaned Minxinan black rabbits were divided into three groups and fed a diet composed of peanut straw powder (Group A), alfalfa powder (Group B) and soybean straw powder (Group C) as the main fibre source. The final body weight and average daily gain  in Group B were higher than those in Group C, and the average daily feed intake and feed conversion ratio in Group A were lo...

Calcitriol combined with fish oil in the diet of Chukar partridge can ameliorate laying performance by improving oviduct histomorphometry and functions
AbstractThe effects of calcitriol (CT) and/or fish oil (FO) on performance, oviposition time, sex ratio  and morphology of the reproductive system of laying Chukar partridges were studied. Female (n = 48) and male (n = 16) partridges were used in a completely randomised design using a 2 × 2 factorial arrangement and were randomly allocated to either of four experimental treatments with four cage replicates of three females and one male each. Female birds received no FO (CON −  FO) or were orally administered with 0.2 mL (0.24 g)/500 g body weight FO (CON + FO) or 0.2 mL solution containing 1...

MicroRNA ‐27a inhibits porcine type I muscle fibre gene expression by directly targeting peroxisome proliferator‐activated receptor‐γ coactivator‐1α
AbstractMicroRNAs are one of the key determinants of muscle fibre development and phenotype in mammals. The preliminary experiment implied that microRNA-27a (miR-27a) might involve in regulation of muscle fibre type composition of pigs. Thereby, the present study aimed to confirm the regulatory effect of miR-27a on porcine type I muscle fibre-encoding gene (myosin heavy chain gene 7, MYH7) expression and its related mechanism. We firstly observed opposite expression patterns between miR-27a and MYH7 as well as between miR-27a and peroxisome proliferator-activated receptor- γ coactivator-1α (PGC-1α) during differentiatio...

The quality of beef in the conditions of the former Semipalatinsk Test Site
AbstractThe territory of the Semipalatinsk Nuclear Test Site represents vast areas of grassy steppes, their use as pastures seems promising. The purpose of work was to compare beef samples obtained from settlements belonging to different categories of radiation risk: Kokpekty village, Chagan urban-type settlement, Krivinka village, Sarzhal village, three  samples were examined from each settlement. Organoleptic analysis, radiometric determination of137Cs, was used as criteria. Also, an analysis of the amino acid composition by the high-performance liquid chromatograph method was carried out and a calculation of protein in...

Animal protein ‐soybean oil‐based broiler diet optimizes net profit at the expense of desirable ω‐6 fatty acids from the breast muscle of the broiler chicken
AbstractTotal 288 Ross-308-day-old male broiler chicks were randomly distributed into six dietary treatment groups in a two-way ANOVA with 2  × 3 factorial arrangements (two factors, i.e., dietary protein and energy having two types of protein, e.g., plant, animal and three different sources of energy, e.g., soybean oil, rice bran oil and sunflower oil) to justify if animal protein-soybean oil based broiler diet optimizes net profit at the expense of desirable ω-6 fatty acids in the breast muscle of the broiler chicken. Average daily feed intake (ADFI), final live weight (FLW), average daily gain (ADG), feed efficien...

mTORC2 ‐AKT‐LAT1 signalling participates in methionine‐induced β‐CASEIN expression in mammary epithelial cells of dairy cows
This study investigated the role of the mammalian target of rapamycin complex 2 (mTORC2)-protein kinase B (AKT) signalling in methionine (Met)-induced L-type amino acid transporter 1 (LAT1) expression and milk protein production. Primary mammary epithelial cells (MECs) from mammary parenchymal tissues of three lactating cows and MAC-T bovine MECs were cultured with or without 0.6  mM Met. Rapamycin-insensitive companion of mTOR (RICTOR) siRNA, the mTORC1 inhibitor rapamycin and the AKT activator SC79 were used to evaluate the effects of mTORC2-AKT signalling on Met-induced LAT1 expression and function. Each experiment wa...

In vitro aflatoxins recovery after changing buffer or protozoa concentrations in the rumen fermentation fluid
In conclusion, the rumen in vitro AFB1 recovery (63%–75%) was higher than other AFs (3%–46%) and the acidic f ermentation environment increased it. In our conditions, changes in protozoa numbers did not affect AFs recovery. (Source: Journal of Animal Physiology and Animal Nutrition)

Milk production and milk fatty acid profile as a response to feeding dairy cows with flax products during the persistence period
AbstractThe response of enhanced dietary dairy cows with linolenic-rich sources during the persistence period was studied to determine its effectiveness on some blood constituents, milk yield and milk fatty acid profile. A complete randomized design experiment was conducted in the spring and involved 20 Friesian cows (60 days in milk) that were divided into four groups of five animals by milk production according to different types of flax source in isonitrogenous and isoenergetic rations: a traditional diet with no flax source (CO), a diet contains flaxseed meal (FLM), a diet contains whole flaxseed (FLS) and a diet conta...

A pilot investigation on the effect of induced saliva flow on digestive parameters in sheep, and a comparison with cattle
AbstractSheep with a relatively low methane yield were observed to have shorter fluid and particle mean retention times (MRT). Because the application of pilocarpine, a saliva stimulant, was successful in reducing retention times in ruminants in previous studies, we applied this substance to sheep, expecting a reduction in MRT and methane yield. Three non-pregnant sheep (74  ± 10 kg) were fed a hay-only diet in a 3 × 3 Latin square design with oral doses of 0, 2.5 and 5 mg pilocarpine/kg body weight and day. Measurements included feed and water intake, MRT of liquid and particulate phases in the reticulorumen...
