Feed synbiotic additive to improve the productivity and quality of rabbit meat

Abstract

The study is dedicated to research into efficiency of influence of probiotic additive “Prostor” on productivity, chemical composition of meat of rabbits. The influence of synbiotic preparation “Prostor” on the population of male rabbits of hybrid form “Hypharm” of French breeding, selected at the age of 45 days. The study took place at the industrial complex of LLC “Lipetsk rabbit” in Khlevensky district of Lipetsk region. The animals were divided into control and experimental groups by the method of pairs-analogues. The control group of rabbits received the basic diet consisting of lall-mash feed PZK-92, while the rabbits of the experimental group received compound feed PZK-92-60-18, which included synbiotic “Prostor” in a dosage of 1 g/kg of feed. Meat quality assessment was carried out at the age of 105 days after control slaughter in the amount of 3 animals from each group. The use of the stated dosage of synbiotic preparation had a positive effect on the productive indicators of rabbits (live weight, average daily growth). The morphological composition data showed that rabbits of the experimental group outperformed rabbits of the control group by 23.84 % in terms of muscle mass. Analysis of the chemical composition of muscle tissue showed that the use of feed additives “ProStor” in a dosage of 1.0 g per kg of feed has a positive effect on meat productivity and quality of rabbit meat, which opens up prospects for the use of the preparation in the rabbit industry.

Determination of influence of modes of storage fruit and vegetable products in its condition

“…With cording to other publications modern volume of consumption of fresh vegetables, potatoes and fruits in Ukraine is 50-60% of the physiological norm. [7] Potero in storage potatoes, vegetables and fruit make up 20-30% annually. [8] Investing in storage products is 2-3 times more efficient than in the expansion of its production.…”

Current Prospects of Nutraceuticals in Rabbit Productivity and Health – an Updated Review

“…Synbiotics are a synergistic mixture of probiotics and prebiotics, as they support growth and survival of probiotics and boost their health benefits in the gut. Studies proved that dietary synbiotics enhanced growth performance in growing rabbits (Hassanin et al, 2015;Ali and Hassan, 2018;Kurchaeva et al, 2020;Nwachukwu et al, 2021). Kurchaeva et al (2020) reported that dietary synbiotic (1 g/kg diet) enhanced growth performance (BW and BWG), carcass traits (cooled carcass weight and dressing %), meat chemical composition (increased meat protein, Na, Ca, K, and P contents, while reduced meat fat content), meat physical traits (water-holding capacity, moisture binding capacity, fat holding capacity ability, emulsifying ability, and emulsion stability).…”

Similarly, Nwachukwu et al (2021) reported that dietary synbiotics (combination of 400 mg prebiotics/ kg diet + 50 mg probiotics/ kg diet) improved growth performance (final BW, BWG, and FCR) and intestinal histomorphology parameters (ileal villus height, villus width, villus density, crypt depth, and villus height: crypt depth ratio).…”
