Effect of using different levels of Protexin probiotic on performance, some carcass traits and intestinal microbial population of Japanese quails

This study was carried out to determine the influence of different levels of alfalfa meal and the addition of enzyme on performance, carcass and intestinal parameters in growing quails. Japanese quails (n=240), 1 days of age, were divided into 6 dietary treatment groups and the experiment lasted for 5 weeks. In each experiment group there were 4 replicates, and in each replicates there were 10 chicks. Six diets, arranged a factorial design with three alfalfa meal levels (0, 2.5 and 5.0 %) and two levels of added enzyme (0.0 and 1.0 g/kg) were used. The treatments did not effect on the body weight, feed intake and feed conversion ratio. However, relative liver, leg+back, intestine weights and crypt depth were significantly increased, and relative heart and breast weights and villus width decreased by dietary alfalfa meal levels. The addition of enzyme to diets containing alfalfa meal did not affect the performance and carcass parameters, but reduced the intestinal histomorphology parameters in quails. According to the results obtained from the experiment, it can be said that the use of alfalfa meal in growing quail diets did not affect the performance, but the use of alfalfa meal at the level of 2.5% in the diet promotes intestinal development.

Crude Protein Level

Two biological trials were conducted to determine the energy and lysine requirements of “TANUVAS Namakkal gold Japanese quail” for production performance. The economic impact of different levels energy and lysine during the chick (0-2 weeks) and grower (3-5 weeks) phases was assessed using seven hundred and twenty straight-run, day-old chicks randomly grouped in nine treatments with four replicates of twenty chicks each. Three levels of energy (2800, 2900 and 3000 kcal/kg) and three levels of lysine (1.2, 1.3 and 1.4%) were tested for chick and grower phase of the first experiment. The net profit per bird (Rs. 8.49) was high in group T1 (low energy and low lysine) and the net profit per kg live weight (Rs. 48.57) was high in T2 (2900 kcal/kg and 1.2%). For the second experiment an energy level of 2700, 2800 and 2900 kcal/kg was fixed for chick and grower mash, lysine level of 1.2, 1.3 and 1.4% was fixed for chick phase and 1.1, 1.2 and 1.3% for grower phase and the crude protein level was fixed as 20.3 and 19.4 per cent for chick and grower mash respectively for the second trial. The net profit per bird (Rs. 7.18) was high in group T6 and the net profit per kg live weight (Rs. 37.62) was high in T6 (2900 kcal/kg and 1.3% lysine during chick phase and 1.2% lysine during the grower phase).

Live Yeast

Forty Pelibuey × Kathdin lambs (35.5 ± 0.4 kg) were used in a 56-day feeding experiment to assess the effects of feeding different levels of chromium-enriched live yeast (Cr-YC) on growth performance, dietary energetics, carcass traits and visceral organ mass. The Cr-YC source contained 5.5 × 109 colony forming units (CFU) and 0.40 mg of Cr per gram. Treatments consisted of a dry rolled corn-based finishing diet supplemented with 0, 1, 2 or 3 g Cr-YC/lamb.day. Total daily dosages were: 5.5 × 109 CFU and 0.4 mg; 1.1 × 1010 CFU and 0.8 mg Cr, and 1.65 × 1010 CFU and 1.2 mg Cr for supplementation levels of 1, 2 or 3 g Cr-YC/lamb.day, respectively. There were no treatments effects on dry matter intake. As the level of Cr-YC supplementation increased, average daily gain, gain to feed and dietary net energy were linearly increased, and observed/expected dry matter intake was linearly decreased. Chromium-enriched live yeast supplementation increased empty bodyweight (EBW), gastrointestinal fill and full viscera weight, but did not influence organ weights as a proportion of EBW (g/kg EBW). Cr-YC level did not affect carcass length, backfat thickness, kidney, pelvic and heart fat or body wall thickness, but increased hot carcass weight and longissimus muscle area. In general, treatment effects on percentage yield of wholesale cuts (tissue weight as a percentage of cold carcass weight) were small. However, Cr-YC decreased percentage flank. Chromium-enriched yeast supplementation enhances growth rate, longissimus muscle area, and dietary energetic efficiency in finishing feedlot lambs.
