Evaluation of the use of probiotics in diets with or without growth promoters for broiler chicks

Revista Brasileira de Zootecnia (2010)

Régis Fernando Pastorelo Meurer Paula Carvalho Leal Chayane da Rocha I. J. M. Bueno Alex Maiorka

This work was carried out to evaluate the use of Bacillus subtilis probiotic C-3102 (10(10)cfu/g) in diets with or without growth promoters on the performance of broilers in the period from 1 to 42 days of age. It was used 1,200 Cobb line broilers, distributed in a complete randomized block with five diets: negative controller (without promoters); Bacillus subtilis (30 g/t ration); Bacillus subtilis (50 g/t ration); Bacillus subtilis (30 g/t ration) + colistin (10 ppm); avilamycin (10 ppm) + colistin (10 ppm). Each diet was evaluated in 10 repetitions with 24 birds. From 21 to 42 days of age, feed intake, weight gain and feed conversion were evaluated, and at 42 days of age, productive efficiency index was evaluated. At the end of the experimental period, it was observed an increase in the consumption of diet with the lowest dose of Bacillus subtilis (30 g) in relation to that one with Bacillus subtillis (30 g) + colistin (10 ppm). The values of weight gain obtained with the diet with the lowest dose of Bacillus subtillis (30 g) and with avilamycin (10 ppm) + colistine (10 ppm) were higher than those of the birds fed control diet (without promoters). For feed conversion, the best results were obtained by supplying diets containing 50 g of Bacillus subtillis, diet with 30 g of Bacillus subtillis + 10 ppm of colistin; and diet with 10 ppm of avilamycin + 10 ppm colistin. For the analysis of productive efficiency index, the best results were obtained with diets containing additives (probiotics and/or antibiotics) in comparison to the control diet. Bacillus subtillis C-3102 probiotic, at concentration 10(10) cfu/g, is an efficient substitute of antibiotics.

Growth of suckling piglets in litters standardized by weight

Journal of Animal Science (2013)

D. Surek Lucas Newton Ezaki Barrilli I. J. M. Bueno E. L. Krabbe Geraldo Camilo Alberton

This study examined the relationship between birth weight and growth performance when suckling piglets were reared in litters standardized by birth weight. Forty-four gilts (Landrace × Large White) due to farrow during the same week were selected. Piglets born to those gilts were individually weighed at birth and cross-fostered to obtain litters with 11 piglets and standardized birth weight (CV, lower than 5%). Based on average birth weight, 4 litter weight classes were established: class 1 (> 1.10 kg to ≤ 1.33 kg), class 2 (> 1.34 kg to ≤ 1.46 kg), class 3 (> 1.47 kg to ≤ 1.57 kg), and class 4 (> 1.58 kg to ≤ 1.88 kg). At 21 d of age, piglets were weighed to determine BW and calculate ADG and weight gain relative to birth weight. A completely randomized experimental design was used with birth weight classes as treatments. At 21 d of age, the average BW of piglets from the heaviest birth weight class (5.67 kg) was greater (P < 0.05) than the lightest class (5.06 kg); however, all classes had the same ADG (P < 0.05). There was a positive correlation (r = 0.184; P < 0.01) between birth weight and weight at 21 d of age, but birth weight was not correlated (r = -0.040; P = 0.37) with ADG during the suckling phase. Therefore, piglet birth weight did not influence weight gain when piglets were reared by sows in litters with standardized birth weight.

Effects of different limestone particle sizes in the diet of broiler breeders post molting on their performance, egg quality, incubation results, and pre-starter performance of their progeny

Poultry Science (2016)

I. J. M. Bueno D. Surek Chayane da Rocha V.G. Schramm Keysuke Muramatsu

An experiment was conducted to test the hypothesis that a coarse limestone diet improves productivity, reproductive performance and the calcium utilization of molted broiler breeders. In total, 640 broiler breeder females, 73-week-old and sixty-four 27-week-old cockerels, Cobb 500, were evaluated during 10 weeks, according to a randomized block design composed of 4 treatments with 8 replicates each. Treatments consisted of diets with the inclusion of 100% fine limestone - fine PS (0.2 mm GMD - geometric mean diameter); PS1: 30% fine limestone + 70% limestone with 1.0 mm GMD; PS2: 30% fine limestone + 70% limestone with 2.0 mm GMD; and PS3: 30% fine limestone + 70% limestone with 3.0 mm GMD. Calcium retention in the gizzard of the breeders, bone characteristics, and breeder performance, egg characteristics, eggshell quality, incubation performance, chick quality and yield, chick pre-starter live performance, and chick bone characteristics were determined. There was no significant difference (P > 0.05) in the rate of lay, percentage of non-settable eggs, egg weight, egg shape index, egg specific gravity, eggshell weight, thickness, and percentage hatchability and egg weight loss of broiler breeders fed with diets with different limestone particle sizes. The chick quality and yield, chick pre-starter live performance, and chick bone characteristics were not affected (P > 0.05) by any of the limestone particle sizes. It was concluded that live and reproductive performance parameters of broiler breeders post molting is not affected by limestone particle size in the feed.

Vitamin E and selenium in broiler breeder diets: Effect on live performance, hatching process, and chick quality

Poultry Science (2015)

U.R.A. Urso Fabiano Dahlke Alex Maiorka I. J. M. Bueno Aline Félix Schneider

This study evaluated the effect of different dietary vitamin E levels and different selenium sources on the productive and reproductive performance of broiler breeders. In total 640 females and 64 males between 22 and 52 weeks old were studied. A completely randomized experimental design in factorial arrangement, with 4 treatments of 8 replicates with 20 females and 2 males each, was applied. Treatments consisted of 2 vitamin E levels (30 and 120 mg/kg) and two selenium sources (sodium selenite and zinc-L-selenomethionine). Egg production (rate of lay and eggs per breeder), egg characteristics (egg, yolk, eggshell, and albumen weights), fertility, incubation responses (egg weight loss during incubation, hatchability, and hatching window), and hatchling characteristics (weight and yield) were evaluated. There was no influence of dietary vitamin E levels or selenium sources on egg production (P > 0.05). Mature breeders (47 weeks old) fed zinc-L-selenomethionine and 120 mg vitamin E/kg feed produced heavier eggs and albumen. Hatchability of the eggs of breeders fed 120 mg vitamin E/kg feed was higher than breeders fed 30 mg vitamin at 29 wks. The dietary inclusion of organic selenium also promoted heavier hatchling weight until egg production peak (33 wk), but did not influence hatchling quality or hatching window. It was concluded that the dietary supplementation of zinc-L-selenomethione and vitamin E (120 mg/kg feed) could be used to improve egg characteristics and incubation response.
