The basal formulated based corn to meet requirements chickens. polynomial regression at 5% significance. Weight gain average BW showed quadratic response (P =...

Broiler energy nutrition has attracted attention due to its economic importance, particularly during the rearing period of 22-42 days age. There are many evidences that broilers changed their feed intake capacity genetic selection, especially when good quality pellets fed, which suggests modern broiler strains may achieve performance fed low metabolizable levels. The objective was evaluate efficiency, parameters, bone and carcass yield 22- 42-d-old diets with levels below or above...

The 1875chickens were housed boxes distributed among 5 treatments 15 replicates 25 chickens each. experiment included a...

The effect of stocking density in broiler chickens (11.08 and 13.20 birds m-2), between 5 45 days age, was assessed with regard to performance, cut yield, litter moisture frequency pododermatitis injuries. Further, 476 one-day chicks Cobb 500® were distributed a completely randomized design at two densities (birds m-²), seven replications per treatment 14 experimental units. Birds housed lower (11.08) increased feed intake (p < 0.05), without any on weight gain conversion. Retail yields not...

This study evaluated the effect of different levels canola meal in diet to laying Japanese quails on productive performance, egg quality and economic viability. A total 120 80-day-old (Coturnix coturnix japonica) with average weight 146.54 ± 12 g were during 84 days. Dietary treatments consisted replacement soybean at 0, 10, 20, 30, 40 or 50%. We viability, internal external eggs. Data analyzed by polynomial regression 5%. Body decreased linearly as level increased (p = 0.0055). Egg 0.0032)...

O estudo do comportamento ingestivo é uma ferramenta importante para a avaliação de dietas e da relação animal com o sistema criação. Objetivou-se este analisar bovinos nos sistemas pastejo confinado algumas variáveis em condições experimentais. Utilizando metodologia revisão sistemática, foram analisados trabalhos científicos publicados no período setembro 2004 março 2018, totalizando inicialmente 88 artigos após aplicação critérios seleção, 35 constituíram banco informações, 153...

A trial was conducted to evaluate the use of dehulled and unpolished whole rice in Japanese quails’ diet. total 100 80-days-old quails (149.07 ± 10 g) were distributed five treatments: 0% (control diet based on corn soybean meal), 20, 40, 60, 80% replacement corn; respectively, treatments 1, 2, 3, 4, 5. Productive performance evaluated through egg production (%), weight (g), body mass feed conversion per dozen eggs. The following variables measured internal quality eggs: albumen height (mm),...

Whole rice bran (WRB) was added to Japanese quail feed, and the effects of stabilization WRB with organic acids its storage for different amounts time were evaluated respect performance egg quality, centesimal composition, sensory characteristics. We used 150 90-d-old quails. had a 5 × 2 factorial scheme five periods (0, 30, 60, 90, 120 d), without acid treatment. To replace corn, 20% diet. Feed consumption increased up 71 d (P = 0.01) then subsequently decreased. An increasing quadratic...

Abstract This study aimed to verify the relationship between parameters of physicochemical composition, microbiological quality, and volume milk delivered a dairy in northern region Rio Grande do Sul, Brazil, at four different times 2020. For this purpose, volume, protein, fat, lactose, total solids, somatic cell count (SCC), standard plate (SPC) were evaluated. The data collected January, April, July, October from 1634 farms located Sul. evaluated using Pearson’s correlation, while means...

The objective of this study was to evaluate different strategies for the oxidative stabilization rice bran (RB) in diet broiler chickens using natural antioxidant additives, synthetic additives and heat treatment on performance, breast meat quality liver fat content nutrient digestibility coefficients. Furthermore, aimed effects antioxidants, additive treatments, without natural, synthetic, three heat, dry-heat moist-heat, after stored 90 days then incorporated into experimental diets. 1080...

The effects of diet supplementation with ?-tocopherol acetate (VE) and selenium yeast (SeL) on the water holding capacity (WHC), cooking weight loss (CL), drip (DL), pH, colour concentration breast chickens fed diets based corn or brown rice were studied. From 21 days age, a total 200 birds housed in 38 floor pens (experimental unit) randomised 23 factorial arrangement. levels VE (0 mg/kg), organic 0.3 ppm) two (100% 100% rice) eight treatments: T1) + 0 SeL (control); T2) mg/kg SeL; T3) ppm...
