This paper describes two experiments testing the effects of rations containing different sunflower meal (SFM) levels on laying hens’ performance and egg quality. In the first experiment a total of 240 animals were divided in groups (n = 6) of 10 hens each, balanced by age and live weight and at random allocated to four isocaloric rations with 0, 7, 14 and 21% of SFM. There was no effect (P> 0.05) of SFM leve...
Two experiments evaluated the pure glycerin in broiler chicken diets. Experiment 1 was a metabolism test using total feces sampling method with 96 male chickens aging from 17 to 25 d when animals were fed on two treatments: diet1 = no glycerin and diet2 = 60g/kg of glycerin. The apparent metabolized energy measured 4015 kcal/kg and the apparent metabolized corrected for nitrogen balance was 3911 kcal/kg. Experi...
The aim of this study was to evaluate the effect of lineage, battery cage space allowance and tryptophan level in diet on commercial laying hens performance. A total of 720 hens from two different lineages and 31-47 weeks of age were used in a 2x3x4 factorial experimental design (lineages A and B; space allowances of 563, 450 and 375 cm2/animal and tryptophan levels of 0,175%; 0,195%; 0,392% e 0,591%), with twe...
Two experiments were carried out to evaluate the use of sunflower cake in the rations to gestating and lactating sows. Forty eight sows, 24 gestating and 24 lactating, with the same genetic background were used. The treatments were represented by the levels of sunflower cake included in the rations of gestating and lactating sows, been: 0.0; 5.0; 10.0; 15.0%. The experimental design for both experiments was a r...
Four adult horses were used in a trial in latin square design (4 X 4). The treatments were: AH - alfafa hay (Medicago sativa L.), CH - coastcross hay (C. dactylon Pers) and EH - stargrass hay (Cynodon. nenfluensis L.). The experiment lasted 65 days, devided as following: a 5-day pre-experimental period, and 4 experimental periods of 15 days (10 days adaptation and 5 days total feces collection). The analysis of...
Two experiments (a digestibility and a performance tests) were carried out to evaluate sunflower seed (SS) as swine feeding on growing and finishing phases. To performance evaluation 48 pigs, with 19.78 kg liveweight were allotted to four treatments (diet without SS, 5%, 10% and diet with 20% of SS) and they were evaluated during four periods (growing I and II, finishing and total period). All animals were slau...
The aim of this work was to study the effects of Soya bean oil and toasted whole Soya bean on performance of meat chicken. A completely randomized design experiment using 924 one day old pullets (cobb) was carried out. Male and female animals were separately divided in 28 groups of 33 pullets each, allocated in boxes and fed with seven different ration types as follow: R1- maize, Soya bean meal and Soya oil; R2...
The experiment was carried out at Universidade Estadual de Londrina, Paraná, with the objective of evaluating the effects of the utilization of raw pigeon pea ground (RPPG) variety IAPAR 43-Aratã, in the ration, on the productive indirect index of broilers at period 1 (1-28 days) and its influence on the period 2(29-45 days) and also on the total period (TP= 1-45 days). 270 chicks of Arbor Acres line were used,...
