ABSTRACT The objective was to evaluate the intake, digestibility, nitrogen balance, and metabolic profile of lactating goats fed diets containing detoxified castor cake (DCC) by alkaline solutions during 150 days of lactation. Twenty-four Saanen and Anglo Nubian goats, approximately 17 months old (first lactation) and body weights of 43±2.97 kg, were distributed in a completely randomized block design with eight replicates. Treatments consisted of three diets, one containing soybean meal (SM) and two others containing DCC, with calcium hydroxide [Ca(OH)2] […]

ABSTRACT In the present study, we aimed to assess the toxicity of artemisinin on the haematological system and its effect on the productive performance of broiler chickens. Eighteen-day-old chickens were randomly divided into four groups of 30 chickens (three replicates of 10 broilers/group): control group and three experimental groups: ART5 – diet with 5 ppm of artemisinin; ART50 – diet with 50 ppm of artemisinin; and ART500 – diet with 500 ppm of artemisinin. Artemisinin enhanced the productive performances of […]

This work evaluated the herbicides selectivity acetolactate synthase inhibitors and photosynthetic II applied in post- emergency in palisadegrass (Brachiaria brizantha cv. Marandu) and signalgrass (Brachiaria decumbens cv. Basilisk) plants in field conditions and their effect in seed quality. Treatments tested in g ha-1 were: imazethapyr at 100, chlorimuron-ethyl at 15, nicosulfuron at 50, bentazon at 720, atrazine at 3.000, and control plot. Two field trials were set up on complete randomized block design with four replicates; laboratory studies were carried […]

Sixteen Santa Inês sheep were randomly allotted to four treatments (T0 = 81% tifton hay (TH) and 19% concentrate (soybean meal and corn); T27 = 27% egeria hay (EH), 54% TH and 19% concentrate; T81 = 81% EH and 19% concentrate) to evaluate the effect of Egeria hay inclusion in the diet on voluntary intake, weight gain and feed efficiency. Voluntary intake reduced and body weight gain was not affected by EH inclusion. During the experimental period, weight gain was […]
