Thirty six 7/8 Ile de France 1/8 Polwarth (18 males and 18 females) lambs averaging 17.90 ± 1.27 kg of body weigh (BW) were randomly assigned to one of the following three diets: 1) control diet; 2) SRPAD – 8% freshwater fish (Oreochromis niloticus) residue silage; or 3) SRPAM – 8% sea fish (Lophius gastrophisus) residue silage. The fish residue silages partially replaced soybean meal in the diet; corn silage (40% DM basis) was used as the sole forage source. […]

This experiment was conducted to evaluate the effect of inclusion of cashew nut meal (CNM) in diets on nutrient digestibility, bird performance and egg characteristics of Japanese quails. A total of 270 japanese quails with 17 weeks of age were weighed and distributed into a completely randomized design with six diets and nine replicates of five birds in each experimental unit. Treatments consisted of one diet without CNM (control) and five diets containing 4; 8; 12; 16 and 20% of […]

The objective of this experiment was to study the development of external body components and that of discarded fat in feedlot finished crossbred cows from the second (G2 – 3/4Charolais (C) 1/4Nellore (N) and 3/4NC) and third (G3 – 5/8CN and 5/8NC) generations of a Charolais ´ Nellore rotational crossbreeding program slaughtered with 465 (T465), 507 (T507) and 566 kg (T566) of body weight. At the beginning of the trial, age, body weight and body condition score averaged, respectively, 8.5 […]

This trial was conducted to evaluate the sugar cane silage treated with chemical additive (urea-1.5%, sodium benzoate-0.1%, and sodium hydroxide-1.0%), associated with control, and two bacterial inoculants (Propionibacterium acidipropionici + Lactobacillus plantarum e Lactobacillus buchneri), in a factorial scheme (4 x 3), and three replications per treatment. It was evaluated the nutritive value of the sugar cane treated with different additive combinations, before and after ensilage. The association of the P. acidipropionici or L. buchneri with NaOH, compared to the […]

With the objective to evaluate the inclusion of spray dry blood plasma in diets for piglets weaned at 21 days of age (5.9 ± 0.40 kg initial BW), a total of 112 animals were allotted to completely randomize block design with four treatment and seven replications with four animals per experimental unit, in three subsequent periods: from 21 to 28 days (period 1), from 29 to 35days (period 2), from 36 to 42 days (period 3). The piglets were maintained […]

The objective of this trial was to compare and determine the most adequate time interval to register chewing activity in Santa Inês sheep. The following time intervals were investigated: 5, 10, 15, 20, 25, and 30 minutes. Eighteen intact male sheep averaging 22.62 kg of body weight at the beginning of the study were used. Animals were housed in individual pens and randomly assigned to one of six treatments: ammonia-treated elephantgrass or elephatgrass supplemented with three concentrates sources (0% cocoa […]

The objective of this research was to evaluate the effects of fat supplementations as calcium salts of palm oil (PF), whole rice bran + rice oil (WRBO) and whole rice bran + bovine tallow (WRBT) on dry matter intake, productive efficiency and energy balance of dairy cows in the beginning of the first third period of lactation. Control diet contained 2.9% EE, while the diets GP, FAIO and FAIS contained 5.13; 5.29 and 5.16% EE, respectively. Pure bred Jersey cows […]

The effect of the substitution of an antibiotic by different levels of spent mushroom substrate (SMS) of Agaricus blazei on the performance of broiler chicks from 1 to 42 days old was evaluated. Seven diets were evaluated, six with SMS addiction (0.0, 0.2, 0.4, 0.6, 0.8, and 1.0%) and one with antibiotic (avilamycin 10 ppm). A total of 588 one day old chicks was allotted to a complete randomized design, with six replications per diet (three per sex) and 14 […]

The influence of feeding frequency was evaluated on weight gain, specific growth rate, feed conversion and survival of jundiá juveniles. Twelve groups of 280 fish (7.47 ± 1.73 g) were each stocked in twelve ponds (2 fish/m2) and fed to apparent satiety an extruded commercial feed containing 42% CP In four feeding schedules: 1, 2, 3 and 4 times a day, in triplicate, for 120 days (May to September, 2003). Average weight gain was recorded by sampling 10% of the […]

The objective of this study was to estimate heritability and genetic correlations for body weight at birth (BW), weaning (WW), twelve (W12) and eighteen (W18) months of age, weight gains from birth to weaning (DGBW) and from birth to eighteen months of age (DGB18), days to 175 kg from birth to weaning (D175 = 175/DGBW), days to 450 kg from birth to slaughter (D450 = 450/DGB18) and female mature body weight (ABW) using data from a herd of Canchim (5/8 […]
