ABSTRACT The consumption of saline water in semiarid regions is a recurrent situation that can affect the ingestive behavior of small ruminants. This study evaluated the ingestive behavior of Santa Inês sheep maintained in a climatic chamber under two air temperatures -25 °C within the thermal comfort zone (TCZ) and 32 °C above the TCZ - and consuming water with three levels of salinity - 2.0, 4.0, and 8.0 dS m-1. The experimental design was completely randomized in 2 × 3 factorial schemes, comprising two air temperatures and drinking water with three levels of salinity, in six replicates (animals). Regardless of air temperature, the consumption of saline water did not affect feed and water intake by the sheep; however, there was a decrease in feed intake...

The aim of this study was to evaluate the effect of sire breed on performance and feed efficiency in feedlot of crossbred cattle. Steers (n=74) and heifers (n=71) produced along two years by breeding Nellore, ½ Nellore x ½ Angus and ½ Nellore x ½ Caracu cows with Braford (BF), Charbray (CC) and Caracu (CR) sires were raised grazing tropical grasses until 20 months (mo) of age and then finished in feedlot for 4 mo. Animals were kept in individual pens allowing measuring of daily dry matter intake (DMI) during finishing phase in feedlot. Weight records were taken in the beginning (BBW) and in the end (EBW) of the feedlot as well as every 28 days to calculate average daily gain (ADG). Feed conversion rate (FCR) was used as a measure of feed efficiency. Data...

Improvement of feed intake through supplementation with an attractant mix in European seabass fed plant-protein rich diets
Provedor de dados: 5
Autores: Dias, Jorge; Gomes, Ef; Kaushi, Sj.
The incorporation of an attractant mixture by substitution of an equivalent amount of basal dietary mixture was studied in terms of feed intake and growth performance in European seabass juveniles (mean initial weight : 17 g) fed plant-protein rich diets during 21 days. Three diets had as main protein sources; fish meal, or one of two soy protein concentrates (S and E). To the basal mixture of these last two diets, as well as to a corn-gluten based diet, an attractant amino acid mixture was added at a 2.5% level. Daily feed intake was measured throughout the experimental period. Feed intake and weight gain were highest in seabass fed the fish meal based diet. In those fed the soy protein concentrate diets, the addition of the attractant mixture improved...

The Effects of Feed Restriction and Isolated or Group Rearing on the Measurement of Individual Feed Intake and Estimation of Feed Conversion Ratio in Juvenile Nile Tilapia (Oreochromis niloticus) for Selective Breeding Purposes
Provedor de dados: 5
Autores: Rodde, Charles; Vandeputte, Marc; Quoc Trinh, Trong; Douchet, Vincent; Canonne, Marc; Benzie, John A. H.; De Verdal, Hugues.
Accurately measuring the phenotype at the individual level is critical to the success of selective breeding programs. Feed efficiency is a key sustainability trait and is typically approached through feed conversion ratio (FCR). This requires measurements of body weight gain (BWG) and feed intake (FI), the latter being technically challenging in fish. We assessed two of the principal methods for measuring feed intake in fish over consecutive days: (1) group rearing 10 fish per group and video recording the meals and (2) rearing fish individually on a restricted ration. Juvenile Nile tilapia (Oreochromis niloticus) from the Genetically Improved Farmed Tilapia (GIFT) strain and the Cirad strain were entered into the study (128 GIFT and 109 Cirad). The GIFT...

Evaluation of behavioral changes induced by a first step of domestication or selection for growth in the European sea bass (Dicentrarchus labrax): A self-feeding approach under repeated acute stress
Provedor de dados: 5
Autores: Millot, Sandie; Pean, Samuel; Leguay, Didier; Vergnet, Alain; Chatain, Beatrice; Begout, Marie-laure.
Among other strategies to improve fish welfare in rearing environment, domestication and/or selective breeding was proposed to minimize fish responsiveness to husbandry practices. To verify this hypothesis on a recently domesticated specie, the sea bass, Dicentrarchus labrax, L., an experiment was realized, using four populations differing according to their level of domestication or selection: one population produced from wild parents (Wild), one population produced from parents domesticated for one generation (Domesticated) and two produced from parents selected for growth for one generation (Selected A and Selected B). The experiment was carried out over 91 days with 600 fish (50 fish per tank, 150 fish per population). After a control period, the fish...

Improving feed efficiency in fish using selective breeding: a review
Provedor de dados: 5
Autores: De Verdal, Hugues; Komen, Hans; Quillet, Edwige; Chatain, Beatrice; Allal, Francois; Benzie, John A. H.; Vandeputte, Marc.
Improving feed efficiency (FE) is key to reducing production costs in aquaculture and to achieving sustainability for the aquaculture industry. Feed costs account for 30–70% of total production costs in aquaculture; much work has been done on nutritional and husbandry approaches to improve FE but only a limited amount of research has been devoted to using genetics, despite its potential. This paper reviews past work to improve FE in fish using selective breeding and assess future directions. Direct selection on FE traits requires methods to measure individual feed consumption and estimate FE efficiently and accurately. This is particularly difficult to do in fish because of the environment in which they live. Many of the published studies on FE were found...

Regulation of feed intake, growth, nutrient and energy utilisation in European sea bass (Dicentrarchus labrax) fed high fat diets
Provedor de dados: 5
Autores: Boujard, Thierry; Gelineau, Anne; Coves, Denis; Corraze, Genevieve; Dutto, Gilbert; Gasset, Eric; Kaushik, Sadasivam.
Three practical isoproteic (54% protein) diets were formulated to contain graded levels of crude fat (diet L: 10%, diet M: 20% and diet H: 30%). Each diet was assigned unrestrictedly to three and restrictedly to two replicate groups of fish (IBW 243 g). In unrestricted groups, increasing the dietary lipid level led to a significant decrease in voluntary feed intake without affecting growth rate. In the feed-restricted groups, daily growth rates increased with increasing dietary fat levels. There was a significant and inverse effect of the dietary fat content on whole body moisture and fat levels, with highest lipid (ca. 20%) and lowest moisture (ca. 58%) contents in sea bass fed diet containing the highest lipid level; muscle lipid concentration was...

The combined effects of feeding time and dietary fat levels on feed intake, growth and body composition in rainbow trout
Provedor de dados: 5
Autores: Gelineau, Anne; Bolliet, Valérie; Corrraze, Geneviève; Boujard, Thierry.
The combined effects of feeding time (morning and evening) and dietary fat concentration on feed intake, growth, body composition and lipid tissue distribution were examined in rainbow trout fed on demand. To that purpose, diets with low (LE, 6% lipid) or high energy concentrations (HE, 24% lipid) were used in four treatments that combined provision of the same (HE-HE or LE-LE) or different (HE-LE, LE-HE) diets at morning and evening meals. Digestible energy intakes of the LE-HE (229 U kg(-1) d(-1)) and HE-HE (269 U kg(-1) d(-1)) groups were significantly different. There was no significant difference in the amount of energy intake between the two meals of the day in any of the treatments. The main effect of dietary treatment was on lipid intake; fish in...

Abstract: The objective of this work was to evaluate the performance of crossbred steers post-weaned in an integrated crop-livestock system (ICL) and finished in a feedlot, fed either a high-level concentrate diet or whole corn with no roughage. Weaned calves of two breed groups - ½ Angus × ½ Nellore, and ½ Charolais × ¼ Angus × ¼ Nellore - were allotted in a completely randomized experimental design (CRD). During the rainy season, the ½ Angus × ½ Nellore animals showed a higher performance than the ½ Charolais × ¼ Angus ×¼ Nellore ones, with 0.748 and 0.490 kg average daily gain, respectively. The productivity in the post-weaning period was 926 kg ha-1 body weight in a 11-month period, in the ICL system. Subsequently, the animals were confined and fed...

Provedor de dados: 89
Autores: Assuena,V; Junqueira,OM; Duarte,KF; Laurentiz,AC; Filardi,RS; Sgavioli,S.
This experiment was carried out to evaluate the effects of the inclusion of different levels of phytase on broiler performance, bone densitometry, and phosphorus and nitrogen excretion. Nine hundred and sixty one-day old broilers, 50% males and 50% females, were distributed in a completely randomized experimental design into five treatments and six replicates 32 birds each. The treatments consisted of a control diet and four diets with the addition 25, 50, 75, and 100 g/ ton of phytase (250, 500, 750 and 1000 FTU of phytase/kg fed). Diets were formulated to contain equal nutritional levels, and considered the phytase product nutritional levels. In general, the addition of phytase resulted in a linear decrease in broiler performance. However, the...

Provedor de dados: 89
Autores: Avellaneda,Y; Ariza-Nieto,C; Afanador-Téllez,G.
ABSTRACT A total of 320 13-weeks-old pullets were weighed and randomly allocated to treatments comprised by four levels of crude glycerin (0, 3, 6 or 9%) and two levels of ME (metabolizable energy, difference of 100 kcal/kg) in the diets growing (14 to 17 weeks of age), pre-lay and pre-peak (low: 2750, 2800 and 2750 kcal/kg and high: 2850, 2900 and 2850 kcal/kg, respectively). During the study, body weight was registered until 30 weeks of age, feed intake, egg weight and egg-production for each repetition and for individual hens were measured every week. The information was analyzed through a completely randomized design with a 4x2 factorial arrangement. During the growing phase, hens that received low energy diets consumed more feed (p&lt;0.05), gained...

Live Performance, Carcass, and Bone Quality Responses of Grower and Finisher Broilers to Dietary Metabolizable Energy Levels
Provedor de dados: 89
Autores: Gopinger,E; Krabbe,EL; Surek,D; Lopes,LS; Avila,VS.
ABSTRACT Broiler energy nutrition has attracted attention due to its economic importance, particularly during the rearing period of 22-42 days of age. There are many evidences that broilers changed their feed intake capacity due to genetic selection, especially when good quality pellets are fed, which suggests that modern broiler strains may achieve good performance when fed low metabolizable energy levels. The objective was to evaluate the energy efficiency, performance parameters, bone parameters, and carcass yield of 22- to 42-d-old broilers fed diets with energy levels below or above their requirements, while maintaining the density of all other nutrients. In total, 900 male broilers were distributed in a randomized block design, with five treatments...

Autores: Itza-Ortiz,MF; Peraza-Mercado,G; Castillo-Castillo,Y; Rodriguez-Alarcon,CA; Vital-Garcia,C; Jaramillo-Lopez,E; Carrera-Chavez,JM.
ABSTRACT Poultry farmers in the southeastern of Mexico consider that the productivity of the hens that comes from rearing on floor has a higher productive performance than reared hens in cages, mainly due to higher percentage of egg laying and lower mortality. The aim of this study was to evaluate the productive performance of the laying hen in relation to the type of rearing. A total of 79680 pullets Bovans White of 17 weeks of age were housed in cages with five pullets cage-1 (405 cm2pullet-1). They were divided in two treatments according to their type of rearing (floor vs cage) with four replicates. The study period was from week 20 to week 40 of age. The variables evaluated were daily (%) and cumulative mortality (%), egg production (%), egg weight...

Effects of dietary valine:lysine ratios on lactation performance of primiparous sows nursing large litters
Provedor de dados: 96
Autores: Devi,Subramaniam Mohana; Park,Jae Won; Kim,In Ho.
ABSTRACT Eighteen sows were used to determine the effect of dietary valine:lysine (val:lys) ratios on lactation performance in primiparous sows and litter performance. Sows, raised in individual pens, were randomly assigned to 1 of 2 experimental diets containing different standardized ileal digestibility (SID) val:lys ratios of 0.80 or 0.85. Corn-soybean-wheat-based diets were formulated to achieve the dietary treatments (0.86% or 0.87% SID lysine, and 0.69% or 0.74% SID valine). All diets were formulated to have 3,450 kcal metabolizable energy/kg. The experiment lasted 24 d. At the end of the experiment, body weight loss, backfat loss, average daily feed intake, and days to return to estrus were not affected by the different dietary val:lys ratios....

ABSTRACT - The objective of this study was to evaluate the effect of replacing wheat bran by spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on intake and nutrient digestibility and ruminal parameters of sheep. Five sheep (Santa Inês; average initial weight of 34.0±3.6 kg) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. The maximum dry matter (DM; 1414 g d−1), digestible organic matter (658 g d−1), and neutral detergent fiber corrected for ash and protein (NDFap; 425 g d−1) intakes were estimated by replacing 80.2, 89.9, and 50.5% of wheat bran. Dry matter and crude protein digestibility increased by 0.60 and 0.85 g kg-1 of DM. With the replacement of 57.1 and 62.2% of wheat bran, a maximum rate...

The study was carried out to develop and to evaluate new equations to predict dry matter intake (DMI) of Nellore and Zebu-crosses cattle using meta-analysis procedure. The data used to estimate the parameters were collected from independent performance experiments using growing and fattening Nellore and Zebu-crosses cattle, and they were compiled from 561 experimental units. Before proposing an equation to predict DMI, it was observed that the genetic group was a source of statisticaly significant variation. Therefore, equations to predict dry matter intake in the Zebu-Crosses and Nellore cattle were independently developed. The regression equations for Zebu-crosses cattle were: DMI = -2.6098 + 0.08844BW0.75 + 4.4672ADG - 1.3579ADG2 and DMI = -1.0094 +...

Autores: Ribeiro,Felipe de Azevedo Silva; Vasquez,Leonardo Avendaño; Fernandes,João Batista Kochenborger; Sakomura,Nilva Kazue.
The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare). A randomized block design in a factorial scheme (3 × 2) with three feeding levels (30, 60 and 90 g/kg of body weight (BW)/day) and two feeding frequencies (1x and 2x/day) was set up in duplicate, representing 24 experimental units. Data were analyzed using two-way ANOVA and the Tukey test for comparison between means. After 84 days, results indicated that both factors influenced fish performance. No interaction between these factors was, however, observed. Increased feeding level and feeding frequency resulted in increased feed intake. The feed conversion ratio was negatively affected by feeding level,...

ABSTRACT This experiment was conducted to evaluate the growth performance and carcass characteristics of gilts from 25 to 100 kg body weight (BW) fed diets with increased net energy (NE) levels. Seventy-two gilts with initial BW of 23.24±2.47 kg were allotted to one of six dietary treatments (2300, 2380, 2460, 2540, 2620, and 2700 kcal NE kg−1) using a completely randomized block design, with two pigs per replicate, and six replicates per treatment. Corn-soybean meal-based diets were formulated to be fed in three phases (25 to 50, 50 to 70, and 70 to 100 kg BW). Soybean oil was added to replace the inert ingredient kaolin to meet the NE level of each diet. Increasing dietary NE decreased the average daily feed intake (ADFI) and improved the feed:gain ratio...

Alkanes as markers in nutritional studies with wild ruminant and non-ruminant animals
Provedor de dados: 63
Autores: Oliveira,Dimas Estrasulas de; Silva,Sila Carneiro da.
Knowledge of information relative to the digestibility, intake and botanical and morphological composition of the diet is important in nutritional studies, since it provides the basis for understanding aspects related to the ingestive behavior and selectivity of animals. N-alkanes have been used successfully as markers in studies with many species of animals, particularly domesticated ruminants, most of the times as replacements for conventional markers as chromium oxide for example. However, for wild ruminants and non-ruminant animals information on this technique is still scarce and, as a consequence, its potential for use unknown. This review reports the use of this technique in studies of feed digestibility, intake and diet composition with wild...

 The purpose of this study was to evaluate the effect of interaction between increasing neutral detergent fiber content and particle sizes on ingestive behavior of dairy goats. Forty-eight lactating, multiparous Saanen and Alpine goats, with average milk production of 1.4 ±0.57 kg d-1, around 60th ±12 day of lactation were distributed in a 3 x 4 factorial completely randomized design. The diets consisted: three particles sizes (02, 05 or 15 cm) and four levels of neutral detergent fiber (34, 41, 49 or 57% NDFf) from forage (Tifton 85 hay). The ingestive behavior was monitored during 24 hours. A regression and a multivariate time series cluster analysis were performed. No interaction was found (p &gt; 0.05) between treatments. Feeding time was different...

The effect of partial and total substitution of soybean meal crude protein (SBM) by canola meal (CM) on live weight (LW), daily weight gain (DWG), daily feed intake (DFI) and feed conversion (FC) in female rabbits are provided. Rabbits were evaluated from weaning period (43 days of age) to adult life when they are capable of reproduction (150 days of age). Forty-eight White New Zealand females were used and distributed in four treatments. SBM was substituted at 00%, 33%, 66% and 100% levels by CM. The partial or total substitution of SBM by CM did not change (P &gt; 0.05) the LW after 70 days old. Dunnett’s test showed that, independently of substitution level, FC of animals fed on meal with 33% SBM substitution by CM from age 43 to 90 days and 43 to 150...

Abstract In order to evaluate the effect of rosemary oil and micro mineral sources on the performance and egg quality of laying hens, 288 hens were used and distributed in a completely randomized design using a 2x3 factorial (mineral sources x rosemary oil) with six different diets and six replications. Diets were formulated containing inorganic or organic minerals, with or without added rosemary oil (100 and 200 mg kg-1). The treatments showed interaction for average egg weight, yolk color, albumen and yolk percentage, with significant results from the use of organic minerals compared to inorganic minerals. The addition of 200 mg kg-1 rosemary oil in diets improved laying rate, egg mass, specific gravity, number of pores on the shell when compared to...

Provedor de dados: 52
Autores: Santos,José Maurício Gonçalves dos; Moreira,Ivan; Martins,Elias Nunes.
The requirements of lactating sows for total lysine and metabolyzable energy (ME) to support subsequent reproduction performance were evaluated. One hundred and twenty sows were used. The treatments were constituted of eight diets (factorial arrangement of four levels of total lysine: 0.75, 0.90, 1.05 and 1.20%, and two levels of ME: 3,250 and 3,400 kcal ME/kg). There was interaction between lysine and ME on the plasma urea nitrogen (PUN), with linear decrease effect on level of 3,250 kcal ME/kg, and quadratic effect on level of 3,400 kcal ME/kg, with the lowest level of PUN with 1.06% lysine. The reproductive performance in the subsequent farrowing was not affected by the lysine levels and ME, hence, neither the total born nor the born alive differed...

Autores: Maiorka,Alex; Dahlke,Fabiano; Santin,Elizabeth; Bruno,Luis Daniel Giusti; Macari,Marcos.
The feed intake and performance of the broilers fed with different levels of dietary energy in the starter diet to 21 days of age were evaluated. In Experiment 1 it was evaluated the performance of birds fed to 2,900 and 3,200kcal ME kg-1 diets, and the results show that ME intake was highest for birds 3,200kcal ME kg-1 on the 7th day of age. Feed intake (FI), weight gain (WG), and feed conversion (FC) were not affected by dietary energy level on the 7th and 14th day of age, but on the 21st day of age, WG and FC were better for 3,200kcal ME kg-1 diets. In the experiment 2, isocaloric diets (2,900kcal ME kg-1) were formulated with four different oil levels (0, 1, 2, and 3%), in order to observe diet preference. Between 6 and 10 days of age, a quadratic...

The optimal dietary digestible protein to energy ratio is critical for the success of fish farming. Considering that it provides the proper development of the animals, this study was undertaken to evaluate the effects of different dietary digestible protein to energy ratio in diets for goldfish fingerlings. Diets were formulated to contain 28.0, 35.0, 42.0 and 49.0% DP and 3,600 and 3,200 kcal/kg. The growth parameters evaluated were daily weight gain (DWG), feed intake (FI), feed conversion ratio (FCR), protein efficiency ratio (PER), protein productive value (PPV) and energy retention ratio (ERR) and specific growth rate (SGR). Regardless FI, all the parameters were affected by protein and energy levels and interaction between both factors was observed....
