Morphometric Evaluation

The residual from the food industry has the potential to replace the traditional ingredients used in animal feed, and the dry brewery residue (DBR) may be an alternative for this purpose. This study aimed to evaluate the use of DBR in the diets of broiler from 22 to 42 days of age. Five hundred and forty-six male broilers were used, with an initial average weight of 865 ± 8 g. The animals were distributed in a completely randomized design, with six levels of DBR inclusion (0, 2, 4, 6, 8, 10%), seven replicates and thirteen animals per experimental unit (EU). Weight gain (WG), average feed intake (AFI) and feed:gain ratio were evaluated. At 42 days of age, blood samples were collected from two broilers of each EU, and one broiler per EU was slaughtered to investigate the intestinal development. DBR interposed the WG and promoted a linear effect in this variable from 22 to 42 days of age. This effect was not observed for AFI. The inclusion of DBR interfered with the serum cholesterol values, showing a quadratic influence at the maximum response for the inclusion of 4.96%. However, the blood parameters of triglycerides, uric acid, creatinine, aspartate aminotransferase, alanine aminotransferase and total protein remained unchanged, regardless of the level of dietary DBR. No changes in villus height and crypt depth were observed by intestinal morphometric evaluation. The inclusion of 10% DBR can be used in a poultry diet, without any damage to the performance, metabolism and development of the broilers.

The study aimed to examine the effect of using pollard in rations on the growth of proventricular, ventricular, duodenal, jejunal and ileal organs in 7-week-old broiler chickens. The research material used 200 broiler chickens aged 7 weeks with an average weight of 859 ± 59 g with each experimental unit consisting of 8 - 9 tails. The design used was a completely randomized design with 5 treatments and 3 replications. Treatment is given (T0 = Comersial feeds, T1 = Feed with pollard without processing, T2 = Feed with pollard treated physically, T3 = Feed with pollard treated physically and biologically, and T4 = Feed with pollard treated physically and biology 60%) and 3 replications. Based on the results of the study it can be concluded that the administration of pollard treated physically and biologically has not been able to increase all the relative weights of the digestive organs of broiler chickens aged 7 weeks. In the proventriculus organ, the treatment can increase the relative weight of broiler digestive organs, but the relative weight of the proventriculus produced is still relatively normal. Measurement of broiler chicken organ weight needs to be done per week to determine the rate of increase in the relative weight of the optimal digestive organs, so that the maximum data on the growth of broiler organs are obtained optimally

This study aims to determine the interaction between cage density with dietary restrictions on ration consumption, growth, feed conversion, carcass percentage, abdominal fat, heterophile-lymphocyte ratio and broiler chicken's Income Over Feed Cost. The research lasted for 2 months in the Cage of  Broiler Chicken Farm SMK Negeri I Nabire. The research material used was 135 DOC unsex Cobb strain (CP 707) with an average weight of 42.5 grams / head; commercial feed starter BR1 CP 511 B and finisher BR2 CP 512 B and 27 units of battery cages. The experimental design used was a completely randomized design factorial pattern (3 x 3). Factor I is enclosure density with 3 levels, namely K1 (3 animals / 0.5 m2), K2 (5 animals / 0.5 m2) and K3 (7 animals / 0.5 m2) and Factor II is restriction on ration with 3 levels namely R1 (100% according to ad libitum requirements), R2 (85%) and R3 (70%) given at 4-5 weeks of age. Each treatment combination was repeated 3 times to obtain 27 experimental unit units. The results showed there was no interaction between cage density factors with dietary limitation factors for all observational variables. But the cage density factor, significantly (P <0.05) shows that the denser the cage the lower the consumption of rations and the percentage of abdominal fat in broilers. Whereas the restriction factor of the ration, significantly (P <0.05) indicates that the higher the percentage of restriction ration the lower the ration consumed and the higher Income Over Feed Cost (the greater the business income of broiler chickens obtained) despite the indication of stress in broilers with a high average heterophyll-lymphocyte (H / L) ratio of  2.44.

This study aimed to evaluate the effects of feeding plans with or without addition of glycerin, in different ages, on performance, carcass yield, litter moisture and footpad lesions of broiler chickens. 540 male Cobb broilers were utilized, distributed in a completely randomized design with six treatments (treatments consisted of the inclusion or not of glycerin in diets at all periods or only at different stages: 1 to 7, 8 to 21, 22 to 33 and 34 to 42 days), in six replicates of 15 birds each. Diets were provided ad libitum. At 42 days, the average weight, weight gain, feed intake, feed conversion, carcass yield, litter moisture and footpad lesions were evaluated. There was no effect (p> 0.05) of dietary plans on the performance variables. The feeding plans did not influence (p>0,05) the carcass and cuts parameters at 42 days. However, there was significant effect (p <0.05) of the dietary plans on litter moisture and plantar lesions. Effects were observed (p>0,001) for the feeding plans, were the highest and the lowest incidence of lesions were present in the birds that consume diets with and without addition of glycerin, in the period from 1 to 42 days of age, respectively.

The objective was to evaluate the performance, relative organ weight, morphometry, intestinal length and pancreatic enzyme activity of broilers receiving neonatal supplementation. A total of 900 Cobb 500 broiler chicks was housed in 30 boxes of 2.5 m². The treatments were divided in a completely randomized design with six replications, and consisted of five inclusion levels (0.0, 2.5, 5.0, 7.5 and 10 grams per bird). The supplement used was based of amino acids, vitamins and minerals, which was provided on the ration on the first day in the housing. Statistical analysis was performed using SAS (2008) and when significant broken down using a polynomial regression. Due to the inclusion of the neonatal supplement in the period from one to seven and one to 21 days of age, the feed intake presented a linear effect and the weight gain, a quadratic effect. The relative weights of the gizzard and liver showed a quadratic effect, and the inclusions of 4.18 and 3.41 grams/bird provided the lowest weights, respectively. The jejunum villi height decreased with supplementation as well as the activity of pancreatic lipase. It can be concluded that neonatal supplementation benefited the performance of birds up to 21 days of age.

Abstract Piglets experience a decline in body temperature immediately after birth, and both drying and warming piglets at birth reduces this. However, these interventions may have less effective at higher farrowing room temperatures. This study was carried out at a commercial facility to compare the effect of drying and/or warming piglets at birth on postnatal rectal temperature (RT) under relatively warm farrowing room temperatures (26.6 ± 2.09°C). Forty-five sows/litters were used in a completely randomized design to compare three Intervention Treatments (applied at birth): Control (no treatment); Warming (piglets placed in a plastic box under a heat lamp for 30 min); Drying+Warming (piglets dried with desiccant and warmed as above). Temperatures in the warming boxes over the study period averaged 37.7 ± 2.75°C. At birth, piglets were weighed; RT temperature was measured at 0, 10, 20, 30, 45, 60, 120, and 1440 min after birth. Blood samples were collected at 24 h after birth from a subsample of one piglet from each birth weight quartile within each litter to measure plasma immunocrit concentration. Data were analyzed using PROC MIXED of SAS with litter as the experimental unit; and piglet a subsample of litter. The model for analysis of piglet rectal temperature included fixed effects of treatment, measurement time (repeated measure), the interaction, and the random effect of sow. Compared to the Control, piglet RT were higher (P ≤ 0.05) for the Warming treatment between 10 and 60 min, and higher (P ≤ 0.05) for the Drying+Warming treatment between 10 and 120 min after birth. Rectal temperatures were higher (P ≤ 0.05) for the Drying+Warming than the Warming treatment between 20 and 120 min. Responses to drying and/or warming were greater for low birth weight piglets (&lt; 1.0 kg) than heavier littermates, but were generally less than observed in previous experiments with similar treatments carried out under cooler temperatures. Piglet immunocrit values were lower (P ≤ 0.05) for the Drying+Warming treatment compared to the other treatments, which were similar (P &gt; 0.05). Immunocrit values tended (P = 0.10) to be lower for light (&lt; 1.0 kg) compared to heavier birth weight piglets. In conclusion, drying and warming piglets at birth was more effective for reducing piglet RT decline after birth than warming alone, though the effect was less than observed in previous studies carried out under cooler farrowing room temperatures.

This study aimed to evaluate the Texel lambs’ meat quality fed with increasing levels of crude glycerin (0, 7, 14, and 21% of dry matter) in the diet. Thirthy-two-two non-castrated male Texel lambs were used, with initial weight of 15.9 ± 4.1 kg, using a completely randomized design with four treatments and eight repetitions, per treatment. Upon reaching the average weight of 35 kg, the animals were slaughtered. The meat chemical composition was similar among treatments (P>0.05) and total lipids and crude protein presented averages of 3.47 and 20.05 g 100g -1, respectively. No changes in pH, marbling, color, and water loss under pressure were observed. The shear force did not change among treatments and the texture can be considered soft, with average values of 5.48 kgf. There was a linear (P0.05) were observed for the attributes flavor, tenderness, juiciness, and overall acceptance among treatments. Fatty acids in higher proportions in the meat lamb were to C18:1n-9 (1298.90 mg 100g-1), C16:0 (709.07 mg 100g-1) and C18:0 (433.30 mg 100g-1), with percentages of 42.72, 23.07 and 14.35%, respectively. Significant difference according to the glycerin level in the diet was observed only for the margaric acid (C17:0) with an increasing linear effect, reaching 58.95 mg 100g-1 muscle to the group with 21% crude glycerin, corresponding to 1.77% of total fatty acids. The other fatty acids did not change, and provided a satisfactory result for conjugated linoleic acid (CLA), totaling about 6.1 mg 100 g-1 muscle, corresponding to 0.21% of total lipids. The use of glycerin in the diet for finishing lambs does not alter the characteristics of the meat, maintaining the product quality for consumption.

This study aimed to assess the potential use of increasing levels of murumuru cake (Astrocaryum murumuru var. murumuru, M art.) (MC) in sheep diets as a replacement for Mombasa grass (Panicum maximum Jacq). Metabolic tests were performed with 20 castrated male sheep at Embrapa Amazônia Oriental, Belém, Pará, during 26 days. The experiment was arranged in a completely randomized design, with five diets and four replications. MC0: 100% grass; MC10: 10% MC and 90% grass; MC20: 20% MC and 80% grass; MC40: 40% MC and 60% grass; and MC60: 60% MC and 40% grass. The intake and the coefficient of apparent digestibility of dry matter (DMI and CDDM), organic matter (OMI and CDOM), crude protein (CPI and CDCP), neutral detergent fiber (NDFI and CDNDF), acid detergent fiber (ADFI and CDADF), ether extract (EEI and CDEE), cellulose (CELI and CDCEL), hemicellulose (HEMI and CDHEM), and nitrogen balance (NB) of experimental diets were determined. The intake of mineral material (MMI) and lignin (LIGI) were also determined. The DMI, OMI, MMI, CPI, NDFI, and ADFI displayed a decreasing linear effect with the replacement of Mombasa grass by MC in the diet. The EEI and the LIGI presented quadratic effects according to the replacement levels of MC in the diet. The CDDM, CDOM, and CDHEM displayed increasing linear effects, between MC0 and MC60. The CDEE, CDNDF, CDADF, and CDCEL displayed a quadratic effect, with optimum replacement levels of 56.65%, 41%, 31.33%, and 27.46%, respectively. The nitrogen balance presented a negative linear effect in the range of 0% to 60% of murumuru cake. One can conclude that murumuru cake is an alternative to the dietary supplementation of ruminants in replacing the Mombasa grass because it provides an increase in the digestibility of nutrients for sheep. However, a limited replacement level must be implemented, considering that from 27.46%, 31.33%, 41%, and 56.65% replacement, a decline occurs in the CDCEL, CDADF, CDNDF, and CDEE, respectively, although a negative nitrogen balance does not occur.

Two experiments were carried out to determine the bioavailability of phosphorus in two spray-dried yeasts - sugarcane yeast (SCY), and sugarcane yeast + brewer's yeast (SCBY) - in starting pigs, by comparing different methods (Apparent Digestibility Coefficient of Phosphorus - ADCP; True Digestibility Coefficient of Phosphorus - TDCP; slope ratio; and standard curve). In experiment I, a digestibility assay were carried out using 30 cross breed pig with initial weigh of 22.69 ± 4.24kg, allotted in a completely randomized design. The mean ADCP and TDCP values were 62.68 and 64.15% for SCY and 77.01 and 79.33% for SCBY. ADCP and TDCP for SCBY were higher (P<0.05) than the values for SCY. In Experiment II, a growth test was conducted, 56 crossbred piglets, were utilized, with initial live weight of 15.11 ± 3.43kg, allotted in a completely randomized design, with seven treatments, four replications, and two pigs per experimental unit. The treatments consisted of a basal diet without supplementation with P and the same diet including supplementation with two levels of P (0.053% and 0.105%) from dicalcium phosphate, SCY and SCBY. The relative bioavailability mean value of 57.23% for SCY and 91.96% for SCBY, corresponding to 0.30% and 0.40% of available phosphorus, respectively.

The objective of this work was to evaluate the effects of two types of incubation and two types of feeding on the performance of chickens and intestinal development of chicks during the pre-starter phase (1 to 7 days of age). One-year-old male Ross® chicks were used. The experimental design was a randomized complete block design, in a 2x2 factorial design, with two types of feed processing (bran and micropelleted) and two types of incubation machines (single and multiple stage), totaling four treatments, with four treatment repetitions each. Twelve birds per experimental unit were used, totaling 192 animals. Performance evaluations were conducted, such as mean weight, weight gain, feed intake, feed conversion, bowel weight and size, and percentage of intestine in relation to live weight. Histomorphometric tests on the height of the villi and depth of the duodenal crypts were also performed. The two incubation machines did not influence any of the analyzed variables. Even though both had the same composition, the micropelleted feed resulted in positive gains for the performance variables: average weight, weight gain, feed intake, and feed conversion when compared to the meal, but was unable to significantly influence the morphometric measurements of the duodenum of chicks in the pre-starter phase.
