This study aimed to evaluate the use of wattle tannin as an adsorbent of toxic metals in broilers fed on diets with different levels of replacement of limestone with golden mussel meal. First, we conducted a trial to evaluate the performance of broiler chicks from 1 to 21 days old when fed on wattle tannin. For this we used 720 male broiler chicks that were one day old, in a completely randomized design with six treatments and six replications. The treatments were composed of basal diets with increasing levels of wattle tannin (0, 250, 500, 750, 1000 and 1250 g tonne-1), where the tannin replaced the inert material of the feed. All of the diets were isonutritive and isocaloric. The results showed that 250 g tonne-1 of tannin was detrimental to weight gain, final weight and feed conversion, and the use of 1000 g tonne-1 of wattle tannin, in addition to these effects, caused a drop in consumption of the ration. There was no effect of treatment on morphometric measurements of villi, crypt or the villus:crypt ratio. Next, we conducted a second test to evaluate the performance of broiler chicks from 1 to 21 days of age when fed with increasing levels of replacement (0, 25, 50, 75, 100%) of limestone with golden mussel and even supplementation or not wattle tannin. Five repetitions were used and the birds were housed in a completely randomized design. In diets with the inclusion of tannin, 250 g tonne-1 of wattle tannin was used, which replaced the inert material in the feed. In this test, 1200 male broiler chicks that were one day old were used. The results showed that the golden mussel contains large quantities of calcium, with low concentrations of toxic metals and microbiological contamination within the allowed range. Performance data show that mussel can be used to replace up to 100% of limestone in feed without affecting the variables, but the use of 250 g tonne-1 of wattle tannin affects the performance of chicks. Bone quality was not changed by the treatments. Phosphorus and calcium in the bones remained stable during treatment and only the gray variation showed interaction effects from the use of mussel and wattle tannin.

This study aimed to evaluate the use of acacia tannin as a toxic metal adsorbent in the diets of broilers fed with the inclusion of golden mussel meal in substitution for calcitic limestone. In the first trial, 648 male 21-day-old animals were divided among six treatments and six replicates, with 18 birds per experimental unit, organized in a completely randomized design (DIC). The treatments were diets with different acacia tannin levels (0, 250, 500, 750, 1000, or 1250 g ton-1). The results indicated that 250 g ton-1 of tannin was not harmful to weight gain, final weight, or feed conversion. Tannin levels caused a decrease in carcass yield and fat deposition and an increase in liver size. For the second trial, 900 male broilers of 21 days of age were used and distributed in a DIC, with different levels of substitution of calcitic limestone by the golden mussel meal (0, 25, 50, 75, or 100 %) and supplementation or not with acacia tannins (250 g ton-1), with 5 replicates and each experimental unit being composed of 18 birds. The performance data show that the use of 250 g ton-1 of tannin is detrimental to bone performance and resistance and golden mussel meal can be used to substitute up to 100 % of the limestone in the diets without affecting the variables studied.

The purpose of this study was to evaluate the effect of giving levels of secang wood extract and lemuru fish oil on the appearance of laying quails which included feed consumption, Hen Day Production (HDP), feed conversion of quail egg mortality. This study used Autumn strain quail with a population of 168 individuals with basal feed supplemented with several levels of secang wood extract. This research method is an experiment using a completely randomized design (CRD) factorial with 4 treatments with 6 replications with each repetition consisting of 7 quails aged 10-15 weeks. The treatment was as follows: P0 = basal feed without the addition of secang wood extract P1 = basal feed + 0.2% EKS + 4% MIL, P2 = basal feed + 0.4% EKS + 4% MIL, P3 = basal feed + 0 , 6% EX + 4% MIL. The addition of a combination of secang wood extract and fish oil was carried out according to the level of quail feeding. The variable being measured; feed consumption, Hen Day Production (HDP), Feed conversion, mortality. Addition of secang wood extract with a level of 0%; 0.2%; 0.4%; 0.6%, and 4% lemuru fish oil had no significant effect on feed consumption, hen day production, feed conversion, mortality, this was due to flavonoids, polyphenols and active compounds in oil. lemuru fish does not affect the appearance of quail egg production. Flavonoid compounds in low concentrations have no effect on chicken feed consumption, because the content of flavonoid compounds can still be tolerated by the chicken body. The use of lemuru fish oil with a concentration of up to 6% in quails does not affect the consumption of quail feed, because the addition of lemuru fish oil does not affect the palatability of quail feed. The conclusion of this study was that the addition of secang wood extract. The addition of secang wood extract and lemuru fish oil did not affect hen day production, feed conversion and mortality of laying quails

The experiment was carried out to evaluate the productive performance of European quails (Coturnix coturnix) in the production phase, fed with diets containing different levels of digestible lysine. A total of 175 female quails, aged 65 days, were randomly distributed in a completely randomized design with five treatments and five replicates per treatment. The animals were housed in 25 metal cages, and each cage represented an experimental parcel, with seven birds per parcel. The birds were fed the experimental rations containing 1.177, 1.217, 1.317, 1.417, and 1.517% digestible lysine. The parameters evaluated were: laying rate, mass of eggs produced, feed intake in the period, lysine intake, feed conversion per dozen and per mass. Significant differences were observed for posture rate with quadratic behavior, which indicated higher production for the level of 1.23% of digestible lysine. There was an increasing linear behavior for the feed and lysine intake, and for conversion feed per dozen and by mass, we observed quadratic behaviors. This indicates better feed conversion index when the optimal inclusion level was 1.33% and 1.404% of digestible lysine in the diet, respectively. The requirement of digestible lysine in diets for European quails is 1.404%, which corresponds to a daily intake of 421.20 milligrams of digestible lysine.

Six hundred day-old unsexed broiler chicks were used in a 42-day trial to compare the effects of different levels of palm oil supplementation on feed intake, weight gain, feed conversion and carcass quality of broilers. The chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. Each treatment had 150 broilers with 50 broilers per replicate. Four diets were formulated using locally available ingredients as diet without oil, diets containing 2.5%, 3.0% and 3.5% palm oil. All broilers had free access to ad libitum feeding. Results indicated that, supplementation of diets with different levels of palm oil significantly (p<0.05) influenced feed intake of broiler only at the age of 6th week. It was observed that as the level of supplementation increased, feed intake gradually decreased up to 6th week. Supplementation of diets with different levels of palm oil increased live weight gain of broilers. Differences (p<0.01) were observed at the end of 4th, 5th and 6th weeks of age only. Use of different levels of palm oil significantly (p<0.05) changed blood weight, heart weight and dressed weight. Survivability of broilers was higher in the supplemented group compared with without oil group. It was concluded that, supplementation of palm oil at 3.5% level in the diet of broilers resulted higher weight gain, better feed conversion and improved carcass characteristics comparing other levels. It may be concluded that supplementation of palm oil at 3.5% level in the diet of broilers resulted significantly (p>0.05) higher feed conversion ratio compared to 2.5% and 3.0% levels.DOI: http://dx.doi.org/10.3329/bjas.v43i1.19384 Bang.

Different levels of synthetic lysine amino acid were supplemented to 240 starter broiler chicks randomly distributed to 12 groups of each 20-day chicks and allocated to four treatment diets in a Completely Randomized Design (CRD). T1 (Control) basal diet (0% synthetic lysine); T2 (0.15% synthetic lysine); T3 (0.3% synthetic lysine) and T4 (0.45% synthetic lysine). There was no significant difference (P>0.05) observed between treatments in dry matter, metabolizable energy, crude protein intake, body weight and death rate of the chicks. In conclusion, there were no significant changes for all parameters and further amino acid analysis of the feedstuffs is required and extra addition above 0.45% synthetic lysine of T4 need to be added in this experiment which numerically improved the chick’s performance. Further experiments were recommended to evaluate the levels of lysine amino acid in the feedstuffs and its inclusion level in to the diet of modern broiler strains.

A 28-day feeding trial was conducted to evaluate the effect of dietary inclusion of Anth:-:: macrophylla meal on the performance of broiler starter chicks. Anthonala macrophyla was harvested from the wild, wushed, chopped into tablets, sun-dried and milled to produce the test meal. The meal contained un diy matter basis 21.11% crude protein, 1.90% crude fat, 2.00% total ash, 5.03% crude fibre and 54.36% nitrogen free extract. Five (5) broiler starter diets were formulated to contain the meal at 0,5,10,15 and 20% level, respectively. One hundred and eighty (180) day-old Anak broiler chicks were divided into 5 groups of thirty-six birds each and randomly allocated to the five treatment rations in a completely randomized design (CRD). Data were collected on feed intake, weight gain, feed conversion ratio, protein efficient ratio, cost of production of one kilogramme of each test feed among others and carcass characteristics. At 15 and 20% dietary levels. Anthonata macrophylla significantly (p<0.05) depressed feed intake, daily weight guin, feed conversion and protein efficiency ratios and final weight gain of the birds. Organ weight parameters showed no significant (P>0.05) differences among the treatments. The results of this investigation suggest that Anthonata macrophyla meal can be included in broiler starter ration up to 10% without any deleterious effect on the birds and at this level of inclusion, feed cost was reduced by 10%.

The study was carried out to determine the effect of dietary inclusion of Betaine Hydrochloride on the thermoregulatory, growth, haematological and serum biochemical indices of broiler chicks under high ambient temperature because Betaine is a organic osmolyte that can protect the birds from oxidative stress. Betaine Hydrochloride was included at 0, 1.5, 3 and 4.5 g/kg feed, respectively. One hundred and eighty, one day old Hubbard broiler chicks were allotted into four treatments with three replicates each in a completely randomized design (CRD). There were no differences (p>0.05) in the rectal temperature and heart rate across the treatments. Chicks fed 1.5 and 4.5 g/kg diet Betaine Hydrochloride had better (p>0.05) feed intake, weight gain and feed conversion ratio than birds fed control and 3 g/kg diet Betaine hydrochloride. Haematological and serum biochemical indices were similar (p>0.05) across the treatments. Betaine hydrochloride can be included in the diets of broiler chicks up to 4 g/kg diet to improve growth performance without any detrimental effect on growth, haematological and serum biochemicals.

ABSTRACT An experiment was conducted to evaluate broiler chicken performance and carcass yield in response to carbohydrase supplementation (Xylanase and Betaglucanase; XB) and association of carbohydrase and phytase (PHY). A total of 1,920 day-old male broiler chicks (Cobb 500) were distributed in a completely randomized design with 8 treatments and 8 replicates each, allocated in 64 pens with 30 chicks each. The treatments were: Positive Control (PC); Negative Control (NC): reduced ME [-120kcal/kg (Starter) and -170kcal/kg (Finisher)]; NC + XB [50g/ton]; NC + XB [100g/ton]; NC + XB [150g/ton]; NC + XB [50g/ton] + PHY [100g/ton]; NC + XB [100g/ton] + PHY [100g/ton]; NC + XB [150g/ton] + PHY [100g/ton]. The inclusion of XB (150) and XB (50, 100, and 150) associated with phytase increased feed intake than positive control when considering the total rearing phase. The feed conversion ratio of all broilers fed diets with energy reduction were worse than positive control, even with the addition of enzymes, and did not differ between them. There was no significant effect of treatments on carcass parameters.

The objective was to determine the digestible tryptophan requirements for male broilers in pre-starter and starter phases. Two experiments using 400 Cobb broilers were performed 200 males in the first experiment for the pre-starter phase (one to seven days old), and 200 males in the second experiment for the starter phase (eight to 21 days old). Chicks were housed in batter boxes made of galvanized steel as an experimental shed. The experiments were performed in a completely randomized design, with four treatments and five replicates, with ten birds each. In both experiments, the tryptophan requirement was determined using diets with different levels of digestible tryptophan. A tryptophan-deficient diet was formulated, as a basal diet, which was supplemented with increased levels of L-tryptophan in order to achieve the desirable digestible tryptophan levels. Treatments consisted of 0.209% (basal diet); 0.223%; 0.235% and 0.248% digestible tryptophan for the pre-starter phase (experiment 1) and 0.187% (basal diet); 0.200%, 0.211% and 0.223% digestible tryptophan for the starter phase (experiment 2). We evaluated feed intake, weight gain and feed conversion, as well as the metabolizability of feed nutrients. The performance and metabolic data were subjected to analysis of variance, and estimates of digestible tryptophan levels were made through polynomial regression models at 5% probability. There was no significant difference between the digestible tryptophan levels in the diet over performance and digestibility in both treatments. It is possible to conclude that the basal diet with 0.209% digestible tryptophan for the pre-starter phase and 0.187% for the starter phase, at a tryptophan: lysine ratio of 16%, as sufficient to meet the broilers requirements.
