This study was conducted to investigate the effects of feeding diets containing Neem Leaf Meal (NLM), Garlic Meal (GM) and their combinations (NLM + GM) on growth performance and carcass yield of finishing broiler. A total of 180 day-old Cobb broiler chickens were divided into twelve groups of fifteen chicks with three replicate of five chicks each. The diet contained NLM, GM and NLM + GM at four levels of inclusion (0mg/kg, 500mg/kg, 1000mg/kg and 1500mg/kg). The experiment was arranged in a 3 × 4 factorial layout in a completely randomized design. Additives and levels of inclusion had no significant (P>0.05) influence on performance parameters except feed intake which was influenced (p<0.05) by NLM + GM and 1000mg/kg levels of inclusion. Final live weight (2516.67g/bird), weight gain (1742.00g/bird), daily weight gain (62.2g/bird/day) and feed conversion ratio (2.32) were improved (p<0.05) at 1500mg/kg levels of inclusion of NLM + GM. Thigh (11.68%), wings (8.44), neck (4.23%) and gizzard (2.13%) of birds fed GM were improved (P<0.05) than those of NLM. Carcass weight was influenced (p<0.05) by additives at various inclusion levels with wings (9.01%), head (3.39%), neck (4.52%), shanks (4.49%) and gizzard (2.42%) highest (p<0.05) in birds fed GM at 1500mg/kg levels of inclusion than those of 0mg/kg levels of inclusion. It was concluded that the use of NLM + GM as additives yielded commendable result on performance and carcass weight of finishing broiler birds   This study was conducted to investigate the effects of feeding diets containing Neem Leaf Meal (NLM), Garlic Meal (GM) and their combinations (NLM + GM) on growth performance and carcass yield of finishing broiler.

This study aimed to assess the effect of stocking density of 10, 12, 14, and 16 birds m?2 on performance, carcass and cut yields, productivity, and bone development of broiler chickens Cobb 500®. The experimental design was completely randomized design with four treatments (stocking densities) and four replications. The assessments were performed weekly at 1, 7, 14, 21, 28, 35, and 42 days. The best live weight result was found at a density of 10 birds m?2 in the period from 1 to 7 days. No effect of density was observed on feed intake and weight gain. From 1 to 14 days, the best live weights were found at densities of 10, 12, and 14 birds m?2, in addition to a higher feed intake at densities of 10 and 12 birds m?2. Weight gain was better at a density of 10 birds m?2, showing no differences from densities of 12 and 14 birds m?2. In the period from 1 to 21 days, live weight and weight gain were higher at densities of 10, 12, and 14 birds m?2. The highest feed intake was observed at a density of 10 birds m?2, which showed no difference from the density of 14 birds m?2. A difference (P < 0.05) was observed for live weight, weight gain, and feed intake of animals reared at densities of 10, 12, and 14 birds m?2 for the phases from 1 to 35 days and the total phase from 1 to 42 days of bird age when compared to 16 birds m?2, which presented lower performance. However, feed conversion of 1-7, 1-14, 1-21, 1-35, and 1-42 days and carcass and cut characteristics showed no significant differences for all treatments. On the other hand, productivity was higher in the treatments with 14 and 16 birds m?2, but without difference between each other. No interaction (P > 0.05) was observed between stocking density and age for the assessed bone parameters. Similarly, no difference (P > 0.05) was observed for bone development of broiler chickens reared at different stocking densities for the studied parameters. Thus, the increased density of 10 or 12 birds m?2 to 14 birds m?2 has no influence on zootechnical performance, carcass and cut yields, and bone development, but increases broiler chicken productivity reared in a conventional shed without air conditioning.

Abstract This study aimed to determine the effects of increasing Methionine (Met) supply on growth performance and carcass traits of growing-finishing pigs under summer conditions in Brazil. A total of 200 barrows and females, 63 d-old (20.43±2.0 kg), were allocated in a 2 x 2 factorial design (two Met sources [DL-Met and OH-Met] and two Met doses [100 and 120% Brazilian Nutritional recommendation) with 10 replicates of 5 animals each. Corn-DDGS-wheat-soya based diets were formulated. Treatments were offered during four phases: growing I (63-93 d old), growing II (94-114 d old), finishing I (115-142 d old) and finishing II (143-160 d old). The recommended digestible Met levels were: 0.32, 0.30, 0.29 and 0.24% respectively for the four phases. Average temperature was 27.12 ± 4.51ºC and relative humidity was 61.72 ± 5.65%. Growth performance was measured for each rearing phase. Carcass yield, back fat height, loin depth, and lean meat yield were measured at the end of the experiment. Data were submitted to a 2-way ANOVA and Tukey test. There was no significant interaction between the Met source and the dose for all performance and carcass traits. Feed intake and feed conversion ratio were similar between treatments (P &gt;0.05). The individual daily weight gain and live weight were better for the highest doses of methionine (P&lt; 0.05) in all phases and on the whole period, except for the finishing II where the weight gain was similar for all treatments. Likewise, carcass yield, lean meat was increased with the highest dose of methionine in comparison to the adequate dose. No significant difference was found between DL-Met and OH-Met on growth performance parameters. OH-Met resulted in a higher loin depth (58.37 mm) in comparison to DL-Met (55.21 mm). Overall, these results demonstrated the interest of increasing Met supply under hot conditions to improving performance and carcass quality traits.

Artificial Lighting

Light emitting diode (LED) has been used in commercial poultry industry by presenting superior energy savings and providing feasibility on production process. The objective of this research was to evaluate performance and carcass yield of broiler chickens exposed to different LED colors compared with fluorescent lamps. For that, two experiments (E1 and E2) were performed and 2,646 Cobb® chickens were used. In experiment E1, male birds were exposed to 20 lux artificial lighting with red, yellow, blue, and white LED bulbs; and fluorescent bulb. In experiment E2, male and female birds were exposed to 15 lux artificial lighting with red and blue LED bulbs; and fluorescent bulb. Cumulative weight gain (kg), feed intake (kg), feed conversion, hot carcass weight (kg), carcass yield (%), and breast and thigh + drumstick yield (%) were used as response variables. Results showed no difference (p > 0.05) among treatments for performance, carcass yield, and cut yield in experiment E1. In experiment E2 there was only difference between genders (p < 0.05) and males showed higher total weight gain, feed intake, hot carcass weight and thigh + drumstick yield. Different LED color use had same effect as fluorescent lights on broiler performance and carcass yield.

Phytase is essential for enhancing nutritional value of feed and improving animal growthperformance and health. A study was conducted to evaluate the influence of Smartchoicephytase enzyme supplementation in the diet of starter broiler chickens. A total of 150 Rossstrain broiler chicks were used for the study and allotted to five treatment groups of 30 birdseach. Each group was further divided into three replicates of 10 birds per replicate. Five isonitrogenous(21.40% CP) and iso-caloric (2975.40 kcal/kg ME) dietary treatments werecompounded to contain 0g/100kg (T ), 10g/100kg (T ), 15g/100kg (T ), 20g/100kg (T ) and 1 2 3 425g/100kg (T ) of a commercial Smartchoice phytase enzyme preparation for 28 days in a 5Completely Randomized Design (CRD). Feed and water were provided to the chicks adlibitum.Daily feed intake and weekly body weight were measured. The result showed that thedaily feed intake and daily protein intake were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation. Final live weight, daily weight gain and total weight gain weresignificantly different among treatments. Protein efficiency ratio were significantly (P<0.05)higher in T (2.10) than T (1.80) but similar to T (2.05), T (2.05) and T (1.96). Feed 1 5 2 3 4conversion ratio was significantly (P<0.05) different in T5 (2.58) and T (2.02) but similar 1(P>0.05) in T (2.02), T (2.28), T (2.31) and T (2.38). Mortality was lowest in T5. Total feed 1 2 3 4cost per bird and daily feed cost per bird were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation while cost per kg of feed and daily feed cost per bird were notsignificantly (P>0.05) affected. The findings from this study showed that Smartchoicephytase enzyme could be supplemented up to 20g per 100kg in the diet of starter broilerchickens.

This study aimed to evaluate different digestible lysine levels in diets for broilers chickens from different commercial strains, from 49 to 56 days of age, on performance and carcass characteristics. A total of 432 male broilers from 49 days old were used, with an average weight of 3560±250 g. It was used a completely randomized design in a factorial arrangement 3x4, and the birds, from three strains (Cobb 500, Hubbard Flex and Ross 308) were divided into four levels of digestible lysine (0.800, 0.950, 1.100 and 1.250%), with four replicates of 12 birds each. It was evaluated the weight gain, feed intake, feed conversion ratio, carcass yield, breast yield, breast meat yield and the yield of the thigh and drumstick. There was no interaction between lysine levels and commercial strains of broiler chickens. The different lysine levels did not influence (p ≥ 0.05) performance and carcass yield. There are significant differences between strains for feed intake and carcass characteristics. The Cobb 500 strain had higher breast yield and breast meat (p < 0.05), while the Hubbard Flex and Ross 308 strains had higher yield of the thigh and drumstick (p < 0.05).

Effect Of Feeding

SummarySeeds of the plant Crotalaria retusa L., containing 4·4% of the pyrrolizidine alkaloid monocrotaline, were fed in a finely ground form to broiler chickens at 0·005, 0·01, 0·05, 0·10 and 0·50% by weight of the diet continuously for 8 weeks.Feeding 0·005% and 0·01% had no effect on the growth performance of the birds. A non-significant reduction in live-weight gain, one death and chronic disease resulted from feeding 0·05%. At 0·10% and 0·50% there was high mortality and reduced voluntary feed intake, live-weight gain and feed conversion efficiency, the severity of the response being greater at 0·50%.Feather development was inhibited in birds fed 0·10% and 0·50% C. retusa seed.Until further research is done to determine the effect of feeding between 0·01% and 0·05% ground C. retusa seed in the diet of broiler chickens, it is suggested that the maximum should be 0·01%.

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 Impact

The acceptance of eco-friendly black soldier fly larvae meal (BSFLM) as sustainable alternative protein ingredient in poultry feeds continues to gain momentum worldwide. This study evaluates the impact of BSFLM in layer chick and grower diets on the growth, carcass quality and economic returns. Mean weekly weight gain and total live weight per chick and grower varied significantly. The highest final weight gain was achieved when birds were provided diet with 25.6% BSFLM. Average daily feed intake (ADFI), average daily weight gain (ADG) and overall weight gain of the chick varied significantly, except for the feed conversion ratio (FCR). For grower birds, ADFI, ADG, FCR and overall weight gain did not vary significantly across the various feeding regimes. The weight of the wings and drumsticks had a quadratic response with a maximum weight obtained at 33% inclusion of BSFLM. The weight of the internal organs were not significantly affected by dietary types. Positive cost–benefit ratio and return on investment was recorded for diet types with higher BSFLM inclusion levels (>75%). Diets with 25% and 100% BSFLM inclusion were the most suitable and cost-effective, respectively. Thus, BSFLM represents a promising alternative source of protein that could be sustainably used in the poultry industries.

A 4 week experiment involving 45 growing albino rats was carried out to assess the nutritional utilization of cooked full-fat soybean (CFFS) as a major source of dietary protein relative to that of the protein concentrates fishmeal-groundnut cake mixture and the response to supplementation of the cooked soybeans with 2g DL-methionine/kg diet and/or 2g L-lysine/kg diet. Feed intake (FI), average daily weight gain (DLG),. feed conversion ratio (FCR), protein efficiency ratio (PER) and feed cost (FC) per unit live-weight gain, (FC/WG) were measured, No significant effect of the various dietary treatments was observed on PER and FCIWG. However, the incorporation of CFFS either alone or in conjunction with either of both lysine and methionine significantly improved Fl and FCR (P< 0.05) and also DLG (P< 0.01) over the control fish-groundnut meal ration. Supplementation of CFFS with lysine either alone or along with methionine appeared unwarranted as methionine supplementation alone resulted in similar or slightly better efficiency of protein (0.247) and overall feed (0.596) utilization. From the results obtained, it appears that maize-based CFFS diet supplemented with 2 g/kg DL-methionine may be applicable for lion- ruminant feeding. However, since this level of methionine supplementation only provides for 67% of rat requirement, it is suggested that further studies with higher methionine levels be conducted.
