An experiment was conducted to evaluate the effective combinations of proteases (acid, neutral and alkaline) and their concentrations on performance and carcass traits in commercial broilers fed on diets containing sub-optimal protein levels. A total of 320 broilers were used in completely randomized design with eight treatments with eight replicates in each treatment and 5chicks in each replicate. Maize-soybean meal (CD) and maize-soybean-meat cum bone meal (BD) based diets were formulated to contain 23, 21 and 19.5% crude protein (CP) and 19.5,18 and 17.5% CP, respectively during pre-starter (1-11 d), starter (12-28d) and finisher (29-42d) phases. All the diets were fed adlibitum from 1d to 42 d of age. The low protein BD were supplemented with two different combinations of proteases (1:1:1 and 2:1:1 acidic, neutral and alkaline proteases, respectively) with total activity of 2000, 4000 and 6000u/kg.The results revealed that the broilers fed CD had significantly higher body weight gain compared to those fed BD. Supplementation of proteases to the BD significantly (P LESS THAN 0.05) improved the body weight gain and feed efficiency during 21 d of age, but not during the latter phase ( 42 d of age) of growth. The broilers fed on CD had significantly (P less than 0.05) higher ready to cook and breast yields compared to those fed the BD or BD with protease supplementation. The relative weight of abdominal fat was significantly (P less than 0.05) reduced in broilers fed BD with 1:1:1 (acidic, neutral and alkaline proteases) at 4000 u protease / kg diet as compared to BD. It is suggested that addition of proteases to low protein diets had a significant positive effect in young chicken fed on maize-soybean meal and -meat and bone meal based diets.

The objective of this study was to evaluate the efficacy of supplementing a corn-wheat-soybean meal-based diet with a multicarbohydrase and phytase complex (MCPC) on growth performance, apparent total tract digestibility (ATTD) of nutrients, carcass traits, and meat quality in growing-finishing pigs. A total of 300 pigs (Duroc × Large White × Landrace; body weight = 25.3 ± 0.7 kg) were randomly allotted to three groups with 10 replicates of 10 pigs each. Pigs from three groups were fed positive control (PC) or negative control (NC), without or with MCPC diets, respectively. The MCPC supplied at least 1800, 1244, 6600, and 1000 units of xylanase, β-glucanase, α-arabinofuranosidase, and phytase per kilogram of diet, respectively. The NC diet was the PC diet but reduced in net energy (NE), digestible amino acids (dig. AA), digestible P (dig. P), and Ca by 74 kcal/kg, 7.0%, 0.134, and 0.119 percentage points, respectively. The diets were fed in 4 growth phases based on body weight (BW): phase 1: 25–50 kg, phase 2: 50–75 kg, phase 3: 75–100 kg, and phase 4: 100–135 kg. Compared to the PC, the NC diet decreased (p < 0.05) body weight gain, feed intake, and(or) feed to gain ratio during the growing/finishing phases 1, 2, 3, and 4. It also reduced (p < 0.05) the ATTD of crude protein, crude fat, P, and Ca of pigs. MCPC supplementation improved (p < 0.05) the body weight gain, feed intake, and(or) feed to gain ratio in phases 2, 3, and 4 and the ATTD of crude protein, crude fat, ash, P, and Ca for the NC diet. Additionally, dietary treatment had no effects on carcass traits and meat quality with the exception that the loin eye area in the NC plus MCPC diet was higher (p < 0.05) than the NC diet. In conclusion, the addition of MCPC to a corn-soybean meal-wheat-based diet reduced in energy and nutrients improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs.

The treatment during the embryonic preimplantation phase of Wistar rats with thePradosia huberiextract did not interfere with the water and feed consumption, as well as upon the body-weight gain. However, it has expressed a decrease of the uterine implant number, followed by the preimplantation losses at all applied doses (1.22, 6.1, and 30.5 mg/kg), and the number of embryonic resorptions in the two highest doses (6.1 and 30.5 mg/kg). After the organ weighing (hypophysis, ovaries, and uterus), only the relative weight of the hypophysis was raised at the different doses (1.22, 6.1, and 30.5 mg/kg). It was concluded that the hydroalcoholic extract ofPradosia hubericompromises the reproductive ability during the embryonic preimplantation phase, suggesting a possible toxic effect upon the reproductive system of Wistar rats.

An experiment was conducted to investigate the effect of cereal sources (maize or wheat) and omitting premix from finisher diets (from 29 to 42 days of age) on broiler performance, carcass measurements, and blood biochemical properties. Before starting an experiment, chicks were fed on two dietaries (240 chicks/maize-soybean meal and 240 chicks/wheat-soybean meal diets) from one-day old to 28 d of age. Four hundred and eighty day-old Ross-308 male broiler chicks were used in a 14-day trial (from 3/11/2016 to 16/11/2016). The experiment consisted of 4 treatments as follows: Treatment 1, no withdrawn of premix from maize-soybean meal diets, treatment 2, withdrawal premix from maize-soybean meal diets, treatment 3, no withdrawn of premix from wheat-soybean meal based diets and treatment 4, withdrawal premix from wheat-soybean meal diets. Each dietary treatment consisted of 8 replicates (15 birds/ pen). Body weight, body weight gain, feed intake, feed conversion ratios, carcass parameters, blood biochemical properties were not affected by the withdrawal of vitamin and trace mineral premixes from maize-based diets, but the reduction in body weight gain, relative weight of heart, bursa of Fabricius and abdominal fat was noticed in birds fed wheat-based diets deficient in vitamins-minerals premixes. Blood biochemical properties were not affected by cereal type and vitamins-minerals premix withdrawal.

The study was planned to evaluate the effect of exogenous fibrolytic enzymes (EFE) supplementation for 56 days @ 240 mg/kg total mixed ration (TMR) on digestibility of dry matter and nutrients in dairy cows. Six dry non-pregnant cows were assigned in each treatment with and without EFE. The digestibility trial of seven days was conducted after 49 days of feeding. Dry matter and nutrients intake of cows was not influenced by EFE. The supplementation of EFE had improved digestibility of dry matter, organic matter, crude fiber, neutral detergent fiber, cellulose (p less than 0.01), as well as digestibility of nitrogen-free extract and acid detergent fiber, was also higher (pless than 0.05). The body weight gain of cows was higher on the supplementation of EFE in TMR. The study concluded that feeding exogenous fibrolytic enzymes (240 mg/kg) supplemented TMR improved digestibility of dry matter and nutrients, which was reflected as higher body weight gain in dry non-pregnant Gir and crossbred dairy cows.

This study was conducted to determine performance, carcass traits and meat quality evaluation of sheep fed napier grass and different proportion of cocoa pod husk and soursop pulp meals. Eighteen (18) West African Dwarf rams, aged between 7 and 8 months old with mean weight of 7.00 ± 0.55kg were allotted to three dietary treatments with two replicates of three sheep per treatment in a completely randomized design. The compared treatment diets were; TA (70% napier grass and 30% concentrate diet), TB (45% cocoa pod husk with 25% soursop pulp and 30% concentrate diet) and TC (50% cocoa pod husk with 20% soursop pulp and 30% concentrate diet). The experimental diets were given to the sheep at 6% of their body weight and the experiment lasted for 84days after 14days of adjustment period. The results showed that average daily feed intake (221.79g), nitrogen intake (18.02g/day), total nitrogen loss (5.08g/day) and chilling losses (12.85%) were significantly (P < 0.05) higher in diet TA compared with diets TB and TC. Treatment diet TC was significantly (P < 0.05) better in total body weight gain (3.66kg), average daily weight gain (43.57g), total digestible nutrient (74.69%), nitrogen retention (77.58%, slaughter weight (11.02kg), hot carcass weight (5.68kg), cold carcass yields (5.23kg), hot with cold carcass yields (51.54 and 47.46%), appearance (6.81), tenderness (6.20) and overall acceptability (6.85) than other treatment diets. Initial body weight, flavor and juiciness were not significantly (P > 0.05) affected by the treatment diets. It was concluded that 50% cocoa pod husk with 20% soursop pulp and 30% concentrate diet has the potential to enhance performance, carcass traits and meat quality evaluation in sheep.

In order to decide the optimum time of grazing for camels during hot summer months, 10 growing camel calveswere divided into 2 equal groups. First group was sent for grazing during 10:00 h to 16:00 h daily and second groupallowed for grazing during thermo neutral period. The climatic variables were recorded daily (April 2012 to March2013). The average daily gain and total body weight gain in calves sent for grazing during relatively cool parts ofday (group 2) was significantly higher as compared to group 1 calves sent as per routine farm schedule. Theaverage intake of fodder and water from manger was higher in group 1 calves. The average DMI from manger forgroup 1 calves was higher as compared to group 2 calves. The comparative biometrics of camel calves in differentgrazing management practices revealed that body length, heart girth, height at wither, neck length were significantly(P&lt;0.01) higher in group 2 calves as compared to group 1 calves. After 180 days of experimentation, humpcircumference vertical and hind leg length were significantly (P&lt;0.05) increased in group 2 as compared to group1. Analysis of recorded data of climatic parameters revealed that average maximum temperature was higher duringJune 2012. The values of THI also were higher in monsoon and post monsoon months hence the practice of sendingcamel calves during relatively comfortable part of hot and hot humid months was successful in getting good growth.The relative humidity was significantly higher during morning as compared to evening period for all months. TheTHI was significantly lower during morning as compared to evening hours for all months in different climate forwhole year. Economic analysis reveals that the cost of feed per kg body weight gain was quite less in group 2 ascompared to group 1. So the practice of grazing of camel calves during cool hours of day remain profitable forfarmers by looking at the body weight gain and better body conformation in climate change condition.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Abstract This study aimed to evaluate the effect of zinc supplementation in various diets on the performance and health status of IPB-D2 chickens. Subsequently, about 180 one-week-old IPB-D2 chickens were used in the study and were fed the treatment diets for 12 weeks. Also, this study employed a completely randomised factorial design with six treatments and three replications of ten birds each. These treatment diets included A1, which contained nutrients based on SNI (2013) without Zn supplementation, A2 which is a combination of A1 and 60 ppm of Zinc, B1 which contained nutrients 5% higher than SNI without Zn supplementation, B2 which is a combination of B1 and 60 ppm Zinc, C1 which contains nutrients 10% higher than SNI without Zn supplementation, and lastly, C2 which is a combination of C1 and 60 ppm of Zinc. Furthermore, the data were analysed using ANOVA, and the parameters observed were the body weight, body weight gain, feed consumption, feed conversion ratio, blood profile and the villi surface area of the jejunum. Consequently, the results showed that C2 significantly (P<0.05) increased the body weight and body weight gain when fed to the finisher and grower chickens, respectively. More so, when the finisher chickens were fed the 10% SNI diet, there was an increased body weight gain and also a significantly (P<0.05) decreased feed conversion ratio. Furthermore, the addition of 60 ppm zinc increased haemoglobin significantly (P<0.05), whereas C2 decreased leukocytes significantly (P<0.05) in chicken blood. However, the treatments had no effect on feed consumption in the villi surface area of the jejunum. Therefore, the study concluded that supplementing the IPB-D2 chickens with 60 ppm zinc in a 10% SNI diet resulted in the best performance and health status.
