The objective of the current study was to examine the effects of mannan-oligosaccharides or inulin on HF dairy heifers’ starter feed intake and daily weight gain in farm situations. We measured these parameters across two experiments. In Trial 1 (T1), next to the control group, 15-15 HF heifers received MOS or inulin supplementation from 1st day of age to weaning. The amount of the supplementations changed according the calves’ age and the amount of milk replacer from 12 g to 24 g/calf/day. We measured the individual feed intake daily, the live weight at 0, 14, 21 and 60 days. In the second experiment (T2) we used 30 HF heifers also in three group (Control, MOS, Inulin) but we gave more from the experiment materials (28 g/calf/day MOS or Inulin). We started dosing the supplements with the colostrums feeding, and gave up on 14th day of age. We also measured the individual feed intake daily and the live body weight (BW) at 0, 14, 28, 42 and 56 days. The treatments in T1 did not cause significant differences in average feed intake, body weight and average daily weight gain. When the calves got the supplementation with colostrum too, the ADWG was significant lower in the group fed inulin than control and group fed MOS (P<0.05). We calculate the ADWG all of the experimental periods. From 0 to 14 day, and from 0 to 56 day the ADWG in inulin group was lower than control group, but the datas of group MOS did not differ from the others. Due to the distribution of the birth weights, the lower ADWG did not manifest in differences in body weight in other points of the experiments. We did not find an interaction between the treatments and the daily feed intake of calves. According with our measurements,

An experiment was conducted to evaluate efficacy of Lacto acidophilus on the growth performance, carcass characteristics and nutrient digestibility of broiler chickens. Two hundred and twenty five (225), one day old chicks were purchased from local commercial hatchery and were randomly divided into 5 groups and each group had 3 replicates of 17 chicks in a completely randomized design. Five iso-caloric and iso-nitrogenous (ME 2998kcal/ kg and CP 23.21%) broiler starter and finisher (ME 2990 kcal/ kg and CP 20.33%) experimental diets containing 0, 150, 200 and 250g Lacto acidophilus® for T1-T4 respectively and T5 containing Oxytetracycline were formulated. Broiler starter and finisher diets were fed from 0-3 and 4-7 weeks, respectively. Data obtained were subjected to analysis of variance using Statistical Analysis System and significant differences between treatments means were separated using Duncan Multiple Range Test. There were significant (P<0.05) difference in final weight, weight gain, average daily weight gain (ADWG), total feed intake (TFI), average daily feed intake (ADFI), feed conversion ratio (FCR) and feed cost/kg gain across the treatment groups. It was observed that chickens fed dietary Oxytet (oxytetracycline) had the best results in terms of the final body weight, weight gain and ADWG but similar to those fed 150 and 200g Lacto acidophilus® addition levels. The percentage dry matter (DM), crude protein (CP), crude fibre (CF), ether extracts (EE) and ash retention increased with increase in Lacto acidophilus® inclusion with exception for 250gLacto acidophilus® inclusion (CP, CF, EE). However, it was observed that chickens fed dietary levels of Lacto acidophilus® had the best live weight, dressed weight and dressing percentage compared to the control group. It was concluded that chickens fe Lacto acidophilus® inclusion may as well compete favorably with antibiotics growth promoter fed chickens.     Une expérience a été menée pour évaluer l'efficacité de Lacto acidophilus sur la performance de croissance, les caractéristiques de la carcasse et la digestibilité nutritive des poulets de gril. Deux cent vingt-cinq (225), poussins d'un jour ont été achetés à l'écloserie commerciale locale et ont été répartis au hasard en 5 groupes et chaque groupe avait 3 répliques de 17 poussins dans une conception complètement randomisée. Cinq iso- caloriques et iso-azotés (le 'ME' 2998kcal/kg et le 'CP' 23.21%) démarreur et finisseur de poulet de gril (le 'ME' 2990 kcal/kg et le 'CP' 20.33%) des régimes expérimentaux contenant respectivement 0, 150, 200 et 250 g d'acidophilus lacto® pour le T1-T4 et le T5 contenant de l'Oxytetracycline ont été formulés. Les régimes d'entrée et de finisseur de poulet de gril ont été alimentés de 0-3 et 4-7 semaines, respectivement. Les données obtenues ont fait l'objet d'une analyse de la variance à l'aide du système d'analyse statistique et des différences significatives entre les moyens de traitement et ils ont été séparées à l'aide du test à distance multiple Duncan. Il y avait une différence significative (P<0,05) dans le poids final, le gain de poids, le gain de poids quotidien moyen (le 'ADWG'), la consommation totale d'aliments pour animaux (le 'TFI'), l'apport quotidien moyen en aliments pour animaux (ADFI), le ratio de conversion des aliments pour animaux (FCR) et le gain coût/kg des aliments pour animaux dans les groupes de traitement. On a observé que les poulets nourris oxytet alimentaire (oxytetracycline) ont eu les meilleurs résultats en termes de poids corporel final, gain de poids et de 'ADWG', mais similaire à ceux nourris 150 et 200g Lacto acidophilus® niveaux d'addition. Le pourcentage de matière sèche (le 'DM'), de protéines brutes (le 'CP'), de fibres brutes (le 'CF'), d'extraits d'éther (le 'EE') et de rétention de cendres a augmenté avec l'augmentation de lacto acidophilus® l'inclusion à l'exception de 250 glacto acidophilus® inclusion (CP, CF, EE). Cependant, il a été observé que les poulets nourris à des niveaux alimentaires de Lacto acidophilus® avaient le meilleur poids réel, le poids habillé et le pourcentage de vinaigrette par rapport au groupe témoin. Il a été conclu que les poulets feLacto acidophilus® inclusion peut aussi bien rivaliser favorablement avec les antibiotiques promoteur de croissance nourris poulets.

An eight weeks restricted feeding trial was conducted to investigate the effect of restricted feeding and strain on the growth performance and haematological parameters of two strains of pullet chicks. Five hundred and forty chicks comprising of Isa Brown (270) and Bovans Nera (270) strains were assigned to six treatments arranged in a 2 x 3 factorial arrangement of Isa Brown and Bovans Nera on ad libitum (R ), skip-a-day (R ) and skip-2-days (R ) restrictions per week, respectively. Final live weight and weight gain of pullet chicks reduced (P < 0.05) with increasing level of feed restriction. Chicks on ad libitum showed improved (P<0.05) final live weight and weight gain. Results showed significant (p<0.05) reduction in feed intake and body weight of chicks due to restricted feeding. The birds maintained on R feed restriction group recorded the highest significant (p<0.05) values of final body weight (544.57g), feed intake per day (33.70g/day) and daily weight gain (9.82g/day). R birds recorded significantly (p<0.05) higher values of final weight, feed intake and weight gain when compared with R birds with final body weight of 480.84g, daily feed intake of 28.42g/day and daily weight gain of 8.48g. Furthermore, Bovans Nera pullet chicks recorded significantly higher (p<0.05) final weight and daily weight gain when compared with the Isa Brown birds of same age. The R pullets had significantly higher (p<0.05) white blood cells when compared with the R and R birds. Heterophil/lymphocyte ratio (0.52) was  significantly (p<0.05) lower with the Isa brown birds.

One hundred and twenty (120) 16 weeks old White Leghorn layer breeds were used for the study. The objective of the study was to determine effect of photoperiod on layer chicken. The research was carried out at the Poultry Section of the Animal farm of the Department of Animal Science Education, Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development, Mampong. Four treatments made up of 12 hours of light, 14 hours of light, 16 hours of light and 18 hours of light were used for the study. Each treatment was replicated three times with 10 birds per replicate in a Completely Randomized Design. Birds were exposed equally to common daylight and in the evenings, lights were turned on at specified periods. Growth parameters measured were initial body weight, daily feed intake, daily weight gain and final body weight. Egg traits measured were egg weight, albumen height, yolk color and yolk weight. The data collected were analyzed using General Linear Model procedure of Statistical Analysis System. Results from the study indicated that, varied photoperiod regimes had no significant (P>0.05) effect on initial body weight, daily feed intake but had significant (P<0.05) effect on daily weight gain and final body weight of growth traits. Photoperiod had no significant (P>0.05) effect on the egg characteristics of the white Leghorn layer bird. It was concluded from the study that, increasing photoperiod had no positive effect on growth and egg characteristics of the white Leghorn layer.

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 In the United States, bioethanol is generated from corn and biodiesel from soybean oil to reduce the dependence on fossil fuels. Ethanol production generates DDGS, high in bypass protein and soluble carbohydrates, which can be used as a cheaper alternative replacement for corn and soybean. This experiment was conducted to evaluate voluntary feed intake, body weight gain and blood metabolites of lambs fed legume-based diets supplemented with corn and soybean meal or dried distillers grain with solubles (DDGS). Animals were individually housed in pens (1.52 mx 1.52 m) under a modified carport shed with woodchips as bedding. They were stratified into four groups (n = 9) with similar weights and standard deviation and randomly assigned to four treatments. The lambs were fed ground sericea hay (SL) or alfalfa meal (ALF) with either corn and soybean meal (control) or DDGS for 60 days. Treatments were SLC, SLDDGS, ALFC and AFLDDGS. The lambs were fed ad libitum based on their selected treatment and given water daily. At the end of the 60 days, weights and blood samples were collected. Plasma samples were analyzed for blood urea nitrogen (BUN), glucose and non-esterified fatty acids (NEFA). Data were analyzed using Proc Mix Procedure of SAS. Results indicated that replacing corn with DDGS did not (P &gt; 0.05) affect voluntary feed intake, final live weight and carcass weight. Blood NEFA and glucose were not affected by dietary treatments. BUN increased in lambs fed alfalfa with corn and soybean meal compared to animals fed either legume supplemented with DDGS. Similarly animals fed sericea have lower (P &lt; 0.05) BUN (19 vs 23 mg/dL) when corn and soybean meal were replaced with DDGS. DDGS can be used in legume diets for growing lambs in replacement for corn and soybean meal.

Increasing concern about some animal production systems has placed considerable value on humanitarian breeding systems, aimed at ensuring animal welfare and comfort. Raising calves is one of the most important stages in a milk production system. This study aimed to evaluate and compare the performance of Holstein dairy calves raised by two farming systems: conventional individual (CI) and collective with automatic calf feeder (CACF). Fourteen, 15-day-old Holstein dairy calves having an average initial body weight of 40 kg, were used. The animals were distributed in a completely randomized design with seven animals per treatment. The variables evaluated were the milk and feed intake, body weight, hip height, thoracic circumference and daily weight gain. The average milk intake was lower in the CACF (3.5 L animal-1 day-1) than CI (5.1 L animal-1 day-1) system. However, the feed intake was higher in the CACF (1.205 kg animal-1 day-1) compared to CI (0.910 kg animal-1 day-1) system. Body weight, thoracic circumference, hip height and daily weight gain were similar between the two systems. The CACF raised calves had a higher concentrate intake and lower milk intake than the calves raised under the CI system.

The purpose of the research is increasing the average daily gain of animals due to the use of the Bisolbi drug. The effect of Bisolbi preparation based on Bacillus subtilis H-13 1.5×108 (LLC «Bisolbi-Inter») on the biochemical and productive life of calves was studied. The scientific and production experiment was carried out on the basis of a dairy farm of the State «Kupinskoe» Unitary Enterprise of the Samara region involving 30 Holstein-Friesian calves. The biological effect of the drug is provided due to its adsorption properties, the ability to enhance the activity of a number of enzyme systems and increase the digestive and systemic immunity of the body. The drug use increases the integration intensity of animals: the amount of total protein in the blood serum of calves of the experimental group at 120 days of age was higher by 8.9% (p<0.05), albumin – by 9.2% (p<0.01), compared with the animal data of con-trolled group. The Bisolbi indication contributed to an increase in the intensity of carbohydrate-lipoid metabolism: the cholesterol amount was higher by 23% (p<0.01), the glucose content – by 0.4 mmol/l (p<0.05) in the blood of 120 day old calves of the experimental group, compared with the data of controlled animals. It was found that the body weight of calves in the control group of 100 days age was 105.23±2.11 kg, in the experimental group – 108.6±2.19 kg, which is 3.37 kg higher. The average daily weight gain of animals in experimental group was signif-icantly higher by 0.075 kg (p<0.01). At 120 days of age, the body weight of the experimental calves was higher by 4.19 kg (p<0.05), the average daily weight gain by 0.080 kg (p<0.05), compared with the data of the controlled ani-mals. The indication of Bisolbi 5-10 ml (LLC «Bisolbi-Inter») to calves daily for 2 months resulted in an additional profit constructively of 137 rubles from each head.

Two hundred and twenty five day old straight run broiler chicks were utilized in completely randomized design to test the effect of restricting feed intake of four groups of chicks to 92.5% 85.0%, 77.5% and 70.0% of the unrestricted (control) group in the starter phase and following adlibitum feeding for all groups in the finisher phase. The treatments were simply designated as A, B, C, D and E. The starter phase in which the restriction was carried out lasted 28 days and the finisher phase 42 days. Parameters evaluated during the starter and finisher phases included; growth rate, feed conversion ration and mortality rate. Results show gain in weight among all groups while the group fed diet B and the control had comparable weight gain at the starter phase. The percentage weight difference between the control and each of the other dietary groups was: 4.4%, 8.4%, 8.6% and 10.4% for the treatments B, C, D and E respectively. Feed gain ration improved as the level of restriction became stricter. Following ad-libitum feeding of all grops at the finisher phase, the feed restricted groups at the starter phase voraciously increased their feed intake, thus, producing comparable performance values with the unrestricted (control) group in weight gain in the 8th week of the study. Although birds in all groups averaged more than 2000g final live weight in 10weeks, significant differences exist between groups that were fed diets C, D, and E that were restricted at the starter phase, an indication that complete compensatory growth was not obtainable. Feed gain ration improved for restricted groups. Mortality rate did not show any trend attributable to levels of feed restriction. This study shows that broiler chicks fed restricted levels of balanced diet at the starter phase but later fed ad-libitum at the finisher phase could attain a finished weight of about 2000g or more at a market age of 10 weeks (70 days) with an improvement in feed gain ration.

AbstractThe objective of this study was to evaluate how the inclusion of a blend of essential oils in milk replacer (MR) affects different outcomes of dairy heifers. The outcomes evaluated: feed intake, performance, body development, blood cells and metabolites, insulin-like growth factor-1 (IGF-1), rumen fermentation, fecal scores and respiratory scores. All outcomes were evaluated during pre-weaning (4 – 60 d of age), and carryover effects on post-weaning (61 – 90 d of age) periods. The experimental units utilized were 29 newborn Holstein × Gyr crossbred dairy heifers, with genetic composition of 5/8 or more Holstein and 3/8 or less Gyr and body weight (BW) at birth of 32.2 ± 5.2 kg. Experimental units were randomly assigned to either a control group (CON, n = 15) or a treatment group, consisting of supplementation of a blend of essential oils (BEO, n = 14) with1 g/d/calf (Apex Calf, Adisseo, China). During the pre-weaning phase, all heifers were fed 5 L of MR/d reconstituted at 15% (dry matter basis), divided into two equal meals. Water and starter were provided ad libitum. During the post-weaning, animals received a maximum 3 kg of starter/d, and ad libitum corn silage, divided into two meals. The outcomes feed intake, fecal and respiratory scores were evaluated daily. BW was measured every three days, while body development was recorded weekly. Blood samples were collected on 0, 30 and 60 d of age for total blood cell count, weekly to determinate ß-hydroxybutyrate, urea and glucose, and biweekly for IGF-1. Ruminal parameters (pH, volatile fatty acids, ammonia-N and acetate:proprionate proportion - C2:C3) were measured each 14 days. A randomized complete block design with an interaction between treatment and week was the experimental method of choice to test the hypothesis of effect of BEO on all outcomes. An ANOVA procedure was used for continuous outcomes and a non-parametric test was used for the ordered categorical outcomes both adopting a C.I. = 95%. Results indicated that there was not enough evidence to accept the alternative hypothesis of effect of BEO in MR on: feed intake, performance, body development and blood metabolites during both pre-weaning and post-weaning periods. However, results indicated that the inclusion of BEO in MR significantly affects the proportion of C2:C3 during pre and post-weaning (P ≤ 0.05). Similarly, the effect is significant for basophil (P ≤ 0.001) and platelet (P ≤ 0.05) counts in pre-weaning. The interaction between week and treatment was also significant for lymphocytes (P ≤ 0.001), revealing a long-term treatment immunological effect. Lastly, the effect on fecal scores was also significant (P ≤ 0.05) during pre-weaning, with lower values for BEO. BEO contributed for ruminal manipulation on pre-weaning and carry over effect on post-weaning; immunity improvement and a decrease morbidity of neonatal diarrhea in pre-weaning phase.
