The study was conducted to investigate the potent capacity of selenium to curtail the adverse  effects of heat stress in broiler chickens. A total of 256, day old Cobb 500 broiler chicks were  randomly allotted to four experimental treatments (0, 0.1, 0.2 and 0.3 mgSe/kg), with four  replicates in a completely randomized design. Initial weight, daily feed intake, daily weight  gain, final weight, feed conversion ratio, daily water intake, feed cost/kg gain, mortality,  serum cortisol and thyroxine levels, calcium, phosphorus and ash levels in tibia bone and  faeces and weight, length and robusticity index of tibia bone were determined. Results  indicated that Initial weight, daily feed intake, daily weight gain, final weight, feed  conversion ratio, daily water intake and mortality were similar (p>0.05) across the treatment  groups and feed cost/kg gain was lower in broilers birds fed 0.3 mgSe/kg. Selenium  supplementation at 0.1 and 0.2 mgSe/kg lowered (p<0.05) cortisol and increased (p>0.05)  thyroxine level, respectively. Mineral deposition in tibia bone was similar (p>0.05), calcium  excretion was higher (p<0.05) in the control group and higher phosphorus was observed in  the faeces of broilers fed the control diet, 0.1 and 0.3 mgSe/kg. Tibia measurements were  similar (p>0.05) in all treatments.     L'étude a été menée pour étudier la puissante capacité du sélénium à réduire les effets  néfastes du stress thermique chez les poulets de chair. Un total de 256 poussins de poulets  Cobb 500 âgés d'un jour ont été attribués au hasard à quatre traitements expérimentaux (0,  0.1, 0.2 et 0.3 mgSe / kg), avec quatre réplicats dans un plan complètement randomisé.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.

A 42-day feeding trial was conducted to investigate the performance characteristics and cost benefit of feeding weaner rabbits cashew nut residue (CNR) based diets. Three dietary treatments containing: 0.10 and 20% CNR at the expense of maize on a weight for weight basis were used. Eighteen weaner rabbits (mixed breeds and sexes) were randomly divided into three groups of six rabbits each in a completely randomized design (CRD). The average daily weight gain, average daily feed intake and feed conversion ratio were not significantly influenced (P>0.05) by the dietary treatments. But rabbits fed 10% CNR based diet had the highest values for average daily weight gain and average daily feed intake while rabbits fed the control diet (0% CNR) had the least value for feed conversion ratio. No mortality was recorded for all the dietary treatments. The feed cost/kg diet (₦), feed cost/kg live weight gain (₦/kg) and cost of feed consumed/day (₦) decreased steadily with increasing level of cashew nut residue meal. The saving on feed cost (%) was not significantly affected (P>0.05) by the dietary treatments, but increased across the groups. However, the saving on feed to produce 1kg live weight was significantly (P<0.05) influenced by the CNR based diets. Rabbits fed 10% CNR based diet had the highest value of 9.66% than their counterparts fed other diets. It is concluded that cashew nut residue could be incorporated into rabbit diet at 10% without compromising the performance

The aim was to evaluate Stevia (Stevia rebaudiana Bertoni) extract (SE) effects on performance productive and gut health variables in broilers from 1 to 15 days old. SE from Stevia leaves was added to broilers diet (0.5% to 1%). Seventy-five Ross male broilers (1 to 15 days old) were distributed into T1: commercial type, without SE, T2: T1 plus 0.5% SE, T3: T1 plus 1% SE. Performance productive were measured as Average Daily Weight Gain (g/broiler/day), Average Daily Consumption Feed (g/broiler/day) and Feed Conversion Ratio (FCR). At 15 days of age, all the broilers were dissected, gut removed and processed for histomorphometric study. In gut was measured VH/CD Ratio. Results: FCR was better (P ? 0.05) in T3 and T2 than T1. In gut, VH/CD ratios showed T2 < T3 < T1 (P ? 0.05). Goblet cells number and mucus layer height were increased in broilers receive SE, especially in T2 and plasmatic cells number increased in T3. Conclusion: SE (0.5% to 1%) enhanced gut histomorphometric variables, improved gut health, mainly when SE is added at 0.5% in the broiler diet from 1 to 15 days old. It was reflexed in a better FCR in both groups received this phytobiotic.

The main aim of our study was to determine the effect of expanded and pelleted feeds, as well as the only pelleted feed based on wheat and corn, on the production of turkeys. In May 2006,, a fattening experiment on turkeys was started on the starter farm of Habar Ltd in Szarvas, owned by the Gallicoop Corporation. 17 day old male turkeys were involved in the fattening experiment. The experiment lasted 117 days. At that time, theanimals were 134 days old. After the experiment was completed, they were slaughtered. The following parameters were examined: growth, feed conversion ratio, carcass traits. Turkey feed were produced separately at different times. Similarly to the standard method of turkey fattening, 8 phases feeding was carried out. The fattening experiment was adjusted on male turkeys in 4×12×6 grouping (4 treatments: expanded and pelleted, and only pelleted corn and wheat feed; 12 repeats: number of pens/treatments; 6 birds/pen) 6-6 turkeys from 12 pens per each treatments were measured individually from the 17th day (starter) and at the time of each following feeding changes and mortality. The average of the group was calculated. The average daily weight gain, proportion of the given feed per pen, feeding changes and mortality were determined. The average daily feed intake and the feed conversion ratio were calculated.

A 126-day study was conducted to determine growth, nutrient intake and digestibility of West African Dwarf (WAD) goats fed melon husk (MH) and palm oil slurry (POS) as replacement for maize offal at 30% in concentrate diets. Sixteen goats weighing 6.5 – 7.Okg were randomly assigned to 4 dietary treatments at 4 replicates of each. Dietary treatments included control (Diet 1): 0% MH 0% POS; Diet 2: 30% MH 0% POS; Diet 3: 0% MH 30% POS; and Diet 4: 30% MH 30% POS; supplemented with Panicum maximum (grass). Data collected were statistically analysed and results showed that animals on control Diet (Diet I) had the highest (P<0.05) average daily weight gain of 31.57g/day, and a corresponding highest (P<0.05) feed intake of 365. 97g/day and best feed conversion ratio of 11.59. Animals fed Diet 3 had lowest (P<0.05) average daily weight gain of 19.42g/day, with corresponding lowest (P<0.05) dy matter intake of 334.94g/day and poor feed conversion ratio of 17.24, respectively. Variations in dry matter, organic matter and crude fibre (CF) intake were significant (P<0.05). Crude protein (CP) intake decreased progressively from diet 1 to 4, but not significantly (P >0.05). CF intake was highest in diet 4 (124.6g) and lowest in diet 1(64.72g). Ether extract (52.80g), Ash (21.48g), Neutral detergent fibre (222.88g), and lignin (60.64g) were highest in diet 4. Dry matter digestibility was highest in animals on diet 2 (86.31%) and lowest in those on diet 4 (72.28%). It was evident that goats could be fed MH and POS at the inclusion levels adopted in this study except at 30% POS inclusion level at which growth was poorest.

Cassava Peels

The nutritive potential of rumen liquor fermented cassava peels (RLFCP) was assessed in rabbit nutrition in an 8 weeks trial. The freshly collected droppings from layers were sundried, ground and mixed at 100 g/kg with ground cassava peels, sprayed with rumen filtrate and fermented for 144 hours. Thereafter, one basal diet was formulated to meet the nutrient requirement of a growing rabbit. The maize content (43 g/100 g) of the basal diet was replaced at 0, 25, 50, 75 and 100 % with RLFCP and named as diets 1, 2, 3, 4 and 5 respectively. One hundred and fifty mixed sexes healthy 5-weeks old crossbred weaner rabbits were randomly distributed among the five dietary treatments at a rate of 30 rabbits per treatment. The response criteria were growth indices, cost benefit, carcass and organ weight, blood and serum indices. While the average daily feed intake increased (49.27-58.00 g/rabbit/day) with an increased RLFCP inclusion, the average daily weight gain only increased (12.38-17.75 g/rabbit per day) when the increased RLFCP inclusion reached up to a 50 %. The feed conversion ratio of rabbits fed on the control and those fed on 25 % and 50 % RLFCP was similar (3.03-3.20) (p>0.05). Only the slaughtered weight (1116.50-1416.16 g), dressed weight (477.65-695.85 g), dressing % (42.77-50.14), relative weight (% slaughter weight) of the liver (2.18-2.57) and heart (0.20-0.23) were significantly (p

An experiment was conducted to evaluate the effects of hydroponics maize fodder on growth and nutrient digestibility of weaned piglets from July 1st, 2017 to August 11th, 2017, for six weeks. The experiment consisted of 75 days old, 15 crossbreed piglets (Duroc x Nagpuri & Duroc) in a Completely Randomized Design with three treatments and five replications. Treatment 1 (T1) contained 100% concentrate feed, Treatment 2 (T2) 90% concentrate feed and 10% hydroponics maize fodder and Treatment 3 (T3) 80% concentrate feed and 20% hydroponics maize fodder in the diet. The study revealed that hydroponics maize fodder contained DM 13.80%, CP 12.54%, NDF 47.04%, and ADL 16.51%. The treatments had non-significant effect (P > 0.05) on daily weight gain, final weight and feed conversion ratio of the piglets. However, piglets fed with 90% concentrate and 10% hydroponics maize fodder had the highest final weight (35.8±5.0 kg), while the lowest (33.6±5.00 kg) was recorded in piglets fed with 80% concentrate and 20% hydroponics maize fodder. The cost of hydroponics maize fodder production was Rs. 20.62 per kg, which was higher than the cost in the Indian context. The difference in Feed Conversion Ratio (FCR) was also not significant. However, piglets fed with T2 (1:2.58) diet recorded higher FCR than T3 (1:2.56) and T1 (1:2.51). In conclusion, the inclusion of hydroponics maize fodder in piglets diet appeared promising in growth, nutrient digestibility and cost of production.

This study was conducted to determine the effect of Ocimum gratissimum as a phytogenic feed additive (PFA) on growth performance, carcass, and blood profile of broiler chicken. One hundred and sixty day old broiler chickens were used for the study. Four diets were formulated to incorporate Ocimum gratissimum at 0, 50, 100 and 150 g per 100 kg of feed to form T1, T2, T3, and T4 respectively. The birds were divided into four groups of forty birds and each group was assigned one of the diets in a completely randomized design. Each group was further divided into four replicates of 10 birds each. Feed and water were supplied ad libitum and data collected were statistically analyzed. The result obtained showed significant (p<0.05) differences in the final weight gain (FWG), daily weight gain (DWG) and feed conversion ratio both at the starter and finisher phases. T4 had the highest significant (p<0.05) final weight gain (FWG), and daily weight gain (DWG) values. The lowest significant (p<0.05) feed conversion ratio (FCR) values were observed in T4. The feed intake of the birds was statistically similar (p>0.05) at both the starter and the finisher phases. Significant (p<0.05) increases were observed in dressed weight, dressing percentage, and cut-up parts (wing, thigh, drumstick, and breast) of the birds. T4 had the highest significant values for the carcass parameters. The haematological parameters analyzed showed significant (p<0.05) differences in the value for red blood cell (RBC), haemoglobin (Hb) and packed cell volume (PCV) values with T4 recording the highest significant (p<0.05) values for those parameters. All the serum biochemical parameters analyzed were not significantly affected (p>0.05) by the treatments. It can be concluded that Ocimum gratissimum could be added to broiler diet at 150 g/100kg as feed additive without any deleterious effect on the growth performance, carcass, and blood profiles of the birds.
