The objective of the study was to determine the interaction of pen enrichment and sex on growth performance and blood metabolite concentrations of Windsnyer pigs. Forty-eight growing Windsnyer pigs of both sexes, with an average initial body weight of 21.6 (±9.01) kg were used. Daily feed intake and weekly body weights for each pen were measured. Blood was collected at the end of the experiment. Pen environment did not affect average daily feed intake (ADFI) and average daily gain. There was a pen environment and sex interaction on ADFI. Females in barren pens had higher ADFI than enriched females but ADFI in barren and enriched pens was similar for male pigs. Pigs in enriched environment were more efficient in converting feed into body weight than those in barren environment. There was an interaction of pen environment and sex on glucose, blood urea nitrogen (BUN), and alkaline phosphatase. Enriched males had higher albumin than males in barren environment. Enriched females had higher BUN than females in barren environment. It was concluded that enriched Windsnyer pigs housed at a density of 0.39 m2 per pig, particularly females, perform better than those in barren environments.

Jack Bean

A total of fifty 3-4 weeks old albino rats of the Wistar strain weighing 50-60g were randomly allocated to five dietary treatments in a completely randomized block design to investigate the growth performance and nutrient digestibility of the rats fed diets containing processed dehulled jack bean. Five diets were formulated to contain casein (T1)-control diet, dehulled jack bean soaked in filtrate obtained from raw pap(T2), dehulled jack bean soaked in lye solution (T3), dehulled jack bean boiled for 15minutes (T4) while a protein free diet served as a negative control (T5). The experiment lasted for 28-days.Dehulled jack bean significantly (P>0.05) influenced the growth parameters measured for the Wistar rats. Rats on control diets had the highest value for all the growth indices, feed intake (210.90g), final body weight (103.40g), body weight changes (41.90g), feed conversion ratio (5.10) and protein efficiency ratio (1.41). Rats on T2 (soaked in ‘ogi’ liquor) had feed intake value of (147.40g), followed by rats on T4 (boiled for 15minutes) (117.00g), T5 (negative control) (119.07) and T3 (soaked in lye solution) (79.40g) respectively. Rats on T4 had the highest value for final body weight (67.80g), body weight changes (6.30g), feed conversion ratio (12.27) and protein efficiency ratio (0.25) while rats on T3 had the lowest value for final body weight (67.80g), body weight changes (-32.45g), total feed intake (79.40g) with FCR of (-0.96) for the tested diets. Wistar rats placed on lye treated diet had depressed body weight changes of 59.8% compared to the control. Digestibility studies however showed that rats on control diets had the highest digestibility value of DM and other nutrients, while there was no significant (P<0.05) difference in digestibility value of CF, significant (P>0.05) differences existed in DM, digestibility value of CP, EE and Ash. Rats on T3 and T5 had the lowest digestibility value for Ash (11.48) and CP (37.66). Rats fed dehulled jack bean seed soaked in ogi liquor and boiled for 15minutes showed slight improvement in growth performance and nutrient utilization over those fed lye soaked jack bean. All the processing methods were ineffective when compared to the performance of rat fed casein based diets.

An experiment was carried out to determine the growth performance and haematological indices of Red Sokoto goats placed on oil palm leaf meal (OPLM)-wheat offal based diet. Six goats aged 12-18 months, weighing 15 – 20kg were randomly assigned to three treatments, comprising two animals each in a Completely Randomized Design. Each animal received 1kg of the diet daily for 56 days and weighed weekly. Results showed that final body weight was significant (P<0.05) with goats on T3 having the highest (21.50kg). The feed intake, body weight gain and Feed Conversion Ratio (FCR) were significantly different (P<0.05). T3 had the highest feed intake (305.35g/d), highest body weight gain (90.84g/d) and the best FCR (3.36). Significant differences (P <0.05) were observed in the Red Blood Cell (RBC), Packed Cell Volume (PCV) and Haemoglobin (Hb) counts, ranging between 3.12 - 4.20x106ml; 23.00 -30.50% and 7.70 - 10.15g/dl respectively with goats on T3 having the highest.  The inclusion of OPLM enhanced body weight gain, FCR, RBC, PCV, and Hb counts of the goats. Therefore the oil palm leaf meal diets are recommended for better goat production. Key word: Growth performance; Oil Palm Leaf meal., Blood profile., Creatinine., Red Sokoto Goat.

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.

Weaning Age

Abstract Lactose is an effective carbohydrate source for nursery pigs. Weaning age could influence needs for lactose. Weaning ages can vary among producers depending on preferred management programs. This study aimed to evaluate optimum levels of lactose for pigs at 7 kg BW weaned at different ages. A total of 1,632 pigs were weaned at d21 (d 21.2 ± 1.3) or d25 (d 24.6 ± 1.1). Pigs had a common diet until they reach 7 kg BW. Within a same weaning age group, when pigs reached 7 kg body weight, they were allotted to 4 dietary treatments with 6, 9, 12, and 15% lactose. Feed intake and BW were measured after 10d feeding when pigs reached 11 kg BW. Data were analyzed using the MIXED procedure of SAS for a slope ratio analysis to test effects of lactose levels on growth performance of pigs influenced by their weaning ages. Pigs weaned at d21 had Phase 1 for 11 days whereas pigs weaned at d 25 had Phase 1 for 2 days to reach 7 kg BW. According to the slope ratio analysis, as increasing lactose intake, ADG of pigs weaned at d21 responded greater (P &lt; 0.05, 68.5%) than growth of pigs weaned at d25. There was no change of slope in feed intake of pigs weaned at d 25 by increasing lactose intake. However, G:F of pigs weaned at d 25 responded greater (P &lt; 0.05, 250%) than G:F of pigs weaned at d21. In conclusion, pigs weaned at d21 grew faster from 7 to 11 kg BW as lactose intake increased compared with pigs weaned at d25 potentially because pigs weaned at d21 had an extended time for adaptation and recovery from weaning stress until they reached 7 kg BW.

Com o objetivo de avaliar o efeito de duas linhagens (italiana e japonesa) e de dois níveis de proteína bruta (20 e 26% PB) sobre o desempenho para corte foram utilizados 144 machos de codorna, criados em gaiola de 1 a 49 dias. Foram alojadas nove aves por gaiola, sorteadas de acordo com um esquema fatorial 2 x 2 em delineamento inteiramente aleatorizado com quatro repetições. O desempenho foi avaliado semanalmente. A linhagem italiana apresentou maiores peso médio, ganho de peso médio e consumo médio do que a japonesa. O consumo médio relativo e a conversão alimentar da linhagem italiana foram menores, indicando melhor capacidade de utilização do alimento. Abstract Male quails (144) were reared from 1 to 49 days in cages, to evaluate the effect of line (Italian and Japanese), and crude protein level (20 and 26% CP) upon growth performance for meat production. Nine birds were housed per cage, sorted out according to a 2 x 2 factorial scheme in an entirely randomized design with 4 repetitions. Growth performance was evaluated weekly. The Italian line had higher mean body weight, mean gain weight and mean feed intake than the Japanese line. The Italian line showed lower or equal means of feed intake adjusted for body weight, indicating that it had better feed utilization. Mean feed conversion of the italian line was better than that of the Japanese line.

In this study, we aimed to evaluate the effect of the addition of different probiotics to commercial diets for piglets on diet digestibility, total bacterial count (TBC) of faeces, Clostridium count and growth performance. In the digestibility assay, 24 entire male pigs with an average initial body weight of 18.8 ± 0.87 kg were housed individually in metabolism cages and distributed in a completely randomised experimental design; this consisted of three treatments (probiotic-free commercial feed; commercial feed with the addition of 0.2% probiotic containing a blend of microorganisms; commercial feed with the addition of 0.1% yeast-based probiotic Saccharomyces cerevisiae boulardii) and eight replicates. The digestibility of the feeds was determined. At the end of the experiment, 25 grams of faeces were collected for microbiological analysis. In the subsequent experiment, 150 crossbred piglets (entire males and females), weaned at 21 days of age and having an average initial body weight of 6.81 ± 0.71 kg were distributed in a randomised complete block design, with six treatments repeated twice in the first and thrice in the second block, totaling five replicates and five pigs per experimental unit. The treatments, arranged in a 3 x 2 factorial arrangement, consisted of a combination of the three experimental diets used in the digestibility test and two genders. The growth performance in the nursery was evaluated during the following phases: pre-starter I (21 to 29 days), pre-starter I and II (21 to 40 days) and the total period (21 to 63 days). There was an effect (p < 0.05) of the diets on the digestible protein and the logarithm of the TBC. There was no effect (p > 0.05) of the interaction or the diets on the growth performance of the pigs in any of the phases. Both in the entire experimental period and in the pre-starter I and II phases, male pigs presented better feed conversion (p < 0.05) than females. There was an improvement in the apparent digestibility of the crude protein of the feed when the pigs were fed commercial feed containing probiotics. Pigs fed commercial feed containing probiotics based on yeast Saccharomyces cerevisiae boulardii presented a reduced TBC in their faeces. Commercial feed containing probiotics did not influence the growth performance parameters of nursery phase piglets.

A study was conducted to assess the growth performance of broiler chickens fed Moringa oleifera leaf (MOL) feed supplement and challenged with a very virulent infectious bursal disease virus (vvIBDV). Two hundred and forty day-old Ross 308 hybrid broiler chicks were randomly assigned into groups A, B, C and D of 60 chicks each and were raised in deep litter housing. Broiler starter (BS) and broiler finisher (BF) mash were formulated each with 5% MOL included as part of the feed ingredient for broilers in groups A and B while BS and BF for broilers in groups C and D were formulated without MOL. Broiler chickens in groups A, B and C were challenged at 35 days of age with 0.05 ml of a live vvIBDV, while those in group D served as control. Daily feed intake (DFI), feed conversion ratio (FCR) and average body weight gain (ABWG) was used to assess the growth performance. At 42 and 49 days of age, significant difference was observed in the feed intake of broilers in groups A, B and C when compared with group D (p = 0.0001). At 49 days of age, broilers in group A and D significantly (p = 0.0001) added more weight than those in groups B and C respectively. Broilers in group B had a significantly (p = 0.0006) lower FCR than those in group A, C and D at 28, 35 and 42 days of age. Despite the challenge with vvIBDV, MOL inclusion in the diet of broiler chickens resulted in reduced DFI, good FCR, increased ABWG and final body weight and carcass weight.

Production Factors

The aim of this study was to identify and quantify, through mathematical models, the production factors of grow-finishing (GF) phases that influence the daily feed intake (DFI) and feed conversion ratio (FCR) in pigs. Sixty-five GF farms were evaluated between 2010 and 2013, linked to a cooperative system located in the western Parana State, Brazil, representing 463 batches, with a mean of 642.79 ± 363.29 animals per batch, equalling approximately 300,000 animals. Forty production factors were considered that related to management, sanitation, installations and equipment, nutrition, genetics and environment on the farms. The DFI was influenced by the barn's position relative to the sun (P = 0.048), initial body weight (P < 0.0001) and final body weight (P < 0.0001). It was observed that the FCR was influenced by the barn’s position relative to the sun (P = 0.0001), the use of humidifiers/misting (P = 0.03), the presence of composters (P = 0.006), trees on the sides of barns (P < 0.045), the initial body weight of the pigs (P < 0.0001) and duration of the grow-finishing phase (P < 0.0001). The variables selected in the models explained approximately 44 and 20% of the total variance in the DFI and FCR, respectively, demonstrating that this resource is a good tool for interpreting the factors related to the parameters evaluated.

This experiment was aimed to evaluate the effect of fermented cocoa pod as feed for Bligon goats. Sixteen Bligon goat with a body weight of 11-13 kg were put into individual cages which were equipped with feed and drink containers. The study design used a randomized block design, where initial body weight in as peragam with four treatments and four replications. Fermented cocoa pod used Trametes versicolor. The experimental treatments were T1= 30% of fresh king grass + 50% of dried king grass + 20% of concentrate; T2= 30% of fresh king grass + 30% of dried king grass + 40% of concentrate; T3= 30% of fresh king grass + 30% of cocoa pod + 40% of concentrate; and T4= 30% of fresh king grass + 30% of cocoa pod fermented + 40% of concentrate. Observed variables were feed intake, body weight gain and feed conversion. The result showed that fermented cocoa pod at the level of 30% had higher (P<0.05) infeed intake (560.33 g day-1), body weight gain (101.79 g head-1day-1), and feed conversion (5.50) compared to other treatments. The conclusion of this study were the use of 30% cocoa pod fermented in the ration showed the best body weight gain and feed conversion on Bligon goat performance.
