  Background: The ban of antibiotics use as growth factors since 2006 affects animal performance and economical viability of farms. Several alternatives including incorporation of organic acids in feed or drinking water in order to improve productivity were studied. Objective: The objective of this study is to mix ACIDAL with drinking water of hens in order to improve productivity. Methodology: The experiment was carried out with 360 ISA Brown hens (22-44 weeks of age), allocated to 3 groups (control, Aci 1 and Aci 2) of 120 birds each. The three groups received, respectively in drinking water 0, 1 and 2 mL of ACIDAL L–1. Prior to start, every 4 weeks and at the end of the treatments, samples of chicken droppings according to each group were collected and used to determine total Streptococcus and Escherichia coli and to check the presence of Salmonella. During treatments, amount of water consumption, feed intake, body weight, egg weight and egg component weights were recorded weekly. Results: Eggs produced were collected daily and every 2 weeks, the litter quality was assessed. Mixing of ACIDAL with drinking water of laying hens reduced significantly the number of total bacteria, eliminated completely Salmonella in the droppings, decreased feed intake and improved egg weights and body weight compared to control group witch litter was significantly wetter and more tendentiously crusty compared to those of treated groups. Conclusion: In opposite, there is no effect on water consumption, mortality rate, egg laying rate and ratios of albumen, yolk and shell.

  Background and Objective: Difficulties in satisfying the energy requirements of birds with cereals, especially maize, have led researchers to investigate the effects of different levels of dietary palm oil on the production performance of laying hens. This study was conducted to investigate the effects of dietary palm oil on the egg production performance and serum parameters of laying hens. Materials and Methods: One hundred eighty 55-week-old Isa Brown laying hens were used in a completely randomized study involving four treatments (groups). Birds in the four groups were fed for 14 weeks with diet 0, 1, 2 or 3. Diet 0 was the basal diet without palm oil, while diets 1, 2 and 3 contained 1, 2 and 3% palm oil obtained by a traditional procedure, respectively. Data were collected on feed intake, egg production, organ weight and biochemical parameters. Results: The results showed that feed intake decreased with an increase in dietary palm oil. Groups D1 (diet 1) and D2 (diet 2) showed high laying rates, low egg weights, low liver weights and a low feed conversion ratio, whereas group D3 (diet 3) had the heaviest eggs and the highest serum total protein concentration. These results might be related to the ability of palm oil to influence feed transit and to improve nutrient digestibility and absorption. Conclusion: Feed containing up to 2% palm oil had a beneficial effect on the egg production performance of laying hens.

  Background and Objective: There has been a search for non-conventional feedstuffs such as maggot meal as a result of scarcity and high cost of fishmeal. The objective of this study was to evaluate the effect of the black soldier fly maggot meal as a protein source on meat quality of broiler chickens. Materials and Methods: A total of 225 broiler chicks (Ross 308) were assigned to five treatment groups of varying dietary inclusion levels of fish and maggot meal; 100% fishmeal and 0% maggot meal (control group) (A0), 75% fishmeal: 25% maggot meal (A25), 50% fishmeal: 50% maggot meal (A50), 25% fishmeal: 75% maggot meal A(75) and 100% maggot meal and 0% fishmeal (A100). At the 57th day, 6 chickens per replicate were randomly selected and slaughtered to evaluate the carcass yield and meat quality. Results: Results showed that there was a reduction of breast water loss in group A100 compared to the other batches (p<0.05). The maggot meal increased the yield and ultimate pH (pHu) of the breast of A100 group (p<0.05). In addition, meat protein levels were also higher in the treated groups than that of the control group (p<0.001). In contrast, thigh yield, abdominal fat and mineral contents were not affected by the dietary inclusion of maggot meal. Conclusion: Broilers fed 100% maggot meal obtained the best meat characteristics. This could be attributed to the high-quality protein contained in the Black Soldier fly (Hermetia illucens) maggot meal. It can be concluded that maggot meal is a non-conventional protein source which can be used as fish meal replacer in broiler diet.

Background and Objective: Appropriate poultry development strategies based on sound knowledge of family poultry practices can benefit households substantially by contributing to food security, women’s empowerment and poverty reduction in developing countries. This study was conducted to obtain information on family poultry practices in Togo. Materials and Methods: This baseline study on family poultry production was carried out in the five regions of Togo. Semi-structured questionnaires were used by trained investigators to collect data through individual interviews in 1,468 households. Results: The results showed that the majority of men in Togo (65.48%) owned poultry and that agriculture is the predominant occupational activity of most (91.35%) poultry farmers. The leading purposes for keeping poultry species were for personal food consumption and income (39.37%). Birds were most often (87.10%) purchased to form the initial poultry flock. Body size was reported by 21.67% of respondents as the trait that most influenced the choice of purchase, followed by a combination of body size and plumage (23.16%). The poultry owned were mainly chickens (n = 50±7), followed by pigeons (n = 31±7) and Guinea fowl (n = 23±5). Cereals were the major feed constituents, particularly maize (95.09%), followed by millet (43.71%), leftovers (35.32%) and sorghum (34.49%). The main sources of water supply for poultry maintenance were wells (36.07%) and boreholes (32.97%). Disease (66.16%), theft (20.17%) and predation (11.54%) were the leading causes of poultry loss. The most common of these diseases were Newcastle disease, coccidiosis, smallpox, bronchitis, salmonellosis, vitamin deficiency and intestinal worms. Approximately 33.15% of respondents reported having provided veterinary care, whereas herbal treatments were used by 46.62% of respondents to prevent or treat diseases in poultry flocks. More than half (55.24%) of the respondents had access to extension services support and 81.38% reported being satisfied with the support provided. Conclusion: Poultry diseases, lack of information and training on management practices are the important constraints in the current status of family poultry production in Togo. The findings obtained from this study are important in determining the resources needed to improve family poultry farming in Togo.
