  The study evaluated the nutritive value of seeds of wild Senna obtusifolia plants as an alternative plant protein source in livestock diets. Proximate composition results showed high dry matter (92.50%), crude protein (29.54%) and crude fiber (10.18%), but low ether extract, nitrogen free extract, ash and calorific values. The vitamin content results showed poor vitamins B2 , B1, C and A but the seeds were rich in vitamin B3 (1.85 mg/100 g) values compared to other seeds. The seeds were also abundant in calcium (960 mg/100 g), potassium (1,200 mg/100 g), phosphorus (810 mg/100 g), sodium (600 mg/100 g), magnesium (640 mg/100 g), iron (234.60 mg/100 g), zinc (53.12 mg/100 g) and copper (10.48 mg/100 g) but low in molybdenum, cobalt, chromium, selenium, sulphur and fluorine. The amino acid profile reveals a high concentration of leucine (7.60 g/100 g protein), histidine (2.11 g/100 g protein), proline (2.33 g/100 g protein) and glycine (4.11 g/100 g protein) while the rest of the amino acids were of low concentration in the raw seed. The concentration of anti-nutrients in the legume seeds recorded high values (260, 185, 388.50 and 83.25 mg/100 g) for alkaloid, saponin, tannin and oxalate respectively, while phytate, hydrocyanic acid and phytohaemaglutinin levels were low. The high level of most anti-nutrients indicates the potential for interfering with the utilization of the nutrients by the animals. This therefore, creates a need for detoxification of the seeds through processing before using in livestock feeds.

  The effects of replacing fish waste meal with shrimp waste meal at five levels (0, 25, 50, 75 and 100%) on broiler chicken performance was studied in a feeding trial involving 204 Anak breed of day-old. Chicks fed iso-nitrogenous and iso-caloric diets (23%) crude protein and 2800 kcal (ME)/KG and 20% crude protein and 3000 kcal (ME) kg-1 for the starter and finisher phases, respectively). The birds were shared into five treatment groups and one control of 34 birds each. All the birds were fed and watered ad libitum throughout the 56 days experimental period. Daily feed intake and weekly weight gain were recorded. Average weekly feed intake was not significant (p>0.05). The 0% replacement level had the best (p<0.05) weight gain (212.20 g±9.73 and 520-439±28.61 for the starter and finisher phases respectively), while the 100% level had the least (p<0.05) weight gain in both phases. The percent liver, gizzard, abdominal fat, drumsticks and breast were significantly (p<0.05) affected by treatment application. Feed conversion ratio was best (p<0.05) at the 0% level (i.e 1.67±0.12) for the combined phase while the poorest value was recorded for the 100% level in the combined phase. The replacement of fish waste meal with shrimp waste meal was directly proportional to the feed consumption rate, feed conversion ratio and organ weights but indirectly proportional to weight gain. Findings suggest that the 0%, control and 25% level of replacement of fish waste meal with shrimp waste meal were optimum for broiler chicken performance.

  Background and Objective: Synthetic and semi-synthetic antibiotics as growth promoters are widely used in poultry production with some positive and negative effects and this has redirected research to natural antimicrobial products and plant leaves like neem leaf meal. The relevance of neem leaf meal as a growth promoter is due to its useful medicinal properties such as antibacterial, antiviral, antifungal, antiprotozoal, hepatoprotective, immunomodulatory and other peculiarities. This study therefore evaluated the effect of dietary inclusion of neem leaf meal (NLM) on the growth performance and carcass characteristics of broiler chickens. Materials and Methods: The feeding trial lasted for 8 weeks and a total of 192 day-old broiler chicks were used. The chicks were randomly allotted to four dietary treatments of 48 birds per treatment and replicated thrice with 16 birds per replicate in a completely randomized design (CRD). Four iso-caloric and iso-nitrogenous diets were formulated containing NLM at inclusion levels 0, 2.5, 5 and 7.5% for T1, T2, T3 and T4, respectively. Appropriate data on growth performance and carcass characteristics were determined and results subjected to one-way ANOVA accordingly. Results: Results showed the proximate composition of the NLM as 94 DM, 22.4 CP, 20.5 CF, 3 EE, 12.2 ash and 41.9% NFE. At the starter phase, performance traits like the average final weight, total weight gain, daily weight gain and feed conversion ratio were not significantly (p>0.05) affected by dietary treatments, with the exception of the average daily feed intake was significantly (p<0.05) different. All the parameters reduced in value across dietary treatments as the inclusion levels of NLM increased. At the finisher phase, the average total weight gain, daily weight gain, daily feed intake and FCR were significantly (p<0.05) influenced by dietary treatments. Generally, birds fed NLM beyond 2.5% inclusion level recorded poorer growth performance characteristics compared with the lower level (2.5%) and control diet. Results for carcass characteristics, cut-up parts and internal organs of broiler chickens fed NLM showed no significant (p>0.05) differences between treatments, implying that NLM might not adverse effect on the carcass characteristics. Conclusion: The study concluded that 2.5% NLM can be included in diets meant for broiler chickens without fear of compromising growth performance and carcass characteristics.
