Oral administration of Gongronema latifolia leaf meal: Implications on carcass and haematological profile of broiler finishers raised in the humid tropics

An experiment was conducted to determine the effect of Gongronema latifolia leaf extract (GLLE) on carcass characteristics and haematological indices of broiler finisher birds. A total of 120 four weeks old Marshall Strain commercial broilers were randomly selected and assigned to four experimental treatments namely: W- water only, WV- water + vitalyte, GL30- water + 30 ml GLLE and GL60- water + 60 ml GLLE. At the end of four weeks, nine birds were randomly selected from each treatment and humanely slaughtered for carcass, organ evaluation and haematological studies. The live weight, dressed weight and the relative weights of the thigh, drumstick and breast of the birds were better (P < 0.05) for birds on the GLLE. The relative weights of the eviscerated carcass, head, neck and organs were not affected by the treatments. The haematological characteristics of the birds showed significant differences (P < 0.05) in packed cell volume, red blood cell counts and white blood cell counts in favour of birds on WV, GL30 and GL60. The study showed that GLLE had nutritional benefits on carcass and organ quality of birds in spite of its antinutritional content. Therefore, it can be used as a nutrient supplement in poultry production.Keyword: Gongronema latifolia, carcass, organs, vitamins, minerals, strain, haematology

Neonatal mortality of pigs in Nsukka, Southeast Nigeria

This study was conducted to investigate the causes of neonatal mortality among pig farms in Nsukka  Local Government area of Enugu State, Nigeria. Forty (40) pig farms in the study area were randomly  selected and used for the 20 weeks study duration. One week post partum was considered as the  neonatal period. A total of 124 pregnant sows and 924 piglets farrowed during the study period were used. Data were obtained from farm visitations/physical observations, farm records, oral interviews and structured questionnaires. Feed samples were analyzed for their proximate contents. Pregnant pigs were weighed prior, during and few days after farrowing, while piglets were weighed within seven days after farrowing. Necropsy and bacteriological examinations of samples of feed, maternal and diseased or dying neonates were also carried out. Results showed that mean litter size, piglet weight at birth and daily weight gain were 7.45 ± 0.02, 1.01 ± 0.03 and 0.21 ± 0.01 kg, respectively. 164 (17.75%) of total piglets farrowed died within the first week of life (neonatal period), whereas 144 (87.80%) of this number died within the first five days. In addition, 48 (29.27%) were over laid, 30 (18.29%) died of scouring caused by Escherichia coli and Salmonella organisms, 30 (18.29%) died of hypoglycaemia. On the other hand, 20 (12.20%) piglets were cannibalized by older pigs and or their dams, 16 (9.75%) were trapped within the drainage, 12 piglets (7.32%) died of chilling, while eight (4.88%) died of unknown causes. Other contributory factors include inappropriate farm structures, absence or inadequate farm records, nutritional imbalance, improper management practices and inadequate veterinary services. It was concluded that neonatal mortality is a major impediment to optimum profit making from swine enterprise in Nsukka, South Eastern Nigeria.Key words: Neonatal, piglets, mortality, Nsukka urban, Nigeria, sow performance
