Arachis Hypogaea L

In Ghana, peanut (Arachis hypogaea L.) grain and fodder serve as important sources of protein for human and livestock nutrition, respectively. Experiments were conducted in four farming communities to determine the effects of planting annual peanut at four inter-row spacings of 30, 45, 65 and 75 cm on grain and fodder yields (experiment I), growth performance and manure quality (experiment II), and in situ digestibility (experiment III) of Djallonké sheep fed fodder from these plant spacings. Planting peanut at 30 cm inter-row spacing dually increased grain and fodder yields compared to planting at 60, and 75 cm. Peanut fodder from 30 cm inter-row spacing also had comparatively higher concentration of crude protein and lower concentrations of acid detergent fiber and acid detergent lignin, resulting in significant improvements in dry matter digestibility at 48 h and superior average daily weight gain of sheep. The concentration of N excreted in the manure of sheep fed the 30 cm fodder was greater than those fed peanut grown at 60, and 75 cm inter-row spacing. Planting peanut at an inter-row spacing of 30 cm therefore gave dual benefits of increasing grain and fodder yields as well as increasing the digestibility and growth performance of sheep fed peanut fodder as a supplementary diet to natural pasture for 70 days. Higher concentration of N in the manure of sheep fed 30 cm fodder could have additional benefits of improving soil fertility in smallholder farming systems where inorganic fertilizers are expensive and inaccessible to farmers.

The study was carried out on two different genetic groups of pig viz. Duroc and Hampshire maintained at pig breeding farm of National Research Centre on Pig, Guwahati. Effect of different genetic group and non-genetic factors (year and season of farrowing and parity) were estimated by least squares analysis of variance for different litter production, weight and pre weaning growth rate. Genetic group and parity revealed highly significant (P less than 0.01) effect on all the traits under study. However, effect of year and season of birth was non significant in most of the cases. The pre weaning mortality of Hampshire pigs was found to be less than Duroc. The performance of litter production and weight traits of Hampshire pigs were found to be better than Duroc pigs in the farm.

Birth weight records of 738 Kedah Kelantan (KK) calves and 30 records on their 3 and 6 months body weight were obtained from Pusat Ternakan Haiwan Pantai Timur (PTHPT), Tanah Merah, Kelantan during the period of 2010- 2012. Data for this study were collected to identify non-genetic factors that affect birth weight and to observe growth performance of KK calves. The non- genetic factors that encompassed in this study were sex of calves, year of birth, season of birth and parity of dam. Growth performance was divided into two periods which were ADG 1 (Average Daily Gain) (birth to 3 month) and ADG 2 (3 to 6 month).The study revealed that effect of sex of calves and year of birth were highly significant (p<0.01) on birth weight of KK calves. Birth weight of male and female calves averaged at 14.27 kg and 13.50±0.058 kg respectively. Effect of season of birth and parity of dam were insignificant (p>0.05) on birth weight of KK calves. Growth performance of KK calves was found to be 338.148±15.565 g/day and 247.407±45.254 g/day for ADG 1 (birth to 3 month) and ADG 2 (3 to 6 month) respectively. Little but significant improvement in birth weight of calves over the years might be partly due to genetic selection of breeding bulls.
