The aim of the study was to investigate the effects of supplementation during mating and at late pregnancy on ewes body condition score and lambs growth rate in the dry season. A total of 341 ewes were selected during mating season. The animals were randomly assigned to four groups. Group one was used as a control, the second, third and fourth group were supplemented with rations containing groundnut cake (GNC), groundnut cake and molasses (GNC-M) and Roselle seeds and molasses (RM). All ewes in the three supplemented groups were flushed and steamed-up, while the control group received no supplements. Ewes were offered 450 g / head of the ration every three days at the watering periods and the rams 600 g / head for three days. Body condition score (BCS) of ewes were estimated in breeding, mid pregnancy and lambing period. The lambs were weighed at birth, and each two weeks till day 120 post-partum. The results obtained indicated that, supplementation improved the BCS compared with farmer practice. The study indicated that, the pre-partum supplementation of the dams increased lamb daily growth rate before weaning. Source

This study evaluated the effect of diet supplementation on body condition score (BCS) and reproductive performance of Sudanese Desert ewes in comparison with farmer practice without any feed supplementation. A total of 341 ewes aged 1-6 years, were maintained in four groups of similar initial body weight and age. Group 1 (60 ewes) was the control (no feed supplementation). Groups 2 to 4 (92, 97 and 92 ewes, respectively) received feed supplementation containing local available feed resources in amounts of 0.45 kg every three days at watering time during two periods (45 days mating period and 45 days before lambing). Results indicated supplementation improved (P>0.05) BCS, lambing rate, fertility rate, prolificacy, fecundity, pregnancy, weaning rate and decreased abortion rate. Ewes of first parity number had higher (P>0.05) BCS. There were no effects of birth type, sex of lamb and parity number on gestation days. The reproductive performance was improved (P>0.05) as ewe's age increased. This study indicated that a moderate diet supplementation, every three days, is an efficient strategy to reduce nutritional stress in Sudanese desert ewes and increase their reproductive performance.

Supplementary feeding experiment was carried out with desert ewes prior to late pregnancy days and during lactation period at Agricultural Research Station, El-Obeid, North Kordofan, Sudan. The aim of the study was to investigate the effect of supplementation on body weight of lactating ewes and their lambs in the dry season. The ewes were allocated to one of four treatment groups, one group was the control as in farmer practice and the other three groups were fed with rations composed from ground nut cake, sorghum, molasses and Roselle seeds (Hibiscus sabdariffa). The results indicated that, supplementation in late pregnancy and during early lactation had significant effect (P < 0.05) on body weight of dams and their lambs. Body weights were highest for the supplemented dams compared with the control group. Lambs suckling on control dams recorded lowest weights, also supplementary feeding improved lamb weights at birth and the 60 day post-partum. Source

Three local legumes seeds produced in Sudan were subjected in their two preliminary forms (whole and decorticated seeds) to different traditional processing and then analyzed for their composition of nutrients, minerals and amino acids. All seeds were found as good source of protein and digestible carbohydrate which support their supplementation approach in poultry diets. They show as well substantial quantities of minerals with an abundance of potassium and phosphorus. Amino acid analysis revealed high lysine, leucine, phenylalanine and arginine while sulfur-containing amino acids methionine and cystine were found deficient. Decortications and its further following processing were of worse effect mainly upon mineral contents, in addition to their impact on somewhat wastefulness of nutrient components owing to the inefficiency of dehulling, besides its cost effects. Roasting in spite of its negligible effects was inferior to both of germination and boiling of pre-soaked whole seeds with regard to amino acids. Boiling of presoaked whole seeds was found appropriate to all studied legumes while the 72 hour germination of presoaked seeds was superior to boiling for L purpureus seeds. © Asian Network for Scientific Information, 2010.

L. purpureus is considered to substitute some of conventional plant protein sources in poultry diets. In 12 weeks feeding trial the processed L. purpureus seeds were investigated for its impacts on laying performance, egg quality and serum constituents of Hisex White hens. Diets contain 0, 5, 10, 15 and 20% L. purpureus were allotted randomly following completely randomized design to 25 units of three birds each. Hen day egg production, egg weight, egg mass, FCR and weight gains were significantly (p<0.01) high up to 10% L. purpureus. Shell percentage and thickness were significantly (p<0.05) high in control and 20% L. purpureus groups. 15 and 20% L. purpureus dietary groups were of high egg albumin index and percentage. The utmost (p<0.05) yolk index and percentage were shown in 15 and 10% L. purpureus groups, respectively. Comparable high Haugh units were shown in different treatment groups. 15% L. purpureus groups, recorded significant (p<0.01) high serum total protein and globulin. All L. purpureus treatment groups were of significant (p<0.05) low serum albumin. Serum glucose was significantly (p<0.01) lowered in L. purpureus groups, while serum cholesterol was insignificantly (p>0.05) reduced due to L. purpureus inclusion. The 20 and 10% L. purpureus groups when compared to control were found of low serum P and Ca, respectively. In conclusion, up to 10% dietary inclusion of L. purpureus is appropriate to provide similar laying performance as the standard layers diet. © Asian Network for Scientific Information, 2012. Source
