This study focused on changes in doe live weight during lactation in West African dwarf (WAD) and Red Sokoto (RS) goats intensively managed within the humid zone of South-western Nigeria. The data analysed was based on 202 weekly records. from  17 lactations of 8 WAD and 9 RS goats from year 2000-2002. Mean live weight for RS does (21.16+0.34 kg) was higher (P<0.001) than the estimate (18.15+0.34 kg) for WAD does. Live weight decreased (P>0.05) from parturition up to fourth week and increased (P> 0.05) thereafter till the 12th week of lactation. There was no significant interaction between breed and week of lactation. Cumulative mean weight changes of 0.16+4119 kg for WAD and 0.38+0.22 kg for RS were not significantly different, Does had higher (P<0.001) body weights during the late- wet and early-dry seasons than during late-thy and early-wet seasons.. Live weight increased .significantly (P<0.001) with parity of doe, the trend being maintained with regards to cumulative weight change. Does that suckled male kids were less superior in body weights. This was reflected by a negative cumulative weight change. Live weight was positively con-elated with milk yield (rp = 0.24; P<0.05,4 estimated at 270.61+13.48 ml and 281.98+ 13. 17 ml respectively for RS and WAD goats (P>0.05). Corresponding values for milk off-take were (.14.09+3.64 and 16,45+3.56 ml; P>0.05), Milk off-take was lowly correlated with live weight (rp= 0_06; P>0.05) while its relationship with milk yield was positive and significant (rp= 0.40: P<0.001).

An experiment was conducted to determine the growth performance and carcass characteristics of West African Dwarf bucks fed different types of processed Panicum maximum. Twelve West African Dwarf bucks aged between 6 and 8 months with initial mean weight of 7.26 kg were intensively managed for 56 days. The experimental diets are wilted Panicum maximum, fresh Panicum maximum, ensiled Panicum maximum and Panicum maximum Hay designated as T1, T2, T3, and T4, respectively. The results revealed that goats placed on wilted Panicum maximum (T1) (135.18g/day) and hay, (T4) (139.29g/day) were similar in respect to concentrate intake. Forage intake showed significant (P<0.05) differences. Goats fed wilted Panicum (T1) (607.78g/day) and fresh Panicum maximum (T2) (634.46g/day) had similar intake but differed from goats placed on ensiled Panicum maximum (T3) and hay Panicum maximum (T4). Daily dry matter intake (DMI) differed (P<0.05) significantly among treatments. Total daily feed intake of goats on wilted Panicum maximum (T1) (42.96g/day) and fresh Panicum maximum (T2) (759.80g/day) were similar and differed from total daily feed intake of goats placed on ensiled Panicum maximum(564.28g/day) and Hay Panicum maximum484g/day. Goats fed wilted Panicum maximum produced higher value of live weight which did not differ (P>0.05) from other treatments.Bucks on fresh Panicum maximum (T2) had higher value of bled weight (7.40kg) but did not significantly differ (P>0.05). Heavier dressed weight (35.62) was recorded by goats fed wilted Panicum maximum (T1) but did not significantly differ (P>0.05) from other treatments. Dressing percentages, thigh, loin, internal organs and bone to lean ratio were not significantly different (P>0.05) from each other. The use of Panicum maximum in any form has no effect on conversion of forage into meat and formation of any part.

Crude protein is essentially needed for ruminants but expensive to supply. Mucuna puriens is a high yielding domesticated legume. When the legume is strategically combined with a fibre source, it will make a good diet for ruminants. Thus, a study was carried out to assess the effect of ensiling mucuna with maize forage on performance of rams. In the study, rams were fed silage combinations of Maize Forage (MF) and Mucuna pruriens foliage (MPF). Downy mildew and streak resistant (DMR-SR) yellow variety maize was planted and harvested as MF at six weeks of growth and ensiled with MPF at four levels : 1:0, 3:1, 1:1 and 1:3 for 21 days. All the four silages were fed to 20 WAD rams (12.00±0.25 Kg) in a completely randomised design for 105 days. Proximate composition of the silages, apparent nutrient digestibility of silages in WAD rams, feed intake and weight changes were determined using standard procedures, while feed conversion ratio was computed using standard procedures. Data obtained were analysed using descriptive statistics and ANOVA at α0.05...The dry matter (DM) was significantly higher in T1 (25.65±0.62) and T2 (23.48±0.47) than T3 (21.80±0.41) and T4 (21.57±0.40). The crude protein (CP) was highest in T4 (13.0±0.6) and least in T1 (8.0±0.2). The crude fibre was significantly higher in T1 (26.4±2.6) and T2 (26.2±2.0) than T3 (24.0±1.8) and T4 (21.6±0.9). Apparent digestibility of neutral detergent fibre (NDF) was highest in T2 (59.2±1.7) and least in T4 (37.7±1.9), while percentage nitrogen retention was significantly higher in T2 (43.2±3.8) and lower in T1 (20.0±4.3). The FCR for rams fed T2 was significantly lower (8.84±1.2) than T1 (9.76±0.80), T3 (9.60 ±0.60) and T4 (11.50±0.90) Ensiling maize forage with Mucuna pruriens foliage at 3:1 enhanced nutrient digestibility and growth performance in West African dwarf rams without any deleterious effect.

Twelve West African Dwarf sheep, comprising four ewes in each of the Parities 1, 2 and 3, were used to determine the effect of parity on udder traits during lactation, milk yield and composition. Udder length, udder width, udder circumference, udder volume, teat length, teat width, teat circumference, distance between the teats and teat height from the ground of sheep were measured in centimetres (cm) weekly for 12 weeks of lactation, commencing from Day 4 postpartum. Parity highly influenced (P < 0.05) udder traits, except udder volume (P > 0.05). The udder length, width and circumference were higher (P < 0.05) in Parity-3 ewes than Parity-1 and -2 ewes. A similar trend was shown for teat length, width and circumference. Parity had no effect (P > 0.05) on udder volume, but significantly (P > 0.05) affected distance between the teats and teat height from the ground. With the exception of udder volume, all traits peaked by the 3rd week of lactation, and gradually declined thereafter. Milk yield and milk weight peaked by the 3rd week postpartum and these were higher for ewes in Parity 3. Milk yield and milk weight declined faster in ewes in Parities 1 and 2 than they did in Parity-3 ewes (P < 0.05) as lactation length increased. In regard to milk composition, moisture, protein and fat, but not total solid, solid-not-fat and lactose, were greater (P < 0.05) in Parity-3 ewes both at peak milk yield (3rd week of lactation) and end of lactation. From these findings, we conclude that parity type plays a significant role in influencing udder traits, milk yield and milk quality in ewes.
