Linear dimensions of WAD lambs and kids were compared under traditional management system from birth to weaning age of 3 months. At hirth, male and female lambs were comparable to their kid counter parts in body length (BL) and Height-at-withers (HW) but inferior to kids in Heart Girth (HG),, Mean HG for lambs at birth was 23.09cm while that of kid was 26.62cm. At 3 months, mean HG for lambs was 49.40cm while that of kids was 46.24cm. Birth type had significant effects  (P<0.05) on linear dimensions at birth and weaning. For both species, linear dimensions increased with increase in birth and weaning weights. The superiority of WAD lambs is body dimensions Compared to WAD kids is indicative of better frame size in lambs at post weaning age.

The pre weaning growth performance of piglets from four different cross bred dams mated back to their native parents was studied in the Breeding and Research Farm of Ebonyi State University, Abakaliki. Parameters like body weight, weight gain, feed intake and feed efficiency as well as linear body measurements of body length, heart girth and height  at withers were taken and observed for growth between birth and weaning age of eight weeks. Results Results indicated significant differences (P<0.05) between the main backcross N x (N x LR) and the three other genotypes of N x (N x LW), N x (LR x N) and N x (LW x N) in all parameters. The mean birth weight of the progenies ranged from 1.00±0.60 to 1.60±5kg while the weaning weights were 10.5±0.4 to 16.0±1.0kg respectively. Results further revealed that body weight at weaning correlated responsively with all parameters and these include body length (r=0.858), heart girth (r= 0.446) and height at the withers (r= 0.946). Similarly, body length has a positive correlation with heart girth (r= 0.477) and height at the withers (r= 0.827) whereas hear girth correlated positively with the height at the withers (r= 0.494). Similar trend were obtained in the regression of each of the body measurements on the other in which bodyweight changes depended more on that of body length (0.86) than on heart girth (0.45). Judging from the observed variations existing among the piglets resulting from differnt crossbreed dams in their pre-weaning growth performance, maternal rather than paternal influences appeared to be more important in the traits studied.

One hundred and ninety two records were taken weekly for twenty four (24) weeks from West African Dwarf (WD), the Yankasa (YN) and the West African Dwarf X Yankasa crossbred (XB) sheep. The traits evaluated were milk yield (MK), linear body measurements (LB) such as height at withers, (HT), body length (BL), heart girth (HG), shoulder width (SW), Tail length (TA), Neck length (NL), Neck circumference (NC), Face length (FA), Hind leg length (HL), Foreleg length (FL), Face length (FA), Ear length (EA), Head width (HW) and Rump height (RH) together with the following Udder dimensions (UD): Udder circumference (UC), Teat length (TL) and Teat circumference (TC). There was significant (P<0.05) influence of genotype on MK, WHT, HT, BL, TA, FL, HL, FA, EA and RH. The WD ewes produced more milk than either the YN or XB enes. Average daily milk yield (ml) was 122.25, 90.88 ana 108.8. The YN genotype was superior in all LBs except SW and NC than the WD and XB in the three genotypes. Height at withers was 59.08, 69.21 and 61.81 cm; BL 48.54, 55.08 and 54.49 cm and RH 62.88, 75.11 and 68.46 cm for WD, YN and XB enes respectively. Since milk offtake is related to body weight and some linear body measurements, selection for WT, HG, SW, NL NC, UC and TL in WD ewes could lead to higher milk and mutton production.

During suckling, goat kids exhibit different kinds of behavior which could be germane to their general performance. The objective of this study was to determine suckling behaviour of West African dwarf (WAD) goat kids with respect to some behavioural measurements. A total number of 21 WAD does comprising of 1st and 2nd parity with live weight range of 9.5kg-16.5kg with a total of 26 kids (12males and 14females) in a small holder dairy goat were used. Data on suckling behaviour (suckling bout, duration of suckling and number of butts during suckling) was monitored to investigate the effect of birth type (singleton and twin) and kid sex (male and female). Behaviours were observed twice/day i.e. in the morning (7:00-8.30 am) and evening (4:30-6:00pm), 2 days/week starting from the 2nd week after kidding for 7 weeks. Suckling bout, duration of suckling and number of butts during suckling was greater in twin than in singleton. Kid sex had no significant effect on all behavioural parameters monitored. However, significant positive correlations were observed between suckling bout and number of butts during suckling, between suckling bouts and duration of suckling and between duration of suckling and number of butts during suckling. In conclusion, suckling behaviours in WAD kids were dependent on the birth type and not sex of the kids.

Central performance testing of young rams has been conducted in Finland since 1975, in 1985—87 indoors as combined phenotype and 1/2-sib tests, which are the subject of this study. There were 100 individual boxes available, of which ca. 90 were annually used for Finnsheep (F). The rams were fed on concentrate diet (13.5 % DCP) ad lib. + hay. The test period was from 60 to 150 days of age. Feed intake (FI) was recorded daily, live weights (LW) fortnightly. At the end, MLD-areas were ultrasonically scanned, fleeces weighed, some linear body measurements taken, and fleshiness and wool quality scored. A total of 276 F rams were tested. They were progeny of 85 sires (2—4 half-brothers/sire). The means for all rams (30 selected rams) were: birth type 3.19 (3.18), rearing type 2.93 (3.01), age at start 64.3 (63.7) days, 60-day LW 19.5 (19.5) kg, 150-day LW 45.1 (47.6) kg, ADG 284 (312) g/d, FI 1.28 (1.34) kg/d, FE 4.49 (4.29) kg/kg gain, MLD-area 8.83 (9.63) cm2. There was considerable variation in the important traits (ADG, FI, FE, MLD-area), in spite of preselection. The phenotypic correlations of ADG with 150-d. LW, FI, Fl/kg gain and MLD-area were .61, .57, —.63 and .37, resp. (PC.001). Those of 150-d.LW with the last three traits were .59, —.15 NS and 0.44, resp.(P< .001). Selection for ADG, 150-d. LW, Fl/kg gain and MLD area in the performance test appeared to improve the value of offspring for meat production in F.

There are three main breeds of goat in Nigeria: The West African Dwarf (WAD), the Red Sokoto and the Sahel. Goats are renowned for their hardiness and can survive in most environments. The goats sampling was carried out from farms and markets across different states in Nigeria, according to the geographical distribution of the breeds published by Blench (1999). This experiment was carried out to analyse morphological variability among Nigerian goats. A total of 318 goats spread across the three Nigerian breeds were used in the following populations (57 Sahel, 187 Red Sokoto and 137 West African Dwarf). Data were collected on body weight, linear body measurements and heat tolerance traits and were subjected to analysis of variance using the fixed effects of breed, sex and location. Results showed that breed, sex and location significantly (P<0.05) affected all the linear body measurements and heat tolerance traits. The Sahel breed had the highest values in most of the measured traits compared to the West African Dwarf and the Red Sokoto breeds of goat. It was observed that goats from the northern part of Nigeria were heavier than their southern counterparts, and this can be likened to their genetic makeup and the extent of its interaction with the environment. The results of the study confirmed the population structure of Nigerian goat breeds and showed that they possess enough diversity to enhance genetic improvement for higher survival and productivity.
