“…The performance of the female kids (Table 3) revealed (1087.50 ± 106.50). Birth weight of a kid is a reproductive trait that could be influenced by such factors as body weight and condition score of dam, nutritional status, type of birth, sex and season of the year (Cassard et al, 1956). The WAD dams were well adapted to the rearing environment and may have utilized the concentrate -fodder based ration better.…”

A total of 56 kids produced from four breeding goat units consisting of pure Red Sokoto (RS ×RS), pure West African Dwarf (WAD × WAD), main cross (RS × WAD), and reciprocal cross (WAD × RS) were used to investigate performance and cost benefit of producing progenies of these indigenous goat breeds in a rain forest zone of South Eastern Nigeria. The experimental design was a completely randomized design with genetic group as the factor of interest. Data obtained showed that at birth, the male RS × RS kids weighed significantly (P<0.05) highest (1840.0 ± 230.98 g), followed by WAD × RS (1430 ± 144.36 g), RS × WAD (1371.00 ± 56.54 g) while the WAD x WAD kids had the lowest birth weight (1150.00 ± 39.36 g). However, the RS × AD female kids, at birth weighed significantly highest (1500 ± 54.10 g), followed by the RS × RS (1328.50 ± 98.69g), WAD × RS (1312.50 ± 17.81 g) and WAD × WAD (1087.50 ± 106.80 g). The male and female kids of the RS × WAD had improved body weight and the linear body measurements such as body length, height-at-withers and heart girth. They also had a higher average daily gain (46.03 ± 1.41 g/day) and better feed conversion ratio (5.38 ± 0.27) than the RS x WAD and WAD x WAD goats. This genetic group had the lowest cost of production (N953.40 ± 10.21) and as such the highest gross margin (N2111.06 ± 21.7). They appear more promising hybrid goats for commercial meat goat production in the rainforest zone of South Eastern Nigeria.

Change of skeletal dimensions during growth in sheep: the effect of nutrition

1989

S U M M A R YMeasurements of skeletal size were made at 2-3-month intervals on 30 Border Leicester x Merino castrate male (wether) sheep between 2 and 27 months of age. Fifteen sheep were fed ad libitum on a high-quality diet and the other 15 half the average amount consumed by the first group, age for age. The ad libitum group grew faster and were larger in all body dimensions on each occasion, except for leg length at 27 months which showed no statistical difference between groups. When the groups were compared over the live-weight range common to both (16-44 kg) the unrationed animals were consistently wider at the shoulders but smaller in leg and chest dimensions.The relationship between each body component and age is described by a Mitscherlich equation and the relationship with live weight by a linear equation in which both variables are log transformed. Separate relationships were determined for each sheep and tested for differences within and between groups.

Effect of feeding dried beet pulp on growth rate of Awassi sheep

et al. 1968

SUMMARYGroups of Awassi lambs, aged 7–13 months at start of the trial, were fed for 100 days on four different rations. A ‘control’ ration contained ground barley: the others contained different proportions of dried sugar-beet pulp, and no barley.Male lambs were initially heavier, and gave better weight gains than the females. Groups on beet pulp grew better than the ‘control’. The most economical weight gains were obtained in the group in which beet pulp constituted 40 % of the ‘concentrate’ portion of the diet.
