Abstract

An Investigation on the viability and growth characteristics of Walliser-Schwarzhals and Walliser-Schwarzhals x Hairy Goat breeds

Abstract

The main animal material of this ~nvestigation
consisted of 7 Walliser, 17 Hairy goat and 31 WalliserSchwarzhals
x Hairy goat (F1) crossbreed. Using Walliser and
other genotypes, 7 Walliser, 21 F1 and 32 G1 kids were obtained.
In this study, viability and growth characteristics of
these genotypes have been investigated.
In the Walliser, F 1 and G 1 kids, the percentage of viability
was 71, 42%, 79,16% and 90,62% respectively.
In the Walliser, F1 and G1 average birth weights were determined
as 3.66 ±0.20 kg, 3.46 ± 0.11 kg and 3.54 ±0.09 kg
respectively. As far as the birth weight is concerned, the difference
between genotypes was not statisticaly significant.
In the Walliser, F 1 and G 1 body weights at 12 week were
11.48 ±1.07 kg, 13.02 ± 0.58 kg and 14.58 ± 0.45 kg respectively.
The difference between values was found to be significant
( P < 0.05) and this variation ·was due to the difference
between Walliser and G 1·
There was a significant difference between birth types,
namely, single kids had more birth weights than twins. An important
difference was not found between the sexes.
The average daily gain of the body weight in Waliser was
0.094 ± 0.012 kg, in F1, 0.113 ± 0.007 kg and in G1 0.131 ±
0.005.
Cross-breeds gave far better results than pure breeds
with regard to daily average gain of the body weight and 12
week body weight. lt was concluded that using Walliser goats
as improvers for the hairy goats was more appropriate.
