Thalli is native sheep breed of Thall area of the Punjab, Pakistan. Data on 17030 birth records of 5421 Thalli sheepmaintained at Livestock Experiment Station, Rakh Ghulaman, district Bhakkar during 1975-2004 were utilized in thepresent study with the aim to evaluate the performance of Thalli sheep in Pakistan. The genetic parameter estimation wasperformed using REML procedure by fitting an Individual Animal Model. Birth weight with an average of 4.11±0.82 kg,was significantly affected by year, type of birth, sex and age of the dam but season of birth was an in significant effect onthe birth weight. Weight at 60 and 90-days of age averaged 11.58±3.57 and 14.92±4.56 kg, respectively. These weightswere affected by year and season of birth, birth weight. Type of birth and sex had significant effect on weight at 60 daysof age where as age of the dam had non-significant effect on weight at 60 days of age. Age of the dam significantlyaffected 90-day weight. Sex and type of birth had non-significant effect on 90 days weight. The weaning weight was18.95±4.12 kg and was affected by year and season of birth, sex of lamb. No significant effects of type of birth, birthweight and age of dam on weaning weight were observed. The direct heritability estimate of birth weight was0.067±0.01. The heritability estimates for 60- and 90-day weight were 0.116±0.01 and 0.18±0.01, respectively. Theheritability estimate for weaning weight was 0.03±0.11. Genetic correlation between birth weight and weaning weightwas negatively low with an estimate of 0.045±0.003. The low estimates of heritability for various performance traitsindicated the presence of less additive genetic variance and large environmental variances. Hence improvement in thetraits through selection may be limited MenosThalli is native sheep breed of Thall area of the Punjab, Pakistan.

O objetivo deste trabalho foi avaliar o desempenho de animais, alimentados com lâminas de folhas verdes (LFV) a 4, 8, 12 e 16% do peso vivo por dia, em pastagens de capim-marandu. O experimento foi conduzido em delineamento de blocos ao acaso, com duas repetições. A avaliação do desempenho dos novilhos F1 Nelore e Charolês foi realizada de outubro de 2002 a junho de 2005, nas estações das águas, em Dourados, MS. Cada unidade experimental foi pastejada em regime de pastejo contínuo e carga animal variável, com quatro animais traçadores que permaneceram no experimento dos 15 aos 23 meses de idade, quando foram abatidos. Foi obtido efeito linear entre as ofertas pretendidas e as observadas. A consistência da ingestão de folhas verdes, independentemente das ofertas, foi evidenciada em novilhos fistulados no esôfago. O ganho médio diário apresentou resposta quadrática às ofertas de LFV, com máximo resultado com a oferta de 11,7% do peso vivo. A carga animal e o ganho por hectare apresentaram resposta quadrática negativa ao aumento das ofertas. As ofertas de 8 a 12% do peso vivo permitem que os animais consumam as folhas verdes, com boa qualidade da dieta. |
