“…The use of milk replacers has been studied in lambs (P eters and H eaney 1974; P enning et al 1977), calves (A be et al 1981) and young goats (S anz S ampelayo et al 1990). Generally, young pre‐ruminant animals can utilize nutrients from the milk replacer as efficiently as other mammals and consequently artificial rearing can be carried out without any specific problems (S anz S ampelayo et al 1990; R ojas et al 1994).…”

Summary In the present work the carcass composition and fatty acid composition of the fat deposits of young Colmenarcña and Rubia del Molar male lambs fed with natural milk and with commercial milk replacer were studied. The daily gain during the late phase of feeding (15‐30 days) was higher in the animals that were reared artificially than in those fed by their mothers (310 versus 245 g/day, p < 0.001). Carcass characteristics and dissected shoulder tissues were not markedly affected by dietary treatment. Lambs receiving sheep milk had higher concentration of C15: 0, C17: 0 and total saturated fatty acids than groups receiving milk replacer (p = 0.001). A higher rumen, reticulum, omasum, abomasum and small intestine development was also found in lambs fed by their mothers compared with those fed milk replacers (p < 0.05). The results from this experiment suggest that lambs artificially reared have a lower rumen functionality and might be slaughtered at higher weights without a concomitant loss of meat quality. Zusammenfassung Einfluß des Tränksystems auf Wachstum, Körperzusammensetzung und Entwicklung des Verdauungskanals bei Lämmern Je 10 neugeborene Lämmer der Rassen Colmenareña und Rubia del Molar konnten über 30 Tage entweder an ihrer Mutter saugen oder sie wurden mit einem Milchaustauscher ernährt. Die Anfangsgewichte betrugen im Mittel 3,4 kg, die Endgewichte 10,5 kg/Lamm. Im Versuchsabschnitt vom 15.–30. Tag betrugen die Tageszunahmen der an der Mutter saugenden Lämmer 245 g und die der mit Milchaustauscher ernährten Tiere 310 g (p < 0.001). Die Körperzusammensetzung war durch die Tränke nicht signifikant beeinflußt. Die mit Muttermilch ernährten Lämmer wiesen höhere Konzentrationen an C15:0, C17:0 und insgesamt an gesättigten Fettsäuren auf als bei Einsatz von Milchaustauschern. Die saugenden Lämmer wiesen ein höheres Gewicht des vollen Magen‐Darmtraktes auf (1599 bzw. 1265 g). Auch die Leergewichte von Pansen, Reticulum, Omasum, Abomasum und Dünndarm waren bei den an der Mutter saugenden Lämmern signifikant höher als bei den mit Milchaustauschern ernährten Tieren. Infolge der geringen Pansenentwicklung wird geschlußfolgert, daß die mit Milchaustauschern ernährten Lämmer ohne Beeinflussung der Fleischqualität mit einem höheren Gewicht geschlachtet werden können.

“…The protein source of milk replacers is often milk protein concentrates and whey proteins (Beserra et al, 2003). The casein content of milk replacers is lower than in goat milk, which may produce some problems with curd formation in the kid abomasum (Sanz Sampelayo et al, 1990). Hashimoto et al (2007) included soy as a protein source in milk replacers, but the effects on growth and meat quality are yet to be clearly defined.…”

Goat kids in intensive dairy goat farms are usually reared on milk replacers, due to farmers' desire to use all the milk for commercial purposes or cheese-making. In this chapter, growth, carcass and meat quality characteristics of goat kids fed milk replacers are studied in depth in comparison with kids reared naturally on goat milk. 14.3. Goat kid growth under goat milk or milk replacer diets The goat is an important source of meat in Africa, Asia and the Far East. It is now emerging as an alternative and attractive source of meat in other parts of the world. With milk goat breeds, kids are usually reared on milk replacers, so that all milk produced can be sold as fresh milk or processed into dairy products as cheese or yogurt. Young kids have to be routinely fed milk replacers. 14.3.1. Growth curves Growth in farm animals in general, and goats in particular, is usually represented by an exponential curve. However, observations during the first month of life have shown a better statistical fit to a linear regression (Argüello et al., 2004). Growth curves of kids reared during the first month of life under NS, ALAR and RAR systems are shown in Fig. 14.1 (Argüello et al., 2004). NS kids have a significantly higher average daily gain (ADG) than ALAR and RAR kids (Pérez et al., 2001; Argüello et al., 2004), and ALAR kids have a significantly higher ADG than RAR kids (Argüello et al. 2004). The higher ADG in NS kids is caused by the higher digestibility of components in goat milk than in milk replacers because the goat milk curd stays longer in the abomasum than the milk replacer curd (Sanz Sampelayo et al., 1990; Baumrucker and Blum, 1993). Baumrucker and Blum (1993) found that dams' milk has a growth promoter that is not present in milk replacers, which could explain the higher ADG in NS kids. NS kids growth rates ranged from 140 to 200 g/day in different breeds such as Majorera (Argüello et al., 2004), Verata (Fariña et al., 1989) and Damascus (Louca et al., 1977). Some authors have attributed the higher growth rate to a higher feed intake capacity in kids raised ad libitum (Sanz Sampelayo et al., 1987; Yan et al., 1993).
