Allah's saying;

وَإِنَّ لَكُمْ فِي الْأَنْعَامِ لَعِبْرَةً نُّسقِيكُم مِّمَّا فِي بُطُونِهَا وَلَكُمْ فِيهَا مَنَافِعُ كَثِيرَةٌ وَمِنْهَا تَأْكُلُونَ ﴿٢١﴾

وَعَلَيْهَا وَعَلَى الْفُلْكِ تُحْمَلُونَ ﴿٢٢﴾

And verily, in the cattle there is indeed a lesson for you. We give you to drink of that which is in their bellies. And there are, in them, numerous benefits for you, and of them you eat. And on them and on ships you are carried,

Here Allah mentions the benefits He has given to His servants in cattle, for they drink their milk which comes out from between dung and blood, they eat their meat and clothe themselves with their wool and hair, they ride on their backs and carry heavy burdens on them to far away lands, as Allah says:

وَتَحْمِلُ أَثْقَالَكُمْ إِلَى بَلَدٍ لَّمْ تَكُونُواْ بَـلِغِيهِ إِلاَّ بِشِقِّ الأَنفُسِ إِنَّ رَبَّكُمْ لَرَؤُوفٌ رَّحِيمٌ

And they carry your loads to a land that you could not reach except with great trouble to yourselves. Truly, your Lord is full of kindness, Most Merciful. (16:7)

أَوَلَمْ يَرَوْاْ أَنَّا خَلَقْنَا لَهُم مِمَّا عَمِلَتْ أَيْدِينَآ أَنْعـماً فَهُمْ لَهَا مَـلِكُونَ

وَذَلَّلْنَـهَا لَهُمْ فَمِنْهَا رَكُوبُهُمْ وَمِنْهَا يَأْكُلُونَ

وَلَهُمْ فِيهَا مَنَـفِعُ وَمَشَـرِبُ أَفَلاَ يَشْكُرُونَ

Do they not see that We have created for them of what Our Hands have created, the cattle, so that they are their owners. And We have subdued them unto them so that some of them they have for riding and some they eat. And in them there are benefits for them, and drink. Will they not then be grateful! (36:71-73)
